Question

我试图使用jquery发出GET请求来接收具有用户确定的命名空间的页面。我的索引页面（在jade中）有一个文本输入表单，该脚本使用：

org.skife.jdbi.v2.exceptions.UnableToExecuteStatementException: org.h2.jdbc.JdbcSQLException: Cannot parse "TIMESTAMP" constant "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"; SQL statement:

该应用程序使用路由器进行所有＆＃39; / chat＆＃39;请求，据我所知，请求url localhost：3000 / chat / namespace进入路由器，其中包含以下代码：

script(src="http://code.jquery.com/jquery-1.11.1.js")
script(type="text/javascript"). 
            $(document).ready(function(){
                $('form').submit(function(){
                    $.get('http://localhost:3000/chat/' + $('#n').val());
                });
            });

然后使用用户确定的命名空间呈现另一个jade文件。但是，在索引页面上提交表单只是刷新索引页面，地址栏显示router.use(function(req, res){ var namespace = req.originalUrl; res.render('../views/chat', {namespace: namespace, pageTitle: 'chatroom'}); });。我不确定我的语法是否错误，或者我尝试做的事情是否存在更深层次的问题。我尝试过$ .get（）其他字符串，例如＆＃39; / chat＆＃39;。

尝试

$(document).ready(function(){
    $('form').submit(function(event){
        $.get('http://localhost:3000/chat/' + $('#n').val());
        event.preventDefault();  //<--- prevent form from submitting, which will refresh the page before the AJAX call completes
    });
});

localhost中的jquery $ .get没有收到响应
