Question

i have a Json result that i got through a webservice, now i want to see if it works, how do i make that Json values show in a button or link? and on page load?

one of the values returned looks like this : “name”: “Muhammad Ali”,
“nickname”: “The Greatest”,

very new to json and javcascript.

Javascript and json :

    function Getdata() {
    $.ajax({
        type: "POST",
        data: "{}",
        url: "https://raw.github.com/appcelerator/Documentation-Examples/master/HTTPClient/data/json.txt",
        contentType: "application/json; cherset=utf-8",
        datatype: "json",
        success: loadpage,
        failure: givealert
    });



    function loadpage(result) {
        if (resu.hasOwnProperty("d")) { result = res.d; }
        var data = JQuery.parseJSON(result);
    }

    function givealert(error) {
        alert('failed!!' + error);
    }
}

now how do i get it to show one value from the web-service in a label and on form load?
html markup for the label/button :

 <div id="listheight">
                <a type="button" id="routing" href="#datatapage"></a>
            </div>

i am using cordova/phonegap,Visual studi2010, html, javascript, css, jquerymobile and jquery1.8.2.

thanks in advance!

Answer 1

First, use this HTML

<a type="button" id="routing" href="#datatapage" onclick="Getdata()">Click</a> 

Use this code to call the method automatically on pageload

$(document).ready(function() {
  // this is executed on page load
  Getdata();
});

and change your code to

jQuery.support.cors = true;

function Getdata() {
  var request = $.ajax({
    type: "POST",
    data: "{}",
    dataType: 'json',
    url: "data/json.txt",  // better use a relative url here
    mimeType: "application/json; cherset=utf-8",
    success: loadpage,
    failure: givealert
  });

  function loadpage(result) {
    // this only displays you the values in a messagebox for you to check if it works
    // you can remove the following two lines
    alert("Name = "+result.fighters[0].name);
    alert("Nickname = "+result.fighters[0].nickname);
    // this changes the text
    document.getElementById("routing").innerHTML = result.fighters[0].name;
  }

  function givealert(error) {
    alert('failed!!' + error);
  }
}

I created a JSFiddle for this: http://jsfiddle.net/FUWyJ/
