I am trying to create a script that when a button is clicked it changes the class of a DIV and then reloads the content of that DIV.
So far I have created a script that successfully changes the class of the DIV.
document.addEventListener("DOMContentLoaded", function (event) {
jQuery("#button").click(function () {
document.getElementById("id").className = "newClass";
});
});
but I still need it to reload the content of the DIV with the new class. I have looked around for a solution and found the following code that I have tried to add:
$("#id").load(window.location.href + " #id");
But gives me the following error:
(index):470 Uncaught TypeError: $ is not a function
What am I doing wrong here?
In plain jQuery you would use:
jQuery(function($) { // DOM is now ready and jQuery's $ alias sandboxed
$("#button").on("click", function () {
$("#id")
.addClass("newClass")
.load(window.location.href + " #id");
});
});
but I'm not sure why would you use the same location.href - and how is that correlated to any "content refreshing".
Also, by doing the above you'll get yourself duplicated #id elements, one inside the other:
Initial state:
<div id="id">Test test test</div>
After clicking the "Button" one or more times:
<div id="id" class="newClass">
<div id="id">Test test test</div>
</div>
which is clearly not something you'd want.
At first you have to map jQuery to $ to use code like $("#id").load(window.location.href + " #id"); Otherwise you have to use jQuery("#id").load(window.location.href + " #id"), like you did in your example. This is done by:
jQuery(document).ready(function( $ ){
// your Code goes here
});
You also used plain JavaScript and jQuery for the same purpose. document.getElementById("id") is equal to $('#id').
There can be many classnames, so a function or attribute .className can't make a sense. There is a list of classnames, and you you can add /remove them per .addClass() / removeClass() in jQuery or .classList.add() / classList.remove() in plain javaScript.
jQuery(document).ready(function( $ ) {
$("#button").click(function () {
$("#id")
.addClass("newClass")
.load(window.location.href + " #id");
});
});
An load the content as Roko described.
