Question

I have a button :

<button id="btn1">55</button>

And so I change the button value to test2

$('#btn1').text("22");

I want to show a background-picture if the buttons oldValue greater then the newValue.

How can I get the old value from this button?

“I have over 100 buttons and they are changing dynamically.”

Update: Isn’t there an event that fires before it changes?

Answer 1

You need to compare it before changing value.

For example

$('#btn1').text(function (index, old) {
   if (parseInt(old) > 22) {
    //change background image
   }
   return "22";
});
