工作Mootools拖放和下降后排序。排序后需要ID替换以跟踪输入顺序

Question

描述： 拖放表单元素以构建稍后将显示的表单。

需要：   - 输入和textarea表单字段在排序后需要按顺序排列。我需要参考问题和说明的答案。现在，如果它们已经排序，我将不知道在以后查看记录时显示它们的顺序。可能有更好的方法，但我现在卡住了。

• 排序问题：直到拖放事件发生后，可排序区域才起作用。有些默认字段需要立即排序。

Answer 1

仅在第一次放置事件后添加sortables。要让.item_dz从初始化中排序，您可以在domeready函数打开后直接添加此行：http://jsfiddle.net/ke7nq/

 var sortableItem_dz = new Sortables().addItems($$('.item_dz'));

我建议您稍微更改.item_dz的HTML，以便包含问题和是/否元素。类似于下面的例子，因此每个块都在item_dz：

中

<div class="item_dz">
    <textarea class="" cols="43" rows="6" style="border: medium none; width: 240px; margin-left: 15px;" name="vf300-Q3" form="GeneralVerdict">[or] [Was &lt;? echo $all_pla;?&gt; excused from having to do all, or substantially all, of the significant things that the contract required &lt;? echo "[him/her/it]";?&gt; to do?</textarea>   
    <span class="delete"><button>Delete Line</button></span>
        <input type="radio" value="Yes" name="yes-a2b" style="width: 20px ! important; margin-left: 30px; margin-bottom: 4px;" />Yes
        <input type="radio" value="No" name="no-a2b" style="width: 20px ! important; margin-left: 30px; margin-bottom: 4px;">No<span class="delete" style="opacity: 0.7;" />
        <button>Delete Line</button>
    </span>
</div>

要在完成删除/排序后获取所有元素，您可以执行

var questions = document.getElements('.item_dz');
// or to get just the ID's: 
// var questions = document.getElements('.item_dz').map(function(el){ return el.get('id'); });

或使用.serialize()方法：http://mootools.net/docs/more/Drag/Sortables#Sortables:serialize
