修改地址后的参数：
<skrip>
fungsi getNewUrl(oldurl,paramname,pvalue){
var reg = new RegExp("(\?|&)"+ nama param +"=([^&]*)(&|$)","gi");
var t=oldurl.pertandingan(reg)[0];
var retxt=t.substring(0,t.indexOf("=")+1)+pvalue;
if(t.charAt(t.length-1)=='&') retxt+="&";
kembalikan oldurl.replace(reg,retxt);
}
peringatan(getNewUrl(" http://servername/virturlpath/index.asp?p1=123&p2=aa&p3=hh&p4=1","p4","cxz "));
</skrip>
获取地址参数：
<skrip>
fungsi aa(sumber, nama)
{
var reg = RegExp baru("(^|\?|&)"+ nama +"=([^&]*)( \s|&|$ )", "i");
if (reg.test(source)) mengembalikan RegExp.$2; kembali "";
};
peringatan(aa(" http://community.csdn.net/Expert/topic/4223/4223277.xml?temp=6.502932E-02 ", "temp"))
</skrip>
