blocks|key|3838927|text|答案是将|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3838928|autoResize:true+|code-block|syntax|javascript|3838929|属性来创建对话框。为了使其正常工作，您不能为对话框设置任何高度。因此，如果在对话框的创建者方法中或通过任何样式设置固定的高度(以像素为单位)，则autoResize属性将不起作用。|3838930|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|K|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|L|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|M|8|@]|9|@]|A|$]]|$1|I|3|-4|5|6|7|N|8|@]|9|@]|A|$]]]|J|$]]

<p>The answer is to set the </p>

<pre><code>autoResize:true 
</code></pre>

<p>property when creating the dialog.  In order for this to work you cannot set any height for the dialog.  So if you set a fixed height in pixels for the dialog in its creator method or via any style the autoResize property will not work.</p>


blocks|key|4681146|text|更新：从jQuery+UI+1.8开始，工作解决方案(如第二条评论中提到的)是使用：|type|unstyled|depth|inlineStyleRanges|offset|length|style|BOLD|entityRanges|data|4681147|width:+'auto'|code-block|syntax|javascript|4681148|4681149|使用autoResize:true选项。我将举例说明：|4681150|++<div+id="whatup">
++++<div+id="inside">Hi+there.</div>
++</div>
+++<script>
+++++$('#whatup').dialog(
++++++"resize",+"auto"
+++++);
+++++$('#whatup').dialog();
+++++setTimeout(function()+{
++++++++$('#inside').append("Hello!<br>");
++++++++setTimeout(arguments.callee,+1000);
++++++},+1000);
+++</script>|4681151|下面是一个有效的示例：http://jsbin.com/ubowa|4681152|entityMap|0|LINK|mutability|MUTABLE|url|http://jsbin.com/ubowa^0|0|3|0|0|0|0|0|B|M|0|0^^$0|@$1|2|3|4|5|6|7|Z|8|@$9|10|A|11|B|C]]|D|@]|E|$]]|$1|F|3|G|5|H|7|12|8|@]|D|@]|E|$I|J]]|$1|K|3|-4|5|6|7|13|8|@]|D|@]|E|$]]|$1|L|3|M|5|6|7|14|8|@]|D|@]|E|$]]|$1|N|3|O|5|H|7|15|8|@]|D|@]|E|$I|J]]|$1|P|3|Q|5|6|7|16|8|@]|D|@$9|17|A|18|1|19]]|E|$]]|$1|R|3|-4|5|6|7|1A|8|@]|D|@]|E|$]]]|S|$T|$5|U|V|W|E|$X|Y]]]]

<p><strong>Update:</strong> As of jQuery UI 1.8, the working solution (as mentioned in the second comment) is to use:</p>

<pre><code>width: 'auto'
</code></pre>

<hr>

<p>Use the autoResize:true option. I'll illustrate:</p>

<pre><code>  &lt;div id="whatup"&gt;
    &lt;div id="inside"&gt;Hi there.&lt;/div&gt;
  &lt;/div&gt;
   &lt;script&gt;
     $('#whatup').dialog(
      "resize", "auto"
     );
     $('#whatup').dialog();
     setTimeout(function() {
        $('#inside').append("Hello!&lt;br&gt;");
        setTimeout(arguments.callee, 1000);
      }, 1000);
   &lt;/script&gt;
</code></pre>

<p>Here's a working example:

<p>Height is supported to auto.</p>

<p>Width is not!</p>

<p>To do some sort of auto get the size of the div you are showing and then set the window with.</p>

<p>In the C# code..</p>

<pre><code>TheDiv.Style["width"] = "200px";

    private void setWindowSize(int width, int height)
    {
        string widthScript =    "$('.dialogDiv').dialog('option', 'width', "    +   width   +");";
        string heightScript =   "$('.dialogDiv').dialog('option', 'height', "   +   height  + ");";

        ScriptManager.RegisterStartupScript(this.Page, this.GetType(),
            "scriptDOWINDOWSIZE",
            "&lt;script type='text/javascript'&gt;"
            + widthScript
            + heightScript +
            "&lt;/script&gt;", false);
    }

blocks|key|3839091|text|如果您需要在IE7中使用它，则不能使用undocumented,+buggy,+and+unsupported+{'width':'auto'}选项。相反，请将以下内容添加到.dialog()中|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|3839092|'open':+function(){+$(this).dialog('option',+'width',+this.scrollWidth)+}|code-block|syntax|javascript|3839093|.scrollWidth是否包含右侧填充取决于浏览器(火狐和Chrome不同)，所以你可以给.scrollWidth添加一个主观的“足够好”的像素数，或者用你自己的宽度计算函数来代替它。|3839094|您可能希望在.dialog()选项中包含width:+0，因为此方法永远不会减小宽度，而只会增加宽度。|3839095|经测试可在IE7、IE8、IE9、IE10、IE11、Firefox30、Chrome35和Opera22上运行。|3839096|entityMap|0|LINK|mutability|MUTABLE|url|http://bugs.jqueryui.com/ticket/4437#comment:9^0|1K|G|2F|9|J|10|0|0|0|0|C|1A|C|0|6|9|K|8|0|0^^$0|@$1|2|3|4|5|6|7|Y|8|@$9|Z|A|10|B|C]|$9|11|A|12|B|C]]|D|@$9|13|A|14|1|15]]|E|$]]|$1|F|3|G|5|H|7|16|8|@]|D|@]|E|$I|J]]|$1|K|3|L|5|6|7|17|8|@$9|18|A|19|B|C]|$9|1A|A|1B|B|C]]|D|@]|E|$]]|$1|M|3|N|5|6|7|1C|8|@$9|1D|A|1E|B|C]|$9|1F|A|1G|B|C]]|D|@]|E|$]]|$1|O|3|P|5|6|7|1H|8|@]|D|@]|E|$]]|$1|Q|3|-4|5|6|7|1I|8|@]|D|@]|E|$]]]|R|$S|$5|T|U|V|E|$W|X]]]]

<p>If you need it to work in IE7, you can't use the <a href="http://bugs.jqueryui.com/ticket/4437#comment:9" rel="nofollow">undocumented, buggy, and unsupported</a> <code>{'width':'auto'}</code> option. Instead, add the following to your <code>.dialog()</code>:</p>

<pre><code>'open': function(){ $(this).dialog('option', 'width', this.scrollWidth) }
</code></pre>

<p>Whether <code>.scrollWidth</code> includes the right-side padding depends on the browser (Firefox differs from Chrome), so you can either add a subjective "good enough" number of pixels to <code>.scrollWidth</code>, or replace it with your own width-calculation function.</p>

<p>You might want to include <code>width: 0</code> among your <code>.dialog()</code> options, since this method will never decrease the width, only increase it.</p>

<p>Tested to work in IE7, IE8, IE9, IE10, IE11, Firefox 30, Chrome 35, and Opera 22.</p>


<p>I have a JQuery UI dialog popup that displays a form.  By selecting certain options on the form new options will appear in the form causing it to grow taller.  This can lead to a scenario where the main page has a scrollbar and the JQuery UI dialog has a scrollbar.  This two-scrollbar scenario is unsightly and confusing for the user.</p>

<p>How can I make the JQuery UI dialog grow (and possibly shrink) to always fit its contents without showing a scrollbar?  I would prefer that only a scrollbar on the main page is visible.</p>
