    <p>I'm generating a table in js and using a function as follows for some of the headers:</p> <pre><code>function generateTableHeader(table) { var tr = document.createElement('tr'); var th = document.createElement('th'); th.onclick = function(){ toggleHidden("hide_header_" + table_count); }; th.appendChild(document.createTextNode(key)); tr.appendChild(th); table.appendChild(tr); } </code></pre> <p>My toggle hidden function just hides all elements of the class "hide_header_{some number}". It works fine.</p> <p>The problem is, I call this generateTableHeader function several times, creating headers for multiple tables - each time it's called table_count (global variable) is incremented and I expected this function to hide only the class of elements with the number it has when the onclick event is created. Instead, whenever I click on any of the headers, they always hide the last element created.</p> <p>The function is called 4 times to create 4 table headers in 4 different tables - each has a column of td's with the correct class name (i.e. "hide_header_1", "hide_header_2" and so on). When I click on the first header, the fourth table column is hidden/show. When I click the second, third, or fourth, still only the fourth column is hidden/show. I want each th click to hide only the td's in that table.</p> <p>It's as if the th onclick event I am creating is being overwritten each time I call this function, not sure why. Any ideas?</p> <p>Any help would be appreciated!</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.
