使用javascript读取Json文件数据？

Question

function uploadJsonFunction(){
  var jsonURL = "C:\Users\My Documents\new\WebContent\JsonFiles\TreeJson\countries.json";
}

• countries.json is valid json and the above path has countries.json file.
• I want to read the countries.json file whole data/contents using javascript.

Here is my Json:

{
  identifier: 'id',
  label: 'name',
  items: [
    {
      id: 'AF',
      name: 'Africa',
      type:'continent'
    }
  ]
}

Answer 1

$.ajax({
    url: "\countries.json",
    success: function (data) {
        var obj = JSON.parse(data);
    }
});

For safety reasons, The C:\\Users\\My Documents\\new\\WebContent\\JsonFiles\\TreeJson\\countries.json url won't work in a browser.

Answer 3

Why not to try Google: http://www.json.org/js.html

I used this for Android app that worked with PhoneGap(HTML+Javascript+JQuery)

Worked fine.

My Method:

var link_name = pathtojson.json

$.getJSON(link_name,
function(data){
var ttext = (data["SearchResponse"]["Translation"]["Results"][0]["TranslatedTerm"]);
document.getElementById('ttexti').innerHTML = ttext;
}
);
