i am developing web application with react.
I want to dynamically set 'checked' property on checkbox.
It showed a proper screen that i wanted, but not working when i programmatically set 'checked' property.
So, i have searched about this.
some people recommended to use 'defaultChecked' property.
ant then i tried this. but failed.
It has not changed when i had given event that programmatically set checked property. It always showed defaultChecked value.
source code
render() {
list = {
resource: {[...], [...] },
...
}
return (
<ParameterContainer values={ list } />
);
}
class ParameterContainer extends React.Component {
constructor(props) {
super(props);
}
render() {
const { values } = this.props;
return (
<div className="parameter-table">
<div className="parameter-row-container">
<ul className="parameter-row title">
<li className="parameter parameter-1">valid</li>
<li className="parameter parameter-2">Key</li>
<li className="parameter parameter-3">Type</li>
<li className="parameter parameter-4">oid</li>
<li className="parameter parameter-5">rid</li>
<li className="parameter parameter-6">desc</li>
</ul>
{
values.resource.map((value, i) => {//one row
return (
<ParameterItem value={ value } index={ i } key={ i }/>
);
})
}
</div>
</div>
);
}
}
class ParameterItem extends React.Component {
constructor(props) {
super(props);
}
render() {
const { value, index } = this.props;
const items = [];
for (let o in value) {
if (o === "valid") {
continue;
}
items.push(value[o]);
}
return (
<ul className={`parameter-row parameter-row-${ index+1 }`}>
<li className="parameter parameter-1">
<input type="checkbox" defaultValue={ value.valid } checked={ value.valid } onChange={ this.toggle }/> //i tried to this.
<Checkbox isChecked={ value.valid } /> // and then tried this...
</li>
</ul>
);
}
toggle(e) {
$(e.target).prop("checked", e.target.checked ? 0 : 1);
}
}
class Checkbox extends React.Component {
constructor(props) {
super(props);
this.state = {
checked: !!this.props.isChecked
};
}
handleChange = (e) => {
const { target: { checked }} = e;
this.setState({ checked });
}
render() {
return (
<input type="checkbox" checked={ this.state.checked } onChange={ this.handleChange } />
);
}
}
