So I have a button that is a div class, lets call it "login-button-arrow". I want to set up a javascript method, so when this div gets clicked on, a little javascript box can pop up.
How do I go about doing this? I have tried something like this:
login-button-arrow.onclick{alert('xyz')}
but I guess it does not work like that.
// Cache your elements:
var $lba= document.getElementsByClassName('login-button-arrow');
// You nice function:
function myPopup() {
alert( "xyz" );
}
// Assign a click event handler to every element:
for(var i=0; i<$lba.length; i++) {
$lba[i].onclick = myPopup;
}
Also see: http://caniuse.com/getelementsbyclassname and eventually https://gist.github.com/eikes/2299607 if you need to support IE6 :)
A somewhat newer JS version of the above would be (lacks support in IE8):
var $lba= document.querySelectorAll('.login-button-arrow');
function myPopup() {
alert( "xyz" );
}
for(var i=0; i<$lba.length; i++) {
$lba[i].addEventListener("click", myPopup, false);
}
ES6 would look like: jsBin demo
function myPopup() {
alert( "xyz" );
}
const buttons = document.querySelectorAll('.login-button-arrow');
[...buttons].map( btn => btn.addEventListener("click", myPopup));
$('.login-button-arrow').on('click', function() { alert('xyz'); });
var login-button-arrows = document.getElementsByClassName('login-button-arrow');
login-button-arrows.forEach(function(obj){
obj.addEventListener('click', function(){
alert('xyz');
});
});
using Jquery :
$('#login-button-arrow').on('click', function(){ alert('xyz'); });
