How to remove characters from strings?

A function?

[gerryw]

Hi all,
I am fairly new to javaScript and I am trying to write the code which removes a character/s from a string/s. As an example, if I initialise a variable 'myString' and use 'window.prompt' to input the string/s 'Weather' or 'Have a nice day', what would be the javaScript code to return the result (using 'document.write') 'Wthr' or 'ae a ie a'?

Regards

Welcome to WebmasterWorld!

There is some great information on Regular Expressions here: [regular-expressions.info...]
Based on that, this is what a script like that would look like. You can toggle the

useOnlyVowels

variable...

<script type="text/javascript"> 
useOnlyVowels = true; 
myText = "Weather"; 
noVowels = /[aeiou]/ig; 
onlyVowels = /[^aeiou ]/ig; 
if(useOnlyVowels) { 
  myText = myText.replace(onlyVowels,""); 
} 
else { 
  myText = myText.replace(noVowels,""); 
} 
document.write(myText); 
</script>
