Js生成json数据并导出json文件
目录
前言
在实际开发中或者自己学习中经常需要使用到json数据，这时候这个就可以自己
搞定。
一、生成数据
InitDataFun() {
let ListData = [];
let FirstContentData = [];
let SecondContentData = [];
let ThirdContentData = [];
let FourContentData = [];
for (var i = 0; i < 16; i++) {
if (i < 6) {
FirstContentData.push({
Name: "一级水厂" + (i + 1),
Label: "一级水厂" + (i + 1),
Status: 0,
Msg: [],
IsFather: true,
Depth: 1,
Time: "13:0" + i,
Id: "Firstid" + (i + 1),
LID: "Firstlid" + (i + 1),
List: [
{
Title: "浊度",
Data: 0.23,
},
{
Title: "PH",
Data: 3,
},
{
Title: "湿度",
Data: 0.63,
},
{
Title: "COD",
Data: 0.23,
},
],
});
let ListDataSec = [];
for (var Seci = 0; Seci < 16; Seci++) {
let ListDatarsd = [];
for (var Rsdi = 0; Rsdi < 16; Rsdi++) {
let ListDataFour = [];
for (var Fouri = 0; Fouri < 16; Fouri++) {
ListDataFour.push({

IsFather: false,

},
],
});
}
ListData.push({

Label: "一级水厂" + (i + 1),
Status: 0,
Msg: [],
IsFather: true,
Depth: 1,
Time: "13:0" + i,
Id: "Firstid" + (i + 1),
LID: "Firstlid" + (i + 1),
ShowCode: "一级---" + (i + 1),
List: [

});
}
SecondContentData.push({

List: [

],
});
ThirdContentData.push({

}
this.FirstContentData = FirstContentData;

this.ListData = SecondContentData;
this.ShowListData = JSON.stringify(SecondContentData);
// console.log("ListData",ListData)
//console.log("JSON.stringify(ListData)", JSON.stringify(ListData));
},二、导出json文件
saveJSON(data, filename) {
if (!data) {
alert("保存的数据为空");
return;
}
if (!filename) filename = "json.json";
if (typeof data === "object") {
data = JSON.stringify(data, undefined, 4);
}
var blob = new Blob([data], { type: "text/json" }),
e = document.createEvent("MouseEvents"),
a = document.createElement("a");
a.download = filename;
a.href = window.URL.createObjectURL(blob);
a.dataset.downloadurl = ["text/json", a.download, a.href].join(":");
e.initMouseEvent(
"click",
true,
false,
window,
0,
0,
0,
0,
0,
false,
false,
false,
false,
0,
null
);
a.dispatchEvent(e);
},三、完整代码
<template>
