take first letter out of a form-tag
what i'd like to do:
i have an
-tag. when the user writes something in it, it takes the first letter out (without deleting it, of course) and puts it somewhere on a specified area on the page.
for example:
it takes the 'w' out of my message-field and puts it on the very top of the page.
i think this shoud be doable? any ideas?

when would you take the letter out? onBlur? onChange? onClick?
anyway.... I used onClick with a button
<html><head>
<script language=javascript>
function do_sumthin() {
tmp = my.value;
blah.innerHTML=blah.innerHTML + tmp.substring(0,1);
my.value=tmp.substring(1,tmp.length)
}
</script>
</head>
<body>
<span id=blah></span>
<BR>
<input type=text id=my>
<input type=button value="Send it away!" onClick="do_sumthin()">
</body>
</html>

If there is no answer on Google, then there is no question.

thanks, mark.
but i get an error:
'my' is not defined...
another question: what's the span-tag for?
i need the whole thing onChange but that i can do on my own (at least one thing!
)

I'm using IE5 and it works for me. Try stuff like document.my.value or put it in a form and try form_name.my.value
the span tag... notic the ID property? I use it later to put the text from the textbox into the HTML page. The innerHTML is used to address the text between the span tags. Here, I added to it with each click.

To write to layers in netscape, you must use layername.document.write. Try this:
<html><head>
<script language=javascript>
function do_sumthin() {
tmp = my.value;
if (document.layers){
document.layers[blah].document.open();
document.layers['blah'].document.write(blah.innerHTML + tmp.substring(0,1));
document.layers['blah'].document.close();
}
else{
document.all['blah'].innerHTML=blah.innerHTML + tmp.substring(0,1);
my.value=tmp.substring(1,tmp.length)
}
}
</script>
</head>
<body>
<span id=blah></span>
<BR>
<input type=text id=my>
<input type=button value="Send it away!" onClick="do_sumthin()">
</body>
</html>

still not working in nn.
). my last try:
i tried it with quite a lot of possibilities of combinations (what shall i do, don't know java...
function takeoutfirstletter() {firstletter.innerHTML = "";
tmp = document.wettbewerb.titel.value;
if (document.layers){
document.layers['firstletter'].document.open();
document.layers['firstletter'].document.write(firstletter.innerHTML + tmp.substring(0,1));
document.layers['firstletter'].document.close();
} else {
document.all['firstletter'].innerHTML = firstletter.innerHTML + tmp.substring(0,1);
titel.value=tmp.substring(1,tmp.length)
}
}
got errors from 'takeoutfirstletter' not defined via 'document.all' has no properties to firstletter not defined.
any ideas what i'm doing wrong here?

You can't use firstletter.innerHTML in the document.layers section. NN won't recognize that.
Also, move the first line of the function into else{}.
NS6 has a different way of dealing with layers. This won't work in NS6.
Good luck on the rest
.
Jon.
