javascript - How to redefine js parameters externally

Question

How to redefine the data parameter in the js file externally?

digg: function(obj, projId, subjId, optId) {
    data = {
        'answer': JSON.stringify(answer),
        'login': 1,
        'source': 1,
        'g_tk': generateToken(getKey()),
        'format': 'script',
        'callback': 'parent.AppPlatform.Survey.Digg.ReceiveDiggResult'
    }
}

Answer 1

data = {
        'answer': 'answer',
        'login': 1,
        'source': 1,
        'g_tk': 'g_tk',
        'format': 'script',
        'callback': function(){}
}

就可以了，data没有写var。会绑在外面的

Answer 2

digg: function(obj, projId, subjId, optId) {
    data = {
        'answer': JSON.stringify(answer),
        'login': 1,
        'source': 1,
        'g_tk': generateToken(getKey()),
        'format': 'script',
        'callback': 'parent.AppPlatform.Survey.Digg.ReceiveDiggResult'
    };
}

data = {};

That’s it. The scope of data within the function is only valid inside the function, so redefining data outside the function does not affect the operation of data inside the function at all.
