    Here is modified version of above plugin:

    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();
        }
      })
    }
    });
    

    Basically, this plugin allows you to insert a piece of text at caret of multiple textbox or textarea . You can use it like this:

     $('#element1, #element2, #element3, .class-of-elements').insertAtCaret('text');
