实现html页面的参数传递参数,javascript实现html页面之间参数传递的四种方法实例分析...

/*

*函数功能：从href获得参数

*sHref: http://www.cscenter.com.cn/arg.htm?arg1=d&arg2=re

*sArgName:arg1, arg2

*return: the value of arg. d, re

*/

function GetArgsFromHref(sHref, sArgName)

{

var args = sHref.split("?");

var retval = "";

if(args[0] == sHref) /*参数为空*/

{

return retval; /*无需做任何处理*/

}

var str = args[1];

args = str.split("&");

for(var i = 0; i < args.length; i ++)

{

str = args[i];

var arg = str.split("=");

if(arg.length <= 1) continue;

if(arg[0] == sArgName) retval = arg[1];

}

return retval;

}

方法二：

function getvalue(name)

{

var str=window.location.search;

if (str.indexOf(name)!=-1)

{

var pos_start=str.indexOf(name)+name.length+1;

var pos_end=str.indexOf("&",pos_start);

if (pos_end==-1)

{

return str.substring(pos_start);

}

else

{

return str.substring(pos_start,pos_end)

}

}

else

{

return "没有这个name值";

}

}

alert(getvalue(name));
