Question

I want the same as the solution to this question but to determine whether a row actually exists in a table. I.e. I do not want to know whether a value exists in a table but I want to know whether the exact row (<tr ....></tr>) already exists.

Any ideas :)?

If you need just to check if table contains a specific row you could do like this:

if($("#rowID").length){
   //Horray you have the row you specified.
}
else{
   //what you should do when the row doesn't exist
}

Note that if($("#rowID").length) implies that length of the element not equal zero which means that it exists, you can also change the way you want to select the element with you could do something like that $("#tableID tr").length.

I hope this could help you
