我被卡住了......我需要从列表公式中获取sorting table ...我从JSON文件中获取了3个参数并创建公式，现在我需要对此公式列表进行排序。
Json文件：https://api.coinmarketcap.com/v1/ticker/
<body>
<script>
$(document).ready(function() {
$("#getMessage").on("click", function() {
$.getJSON("https://api.coinmarketcap.com/v1/ticker/?limit=0", function(json) {

json.forEach(function(val) {

我试图使用不同的插件，如jQuery排序列表，我试图使用Sort()，但它不起作用！也许我需要重写代码到JavaScript，而不是使用jQuery。现在对我来说非常痛苦！
let myHtmlString = json.map(dataItem => ({...dataItem, formulaValue: formulaFunction(someValuesHere)}))
.sort((a, b) => a.formulaValue - b.formulaValue)
.map(dataItem => getMyHtml(dataItem))
.join('') ;
这就是你需要从json生成html字符串以使其工作的方式
ES5替代方案：
var myHtmlString = json.map(function(dataItem){
return Object.assign(dataItem, {formulaValue: getFormulaValue(dataItem.value1, dataItem.value2)})
})
.sort(function(a,b) {
return a.formulaValue - b.formulaValue;
})
.join('')
生成完整细节的html：
