A simple java script error Handling Example.


We can use try catch block in java script for error handling.this is a example for use of try catch
<head>
<title></title>
<script type="text/javascript">
    var result; //Global Variable function CalCulate()
{
    try { //try Block
        var a = document.getElementById("txt1").value;
        var b = document.getElementById("txt2").value;
        var c = a / b;
        result = c;
    }
    catch (e) { //error handling  if you try to divide by zero it will generate exception. 
        result = e;
    }
    finally { //this block will execute always either work try block or catch block
        mydiv.innerHTML = result;
}
}
</script>
</head>
<body>
<div>
<input type="text" id="txt1" />
<input type="text" id="txt2" />
<input type="button" name="btn1" onclick="CalCulate()" value="Click" />
<div id="mydiv"></div>
</div>
</body>
</html>

Check match between two text box value with JavaScript.


<html>
<head><title></title>
<script type="text/javascript">
    function match() {
        var a = document.getElementById("txt1").value;
        var b = document.getElementById("txt2").value;

        if (a == b) {
            result.innerHTML = "match";
        }
        else {
            result.innerHTML = "not match";
        }
    }
</script>
</head>
<body>
<input type = "text" id = "txt1" />
<input type = "text" id = "txt2" onKeyUp="match()" />
<div id="result" />
