//将Form的数据转化成Javascript的Json对象

//Jquery的serializeArray 方法已经可以实现将Form的数据序列化为一个数组，只要稍微在这个方法的基础上做些修改即可。

//方法1：
$.fn.serializeObject = function(){
    var o = {};
    var a = this.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 || '';
        }
    });
}
//方法2：
var data = {};
$("form").serializeArray().map(function(x){data[x.name] = x.value;});

//方法3
var d={};$(form).find('input,select').each(function(){d[this.name]=this.value});console.log(d);

//方法4
var d = {};
var t = $('form').serializeArray();
$.each(t, function() {
    d[this.name] = this.value;
});
alert(JSON.stringify(d));

//清除所有的表单数据 
//可能针对不同的表单形式，你需要调用不同类型的清楚方法，不过使用下面这个现成方法，绝对能让你省不少功夫。
function clearForm(form) {  
  // iterate over all of the inputs for the form
  // element that was passed in
  $(':input', form).each(function() {
    var type = this.type;
    var tag = this.tagName.toLowerCase(); // normalize case
    // it's ok to reset the value attr of text inputs,
    // password inputs, and textareas
    if (type == 'text' || type == 'password' || tag == 'textarea')
      this.value = "";
    // checkboxes and radios need to have their checked state cleared
    // but should *not* have their 'value' changed
    else if (type == 'checkbox' || type == 'radio')
      this.checked = false;
    // select elements need to have their 'selectedIndex' property set to -1
    // (this works for both single and multiple select elements)
    else if (tag == 'select')
      this.selectedIndex = -1; // 0.为第一项 -1.什么都不选择
  });
