Question

here is my code

$(document).ready(function () {
    var val1 = $("#Content_txtYorum").val();

    function checkChanges() {
        var val2 = $("#Content_txtYorum").val();
        console.log(val1 + " " + val2);  // for test
        if (val1 != val2)
            alert($("#Content_txtYorum").val());
        setTimeout(function () 
        {
            checkChanges();
        }, 3000);

    }

    checkChanges();
});

i try to write my textChange event.. but variable val2 never changes when i write something to textbox.
what is the problem ?

thanks..

Answer 1

you can just add a handler to the .change() event of your text box!

$('#Content_txtYorum').change(function(){
   alert( $('#Content_txtYorum').val());

});

check out the fiddle:

EDIT: as per your comment, keyup should work for you:

$('#Content_txtYorum').keyup(function(){
   alert( $('#Content_txtYorum').val());

});

the fiddle is updated as well

EDIT: as per your new comment, keyup should work for you:

$('.ClassOnYourDoTNetFields').keyup(function(){
   alert( $(this).val());

});
