一套前端设计语言和基于React的实现

'use strict';

Object.defineProperty(exports, "__esModule", {
  value: true
});

exports['default'] = function () {
  var selection = document.getSelection();
  if (!selection.rangeCount) {
    return _noop2['default'];
  }

  var active = document.activeElement;

  var ranges = [];

  for (var i = 0; i < selection.rangeCount; i++) {
    ranges.push(selection.getRangeAt(i));
  }

  switch (active.tagName.toUpperCase()) {// .toUpperCase handles XHTML
    case 'INPUT':
    case 'TEXTAREA':
      active.blur();
      break;

    default:
      active = null;
      break;
  }

  selection.removeAllRanges();
  return function () {
    selection.type === 'Caret' && selection.removeAllRanges();

    if (!selection.rangeCount) {
      ranges.forEach(function (range) {
        selection.addRange(range);
      });
    }

    active && active.focus();
  };
};

var _noop = require('lodash/noop');

var _noop2 = _interopRequireDefault(_noop);

function _interopRequireDefault(obj) { return obj && obj.__esModule ? obj : { 'default': obj }; }
