我非常需要jQuery Api,但事情是我使用了React js的api。我只是混淆了我的React js生命週期。 附加信息我正在爲不同div創建視圖計數器。在我看來點我很喜歡jQuery的API來照顧高度,scrollTop的.. 下面的代碼將輸出未定義如何整合jQuery與React js?
var React = require('react');
var ReactDOM = require('react-dom');
var NewsDetail = require('./news-details');
var $ = require('jquery');
module.exports = React.createClass({
getInitialState:function() {
return{
news:[
{
{
id:"5",
data:"I probably am using the wrong I probably am using the wrong terminology here but this is what I'm trying to do. I want to create a map with a value terminology here but this is what I'm trying to do. I want to create a map with a value for each key and a value for each key's object. S"
},
{
id:"6",
data:"I probably am using the wrong I probably am using the wrong terminology here but this is what I'm trying to do. I want to create a map with a value I probably am using the wrong terminology here but this is what I'm trying to do.

},
componentWillMount:function() {
},
componentDidUpdate:function() {
var height = $('#newscontainer').height();
alert(height)//udefined
},
render:function() {
var newsdata = this.state.news.map(function (newss) {
return(<NewsDetail key={newss.id} {...newss}/>)

return(
<div className="newscontanier" id="newscontanier">{newsdata}</div>
)
}
})
?如果你只是獲得元素的高度,你可以做到沒有jQuery。 –
var height = $('#newscontainer')。height();根據您的DOM選擇錯誤的ID。 ... id =「newscontanier」 –
您的ID在您的渲染功能中拼寫錯誤。 – ray
