Trim the Contents of the Text Box


This tip will trim the contents in the input box of an HTML page using java script. Call the Trim function by sending the Textbox element as the parameter.

Example:
 
<form name=frm>
<input name=txtName onBlur="Trim
(document.frm.txtName)">
</form>
<script language=javascript>
function Trim(text)


		while(text.value.charAt(0)==' ')
		text.value=text.value.substring
(1,text.value.length )
		while(text.value.charAt
(text.value.length-1)==' ')
		text.value=text.value.substring
(0,text.value.length-1)

	}

</script>
