JQuery :contains find first and single instance of a string

The Jquery :contains function is very good in that it will find an instance of a string. However what if I am performing this contains: function on a table which in the second column contains the following.

0
20
01
44

The code below when run on the above table with the column values will return every row where there is a "0". SO basically every row except "44".

$('.application>tbody>tr') 
.show() 
.f开发者_运维技巧ind("td:nth-child(2).not(':contains("0")') 
.parent() 
.hide() 
} 

How would one go about making the code return only the rows where there is a single "0" and not the other rows which contain a "0" such as "20".

Hope someone can point me in the right direction. Thank you.

You can use .filter() for this, for example:

$('.application>tbody>tr') 
.show() 
.find("td:nth-child(2)")
.filter(function() { return $.text([this]) != "0"; })
.parent() 
.hide()

This compares the exact text, rather than a substring.
