How to insert text into TextArea at the cursor position using Javascript?

Hi,
I am trying to insert text into TextArea box dynamically at the cursor position. I can append to the end but I am looking for some kind of Javascript to insert at cursor position.

Thanks,
Grace

you need to get the caret position in the textArea control and insert your text.

Try this Javascript function:

<script type="text/javascript">
function InsertCodeInTextArea(textValue) {
//Get textArea HTML control
var txtArea = document.getElementById("txtTextArea");

//IE
if (document.selection) {
txtArea.focus();
var sel = document.selection.createRange();
sel.text = textValue;
return;
}
//Firefox, chrome, mozilla
else if (txtArea.selectionStart || txtArea.selectionStart == '0') {
var startPos = txtArea.selectionStart;
var endPos = txtArea.selectionEnd;
var scrollTop = txtArea.scrollTop;
txtArea.value = txtArea.value.substring(0, startPos) + textValue + txtArea.value.substring(endPos, txtArea.value.length);
txtArea.focus();
txtArea.selectionStart = startPos + textValue.length;
txtArea.selectionEnd = startPos + textValue.length;
}
else {
txtArea.value += textArea.value;
txtArea.focus();
}
}
</script>


There is specific logic for IE and most of the browsers. This Javascript function takes in text to be inserted into TextArea box. I hope this helps.

Hi Sandhya,
Can you please explain your question? Technically you can not display textbox within the textbox.
