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.

function get_nodes_by_class(obj, class_name) {
    var node_list = [];
    var nodes = document.getElementsByTagName(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_class('div', 'hq');
 

now simply iterate over the 'hq_divs' and set innerHTML :)

kind regards

Thanks, I just made a little change and its working!!
:)

function get_nodes_by_class(obj, class_name, id_suffix) {
    var node_list = [];
    var nodes = document.getElementsByTagName(obj);
 
    for (var i = 0, n; n = nodes[i]; i++) {
        if (n.className == class_name && n.id.match(id_suffix)) {
            node_list.push(n);
        }
    }
 
    return node_list;
}
 
// usage
var hq_divs = get_nodes_by_class('div', 'hq', '_N');

ok :) to make it 'sure' working:

function get_nodes_by_class(obj, class_name, id_suffix) {
    var node_list = [];
    var nodes = document.getElementsByTagName(obj);
    var re = new RegExp(id_suffix + '$');
 
    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_class('div', 'hq', '_N');

kind regards

Why is id_suffix + '$' used?

[hsriat]

Ok, thanks:)

I got it...

Ok, thanks:)

I got it...

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