I am new to Bootstrap and stuck with this problem. I have an input field and as soon as I enter just one digit, the function from onChange
is called, but I want it to be called when I push 'Enter when the whole number has been entered. The same problem for the validation function - it calls too soon.
var inputProcent = React.CreateElement(bootstrap.Input, {type: "text",
//bsStyle: this.validationInputFactor(),
placeholder: this.initialFactor,
className: "input-block-level",
onChange: this.handleInput,
block: true,
addonBefore: '%',
ref:'input',
hasFeedback: true
});
According to React Doc, you could listen to keyboard events, like onKeyPress
or onKeyUp
, not onChange
.
var Input = React.createClass({
render: function () {
return <input type="text" onKeyDown={this._handleKeyDown} />;
},
_handleKeyDown: function(e) {
if (e.key === 'Enter') {
console.log('do validate');
}
}
});
Here is the code using React.Component which does the same thing
class Input extends React.Component {
_handleKeyDown = (e) => {
if (e.key === 'Enter') {
console.log('do validate');
}
}
render() {
return <input type="text" onKeyDown={this._handleKeyDown} />
}
}
Here is the jsfiddle.
const Input = () => {
const handleKeyDown = (event) => {
if (event.key === 'Enter') {
console.log('do validate')
}
}
return <input type="text" onKeyDown={handleKeyDown} />
}
