I have say 3 spans as below :
<span class = "testVar1" onClick = "testFunction(Var1)">
<span class = "testVar2" onClick = "testFunction(Var2)">
<span class = "testVar3" onClick = "testFunction(Var3)">
testFunction(var){
here I assign class "on" to the span which calls this function
}
If span with class testVar1 calls this then it becomes
<span class = "testVar1 on" onClick = "testFunction(Var1)"></span>
My Css is as below
.test .on {
some CSS
}
Is there a way in CSS where I can use a variable and apply css to those span which is clicked? Like
.test[Var1 or Var2 or Var3] .on {
some CSS
}
I have achieved it by using multiple selectors manually like#
.testVar1 .on {
some CSS
}
.testVar2 .on {
some CSS
}
I have read the post Using regular expression in css? , it,s helpful but not answering my question.
In this post css is applied to all the element, but I want css to be applied only to the element which called the function. and so on.
Any help or pointers would be appreciated! Thanks!
You are making things too complicated. Just use the same CSS class on all of them, then add the click listener programmatically, not as an inline onlick listener:
document.querySelectorAll('span.test').forEach(
span =>
span.addEventListener('click', () => {
console.log(`you clicked ${span.innerText}`)
span.classList.toggle('on')
})
).test {
background: red;
color: white;
display: inline-block;
padding: 40px;
}
.test.on {
background: green;
}<span class="test">foo</span>
<span class="test">bar</span>
<span class="test">baz</span>If you insist on inline event listeners (you really shouldn't, it's widely considered bad practice), for this simple example it's probably even easier:
function foobar(span) {
console.log(`you clicked ${span.innerText}`)
span.classList.toggle('on')
}.test {
background: red;
color: white;
display: inline-block;
padding: 40px;
}
.test.on {
background: green;
}<span class="test" onclick="foobar(this)">foo</span>
<span class="test" onclick="foobar(this)">bar</span>
<span class="test" onclick="foobar(this)">baz</span>Collected from the Internet
