Question

I have the following HTML:

<div class="rep_tr0" id="row_2">

There is only one instance of a div with this id. How can I remove it with jQuery? I found the following code but I am not sure how to apply this:

$('.widgets').find(rowId).remove();

Answer 1

Grab by its id and then call remove.

 $('#row_2').remove();

The code you found is very similar. This says:

$('.widgets')    //find everything with a class of 'widgets'
  .find(rowId)   //now in all the widgets find something that has 'rowId'
  .remove();     //remove it

As rowId is a variable here (no quotes around it), I don’t know what the intention was from the person you found it from. But it needs to be a selector that jQuery can parse. Like # for an id or . for a class.
