Date parsing issue

Enfernikus · 08-11-2009, 02:20 PM

I have this issue where I MUST use JavaScript to parse all dates on the page and reformat them, now I figured using the match method and replace the found results with the reformatted dates would be fine but it stands that my Regex is failing or I'm implementing the method incorrectly.

javascript Code:

var Matches = document.body.innerHTML.match(/\d{4}(\-)\d{2}(\-)\d{2}/);
alert(Matches); //Null

Anyone wants to have a looksie and see if possibly I'm just missing the glaringly obvious?

EDIT: Well than...Don't I feel stupid, I was missing the global search 'g' flag...I'll leave this here for anyone's future needs

You are executing the code before the document has finished loading, thus it's not picking any of the dates up.

javascript Code:

<body>
2009-08-22
<script>
var Matches = document.body.innerHTML.match(/\d{4}(\-)\d{2}(\-)\d{2}/);
alert(Matches); //Null
</script>
</body>

Or you could just tell the javascript to execute once the document has finished loading.

javascript Code:

<head>
<script>
window.onload = function()
{
    var Matches = document.body.innerHTML.match(/\d{4}(\-)\d{2}(\-)\d{2}/);
    alert(Matches); //Null
}
</script>
</head>
<body>
2009-08-22
</body>
