当我尝试过滤表时，jQuery.trim无法正常工作

Question

I have a textbox to put text in order to filter an html table. I want to trim the textbox contents before filter the table:

Demo : http://jsfiddle.net/QFQ5k/94/

The line that makes the filtering is:

return $(this).find("[zip^='"+ $.trim($("#txtbox").val())+"']").length>0;

EDIT: It works succesfully, i tested it wrongly, but I want that alone blank space shows all table rows.

Answer 1

I have updated my fiddle: http://jsfiddle.net/QFQ5k/101/

now you can see the triming there. I just added some lines after the keyup event.

$("#txtbox").keyup(function () {
var a = $.trim($(this).val());
$(this).val(a);

I hope this solves what you want to achieve.

Better use quicksearch for your requirement. I hope below sample helps you a bit.

Quicksearch jquery plug-in

Answer 3

I filter only if there is something typed in the textbox, els i don't.

if($("#txtbox").val().length >0){
   // Filtering
}
