I want to delete a line if this <td> line contains only B in my lower code?

Question

Please check the code below. Here I delete the line if this line td contains the value "B". But the code below deletes all the lines.

JQuery

$(document).ready(function() { $("#mytable tr td:contains('B')").parent().remove(); }); 

HTML

 <table border="0" align="center" width="45%" cellpadding="2" cellspacing="2" id="mytable"> <tr> <td align="center" width="15%">A</td> <td align="center" width="15%">B</td> <td align="center" width="15%">C</td> </tr> <tr> <td align="center" width="15%">AA</td> <td align="center" width="15%">BB</td> <td align="center" width="15%">CC</td> </tr> <tr> <td align="center" width="15%">AAA</td> <td align="center" width="15%">BBB</td> <td align="center" width="15%">CCC</td> </tr> </table> 

Answer 1

To remove tr , where a td inside it contains ONLY "B"

 var searchString = 'B'; $("#mytable tr td:contains('" + searchString + "')").each(function() { if ($(this).text() == searchString) { $(this).parent().remove(); } }); 

Script example

To delete only td , which contains a 'B'

parent() places the selector in tr , which is then removed, along with all td elements. You do not need to use parent() here.

 $("#mytable tr td:contains('B')").remove();

Sandeep Try this.

  $(document).ready(function() { $("#mytable td").text(function(index, currentText) { if(currentText.trim()=='B') $(this).parent().remove(); }); }); 

Answer 3

That should work. Not sure if this is the best regex, but it works. It will remove the <tr> that contains the <td> with only one uppercase B http://jsfiddle.net/mV4z3/

 $('td').filter(function(){ return /^B$/.test($(this).text()); }).parent().remove();
