XHR响应中不必要的逗号最终出现在表格的单元格中 [英] Unwanted comma in XHR response ending up in table's cells

问题描述

我有一个XHR响应，看起来像这样:

I have an XHR response that looks something like this:

[
    [
        "e33222",
        "1730-06-27",
        "Lewis Morris",
        [
            "Edward Wynne; ",
            "William Bulkeley"
        ]
    ], [...]
]

它用于填充表

var table = $('#mainTable').DataTable()
table.rows.add(result)
table.draw();

除了在每个后续子项的开头添加一个令人讨厌的逗号(或者更好的是，在每个具有子项的第一个子项的末尾添加逗号，请参见"Edward Wynne;"， 威廉·伯克利").

It all works great, except for an annoying comma added at the beginning of every subsequent sub-item (or, better, at the end of every first sub-item which has a following one, see "Edward Wynne; ", "William Bulkeley").

最终结果是，在与我得到的数据相对应的单元格中:

The end result is that in the cell corresponding to that data I get:

William Morris; ,Richard Morris

有什么办法获取:

William Morris; Richard Morris

?

推荐答案

因此，请先遍历数据，然后再将其设置在数据表中并格式化数据，使其不是数组.

So loop over the data before you set it in the datatable and format the data so it is not an array.

var results = [
    [
        "e33222",
        "1730-06-27",
        "Lewis Morris",
        [
            "Edward Wynne; ",
            "William Bulkeley"
        ]
    ],
    [
        "22222",
        "2222-06-27",
        "foooo Mooooo",
        [
            "foo bar; ",
            "foo baz"
        ]
    ],    
]

results.forEach(function (record) {
  record[3] = record[3].join('')
})
console.log(results);
