無法在highcharts上顯示json數據
[英]unable to display json data on highcharts
問題描述
我正在嘗試在頁面上建立一個圖表。 我確實獲得了圖表框架和標題，但現在有了線條或圖例。 當我做：
document.write(output)

我確實得到了格式正確的json輸出。 這個腳本可能遺漏的任何想法：

//init this script when the page has loaded
$(document).ready(function(){
$("#submitbutton").on("click", function(){
//disable the button to prevent multiple clicks
$("#submitbutton").attr("disabled", "disabled");
var myname = $("#namefield").val();
//perform the request
var req = ocpu.rpc("output", {

document.write(output);

我做了一個
document.write(output)
並將輸出復制到此地址的jsfiddle：
http://jsfiddle.net/gsaray101/rmL1573f/
它在那里工作，所以我假設數據是准確的，有什么想法可能會發生什么？

我通過在ui中使用JSON.parse（）函數解決了此問題，如下所示：
var data=output;
data=JSON.parse(data);
