js序列化数组用于ajax提交数据

//这里只能处理二维数组数据,多维的需在做循环或递归
function serialize_data(obj){
    var str = ‘‘;
    for(var i in obj){
        if(typeof(obj[i]) === ‘object‘){
            for(var s in obj[i]){
                str = str + i+‘[‘+ s + ‘]‘ + ‘=‘ + obj[i][s] + ‘&‘;
            }
        }else{
            str = str + i + ‘=‘ + obj[i] + ‘&‘;
        }
    }
    return encodeURI(str);
}
