wildcard in js?

[hsriat]

There are few DIVs in my HTML who have ids in the form of randomString+ '_N'

eg
[html]<div id="fhgse_N" class="hq"></div>
<div id="dgf5g_N" class="hq"></div>
<div id="ns65h_N" class="hq"></div>[/html]

I need to provide innerHTML to them by splitting the response text string from AJAX.

Since I don't know what the random strings (prefixed to the IDs) would be, but I know that the suffix is _N, the class name is hq and tag name is div.

How can I set innerHTML of these DIVs?
Wildcard could help in that.

[CODE=javascript]function get_nodes_by_cl ass(obj, class_name) {
var node_list = [];
var nodes = document.getEle mentsByTagName( obj);

for (var i = 0, n; n = nodes[i]; i++) {
if (n.className == class_name) {
node_list.push( n);
}
}

return node_list;
}

// usage
var hq_divs = get_nodes_by_cl ass('div', 'hq');
[/CODE]
now simply iterate over the 'hq_divs' and set innerHTML :)

kind regards

[CODE=javascript]function get_nodes_by_cl ass(obj, class_name, id_suffix) {
var node_list = [];
var nodes = document.getEle mentsByTagName( obj);

for (var i = 0, n; n = nodes[i]; i++) {
if (n.className == class_name && n.id.match(id_s uffix)) {
node_list.push( n);
}
}

return node_list;
}

// usage
var hq_divs = get_nodes_by_cl ass('div', 'hq', '_N');[/code]

ok :) to make it 'sure' working:

[CODE=javascript]function get_nodes_by_cl ass(obj, class_name, id_suffix) {
var node_list = [];
var nodes = document.getEle mentsByTagName( obj);
var re = new RegExp(id_suffi x + '$');

for (var i = 0, n; n = nodes[i]; i++) {
if (n.className == class_name && n.id.match(re)) {
node_list.push( n);
}
}

return node_list;
}

// usage
var hq_divs = get_nodes_by_cl ass('div', 'hq', '_N');[/code]
kind regards

Why is id_suffix + '$' used?

Ok, thanks:)

Ok, thanks:)

I got it...

it is used for the regEx to check from the end of the string ... ;)
