I want to be able to toggle a javascript function that opens a certain tab on my page when the page loads. However I only want this function to run automatically when coming from another page.
For example:
Page A has the function that opens said tab, which is triggered when clicking on a button normally.
I want the user to click a button on page B and redirect to page A, where the function on page A automatically triggers.
However if the user reaches page A from anywhere but page B I do not want this function to trigger automatically.
This is the best way I can describe it, any help would be great. (I should also mention this is being done is ASP.NET MVC4)
You can use document.referrer. Something like this.
if (document.referrer === 'pageB') {
// trigger the function
}

My website has button A. When I click it a pop up div appears with yes no option. I must click yes. So I write a script so that when I click button A, the yes option is automatically clicked. It goes like this
buttonA.onclick = function(){
document.getElementById('buttonYes').click()
};
I load this into Tampermonkey. When the page loads, the code work for the first time. After that the button goes back to their original behavior. The Javascript somehome only works once when the page is newly loaded. Can someone suggest a way to make the code works all the time in the page and I don't need to reload the page for it to work.
In my site I have many href and button that relocate the page you are in. I thought that, since you can't modify the body of the alert created with onbeforeunload, I can make my own type but my questions are:
Can I intercept when the page is relocated inside my site without onBeforeUnload or onUnload?
Can I make a function wait until a button i pressed?
Is it possible to intercept some other changes of the browser page like if the user try to close it?
Is it possible to disable the entire page and leave only a toast be available?
I'm trying to call a JavaScript function from an ASP.NET MVC view (.html) using Action Link/Hyperlink()/Link Buttons. Left click works good, but right clicking the link and choosing 'Open a New Tab or Page' is not working.
My attempt so far has been:
<a href="#" onclick=aFunction()>link</a>
aFunction(object)
{
alert('Inside Javascript Function')
}
Use the approach mentioned in this answer: How to run function on new tab from main tab? (Google Chrome)
Basically you would store the function in local storage and on page load event of the page this links open, you would check if there is a function stored in the local storage, and if so, then execute it.
This answer might help.
Try giving your hyperlink an id attribute (say, id="foo"), and create a click handler that performs a specified action whenever a#foo is right-clicked:
document.getElementById("foo").onmousedown = function(event) {
if (event.which == 3) {
alert('Inside Javascript Function');
}
}
EDIT:
Per your comment:
I don't want to execute the function as soon as the user right click. I want execute the function after the user right click the link and click open new tab option.
I don't believe this is possible (unless there is some arcane Chrome JavaScript API that detects such an event). It wouldn't make sense for JavaScript to know how Chrome works. Further, JavaScript is sandboxed in such a way that it doesn't have access to the user's local file system - by extension, it should not know what the Google Chrome process itself is doing.
I'm building a site using bootstrap and have created a navbar with some links. The index page consists of the navbar and a body with a single div that pulls in content (pages I've created) via jQuery's ajax feature (depending on what link was clicked in the navbar, that page is displayed in the div).
The site is for users who have permission to access pages based on folder settings I've created (if a user has access to a folder, he can view the pages within it). It works fine for the most part, but when a user who does not have access to a page clicks on a link, I assumed that the error page would show up in the div. However, it just bounces the user off the site completely to an error page.
My solution is to use a jQuery unload event.
I placed this in a .js file:
$( window ).unload(function() {
alert( "Bye now!" );
});
But a popup now shows up when I click on any external link, when I close the browser, or when I refresh the page. I only want it to activate when a user clicks on a specific link (one with an id class). I want to let them know that they clicked on a link that they do not have access to, and if they do not stay on the page they will be forwarded to an error page. How would I go about doing this?
--Update--
Here is the JSFiddle Link to JSFiddle
So for example, all users have access to the page "technology", so when they click that link on the navbar it is fetched and displayed in the div id "result". However, only some users have access to the page "inspections"; for those who have access the page is fetched, for those without it redirects them from my page to an external error page. I want a warning to pop up so they know that they don't have access and if they follow the link they opened that they will end up on an error page.
--Update 2--
Using Mr. Genuis' code got it working, but I have one final question. I implemented the code and a pop up appears for users who don't have access to the link (exactly what I wanted to happen), but when they click the OK button or click the x button on the popup, they are still forwarded to the error page.
Is there anyway to disable that? I tried updating the unload function (that Mr. Genuis provided) with this code, and it works (it gives the user an option to stay on current page which prevents the error page from loading), but the pop up function also activates when a user tries to close the browser page. I just want it to trigger when the link is clicked.
Here is the code i used:
$(window).bind('beforeunload', function(){ return '>>>>>Before You Go<<<<<<<< \n Your custom message go here'; })
I am really not sure if your approach is right for the given problem.
About activating the window unload event conditionally,
move that unload event hookup inside the link click event, that way you hookup the window unload event only when needed. Not always!
Update:
Something like below. For illustration purpose only.
Warning: I feel there is a smell in this approach.
$(".link").click(function(){
if(true){//Your condition check goes here.
$( window ).unload(function() {
alert( "Bye now!" );
});
}
else{
window.location.href = "someurl";
}
});
Is it possible to integrate a javascript into a hyperlink? Or make it into some sort of batch script or whatnot, so when the page has loaded it calls the javascript which is a button on the page?
To explain it further:
We have this page:
http://work.acceptance.XXXX.com/XXXX_Raffle/Lists/Raffle/overview.aspx
The sharepoint page has a survey on it.
To get the "popup" window to show, so you can answer a question in the survey, you need to press a button which calls this script:
javascript:__doPostBack('ctl00$m$g_e999ab40_719f_42fb_bd61_d986f232bdd5$ctl01$ctl00$toolBarTbl$RptControls$ctl00$diidIONewItem','');
So, is it possible to somehow combine the page + the javascript, so all they have to do is press one link or alternatively, a hyperlink which goes to a file on a server which triggers all this, so they instantly get to the page + the javascript automatically pops so they dont have to press the button?
Keep in mind, when I say "hyperlink" I mean the kind of hyperlink you would see in an email. A simple link to a website or a server location.
I'm not very good at everything that has to do with programming and webdesign, but I do have access to the sharepoint, though I'd need serious guiding in how to add anything there other than simple webparts. It's SharePoint Server 2010.
Here is a picture of the button and what happens when you press it.

Add an onload event to the page to get it to show the popup:
<script type="text/javascript">
window.onload = showPopup();
function showPopup() {
__doPostBack('ctl00$m$g_e999ab40_719f_42fb_bd61_d986f232bdd5$ctl01$ctl00$toolBarTbl$RptControls$ctl00$diidIONewItem','');
}
</script>
This needs to go on the page that you're linking to so that the link takes you to this page which then fires this onload. Put it before the closing tag on the page.
No. You cannot construct a URL that will load a document and then call some JavaScript.
You would have to modify the page you are linking to so it runs the JS automatically. It could look at the URL and run that function conditionally though (e.g. if (location.hash === '#foo') { ... }.)
