get a value from a serialized string
提问by pnm123
There is a form, and on submit, I convert it to a serialized string to in order to submit the form via ajax.
有一个表单，在提交时，我将其转换为序列化的字符串，以便通过 ajax 提交表单。
var data = $$.serialize();
Now there is an input field named 'title' and I want to get its value to show a message. So I am looking for a method to do just that. I've tried;
现在有一个名为“title”的输入字段，我想获取其值以显示消息。所以我正在寻找一种方法来做到这一点。我试过了;
alert(data.name);
But found out it's not the method.
但发现这不是方法。

You don't need jQuery at all. Just do this:
你根本不需要 jQuery。只需这样做：
$('#frmEditTab').submit(function(e){
e.preventDefault();
var title = this.title; //get the input named "title" of the form
alert(title.value); //alerts the value of that input
});
