Remove whitespace from beginning and end of string of all textbox present in a webpage using jQuery or javascript
Question
Is it possible to remove whitespace from beginning and end of an string from all the textfields present in a webpage(or jsp page) using jQuery or javascript. For example .Suppose I have 50 textfields in a page and I want to check all these textfields for whitespace(beginning and end).I don't find it to be a good idea to call the function for every textfield individually. How can I do it without calling a function for each textfield.
Please suggest.

Can just use val() with a callback argument. It will loop over all elements for you:
$('input[type=text]').val(function( index, originalValue){
return $.trim(originalValue);
});

Get all the inputs from the page using jquery then run a loop, and for each element trim the value
<body>
<input type="text" value=" abc " >
<input type="text" value=" def " >
<input type="button" id="remove" value="Remove">
<script type="text/javascript">
$(document).ready(function(){
$('#remove').click(function(){
var inputs = $('input[type=text]');
$.each(inputs, function(index,input){
$(input).val($(input).val().trim())
});
});
});
</script>
</body>

You can execute this code:
$('input[type=text]').each(function (i, e) {
var $this = $(e);
$this.val($this.val().trim());
});
