I've been making good use of the asp javascript replace function (something.replace("this","that". but so far I can only replace the first instance of a string and can only replace exact case sensitive matches.

Using regular expressions I've been able to do a replace all, but not when i want to do something like replace all the hello's (or HeLlO's) with goodbyes's etc.

Can this be done?

try this:

<pre id=code><font face=courier size=2 id=code>
var string1 = "hello my name is bob. Hello bob. heLLO my name is kate HELLO kate"

var string2 = replaceAll(string1,"Hello","goodbye",false)
Response.Write("string 1 = " [add] string1)
Response.Write("&lt;br&gt;"
Response.Write("string 2 = " [add] string2)

function replaceAll(strSource,lookFor,replaceWith) {
strLowerCase = strSource.toLowerCase();
lookForLower = lookFor.toLowerCase();
while(strLowerCase.indexOf(lookForLower) != -1) {
posStart = strLowerCase.indexOf(lookForLower)
posEnd = posStart [add] lookFor.length
strLowerCase = strLowerCase.substring(0,posStart) [add] replaceWith [add] strLowerCase.substring(posEnd,strLowerCase.length)
strSource = strSource.substring(0,posStart) [add] replaceWith [add] strSource.substring(posEnd,strSource.length)

}
return strSource
}

</font id=code></pre id=code>

replace [add] with plus sign.

This will replace all the instances of 'hello' with 'goodbye' but will not preserve the case.

p.s. How do we write a plus sign in code in these forums?
