    <p>I wrote a plugin sometime back for <strong><a href="http://meetselva.github.io/attrchange/">attrchange</a></strong> listener which basically adds a listener function on attribute change. Even though I say it as a plugin, actually it is a simple function written as a jQuery plugin.. so if you want.. strip off the plugin specfic code and use the core functions.</p> <p><strong>Note: This code doesn't use polling</strong> </p> <p>check out this simple demo <a href="http://jsfiddle.net/aD49d/">http://jsfiddle.net/aD49d/</a></p> <pre><code>$(function () { var prevHeight = $('#test').height(); $('#test').attrchange({ callback: function (e) { var curHeight = $(this).height(); if (prevHeight !== curHeight) { $('#logger').text('height changed from ' + prevHeight + ' to ' + curHeight); prevHeight = curHeight; } } }).resizable(); }); </code></pre> <p><strong>Plugin page:</strong> <a href="http://meetselva.github.io/attrchange/">http://meetselva.github.io/attrchange/</a></p> <p><strong>Minified version:</strong> (1.68kb)</p> <pre><code>(function(e){function t(){var e=document.createElement("p");var t=false;if(e.addEventListener)e.addEventListener("DOMAttrModified",function(){t=true},false);else if(e.attachEvent)e.attachEvent("onDOMAttrModified",function(){t=true});else return false;e.setAttribute("id","target");return t}function n(t,n){if(t){var r=this.data("attr-old-value");if(n.attributeName.indexOf("style")&gt;=0){if(!r["style"])r["style"]={};var i=n.attributeName.split(".");n.attributeName=i[0];n.oldValue=r["style"][i[1]];n.newValue=i[1]+":"+this.prop("style")[e.camelCase(i[1])];r["style"][i[1]]=n.newValue}else{n.oldValue=r[n.attributeName];n.newValue=this.attr(n.attributeName);r[n.attributeName]=n.newValue}this.data("attr-old-value",r)}}var r=window.MutationObserver||window.WebKitMutationObserver;e.fn.attrchange=function(i){var s={trackValues:false,callback:e.noop};if(typeof i==="function"){s.callback=i}else{e.extend(s,i)}if(s.trackValues){e(this).each(function(t,n){var r={};for(var i,t=0,s=n.attributes,o=s.length;t&lt;o;t++){i=s.item(t);r[i.nodeName]=i.value}e(this).data("attr-old-value",r)})}if(r){var o={subtree:false,attributes:true,attributeOldValue:s.trackValues};var u=new r(function(t){t.forEach(function(t){var n=t.target;if(s.trackValues){t.newValue=e(n).attr(t.attributeName)}s.callback.call(n,t)})});return this.each(function(){u.observe(this,o)})}else if(t()){return this.on("DOMAttrModified",function(e){if(e.originalEvent)e=e.originalEvent;e.attributeName=e.attrName;e.oldValue=e.prevValue;s.callback.call(this,e)})}else if("onpropertychange"in document.body){return this.on("propertychange",function(t){t.attributeName=window.event.propertyName;n.call(e(this),s.trackValues,t);s.callback.call(this,t)})}return this}})(jQuery) </code></pre>

    1. COThis solves the problem if you resize the div manually, this doesn't solve the original question no? If you add content dynamically it doesn't detect the height change: http://jsfiddle.net/aD49d/25/

    2. COI would also be interested in knowing if there was a way to make this work for dynamic content.

    3. CO@JoeCoder This attrchange code rely on DOM events triggered by the browser when there is an user action. However, dynamic contents in that example are included programmatically which unfortunately doesn't trigger any events. "Polling" seems to be another easier option here.. other option would be able to trigger manually after the dynamic content is included.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
