help me with TEXTAREA!!!

[hackle]

hello buddy,
can you help me with this one?

i wanna insert something into the TEXTAREA, generally we do text.value+="whatever we want";
or
text.value="whatever we want"+text.value;

but that just works to add something to the start or end of the TEXTAREA; what if inside it?
please 🙁

Ummm, this looks like JavaScript? In php:

$NewText="whatever we want";
echo "<textarea>$NewText</textarea>";

I have a feeling your question is really more complex than that, though...given a string value, you'd probably have to first determine a way to determine where the 'new text' should be added.

Feels like a case for strtok() or substr(), perhaps; or maybe ereg_replace if you take a different tack....

got more data?

what i do is pull the stuff i want to edit from the database and display it in a textbox, where i can edit it and then submit it, so it is stored in the database again.

This works in both IE and netscape/mozilla.

<script>
function insertAtCursor(myField, myValue) {
//IE support
if (document.selection) {
myField.focus();
sel = document.selection.createRange();
sel.text = myValue;
}
//MOZILLA/NETSCAPE support
else if (myField.selectionStart || myField.selectionStart == '0') {
var startPos = myField.selectionStart;
var endPos = myField.selectionEnd;
myField.value = myField.value.substring(0, startPos)
+ myValue
+ myField.value.substring(endPos, myField.value.length);
} else {
myField.value += myValue;
}
}
</script>

Example usage: <input type="button" value="Insert Something" onClick="insertAtCursor(document.formName.fieldName, 'something');">
