如何在AJAX成功函数中传递额外的数据？

Question

I have a function:

function Activity() {
    this.LoadFile = function (path, onSuccess) {
        $.ajax({
            url: path,
            dataType: 'html',
            success: onSuccess
        });
    };
}

At the moment I call it like this:

var activity = new Activity();

activity.LoadFile('../file.htm', function (data) {
    console.log(data);
});

What I would like to do, is to add some default values in the AJAX success callback. Lets say that for example, I always want to log the data by default, without writing it every time I do a LoadFile . Hope you get the point, thanks in advance.

Answer 1

You could make a wrapper function that logs/etc then calls the onSuccess function:

this.LoadFile = function (path, onSuccess) {
    var onSuccessWrapper = function(data) {
      console.log(data)
      onSuccess(data)
    }
    $.ajax({
        url: path,
        dataType: 'html',
        success: onSuccessWrapper
    })
}

Answer 2

you could do the folowing

$.ajax({
    url: path,
    dataType: 'html',
    success: function(data, textStatus, jqXHR) {
        console.log(data);
        onSuccess(data, textStatus, jqXHR);
    }
});

Hi have you tried this?

 $.ajax({
        url: path,
        dataType: 'html',
        success: function(data){
            onSuccess(data);
            alert(data);//default here
        }
    });
