I'm trying to add ma to a string and show that into label through following function :

HTML :

<input type="text" onkeyup="addCommas(this.value);" /> <br /><br />
<label id="result">Result: </label>

JS

function addCommas(nStr)
{
    nStr += '';
    x = nStr.split('.');
    x1 = x[0];
    x2 = x.length > 1 ? '.' + x[1] : '';
    var rgx = /(\d+)(\d{3})/;
    while (rgx.test(x1)) {
        x1 = x1.replace(rgx, '$1' + ',' + '$2');
    }
    var result = x1 + x2;
    document.getElementById('result').value = result;
}

JsFiddle

But won't show the result into label.

What am i doing wrong?

Reset to default 5

Label doesn't use value to assign values. It uses innerHTML. Try the below.

document.getElementById('result').innerHTML = result;

As pointed out in ments, it is better to use textContent or innerText options to set value (only for plain text) as they are safer than innerHTML.You can use it as shown below.

document.getElementById('result').textContent = result;

or

document.getElementById('result').innerText = result;

innerText property is not supported by FireFox and it uses the textContent property. Hence, the below method will work across browsers.

var resultDiv = document.getElementById('result');

if (typeof resultDiv.innerText === 'string') {
    resultDiv.innerText = result;
}
else {
    resultDiv.textContent = result;
}

Sources:

  1. IE8 label update via javascript issue
  2. 'innerText' works in IE, but not in Firefox

Try this

 document.getElementById('result').innerHTML = result;

instead of .value, use .innerHTML

Use innerHTML instead of value:

document.getElementById('result').innerHTML = result;

Also note, to use inline event handlers in JSFIDDLE you must set the second dropdown to one of the nowrap options.
