使用 JavaScript 将 JSON 字符串解析为数组

Question

May seem silly for most of you but I need to parse a JSON string as an array using JavaScript.I'm completely new to JSON and JavaScript and trying to make sense since last two days.

I need to read this JSON as an array and parse it using Javascript. In this example the JSON returned is single element, however in specific cases it returns multiple results(array)

[
  {
    "CauseAndEffect_Status": "InProgress",
    "CurrentPhase": "Planning",
    "cityCountry": "Walker French Southern Territories",
    "location": "bangalore",
    "siteAddress": "Sharon Street Canda Avenue",
    "siteName": "DAISU",
    "status": "95%",
    "zipCode": 12940
  }
]

Although the above JSON is an array object,I get the following error when I try to parse this JSON

SyntaxError: JSON.parse: unexpected character at line 1 column 2 of the JSON data of Jquery-2.1.4.min.js

Answer 1

Code For Parsing Json in Javascript . See the Js Fiddle below

 var str ='{"CauseAndEffect_Status": "InProgress","CurrentPhase": "Planning", "cityCountry": "Walker French Southern Territories","location": "bangalore","siteAddress": "Sharon Street Canda Avenue","siteName": "DAISU","status": "95%","zipCode": 12940}'; var json = JSON.parse(str); console.log(json); $.each( json, function( ky, val ) { console.log('ky => '+ky);//will output: name, firstname, societe console.log('val => '+val);//will output: name1, fname1, soc1 });

CHECK THE BROWSER CONSOLE TO SEE RESULT

If it comes from the server as a string, you can use

var myArray= JSON.parse(myJsonString);

and you you'll have an array of objects myArray which you can cicle with a simple for loop
