我正在通过文本字段保存一个值,单击按钮后,我想禁用该按钮,以使用户无法再次按下它。
我正在使用React.js来实现该应用程序。
<button type="button" className="btn btn-info round btn-glow px-2 float-right">Confirm</button>
答案 0 :(得分:1)
创建这样的状态
state = {
btnIsDisable: false
}
设置为按钮
<button disabled={this.state.btnIsDisable} type="button" className="btn btn-info round btn-glow px-2 float-right">Confirm</button>
在onClick处理程序中更改状态
this.setState({btnIsDisable:true});

您必须创建一个类组件,并将初始状态按钮的状态设置为true,然后在触发click函数时将其更改为false
// Initial state
this.state = {
buttonEnabled : true
};
// onClick function
onClick(event){
this.setState({buttonEnabled: false});
}
render() {
const { buttonEnabled } = this.state;
return (
<div>
<button onClick={this.onClick} disabled={buttonEnabled}>
Your content here
<button>
</div>
)
}

// declare some variable for holding your button's state
state = {
disabled: false
}
...
onConfirmButtonClick () => {
// set state.disabled as true
this.setState({ disabled: true })
}
render () {
return (
...
<button
disabled={this.state.disabled} // add disabled attribute to your button along with your state
type="button"
className="btn btn-info round btn-glow px-2 float-right"
>
Confirm
</button>
)
}

链接中的工作代码:https://codepen.io/stanlee94/pen/gNOLxb
class Button extends React.Component {
state = {
disabled: false,
pointerStyle: 'pointer'
}
handleClick = () => {
//Do your logic here
console.log('Record added');
this.setState({
disabled: true,
pointerStyle: 'no-drop'
});
}
render() {
return(
<button disabled={this.state.disabled} type="button" onClick={this.handleClick}
style={{ cursor: this.state.pointerStyle }}>Confirm</button>
);
}
}
单击后,它将添加无效的指针类型,以为用户提供良好的用户体验。
