Adding Text to Textarea.

[phpSensei]

<script type="text/javascript">
function smiley(tag)
{
var emo=document.forms["form"].elements["message"];
emo.value+=""

}
</script>

 

the code works perfectly, but everytime you put a text into the field, it goes at the end of the string, not where the cursor is.

 

help please.

here is the replaceText function that this forum uses. It is not perfect but should suit your needs.

 

function replaceText(text, textarea)
{
// Attempt to create a text range (IE).
if (typeof(textarea.caretPos) != "undefined" && textarea.createTextRange)
{
	var caretPos = textarea.caretPos;

	caretPos.text = caretPos.text.charAt(caretPos.text.length - 1) == ' ' ? text + ' ' : text;
	caretPos.select();
}
// Mozilla text range replace.
else if (typeof(textarea.selectionStart) != "undefined")
{
	var begin = textarea.value.substr(0, textarea.selectionStart);
	var end = textarea.value.substr(textarea.selectionEnd);
	var scrollPos = textarea.scrollTop;

	textarea.value = begin + text + end;

	if (textarea.setSelectionRange)
	{
		textarea.focus();
		textarea.setSelectionRange(begin.length + text.length, begin.length + text.length);
	}
	textarea.scrollTop = scrollPos;
}
// Just put it on the end.
else
{
	textarea.value += text;
	textarea.focus(textarea.value.length - 1);
}
}

 

You can use it like this

 

<a onclick="replaceText('your_text', document.getElementById('your_textarea'); return false;">Some Text</a>

 

good luck

<a onclick="replaceText(''), document.getElementById('message'); return false;"><img src="../admin/happy.gif" alt="" width="18" height="24"></a>

 

Am I suposed to change anything else than the ElementbyId('message') or....

 

Thanks for the support though..

 

It doesnt work because I have never used javascript so much, just pure php.
