DOMInspector.js
轻松使DOM检查器能够将鼠标悬停在页面上的项目上，然后单击即可检索元素。
如何使用DOMInspector：
//Start the mouseover / click capture, and add a callback function to be called when click occurs
DOMInspector.startCapture( myCallbackFunction );
...
function myCallbackFunction() {
console.log( 'Selected Element: ', DOMInspector.getSelectedElement() );
}
