我有一个包含 React 组件字符串名称的数组(“SampleWidget1”);它由外部机制填充。在我的 DashboardInterface 组件中,我想使用该数组,呈现其中包含的组件,并在 DashboardInterface.render 函数中的其他静态定义的 HTML 中显示它。我怎样才能在 React 中做到这一点?
以下是我的尝试;没有错误,但是渲染的组件实际上从未成功插入到 DOM 中。如果我手动将 SampleWidget1 添加到 DashboardInterface.render 函数 () 中,它会按预期显示。如果我对动态渲染的组件做同样的事情,它就不会出现。
有什么建议?
var widgetsToRender = ["SampleWidget1"];
/**
* Dashboard that uses Gridster.js to display widget components
*/
var DashboardInterface = React.createClass({
/**
* Loads components within array by their name
*/
renderArticles: function(widgets) {
if (widgets.length > 0) {
var compiledWidgets = [];
// Iterate the array of widgets, render them, and return compiled array
for(var i=0; i<widgets.length; i++){
compiledWidgets.push(React.createElement(widgets[i] , {key: i}));
}
return compiledWidgets;
}
else return [];
},
/**
* Load the jQuery Gridster library
*/
componentDidMount: function(){
// Initialize jQuery Gridster library
$(".gridsterDashboard ul").gridster({
widget_margins: [10, 10],
widget_base_dimensions: [140, 140],
//shift_larger_widgets_down: false
});
},
render: function() {
// Get the widgets to be loaded into the dashboard
var widgets = this.renderArticles(widgetsToRender);
return (
<div className="gridsterDashboard">
<ul >
{this.widgets}
<SampleWidget1 />
</ul>
</div>
);
}
});
这是我尝试渲染的示例组件:
/**
* Sample component that return list item that is to be insert into Gridster.js
*/
var SampleWidget1 = React.createClass({
render: function() {
// Data will be pulled here and added inside the list item...
return (
<li data-row="1" data-col="1" data-sizex="2" data-sizey="1">testing fake component</li>
)
}
});
ReactDOM.render(
<DashboardInterface />,
document.getElementById('dashboard')
);
