Help with JQuery conditional statement

I am trying to run some JQuery script on a particular page but only if a certain page loads.

The Scenario: We have one page that loads (i.e., webpage.aspx) and it loads different content based on the referring click. (i.e., webpage.aspx?contentId=1, webpage.aspx?contentId=2, webpage.aspx?c开发者_JS百科ontentId=3, etc). Here is my problem. I need to have a particular part of the page removed if only one specific contentId is pulled. I am trying to do this in JQuery and can't seem to figure it out.

Here's what i have been working with so far. I realize it's not correct but hopefully it gives you a starting point to work with.

Thanks.

CODE:

$(window).load(function() {
   var $deleteNewRow = $("div.col.w140 tbody:first").find("td:first").parent().remove();
   if($('#dealer-info h1').indexOf('Ferrari') != -1) {
      $deleteNewRow
   }
});

What you store in your $deleteNewRow variable isn't the jQuery method, that method will already execute. You want to do that method in your if statement, something like this (note that you are also missing the .text() in the if statement):

$(window).load(function() {
   if($('#dealer-info h1').text().indexOf('Ferrari') != -1) {
      $("div.col.w140 tbody:first").find("td:first").parent().remove();
   }
});

You can use jQuery :contains selector to check for the existence. Here is the docs. Then to delete find the element and then use remove.

$("div.col.w140 tbody:first").find("td:first").parent().remove();
