get_linkElement().click() not working in Firefox

[Bryan Kowalchuk]

I am simulating the click of a treview node in Javascript using

get_linkElement().click()

This works perfect in IE8, but Firefox 4.0 and Chrome cannot find the click() function and raises an error.

Any ideas on how I can work around this?

Thanks

Hi Bryan,

Well, this simply is not supported by Firefox.
Please, explain what exactly do you try to achieve and perhaps we will be able to help you find an alternative.

When user opens the form, treeview is displayed in a frame on the left side, content is in a frame on the right side.

The behaviour I would like is to have the first unselected content be displayed. I determine the first unselected treeview node, them simulate the user clicking the node using get_linkElement().click().

I suppose I could get the link element URL, and set the content frame href?

Hello Bryan Kowalchuk,

Is it a static link e.g. <a href="http://telerik.com">Click Here</a>, or is it a PostBack type of link e.g. <a href="javascript:SCRIPT">Click</a>?

Both require different approaches, but they can be solved using the following snippet:

function simulateClick(link) {

    if (!link) return;

    // Trigger onclick evenets from jQuery
    // $(link).click();

    if (link.href && link.href.indexOf("javascript:") == -1) {

        // Case 0: simple link
        // console.log("SimulateClick: Case 0")
        window.location = link.href;

    } else if (link.href && link.href.indexOf("javascript:") == 0) {

        var script = link.href.substring(11);

        // Case 1: <a href="javascript:...">...</a>
        // console.log("simulateClick: Case 1");
        if (script.indexOf("WebForm") == 0) {
            eval(unescape(script));
        } else {
            eval(script);
        }

    } else if (link.onclick) {

        // Case 2: <a onclick="...">...</a>
        // console.log("simulateClick: Case 2");
        eval(link.onclick);

    }
}

Let us know if this achieves the behaviour you want.
