Hi,
I need some help with this code. I want to make all the small letters to big and all the big letters to small letters. After that I want to make the letter "A" become an "#".
It should look something like this:
This Is a Text
tHIS iS a tEXT
This is # Text
This is the code I currently work one:
var str = "This Is a Text"
if(str.toLowerCase == str) {
document.write(str.toUpperCase())
document.write("<br />")
}
if(str.toUpperCase == str) {
document.write(str.toLowerCase())
document.write("<br />")
}
I am completely lost and need help or advice. Thanks!
Use Regular Expressions:

I've updated the code a bit:
var str = "This Is a Text"
if(str.toLowerCase == str) {
str = str.toUpperCase();
str = str.replace('A', '#');
document.write(str);
document.write("<br />");
}
But it still has problems. Nothing is written onto the page! :confused:

With respect to Kor, I don't see how regex will help here except for
str = str.replace('A', '#');
Here's what I have done so far, but still needs finishing off.
<SCRIPT type="text/javascript">
var str = "Hello world!"
var flag = 0;
var str1 = ""
var a = new Array();
for (var j=0; j<str.length; j++) {
flag = 0; // reset the flag
a[j] = (str.charCodeAt(j));
if (a[j] >= 65 && a[j] <=90) {
a[j] = a[j] + 32; // change upper case letter A-Z to lower case
flag = 1; // set the flag
}
if (flag==0) { // only if flag not set
if (a[j] >=97 && a[j] <=122) { // change lower case letter a-z to upper case
a[j] = a[j] - 32;
}
}
a[j] = "%" + a[j] // add % sign
str1 = str1 + a[j] //concatenate
alert (str1);
}
</script>
