Why will the colour of the active link not highlight blue? [duplicate]

I have an anchor tag that has a local href value, and a JavaScript function that uses the href value but directs it to a slightly different place than it would normally go. The tag looks like
<a onclick="return follow(this);" href="sec/IF00.html"></a>
and a JavaScript function that looks like
baseURL = 'http://www.someotherdomain.com/';
function follow(item) {
location.href = baseURL + item.href;
}
I would expect that item.href would just return a short string of "sec/IF00.html", but instead it returns the full href, "http://www.thecurrentdomain.com/sec/IF00.html". Is there a way that I can pull out just the short href as put in the anchor <a> tag? Or do I lose that by natural HTML behavior?
I suppose I could use a string manipulation to do this, but it gets tricky because my local page may actually be "http://www.thecurrentdomain.com/somedir/somepath/sec/IF00.html", and my href field may or may not have a subdirectory in it (for ex href="page.html" vs. href="sub/page.html"), so I cannot always just remove every thing before the last slash.
You may wonder why I am requesting this, and it is because it will just make the page a lot cleaner. If it is not possible to get just the short href (as put in the anchor <a> tag), then I could probably just insert an extra field into the tag, like link="sec/IF00.html", but again, that would be a little messier.

The below code gets the full path, where the anchor points:
document.getElementById("aaa").href; // http://example.com/sec/IF00.html
while the one below gets the value of the href attribute:
document.getElementById("aaa").getAttribute("href"); // sec/IF00.html

document.getElementById("link").getAttribute("href");
If you have more than one <a> tag, for example:
<ul>
<li>
</li>
<li>
</li>
<li>
</li>
</ul>
You can do it like this: document.getElementById("link")[0].getAttribute("href"); to access the first array of <a> tags, or depends on the condition you make.

This code works for me to get all links of the document
var links=document.getElementsByTagName('a'), hrefs = [];
for (var i = 0; i<links.length; i++)
{
hrefs.push(links[i].href);
}

In my case I had a href with a # and target.href was returning me the complete url. Target.hash did the work for me.
$(".test a").on('click', function(e) {
console.log(e.target.href); // logs https://www.test.com/#test
console.log(e.target.hash); // logs #test
});

The href property sets or returns the value of the href attribute of a link.
var hello = domains[i].getElementsByTagName('a')[0].getAttribute('href');
var url="https://www.google.com/";
console.log( url+hello);

document.getElementById("aaa").href; //for example: http://example.com/sec/IF00.html

Giving variables from html to python

I want to give variables from html to python using javascript.
On clicking navbar coded as:
aa.html
<a href="{{url_for('to_python')}}" id='aa'>hello</a>
Where to_python route goes to bb.html
I want to pass variable animal='dog' when clicking on aa.html href.
I tried using
$("#aa").attr("href", '?animal=dog')
But this does not go to bb.html.
The result is aa.html?animal=dog ( I want bb.html?animal=dog)
※Also I would like to know a way to pass variables on method POST using javascript. Any Ideas?
I tried using
$('#aa').on("click", function(){
$.post('/to_python', {animal:'dog'}, function(res){
.....something
}
But this code sometime work, but sometimes not. Do not know what is wrong.

If you want to change the URL using JavaScript, try something like
var $aa = $("#aa");
$aa.attr("href", $aa.attr("href").split("?")[0] + "?animal=dog");
That is, instead of replacing the href, grab everything before any parameters it might already have, then replace the parameters with what you want. For example,
<a href="hello"> would become <a href="hello?animal=dog">
<a href="hello?parameter=yes"> would become <a href="hello?animal=dog">
etc. If you need to retain other parameters, you'll need to do a little bit more:
var $aa = $("#aa");
var currentHref = $aa.attr("href");
$aa.attr("href", currentHref + (currentHref.indexOf("?") == -1 ? "?" : "&") + "animal=dog");
This way
<a href="hello"> would become <a href="hello?animal=dog">
<a href="hello?parameter=yes"> would become <a href="hello?parameter=yes&animal=dog">

Split website link into 2 href link?

On my website public: http://abv.mk/company.aspx?id=40056 , i want to split http://www.donholding.com.mk & http://www.webklinika.mk to be separate links (and separate clickable like two different links - hrefs).
But in my admin-panel for the field website i only have 1 field available, where i input 2 web site links splited with ","
So is it possible in the public asp-file "company.aspx", to edit the file and insert some Javascript code, so i split the link from 1 href to 2 hrefs ?
<span id="ctl00_ContentPlaceHolder1_lblComWeb"><a target="_blank" href="http://www.donholding.com.mk, www.webklinika.mk" title="">www.donholding.com.mk, www.webklinika.mk</a> | donholding#live.com</span>

I'm guessing you have one field in the DB which stores the URL. This should probably instead be its own table - company_url, which takes company_id (in thie case, 40056) and the URL. You should bring back a DataSet, and create a HTML string to put in to the Literal (or whatever you're using).
That's the "you should do this" answer.
Now.. you could do...
$(document).ready(function(){
var el = $('span[id$="lblComWeb"]');
var el_a = el.children('a');
links = el_a.html();
links = links.split(',');
el.html('');
$.each(links,function(l){
var e = ''+links[l]+'';
el.append((l > 0 ? ',' : '') + e);
});
});
as you're already using jQuery. However, it's cheap and dirty and nasty and yucky.
Just putting that snippet in to your company.aspx file (between some tags) should do the trick.

This page only allows you to display one website.
The href property of the a html tag only support reference to one address/page.
What you could do is put there the link to another page which is yours, and in this page you can put as many different links to anywhere you want and other information too. Maybe search for some URL shortener service which allows something like this.
Now, if you actually do have access to the source code and modify it, all you have to do is:
<span id="ctl00_ContentPlaceHolder1_lblComWeb">
<a target="_blank" href="http://www.donholding.com.mk" >www.donholding.com.mk</a>, <a target="_blank" href="www.webklinika.mk" >www.webklinika.mk</a> | donholding#live.com
</span>

replace content of div with another content

I've been building a list of links, all of which should change the content of a div to another specific content (about 4 lines of stuff: name, website, contact etc.) upon a click.
I found this code:
<script type="text/javascript">
function ReplaceContentInContainer(id,content) {
var container = document.getElementById(id);
container.innerHTML = content;
}
</script>
and used it in such a way:
<li class="pl11">
superlink')">Pomorskie</a>
</li>
And it doesn't work as I expected.
It changes hyperlinks text from 'Pomorskie' to 'superlink'.
The plain text works just fine but I need links.
here's the http://xn--pytyfundamentowe-jyc.pl/projektanci/kontakty-p/ (only two of them show anything)
But after trying all of your recomendations, I think I'd jump to different divs with #links, cause nothing worked with this :/
Thanks a lot for trying, and cheers :)

Just as a completely sideways look at this, I'd suggest avoiding the nesting weirdness / complexity, and reducing the problem down.
Setup the content in a hidden (ie. <div id="replacements">...</div>) Grab the innerHTML from the node you want, and be done with it.
Much easier to get replacement content from non-devs that way too, kinda works great if you're in a team.
// Probably better in a separate helpers.js file.
function replaceContentInContainer(target, source) {
document.getElementById(target).innerHTML = document.getElementById(source).innerHTML;
}
Control it with: (lose that href=javascript: and use onClick, better as an event handler, but for brevity I'll inline it as an onClick attribute here, and use a button.)
<button onClick="replaceContentInContainer('target', 'replace_target')">Replace it</button>
We have our target somewhere in the document.
<div id="target">My content will be replaced</div>
Then the replacement content sits hidden inside a replacements div.
<div id="replacements" style="display:none">
<span id="replace_target">superlink</span>
</div>
Here it is in JSBin
Improve the dynamic nature of this by using Handlebars or another nice JS templating library, but that's an exercise for the OP.
edit: Note, you should also name functions with a leading lowercase letter, and reserve the leading uppercase style for Class names e.g. var mySweetInstance = new MySpecialObject();

The quotes are mismatched! So when you click you are getting a JavaScript error.
The browser sees this string:
href="javascript:ReplaceContentInContainer('wojewodztwo', 'superlink')">Pomorskie<
as:
href="javascript:ReplaceContentInContainer('wojewodztwo', '<a href="
Chnage the " inside to #quot;
<li class="pl11">
Pomorskie
</li>
Example fiddle.
Also note, using the href tag for JavaScript is a BAD practice.

You've got a problem with nested quotes. Take a look in your DOM inspector to see what the HTML parser built from it! (in this demo, for example)
You either need to HTML-escape the quotes inside the attribute as " or ", or convert them to apostrophes and escape them inside the JS string with backslashes:
<a href="j[…]r('wojewodztwo', '<a href="http://address.com">superlink</a>')">…
<a href="j[…]r('wojewodztwo', '<a href=\'http://address.com\'>superlink</a>')">…
See working demos here and here.
Better, you should use a onclick attribute instead of a javascript-pseudo-url:
<a onclick="ReplaceContentInContainer('wojewodztwo', …)">Pomorskie</a>
or even a javascript-registered event handler:
<li class="pl11">
<a id="superlink">Pomorskie</a>
</li>
<script type="text/javascript">
function replaceContentInContainer(id,content) {
var container = document.getElementById(id);
container.innerHTML = content;
}
document.getElementBId("superlink").onclick = function(event) {
replaceContentInContainer('wojewodztwo', 'superlink');
event.prevenDefault();
};
</script>

JQuery Copy text & paste into textarea

I've created a javascript function that will take a hidden span, copy the text within that span and insert it into a single textarea tag on a website. I've written a function in JavaScript that does this (well, kinda, only after a few clicks), but I know there's a better way - any thoughts? The behavior is similar to a Retweet for twitter, but using sections of a post on a blog instead. Oh, and I'm also calling out to jquery in the header.
<script type="text/javascript">
function repost_submit(postID) {
$("#repost-" + postID).click(function(){
$("#cat_post_box").empty();
var str = $("span#repost_msg-" + postID).text();
$("#cat_post_box").text(str);
});
}
</script>

Based on the comment in your question, I am assuming you have something like this in your HTML:
copy post
And I am also assuming that because you are passing a post ID there can be more than one per page.
Part of the beauty of jQuery is that you can do really cool stuff to sets of elements without having to use inline Javascript events. These are considered a bad practice nowadays, as it is best to separate Javascript from your presentation code.
The proper way, then, would be to do something like this:
<a href="#" id='copy-5' class='copy_link'>copy post</a>
And then you can have many more that look similar:
<a href="#" id='copy-5' class='copy_link'>copy post</a>
<a href="#" id='copy-6' class='copy_link'>copy post</a>
<a href="#" id='copy-7' class='copy_link'>copy post</a>
Finally, you can write code with jQuery to do something like this:
$(function() { // wait for the DOM to be ready
$('a.copy_link').click(function() { // whenever a copy link is clicked...
var id = this.id.split('-').pop(); // get the id of the post
var str = $('#repost_msg-' + id); // span not required, since it is an ID lookup
$('#cat_post_box').val(str); // empty not required, and val() is the proper way to change the value of an input element (even textareas)
return false;
});
});
This is the best way to do it even if there is only one post in the page. Part of the problem with your code is that on the first click it BINDS the function, and in the subsequent clicks is when it finally gets called. You could go for a quick and dirty fix by changing that around to just be in document.ready.

$("#repost-" + postID).click(function(){
$("#cat_post_box").val(''); // Instead of empty() - because empty remove all children from a element.
$("#cat_post_box").text($("#repost_msg-" + postID).text());//span isn't required because you have and id. so the selector is as efficient as it can be.
});
And wrap everything in a $(document).ready(function(){ /Insert the code here/ }) so that it will bind to $("#repost-" + postID) button or link when the DOM is loaded.

I had a problem with Paolo's example when I clicked on the link the text that appeared in #cat_post_box was "object Object". Once I added ".text()" to the end of that statement I worked.
var str = $('#repost_msg-' + id).text();
Thanks for you example Paolo!
