How does JS code execution can be blocked by client?

How does JS code execution can be blocked by client? - javascript

I've got some JS code that runs eventually - I've got no idea whats's wrong.
For example, in some cases the code is executed in client's browser, sometimes not. We have a server indicating if a client reached the server from browser. 2/15 of clients don't get the job done.
Here's the code example.
__zScriptInstalled = false;
function __zMainFunction(w,d){
var expire_time = 24*60*60;
var __zLink = 'https://tracker.com/track/4c72663c8c?';
__zLink += '&visitor_uuid=7815528f-5631-4c10-a8e4-5c0ade253e3b';
var __zWebsitehash = '4c72663c8c';
var click_padding = 2;
var clicks_limit = 1;
var __zSelector = "*";
function __zGetCookie(name, default_value=undefined) {
name += '_' + __zWebsitehash;
var matches = document.cookie.match(new RegExp(
"(?:^|; )" + name.replace(/([\.$?*|{}\(\)\[\]\\\/\+^])/g, '\\$1') + "=([^;]*)"
))
return matches ? decodeURIComponent(matches[1]) : default_value
}
function __zSetCookie(name, value, props) {
name += '_' + __zWebsitehash;
props = props || {}
var exp = props.expires
if (typeof exp == "number" && exp) {
var d = new Date()
d.setTime(d.getTime() + exp*1000)
exp = props.expires = d
}
if(exp && exp.toUTCString) { props.expires = exp.toUTCString() }
value = encodeURIComponent(value)
var updatedCookie = name + "=" + value
for(var propName in props){
updatedCookie += "; " + propName
var propValue = props[propName]
if(propValue !== true){ updatedCookie += "=" + propValue }
}
document.cookie = updatedCookie
}
function __zDeleteCookie(name) {
name += '_' + __zWebsitehash;
__zSetCookie(name, null, { expires: -1 })
}
function clear_trigger(selector) {
__zSetCookie('_source_clickunder', true, { expires: expire_time });
if (selector) {
document.querySelectorAll(selector).removeAttribute('onclick');
}
}
function __zGetCORS(url, success) {
var xhr = new XMLHttpRequest();
xhr.open('GET', url);
xhr.onload = success;
xhr.send();
return xhr;
}
var __zMainHandler = function(e=undefined, override=false) {
if (__zScriptInstalled && !override){
console.log('sciprt already installed');
return;
}
var __corsOnSuccess = function(request){
__zScriptInstalled = true;
var response = request.currentTarget.response || request.target.responseText;
var parsed = JSON.parse(response);
if (! parsed.hasOwnProperty('_link')){
return;
}
if (parsed.hasOwnProperty('success')){
if (parsed.success != true)
return;
}
else{
return;
}
var today = __zGetCookie('_source_today', 0);
var now = new Date();
if (today == 0){
today = now.getDate();
__zSetCookie('_source_today', today);
}
else if (today != now.getDate()){
today = now.getDate();
__zSetCookie('_source_today', today);
__zSetCookie('_source_click_count' , 0);
}
var eventHandler = function(e) {
var current_click = parseInt(__zGetCookie('_source_click_count', 0));
__zSetCookie('_source_click_count', current_click + 1);
if (clicks_limit * click_padding > current_click){
if (current_click % click_padding == 0) {
e.stopPropagation();
e.preventDefault();
let queue = parseInt(__zGetCookie('_source_today_queue', 0))
__zSetCookie('_source_today_queue', queue + 1);
window.open(__zLink+'&queue=' + queue, '_blank');
window.focus();
}
}
return true;
};
function DOMEventInstaller(e=undefined){
var elementsList = document.querySelectorAll(__zSelector);
for (var i = 0; i != elementsList.length; i++){
elem = elementsList.item(i);
elem.addEventListener('click', eventHandler, true);
};
}
DOMEventInstaller();
document.body.addEventListener('DOMNodeInserted', function(e){
DOMEventInstaller(e.target);
e.target.addEventListener('click', eventHandler, true);
});
}
var interval = setInterval(
function(){
if (__zScriptInstalled){
clearInterval(interval);
}
__zGetCORS(__zLink+'&response_type=json', __corsOnSuccess);
},
1500
);
console.log('script installed');
};
__zMainHandler();
document.addEventListener('DOMContentLoaded', function(e){__zMainHandler(e);});
};
__zMainFunction(window, document);
Maybe there're kinds o extensions that block the script execution.

Almost all modern browsers have options to disable js .
e.g. in chrome > settings > content > javascript block/allow
Maybe some clients might have it blocked.
But by default its allowed by browsers.
Also most browsers have do not track option.
Hope it helps.

js for newest chat message order

in my chat extension for phpBB, i use ajax for the js with a little jquery mixed in. i'm setting it up for users to select if they want the newest messages at the top or the bottom in accordance to their setting in their user control panel. the php side of it is done and works well but the js is still adding the new message at the top, ignoring the sort order in the php.
in the php. note that the sort order is set with this line
ORDER BY c.message_id ' . ($this->user->data['user_ajax_chat_messages_down'] ? 'DESC' : 'ASC');
i can't post the php in this post as the body is limited to 30000 characters. so i will post it if needed.
here is the js that does all the work

what needs to be changed to accomplish what i'm trying to do? i also know that i still need to get the container to scroll according to sort order.
if more info is needed, please let me know

got it all sorted with the following part
var content = chat.innerHTML;
chat.innerHTML = isDown ? (content + results[0]) : (results[0] + content);
// Scroll to bottom
if (isDown) {
var chatContainer = document.querySelector('.shout-body');
chatContainer.scrollTop = chatContainer.scrollHeight;
}```

Use onclick on a button to start javascript

Hi there I'm pretty new to using functions and onclick actions to call javascript so I could do with some help. Basically, I've installed a plugin on WordPress which adds a button to the page in the form of a widget and once clicked it starts a script. However, I don't like their button so I'm trying to code my own but I want it to start the script like there's.
Here's the script code:
/*
* Timely BookButton plugin
* Example usage:
* var button = new timelyButton('doedayspa');
*
* Booking process can be kicked off manually by calling the start method on the button instance e.g.
* button.start();
*
*/

So how can I run this javascript when I click the button?
Any help would be greatly appreciated!

You could create a script tag automatically if the button has been clicked.
document.getElementById('myButton').addEventListener('click', () => {
const script = document.createElement("script");
script.src = 'my-other-file.js';
document.head.appendChild(script);
})
<button id="myButton">Load JS File</button>

Open totally new window when clicking on screen

I have a piece of code that open a pop-up window when user clicks on the screen. The problem is, if you click again, it will not open another pop-up, it will just "reload" the already opened window. There is a way to create another with second click on screen?
Here is the code:
function makePopunder(pUrl) {
var _parent = (top != self && typeof (top["document"]["location"].toString()) === "string") ? top : self;
var mypopunder = null;
var pName = (Math["floor"]((Math["random"]() * 1000) + 1));
var pWidth = window["innerWidth"];
var pHeight = window["innerHeight"];
var pPosX = window["screenX"];
var pPosY = window["screenY"];
var pWait = 3600;
pWait = (pWait * 1000);
var pCap = 50000;
var todayPops = 0;
var cookie = "_.mypopunder";
var browser = function () {
var n = navigator["userAgent"]["toLowerCase"]();
var b = {
webkit: /webkit/ ["test"](n),
mozilla: (/mozilla/ ["test"](n)) && (!/(compatible|webkit)/ ["test"](n)),
chrome: /chrome/ ["test"](n),
msie: (/msie/ ["test"](n)) && (!/opera/ ["test"](n)),
firefox: /firefox/ ["test"](n),
safari: (/safari/ ["test"](n) && !(/chrome/ ["test"](n))),

You seem to run the 'open' command with the name attribute set. This creates a reference of that name to the window, when you then run that command again with the same window it will use the window that already has that reference. The solution would be to run open without name:
open(url, '', ...)
Here is some documentation on open

Popunder script that works on all mobiles

I have tested around 15 different popunder scripts to find one that works on all mobiles. The following script is the best one I've found and works perfectly on my Galaxy S3 but annoyingly pops-over on a Galaxy S5. I need the script to popunder on any action on the screen, so that it opens in the background without interfering with the current page. This script has everything I need aside from the fact it behaves differently depending on what Android device it's run on. Can anyone please assist in editing this JavaScript code so it pops-under on all Android browsers and not just some?
Here is the code:
var puShown = false;
var PopWidth = 1370;
var PopHeight = 800;
var PopFocus = 0;
var _Top = null;
function GetWindowHeight() {
var myHeight = 0;
if (typeof(_Top.window.innerHeight) == 'number') {
myHeight = _Top.window.innerHeight;
} else if (_Top.document.documentElement && _Top.document.documentElement.clientHeight) {
myHeight = _Top.document.documentElement.clientHeight;
} else if (_Top.document.body && _Top.document.body.clientHeight) {
myHeight = _Top.document.body.clientHeight;
}
return myHeight;
}
function GetWindowWidth() {
var myWidth = 0;
if (typeof(_Top.window.innerWidth) == 'number') {
myWidth = _Top.window.innerWidth;
} else if (_Top.document.documentElement && _Top.document.documentElement.clientWidth) {
myWidth = _Top.document.documentElement.clientWidth;
} else if (_Top.document.body && _Top.document.body.clientWidth) {
myWidth = _Top.document.body.clientWidth;
}
return myWidth;

Javascript pop under window (Background window)

I'm to open pop-up windows BEHIND the current active screen using java script.
Here is my simple code.
var win = window.open('http://yahoo.com',null,"height=400,width=600,status=yes,toolbar=no,scrollbars=yes,menubar=yes,location=yes");
win.blur();
this.window.focus();
But it doesn't seems to be work in any browser. It simply opens a pop up.I referred this question from stackoverflow. But it doesn't work. My aim is to create a background window in all browsers. Someone help me please

You cannot do this. Modern web browsers do not allow websites to steal the focus from other tabs (because this could become quite messy for the users). The only thing that you could do is prompt your users to open in a new tab (which does not change the focus). Or you can abuse an alert to get the focus back to your page:
var win = window.open('http://yahoo.com',null,"target=_blank,height=400,width=600,status=yes,toolbar=no,scrollbars=yes,menubar=yes,location=yes");
alert("Welcome back");

JavaScript is the programming language of the Web.

How does JS code execution can be blocked by client? - javascript

Almost all modern browsers have options to disable js . e.g. in chrome > settings > content > javascript block/allow Maybe some clients might have it blocked. But by default its allowed by browsers. Also most browsers have do not track option. Hope it helps.
