js委托事件 转

document.getElementById("spec_area").addEventListener("click",function(e) {   // 检查事件源e.targe是否为Li   //console.log(e.target);  // console.log(e.target.nodeName);    if(e.target && e.target.nodeName == "INPUT") {     // // 真正的处理过程在这里     // console.log("List item ",e.target.id.replace("post-")," was clicked!");     console.log("111");     console.log(e.target);     var target=e.target;     target.onkeyup=function(){         console.log("111");         document.getElementById("new_library").innerHTML='';     }    } });

网上的example

document.getElementById("parent-list").addEventListener("click",function(e) {
  // 检查事件源e.targe是否为Li
  if(e.target && e.target.nodeName.toUpperCase == "LI") {
    // 真正的处理过程在这里
    console.log("List item ",e.target.id.replace("post-")," was clicked!");
  }
});
