    <p>For some reason I can't get <strong>jQuery html()</strong> function to work. I've tried the following:</p> <ol> <li><p>Find a specific div: </p> <p><code>var div = $("#divId");</code></p> <p>Outcome: works</p></li> <li><p>Test that i can use it with jQuery: </p> <p><code>alert($(div).attr("id"));</code></p> <p>Outcome: works; the id is presented</p></li> <li><p>Get the html within the div: </p> <p><code>alert($(div).html());</code></p> <p>Outcome: does not work; empty alert</p></li> <li><p>Get the html within the div with innerHTML:</p> <p><code>alert(document.getElementById($(div).attr("id")).innerHTML);</code></p> <p>Outcome: works; the div content is presented in the alert</p></li> </ol> <p>The actual code:</p> <pre><code>$(document).ready(function(){ var autocomp = namespace('mx.autocomp'); autocomp.overlay = (function() { var formId; var $searchValueComp; var $searchResultComp; function init(inFormId, inSearchValue){ formId = inFormId; $searchValueComp = $("#"+inFormId).find("[id$="+inSearchValue+"]"); $searchResultComp = $("#"+inFormId).find("[id$=searchResult]"); } function handleOverlay(){ var fn = window[formId + "OverlayWid"]; var result = document.getElementById($searchResultComp.attr("id")).innerHTML; if($searchValueComp.val().length==0){ fn.hide(); } // Test - This does not work as I get an empty alert alert($searchResultComp.html()); // Edit1: New test, this works. // When I use this javascript, I start with initializing the script from the page // using the "init(inFormId, inSearchValue)" function. The handleOverlay() function // is called through the "oncomplete='mx.autocomp.overlay.handleOverlay();'" of a // p:remoteCommand that executes a search in the db and then update the div called // "searchResultComp". // // Only reason I can think of why the code below works is that the jQuery object $test // is created after the div called "searchValueComp" has been updated by p:remoteCommand. // However, I don't understand why the jquery object "searchValueComp" wouldn't have // access to the same content as it should look for it first when the html() function // is called. Or is the content of the div searchValueComp set immediately when the // object is created in the "init" function? var $test = $("#"+formId).find("[id$=searchResult]"); alert($test.html()); // I need to check if the div: "searchResultComp" has any content. // As I don't get $searchResultComp.html() to work, I'm forced to // use the "getElementById" way instead. if(result.length==0){ fn.hide(); }else{ fn.show(); } } function print(text){ $("#textCheck").prepend(text + '\n'); } return { handleOverlay: handleOverlay, init: init }; })(); }); </code></pre> <p>What am I doing wrong?</p>

    2. COJust a detail: you don't need to wrap the *variable* `div` inside `$()` since you've already defined it as a jQuery object `$("#divId")`

    3. CODo not rewrap a jQuery object, that is a waste. `var div = $("#divId"); var id = div.attr("id"); var html = div.html();`

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).
