On a MouseEvent instance, we have a property called path, it might look like this:
Does anybody know if there is a reliable way to translate this path array into an XPath? I assume that this path data is the best data to start from? Is there a library I can use to do the conversion?
This library looks promising, but it doesn't use the path property of an event: https://github.com/johannhof/xpath-dom
There's not a unique XPath to a node, so you'll have to decide what's the most appropriate way of constructing a path. Use IDs where available? Numeral position in the document? Position relative to other elements?
See getPathTo() in this answer for one possible approach.
PS: Taken from Javascript get XPath of a node
Another option is to use SelectorGadget from below link
https://dv0akt2986vzh.cloudfront.net/unstable/lib/selectorgadget.js
The actual code for the DOM path is at
https://dv0akt2986vzh.cloudfront.net/stable/lib/dom.js
Usage: on http://google.com
elem = document.getElementById("q")
predict = new DomPredictionHelper()
predict.pathOf(elem)
// gives "body.default-theme.des-mat:nth-child(2) div#_Alw:nth-child(4) form#f:nth-child(2) div#fkbx:nth-child(2) input#q:nth-child(2)"
predict.predictCss([elem],[])
// gives "#q"

The value of this is determined by how a function is called.
this will point to window in setTimeout. Use .bind to have specified values as this context.
The bind() method creates a new function that, when called, has its this keyword set to the provided value, with a given sequence of arguments preceding any provided when the new function is called.

I need to add a function which is going to check for touch or click detection on the screen. If there is no touch after some seconds, all game has to restart from the beginning. How can I do that?
I hide that start and stop buttons on the design. So with window.onload=runGame game starts automatically when its loaded. But need to be restart if children live the game play when its not finished. For example, if there is no touch after 120 seconds, all code has to restart from beginning. Or there is buildCard function in the code. This timer can trigger this function also. I will be glad for any kind of help cause this is for kids.
You can use debounce technique like shown in below snippet. I have added click event but you can add touch specific events also. timer() will be triggered every 120 secs if click event is not triggered i.e if user doesn't click or touch. I could not run your code to test. Please let me know if this doesn't work.

Specific line having issues:

UPDATE:
New issue. Uncaught SyntaxError: Illegal return statement engine.js:282
Lines 281-282 for debugging purposes:
if (!rules)
return console.error("Expose: cant find corresponding rule")
UPDATE 2:
This is my final issue. And this whole thing will be resolved.
It looks like its another return error. But i do not understand how to properly return this part.
Heres the error but its basically the same.
Uncaught SyntaxError: Illegal return statement engine.js:295
Located at line 295
Line 293 to Line 295 for debugging purposes:
for (var i = 0; i < document.head.childNodes.length; i++)
if (tryReplace(document.head.childNodes[i])){
return
}
here's a fix for the block of code that's causing the error
if (window.top == window.self) {
if (document.readyState !== 'loading') {
// don't return
console.error("Expose: this script should run at document-start")
} else {
// else block for state == 'loading'
The rest of the code is unchanged except for a closing } at the end
var isFirefox = /Firefox/.test(navigator.userAgent)
// Stage 1: Find corresponding rule
var rules
for (var i = 0; i < allRules.length; i++)
if (allRules[i].hostname.indexOf(window.location.hostname) !== -1) {
rules = allRules[i]
break
}
if (!rules)
return console.error("Expose: cant find corresponding rule")

} else {

return observer.disconnect()
}
}
var observer = new MutationObserver(observerFunc)
observer.observe(document.head, {

})
}
} // added this closing }
}
I use codemirror and jquery to "simulate" an xml-editor in the browser. Some xml-Tags include an "on"-attribute with two possible values (true or false). Would it be possible to toggle these values at an onclick event? Is a codemirror/jquery plugin available?
EDIT :
self-coded solution.
function attrtoggle(){
var pos = editor.getCursor();
var line = editor.getLine(pos.line);
var index = line.indexOf("on=");
if(index > 0){
//define range
if ( pos.ch -3 < index || pos.ch - 9 > index)
return false;
var len = 10;
var replace_pos = index + 4;
if(line.charAt(replace_pos) == "t"){
//insert false
line = line.replace('true', 'false');
} else{
//insert true
line = line.replace('false', 'true');
}
edited = pos.line;
editor.setLine(pos.line, line);
}
}
Just add an event-handler for the onclick event
$(".CodeMirror").attr("onclick","javascript:attrtoggle()");
By far not perfect (bad design and so on) , but it works as expected:
Just trigger the function at an onclick event.
function attributeToggle(){
var transitions = {
"on": {
"false":"true",
"true":"false"
}
}
var pos = editor.getCursor(); // object {line, ch}
var token = editor.getTokenAt(pos);
var line = editor.getLine(pos.line);
try{
var prev_pos = token.start - 1;
var prev_token = editor.getTokenAt({'line':pos.line, 'ch':prev_pos});
if(prev_token.className == "attribute")
var attr = prev_token.string;
else
return false;
if(typeof transitions[attr] === "undefined") //nothing to replace
return false;
var current_val = token.string.toLowerCase().replace(/(['"])/g, "");
if(typeof transitions[attr][current_val] === "undefined")
return false;
var line_new = line.substring(0, token.start) + \
"\"" + transitions[attr][current_val] + "\"" + line.substring(token.end);
editor.setLine(pos.line, line_new);
} catch (e){
console.log(e);
}
}
