应用场景： jquery + ajax 表单提交，一次性获取所有表单，并解析到post 参数
常用点 1 ：
//获取所有表单参数： 结果格式为： a=1&b=2&c=3
$('form').serialize();
常用点 2 ：jquery 解析 url参数
//封装方法
(function($) {
var re = /([^&=]+)=?([^&]*)/g,
decodeRE = /+/g,
decode = function (str) { return decodeURIComponent( str.replace(decodeRE, " ") ); };
$.parseParams = function(query) {
let params = {}, e;
while ( e = re.exec(query) ) params[ decode(e[1]) ] = decode( e[2] );
return params;
};
})(jQuery);
//使用方法 ：
var formdata = 'a=1&b=2&c=3';
var json_data = $.parseParams(formdata); //json_data 格式 : {a:1,b:2,c:3}
