JSX
let MY = React.createClass({
sendMsg : function(e){
alert($(e.target).attr('data-id'));
//sendMsgButton = ??
},
render: function() {
return (
<button is class = "send_msg"
data-id = "10"
onClick = {
this.sendMsg
} >
Send Message
<span> INSIDE SPAN </span> <span className = "sendMsgIcon" > ICON </span> </button>
);
}
});
ReactDOM.render(
<MY />,
document.getElementById("container")
);
Whenever im clicking the button sendMsg
i want the button element inside sendMsg
function.
But whenever im clicking a span or child element of the button e.target
returns the span/child element instead of button itself ( i know that's what e.target does)
But how do i get the element which was clicked ?
In Jquery its possible using
$('.sendMsg').click(function(){
let sendMsgButton = $(this);
});
How do i get the exact element ?
You should use e.currentTarget
instead of e.target
Example:
sendMsg : function(e){
alert($(e.currentTarget).attr('data-id'));
//sendMsgButton = ??
}
Hope this helps!
Use react refs
so you can avoid using Jquery and DOM selectors.

let MY = React.createClass({
sendMsg : function(e){
alert(this.button.getAttribute('data-id'));
//sendMsgButton = ??
},
render: function() {
return (
<button is class = "send_msg"
data-id = "10"
ref={(button) => { this.button = button; }}
onClick = {
this.sendMsg
} >
Send Message
<span> INSIDE SPAN </span> <span className = "sendMsgIcon" > ICON </span> </button>
);
}
});
Unrelated to your question, but this is how I would do this to avoid using jQuery & reading data form DOM.
