I have tried to make it so that if the user types in some text into an input field it gives them their text backwards in a textfield.
here is my code so far:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" />
<title></title>
</head>
<body>
<script type="text/javascript">
function enablesubmit() {
document.getElementById("submit").disabled=false;
}
function generatetext() {
var textinfo=document.getElementById("textinput").value;
for(i=textinfo.length;) {
var textinfo2=textinfo(charAt(1));
}
document.getElementById("codeplace").value=textinfo2;
document.getElementById("submit").disabled=true;
}
document.write('<input type="text" id="textinput" onkeydown="enablesubmit()" />');
document.write('<input type="submit" id="submit" onclick="generatetext()" value="Change" disabled="true" />')
document.write('<br /><br />');
document.write('<textarea id="codeplace"></textarea>');
</script>
</body>
</html>
Only it doesn't display...
for(i=textinfo.length;)
...
A quick way to reverse a string:
myString = myString.split("").reverse().join("");
<body>
<script type="text/javascript">
function enablesubmit() {
document.getElementById("submit").disabled=false;
}
function generatetext() {
var textinfo=document.getElementById("textinput").value;
var textinfo2 = texinfo2.split("").reverse().join("");
document.getElementById("codeplace").value=textinfo2;
document.getElementById("submit").disabled=true;
}
document.write('<input type="text" id="textinput" onkeydown="enablesubmit()" />');
document.write('<input type="submit" id="submit" onclick="generatetext()" value="Change" disabled="true" />')
document.write('<br /><br />');
document.write('<textarea id="codeplace"></textarea>');
</script>
</body>
</html>
Doesn't seem to go.
var textinfo=document.getElementById("textinput").value;
var textinfo2 = texinfo2.split("").reverse().join("");
Try reading the error messages from the browser your are testing with.
