I know this is super simple, but I can't work it out (I'm a designer).
I want to simply populate the href attribute value of the <a> tag, with the value of the src attribute of the <img> tag. So the image links to itself basically.
the image src will be updated through a super simple CMS and I want the link to dynamically update, instead of the user having to update the URL also.
I tried something like this, but it didn't work.
<a rel="lightbox[job1]" href="()document.getElementById("gal1_img1").src">
<img id="gal1_img1" src="images/gallery/job1/image-1.jpg">`enter code here`
</a>
You cannot inline JavaScript inside attributes the way you have currently. You can add a script to the page to do this:
<a id="link" rel="lightbox[job1]" href="#">
<img id="gal1_img1" src="images/gallery/job1/image-1.jpg">`enter code here`
</a>
<script>
document.getElementById("link").href = document.getElementById("gal1_img1").src;
</script>
try this as your <a>'s href:
href="javascript:window.location=this.getElementsByTagName('img')[0].src;"
Assuming there's only ever one image inside these <a> tags, this should work for anyone who's NOT running with javascript disabled.
try this.
var att = $('#gal1_img1').attr('src');
$("a[rel*='lightbox[job1]']").attr('href',att);

I am trying to get the URL of a link in the source code. The challenge is that the URL is hidden behind a image, and thus only letting me fetch the image-url.
I've been trying to figure a way to solve this issue by using the new CSS selector in the trigger system and also made a DOM variable that should get the URL when the image is clicked. There can also be multiple downloads.
Here is an example of what I am trying to achieve:
<div>
<div class="download">
<a href="example.com/The-URL-I-Want-to-get-if-top-image-is-clicked.pdf" target="_blank">
<img src="some-download-image.png"/></a>
<div class="download">
<a href="example.com/Another-URL-I-Want-to-get-if-middle-image-is-clicked.pdf" target="_blank">
<img src="some-download-image.png"/></a>
<div class="download">
<a href="example.com/Last-URL-I-Want-to-get-if-bottom-image-is-clicked.pdf" target="_blank">
<img src="some-download-image.png"/></a>
</div>
</div>
There are much code above and below this snippet, but with the selector it should be fairly easy to get the information I want. Only that I don't.
If anyone have met this wall and solved it, I really would like to know how. :)
This is one possible solution. So as I understand it, you would like to grab the anchor element's href attribute when you click the "download" image.
A Custom Javascript variable would need to be created so that you can manipulate the click element object:
function(){
var ec = {{Click Element}};
var href = $(ec).closest('a').attr('href');
return href;
}
So you will need to do your due diligence and add in your error checking and stuff, but basically this should return to you the href, and then you will need to parse the string to extract the portion that you need.
I am having issues with my CMS - its seems it doesn't like having an <a> tag within an <a> tag as my Fancy Box 2 set up has.
To test I replaced:
<a class="fancybox" href="#popup">
with
<div class="fancybox" href="#popup">
This solved my original issue, but because its not legitimate mark up and breaks a lot of the other code.
Would anyone know a correct way to modified Fancy Box 2 to do this?
You can always bind fancybox to any element other than the <a> tag with a valid (HTML5) structure and functionality, using the special fancybox's data-* attributes like :
<div class="fancybox" data-fancybox-href="#popup">open fancybox</div>
See JSFIDDLE
Here is the code I have:
$('#link').attr("href",link)
$('#link').text(text)
How do I change the title of a link using jQuery? I'm correctly changing the url, but I can't edit the text, what am I doing wrong?
<a id="link" href="" target="_blank">text</a>
$('#link').attr("href",data[1].url)
$('#link').attr("title",data[1].title)
title
I'm tring to simply change 2 things:
url
title (as show above)
I'm able to change the link, but the title won't change. I'm selecting the wrong trhing. Therefor is there a way to list all attr available to me? Or are you able to help me change the text title above?
Either answer is acceptable.
<div id="highlight" class="topicHighlight hero1">
<h3 id="h3">hero_1_large_text</h3>
<p id="p"></p>
<span id="coverTextSpan">hero_1_small_text</span>
<a id="link" href="url" target="_blank">text</a>
</div>
use html function:
$('#link').html(text);
or , if you are talking about the title attribute:
$('#link').attr('title','some title');
I think you need to use the HTML() method to change the content of the anchor tag.
Here is the link to the documentation.
you can try this javascript only.
document.getElementById('link').innerHTML = "new title";
i think this will surly helpful to you..
Thanks.
If all these answers don't work for you then you should check:
What element are you selecting and see if it's the correct one
What variable are you assigning to the title(data[1].title)
I recommend using firebug in firefox or using the dev console in google chrome, anduse the console.log() function to log things so that you don't have to alert() them all the time.
How can you do something like this:
<a href="some javascript statement that isn't a function call;" >myLink</a>
And have the js in the href execute when the link is clicked.
Just put the JS code directly in there:
fsljk
Though, you should not be doing inline scripting. You should unobtrusively attach event handlers.
<a id="lol" href="/blah">fdsj</a>
<script>
document.getElementById('lol').onclick=function() {
/* code */
};
</script>
<a href="javascript:var hi = 3;" >myLink</a>
Now you can use hi anywhere to get 3.
You can write inline-code in the same way as
<a href="javascript:[code]">
This method is also available in other tags.
addition
if you want to Execution when something tag clicking, you can fix with onClick attribute
<a onClick="function()">
I know this question is old but I had a similar challenge dynamically modifying the href attribute that sends an email when the anchor tag is clicked.
The solution I came up with is this:
$('#mailLink,#loginMailLink,#sbMailLink').click(function () {
this.setAttribute('href', "mailto:" + sessionStorage.administrator_mail_address + "?subject=CACS GNS Portal - Comments or Request For Access&body=Hi");
});
<a id="loginMailLink" href= "#" style="color:blue">CACS GNS Site Admin.</a>
I hope that helps.
How would I retrieve the javascript call in the anchor tag below in JS or JQuery? Basically I want to get the code ("javascript:do_my_function('blah', 'string1', 1);") retrieved so I can execute it. This anchor is embedded several deep in some div tags as well.
<a onmouseout="swapImage('btn1','','http://img2.comp.com/img/buttons/btn_g.png',1)" onmousedown="swapImage('btn1','','http://img2.comp.com/img/buttons/btn_g_d.png',1)" onmouseover="swapImage('btn1','','http://img2.comp.com/img/buttons/btn_g_a.png',1)" href="javascript:do_my_function('blah', 'string1', 1);">
<img id="btn1" width="180" height="60" alt="" src="http://img2.comp.com/img/buttons/btn_ge.png"/>
</a>
To retrieve it just use:
var href = document.getElementById('btn1').parentNode.href;
That just finds the img by id, and grabs its parent, the a tag in question.
To call it, you can use:
window.location = href;
Or you could parse it and eval() it. All of this is highly unconventional by the way. Do you not have any further control over the code?
To do it with jQuery you can do
var jscript = $('#btn1').parent().attr('href');
eval(jscript);
This is not a recommended way to do things. Changing the html would be much better
