intercept paste and do formatting in JavaScript (in Angular.js)

paste.js

// tested in Chrome and Firefox
this.onPaste = function (event) {
  if($(event.target).is(':focus')) {
    // actually typing on the element, stop paste progation to outside paste handler
    event.stopPropagation();

    // intercept paste and format the text
    event.preventDefault();
    var newText = (event.originalEvent || event).clipboardData.getData('text/plain');
    newText = newText.replace(/\r?\n/g, ' ');
    // merged the newly pasted text with original text
    var el = $(event.target);
    var cursorPosStart = el.prop('selectionStart');
    var cursorPosEnd = el.prop('selectionEnd');
    var v = el.val();
    var textBefore = v.substring(0, cursorPosStart);
    var textAfter  = v.substring(cursorPosEnd, v.length);
    var mergedText = textBefore + newText + textAfter;
    // insert text manually by updating model to trigger msd-elastic directive
    self.fieldModel = mergedText;
    // move cursor to correct position after paste
    $timeout(function(){
      el[0].selectionStart = el[0].selectionEnd = cursorPosStart + newText.length;
    });
  }
};
