Trying to replace contents of a Div, with no luck
Ive tried to use the Dom model with no bloody luck, getElementByID just doesnt work for me.
I loathe to resort to a regex but not sure what else to do.
The idea is to replace a <div id="content_div"> all sorts </div> with a new <div id="content_div"> NEW ALL SORTS HERE </div> and keep anything that was before or after it in the string.
The string is a partial HTML string and more specifically开发者_JS百科 out of the wordpress Posts DB.
Any ideas?
UPDATE: I tagged this question PHP but probably should of mentioned Im looking for a PHP solution only.
Update: Code Example
$content = ($wpdb->get_var( "SELECT `post_content` FROM $wpdb->posts WHERE ID = {$article[post_id]}" ));
$doc = new DOMDocument();
$doc->validateOnParse = true;
$doc->loadHTMLFile($content);
$element = $doc->getElementById('div_to_edit');
So Ive tried a whole lot of code and this is what Ive got so far, probably not right but Ive been hacking at it for a little while now.
You're right: getElementByID doesn't work.
Try getElementById() instead. Javascript is case sensitive.
ok i assume $content is a snippet? then this may be all you need:
$doc = new DOMDocument();
$doc->validateOnParse = true;
$doc->loadHTMLFile('<html><body>' . $content . '</body></html>');
$element = $doc->getElementById('div_to_edit');
remember that you must have a valid webpage and that means full HTML tree:
<html>
<head>
<script type="text/javascript">
function changeText(div){
document.getElementById(div).innerHTML = 'my new text';
}
</script>
</head>
<body>
--- your body ---
<div id="DIV_ID">old text</div>
<input type="button" onclick="chageText('DIV_ID');" value="Click me" />
</body>
</html>remember that you have to call getElementById with:
<script type="text/javascript"> // as from HTML5 you can use only <script>
document.getElementById("DIV_ID").innerHTML = 'my new text';
</script>Try this..
var myDiv = document.getElementById('content_div');
myDiv.innerHTML = "NEW ALL SORTS HERE";
