I have multiple TEXTAREA and BUTTON out side.. For inserting string in textarea, I used jQuery plugin (insertAtCaret). How to fill ONLY the last clicked TEXTAREA with text…?

<textarea name="answer_text[0]" cols="50" rows="3" style="width: 99%;">
    AAA
</textarea>

<textarea name="answer_text[1]" cols="50" rows="3" style="width: 99%;">
    BBB
</textarea>

<textarea name="answer_text[2]" cols="50" rows="3" style="width: 99%;">
    CCC
</textarea>

<textarea name="answer_text[3]" cols="50" rows="3" style="width: 99%;">
    Here should be:
    &lt;button class=insert name=insert&gt;Insert&lt;/button&gt; 
</textarea>

<button class=insert name=insert>Insert</button>

<script type="text/javascript">
jQuery.fn.extend({
insertAtCaret: function(myValue) {
    return this.each(function(i) {
        if (document.selection) {
            //For browsers like Internet Explorer
            this.focus();
            sel = document.selection.createRange();
            sel.text = myValue;
            this.focus();
        }
        else if (this.selectionStart || this.selectionStart == '0') {
            //For browsers like Firefox and Webkit based
            var startPos = this.selectionStart;
            var endPos = this.selectionEnd;
            var scrollTop = this.scrollTop;
            this.value = this.value.substring(0, startPos) + myValue + this.value.substring(endPos, this.value.length);
            this.focus();
            this.selectionStart = startPos + myValue.length;
            this.selectionEnd = startPos + myValue.length;
            this.scrollTop = scrollTop;
        } else {
            this.value += myValue;
            this.focus();
        }
    });
}
});

var pos = 0;
$('textarea').click(function() {
//Get the name of this clicked item
var pos = $(this).attr("name");
$('.insert').click(function() {
    $('textarea[name^="' + pos + '"]').insertAtCaret('Actual button code');
});
return false;
});
</script>

Now I getting filed all the textareas that I clicked… http://jsfiddle.net/ArtofLife/u9d9d/15/

I want to be filled only the last textarea that is clicked, and not bubbling the variable pos..

It is because you have the .insert‘s click handler inside the textarea click handler. Whenever you click on textarea a new handler is attached and it keeps attaching as and when u click on any textarea. Move it outside it will work fine.

var pos = 0;
$('textarea').click(function() {
    //Get the name of this clicked item
    pos = $(this).attr("name");
    return false;
});
$('.insert').click(function() {
    $('textarea[name^="' + pos + '"]').insertAtCaret('Actual button code');
});
