Strip out space from user input using JavaScript (ReplaceAll)
While I was trying to strip out all space from user input using JavaScript, First I tried with using simple replace function like var strDest = strSrc.replace(" ",""). But, I see the result that it only replaces the first occurance of the space in source string. Intrestingly, I googled and found one solution to remove all the spaces from a string that is " / /gi" parameter. Here is the JavaScript to strip out spaces from a string/user input:
<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
<title>Untitled Page</title>
<script type="text/javascript" language="javascript">
function CheckSpace()
{
var strSrc = document.getElementById('<%=TextBox1.ClientID%>').value;
//here we need to give the string/char that we need to replace from source string
//in my case it is space for I gave a space between two forward slashes as var spaceFix = / /gi;
//if you want to replace for example all "a" then it should be written as var spaceFix = /a/gi;
var spaceFix = / /gi;
var strDest = strSrc.replace(spaceFix,"");
alert(strDest);
return false;
}
</script>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
<asp:Button ID="Button1" runat="server" Text="Button" OnClientClick="return CheckSpace();" /></div>
</form>
</body>
