使用jquery将表单自动封装成json对象 /json对象元素的添加删除和转换

$.fn.serializeObject = function () {
        var o = {};
        var a = this.serializeArray();
        $.each(a, function () {
            if (o[this.name]) {
                if (!o[this.name].push) {
                    o[this.name] = [o[this.name]];
                }
                o[this.name].push(this.value || '');
            } else {
                o[this.name] = this.value || '';
            }
        });
        return o;
    };
var formData = $("#editForm").serializeObject();

var json={
   id:"id1",
   name:"开心"
};
 
//添加
json["gender"]="男"
json["age"]=26;
alert(json.age);
 
//删除
delete json["age"];
alert(json.age);
alert(json.gender);

$.fn.serializeObject = function () {
        var o = {};
        var a = this.serializeArray();
        $.each(a, function () {
            if (o[this.name]) {
                if (!o[this.name].push) {
                    o[this.name] = [o[this.name]];
                }
                o[this.name].push(this.value || '');
            } else {
                o[this.name] = this.value || '';
            }
        });
        return o;
    };
