jQuery UI - Close Dialog When Clicked Outside

问题:

I have a jQuery UI Dialog that gets displayed when specific elements are clicked. I would like to close the dialog if a click occurs anywhere other than on those triggering elements or the dialog itself.

Here's the code for opening the dialog:

$(document).ready(function() {
    var $field_hint = $('<div></div>')
        .dialog({
            autoOpen: false,
            minHeight: 50,
            resizable: false,
            width: 375
        });

    $('.hint').click(function() {
        var $hint = $(this);
        $field_hint.html($hint.html());
        $field_hint.dialog('option', 'position', [162, $hint.offset().top + 25]);
        $field_hint.dialog('option', 'title', $hint.siblings('label').html());
        $field_hint.dialog('open');
    });
    /*$(document).click(function() {
        $field_hint.dialog('close');
    });*/
});

If I uncomment the last part, the dialog never opens. I assume it's because the same click that opens the dialog is closing it again.

Final Working Code
Note: This is using the jQuery outside events plugin

$(document).ready(function() {
    // dialog element to .hint
    var $field_hint = $('<div></div>')
            .dialog({
                autoOpen: false,
                minHeight: 0,
                resizable: false,
                width: 376
            })
            .bind('clickoutside', function(e) {
                $target = $(e.target);
                if (!$target.filter('.hint').length
                        && !$target.filter('.hintclickicon').length) {
                    $field_hint.dialog('close');
                }
            });

    // attach dialog element to .hint elements
    $('.hint').click(function() {
        var $hint = $(this);
        $field_hint.html('<div style="max-height: 300px;">' + $hint.html() + '</div>');
        $field_hint.dialog('option', 'position', [$hint.offset().left - 384, $hint.offset().top + 24 - $(document).scrollTop()]);
        $field_hint.dialog('option', 'title', $hint.siblings('label').html());
        $field_hint.dialog('open');
    });

    // trigger .hint dialog with an anchor tag referencing the form element
    $('.hintclickicon').click(function(e) {
        e.preventDefault();
        $($(this).get(0).hash + ' .hint').trigger('click');
    });
});

回答1:

Check out the jQuery Outside Events plugin

Lets you do:

$field_hint.bind('clickoutside',function(){
    $field_hint.dialog('close');
});

回答2:

Sorry to drag this up after so long but I used the below. Any disadvantages? See the open function...

$("#popup").dialog(
{
    height: 670,
    width: 680,
    modal: true,
    autoOpen: false,
    close: function(event, ui) { $('#wrap').show(); },
    open: function(event, ui) 
    { 
        $('.ui-widget-overlay').bind('click', function()
        { 
            $("#popup").dialog('close'); 
        }); 
    }
});

Forget using another plugin:

Here are 3 methods to close a jquery UI dialog when clicking outside popin:

If the dialog is modal/has background overlay: http://jsfiddle.net/jasonday/6FGqN/

jQuery(document).ready(function() {
    jQuery("#dialog").dialog({
        bgiframe: true,
        autoOpen: false,
        height: 100,
        modal: true,
        open: function(){
            jQuery('.ui-widget-overlay').bind('click',function(){
                jQuery('#dialog').dialog('close');
            })
        }
    });
}); 

If dialog is non-modal Method 1: method 1: http://jsfiddle.net/jasonday/xpkFf/

 // Close Pop-in If the user clicks anywhere else on the page
                     jQuery('body')
                      .bind(
                       'click',
                       function(e){
                        if(
                         jQuery('#dialog').dialog('isOpen')
                         && !jQuery(e.target).is('.ui-dialog, a')
                         && !jQuery(e.target).closest('.ui-dialog').length
                        ){
                         jQuery('#dialog').dialog('close');
                        }
                       }
                      );

Non-Modal dialog Method 2: http://jsfiddle.net/jasonday/eccKr/

  $(function() {
            $( "#dialog" ).dialog({
                autoOpen: false, 
                minHeight: 100,
                width: 342,
                draggable: true,
                resizable: false,
                modal: false,
                closeText: 'Close',
                  open: function() {
                      closedialog = 1;
                      $(document).bind('click', overlayclickclose);
                  },
                  focus: function() {
                      closedialog = 0;
                  },
                  close: function() {
                      $(document).unbind('click');
                  }



        });

         $('#linkID').click(function() {
            $('#dialog').dialog('open');
            closedialog = 0;
        });

         var closedialog;

          function overlayclickclose() {
              if (closedialog) {
                  $('#dialog').dialog('close');
              }

              //set to one because click on dialog box sets to zero
              closedialog = 1;
          }


  });

回答4:

Just add this global script, which closes all the modal dialogs just clicking outsite them.

$(document).ready(function()
{
    $(document.body).on("click", ".ui-widget-overlay", function()
    {
        $.each($(".ui-dialog"), function()
        {
            var $dialog;
            $dialog = $(this).children(".ui-dialog-content");
            if($dialog.dialog("option", "modal"))
            {
                $dialog.dialog("close");
            }
        });
    });;
});

回答5:

$(".ui-widget-overlay").click (function () {
    $("#dialog-id").dialog( "close" );
});

Fiddle showing the above code in action.

回答6:

I had to do two parts. First the outside click-handler:

$(document).on('click', function(e){
    if ($(".ui-dialog").length) {
        if (!$(e.target).parents().filter('.ui-dialog').length) {
            $('.ui-dialog-content').dialog('close');
        }
    }
}); 

This calls dialog('close') on the generic ui-dialog-content class, and so will close all dialogs if the click didn't originate in one. It will work with modal dialogs too, since the overlay is not part of the .ui-dialog box.

The problem is:

1. Most dialogs are created because of clicks outside of a dialog
2. This handler runs after those clicks have created a dialog and bubbled up to the document, so it immediately closes them.

To fix this, I had to add stopPropagation to those click handlers:

moreLink.on('click', function (e) {
    listBox.dialog();
    e.stopPropagation(); //Don't trigger the outside click handler
});

回答7:

This question is a bit old, but in case someone wants to close a dialog that is NOT modal when user clicks somewhere, you can use this that I took from the JQuery UI Multiselect plugin. The main advantage is that the click is not "lost" (if user wants to click on a link or a button, the action is done).

$myselector.dialog({
            title: "Dialog that closes when user clicks outside",
            modal:false,
            close: function(){
                        $(document).off('mousedown.mydialog');
                    },
            open: function(event, ui) { 
                    var $dialog = $(this).dialog('widget');
                    $(document).on('mousedown.mydialog', function(e) {
                        // Close when user clicks elsewhere
                        if($dialog.dialog('isOpen') && !$.contains($myselector.dialog('widget')[0], e.target)){
                            $myselector.dialog('close');
                        }            
                    });
                }                    
            });

回答8:

You can do this without using any additional plug-in

var $dialog= $(document.createElement("div")).appendTo(document.body);
    var dialogOverlay;

    $dialog.dialog({
        title: "Your title",
        modal: true,
        resizable: true,
        draggable: false,
        autoOpen: false,
        width: "auto",
        show: "fade",
        hide: "fade",
        open:function(){
            $dialog.dialog('widget').animate({
                width: "+=300", 
                left: "-=150"
            });

//get the last overlay in the dom
            $dialogOverlay = $(".ui-widget-overlay").last();
//remove any event handler bound to it.
            $dialogOverlay.unbind();
            $dialogOverlay.click(function(){
//close the dialog whenever the overlay is clicked.
                $dialog.dialog("close");
            });
        }
    });

Here $dialog is the dialog. What we are basically doing is to get the last overlay widget whenever this dialog is opened and binding a click handler to that overlay to close $dialog as anytime the overlay is clicked.

回答9:

no need for the outside events plugin...

just add an event handler to the .ui-widget-overlay div:

jQuery(document).on('click', 'body > .ui-widget-overlay', function(){
     jQuery("#ui-dialog-selector-goes-here").dialog("close");
     return false;
});

just make sure that whatever selector you used for the jQuery ui dialog, is also called to close it.. i.e. #ui-dialog-selector-goes-here

回答10:

This doesn't use jQuery UI, but does use jQuery, and may be useful for those who aren't using jQuery UI for whatever reason. Do it like so:

function showDialog(){
  $('#dialog').show();
  $('*').on('click',function(e){
    $('#zoomer').hide();
  });
}

$(document).ready(function(){

  showDialog();    

});

So, once I've shown a dialog, I add a click handler that only looks for the first click on anything.

Now, it would be nicer if I could get it to ignore clicks on anything on #dialog and its contents, but when I tried switching $('*') with $(':not("#dialog,#dialog *")'), it still detected #dialog clicks.

Anyway, I was using this purely for a photo lightbox, so it worked okay for that purpose.

回答11:

The given example(s) use one dialog with id '#dialog', i needed a solution that close any dialog:

$.extend($.ui.dialog.prototype.options, {
    modal: true,
    open: function(object) {
        jQuery('.ui-widget-overlay').bind('click', function() {              
            var id = jQuery(object.target).attr('id');
            jQuery('#'+id).dialog('close');
        })
    }
});

Thanks to my colleague Youri Arkesteijn for the suggestion of using prototype.

回答12:

For those you are interested I've created a generic plugin that enables to close a dialog when clicking outside of it whether it a modal or non-modal dialog. It supports one or multiple dialogs on the same page.

回答13:

I use this solution based in one posted here:

var g_divOpenDialog = null;
function _openDlg(l_d) {

  // http://stackoverflow.com/questions/2554779/jquery-ui-close-dialog-when-clicked-outside
  jQuery('body').bind(
   'click',
   function(e){
    if(
      g_divOpenDialog!=null 
      && !jQuery(e.target).is('.ui-dialog, a')
      && !jQuery(e.target).closest('.ui-dialog').length
    ){
      _closeDlg();
    }
   }
  );

  setTimeout(function() {
    g_divOpenDialog = l_d;
    g_divOpenDialog.dialog();
  }, 500);
}
function _closeDlg() {
  jQuery('body').unbind('click');
  g_divOpenDialog.dialog('close');
  g_divOpenDialog.dialog('destroy');
  g_divOpenDialog = null;
}

回答14:

I had same problem while making preview modal on one page. After a lot of googling I found this very useful solution. With event and target it is checking where click happened and depending on it triggers the action or does nothing.

Code Snippet Library site

$('#modal-background').mousedown(function(e) {
var clicked = $(e.target);  
if (clicked.is('#modal-content') || clicked.parents().is('#modal-content')) 
    return; 
} else {  
 $('#modal-background').hide();
}
});

回答15:

This is the only method that worked for me for my NON-MODAL dialog

$(document).mousedown(function(e) {
    var clicked = $(e.target); // get the element clicked
    if (clicked.is('#dlg') || clicked.parents().is('#dlg') || clicked.is('.ui-dialog-titlebar')) {
        return; // click happened within the dialog, do nothing here
    } else { // click was outside the dialog, so close it
        $('#dlg').dialog("close");
    }
});

回答16:

İt's simple actually you don't need any plugins, just jquery or you can do it with simple javascript.

$('#dialog').on('click', function(e){
  e.stopPropagation();
});
$(document.body).on('click', function(e){
  master.hide();
});

回答17:

I don't think finding dialog stuff using $('.any-selector') from the whole DOM is so bright.

Try

$('<div />').dialog({
    open: function(event, ui){
        var ins = $(this).dialog('instance');
        var overlay = ins.overlay;
        overlay.off('click').on('click', {$dialog: $(this)}, function(event){
            event.data.$dialog.dialog('close');
        });
    }
});

You're really getting the overlay from the dialog instance it belongs to, things will never go wrong this way.

回答18:

With the following code, you can simulate a click on the 'close' button of the dialog (change the string 'MY_DIALOG' for the name of your own dialog)

$("div[aria-labelledby='ui-dialog-title-MY_DIALOG'] div.ui-helper-clearfix a.ui-dialog-titlebar-close")[0].click();

回答19:

Smart Code: I am using following code so that every thing remains clear and readable. out side body will close the dialog box.

$(document).ready(function () {
   $('body').on('click', '.ui-widget-overlay', closeDialogBox);
});

function closeDialogBox() {
    $('#dialog-message').dialog('close');
}
