I'm hoping to use javascript within tampermonkey to scrape https://www.intellizoom.com/ so I can be alerted immediately when any new jobs come in for me to accept (jobs can disappear within seconds if not acted on immediately). Unfortunately my login eventually expires, and the website redirects to https://www.intellizoom.com/login.
I therefore want to use a tampermonkey script matching the login URL to automatically log back in when needed.
I'm struggling to get this to work. First of, it seems you have to focus any input fields before they correctly accept any input from javascript. That works for adding the username and password, but just using focus() on the login button fails.
My test script successfully logs in if, before the message "click!" appears in the console, I physically click anywhere in the website page. (Hence the 5 second setTimeout to give me time to physically click - for test purposes). The login button then turns blue, and the .click(); javascript function then successfully submits the login details.
But, I can't find any way to simulate the physical click using javascript, all attempts to use click() on elements or on co-ordinates just does nothing (with no error messages in the console). Adding focus() before click() doesn't help either.
Can anyone figure out how to submit the login details for this website via javascript?
setTimeout(function(){
document.getElementById("email").focus();
document.getElementById("email").value = "username#Domain.co.uk";
document.getElementById("password").focus();
document.getElementById("password").value = "password";
},500);
setTimeout(function(){
console.log("click!");
document.getElementsByClassName("button large primary is-rounded")[0].click();
},3000);
UPDATE: The solution was kindly provided by Markfila - this code works:
setTimeout(function(){
document.getElementById("email").value = "username#Domain.co.uk";
document.getElementById("password").value = "password";
let event = new Event("blur");
document.getElementById("email").dispatchEvent(event);
document.getElementById("password").dispatchEvent(event);
document.getElementsByClassName("button large primary is-rounded")[0].click();
},100);
I've raised a follow up here question (since I'm not supposed to ask follow questions directly in here).
I dont think you need the focus, there using some kind of third party library for the ui and its not triggering the event that sets the value attribute. After a bit of messing around it looks like the ui library is setting the value on the blur event.
If you add this after setting the value then the login button should enable and the click code you have should work
let event = new Event("blur");
document.getElementById("email").dispatchEvent(event);
document.getElementById("password").dispatchEvent(event);
It seems like the window isn't focused because if you click the window then it will login and clicking the window focuses it.
You could try using var win = window.open("https://www.intellizoom.com/login") then win.focus() to focus the window.
So the whole code would look like this:
var win = window.open("https://www.intellizoom.com/login");
win.focus();
setTimeout(function(){
document.getElementById("email").focus();
document.getElementById("email").value = "username#Domain.co.uk";
document.getElementById("password").focus();
document.getElementById("password").value = "password";
},500);
setTimeout(function(){
console.log("click!");
document.getElementsByClassName("button large primary is-rounded")[0].click();
},3000);
I am not 100% sure about this but by reading your post this is what it made me think.
I hope this helps!

I am developing a project where user gets a conformation page. I want user not to click back or close tab or reload.
Now either I need to disable the browser features or get back button,tab close event, or reload event to java script so that I could take the needed steps to prevent my data to get lost.
I have used this:
window.onbeforeunload = function()
{
return "Try This";
};
But this get called even when I click a button that redirects the page.
If you just want to have the alert, understanding that the user is ultimately in control and can bypass your alert, then do what you're doing but use a flag that disables it when you're navigating and don't want the alert. E.g.:
var warnWhenLeaving = true;
window.onbeforeunload = function() {
if (warnWhenLeaving) {
return "your message here";
}
};
then in a click handler on the link/button/whatever that moves the user on that you don't want this to pop up on:
warnWhenLeaving = false;
In a comment you asked:
can i know that what user has clicked when alert is generated with this function. That is can i know what user has clicked (leave this page/stay on page)
The answer is: Sort of, but not really; you're almost certainly better off not trying to.
But: If you see your onbeforeunload function run, then you know the user is leaving the page and the browser is likely to show them your message. The browsers I'm familiar with handle the popup like an alert: All JavaScript code on the page is blocked while the popup is there. So if you schedule a callback via setTimeout, you won't get the callback if they leave and you will if they stay:
window.onbeforeunload = function() {
if (warnWhenLeaving) {
setTimeout(function() {
display("You stayed, yay!");
}, 0);
return "No, don't go!";
}
};
Live Example
So in theory, if you get the callback, they stayed; if you see an unload event, they left. (Note that there are very few things you can do in an unload event.)
I've tried that on current Chrome, current Firefox, IE8, and IE11: It works on all of those. Whether it will work in the next release of any of them is anybody's guess. Whether it works reliably on mobile browsers is something you'd have to test, and again could change.
I'm trying to achive the following:
On page A we have an access restricted Link to page B. The access restriction is handled on the server side in PHP.
When a user clicks on this link to page B we display a modal dialogue on page A (via javascript) with a form, having the link's href (B) as the action. (To give the user an immediate feedback. The fallback is to redirect him to a login form that redirects him to the site he wants to access.)
This system works quite well.
But now comes my question:
We have access restricted links that should be opened in a new window.
Now if I use target="_blank" on the form the user stays logged out on the page he came from (A), that is still open in the background.
Is there a way to reload the page (A, in the background) right after the form has been submitted to the new window (B)?
My first idea was to use window.location.reload(); in the submit handler on page A.
This didn't work in chrome and from what I understand could create a race condition.
Another idea would be to log the user in via an ajax call and open a new window through javascript. Is there a way to do this without having to deal with pop-up blockers?
I implemented the idea of lostsource (see below) with one slight addition.
As I need to reload only once, the timer of setInterval can be stopped if the cookie changed.
var ri=setInterval(function() {
if(oldCookie != document.cookie) {
// assuming a login happened, reload page
clearInterval(ri);
window.location.reload();
}
},1000); // check every second
I still love the idea. stackoverflow is awsome!
Assuming you're storing PHP session information inside a cookie, you might be able to monitor your document.cookie for changes.
Before submitting the form store the value of the current cookie and monitor it for changes with a timer:
form.onsubmit = function() {
var oldCookie = document.cookie;
var cookiePoll = setInterval(function() {
if(oldCookie != document.cookie) {
// stop polling
clearInterval(cookiePoll);
// assuming a login happened, reload page
window.location.reload();
}
},1000); // check every second
}
On the parent page, do you have any visual/functional changes because of the login? As in any new actions possible?
If not, then you dont have to do anything as you would be checking for login on every action from the parent page, you can check for permissions along with that.
If there are changes or additional functionalities, you can call a javascript function in the parent, say reloadMe, using window.opener.reloadMe()
Why not just a simple setTimeout
setTimeout(function(){ location.reload(); }, 1000);
It is a bit hacky, but seems appropriate for your situation.
I have this javascript method that needs to run in the background
window.setInterval(function(){
validateCaseStatus();
}, 3000);
On the same page I have a button that asks the user if he wants to submit uploaded documents. But I noticed when the popUp msg(alert) is up the script on the page wont run.
Is there a way to keep the script running?
I use this method to check if the case status is changed and disable window.onbeforeunload.
My question is if theres a way I can keep the script above running even when a popUp alert is shown.
//cancels onbefore close popup when docs are submitted
function validateCaseStatus(){
caseStatus = sforce.apex.execute("IFAP_WebService","CheckCaseStatus", {!$caseId});
if (caseStatus == "Uploaded" || caseStatus == "Submitted")
{
submitted = true;
window.onbeforeunload = null;
validateCaseStatus = null;
}
}
Try using WebWorkers. It's a new html5 concept, and requires a bit more work, but they are very easy to understand and very helpful. See https://developer.mozilla.org/en-US/docs/DOM/Using_web_workers?redirectlocale=en-US&redirectslug=Using_web_workers http://ejohn.org/blog/web-workers/ and http://www.html5rocks.com/en/tutorials/workers/basics/
I realize this is likely a duplicate, but I've been googling/SOing for a day now and I can't find a satisfactory answer. If there is an answer already on SO, please send me there.
I have a client that insists on having an exit message popup confirming they want to exit the site, just like Gmail does. (I've already tried arguing against it. He is immovable, so no comments about how that is bad practice please.)
I've found this code:
<script>
window.onbeforeunload = function() {
return 'Are you sure you want to exit?';
}
<script>
But it runs no matter what I do - reloading the page, clicking on the nav, etc.
I just want the message to show up when the user closes the tab/browser. I suspect it's something simple I'm missing but I'm not a Javascript expert.
Any help would be greatly appreciated.
Thanks
EDIT
Here's what is working pretty good. Thanks to all!
var isLeavingSite = true;
//This would be called on each link/button click that navigates
$('a, input[type="submit"]').click(function(){
isLeavingSite = false;
});
window.onbeforeunload = function() {
if(isLeavingSite)
return 'Are you sure you want to exit?';
}
Though it could be a fair amount of work (depending on how your site is written), you could do something like this (pseudo-code):
var isLeavingSite = true;
//This would be called on each link/button click that navigates
function GlobalLinkHandler()
{
isLeavingSite = false;
}
window.onbeforeunload = function() {
if(isLeavingSite)
return 'Are you sure you want to exit?';
}
If you're using jQuery, you can use the code below to flip the isLeavingSite flag:
$('a, input[type="submit"]').click(function(){ isLeavingSite = false; });
What'll have to do is make use a variable that you set if any link is clicked on the site, then inside the onbeforeunload event check if that variable is set meaning they clicked a link or not set meaning they're closing the tab.
You can also use that variable to simple set the href of the link; that will allow you to then check what link they clicked on inside the onbeforeunload event and allow you to check if they're clicking on a link to go to another page on your site or clicking on an external link to another site.
If your using jQuery try this Confirm before exit
Is it possible to block users from closing the window using the exit button [X]? I am actually providing a close button in the page for the users to close the window.Basically what I'm trying to do is to force the users to fill the form and submit it. I don't want them to close the window till they have submitted it.
I really appreciate your comments, I'm not thinking of hosting on any commercial website. Its an internal thing, we are actually getting all the staff to participate in this survey we have designed....
I know its not the right way but I was wondering if there was a solution to the problem we have got here...
Take a look at onBeforeUnload.
It wont force someone to stay but it will prompt them asking them whether they really want to leave, which is probably the best cross browser solution you can manage. (Similar to this site if you attempt to leave mid-answer.)
<script language="JavaScript">
window.onbeforeunload = confirmExit;
function confirmExit() {
return "You have attempted to leave this page. Are you sure?";
}
</script>
Edit: Most browsers no longer allow a custom message for onbeforeunload.
See this bug report from the 18th of February, 2016.
onbeforeunload dialogs are used for two things on the Modern Web:
Preventing users from inadvertently losing data.
Scamming users.
In an attempt to restrict their use for the latter while not stopping the former, we are going to not display the string provided by the webpage. Instead, we are going to use a generic string.
Firefox already does this[...]
If you don't want to display popup for all event you can add conditions like
window.onbeforeunload = confirmExit;
function confirmExit() {
if (isAnyTaskInProgress) {
return "Some task is in progress. Are you sure, you want to close?";
}
}
This works fine for me
What will you do when a user hits ALT + F4 or closes it from Task Manager
Why don't you keep track if they did not complete it in a cookie or the DB and when they visit next time just bring the same screen back...:BTW..you haven't finished filling this form out..."
Of course if you were around before the dotcom bust you would remember porn storms, where if you closed 1 window 15 others would open..so yes there is code that will detect a window closing but if you hit ALT + F4 twice it will close the child and the parent (if it was a popup)
This will pop a dialog asking the user if he really wants to close or stay, with a message.
var message = "You have not filled out the form.";
window.onbeforeunload = function(event) {
var e = e || window.event;
if (e) {
e.returnValue = message;
}
return message;
};
You can then unset it before the form gets submitted or something else with
window.onbeforeunload = null;
Keep in mind that this is extremely annoying. If you are trying to force your users to fill out a form that they don't want to fill out, then you will fail: they will find a way to close the window and never come back to your mean website.
How about that?
function internalHandler(e) {
e.preventDefault(); // required in some browsers
e.returnValue = ""; // required in some browsers
return "Custom message to show to the user"; // only works in old browsers
}
if (window.addEventListener) {
window.addEventListener('beforeunload', internalHandler, true);
} else if (window.attachEvent) {
window.attachEvent('onbeforeunload', internalHandler);
}
If your sending out an internal survey that requires 100% participation from your company's employees, then a better route would be to just have the form keep track of the responders ID/Username/email etc. Every few days or so just send a nice little email reminder to those in your organization to complete the survey...you could probably even automate this.
It's poor practice to force the user to do something they don't necessarily want to do. You can't ever really prevent them from closing the browser.
You can achieve a similar effect, though, by making a div on your current web page to layer over top the rest of your controls so your form is the only thing accessible.
Well you can use the window.onclose event and return false in the event handler.
function closedWin() {
confirm("close ?");
return false; /* which will not allow to close the window */
}
if(window.addEventListener) {
window.addEventListener("close", closedWin, false);
}
window.onclose = closedWin;
Code was taken from this site.
In the other hand, if they force the closing (by using task manager or something in those lines) you cannot do anything about it.
