使用拖放REDIPS

Question

我正在使用一个名为REDIPS的库，它允许您创建一个可定制且简单的拖放效果.

我正在尝试创建一个函数，该函数导致正在移动的元素多次被克隆，并定位在主元素的左侧.

​

(function() {
  var redipsInit,
      getContent;

  redipsInit = function() {
    var num = 0,
        rd = REDIPS.drag;
    rd.init();
    rd.dropMode = 'single';
    rd.hover.colorTd = 'rgb(62, 255, 110)';
    rd.event.clicked = function() {
      if (rd.obj.id == 'drag-1' || rd.obj.id == 'drag-4') {
        for (var i = 0; i < 1; i++) {
          var mydiv = rd.obj;
          var div = document.createElement("div");
          insertAfter(div, mydiv);
          div.className = rd.obj.className;
          div.style.backgroundColor = rd.obj.style.backgroundColor;
        }
      } else if (rd.obj.id == 'drag-2' || rd.obj.id == 'drag-5' || rd.obj.id == 'drag-9') {
        for (var i = 0; i < 3; i++) {
          var mydiv = rd.obj;
          var div = document.createElement("div");
          insertAfter(div, mydiv);
          div.className = rd.obj.className;
          div.style.backgroundColor = rd.obj.style.backgroundColor;
        }
      }
    };
  }
  getContent = function(id) {
    var td = document.getElementById(id),
        content = '',
        cn, i;
    for (i = 0; i < td.childNodes.length; i++) {
      cn = td.childNodes[i];
      if (cn.nodeName === 'DIV' && cn.className.indexOf('drag') > -1) {
        content += cn.id + '_';
      }
    }
    content = content.substring(0, content.length - 1);
    return content;
  };

  teste = function() {
    var k = 1;
    var tabela = '';
    tabela = '<table>';
    for (var i = 1; i < 7; i++) {
      tabela += '<tr>';
      for (var j = 1; j < 10; j++) {
        tabela += '<td class="redips-drag containerDrop" id="td' + k + '"></td>';
        k++;
      }
      tabela += '</tr>';
    }
    tabela += '</table>';
    document.getElementById('areaPlotar').innerHTML = tabela;
  };

  insertAfter = function(newNode, referenceNode) {
    referenceNode.parentNode.insertBefore(newNode, referenceNode.nextSibling);
  };

  teste();
  redipsInit();

})();

单击该元素希望他被这样拉，例如，如果它被设置为占据三个区域：

​

​

当您将元素添加到plotável区域时，应该如下所示：

我在网站上提供的文件上读了一遍，但还是很难创造出这种逻辑.

原谅英语不好，但英语说得不流利.

Answer 1

我是REDIPS.drag的开发人员，请看下面的jsFiddle演示：

http://jsfiddle.net/dvxokzLw/1/

演示展示了如何克隆放置在目标单元旁边的DIV元素。JavaScript代码很简单，应该是继续开发的良好基础：

// define event handler after cloned element is dropped
// tc is target cell reference (where element is dropped)
rd.event.clonedDropped = function (tc) {
    var n1 = tc.nextElementSibling, // first cell next to dropped element
        n2,                         // second cell next to dropped element
        objNew;                     // cloned element
   // clone first element (if next cell exists)
   if (n1) {
      n2 = n1.nextElementSibling,      // try to set reference to second cell
      objNew = rd.cloneObject(rd.obj); // clone itself
      n1.appendChild(objNew);          // append to first cell
   }
   // clone second element (if second cell exists)
   if (n2) {
      objNew = rd.cloneObject(rd.obj); // clone itself
      n2.appendChild(objNew);          // append to second cell
   }
};
