今天弄好久。直接拿例子吧。

function addWatchItem(param1,param2){
$.ajax({
url : ‘addWatchItem.html‘,
data : {auctionItemId: param1, flag:param2},
success : function(data){
if(data=="error"){
alert("内部错误！");
return false;
}

}
});
}

按照我们的写法习惯。我写成了$.ajax  但是一直报错。。包的错误为has no method ‘ajax‘    

Uncaught
TypeError: Object # has no method ‘ajax‘

后来在google上查找

Looking at the definition of $ in
your code, it seems like you‘re using the Prototype framework as well. A problem when using multiple libraries is that they are overwriting variables, mainly the $.

In your case, use jQuery instead
of $ (so jQuery.ajax(...)),
or use jQuery.noConflict to restore the $ back
to the jQuery one.

将如上代码 中的$改为 jquery

即:

function addWatchItem(param1,param2){
jquery.ajax({
url : ‘addWatchItem.html‘,
data : {auctionItemId: param1, flag:param2},
success : function(data){
if(data=="error"){
alert("内部错误！");
return false;
}

}
});
}

神奇的好了。
