Selector Th Jquery

I'm trying to understand how to use the Jquery selector https://learn.jquery.com/using-jquery-core/selecting-elements/ I have a table and I want to create an input within the moda

Solution 1:

table.row will look specifically at the table element and then of those elements, look for a class name of .row. I believe for your case, you want to look for nested .row classes in the table element so you should change it to $('table th'). I'm not sure what attribute scope is but if you want to use .row, you can define a <th class="row"> instead and then use $('table.row')

If you really want to use the attribute scope, you can also specify that in jQuery by doing ${'th[scope="row"]')

Solution 2:

You might want to have a look at the jQuery selectors. Elements with attributes having a specific value can be selected via [attributName="desiredValue"].

In your case: $('th[scope="row"]')

Solution 3:

To access <th scope="row">:

var thScopeRow = $('th[scope="row"]');

Solution 4:

scope is an attribute of <th>, not class, so the correct syntax would be $('th[scope="row"]'). In the snippet i selected this specific th using this method and changed the color of text just for example:

$('th[scope="row"]').css("color", "red");

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<table>
  <thead>
    <tr>
      <th>ID</th>
      <th>Edit</th>
    </tr>
  </thead>
  <tbody>
    <tr>
      <th scope="row">123</th>
      <th><a href="" data-toggle="modal" data-target="#formModal"><span class="oi" data-glyph="pencil"></span></a></th>
    </tr>
  </tbody>
</table>

UPDATE

"I inserted a class="update" in th: $('th[class="update"]')" If you are using <th class="row">123</th> and it's only one element on the page with such class, you can get it via $('.row')[0]. ([0] is needed because $('.row') will find ALL elements on the page with such class. So think about it as an array). If you have for example 2 elements on the page with such class and want to get the second, so use $('.row')[1] and so on.
