JScript string.replace方法一次只替换一个，比较麻烦，有没有好的办法一次全部替换完了

<SCRIPT LANGUAGE="JavaScript">
var aa="aabbccaabbccaabbccaabb";
var cc = aa.replace('aa','bb');
alert (cc);
</SCRIPT>

精典，
我自己写的

function Replace(strPar,f,s) {
var sTemp = (strPar == null) ? '': strPar.toString() ;
while (sTemp.indexOf(f) != -1) sTemp = sTemp.replace(f,s) ;
return sTemp ;
}
还是 qiushuiwuhen(秋水无恨) 的好，谢！

<SCRIPT LANGUAGE="JavaScript">

var cc = aa.replace(/aa/g,'bb');
alert (cc);
</SCRIPT>

function replace(str,replace_what,replace_with)
{
var ndx=str.indexOf(replace_what);
var delta=replace_with.length - replace_what.length;
while(ndx >= 0)
{
str=str.substring(0,ndx)+replace_with+str.substring(ndx+replace_what.length);
ndx=str.indexOf(replace_what,ndx+delta+1);
}
return str;
}
var aa="aabbccaabbccaabbccaabb";
var cc=replace(aa,"aa","bb");
alert(cc)
