Question

I want to add a comma after copy pasting string into input

$("#keywords").bind('paste', function() {

   var a=$("#keywords").val();
   alert(a);
  });

I tried the above code to check if the pasted value is passed into variable. In alert it is displaying empty value. How can i know if the value of the pasted string is passed into variable and then append comma to the variable.

Here is the fiddle

Answer 1

The paste event is fired before the pasted text is available as a value property on the textbox. You need to wait a few milliseconds, and then just add the comma to the value, like so:

$("#keywords").on('paste', function() {
    var self = this, timer = setTimeout(function() {
        self.value=self.value+',';
    }, 300);
});​
