Implement findNodesByAttribute Method

Usually, the findNode client-side methods (findNodeByText, findNodeByValue, findNodeByAttribute) return the first node that satisfies the search criterion.

Below is the implementation of a function which returns an array of nodes having the same value of a particular attribute:

JavaScript

function findNodesByAttribute(tree, attribute, value) {
    var nodes = tree.get_allNodes();
    var result = [];
    for (var i = 0; i < nodes.length; i++) {
        var node = nodes[i];
        if (node.get_attributes().getAttribute(attribute) == value) {
            Array.add(result, node);
        }
    }
    return result;

}

Here is a simple call to that function:

JavaScript

var tree = $find("<%= RadTreeView1.ClientID %>");
var nodes = findNodesByAttribute(tree, "readonly", "true");

for (var i = 0; i < nodes.length; i++) {
    alert(nodes[i].get_text());
}
