js将form表单序列化[json字符串、数组、对象]

    function getFormJson(form) {
        var o = {};
        var a = $(form).serializeArray();
        $.each(a, function () {
            if (o[this.name] !== undefined) {
                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 deleteNum= [];//定义要传递的数组
deleteNum.push("1");
deleteNum.push("2");
deleteNum.push("3");//向数组中添加元素

$.ajax({
    type:"post",
    url:"deleteNum.do",
    data:{deleteNum:deleteNum},
    traditional: true,//必须指定为true
    success:function(data){
        if(data.success){
            deleteNum = [];
        }
    }
});

public AjaxResult deleteNum(String[] deleteNum){
    AjaxResult ajaxResult = new AjaxResult();
    //这个时候已经得到了deleteNum数组值
    return ajaxResult;
}
