UPD:如何在我的组件中显示数组的元素(WeatherCityName - h2)?可以看出数组已加载,但是当我指出属性时 - 发生错误,它可能是语法中的问题?
var WeatherBox = React.createClass({
handleWeatherSubmit: function(text) {
$.ajax({
url: this.props.url,
dataType: 'json',
type: 'POST',
data: 'cityName=' + text,
success: function(data) {
this.setState({data: data});
}.bind(this),
error: function(xhr, status, err) {
console.error(this.props.url, status, err.toString());
}.bind(this)
});
},
getInitialState: function() {
return {data: []};
},
render: function() {
return (
<div className="wetherBox">
<h1> Weather</h1>
<WeatherForm onWeatherSubmit={this.handleWeatherSubmit} />
<WeatherCityName data={this.state.data[0]} />
<WeatherList data={this.state.data} />
</div>
);
}
});
var WeatherCityName = React.createClass({
render: function(){
return(
<h2>{this.state.data[0].cityName}</h2>
);
}
});
答案 0 :(得分:0)
当然,只需将<h2>{weatherItem.cityName}</h2>
直接放在<div>
。
var WeatherList = React.createClass({
render: function() {
var weatherNodes = this.props.data.map(function(weatherItem) {
return (
<div className="city-item-with-title">
<h2>{weatherItem.cityName}</h2>
<WeatherItem
cityid={weatherItem.cityid}
type={weatherItem.type}
src={weatherItem.src}
temp={weatherItem.temp}
tempFrom={weatherItem.tempFrom}
tempTo={weatherItem.tempTo}
key={weatherItem.id}
/>
</div>
);
});
return (
<div className="weatherList">
{weatherNodes}
</div>
);
}
});
this.props.data[0]
?
