我正在向测验API提出get
请求。当用户得到正确的答案时,会显示下一个答案。
这一切都运行良好,但是当用户得到正确的答案时,我在尝试清除输入框时遇到了一些麻烦。 I read this earlier并且据我所知,它应遵循相同的逻辑。
有人能发现这里的错误吗?
var Quiz = React.createClass({
getInitialState: function() {
return {
question: '',
answer: '',
value: '',
score: 0
}
},
getData: function() {
$.get('http://jservice.io/api/random', function(data){
var response = data[0];
console.log(response)
this.setState({
question: response.question,
answer: response.answer
})
}.bind(this));
},
componentDidMount: function() {
this.serverRequest = this.getData()
},
checkAnswer: function(event) {
if(event.target.value.toLowerCase() === this.state.answer.toLowerCase()) {
this.setState({
score: this.state.score + 1,
value: ''
})
this.getData();
}
},
skipQuestion: function() {
this.getData();
},
render: function() {
var value = this.state.value
return (
<div>
<p>{this.state.question}</p>
<input type='text' value={value} onChange={this.checkAnswer}/>
<p onClick={this.skipQuestion}>New question</p>
<p>{this.state.score}</p>
</div>
)
}
});
答案 0 :(得分:1)
我将此代码移动到jsbin,您的输入清除逻辑正常运行。但是,正如@finalfreq在您的实现中提到的那样,无法在输入框中输入完整的答案,每个输入都会被识别但永远不会显示。对此的修复如下所示。唯一的变化是在else
中添加checkAnswer
案例:
var Quiz = React.createClass({
getInitialState: function() {
return {
question: '',
answer: '',
value: '',
score: 0
}
},
getData: function() {
$.get('http://jservice.io/api/random', function(data){
var response = data[0];
console.log(response)
this.setState({
question: response.question,
answer: response.answer
})
}.bind(this));
},
componentDidMount: function() {
this.serverRequest = this.getData()
},
checkAnswer: function(event) {
if(event.target.value.toLowerCase() === this.state.answer.toLowerCase()) {
this.setState({
score: this.state.score + 1,
value: ''
})
this.getData();
} else {
this.setState({
value: event.target.value.toLowerCase()
})
}
},
skipQuestion: function() {
this.getData();
},
render: function() {
var value = this.state.value
return (
<div>
<p>{this.state.question}</p>
<input type='text' value={value} onChange={this.checkAnswer}/>
<p onClick={this.skipQuestion}>New question</p>
<p>{this.state.score}</p>
</div>
)
}
});
