如何在Javascript中侦听Tapped事件

Question

I have the following sample function code to be called when the user Tap on a word and then tapped event should occur to Unhighlight that selected text.But in Javascript there is no such event.

 deleteHighlight:function(){
    var element = contentDoc.getElementsByClassName('highlighted');
    element.style.backgroundColor = "white";  
}

How to listen for that event and handle the same when the user tap on that word.?

any help is highly appreciated.

Note :No jquery please.I want this to be done only in javascript

您可以使用touchstart当字被窃听和touchend以恢复至原始状态
