phpfunction array_chunk(input, size, preserve_keys) {

  var x, p = '',
    i = 0,
    c = -1,
    l = input.length || 0,
    n = [];

  if (size < 1) {

Your keys are all the same and can be saved as an array. Get your original data every 11, then traverse the object by key and value respectively, and finally push it into the result array.

Use Underscore
The code is as follows

var label = ["学号","姓名","学期","课程","类别","学分","成绩","成绩类型","绩点","课程彪悍","课时"],
    arr = ***;
_.map([_.head(arr), _.tail(arr)], function(arr){
    return _.object(label, arr);
});

If the order remains unchanged, just use a for loop
