我正在开发一款基于地图的应用,该应用使用Google Map API在React.js中创建标记及其信息窗口。 infowindow.setContent()
只接受String
或HTML
。我传递String
是不可能的,因为我有button
链接到另一个反应组件中的特定方法(类似于:_this.props.addList(place)
)。因此,我必须将参数填充为HTML DOM,如以下代码行所示:
var div = document.createElement('div');
var title = document.createElement('h4');
title.innerHTML = place.name;
var btn = document.createElement('button');
btn.className = 'btn btn-danger btn-block';
btn.appendChild(document.createTextNode('I want to go here !!'));
div.appendChild(title).appendChild(btn);
google.maps.event.addListener(marker, 'click', function() {
infowindow.setContent( div );
infowindow.open(map, this);
});
btn.addEventListener('click', function() {
_this.props.addList(place);
});
这些代码对我有用,但我不想逐一创建元素。我也尝试用React组件传递参数,但它似乎不起作用:
createMarker: function() {
/** Some other lines of code */
var _this = this;
google.maps.event.addListener(marker, 'click', function() {
infowindow.setContent( _this._renderInfoWindow(place) );
infowindow.open(map, _this);
});
},
// my infowindow rendering method
_renderInfoWindow: function(place) {
return(
<div>
<h4>{place.name}</h4>
<p>{place.cost}</p>
<button className="btn btn-danger btn-block" onClick={this.props.addList.bind(this, place)}>I want to go here !! </button>
</div>
)
},
那么还有另一种方法可以至少将react组件转换为HTML,这样我就不必一个一个地编写document.createElement()
吗?

您可以通过React.render
在分离的DOM节点中呈现ReactElement。因此,以下代码应该适合您。
createMarker: function() {
/** Some other lines of code */
_this = this;
google.maps.event.addListener(marker, 'click', function() {
var div = document.createElement('div');
ReactDOM.render( _this._renderInfoWindow(place), div );
infowindow.setContent( div );
infowindow.open(map, this);
});
},

您也可以使用React的renderToString()方法
_renderInfoWindow: function(place) {
return React.renderToString(
<div>
<h4>{place.name}</h4>
<p>{place.cost}</p>
<button className="btn btn-danger btn-block" onClick={this.props.addList.bind(this, place)}>I want to go here !! </button>
</div>
);
}
这应该适用于一个简单的组件,如图所示。 React.renderToString()将仅返回组件的html。

对于较新版本的React
import ReactDOMServer from "react-dom/server";
let html = ReactDOMServer.renderToString(<div>...</div>)
答案 3 :(得分:1)
这应该呈现HTML。
import ReactDOMServer from "react-dom/server";
const html = ReactDOMServer.renderToString(<div>...</div>)

// Create a DOM element to hold the react component.
var span = document.createElement('span');
// Render the React component.
React.render(h.button(null, 'Buttonz!'), span);
// This will give the result as a string, which is useful if you've escaped
// React's context (e.g. inside DataTables).
// Obviously, the component will no longer be reactive but this is a
// good way to leverage simple stuff you've already written in React.
// In my case, I'm primarily leveraging React wrappers around Bootstrap components.
// The important thing is that componentDidMount gets called.
return span.outerHTML;
