这是我的代码

JScript code

function setu(s) {    // var thisObject = evt.srcElement || evt.target;    var thisObjectParent = s.parentNode;    var childArray = thisObjectParent.childNodes;    var text = s.innerHTML;    var newchild = document.createElement("strong");    thisObjectParent.replaceChild(newchild, s);    newchild.innerHTML = text;    return false;      }function changenav(s) {    var thisObjectParent = s.parentNode;    var childArray = thisObjectParent.childNodes;    //alert(childArray[0].tagName + "," + childArray[1].tagName + "," + childArray[2] + "," + childArray[3] + "," + childArray[4]);    // alert(s.innerHTML);    var anewchild = document.createElement("A");    for (var i = 0; i < childArray.length; i++) {        if (childArray[i] != s && childArray[i].tagName == "A") {            // return !setu(s);            childArray[i].onclick = "";           // childArray[i].innerHTML = "haha";        }        if (childArray[i] == s) {            setu(s);            //alert(s.tagName)        }       // alert(childArray[i] != s);  } return false;}

JScript code

        if (childArray[i] != s && childArray[i].tagName == "A") {            // return !setu(s);            childArray[i].onclick = ""; //问题可能出在这一行，执行后解除了原先绑定到所有没有被点击的链接的onclick事件处理函数           // childArray[i].innerHTML = "haha";        }
