How to set a custom href into a button when onClick?

I have a URL
http://localhost:8080/BIM/teacher/reports/section-exercise/assignment?x=1&y=2&z=3
I have 2 btns
I'm not sure how would I bind those 2 btn to the correct URL.
If the Remediation is clicked, I want to set the href to
http://localhost:8080/BIM/teacher/reports/section-exercise/remediation?x=1&y=2&z=3
The only different is the 4th segment, the rest stay the same.
Any helps / suggestions on them will be much appreciated !
I guess - I might have to :
grab the whole URL
re-construct the newURL, store it in a variable
bind that newURL to my btn.
I hope I'm in the right track for this.
Let me know if you guys, notice something.

Here you can change the URL to what ever you like.
I am using Replace fucntion to change the URL on the fly
var url='http://localhost:8080/BIM/teacher/reports/section-exercise/assignment?x=1&y=2&z=3'
$('button1').click(function() {
$(this).attr('href', url);
});
$('button2').click(function() {
$(this).attr('href', url.replace('assignment','remediation');
});

$(/*remediation button selector*/).click(function() {
$(/*assignment performance button selector*/).attr('href', 'http://localhost:8080/BIM/teacher/reports/section-exercise/remediation?x=1&y=2&z=3');
});
I'm not sure if you meant you want the Remediation button to change the href for the first button, or if you want them to just have different hrefs; if it's the latter, they can just have the different hrefs directly in the HTML, no JS needed.

Aminas answer is good, but in case the first URL isn't always the same I would recommend this function (using Regex) to change only the file name of an URL:
function changeFileName(strURL, strNewName) {
return strURL.replace(/[^\/?]*(?=\?|$)/, strNewName);
}
This (a) works no matter what the original file name was, and (b) won't cause problem if the path contains the file name.

How to remove a class via JavaScript (NOT jQuery) at Wordpress

I need your help at a problem of my Wordpress Webpage. My Wordpress-page is an Single-Page-App with 3 different boxes of content. The left and center boxes are static, the right one changes its content by clicking on links of the other boxes. I decided, to load all the content in the right box and show them with the CSS-command visibility. With a combination of pathJS and JS, i want the URL to change by clicking on the links. So far so good - all works fine, but i dont get managed via my JS-Function to remove the shown-class.
My script looks like this:
<script>
function showDetailContent(showid) {
//suche objekt right_id -> was du zeigen willst -> getelementbyid
alert("1");
var id = document.getElementsByClassName('shown');
alert("2");
id.classList.remove('shown');
alert("3");
document.getElementByID("right_" + showid).classList.add('shown');
alert("4");
}
//var c = document.getElementById('content'); -->do the function :)
Path.map("#/?p=<?php the_id();?>").to(function () {
showDetailContent(<?php the_id();?>);
});
Path.listen();
</script>
The alerts are just my way of "debugging". I think its not the best way to debugg, but i am very new in the world of prorgamming and this is kind of easy.
However, the first two alerts are shown, if i activate a link. So the (first) mistake is on the line
id.classList.remove('shown');
Normally, the right-box is hidden, so that only one content is load.
Do you understand my problem till here?
I would appreciate fast help!
Greetings, Yannic! :)

Look at this : http://snipplr.com/view/3561/ to know remove class pure javascript

getElementsByClassName gets multiple elements, try:
var id = document.getElementsByClassName('shown')[0];
Or iterate through them if you want to remove class from all elements with class shown;

jQuery Make a Link in Active Status

I am working on a HTML template, but I cannot touch the HTML code, I can only work on CSS and JS files. So I cannot in any way edit the HTML code.
What I am trying to achieve is to put some links in active status when jQuery or Javascript recognizes that the current page URL is the same one of the link I want to put in active status, without editing the HTML code.
Is there a way to do it? I tried in many ways but with no luck.
Here is the HTML code ( Remember I cannot edit it ).
<span class="Tag_Nav_Aux">
Create Account
|
Login
|
My Cart
</span>
The jQuery or Javascript code should work on different links, other than the ones I reported above, since the HTML changes when the user is logged in or logged out.
So the jQuery should point the class Tag_Nav_Aux and add the Active class to any a tag it will find that has the link the same of the current URL.

You can do something like this. Your file name from the URL
var filename = window.location.href.substr(window.location.href.lastIndexOf("/")+1);
After that get the anchor from the navigation and apply some class.
$("span.Tag_Nav_Aux a[href*="+filename+"]").addClass('active');
Here you have to write a CSS active class which will make that link to appear like an active link.

Try this script
jQuery(function($){
$('.Tag_Nav_Aux a').filter(function(){
return $(this).attr('href').toLowerCase() === window.location.pathname.toLowerCase();
}).addClass('active');
});
and create a CSS rule for
.Tag_Nav_Aux a.active{
// style you want the active link to have
}

$(document).ready(function() {
var url = window.location.href.toLowerCase();
$(".Tag_Nav_Aux a").each(function() {
var $this = $(this);
var href = $this.attr("href").toLowerCase();
if(url.indexOf(href) > -1) {
$this.addClass("active");
}
});
});​

I think you need to check the current page url and assign a class to the item like to active.
I usually do putting class="active" based on current URL match with help of server side code.
But if you dont want server code you can do with help of JavaScript
var currentPage=window.location.href;
if(currentPage=="")
{
//logic to find and add a Class for the proper anchor tag
}

How to use variable to display certain content?

When I click the href, I want to display the image and description from the target id. Can someone correct this code for me and show me how to do it right? Thank you very much!
HTML:
<div id="gallery"><img/></div>
Click me
jQuery code:
var datas={
"images":[{ "src":"gallery/panorak.jpg",
"title":"PANORAK",
"date":"28/10/2010 Web Design",
"description":"desc",
"id":"panorak",
},
{
"src":"gallery/kamoa.jpg",
"title":"kamoa",
"date":"28/10/2010 Web Design",
"description":"desc",
"id":"kamoa",
},
]};
$(document).ready(function(){
var gallery=$("#gallery")
//****I don't know how to display it right at this point
var list=$("<ul/>");
gallery.append(list);
datas.images.each(function(i,j){
list.prepend($("<li/>").$("<img/>").attr("src",datas.images[i].src).load(function(){ }));
});
});
Any help is greatly appreciated! Thank you very much!

I have made some changes to your code:
http://jsfiddle.net/T5r6D/
Have a look at my jsfiddle link for all updates.
You had some structure in flow issues and javascript error.
I am adding all image in array using normal for loop. once loop is done, i wrap images with <li> and adding the list to the stage.
Keep in mind that images will not be shown coz it is not on the jsfiddle server. Try it on your side.
UPDATE
http://jsfiddle.net/T5r6D/1/
So the new update does not hide the full container.
The anchor #tag [href] will be matched with the images title tag. So once clicked on a button it will hide the image that matches.

Try this:
$(document).ready(function(){
var gallery=$("#gallery")
//****I don't know how to display it right at this point
$('a').click(function(){
var list=$("<ul/>");
gallery.append(list);
$.each(datas.images, function(i,j){
var img = $("<img/>").attr("src",datas.images[i].src);
list.prepend($("<li/>").append(img));
});
});
});
If you want to trigger events when something is clicked, you can use click() function. And I fixed each() function part. Check this documentation. And I split some code to improve readability.

How to add jquery events to added classes?

I am trying to create an image gallery, I am using numbers instead of left/right arrows. At the moment, I am trying to get it working with only 2 image (i.g 2 numbers)
this is the html . the id page, is the highlighted number
<div class="grid_1 pagelink" id="page"><p>1</p></div>
<div class="grid_1 pagelink"><p>2</p></div>
the first time the page loads, the code below works. so when I click on link 2 the the code bellow runs fine. But then I want the same code to be triggered when I click back on the first link; but when I do that, the page refreshes by ignoring the code bellow:
$('.pagelink').live('click', function(e){
e.preventDefault();
var frame = $(this).text() - 1;
var frames = 240 * frame;
// $('#gal').animate({marginLeft:'500px'},'slow');
$('#gal').animate({marginLeft: "+="+frames+'px'},'slow');
$(this).attr('id', 'page').removeClass('pagelink');
$('#page').addClass('pagelink').removeAttr('id','page');
// $('#book').animate({ left: '50' });
})
I thought that the .live() would do that for me but it is not working.
I hope you could help
thank you

Previous, this is because you are removing the class of link "pagelink" which were used to map the clicked event.
Also, use another class instead of id(#page) to identify the #page link, id might be problem if its already assign to other link. like
$(this).removeClass('pagelink').addClass('page');
$('.page').addClass('pagelink').removeClass('page');

live should work fine. i think you have a bug in your code, and its probably here:
$(this).attr('id', 'page').removeClass('pagelink');
$('#page').addClass('pagelink').removeAttr('id','page');
what exactly are you trying to accomplish with this code?
when you click on page2, the you set the div's id to be page, but now you have 2 elements with an id of page, and when you select that id, you get the first one (ie page1), but you still remove the class pagelink from page2
in other words, the bug is that at some point you will have 2 elements with the same id (and ids must be unique btw) so when you select that id with $('#page') you always get the first one
