Question

我需要像data-id，data-action

<div class="dd" id="nestable3">
        <ol class="dd-list">
            <li class="dd-item dd3-item" data-id="13">
                <div class="dd-handle dd3-handle">Drag</div><div class="dd3-content">Item 13</div>
            </li>
            <li class="dd-item dd3-item" data-id="14">
                <div class="dd-handle dd3-handle">Drag</div><div class="dd3-content">Item 14</div>
            </li>
            <li class="dd-item dd3-item" data-id="15">
                <div class="dd-handle dd3-handle">Drag</div><div class="dd3-content">Item 15</div>
                <ol class="dd-list">
                    <li class="dd-item dd3-item" data-id="16">
                        <div class="dd-handle dd3-handle">Drag</div><div class="dd3-content">Item 16</div>
                    </li>
                    <li class="dd-item dd3-item" data-id="17">
                        <div class="dd-handle dd3-handle">Drag</div><div class="dd3-content">Item 17</div>
                    </li>
                    <li class="dd-item dd3-item" data-id="18">
                        <div class="dd-handle dd3-handle">Drag</div><div class="dd3-content">Item 18</div>
                    </li>
                </ol>
            </li>
        </ol>
    </div>

我需要创建属性data-id =“13”。 如何使用knockout js attr绑定创建它...

使用attr绑定data-bind="attr: {'data-id': id}"
