XPath not working to click a button from a Greasemonkey script
1
I would like to open a link that contains the word google. It looks like this:
<input class="submit" style="background: #409999; border-radius: 10px;" value="open" onclick="Open('143615', '1', 'https://www.google.de/');" type="submit">
I tried this Greasemonkey code:
var snapResults = document.evaluate("//input[contains(@onclick, 'test')]",document, null, XPathResult.UNORDERED_NODE_SNAPSHOT_TYPE, null);
for (var i = snapResults.snapshotLength - 1; i >= 0; i--) {
var elm = snapResults.snapshotItem(i);
// do stuff with elm
if (elm) //open the window, which contains "test"
{
elm.singleNodeValue.click(); //there is no effect ...
alert(i+". element opend");
}
else
{
alert(i+". Not found.");
}
}
It has no effect. I would like to open the window via Greasemonkey (click event ?)
When I use alert(elm.href); it says it is "undefined". But the XPath works when I try it in FirePath.

You say the XPath works, but elm.href is undefined in the GM script. This suggests that the <input> is added via AJAX.
Your script needs to use AJAX-aware techniques. Something like:
// ==UserScript==
// @name _Clicking "Open" buttons
// @include http://YOUR_SERVER.COM/YOUR_PATH/*
// @require http://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js
// @require https://gist.github.com/raw/2625891/waitForKeyElements.js
// @grant GM_addStyle
// ==/UserScript==
/*- The @grant directive is needed to work around a design change
introduced in GM 1.0. It restores the sandbox.
*/
waitForKeyElements ("input.submit[onclick*='open']", clickOpenBtn);
function clickOpenBtn (jNode) {
triggerMouseEvent (jNode[0], "click");
}
function triggerMouseEvent (node, eventType) {
var clickEvent = document.createEvent ('MouseEvents');
clickEvent.initEvent (eventType, true, true);
node.dispatchEvent (clickEvent);
}
