I am using a variable below.
var newInput = {
title: this.inputTitle.value,
entry: this.inputEntry.value
};
This is used by my i
Declare value attribute for input tag (i.e value= {this.state.name}
) and if you want to clear this input vale you have to use this.setState({name : ''})
PFB working code for your reference :
<script type="text/babel">
var StateComponent = React.createClass({
resetName : function(event){
this.setState({
name : ''
});
},
render : function(){
return (
<div>
<input type="text" value= {this.state.name}/>
<button onClick={this.resetName}>Reset</button>
</div>
)
}
});
ReactDOM.render(<StateComponent/>, document.getElementById('app'));
</script>
You can use input type="reset"
<form action="/action_page.php">
text: <input type="text" name="email" /><br />
<input type="reset" defaultValue="Reset" />
</form>
I have a similar solution to @Satheesh using React hooks:
State initialization:
const [enteredText, setEnteredText] = useState('');
Input tag:
<input type="text" value={enteredText} (event handler, classNames, etc.) />
Inside the event handler function, after updating the object with data from input form, call:
setEnteredText('');
Note: This is described as 'two-way binding'
Let me assume that you have done the 'this' binding of 'sendThru' function.
The below functions clears the input fields when the method is triggered.
sendThru() {
this.inputTitle.value = "";
this.inputEntry.value = "";
}
Refs can be written as inline function expression:
ref={el => this.inputTitle = el}
where el
refers to the component.
When refs are written like above, React sees a different function object each time so on every update, ref will be called with null immediately before it's called with the component instance.
Read more about it here.
I'm not really sure of the syntax {el => this.inputEntry = el}, but when clearing an input field you assign a ref like you mentioned.
<input type="text" ref="someName" />
Then in the onClick function after you've finished using the input value, just use...
this.refs.someName.value = '';
Edit
Actually the {el => this.inputEntry = el} is the same as this I believe. Maybe someone can correct me. The value for el must be getting passed in from somewhere, to act as the reference.
function (el) {
this.inputEntry = el;
}
On the event of onClick
this.state={
title:''
}
sendthru=()=>{
document.getElementByid('inputname').value = '';
this.setState({
title:''
})
}
<input type="text" id="inputname" className="form-control" ref={el => this.inputTitle = el} />
<button className="btn btn-info" onClick={this.sendthru}>Add</button>
