I capture file ids from triggers and check whether file exists in drive by. The below script throws exception and terminates the scripts abruptly if any of the trigger associated file is missing or if it is trash as mentioned in the Apps script openById documentation (which is natural). How do I overcome this?
function getForms() {
try {
var formsList = [];
var triggers = ScriptApp.getProjectTriggers();
for (var i = 0; i < triggers.length; i++) {
var fid = triggers[i].getTriggerSourceId();
if (fid) {
var title = FormApp.openById(fid).getTitle() == "" ? "Untitled" : FormApp.openById(fid).getTitle();
formsList.push([title, fid]);
}
}
return formsList;
} catch (e) {
;//catch errors
}
}
You may use the try catch statement wisely to avoid the Exception:
try {
if (fid) {
var title = FormApp.openById(fid).getTitle() == "" ? "Untitled" : FormApp.openById(fid).getTitle();
formsList.push([title, fid]);
}
} catch (e) {
Logger.log(e.message);
}
Use try catch inside for loop instead of outside in a useless place

The function block below runs perfectly whenever I run it form Google Apps Script Editor, but generates an Exception: Invalid argument: 0 when I run it from the appropriate site (docs.google.com).
I do not know what this exeption means, and also how to solve.
Could someone help me please?
function assignEventsColor() {
for (var i = 0; i < myevents.length; i++) {
var thisevent = myevents[i];
var title = thisevent.getTitle();
if (/Comp/.test(title)) { thisevent.setColor(CalendarApp.EventColor.PALE_BLUE); }
else if (/Matr/.test(title)) { thisevent.setColor(CalendarApp.EventColor.GREEN); }
else {}
}
}
I include myscript.js in the file http://site1.com/index.html like this:
<script src=http://site2.com/myscript.js></script>
Inside "myscript.js", I want to get access to the URL "http://site2.com/myscript.js". I'd like to have something like this:
function getScriptURL() {
// something here
return s
}
alert(getScriptURL());
Which would alert "http://site2.com/myscript.js" if called from the index.html mentioned above.
From http://feather.elektrum.org/book/src.html:
var scripts = document.getElementsByTagName('script');
var index = scripts.length - 1;
var myScript = scripts[index];
The variable myScript now has the script dom element. You can get the src url by using myScript.src.
Note that this needs to execute as part of the initial evaluation of the script. If you want to not pollute the Javascript namespace you can do something like:
var getScriptURL = (function() {
var scripts = document.getElementsByTagName('script');
var index = scripts.length - 1;
var myScript = scripts[index];
return function() { return myScript.src; };
})();
You can add id attribute to your script tag (even if it is inside a head tag):
<script id="myscripttag" src="http://site2.com/myscript.js"></script>
and then access to its src as follows:
document.getElementById("myscripttag").src
of course id value should be the same for every document that includes your script, but I don't think it is a big inconvenience for you.
Everything except IE supports
document.currentScript
Simple and straightforward solution that work very well :
If it not IE you can use document.currentScript
For IE you can do document.querySelector('script[src*="myscript.js"]')
so :
function getScriptURL(){
var script = document.currentScript || document.querySelector('script[src*="myscript.js"]')
return script.src
}
update
In a module script, you can use:
import.meta.url
as describe in mdn
I wrote a class to find get the path of scripts that works with delayed loading and async script tags.
I had some template files that were relative to my scripts so instead of hard coding them I made created the class to do create the paths automatically. The full source is here on github.
A while ago I had use arguments.callee to try and do something similar but I recently read on the MDN that it is not allowed in strict mode.
function ScriptPath() {
var scriptPath = '';
try {
//Throw an error to generate a stack trace
throw new Error();
}
catch(e) {
//Split the stack trace into each line
var stackLines = e.stack.split('\n');
var callerIndex = 0;
//Now walk though each line until we find a path reference
for(var i in stackLines){
if(!stackLines[i].match(/http[s]?:\/\//)) continue;
//We skipped all the lines with out an http so we now have a script reference
//This one is the class constructor, the next is the getScriptPath() call
//The one after that is the user code requesting the path info (so offset by 2)
callerIndex = Number(i) + 2;
break;
}
//Now parse the string for each section we want to return
pathParts = stackLines[callerIndex].match(/((http[s]?:\/\/.+\/)([^\/]+\.js)):/);
}
this.fullPath = function() {
return pathParts[1];
};
this.path = function() {
return pathParts[2];
};
this.file = function() {
return pathParts[3];
};
this.fileNoExt = function() {
var parts = this.file().split('.');
parts.length = parts.length != 1 ? parts.length - 1 : 1;
return parts.join('.');
};
}
if you have a chance to use jQuery, the code would look like this:
$('script[src$="/myscript.js"]').attr('src');
Following code lets you find the script element with given name
var scripts = document.getElementsByTagName( 'script' );
var len = scripts.length
for(var i =0; i < len; i++) {
if(scripts[i].src.search("<your JS file name") > 0 && scripts[i].src.lastIndexOf("/") >= 0) {
absoluteAddr = scripts[i].src.substring(0, scripts[i].src.lastIndexOf("/") + 1);
break;
}
}
document.currentScript.src
will return the URL of the current Script URL.
Note: If you have loaded the script with type Module then use
import.meta.url
for more import.meta & currentScript.src
Some necromancy, but here's a function that tries a few methods
function getScriptPath (hint) {
if ( typeof document === "object" &&
typeof document.currentScript === 'object' &&
document.currentScript && // null detect
typeof document.currentScript.src==='string' &&
document.currentScript.src.length > 0) {
return document.currentScript.src;
}
let here = new Error();
if (!here.stack) {
try { throw here;} catch (e) {here=e;}
}
if (here.stack) {
const stacklines = here.stack.split('\n');
console.log("parsing:",stacklines);
let result,ok=false;
stacklines.some(function(line){
if (ok) {
const httpSplit=line.split(':/');
const linetext = httpSplit.length===1?line.split(':')[0]:httpSplit[0]+':/'+( httpSplit.slice(1).join(':/').split(':')[0]);
const chop = linetext.split('at ');
if (chop.length>1) {
result = chop[1];
if ( result[0]!=='<') {
console.log("selected script from stack line:",line);
return true;
}
result=undefined;
}
return false;
}
ok = line.indexOf("getScriptPath")>0;
return false;
});
return result;
}
if ( hint && typeof document === "object") {
const script = document.querySelector('script[src="'+hint+'"]');
return script && script.src && script.src.length && script.src;
}
}
console.log("this script is at:",getScriptPath ())
Can't you use location.href or location.host and then append the script name?
I'm trying to grab data from chrome extension storage, but I can use them only in this function.
var help = new Array();
chrome.storage.local.get(null, function(storage){
//get data from extension storage
help = storage;
console.log(storage);
});
console.log(help); // empty
Result in console:
content.js:1 content script running
content.js:11 []
content.js:8 {/in/%E5%BF%97%E9%B9%8F-%E6%99%8F-013799151/: "link", /in/adam-
isaacs-690506ab/: "link", /in/alex-campbell-brown-832a09a0/: "link",
/in/alex-davies-41513a90/: "link", /in/alex-dunne-688a71a8/: "link", …}
Async function has won. I wrote my code again and now function is called hundreds time, i can not do this in dirrefent way
code:
console.log("content script running");
var cards = document.getElementsByClassName("org-alumni-profile-card");
var searchText = "Connect";
function check(exi, cards) {
chrome.storage.local.get(null, function(storage) {
for (var key in storage) {
if (storage[key] == "link" && key == exi) {
cards.style.opacity = "0.3";
}
}
});
}
for (var i = 0; i < cards.length; i++) {
var ctd = cards[i].getElementsByClassName(
"org-alumni-profile-card__link-text"
);
var msg = cards[i].getElementsByClassName(
"org-alumni-profile-card__messaging-button-shrunk"
);
if (ctd.length < 1 || msg.length > 0) {
cards[i].style.display = "none";
} else {
var exi = cards[i]
.getElementsByClassName("org-alumni-profile-card__full-name-link")[0]
.getAttribute("href");
check(exi, cards[i]);
}
}
SOLUTION of my problem
I wanted to delete this topic, but I can not, so instead of doing that, I'll put here what I've done finally.
The code above is wrong becouse, it was taking a list of links from website and for each from them script was grabbing a data from a storage... Which was stupid of course. I didn't see a solution which was so easy:
Put all your file's code in this function - it grabs data from storage just once.
I'm so sorry for messing up this wonderfull forum with topic like this.
Hope u'll forgive.
help will return undefined because it is referencing a asynchronous function and not the return value of that function. The content from storage looks to be printed on content.js:8, i.e. line 8.
I have a method that is supposed to loop over all of the controls on my page and return false if any one of them has a value other than empty string / null. This gets called as part of an OnSaveValidation. If the form is empty, they should be able to save.
function IsFormEmpty()
{
var ancestor = document.getElementById('PAIQIFunc'); //PAIQIFunc is the id of a div
var descendents = ancestor.getElementsByTagName('*');
var i = 0;
for (i = 0; i < descendents.length; ++i)
{
var e = descendents[i];
try
{
var eVal = $("#" + e).val();
// just check to make sure eVal has *some* value
if (eVal != '' || eVal != undefined || eVal != null)
return false;
}
catch (err){
//simply move on to next control...
}
}
return true;
}
Code sourced from Loop through all descendants of a div - JS only
In most cases, var eVal = $("#" + e).val(); throws an exception because it's a div or something like that. I'm only interested in the 108 drop down menus and 1 textbox on my form.
I set a breakpoint on my if statement and it was never hit. But descendents has like 1200 elements in it; I couldn't possibly step through it all trying to find what I'm looking for...
How else could I modify the code to check each control on the page?
EDIT: I should note that the web application is a C# / ASP.NET project using Razor views and we're using Telerik's Kendo web UI controls, not "vanilla" .NET controls if that makes a difference. So all of the controls are defined in the .cshtml file like so:
#(Html.Kendo().DropDownListFor(m => m.SomeProperty).HtmlAttributes(new { id = "cmbSomeProperty", #class = "k-dropdown-width-30", #tabIndex = "1", style = "width:60px" }).BindTo(ViewBag.SomePropertyDataSource).OptionLabel(" "))
You could try the following:
var hasValue = false;
var div = document.getElementById('PAIQIFunc');
$(div).find('input')
.each(function() { // iterates over all input fields found
if($.trim($(this).val()).length != 0) {
hasValue = true; // if field found with content
break;
}
});
if(hasValue === false) {
// save logic here
}
Hope this helps.
I'm getting the following error when attempting to get an enumerator for a collection of lists: "Uncaught Error: The collection has not been initialized. It has not been requested or the request has not been executed. It may need to be explicitly requested."
It happens on the line var listEnumerator = lists.getEnumerator(); it seems to me that there is an issue in my attempt to load lists into the client object with context.load(lists);
Here's the portion of my code that's causing the problem. I've marked the place just before the error is thrown.

I've looked at this question sharepoint javascript collection not initialized error which seems to be fairly similar to mine, but I'm having trouble implementing the solution provided there, making me think my error may be have a different cause.
I've also tried querying for the lists inside of the function that is throwing the error, but that doesn't seem to solve anything.
For a little background, these functions are attempting to read all lists from the app's host site, check to see if a specified list exists, and create a list if no matching list exists. If there's a better way of doing that than what I'm attempting, I'd be open to that too.
Any pointers?
Some things I've tried that don't seem to work:
Changing the Asynchronous query
context.executeQueryAsync(checkIfListExists(listToFind, hostweb, typeOfListToCreateIfTheListIsMissing), onQueryFailed);
to a Synchronous one.
context.executeQuery(checkIfListExists(listToFind, hostweb, typeOfListToCreateIfTheListIsMissing), onQueryFailed);
I've figured out an alternate, and shorter way to method of achieving the same goal I was trying to achieve before.
Instead of checking to see if a list does not already exist, I just try to create a list, and the Query fails to create a list if one is already there. (That's good because I don't want to overwrite the list if it is already there.)
I'm not totally sure if there are any undesired side effects of what I'm doing here, but in my tests it produced the desired behavior.

return singleParam[1];
