Is there a way to call a specific javascript function in a single js file for a specific page URL?

I have a question, i wanted to know if there is a way to call a specific function if a specific page URL is opened?
#shop_modal is in http://myurl/liste-boutique.php
#dep_modal is in http://myurl/index.php
Right now, i have Error when i try to open the #dep_modal because JS cant find #shop_modal on that page same page, so it does not execute below that.
I think AJAX can help figuring this out, otherwise i will have to split the code in 2 JS files, which i don't want to
const new_shop = $("#new_shop")[0];
const save_shop = $("#shop_form")[0];
const close_shop_modal = $("#close_shop_modal")[0];
const new_departement = $("#new_dep")[0];
const save_departement = $("#dep_form")[0];
const close_dep_modal = $("#close_dep_modal")[0];
// I want this to be called if the URL is http://my-URL/liste-boutique.php
new_shop.addEventListener('click', function(){
$("#shop_modal")[0].style.visibility = "visible";
})
// I want this to be called if the URL is http://my-URL/index.php
new_departement.addEventListener('click', function(){
$("#dep_modal")[0].style.visibility = "visible";
})
i need to ask question, but i don't know what to change here
Thanks again !!

You can check window.location.href. E.g.
if (window.location.href === 'http://my-URL/liste-boutique.php') {
new_shop.addEventListener('click', function(){
$("#shop_modal")[0].style.visibility = "visible";
});
}

Instead of checking the url, check if the element you want to find is on the page:
var $new_shop = $("#new_shop");
if ($new_shop.length > 0) {
var new_shop = $new_shop[0];
new_shop.addEventListener('click', function(){
$("#shop_modal")[0].style.visibility = "visible";
})
}
(I've used $ prefix on $new_shop to show it's a jquery object just for clarity)
Or, using your code as-is:
var new_shop = $("#new_shop")[0];
if (new_shop != undefined) {
new_shop.addEventListener...
Alternatively, if you use jquery, you don't need to worry about it as it will automatically not apply if the element doesn't exist:
$("#new_shop").click(() => { $("#shop_modal)").fadeIn(); });

LocalStorage data appearing in console but not in the DOM

I am currently building a to-do list app and I have already saved the data using the localStorage API.
The desired data, however, appears in the console whenever I console.log it but it still doesn't save in the DOM.
I also added the getItem() function and logged it into the console and I can still view it in the console, find here:
getItem content in the console
But it just doesn't store in the browser
Seeing this, it is in your inclination that it should have stored in the DOM and the content still remains after reloading but that just isn't the case here.
This function below adds a new item to the list, it also deletes and crosses out completed items too:
let id = 0;
function addTaskFunc() {
const aTask = `
<div class="task" id="task-${id}">
<button class="done__btn">
<i class="far fa-check-square"></i>
</button>
<p>${box.value}</p>
<button class="priority">Make priority</button>
<button class="cancel__btn">
<i class="far fa-times-circle"></i>
</button>
</div>
`;
const x = box.value;
if (x) {
taskList.insertAdjacentHTML('afterbegin', aTask);
box.value = '';
;
let cid = id;
const cancelBtn = document.querySelector(`#task-${id} .cancel__btn`);
cancelBtn.addEventListener('click', () => {
deleteItem(cid);
});
let cid2 = id;
// code for marking out an item as done
let cid3 = id;
// code for appending an item to the top of DOM
let cid4 = id;
persistData(cid4);
readData(cid4);
id++;
}
}
newTask.addEventListener('click', addTaskFunc); // Button to activate the function
persistData = id => {
const el = document.querySelector(`#task-${id}`);
localStorage.setItem('addedTasks222', el.innerHTML);
};
readData = id => {
const el = document.querySelector(`#task-${id}`);
const saved = localStorage.getItem('addedTasks222');
if (saved) el.innerHTML = saved;
console.log(el.innerHTML); // This line of code appears in the console
}
I also tried doing it this way inside of the addTaskFunc:
const r = document.querySelector(`#task-${id} .task`);
r.addEventListener('load', () => {
persistData(cid4);
readData(cid4);
});
When I try it with the method above I get the error code in the console:
Cannot read property of addEventListener of null.
I feel there is something wrong somewhere but I just cannot seem to find out where I am missing it.
One last thing, the localStorage only seems to store only one item into the key. Do I need a loop to sort that out?

you can store an array in the local storage like this
localStorage.setItem('array', JSON.stringify(YOURARRAY))
and then you can load that with
var restoredArray = JSON.parse(localStorage.getItem('array'));

sorry for the time..
So I was looking in to your code, and appears that you have some problems..
1- The first one I saw, was in the persistData() function. Accidentally you are just selecting one task to store with document.querySelector(.task);
to select all you need to use document.querySelectorAll(.task), this will return you an array. Because of that you only store one task.
2- Secondly is that you are trying to store html. with .innerHtml, and the innerHtml of your (".class") is buttons and etc.. You should store values.
3- At the end, when you are trying to print the data, you do document.querySelector(.task), and as you can see its returning you undefined, that's because you haven't a .task div yet.
So How you can appropriately make your app work.
1- The first thing you need to do is creating an array variable up on your js file.
let tasks = [];
2-That array will be used to store the values of your tasks with something like this
function addItem(){
let value = item.value; //you need to define the item some way
tasks.push(value);
print() //a function to print the values;
persistData() // store the array
}
3-To print the tasks
function print(){
tasks.forEach(task => {
let div = document.createElement("div");
div.innerHTML = `copy your html task to here, use ${task} to print the task value`
})
}
4-Store the tasks
function persistData(){
localStorage.setItem('addedTasks', tasks); //store the array
};
function readData(){
if (typeof(Storage) !== "undefined") { //check if the browser has localStorage
tasks = localStorage.getItem('addedTasks'); //update your array
print();
} else {
//No Web Storage message
}
};
5- Just run readData() when you load your document with
document.addEventListener("DOMContentLoaded", function(event) {
readData();
});
I hope that I can help

addPreSearch filter not applying

I am trying to use the addPreSearch function to add a custom filter to a lookup field, but the function does not seem to execute fully before the results of the lookup are displayed. The code for this looks something like this:
function onFieldChange(executionContext) {
var formContext = executionContext.getFormContext();
formContext.getControl("test_code").removePreSearch(testFunctionFilter);
formContext.getControl("test_code").addPreSearch(testFunctionFilter);
}
function testFunctionFilter(executionContext) {
var formContext = executionContext.getFormContext();
var record1 = formContext.getAttribute("test_record1_link").getValue(); //get linked record
var record1FullId, record1Id, stringRecordId, idLength, record1Guid = "0";
if (record1 != null) {
record1Id = record1[0].id;
record1Id = record1FullId.slice(1, -1);
stringRecordId = record1FullId.toString();
idLength = stringRecordId.length;
//Guid when retrieved from tablet does not have parenthesis on each end
if (idLength == 36) {
record1Guid = record1FullId;
} else {
record1Guid = recordId;
}
}
var fieldValue;
Xrm.WebApi.retrieveRecord("test_record1", record1Guid, "?$select=test_field1")
.then(function(result1) {
fieldValue = result1.test_field;
var options = generateOptions(executionContext, fieldValue); //creates option string using retrieved fieldValue
Xrm.WebApi.retrieveMultipleRecords("test_record2", options)
.then(function(result) {
var codes = getCodes(result2, fieldValue);
filter = generateFilter(codes, record1Guid); //creates custom filter using provided parameters
console.log(filter); //displays filter correctly
formContext.getControl("test_codelookup").addCustomFilter(filter, "test_coderecord"); //not working?
});
});
}
The filter is generated correctly using the functions used above whose definitions aren't shown. That isn't the issue. I've tried creating a separate test function where I hard coded one of the filters that the function above generated, and the lookup displayed the correct results. The testFunctionFilter should run to completion before the results of the lookup are displayed, correct? Because the filter is logged to the console after the results of the lookup appear. Are the nested asynchronous Xrm.WebApi calls somehow causing the issue? I'm not quite sure what is wrong. Please advise.

You are right. Xrm.WebApi calls are always Asynchronous, which is unusable in this case of adding dynamic filter using addCustomFilter.
You have to use XMLHttpRequest and make that call as Synchronous by setting third parameter as false like below:
var req = new XMLHttpRequest();
req.open("GET", Xrm.Utility.getGlobalContext().getClientUrl() +
"/api/data/v9.0/test_record1?$select=test_field1", false);

In order to work around the async delay, I think you're going to have to reorganise your code:
Add a form OnLoad event and execute the query to retrieve test_field1 and cache the results in a parameter
In the OnChange event, remove the presearch filter, re-execute the query to retrieve test_field1 and update the same parameter (from onload)
In testFunctionFilter use the cached results rather than building the presearch filter from scratch

Passing JavaScript select value between forms

I'm in need of some expert JavaScript advice. I'm coding using Electron.
The issue: I'm trying to capture the value selected from the second of two dropdown lists and pass it back into a JavaScript file. The code below is ordered as it would run. The dropdown code is not shown as it is simply populated by the viewProvinces function below. The first dropdown's id is "country-select" while the second is "province-select".
In this case, a link is clicked in Index.html which calls the anonymous function in Data.js. The anonymous function calls viewProvinces that populates the parray/data variables from the anonymous function which produces the alert showing the value returned.
(FYI) viewProvinces also populates the second dropdown (id province-select) by filtering based on the values produced in the first dropdown (id country-select). For example, if Afghanistan is selected as a country in the first, then only provinces from Afghanistan are shown in the second.
Moving on, viewProvinces calls Provinces which is an array populated when it calls getProvinces after querying a SQLite database for the source data.
ViewProvinces, Provinces, and getProvinces all work correctly. The link and the anonymous function are the issue and technically work in that they produce a result, but not the correct result. When the link is clicked it produces "object Object". I believe I understand why it is doing this, though I am not skilled enough (yet) to know how to fix it. I do not know how to adjust the code so that it returns the actual value(s) selected from the second (provinces) dropdown.
Put simply, the data is gathered from a SQL query that populates a series of arrays that further populates the dropdown list. The value of this list, once selected, should be returned back to the source JavaScript file into a variable (it fails here).
Apologies if this sounds convoluted, but I'm trying to be thorough. Any help in this matter would be greatly appreciated! Thank you!!
Index.html:
<a id="test-select" href="#">test</a>
Data.js:
$( "#test-select" ).click(function(e) {
e.preventDefault();
var parray = viewProvinces($("#country-select").val());
var data = $('#test-select').data(parray);
alert(data);
});
View.js:
function viewProvinces(ccode) {
var viewPro = Provinces(function(results) {
// Code only gets triggered when Provinces() calls return done(...);
var container = document.getElementById('province-select');
var fragment = document.createDocumentFragment();
results.filter(function(el) {
return el.ccode === ccode;
}).forEach(function(loc, index) {
var opt = document.createElement('option');
opt.textContent = loc.pname;
opt.value = loc.pcode;
fragment.appendChild(opt);
});
container.appendChild(fragment);
});
}
Model.js:
function Provinces(done) {
//Pull location values from data
return getProvinces(done);
}
Data.js:
function getProvinces(done) {
var sqlite3 = require('sqlite3').verbose();
var file = 'db/locations.sqlite3';
var db = new sqlite3.Database(file);
var stmt = 'SELECT Country.CountryId, Country.CountryCode, Country.CountryName, Province.ProvinceName, Province.ProvinceCode FROM Province INNER JOIN Country ON Province.CountryId = Country.CountryId'
var larray = [];
db.all(stmt, function(err, rows) {
// This code only gets called when the database returns with a response.
rows.forEach(function(row) {
larray.push({
ccode: row.CountryCode,
cname: row.CountryName,
pname: row.ProvinceName,
pcode: row.ProvinceCode
});
})
return done(larray);
});
db.close();
}

I have tried to answer your question via a fiddle based on your code created here but I had some trouble understanding a couple of things in your code, so I might have missed something. The main change I made was to make the Provinces(function(results) {.. function return the array of filtered provinces:
function viewProvinces(ccode) {
return Provinces(function(results) {
var provinces = [];
// Code only gets triggered when Provinces() calls return done(...);
var container = document.getElementById('province-select');
var fragment = document.createDocumentFragment();
results.filter(function(el) {
return el.ccode === ccode;
}).forEach(function(loc, index) {
var opt = document.createElement('option');
opt.textContent = loc.pname;
opt.value = loc.pcode;
fragment.appendChild(opt);
provinces.push(loc);
});
container.appendChild(fragment);
return provinces;
});
Once this is done, the parray is correctly setup:
var parray = viewProvinces($("#country-select").val());
However, I was confused when I read this code:
var data = $('#test-select').data(parray);
alert(data);
I assumed you were trying to save the provinces data in the link's store, so modified the code as follows to demo that it works:
$('#test-select').data({
provinces: parray
}); // Save the provinces array
var data = $('#test-select').data(); // Retrieve the provinces array
//Dump it on the console
$.each(data.provinces, function(index, province) {
console.log("Province[" + index + "].name: " + province.cname);
});

Using Google App Script to get values from sheets and display them in text box

So, Google recently updated Google App Script API and added lots of nice features, however, in the process, they also depreciated LOTS of API. I have been working on a Library Database user interface for the place I work on my college campus, and when I wanted to update my app to the new API, a lot of things broke, and I can't figure out how to make them work again.
What I am trying to do is get a value from a Google Sheets file, and simply put that value in a text box on the web app. Currently I cannot get that work work. In addition, I discovered something that was troublesome, and that is, the debugger seems to not be correct. I know, bold accusation. Let me try to show you.
Code.gs
function doGet(e) {
var html = HtmlService.createHtmlOutputFromFile('index')
.setSandboxMode(HtmlService.SandboxMode.IFRAME);
return html;
}
function searchBooks(searchItem, searchType){
var sI = searchItem;
Logger.log(sI);
var sT = searchType;
Logger.log(sT);
var sheets = SpreadsheetApp.getActiveSpreadsheet().getSheets();
var ss = sheets[0];
var itemDataRange = ss.getRangeByName("itemInformation");
var selectedItem = null; //the item that will be returned
//var selectedSearch = searchItem;
var titles = sheet.getRange("K2:K9507").getValues(); //get the titles of the items
var authors = sheet.getRange("J2:J9507").getValues(); //get the authors in the sheet
var barcodes = sheet.getRange("B2:B9507").getValues(); //get the barcodes in the sheet
var itemsArray = new Array();
if (sT == '')
{
return null;
}
else if (sT.value == 'Please select type...')
{
var test = "this works";
Logger.log(test);
return selectedItem;
}
else if(sT == 'Barcode')
{
var selectedBarcode = sI;
for(var i = 0; i < barcodes.length; i++) //search for the barcode
{
if(barcodes[i] == selectedBarcode)
{
selectedItem = titles[i];
break; //break immediately because barcodes are not duplicated
}
}
if(selectedItem != null)
{
return selectedItem;
}
else
{
selectedItem = "No book(s) found";
return selectedItem;
}
return selectedItem;
}
}
...
index.html
<script>
function bookSearch()
{
var searchItem = String(document.getElementById('searchItem').value.toLowerCase());
var searchType = String(document.getElementById('searchType').value.toLowerCase());
google.script.run.withSuccessHandler(bookFound).searchBooks(searchItem, searchType);
}
...
function bookFound(selectedItem)
{
document.getElementById("bookResultBox").innHTML = selectedItem;
alert(selectedItem);
}
</script>
When I test this code, and put a search value with the category "Barcodes" selected, I successfully get console logs of the data being brought into the function searchBooks, however the debug console says that the variables sI, sT, searchItems, and searchType are all undefined.
I've also been having trouble trying to figure out the proper API calls to use to search through the spreadsheet (when dealing with stuff like getRangeByName). I think there might be a slightly different way to do this since the big update. I may have had it working before I changed some of the code, although I started changing a lot of it when I was trying to figure out WHY nothing was displaying. When I saw at the "undefined" debug console logs, it scared me a bit. I can't tell if I'm messing up, or the API is messing up.
Any help is much appreciated in advance :)

There's probably an error in your code. It's probably coming from line:
var itemDataRange = ss.getRangeByName("itemInformation");
Your variable ss is not a spreadsheet class, it's a sheet class. You can't get a RangeByName of a sheet class. There is no getRangeByName() method of the Sheet class.
I'd change your code to this:
var ss = SpreadsheetApp.getActiveSpreadsheet();
var itemDataRange = ss.getRangeByName("itemInformation");
If you need to get the first sheet:
var theFirstSheet = ss.getSheets()[0];
