How do I insert a character at the caret with javascript?

I want to insert some special characters at the caret inside textboxes using javascript on a button. How can this be done?

The script needs to find the active textbo

Answer 1

loop over all you input fields... finding the one that has focus.. then once you have your text area... you should be able to do something like...

myTextArea.value = 'text to insert in the text area goes here';
