在flash中有个变量kk="12345abc.123";
请问怎么写AS使“123”替换为“321”，“abc”替换为“efg”
替换后的新字符串为tt
trace(tt) |
方法1：
kk="12345abc.123";
kk = replace(kk,"123","321");
trace(kk);
function replace(str, find ,replace) {
var counter = 0;
while (counter<str.length) {
var start = str.indexOf(find, counter);
if (start == -1) {
break;
} else {
var before=str.substr(0,start)
var after=str.substr(start+find.length,str.length)
str=before+replace+after
var counter=before.length+replace.length
}
}
return str;
}
方法2：
kk="12345abcabcabc.123";
ww=cs(kk,"ab","-");
trace(ww);
function cs(ya,ta,ea){
md=ya.split(ta);
trace(md.length);
if(dd.length==1 and ta != ea){
return "no String";
break;
}else{
mystring="";
for(j=0;j<md.length-1;j++){
mystring=mystring.concat(md[j].concat(ea));
}
mystring=mystring.concat(md[md.length-1]);
return mystring;
}
