Answered 2017-Mar-07 at 05:04As the document from facebook:
In HTML, form elements such as , , and typically maintain their own state and update it based on user input. In React, mutable state is typically kept in the state property of components, and only updated with setState()
So, your code put the constant value to value
attribute, it's wrong, this value cannot be changed and you can type anything.
QUESTION
I came from angularjs background, with 2 way binding I don't have to worry much, just declare a submit function, I can get the changed or unchanged value.
I'm stuck with react now. My input is not editable.
...ANSWER
Answered 2017-Mar-07 at 03:29If you do not want to use Controlled Components then you can use Uncontrolled Components.
Specifically, you can use the defaultValue
prop instead of value
on your input
.
As to your second question, you will have to be more clear what you are asking or perhaps better to ask in a separate Q altogether.
QUESTION
class HelloWorldComponent extends React.Component {
constructor() {
super()
this.getInput = this.getInput.bind(this)
}
getInput() {
alert('focused');
}
render() {
return (
);
}
}
ReactDOM.render(
,
document.getElementById('react_example')
);
...ANSWER
Answered 2017-Jan-20 at 04:15You forgot to add the correct refference. use this.getInput instead of getInput.
