JavaScript自定义函数

js对象转成用&拼接的请求参数(转)

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);
};
 
 
 
 
 
var obj={name:'tom','class':{className:'class1'},classMates:[{name:'lily'}]};
parseParam(obj);
结果:"name=tom&class.className=class1&classMates[0].name=lily"
parseParam(obj,'stu');
结果:"stu.name=tom&stu.class.className=class1&stu.classMates[0].name=lily"

 

获取URL中参数对应的值

function GetUrlParam(paraName) {
    var url = document.location.toString();
    var arrObj = url.split("?");

    if (arrObj.length > 1) {
        var arrPara = arrObj[1].split("&");
        var arr;

        for (var i = 0; i < arrPara.length; i++) {
            arr = arrPara[i].split("=");

            if (arr != null && arr[0] == paraName) {
                return arr[1];
            }
        }
        return "";
    }
    else {
        return "";
    }
}

 

获取Cookie中参数对应的值

function GetCookie(c_name)
{
    if (document.cookie.length>0)
    {
        c_start=document.cookie.indexOf(c_name + "=")
        if (c_start!=-1)
        {
            c_start=c_start + c_name.length+1
            c_end=document.cookie.indexOf(";",c_start)
            if (c_end==-1) c_end=document.cookie.length
            return unescape(document.cookie.substring(c_start,c_end))
        }
    }
    return ""
}

 

Date的时间格式函数

Date.prototype.Format = function(fmt)
{ //author: meizz
    var o = {
        "M+" : this.getMonth()+1,                 //月份
        "d+" : this.getDate(),                    //
        "h+" : this.getHours(),                   //小时
        "m+" : this.getMinutes(),                 //
        "s+" : this.getSeconds(),                 //
        "q+" : Math.floor((this.getMonth()+3)/3), //季度
        "S"  : this.getMilliseconds()             //毫秒
    };
    if(/(y+)/.test(fmt))
        fmt=fmt.replace(RegExp.$1, (this.getFullYear()+"").substr(4 - RegExp.$1.length));
    for(var k in o)
        if(new RegExp("("+ k +")").test(fmt))
            fmt = fmt.replace(RegExp.$1, (RegExp.$1.length==1) ? (o[k]) : (("00"+ o[k]).substr((""+ o[k]).length)));
    return fmt;
}
