The placeholder gets converted into value upon toUpperCase operations. - IE 9

[vishwasjois]

Code Snippet :

var caller = event.target || event.srcElement;
 $(caller).val($(caller).val().toUpperCase());

Using Backbone.js + Jquery 1.9.1
In this case $(caller) is just the element from which the event is triggered.
$(caller) will be something like this :-

<input type="text" name="name123" id="name123" placeholder="Serial Number, IMEI, MEID" maxlength="20" autocomplete="off" spellcheck="false" class="customInput">

to handle this issue. I 'm manually checking with below code.

if ($('#name123').val() !=  $('#name123').attr('placeholder')) {
// Send value to server
}

it will be good if the toUpperCase / toLowerCase scenarios are handled by the plugin.
Otherwise the plugin works as expected.

Thanks.

Also observed the following :
The placeholder text turns to be the Input field's value when you manually call $('#ElementId').blur();
