使用jQuery生成JSON

Question

I have 4 inputs in a form:

<form id="mark_date_form">
   <input type="text" name="title" class="form-control" placeholder="Title" value="motherday">
   <input type="text" name="date" class="form-control datepick" placeholder="MM/DD" value="05/13">

   <input type="text" name="title" class="form-control" placeholder="Title" value="fatherday">
   <input type="text" name="date" class="form-control datepick " placeholder="MM/DD" value="06/18">
</form>

When I use $('#mark_date_form').serializeArray() in jQuery, it returns

[
    {
        "name": "title",
        "value": "motherday"
    },
    {
        "name": "date",
        "value": "05/13"
    },
    {
        "name": "title",
        "value": "fatherday"
    },
    {
        "name": "date",
        "value": "06/18"
    }
]

The question is I have to come out with something like this:

[
    {
        "title": "motherday",
        "date": "05/13"
    },
    {
        "title": "fatherday",
        "date": "06/18"
    }
]

What should be the jQuery looks like?

Thank you very much!

Answer 1

I think you are looking for this $("#mark_date_form").serialize() ;

Update: sorry for the @daniel-cai is correct. Use $("#mark_date_form").serializeArray(); for getting JavaScript literal object.

Answer 2

You can use this:

var a = [];
$('#mark_date_form input').each(function(){
    if($(this).attr('name')=='title'){
        a.push({"title":$(this).val(),"date":$(this).next().val()});
    }
});
console.log(a);

Output:

[Object { title="motherday",  date="05/13"}, Object { title="fatherday",  date="06/18"}]

Answer 3

Simple way to get a json file as you want is:

var o = {};
$("#mark_date_form").serializeArray().map(function(x){o[x.name] = x.value;}); 
console.log(o);

Result:

Object {title: "motherday", date: "05/13"}
