JavaScript JSON object not parsing

Question

Here's my JS code from a success section of an AJAX call:

success: function(msg){
    var data = JSON.parse(JSON.stringify(msg));
    $("#searchResults").html(data + " Value for 'a': " + data.color + "\nValue for 'b': " + data.message);
}

Here's what's printed on the page:

{"color":"Yellow","message":"Pending"} Value for 'a': undefined Value for 'b': undefined

Why are they undefined?

Answer 1

console.log data似乎仍然是字符串，如@Musa所说，您需要删除JSON.stringify

Answer 2

If your ajax response is JSON you should explicitly state so in the request so that it will be parsed automatically for you by jQuery.ajax . dataType: 'json'

$.ajax({
...
    dataType: 'json',
    success: function(data){
        $("#searchResults").html(" Value for 'a': " + data.color + "\nValue for 'b': " + data.message);
    }
...
