    <p>I am doing an editor where when user clicks a text or anything in the html document, I get it changed and record the changes in the database. It is a widget I am doing. Thus this is my question. Suppose I have an html element of the following structure:</p> <pre><code>&lt;html&gt; &lt;table&gt; &lt;tr&gt; &lt;td&gt;Apple&lt;/td&gt; &lt;td&gt;Pear&lt;/td&gt; &lt;/tr&gt; &lt;tr&gt; &lt;td&gt;Chicken&lt;/td&gt; &lt;td&gt;Beef&lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; &lt;div id="one"&gt; &lt;p&gt;Red&lt;/p&gt; &lt;p&gt;Orange&lt;/p&gt; &lt;/div&gt; &lt;div class="two"&gt; &lt;p&gt;Green&lt;/p&gt; &lt;p&gt;Purple&lt;/p&gt; &lt;/div&gt; &lt;div class="two"&gt; &lt;p&gt;Black&lt;/p&gt; &lt;p&gt;Blue&lt;/p&gt; &lt;/div&gt; &lt;/html&gt; </code></pre> <p>When user clicks Apple, the unique path is (Jquery):</p> <pre><code>table:eq(0)&gt;tr:eq(0)&gt;td:eq(1) </code></pre> <p>Suppose user clicks Red, the unique path is (Jquery):</p> <pre><code>div#one:eq(o) &gt; p:eq(0) </code></pre> <p>Is there any plugin readily available to uniquely identify the selectors?</p> <p>Currently I am using this function:</p> <pre><code>function getUniquePath2(node){ var parentEls = node.parentsUntil('[id]').add( node.closest('[id]') ) .map(function () { return this.tagName + (this.id ? '#' + this.id : ""); }) .get().join("&gt;"); return parentEls; } </code></pre> <p>However the above won't support and I have been researching for 4 days and I don't get an idea of how I should do it. The reason I am doing this because I want to track the user changes and change the elements as per the draft the user has made. The issue is, some elements do not have id's and the xpath conflicts with other elements. For instance if I want to change Green. How would it be unique anymore?</p>

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.
