如何通过Ajax调用加载外部javascript

我对阿贾克斯完全陌生。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、删除和更改商品数量，而不必为购物车加载整个页面。我的问题是，每当用户更新购物车项目时，我需要触发一些第三方外部呼叫

我有一个ajax调用，它调用jsp来计算脚本的参数。现在，这个jsp包含第三方外部脚本，我理解它需要单独启动。我正在下面添加我的代码，如果有人能帮助我，我将不胜感激

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my-ajax.jsp中的代码

<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>

变量CRITEO_CONF=[{
页面类型：'basket'，
“产品ID”：[123]，
“价格”：[10]，
“数量”：[1]
}]，[6507，'ppr'，'us'，'110'，[[7721658，7721659]]，{'Product ID'：[i'，1]，'Prices'：[p'，1]，'Quantity'：[q'，1]}]；
if（typeof（CRITEO）！=“undefined”）{CRITEO.Load（false）；}

我知道当我在javascript中使用eval时，我将省略标记。但是我如何调用外部javascript呢

请帮忙

TIA

让criteo\u ldu\u 0.5.4.js加载页面，让JSP页面只返回java脚本表达式的值，而不返回任何脚本标记

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); }

就这些。。。

谢谢。除了使用jquery还有其他方法吗？您可以向dom添加标记。请参阅：在eval响应之后，我需要在ajax调用中调用这个外部脚本。我该怎么做？在eval之后添加此行。document.write（unescape（“%3Cscript src='mywebsite.com/js/criteo\u ld_0.5.4.js'async='true'type='text/javascript'%3E%3C/script%3E”）；
