JSONP回调不起作用 - 甚至函数都是全局的

Question

我想调用跨域上的API。这是我做的：

$(document).ready(function() {
    var pm_url = 'http://localhost:8080/alfresco/service/api/login';
    pm_url += '?u=${args.user}&pw=${args.pass}&format=json';
    $.ajax({
        url: pm_url,
        dataType: 'jsonp',
        jsonp: 'callback',
        jsonpCallback: 'redirect'
    });
});

var redirect=function(data) {
        var token= JSON.parse(data);

        alert(token.data.ticket);
        var entity="";
        var id="";
        var rows="";
        var sortColumn="";
        var sortType="";
        var sAuthor="";
        var permission="";
        var branch="";
        var category="";
        var subCategory="";
        var jurisdiction="";
        var baseDocket="";

        <#if (args.entity) ??>
            entity= "${args.entity}";
        </#if>
        <#if (args.id) ??>
            id= "${args.id}";
        </#if>
        <#if (args.rows) ??>
            rows= "${args.rows}";
        </#if>
        <#if (args.sortColumn) ??>
            sortColumn= "${args.sortColumn}";
        </#if>
        <#if (args.sortType) ??>
            sortType= "${args.sortType}";
        </#if>
        <#if (args.sAuthor) ??>
            sAuthor= "${args.sAuthor}";
        </#if>
        <#if (args.permission) ??>
            permission= "${args.permission}";
        </#if>
        <#if (args.branch) ??>
            branch= "${args.branch}";
        </#if>
        <#if (args.category) ??>
            category= "${args.category}";
        </#if>
        <#if (args.subCategory) ??>
            subCategory= "${args.subCategory}";
        </#if>
        <#if (args.jurisdiction) ??>
            jurisdiction= "${args.jurisdiction}";
        </#if>
        <#if (args.baseDocket) ??>
            entity= "${args.baseDocket}";
        </#if>

        var url="http://localhost:8080/alfresco/s/documentManagement?entity="+entity+"&id="+id+"&rows="+rows+"&sortColumn="+sortColumn+"&sortType="+sortType+"&sAuthor="+sAuthor+"&permission="+permission+"&branch="+branch+"&category="+category+"&subCategory="+subCategory+"&jurisdiction="+jurisdiction+"&baseDocket="+baseDocket+"&alf_ticket="+token.data.ticket;

        window.location.replace(url);

};

但我得到了这个：  登录？u = admin＆amp; pw = admin＆amp; format = json＆amp; callback = redirect＆amp; _ = 1471932310898：2 Uncaught SyntaxError：意外的令牌：

我哪里出错了？请纠正我。
