hi there i am making a scrap book application in which i have to populate the smilies as soon as they are written now i am using the textarea to write the input text for the scrap currently i am trying to just achieve it so i am using only 2 smilies but i am not getting it right here is my code -
<script type="text/javascript" language="javascript">
-
var prev="";
-
function emticn(){
-
if(document.getElementById('scrap').value!=""){
-
var txt=document.getElementById('scrap').innerHTML;
-
prev=txt;
-
var replaced=prev.replace(":)","<img src='goggle.gif' alt=':)' />");
-
document.getElementById('scrap').innerHTML=replaced;
-
}
-
-
}
-
</script>
-
-
<body onload="document.getElementById('scrap').focus();">
-
Original:<textarea rows="7" onkeyup="emticn();" name="scrap" id="scrap"></textarea>
-
<div id="resdiv"></div>
-
</body>
-
the error code that i am recieving is "unknown runtime error on line 13 "
which is the javascript line -
document.getElementById('scrap').innerHTML=replaced;
-
which i think is because i am using innerHTML to populate the image tag inside the textarea and if i use the property .value instead of ".innerHTML"
then it does not give me error but infact it does not show me the image but he source code of that image that is -
<img src='goggle.gif' alt=':)'>
-
can somebody help me in this regard that what approach should i use and if ia m going he right way to accomplish this thing
regards,

Use execCommand with iframes. See the test page for an example.
I am guessing part of the problem is that this line :
Should be :

it is not an error it is just a typo mistake here on the forum , whereas in my code it is written like

Well, it's not going to work with the code you've got.
You could, however, create a preview pane (e.g. a div) which could display the smilies that you type in the textarea.

yeah ihave done that already and for that same purpose i have made that "resdiv"
i just omitted that part of code and changed the line -
document.getElementById('resdiv').innerHTML=replaced;
-
TO
-
document.getElementById('scrap').innerHTML=replace d;

because i wanted to populate the emoticons in the text field but it doesnot seem to be possible, but on the other hand if you see my javascript code there is still a problem in it even if i use the div for the preview,it just makes each emoticon work once means,
if i enter :) for the first time then it is ok,it populates the icon for this smiley but if i again write :) it shows it as is does not populate it again same is the case for all other smilies i hope i amnot confusing you,
thanks for any help in advance,

That's probably because you have ":)" as an alt attribute for the emoticon, so that is what's being replaced!

nah em sorry that isnt it i have tried it too it will go to the alt=':)' only if the image is not found or loaded,that didnt solved the problem
No, I meant the text contains :) when you replace :) with an emoticon. See this code: - <img src='goggle.gif' alt=':)'>
The alt attribute has the :) contained within it. When you replace ":)", it may be replacing the alt text rather than the second ":)".
Can you show some demonstrable code which can be tested.

Use value instead of innerHTML and your code should work - I see you've removed the alt.
