JavaScript - Building JSON object
- by user208662
Hello,
I'm trying to understand how to build a JSON object in JavaScript. This JSON object will get passed to a JQuery ajax call. Currently, I'm hard-coding my JSON and making my JQuery call as shown here:
$.ajax({
url: "/services/myService.svc/PostComment",
type: "POST",
contentType: "application/json; charset=utf-8",
data: '{"comments":"test","priority":"1"}',
dataType: "json",
success: function (res) {
alert("Thank you!");
},
error: function (req, msg, obj) {
alert("There was an error");
}
});
This approach works. But, I need to dynamically build my JSON and pass it onto the JQuery call. However, I cannot figure out how to dynamically build the JSON object. Currently, I'm trying the following without any luck:
var comments = $("#commentText").val();
var priority = $("#priority").val();
var json = { "comments":comments,"priority":priority };
$.ajax({
url: "/services/myService.svc/PostComment",
type: "POST",
contentType: "application/json; charset=utf-8",
data: json,
dataType: "json",
success: function (res) {
alert("Thank you!");
},
error: function (req, msg, obj) {
alert("There was an error");
}
});
Can someone please tell me what I am doing wrong? I noticed that with the second version, my service is not even getting reached.
Thank you
