javascript - 如何在 JavaScript 中将 .txt 文件中的数据保存到数组中？

Question

我有这个文件“File.txt”，格式为大array[ ] ，在 .txt 文件中放置的该数组的每个索引中，都有一个我稍后要使用的 json 。我需要读取文件，保存每个 json 并使用 javascript 将其推送到 数组 中。每{ content } , { content 2}代表一个 json 。

文件.txt

[
 {
  "nodes": [
    {"id": "Source","label":"name","group": 0},
    {"id": "Parent_1","label":"name","group": 1},
    {"id": "Parent_2","label":"name","group": 1},
    {"id": "Parent_3","label":"name","group": 1},
    {"id": "Child_1","label":"name","group": 2},
    {"id": "Child_2","label":"name","group": 2},
    {"id": "Child_3","label":"name","group": 2},
    {"id": "Child_4","label":"name", "group": 3}
  ],
  "links": [
    { "source": "Source","target": "Parent_1"},
    { "source": "Source","target": "Parent_2"},
    { "source": "Source","target": "Parent_3"},
    { "source": "Source","target": "Child_1"},
    { "source": "Source","target": "Child_2"},
    { "source": "Source","target": "Child_3"},
    { "source": "Child_2","target": "Child_4"}
  ]
} ,
{
  "nodes": [
    {"id": "Source","label":"name","group": 0},
    {"id": "Parent_1","label":"name","group": 1},
    {"id": "Parent_2","label":"name","group": 1},
    {"id": "Parent_3","label":"name","group": 1},
    {"id": "Child_1","label":"name","group": 2},
    {"id": "Child_2","label":"name","group": 2},
    {"id": "Child_3","label":"name","group": 2},
    {"id": "Child_4","label":"name", "group": 3}
  ],
  "links": [
    { "source": "Source","target": "Parent_1"},
    { "source": "Source","target": "Parent_2"},
    { "source": "Source","target": "Parent_3"},
    { "source": "Source","target": "Child_1"},
    { "source": "Source","target": "Child_2"},
    { "source": "Source","target": "Child_3"},
    { "source": "Child_2","target": "Child_4"}
  ]
} 
]

我想到的是这样的:

//The array i want to save all the data in
NewArray=[];

//Get the file name
 var File = document.getElementById('File.txt');

//Make a loop so i can read each index of the file and save the content in the new array
for (i = 0; i < array.length; i++) { 
    NewArray[i] = "File.[i] ;
}

这样做

$(document).ready(function() {
    $("#lesen").click(function() {
        $.ajax({
            url : "helloworld.txt", //get the file from local/server 
            dataType: "text",
            success : function (data) {
                var arrData = data; //data are in the form of array with json data
            }
        });
    });
});
