I know very little about js so please be gentle.
I'm using the below code which was originally used to swap classes. I thought it would be as simple as changing .className
to .href
but I was wrong.
My problem is that it works once and then stops.
$(document).ready(function(){
$('#click').click(function () {
$('#url').each(function(){
var classes = ['/1','/2','/3','/4'];
this.href = classes[($.inArray(this.href, classes)+1)%classes.length];
});
});
});
EDIT: Here is the html I'm using:
<a id="url" href="/0">hello</a>
My goal is to switch /0 with /1 then /2 and so on with each onclick.
You can use .attr()
, set a varible to -1
. At click
event handler increment variable until variable reaches classes.length
, then reset variable to 0
, without utilizing Remainder
operator.
$(document).ready(function() { var classes = ['/1','/2','/3','/4']; var i = -1; var url = $("#url"); $('#click').click(function () { i = (++i < classes.length) ? i : 0; url.attr("href", classes[i]); console.log(url.attr("href")); }); });
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"> </script> <button id="click">click</button> <a id="url" href="/0">hello</a>
This fails because the protocol file://
or http://
is silently added the the href
value.
So change this:
$.inArray(this.href, classes)
to:
$.inArray(this.href.replace(/^.*?\/\//, ''), classes)
... which removes the protocol from the string before looking it up in your array.
