如何全面解决ECSHOP的jquery冲突

主要就是Ecshop的AJAX传输类，transport.js中重写了object的对象原型，从而导致了与jq框架的冲突。

解决：

1. 删除transport.js中587行 - 636行中关于object.prototype.toJSONString的定义

2. 自定义一个方法用于object对象的json序列化

如下

function obj2str(o)

{

//开始

var r = [];

if(typeof o =="string") return "\""+o.replace(/([\'\")/g,]\\])/g,"\\$1").replace(/(\n)/g,"\\n").replace(/(\r)/g,"\\r").replace(/(\t)/g,"\\t")+"\"";

if(typeof o =="undefined") return "undefined";

if(typeof o == "object"){

if(o===null) return "null";

else if(!o.sort){

for(var i in o)

{

if(i!="toJSONString") //增加判断，清除对object原型的定义加入到json中

r.push("\""+i+"\""+":"+obj2str(o));

}

r="{"+r.join()+"}";

}else{

for(var i =0;i<o.length;i++)

r.push(obj2str(o))

r="["+r.join()+"]"

}

return r;

}

return o.toString();

//结束

}

3. 在模板页和js脚本中所有对于obj.toJSONString()的地方，一概替换为obj2str(obj)

4. 重写好后发现compare.js, 主要重写其中的定时器功能。 将以下代码替换到compare.js中

var Compare = new Object();

Compare = {

add : function(goodsId, goodsName, type)

{

var count = 0;

for (var k in this.data)

{

if (typeof(this.data[k]) == "function")

continue;

if (this.data[k].t != type) {

alert(goods_type_different.replace("%s", goodsName));

return;

}

count++;

}

if (this.data[goodsId])

{

alert(exist.replace("%s",goodsName));

return;

}

else

{

this.data[goodsId] = {n:goodsName,t:type};

}

this.save();

this.init();

},

init : function(){

this.data = new Object();

var cookieValue = document.getCookie("compareItems");

if (cookieValue != null) {

this.data = cookieValue.parseJSON();

}

if (!this.compareBox)

{

this.compareBox = document.createElement_x("DIV");

var submitBtn = document.createElement_x("INPUT");

this.compareList = document.createElement_x("UL");

this.compareBox.id = "compareBox";

this.compareBox.style.display = "none";

this.compareBox.style.top = "200px";

this.compareBox.align = "center";

this.compareList.id = "compareList";

submitBtn.type = "button";

submitBtn.value = button_compare;

this.compareBox.appendChild(this.compareList);

this.compareBox.appendChild(submitBtn);

submitBtn.onclick = function() {

var cookieValue = document.getCookie("compareItems");

var obj = cookieValue.parseJSON();

var url = document.location.href;

url = url.substring(0,url.lastIndexOf('/')+1) + "compare.php";

var i = 0;

for(var k in obj)

{

if(typeof(obj[k])=="function")

continue;

if(i==0)

url += "?goods[]=" + k;

else

url += "&goods[]=" + k;

i++;

}

if(i<2)

{

alert(compare_no_goods);

return ;

}

document.location.href = url;

}

document.body.appendChild(this.compareBox);

}

this.compareList.innerHTML = "";

var self = this;

for (var key in this.data)

{

if(typeof(this.data[key]) == "function")

continue;

var li = document.createElement_x("LI");

var span = document.createElement_x("SPAN");

span.style.overflow = "hidden";

span.style.width = "100px";

span.style.height = "20px";

span.style.display = "block";

span.innerHTML = this.data[key].n;

li.appendChild(span);

li.style.listStyle = "none";

var delBtn = document.createElement_x("IMG");

delBtn.src = "themes/default/images/drop.gif";

delBtn.className = key;

delBtn.onclick = function(){

document.getElementByIdx_x("compareList").removeChild(this.parentNode);

delete self.data[this.className];

self.save();

self.init();

}

li.insertBefore(delBtn,li.childNodes[0]);

this.compareList.appendChild(li);

}

if (this.compareList.childNodes.length > 0)

{

this.compareBox.style.display = "";

this.timer = window.setInterval("flowdiv('compareBox')", 50);

}

else

{

this.compareBox.style.display = "none";

window.clearInterval(this.timer);

this.timer = 0;

}

},

save : function()

{

var date = new Date();

date.setTime(date.getTime() + 99999999);

document.setCookie("compareItems", obj2str(this.data));

},

lastScrollY : 0

}

//用于定时器的自动滚动的层

lastScrollY=0;

function flowdiv(domid){

　　　var diffY;

　　　　if (document.documentElement && document.documentElement.scrollTop)

　　　　　　diffY = document.documentElement.scrollTop;

　　　　else if (document.body)

　　　　　　diffY = document.body.scrollTop

　　　　else

　　　　　　{}

　　　　//alert(diffY);

　　　　percent=.1*(diffY-lastScrollY);

　　　　if(percent>0) percent=Math.ceil(percent);

　　　　else percent=Math.floor(percent);

　　　　document.getElementByIdx_x(domid).style.top=parseInt(document.getElementByIdx_x(domid).style.top)+percent+"px";

　　　　lastScrollY=lastScrollY+percent;

　　　　//alert(lastScrollY);

}
