    <p>This following code snippet works fine using jQuery1.2.3, but it doesn’t work with latest version of jQuery:</p> <pre><code>$.getJSON(url,{str: $$.val() }, function(j){ if (j.length &gt; 0) { var options = '&lt;option value=""&gt;' +params.firstOption+ '&lt;/option&gt;'; for (var i = 0; i &lt; j.length; i++) { options += '&lt;option value="' + j[i].optionValue + '"&gt;' + j[i].optionDisplay + '&lt;/option&gt;'; } } $dest.removeAttr('disabled') .html(options) .find('option:first') .attr('selected', 'selected'); }); </code></pre> <p>Please note that this above code is actually part of a jQuery plugin for cascading drop down list. It produces desired result if I use jQuery1.2.3. The full plugin code is as follows:</p> <pre><code>(function($){ $.fn.linkedSelect = function(url,destination,params) { var params = $.extend({ firstOption : 'Please Select', loadingText : 'Loading...' },params); var $dest = $(destination); return this.each(function(){ $(this).bind('change', function() { var $$ = $(this); $dest.attr('disabled','false') .append('&lt;option value=""&gt;' +params.loadingText+ '&lt;/option&gt;') .ajaxStart(function(){ $$.show(); }); $.getJSON(url,{str: $$.val() }, function(j){ alert('User clicked on this.'); if (j.length &gt; 0) { var options = '&lt;option value=""&gt;' +params.firstOption+ '&lt;/option&gt;'; for (var i = 0; i &lt; j.length; i++) { options += '&lt;option value="' + j[i].optionValue + '"&gt;' + j[i].optionDisplay + '&lt;/option&gt;'; } } $dest.removeAttr('disabled') .html(options) .find('option:first') .attr('selected', 'selected'); }); // end getJSON }); // end change }); // end return each }; // end function })(jQuery); </code></pre> <p>Please note that it can't generate the following alert message </p> <pre><code>alert('User clicked on this.'); </code></pre> <p>what is written inside the getJSON function for debugging purpose if I use latest version of jQuery. And I have also traced using JS debugger, it can't step into the getJSON function if I use latest version of jQuery. But, it shows this alert message if I use jQuery1.2.3. </p> <p>In error console, warning messages are: </p> <pre><code>Warning: reference to undefined property b.p.height Source File: http://localhost//js/jquery.jqGrid.min.js Line: 99 Warning: reference to undefined property b.p.serializeGridData Source File: http://localhost/js/jquery.jqGrid.min.js Line: 62 Warning: reference to undefined property jQuery.event.triggered Source File: http://localhost/js/jquery1.7.js Line: 2924 Warning: reference to undefined property elem[jQuery.expando] Source File: http://localhost/js/jquery1.7.js Line: 1719 </code></pre> <p>What should I change to adapt with latest version of jQuery. Thank you. </p>

    1. COWelcome to Stack Overflow! "It doesn't work" is *never* a good error description. Please describe what goes wrong, what error messages you get, etc.

    2. COso where exactly is the failure? you can add some console.log to the code to find out and exactly what is the latest version of jquery you are trying to use and how did you load it?

    3. COCould you explain more in depth how it isn't working and what your test case is? You are testing the exact same inputs on the exact same code, and the only difference is the jQuery version, right?

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).
