I am working on a text replacement page, and I need a bit of help. I want to condense text with javascript. I am using something like this:

var str="at to too"
document.write(str.replace(/at/i,"@"));

This works fine, but I want to replace the to and too in the text also. Any ideas how I could do this?

Code:

var str = "at to too";
var str = str.replace(/at/i, "@");
document.write( str.replace(/t(o){1,2}/g, "place replacetext here"));

This seemed to do the trick.

Basically, the second replace function is matching only to and too. This matches a single 't' literal and either one or two 'o' literals.

Ahh, hadn't thought of that. Makes total sense. Thanks for that!
Alright, one more problem...

Here is the code:

Code:

<html>
<head>
<script type="text/javascript">

function condense() {
var str=document.input.inputfield.value;
str = str.replace(/at/i,"@")
str = str.replace(/to/i,"2")
str = str.replace(/too/i,"2")
str = str.replace(/tommorow/i,"2morrow")
str = str.replace(/you/i,"u")
str = str.replace(/ok/i,"k")

document.output.outputfield.value=(str);
}
</script>
</head>
<body>


<form name="input">
<label>Input:</label>
<br />
<textarea rows="10" cols="30" name="inputfield"></textarea>
<br />
<button onClick=condense();>Condense!</button>
</form>
<form name="output">
<label>Output:</label>
<br />
<textarea rows="10" cols="30" name="outputfield"></textarea>
</form>


</body>
</html>

It quickly dispays what I want in the output field, and then refreshes and disappears... Any ideas?

Thanks,

the problem is you've put it in forms
forms automaticly refresh the webpage
UNLESS you put the form action as "javascript:;"
so the ending code needs to be

Code:

<html>
<head>
<script type="text/javascript">

function condense() {
var str=document.input.inputfield.value;
str = str.replace(/at/i,"@")
str = str.replace(/to/i,"2")
str = str.replace(/too/i,"2")
str = str.replace(/tommorow/i,"2morrow")
str = str.replace(/you/i,"u")
str = str.replace(/ok/i,"k")

document.output.outputfield.value=(str);
}
</script>
</head>
<body>


<form name="input" action="javascript:;">
<label>Input:</label>
<br />
<textarea rows="10" cols="30" name="inputfield"></textarea>
<br />
<button onClick=condense();>Condense!</button>
</form>
<form name="output" action="javascript:;">
<label>Output:</label>
<br />
<textarea rows="10" cols="30" name="outputfield"></textarea>
</form>


</body>
</html>
