Select dropdown with fixed width cutting off conte

2019-01-03 02:32发布

The issue:

Some of the items in the select require more than the specified width of 145px in order to display fully.

Firefox behavior: clicking on the select reveals the dropdown elements list adjusted to the width of the longest element.

IE6 & IE7 behavior: clicking on the select reveals the dropdown elements list restricted to 145px width making it impossible to read the longer elements.

The current UI requires us to fit this dropdown in 145px and have it host items with longer descriptions.

Any advise on resolving the issue with IE?

The top element should remain 145px wide even when the list is expanded.

Thank you!

The css:

select.center_pull {
    background:#eeeeee none repeat scroll 0 0;
    border:1px solid #7E7E7E;
    color:#333333;
    font-size:12px;
    margin-bottom:4px;
    margin-right:4px;
    margin-top:4px;
    width:145px;
}

Here's the select input code (there's no definition for the backend_dropbox style at this time)

<select id="select_1" class="center_pull backend_dropbox" name="select_1">
<option value="-1" selected="selected">Browse options</option>
<option value="-1">------------------------------------</option>
<option value="224">Option 1</option>
<option value="234">Longer title for option 2</option>
<option value="242">Very long and extensively descriptive title for option 3</option>
</select>

Full html page in case you want to quickly test in a browser:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>dropdown test</title>

<style type="text/css">
<!--
select.center_pull {
    background:#eeeeee none repeat scroll 0 0;
    border:1px solid #7E7E7E;
    color:#333333;
    font-size:12px;
    margin-bottom:4px;
    margin-right:4px;
    margin-top:4px;
    width:145px;
}
-->
</style>
</head>

<body>
<p>Select width test</p>
<form id="form1" name="form1" method="post" action="">
<select id="select_1" class="center_pull backend_dropbox" name="select_1">
<option value="-1" selected="selected">Browse options</option>
<option value="-1">------------------------------------</option>
<option value="224">Option 1</option>
<option value="234">Longer title for option 2</option>
<option value="242">Very long and extensively descriptive title for option 3</option>
</select>
</form>
</body>
</html>

I did Google about this issue but didn't find any best solution ,So Created a solution that works fine in all browsers.

just call badFixSelectBoxDataWidthIE() function on page load.

function badFixSelectBoxDataWidthIE(){
    if ($.browser.msie){
      $('select').each(function(){
    if($(this).attr('multiple')== false){
      $(this)
          .mousedown(function(){
               if($(this).css("width") != "auto") {
                   var width = $(this).width();
                   $(this).data("origWidth", $(this).css("width"))
                          .css("width", "auto");
                   /* if the width is now less than before then undo */
                   if($(this).width() < width) {
        $(this).unbind('mousedown');
                       $(this).css("width", $(this).data("origWidth"));
                   }
               }
           })
           /* Handle blur if the user does not change the value */
           .blur(function(){
               $(this).css("width", $(this).data("origWidth"));

           })
           /* Handle change of the user does change the value */
           .change(function(){
               $(this).css("width", $(this).data("origWidth"));

           });
        }
      });
    }
    }

I've got yet another contribution to this. I wrote this a while back that you may find helpful: http://dpatrickcaldwell.blogspot.com/2011/06/giantdropdown-jquery-plugin-for-styling.html

It's a jquery plugin to make a styleable unordered list backed by the hidden select element.

The source is on github: https://github.com/tncbbthositg/GiantDropdown

You'd be able to handle behaviors and styles on the UL that you can't with the SELECT. Everything else should be the same because the select list is still there, it's just hidden but the UL will use it as a backing data store (if you will).

A workaround if you don't care about the strange view after an option is selected (i.e. Select to jump to a new page):

<!-- Limit width of the wrapping div instead of the select and use 'overflow: hidden' to hide the right part of it. -->
<div style='width: 145px; overflow: hidden; border-right: 1px solid #aaa;'>
  <select onchange='jump();'>
    <!-- '&#9660;(▼)' produces a fake dropdown indicator -->
    <option value=''>Jump to ... &#9660;</option>
    <option value='1'>http://stackoverflow.com/questions/682764/select-dropdown-with-fixed-width-cutting-off-content-in-ie</option>
    ...
  </select>
</div>

Best solution: css + javascript

http://css-tricks.com/select-cuts-off-options-in-ie-fix/

var el;

$("select")
  .each(function() {
    el = $(this);
    el.data("origWidth", el.outerWidth()) // IE 8 can haz padding
  })
  .mouseenter(function(){
    $(this).css("width", "auto");
  })
  .bind("blur change", function(){
    el = $(this);
    el.css("width", el.data("origWidth"));
  });

The jquery BalusC's solution improved by me. Used also: Brad Robertson's comment here.

Just put this in a .js, use the wide class for your desired combos and don't forge to give it an Id. Call the function in the onload (or documentReady or whatever).
As simple ass that :)
It will use the width that you defined for the combo as minimun length.

function fixIeCombos() {
    if ($.browser.msie && $.browser.version < 9) {
    var style = $('<style>select.expand { width: auto; }</style>');
    $('html > head').append(style);

    var defaultWidth = "200";

    // get predefined combo's widths.
    var widths = new Array();
    $('select.wide').each(function() {
        var width = $(this).width();
        if (!width) {
        width = defaultWidth;
        }
        widths[$(this).attr('id')] = width;
    });

    $('select.wide')
    .bind('focus mouseover', function() {
        // We're going to do the expansion only if the resultant size is bigger
        // than the original size of the combo.
        // In order to find out the resultant size, we first clon the combo as
        // a hidden element, add to the dom, and then test the width.
        var originalWidth = widths[$(this).attr('id')];

        var $selectClone = $(this).clone();
        $selectClone.addClass('expand').hide();
        $(this).after( $selectClone );
        var expandedWidth = $selectClone.width()
        $selectClone.remove();
        if (expandedWidth > originalWidth) {
        $(this).addClass('expand').removeClass('clicked');
        }
    })
    .bind('click', function() {
        $(this).toggleClass('clicked'); 
    })
    .bind('mouseout', function() {
        if (!$(this).hasClass('clicked')) {
        $(this).removeClass('expand');
        }
    })
    .bind('blur', function() {
        $(this).removeClass('expand clicked');
    })
    }
}

Here is a solution that actually works.

It sets the width in IE and doesn't mess up your page layout and doesn't close the dropdown when you mouse over the select options like some of the other solutions on this page.

You will need however to change the margin-right value and width values to match what you have for your select fields.

Also you can replace the $('select') with $('#Your_Select_ID_HERE') to only effect a specific select field. As well you will need to call the function fixIESelect() on the body onload or via jQuery using DOM ready as I did in my code below:

//////////////////////////
// FIX IE SELECT INPUT //
/////////////////////////
window.fixIESelect_clickset = false;
function fixIESelect()
{
 if ($.browser.msie)
 {
  $('select').mouseenter(function ()
  {
   $(this).css("width","auto");
   $(this).css("margin-right","-100");
  });
  $('select').bind('click focus',function ()
  {
   window.fixIESelect_clickset = true;
  });
  $('select').mouseout(function ()
  {
   if(window.fixIESelect_clickset != true)
   {
    $(this).css("width","93px");
    window.fixIESelect_clickset = false;
   }
  });
  $('select').bind('blur change',function ()
  {
   $(this).css("width","93px");
  });
 }
}
/////////////
// ONLOAD //
////////////
$(document).ready(function()
{
 fixIESelect();
});
