常见获取参数和表单序列化的方法

//获取url参数
function urlParam(name){
var results = new RegExp('[?&]' + name + '=([^&#]*)').exec(window.location.href);
if (results==null){
return null;
}
else{
return results[1] || 0;
}
}
//
//form to json
$.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;
}

//json转url参数
var parseParam = function(param, key) {
var paramStr = "";
if (param instanceof String || param instanceof Number || param instanceof Boolean) {
paramStr += "&" + key + "=" + encodeURIComponent(param);
} else {
$.each(param, function(i) {
var k = key == null ? i : key + (param instanceof Array ? "[" + i + "]" : "." + i);
paramStr += '&' + parseParam(this, k);
});
}
return paramStr.substr(1);
};
