Question

Using jquery, how can I change the color of these elements to red if the textboxes contain defaultvalues and the ‘isrequired’ value is “Yes”?

<input type="text" value="Name" isrequired="Yes">
<input type="text" value="Address" isrequired="No">
<input type="text" value="Age" isrequired="Yes">

Answer 1

Change your input html to add an extra data-* attribute which store defult value

<input type="text" value="Name" data-default="Name" isrequired="Yes">
<input type="text" value="Address" data-default="Address" isrequired="No">
<input type="text" value="Age" data-default="Age" isrequired="Yes">

Jquery

$('input[isrequired=Yes]').each(function(){
if($(this).val()==$(this).data("default"))
{$(this).css('color', 'red');}
})

---

Update : With using defaultvalue property which is very new to me

$('input[isrequired=Yes]').each(function(){
  if (this.value == this.defaultValue) {$(this).css('color', 'red'); }

});

Much better ,cleaner.
