Say I have the following React element (example fiddle here):
var Hello = React.createClass({
getInitialState: function() {
return {parsed: false};
},
_parseEvent: function(event) {
var parser1 = event.currentTarget.selectedOptions[0].value;
var parser2 = event.target.value;
var parser3 = event.nativeEvent.srcElement.value;
if (parser1 && parser2 && parser3)
this.setState({parsed: true});
},
render: function() {
var parsing = "parsing worked";
return (
<div>
<select
onChange={this._parseEvent}>
<option value="----">----</option>
<option value="Yes">Yes</option>
<option value="No">No</option>
</select>
<p>
{ this.state.parsed ?
{parsing}
: null}
</p>
</div>
);
}
});
React.render(<Hello name="World" />, document.getElementById('container'));
I'm using three ways of parsing the value of the <select>
element. The first does not work on IE 10, and I know it's a bug per my question here. However, of the other two ways, parser2
or parser3
, which is the proper way to get the value of a <select>
element in React? Why? Thanks for any help!
Use what you would use in a W3C compatible browser:
This is also agnostic to the type of the form control element.
