我应该在 onclick 上放置什么事件？

Question

<img src="image1.png" onclick="handler(this.src)" />

function handler(event, handler_src){
  if(onClickOn){
    companyJes(handler_src);
  }else{
    event.preventDefault(); // don't do anything
    event.stopPrpagation(); // really don't do anything

    return false; //make sure you don't do anything
  }
}

on the onclick handler(what should i put this ?, this.src); what should i put variable on onclick to replace the event ?

i tested handler(event, this.src); but it didt work.

You need to pass the event object in the handler. Eg:

handler(event)

Because "this" will the HTML element which called the handler function
