Chrome AppWindow捕获鼠标事件

Question

Chrome应用窗口最初没有针对性。当您单击窗口区域时，它将获得焦点。但是，此时不会捕获鼠标单击事件。我想知道如何在窗口获得焦点时捕获鼠标事件。我的意思是只是鼠标点击事件，它将窗口从背景带到前台。

将window.onfocus事件与click事件结合使用。

这里你去：jsfiddle.net/MarcGuiselin/7vyey4Ld/1

var justfocused=false;//true for 500ms after the page was focused
document.body.onclick=function(e){//onclick event always occurs after onfocus event
  if(justfocused){//if our window was just focused
    justfocusedevent(e);
    justfocused=false;//user has to refocus this tab for this function to run again
  }else{
    console.log("just a regular click");
  }
}

window.onfocus=function(){
  justfocused=true;
  setTimeout(function(){justfocused=false;},500);//reset just in case
  console.log("window focused");
}

function justfocusedevent(e){
    console.log("we just focused on this window at: ("+e.clientX+","+e.clientY+")");
}

尝试多次单击红色结果页面，然后单击其他位置以取消聚焦结果窗口并再次单击它。
