Conceal the top row of the second HTML table that does not contain any class or ID attributes

I have a scenario where I am working with two HTML tables within an iframe tag. These tables do not have any class or id attributes specified. My goal is to use jQuery to locate the first row of the second table and hide it. The structure of my tables is as follows: Note: Both tables are contained within the iframe tag, and I specifically need to hide the first row of the second table.

<table>
  <tr>
        <td> 1 </td>
         .
         .
         .
 </tr> 
</table>

The first row of the following table needs to be hidden:

<table>
   <tr>
     <td> This row should be hidden() </td>
   </tr>
  </table>

I have attempted various methods such as the one shown below:

$( "table[1] tr:first" ).css("display", "none");

However, these attempts have not yielded any results. Any assistance would be greatly appreciated.

Answer №1

If the <table> elements are not siblings, my recommendation would be:

$("table").eq(1).find("tr:first").hide();

Using the selector :nth-child(2) will only be effective if the second <table> is indeed the second child of its parent. It will select all instances of a t<table> that are the second child of their respective parents.

Answer №2

Adjusted comment on cf (jsfiddle updated)

To view the changes, please visit this jsFiddle link and look for the code snippet 

$('table').eq(1).find(tr:first').hide();

Based on the information provided by the OP in response to @DavidThomas' answer, it seems like the table is located inside an iframe. To access the content of the frame, you can try something similar to the code below:

    var framebody = $($('iframe')[0].contentDocument.body)
       ,frameSecondTable = framebody.find('table').eq(1);

You can observe how this works by referring to the jsFiddle demonstration.

Answer №3

Check out this solution:

 $( "table:nth-child(2) tr:first" ).css("display", "none" );

Answer №4

To hide the first row in a table, you can apply nth-child along with jQuery hide method.

$( "table:nth-child(2) tr:first" ).hide();
