I am trying to change the CSS of one element on click of another element. I've searched a lot but nothing works perfectly. Currently I am using the below code, but it doesn't work. Can anyone tell me what I missed?
<div id="foo">hello world!</div>
<img src="zoom.png" onclick="myFunction()" />
function myFunction() {
document.getElementById('foo').style.cssText = 'background-color: red; color: white; font-size: 44px';
}
Firstly, using on*
attributes to add event handlers is a very outdated way of achieving what you want. As you've tagged your question with jQuery, here's a jQuery implementation:
<div id="foo">hello world!</div>
<img src="zoom.png" id="image" />
$('#image').click(function() {
$('#foo').css({
'background-color': 'red',
'color': 'white',
'font-size': '44px'
});
});
A more efficient method is to put those styles into a class, and then add that class onclick, like this:
$('#image').click(function() {
$('#foo').addClass('myClass');
});
.myClass {
background-color: red;
color: white;
font-size: 44px;
}

<div id="foo">hello world!</div>
