这是我的组件的结构:如何在数据更新后重新呈现Reactjs组件?
module.exports = React.createClass({
getInitialState(){
data = .... //by connecting to a db server
var properties = fun(...) //other functions manipulating the data
return {
data:data,
.... //other UI functions
}
onSearch(e){
e.preventDefault();
var startdate = React.findDOMNode(this.ref.start).value;
//******** here I want to update the data in the view using this new startdate
//so essentially I just want to replace "data = " in the getInitialState() bcoz I
//want other data manipulation functions from getInitialState to run as well.
}
render(){
return(
<form className = "dateform" onSubmit = {this.onSearch}>
<input type = "text" ref = "start" />
</form>
...
//other UI return stuff
)
}
)}
我应该如何去这样做// *******?
我想只更新getInitialState()中的数据变量,这取决于我在表单域中获得的日期。随后使用新数据刷新视图。我应该在onSearch函数中做什么改变?
这是一个正确的方法吗?
onSearch()
{
data = //make $.ajax call to get new data
this.setState({
data: data
});
}
