Converting serialized form data into json object using Jquery?

Question

I am trying to get data from my form and then send it to a servlet. But then I notice that the json object that I am getting after serializing my form is not a valid json object. What could I be doing wrong? This is what I tried so far.

<script type="text/javascript">
$(document).on("click", "#check", function() { // When HTML DOM "click" event is invoked on element with ID "somebutton", execute the following function...
      event.preventDefault();
      var data = $("#register").serialize().split("&");
      var obj={};
        for(var key in data)
        {
            console.log(data[key]);
            obj[data[key].split("=")[0]] = data[key].split("=")[1];
        }

        console.log(obj);
// store json string
     $.ajax({
            type: "POST",
            url: "HomeServlet",
            dataType: "text",
            contentType: "application/json",
            data:{"res":obj},
            success: function(data){
                console.log(data);
            },
            error:function(){
                console.log("error");
            },

        });
});

</script>

The json object that i am getting from the form is -

{
    apiname: "jdjdj",
    apiendpoint: "sdjsdj",
    apiversion: "djdjd",
    source: "internet"
}

This is what I want -

{
    "apiname": "jdjdj",
    "apiendpoint": "sdjsdj",
    "apiversion": "djdjd",
    "source": "internet"
}

Answer 1

There is nothing wrong with the json you Got .

Just stringify it to get the desired object

var myJSON1 = JSON.stringify(data);

this will work

Answer 2

你可以试试看

JSON.stringify(json_data);

Answer 3

As others have noted, your passing a raw javascript object. What you must do is convert this object prior to sending it over the wire.

JSON.stringify(json_data);

Answer 4

Instead of this foreach loop only use serializeArray() then json_parse() these two functions will work for you.

var data = $("#register").serializeArray();
var obj= JSON_parse(JSON_stringify(data));

Answer 5

请使用JSON.stringify(obj, undefined, 2);
