如何通过Ajax调用外部javascript

Question

我对Ajax完全陌生。在我们的网站上，我们有一个购物车页面，用户可以使用ajax添加，删除和更改物品数量，而无需为购物车整页加载。我的问题是，当用户更新他的购物车项目时，我需要启动一些第三方外部呼叫。

我有这个ajax调用哪个调用评估脚本参数的jsp。现在这个jsp包含第三方外部脚本，我明白需要单独解雇。下面我列举加入我的代码，并会很感激，如果有人能帮助

var callExternalUpdate = function(secure) { 
    var ajaxParams = "secure=" + secure; 
    ajax('POST', 
     '/abc/my-ajax.jsp', 
     ajaxParams, 
     function(r) { 
      eval(r.responseText); 
     }, 
     function(r) { 
      //alert(r.responseText); 
     } 
    ); 
} 

下面

是我-ajax.jsp

<script type="text/javascript" src="http://www.mywebsite.com/js/criteo_ld_0.5.4.js" async="true"></script> 
<script type="text/javascript">var CRITEO_CONF = [[{ 
    pageType: 'basket', 
    'Product IDs': [123], 
    'Prices': [10], 
    'Quantities': [1] 
    }], [6507,'ppr','us.','110',[[7721658, 7721659]],{'Product IDs':['i',1], 'Prices':['p',1], 'Quantities':['q',1]}]]; 
    if (typeof (CRITEO) != "undefined") { CRITEO.Load(false); } 
</script> 

我知道我会为我使用被忽略的标签代码eval在我的javascript.But如何调用外部JavaScript？

请帮忙。

TIA
