使用来自loopj.com的jQuery tokeninput
我可以选择从 .jsp 文件以 JSON 格式发送的多个选项。但是，当我想提交/访问文本输入元素“tokenize”中的值时，我得到未定义的输出。我是java脚本的新手，所以什么该碰，什么不该碰。
问：有人可以向我提供/指出如何尽早实现这一目标的一些细节吗？ 下面是不是少了点什么？
提前致谢， Aditya
注意： body 标签被分割成一个单独的代码块。请不要混淆。

$("#tokenize2").tokenInput("getData.jsp", {

});
});

I am able to select multiple options that I send from my .jsp file in JSON format. However, when I want to SUBMIT/access the values from the text input element "tokenize", I get a undefined output. I am a novice to java script and so what to touch and what not to touch.
Q: Could someone provide/point me to some detail on how to achieve this at the earliest??
Is there something missing below?
Thnx in Advance,
Aditya
Note: The body tag got split into a separate code block. Pls donot get confused.
