Javascript function to only allow integers in the textbox


Hi

try this another example to make TextBox accept only integer so we will write the following Javascript code :-

<script type = “text/javascript” language = “javascript”>
function CheckTextBox(i)
{
    if(i.value.length>0)
    {
    i.value = i.value.replace(/[^\d]+/g, ”);
    }
}
</Script>

and to use this script dd this function to “onkeyup” event for TextBox

TextBox1.Attributes.Add(“onkeypress”, “CheckTextBox(this)”);

Hope this helps

Good Luck
