PHP json_encode到JS

Question

PHP json_encode as AJAX var "result":

[{"id":"139","assettypeid":"3","name":"skin1","body":"skin1.jpg"}]

I'm trying to access each property, but I can't:

for (var i =0;i < result.length-1;i++)
{
  var item = result[i];
  console.log (item.id + item.name + item.body);
}

All I see is:

NaN
NaN
NaN
NaN
NaN
NaN
NaN
NaN
NaN
...

And there are way too many iterations ... as you can see in the JSON above, there should only be 4 loops.

Answer 1

you need to use JSON.parse

var items = JSON.parse(result)

UPDATE:

I modified my answer to create a JSON call to a server side file like PHP or Ruby. If you are using jQuery try this instead:

$.ajax({
    url: 'http://url-of-your-server-side.com/server-side-file-name.php',
    dataType: 'jsonp',
    jsonp: 'jsoncallback',
    success: function(data) {
        $.each(data, function(i,item){
            console.log (item.id + item.name + item.body);
        });
    error: function(){
        // execute upon failure
    }

Data is the variable that holds your array provided by your ajax request.

Answer 3

for(var item in result){
    console.log(item.id, item.name, item.body);
}
