Hi,
I am new to js and might be a silly question. sorry for that as I started to learn JS.
I have made 2 scripts. 1 for autoclick buttons and another 1 for autoclick nextpage button.
How to merge both codes to one after one. also I need to set 5 seconds delay between both this scripts.
Script 1:
var buttons = document.getElementsByClassName('Polaris-Button');
for(var i = 0; i <= buttons.length; i++)
buttons[i].click();
Script 2:
var btn = document.getElementsByClassName('ant-pagination-next');
for(var s = 0; s <= btn.length; s++)
btn[s].click();
Thanks in advance.

Where there are multiple CSS selectors, in what order is the result list? (I know, I should experiment and find out!). But for the OP, I suspect this may not be the required solution, since he's wanting all the buttons of one class clicked before the other. Also, it doesn't include the 5 second delay he's after.
So: simply wrap the first block of code in a function ('ClickPolaris') and the second block in another function ('ClickPagination'). To run one, then the other, simply:
ClickPolaris();
ClickPagination();
To implement a five-second delay, you'll need a timer interval:
ClickPolaris();
setTimeout(function() {ClickPolaris();}, 5000);
Of course you can then refine it to use a single parameterised function, called twice with the different class names:
function ClickButtons(classname) {
var buttons = document.getElementsByClassName(classname);
for(var i = 0; i <= buttons.length; i++) {
buttons[i].click();
}
}
ClickButtons('Polaris-Button');
setTimeout(function() {ClickButtons('ant-pagination-next');}, 5000);and further simplify using Richard's suggested syntax:
function ClickButtons(classname) {
document.querySelectorAll(classname).forEach(btn => btn.click());
}
ClickButtons('.Polaris-Button');
setTimeout(function() {ClickButtons('.ant-pagination-next');}, 5000);Note that in this syntax you need to include the . to indicate you're selecting by class name.

The matching elements will be returned in document order:
The querySelectorAll() ... must return a NodeList containing all of the matching Element nodes within the subtrees of the context node, in document order.
So given:
<input id="btn1" type="submit" class="ant-pagination-next">
<button id="btn2" class="Polaris-Button"></button>
<button id="btn3" class="ant-pagination-next"></button>
<button id="btn4" class="Polaris-Button ant-pagination-next"></button> then querySelectorAll(".Polaris-Button, .ant-pagination-next") will return [btn1, btn2, btn3, btn4].

I feel I'm pretty close here. I have like 5 phone number inputs, and instead of adding a event attribute in the input element, I thought I would just use a class called phoneNumber and loop all the element to ad an event listener. I'm close, just missing the glue to pass on the element value to the phone number function I stole off the internet and tweaked a bit.
I've done this before in typescript. But I've been really deep in this PHP project I've been working on. I can see the value of using inspector in the event, but PHP Storm isn't suggesting anything for it.
On my for loop, must examples used the index type loop, but I wanted to be a little more ES6 with it. Not sure if it's a good idea or not.
document.addEventListener("DOMContentLoaded",() => {
const phoneInputs = document.getElementsByClassName('phoneNumber');
for (phoneInput of phoneInputs) {
phoneInput.addEventListener('keydown', (e) => {
console.log(e.id);
formatPhoneNumber(e.value)
});
}
});

After some more reading, some articles said that this will be available within addEventListener. So I'm just going with it, should work. I have to wait for my DEV server to become available again to test it.
document.addEventListener("DOMContentLoaded",() => {
const phoneInputs = document.getElementsByClassName('phoneNumber');
for (let phoneInput of phoneInputs) {
phoneInput.addEventListener('keydown', () => {
formatPhoneNumber12(this.value)
});
}
});

That didn't work at all. Fiddled with it for about 30 minutes on the DEV test server this time and came up with this that works for me in this format xxx-xxx-xxxx
document.addEventListener("DOMContentLoaded",() => {
const phoneInputs = document.getElementsByClassName('form-control phoneNumber');
for (let phoneInput of phoneInputs) {
phoneInput.addEventListener('keydown', event => {
event.target.value = formatPhoneNumber12(event.target.value);
});
}
});
function formatPhoneNumber12(value) {
if (!value) return value;
const phoneNumber = value.replace(/[^\d]/g, "");
const phoneNumberLength = phoneNumber.length;
if (phoneNumberLength < 4) return phoneNumber;
if (phoneNumberLength < 7) {
return `${phoneNumber.slice(0, 3)}-${phoneNumber.slice(3)}`;
}
return `${phoneNumber.slice(0, 3)}-${phoneNumber.slice(
3,
6
)}-${phoneNumber.slice(6, 9)}`;
}

NB: This will only add the event handler to matching elements which exist at the point when your code is run. If you modify the document at any point to add new matching elements, they will not have the event handler attached.
You would probably be better off using event delegation[^]. Since you'd only have a single event handler, it can even be more efficient.
document.addEventListener("keydown", (e) => {
const el = e.target;
if (el.classList.contains("phoneNumber")) {
console.debug(el.id, el.value);
el.value = formatPhoneNumber(el.value);
}
});

I wasn't thinking of that situation when I composed it. It's a customer form, with their home, office, cell phone numbers. I just needed to make sure that the user followed the format of xxx-xxx-xxxx.
So your saying that I don't have to wait until the Dom is loaded to add the keypress event?
I just thought it was the right thing to do. I'll give it a try.

Right now the company, only has offices in California, a single state. So I did add all 50 states at least. And I did use type="tel" as well, standard procedure for me over the last 3 years. My options are limited on this project, because I'm using the existing database created in 2003. This project is a reimagination of code , or the existing project to bring it up to PHP 8 and modern browsers in 2021.
I just tried your suggestion, and I don't have to wait for the DOM to load before adding the listeners. I also thought I had to iterate the HTML Collection to hit each phone input, which is not the case. That's pretty slick Richard.

I just read the link reference, and now I get what your suggesting. What a radical concept! I guess I was on the right track by changing my design to not use an element attr for the event. But I was still thinking on a individual element level, and not a unlimited collection as a whole. Too bad the customer won't appreciate it.

I suspect your global cache of NPM modules is on your old machine, and didn't copy over to your new machine. Rebuilding this is tough to do and requires reading up. There is no exact fix. Same thing happen to me, and I had to rebuild my package.json and global cache.

IMO, that's j Query and nobody uses that anymore. It was replaced with vanilla JavaScript about 6 years ago. It looks like your mixing Javascript with jQuery. I haven't written a line of jQuery in 4 years now, and can't remember it anymore.

How to deskew a page of pdf document which is loaded through pdf.js
|
|

|

I need a Wrapper or a Class that can control the Max Length of an Array on setting a value... It might be possible with a Prototype too, which is fine...
let myArray = new ArrayClassThing();
myArray.setMax = 50;
myArray[50] = "Foo";
myArray[51] = "Bar";
Javascript is different than Ruby where you can use special characters to define Getter and Setter methods:
class Array_Wrapper
def initialize
@data = []
end
def [](id)
if id <= 50 and @data[id]
return @data[id]
end
end
def []=(id,value)
if id <= 50
@data[id] = value
end
end
As far as I understand, cant use a "[]" as a Getter or Setter Method, and I need something that can do exactly that, just to control a Static Maximum, like in the first code block... Perhaps a better question to ask is how to define Getter and Setter Method WITHOUT A PROXY (which I KNOW is damn well good and possible) of a Class Prototype, but from inside the constructor (which I also know is syntactical sugar)...
Can anyone help out with this?

Braces have multiple uses in JavaScript. In this case, they denote a new block:
block - JavaScript | MDN[^]
The code demonstrates the scoping rules which apply to variables declared with the let keyword:
let - JavaScript | MDN[^]

I have some difficulties with a multiple select (ID:VALUE).
My Goal is to make a multiselect pulldown (like gender-sample) with the difference that i want to see only the text not the value's (value's are my Database ID's).
First off all I am pretty new with the tabulator library and still learning
Now I wrote some code witch works fine when you place only one id in a dataset-row, with multiply id's the view looks good but when you open this select for the firsttime ID's are placed as text in cell and there are no options selected in the pulldown. When you select some everything works like I want.
I'll think i am missing some intitalize code? Or do I need a customeditor too?
This is my code:
{
title: "City",
field: "citycode",
editor: "select",
editorParams:
{
multiselect:true,
values: city
},
cellClick:function(e, cell)
{
},
formatter: function(cell, formatterParams, onRendered)
{
var row = cell.getRow();
var rowIndex = row.getIndex();
sel = document.createElement('select');
sel.style.width = '100%';
sel.style.color = 'lime';
sel.style.height = '40px';
sel.style.position = "relative";
sel.style.border = 'none';
sel.style.background = 'inherit';
var cellContent = '';
if (cell.getValue() !== undefined) {
var cellStr = cell.getValue().toString();
var cityArr = cellStr.split(",");
var i;
for (i = 0; i < cityArr.length; i++) {
if (i > 0) cellContent += ',';
cellContent += city[cityArr[i]];
}
}
sel.innerHTML = '' + cellContent + ''; // Show the text in UI instead of Value.
var mess = document.getElementById("message"); //refer to the div tag
mess.innerHTML = cell.getValue(); //set text in the div tag
return sel;
}
},

I created a web API made with node express and MSSQL database. When I request to the API at first time, it's response time is about 2000ms. But after that, it works less then 200ms. The problem only happens when I first time call the API, or after idle for minutes.
I tried to access from multi devices. The problem seems happens on every 'first time' request of each device.
