如何使json更清晰

标签: javascript json

我看过一些问题,比如: How can I pretty-print JSON using JavaScript?Javascript: How to generate formatted easy-to-read JSON straight from an object?http://jsfiddle.net/AndyE/HZPVL/

但我无法让它为我工作。我一定做错了什么?有人可以建议吗?

我尝试将'\ t'添加到stringify部分,但它对我不起作用

$(document).on("click", "#doBackupBtn", function(e) {
    e.preventDefault();
    console.log("Begin backup process");

    $.when(
        backup("allergies")

    ).then(function(allergies, log) {
        console.log("All done");
        //Convert to JSON
        var data = {allergies:allergies}
        var serializedData = JSON.stringify(data, '\t');
        console.log(serializedData);
        (function(console){

console.save = function(data, filename){

    if(!data) {
        console.error('Console.save: No data')
        return;
    }

    if(!filename) filename = 'console.json'

    if(typeof data === "object"){
        data = JSON.stringify(data)
    }

    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)
 }
})(console)

\t是第三个参数。在浏览器控制台上尝试此操作(FF Ctrl + Shift + K):

console.log(JSON.stringify({"a": {"b": "c"}}, null, 4));

结果:

"{ "a": { "b": "c" } }"

您缺少JSON.stringify(obj, undefined,2)
