问题:

With many sites leveraging jQuery UI, there are some major shortcomings that have to be overcome because jQuery UI does not support responsive design and there's a longstanding bug when maxWidth is used in conjunction with width:'auto'.

So the question remains, how to make jQuery UI Dialog responsive?

回答1:

Below is how I achieved a responsive jQuery UI Dialog.

To do this, I added a new option to the config - fluid: true, which says to make the dialog responsive.

I then catch the resize and dialog open events, to change the max-width of the dialog on the fly, and reposition the dialog.

You can see it in action here: http://codepen.io/jasonday/pen/amlqz

Please review and post any edits or improvements.

// Demo: http://codepen.io/jasonday/pen/amlqz
// movemaine@gmail.com

$("#content").dialog({
    width: 'auto', // overcomes width:'auto' and maxWidth bug
    maxWidth: 600,
    height: 'auto',
    modal: true,
    fluid: true, //new option
    resizable: false
});


// on window resize run function
$(window).resize(function () {
    fluidDialog();
});

// catch dialog if opened within a viewport smaller than the dialog width
$(document).on("dialogopen", ".ui-dialog", function (event, ui) {
    fluidDialog();
});

function fluidDialog() {
    var $visible = $(".ui-dialog:visible");
    // each open dialog
    $visible.each(function () {
        var $this = $(this);
        var dialog = $this.find(".ui-dialog-content").data("ui-dialog");
        // if fluid option == true
        if (dialog.options.fluid) {
            var wWidth = $(window).width();
            // check window width against dialog width
            if (wWidth < (parseInt(dialog.options.maxWidth) + 50))  {
                // keep dialog from filling entire screen
                $this.css("max-width", "90%");
            } else {
                // fix maxWidth bug
                $this.css("max-width", dialog.options.maxWidth + "px");
            }
            //reposition dialog
            dialog.option("position", dialog.options.position);
        }
    });

}

EDIT

Updated approach: https://github.com/jasonday/jQuery-UI-Dialog-extended

The repository above also includes options for:

  • Click outside of dialog to close
  • Hide title bar
  • hide close button
  • responsive (to address above)
  • scale width & height for responsive (ex: 80% of window width)

Setting maxWidth on create works fine:

$( ".selector" ).dialog({
  width: "auto",
  // maxWidth: 660, // This won't work
  create: function( event, ui ) {
    // Set maxWidth
    $(this).css("maxWidth", "660px");
  }
});

No need for jQuery or Javascript. CSS solves everything for this.

This is my project solution for a responsive jquery dialog box. Default width and height, then max width and height for as small as the browser shrinks. Then we have flexbox to cause the contents to span the available height.

Fiddle: http://jsfiddle.net/iausallc/y7ja52dq/1/

EDIT

Updated centering technique to support resizing and dragging

.ui-dialog {
    z-index:1000000000;
    top: 0; left: 0;
    margin: auto;
    position: fixed;
    max-width: 100%;
    max-height: 100%;
    display: flex;
    flex-direction: column;
    align-items: stretch;
}
.ui-dialog .ui-dialog-content {
    flex: 1;
}

I gathered these codes from several sources and I put them together. This is how I came up with a responsive jQuery UI Dialog. Hope this helps..

I have managed to to a responsive dialog with old 

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">

like this

            var dWidth = $(window).width() * 0.9;
            var dHeight = $(window).height() * 0.9; 

            $('#dialogMap').dialog({
                autoOpen: false,
                resizable: false,
                draggable: false,
                closeOnEscape: true,
                stack: true,
                zIndex: 10000,
                width: dWidth,
                height: dHeight,    
                modal: true,
                open:function () {          

                }
            });
            $('#dialogMap').dialog('open');

Resize the window on JSFiddle result and click "Run".



回答6:

If your site is restricted to a max size, then below approach will work. Attach a css style to your dialog.

.alert{
    margin: 0 auto;
    max-width: 840px;
    min-width: 250px;
    width: 80% !important;
    left: 0 !important;
    right: 0 !important;
}

$('#divDialog').dialog({
    autoOpen: false,
    draggable: true,
    resizable: true,
    dialogClass: "alert",
    modal: true
});


回答7:

I am not sure that my simple solution solves the problem of this question, but it works for what I am trying to do:

$('#dialog').dialog(
{
    autoOpen: true,
    width: Math.min(400, $(window).width() * .8),
    modal: true,
    draggable: true,
    resizable: false,
});

That is, the dialog opens with a 400px width, unless the width of the window requires a smaller width.

Not responsive in the sense that if the width is narrowed the dialog shrinks, but responsive in the sense that on a specific device, the dialog will not be too wide.



回答8:

$("#content").dialog({
    width: 'auto',
    create: function (event, ui) {
        // Set max-width
        $(this).parent().css("maxWidth", "600px");
    }
});

This Worked for me



回答9:

I have managed to do responsive dialog like this. Because use percent on maxWidth looked weird.

var wWidth = $(window).width();
var dWidth = wWidth * 0.8;

$('.selector').dialog({
    height: 'auto',
    width: 'auto',
    create: function(){
        $(this).css('maxWidth', dWidth);
    }
});


回答10:

Thanks for the posts! This saved me a great deal of time.

I would also like to add, though, that I was getting some funky positioning when the dialog first opened on certain screen sizes. If you encounter such an error, try doing something like this:

if (wWidth < dialog.options.maxWidth + 50) {
    // keep dialog from filling entire screen
    $this.css("max-width", "90%");

    // ADDED
    $this.css("left", "5%");
} else {
    // fix maxWidth bug
    $this.css("max-width", dialog.options.maxWidth);

    // ADDED
    var mLeft = (wWidth - dialog.options.maxWidth) / 2;
    $this.css("left", mLeft + "px");
}

Hopefully this saves someone a headache =)



回答11:

I just found a solution for this issue.

I pasted my css style, hope this can help someone

.ui-dialog{
  position: fixed;

  left: 0 !important;
  right: 0 !important;

  padding: rem-calc(15);
  border: 1px solid #d3dbe2;
  box-shadow: 0 0 10px rgba(0, 0, 0, 0.2);

  max-width: rem-calc(620);
  top: rem-calc(100) !important;

  margin: 0 auto;
  width: calc(100% - 20px) !important;
}


回答12:

Thank you, this makes responsive, but I still had an issue with the dialog being offcenter b/c my content (django form template) was loading after the dialog opened. So Instead of $( "#my-modal" ).load(myurl).dialog("open" );, I call $( "#my-modal" ).dialog("open" ); Then in the dialog, I add the option 'open' and call a load, then your fluidDialog() function:

in the dialog options (modal, fluid, height..etc):

open: function () {
    // call LOAD after open
    $("#edit-profile-modal").load(urlvar, function() {
    // call fluid dialog AFTER load
    fluidDialog();
});


回答13:

The accepted solution is rather buggy and overengineered imo. I came up with dialogResize which is cleaner and more straightforward for my purposes.

Implement like so:

$("#dialog").dialogResize({
  width: 600,
  height: 400,
  autoOpen: true,
  modal: true
});
