Trigger an 'onClick' via URL, but do not visit that URL

Trying to launch a click event of .register-btn a nav item when visiting a given URL, but not allow the browser to visit that URL.
So, home.com/memberlogin would remain on home.com ( or redirect to home.com if I must ), and proceed to activate the click of a button.
This is what I have so far, which redirects nowhere as that ended up taking longer than the click event, and it also was quite messy having to load the 404, then wait, then redirect, then wait, then wait for the click event.
I would like something clean and smooth if possible.
jQuery(document).ready(function() {
jQuery(function() {
switch (window.location.pathname) {
case '/memberlogin':
jQuery('.register-btn a').trigger( "click" );
return False;
}
});
});
Probably explained it dreadfully so apologies all - the .register-btn a already exists so I can't create this element, I simply wish to trigger the click for it when visiting a URL/link. Open to suggestions but I assumed something like /memberlogin would suffice, then the link would trigger. The snag is I don't want to "visit" that URL, but use it for the trigger only.
Open to an easier way and tell me if I am asking for something that doesn't work, just figured there must be a way.

Have you tried e.preventDefault() ?
click
and the jQuery:
$('.dontGo').on('click',function(e){
e.preventDefault();
//do stuff
})
fiddle: https://jsfiddle.net/b9x7x4m6/
docs: http://www.w3schools.com/jquery/event_preventdefault.asp

A full javascript solution is (snippet updated as asked):
window.onload = function () {
[].slice.call(document.querySelectorAll('.dontGo')).forEach(function(element, index) {
element.addEventListener('click', function(e) {
e.preventDefault();
alert(e.target.textContent);
}, false);
});
// in order to target a specific URL you may write code like in reported,
// assuming the result is only one element,
// otherwise you need to use the previous [].slice.call(documen.....:
document.querySelectorAll('.dontGo[href="linkedin.com"]')[0].addEventListener('click', function(e) {
e.preventDefault();
alert('Linkedin anchor: ' + e.target.textContent);
}, false);
};
stackoverflow <br/>
google <br/>
linkedin <br/>
twitter <br/>
The querySelector let you select elements in a lot of different ways:
if you need to select an anchor with a specific href value you can write:
document.querySelectorAll('.dontGo[href="linkedin.com"]')
Remember, always, that the result of querySelectorAll is a NodeList array. You can test against the length of such array in order to get, just for instance, only the second element if it exists, like:
var nodEles = document.querySelectorAll('.dontGo[href="linkedin.com"]');
if (nodEles.length > 1) {
nodEles[1]......
}
or you can use the format:
[].slice.call(...).forEach(....
to convert the NodeList to a normal array and than apply the event listener for each element.
Yes, you may prefix the href attribute of anchor tag with an hash (#) to avoid page redirecting. But, in this case, the hash tag is used to jump in another page section and this will change your url.

Simply create a function
function theAction(){
return false;
}
Then your link will be
page name

jquery file tree highlight selected

I am implementing a jQueryFileTree (http://www.abeautifulsite.net/jquery-file-tree/) as a file browser and would like each file or directory the user clicks on to stay highlighted. I know this can be done using simple JavaScript or CSS, but I don't understand the source code well enough to know how or where to implement the highlighting. Can anyone point me in the right direction?

Well, you can capture a click using the click handler and add a class using addClass.
$('.thing-i-will-click-on').click(function() {
$(this).addClass('selected');
});
You can also remove a class using a similar method.
$('.selected').removeClass('selected');
Combining these two things should give you the desired result.

So after a little tinkering I got it to work!
First you have to go into the jqueryFileTree.js and modify line 80 from this:
h($(this).attr('rel'));
to:
h($(this));
This will return the object that is clicked on instead of the file name. To get the file name within the function(file) within the definition of the .fileTree you'll have to use:
file.attr('rel');
Now you have the object and you can use this in the function(file) to highlight you code. (selected is a CSS class I created that changes the background color)
$(".selected").removeClass('selected');
file.addClass('selected');

$('#your_filelist_id').fileTree({
root: '/',
script: '/connectors/jqueryFileTree.php'
}, function(file) {
var flist = $('#your_filelist_id a[rel="' + file + '"]');
if(flist.hasClass('selected')) {
flist.removeClass('selected');
}
else {
flist.addClass('selected');
}
});

How to set ButtonState Loading in HTML5 CSHTML Page

Here is my HTML entry that fires the GenerateBill() Javascript at the moment :
<a class="btn btn-primary" id="loading-example-btn" data-loading-text="Loading..." onclick="GenerateBill()">Generate Bill</a>
Here is the GenerateBill() method, this all works fine, all I want to do is add the button state feedback
function GenerateBill() {
var url = '/PremiseProvider/GenerateBill';
var data = {
StartDate: $('#from').val(),
EndDate: $('#to').val(),
premiseProviderId: $('#PremiseProviderId').val()
};
$("body").load(url, data);
};
Here is a code snippet from the Bootstrap 3 official Site on how to implement the button state feedback:
<script>
$('#loading-example-btn').click(function () {
var btn = $(this)
btn.button('loading')
$.ajax(...).always(function () {
btn.button('reset')
});
});
</script>
My Question is how can I implement in my GenerateBill script, the bootstrap example uses an Ajax call, can I make it work without making too many changes to what I have?

If I might make a few suggestions that will both fix your issue and improve your code.
Instead of using an onclick event, add an event listener in your javascript, and call the function from there.
Add the .button('loading') call to that same event listener.
Don't leave off the href for an <a> tag. It will cause some browsers to not show the pointer correctly on hover.
Your link will look as follows:
Generate Bill
Leaving your GenerateBill() logic alone, the listener you need to add to your javascript:
$('#loading-example-btn').click(function () {
$(this).button('loading');
GenerateBill();
});
A working example of this code (with GenerateBill() simplified) is available here: http://www.bootply.com/VTSNA1XMcm

Clicking a link programmatically after using preventDefault()?

I'm trying to change a href link programmatically (according to a result from an ajax async operation) and open it in a new window (I don't want to use window.open as it behaves like a popup and being blocked in IE).
The following code works only after clicking MANUALLY on the link for a second time, how can I make it work on the first click?
Simplified example:
trying to change href link dynamically
<script type="text/javascript">
document.getElementById('link').addEventListener("click", function (e) {
if (!e.target.hasAttribute("target")) //only preventDefault for the first time..
{
e.target.setAttribute("target", "_blank");
e.preventDefault();
updateLink();
}
});
function updateLink() {
// --HERE I PERFORM AN AJAX CALL WHICH TAKES A WHILE AND BY ITS RESULT I DECIDE WHICH URL TO USE - BUT HERE I JUST USE IT HARDCODED--
document.getElementById('link').setAttribute("href", "http://google.com");
document.getElementById('link').click();
}

I organized your code in this jsFiddle: http://jsfiddle.net/mswieboda/Hhj4D/
The JavaScript:
var $link = document.getElementById('link');
$link.addEventListener("click", function (e) {
if (!e.target.hasAttribute("target")) {
//only preventDefault for the first time..
e.target.setAttribute("target", "_blank");
e.preventDefault();
updateLink();
}
});
function updateLink() {
$link.setAttribute("href", "http://google.com");
$link.click();
}
This worked for me when I ran it. Hovering the link, you could see http://demo.com but clicking it takes you to http://google.com. Is this the desired functionality? You can definitely use the updateLink function any time (after an AJAX call) to change the href, also, you could probably set the _target in that function as well, makes more sense to me that way.

Javascript - how do I minimise this code example?

a quick question.
At the moment I have 12 links on a page, and 12 corresponding javascript codes that run when a each button is clicked.
I know 100% there must be a method of having 1 javascript code and the link passing a variable to it, so I don't have to have 12 different codes.
EG. Here is a link I'm currently using:
Anatomical Pathology
And the Javascript function that is run when the link is clicked loads some html from a php script into a div which is previously defined as level2:
$('#button1').click(function() {
level2.load("http://hello/script.php?url=poodles");
});
What I'd really like to do is something like this with the link:
Anatomical Pathology
And the function something like this, so I only need the 1 function not 12:
$('#button1').click(function() {
level2.load("http://hello/script.php?url=' + passurl + '");
});
How do I go about getting the data from the link tag into javascript, and also how do I add this passed variable into the url I want the javascript to pull data in from?

passurl isn't standard attribute, you should use data-passurl
$('#button1').click(function() {
var passurl = $(this).data('passurl'); // or $(this).attr('data-passurl');
level2.load("http://hello/script.php?url=" + passurl);
});

Why don't you utilize your hash there...
Anatomical Pathology
In your script
$(".button").each(function() {
// get the hash and extract the part we want store it in this enclosure
var url = $(this).attr("href").replace(/^#\//, "");
// create a click handler that loads the url
$(this).click(function() {
level2.load("http://hello/script.php?url=" + url);
});
});
This also brings about the possibility to extrapolate from that so that a hash passed through the url can also operate the script loading...

You can use the rel attributte (or any data- attributes if your using HTML5 Doctype) to save your URL and add a class to the links you want to execute your callback.
Anatomical Pathology
Your Callback:
$('a.button').click(function() {
level2.load("http://hello/script.php?url=' + $(this).attr('rel') + '");
});

For a more extensible solution you could consider making a json structure for your urls:
var urls = [{
"poodle":{
"url":"http://hello/script.php?url=poodle",
"someOtherData":"data"
},
"otherDog":{
"url":"http://hello/script.php?url=otherDog",
"someOtherData":"data"
}
}];
You would store some sort of key somewhere in your HTML element:
Anatomical Pathology
Then you would leverage this data structure in your functional code:
$('a').click(function () {
var key = $(this).attr('rel');
level2.load(urls[key].url);
});

As per Stuie, add a class to the links so that you can target them all at once. However, I don't see the need to fool with the hash, and I wouldn't add a bunch of click events either. Just delegate once and you're done:
<div id="wrapper">
Poodles
Schnausers
</div>
and the JS:
$('#wrapper').delegate('a.button', 'click', function(e) {
e.preventDefault();
var passurl = $(this).attr("href");
level2.load("http://hello/script.php?url=" + passurl); // assuming "level2" is valid from elsewhere
});
Where I have "#wrapper" you would designate any unique selector that is an ancestor of all your links. It's an element that listens for clicks on the a.button elements within.
