Loop through JSON object List

Loop through JSON object List

I am returning a List<> from a webservice as a List of JSON objects. I am trying to use a for loop to iterate through the list and grab the values out of the properties. This is a sample of the returning JSON:

{"d":[{"__type":"FluentWeb.DTO.EmployeeOrder",   "EmployeeName":"Janet Leverling",   "EmployeeTitle":"Sales Representative",   "RequiredDate":"\/Date(839224800000)\/",   "OrderedProducts":null}]}  

So I am trying to extract the contents using something like this:

function PrintResults(result) {    for (var i = 0; i < result.length; i++) {       alert(result.employeename);  }  

How should this be done?

Be careful, d is the list.

for (var i = 0; i < result.d.length; i++) {       alert(result.d[i].employeename);  }

It's close! Try this:

for (var prop in result) {      if (result.hasOwnProperty(prop)) {          alert(result[prop]);      }  }  

Update:

If your result is truly is an array of one object, then you might have to do this:

for (var prop in result[0]) {      if (result[0].hasOwnProperty(prop)) {          alert(result[0][prop]);      }  }  

Or if you want to loop through each result in the array if there are more, try:

for (var i = 0; i < results.length; i++) {      for (var prop in result[i]) {          if (result[i].hasOwnProperty(prop)) {              alert(result[i][prop]);          }      }  }

Since you are using jQuery, you might as well use the each method... Also, it seems like everything is a value of the property 'd' in this JS Object [Notation].

$.each(result.d,function(i) {      // In case there are several values in the array 'd'      $.each(this,function(j) {          // Apparently doesn't work...          alert(this.EmployeeName);          // What about this?          alert(result.d[i][j]['EmployeeName']);          // Or this?          alert(result.d[i][j].EmployeeName);      });  });  

That should work. if not, then maybe you can give us a longer example of the JSON.

Edit: If none of this stuff works then I'm starting to think there might be something wrong with the syntax of your JSON.

Here it is:

success:       function(data) {          $.each(data, function(i, item){              alert("Mine is " + i + "|" + item.title + "|" + item.key);          });      }  

Sample JSON text:

{"title": "camp crowhouse",   "key": "agtnZW90YWdkZXYyMXIKCxIEUG9zdBgUDA"}

I have the following call:

$('#select_box_id').change(function() {          var action = $('#my_form').attr('action');      $.get(action,{},function(response){          $.each(response.result,function(i) {                alert("key is: " + i + ", val is: " + response.result[i]);            });      }, 'json');      });  

The structure coming back from the server look like:

{"result":{"1":"waterskiing","2":"canoeing","18":"windsurfing"}}

var d = $.parseJSON(result.d);  for(var i =0;i
