10

我不明白为什么 IE10 认为索引 1 和 6 的选项无效？我期望索引 0 处的唯一选项应该失败并阻止表单提交。

<select required="required">
    <option value="">Select</option>
    <optgroup label="First">
        <option value="A">1</option>
        <option value="B">2</option>
        <option value="C">3</option>
        <option value="D">4</option>
    </optgroup>
    <optgroup label="Second">
        <option value="1">A</option>
        <option value="2">B</option>
        <option value="3">C</option>
        <option value="4">D</option>
    </optgroup>
</select>

我们遇到了同样的问题。

在一天的大部分时间里都在与此作斗争后，我们的一位开发人员（克里斯·麦克唐纳 - 必须在应得的情况下给予信用）通过value="0"在选项组标签中添加 a 来找到解决此问题的方法。

这是有问题的原始代码：http: //jsfiddle.net/PHEej/1/

<form id="addToCart" class="trackForm" method="post" action="/socks/jmx">

<div id="purchase" price=" $13.99 - $14.99">
<ol>
    <li id="purchase_promotion" class="price" price=" $13.99 - $14.99">
        <label class="retailPrice required" for="purchase_promotion"></label>
        <span itemprop="offers" itemscope itemtype="http://schema.org/Offer">
            <span itemprop="price"> $13.99 - $14.99</span>
        </span>
    </li>
    <li id="purchase_sizes" class="size">
        <label for="purchase_sizes" class="required">Shoe Size</label>
        <select id="purchase_sizes" name="purchase[sizes]" required="required" class="size">
            <option value="">Choose a shoe size</option>
            <optgroup label="men - us">
                <option value="1">5.5 to 8.5 - $13.99</option>
                <option value="2">9 to 12.5 - $13.99</option>
                <option value="3">13 to 15 - $14.99</option>
            </optgroup>
            <optgroup label="women - us">
                <option value="4">6.5 to 10 - $13.99</option>
                <option value="5">10.5 to 13 - $13.99</option>
            </optgroup>
        </select>
    </li>
    <li id="purchase_color"><label for="purchase_color" class="required">Colors</label><select
                id="purchase_color" name="purchase[color]" required="required">
            <option value="">Choose your color</option>
            <option value="93">White/platinum</option>
            <option value="92">White/navy</option>
        </select></li>
    <li id="purchase_quantity"><label for="purchase_quantity" class="required">Quantity</label><select
                id="purchase_quantity" name="purchase[quantity]" required="required">
            <option value="">Choose a quantity</option>
            <option value="1">1</option>
            <option value="2">2</option>
            <option value="3">3</option>
            <option value="4">4</option>
            <option value="5">5</option>
            <option value="6">6</option>
            <option value="7">7</option>
            <option value="8">8</option>
            <option value="9">9</option>
            <option value="10">10</option>
            <option value="11">11</option>
            <option value="12">12</option>
            <option value="13">13</option>
            <option value="14">14</option>
            <option value="15">15</option>
        </select></li>
    <input type="hidden" id="purchase_slug" name="purchase[slug]" value="jmx"/>
    <input type="hidden" id="purchase__token" name="purchase[_token]"  value="26dcd00e64754376fadefb38a534df85996ce4d3"/>
</ol>
</div>
<button id="submitButton" type="submit" class="cartButton buttonBlock trackForm"
        data-ga_params="Add to Cart|Add to Cart Submit|">
    <span class="icon-cart-after">Add to cart</span>
</button>
</form>

在此示例中，如果您选择鞋码中的第一项或最后一项，则在提交表单时将无法识别该选择。

这是允许我们跳过它的“固定”代码：http: //jsfiddle.net/PHEej/3/

<form id="addToCart" class="trackForm" method="post" action="/socks/jmx">

<div id="purchase" price=" $13.99 - $14.99">

        <label class="retailPrice required" for="purchase_promotion"></label>
        <span itemprop="offers" itemscope itemtype="http://schema.org/Offer">
            <span itemprop="price"> $13.99 - $14.99</span>
        </span>
    </li>
    <li id="purchase_sizes" class="size">
        <label for="purchase_sizes" class="required">Shoe Size</label>
        <select id="purchase_sizes" name="purchase[sizes]" required="required" class="size">
            <option value="">Choose a shoe size</option>
            <optgroup value="0" label="men - us">
                <option value="1">5.5 to 8.5 - $13.99</option>
                <option value="2">9 to 12.5 - $13.99</option>
                <option value="3">13 to 15 - $14.99</option>
            </optgroup>
            <optgroup  value="0" label="women - us">
                <option value="4">6.5 to 10 - $13.99</option>
                <option value="5">10.5 to 13 - $13.99</option>
            </optgroup>
        </select>
    </li>
    <li id="purchase_color"><label for="purchase_color" class="required">Colors</label><select
                id="purchase_color" name="purchase[color]" required="required">

            <option value="4">4</option>
            <option value="5">5</option>
            <option value="6">6</option>

            <option value="12">12</option>
            <option value="13">13</option>
            <option value="14">14</option>
            <option value="15">15</option>
        </select></li>
    <input type="hidden" id="purchase_slug" name="purchase[slug]" value="jmx"/>
    <input type="hidden" id="purchase__token" name="purchase[_token]"  value="26dcd00e64754376fadefb38a534df85996ce4d3"/>
</ol>
</div>
<button id="submitButton" type="submit" class="cartButton buttonBlock trackForm"
        data-ga_params="Add to Cart|Add to Cart Submit|">
    <span class="icon-cart-after">Add to cart</span>
</button>
</form>

这似乎是一个可行的解决方案，因为无论如何选项组都是不可选择的。

这个问题（幸运的是？）比你想象的更容易预测。初步测试表明，当所选选项的索引与兄弟元素中optgroup其父级的索引匹配时，会发现表单无效。optgroup

本质上，组 0 中的项目 0 是无效的。第 1 组中的第 1 项也无效。而且，幸运的是，第 4 组中的第 4 项也是无效的（见模式？）。这肯定看起来像是某种错误。当select具有multiple布尔属性时，情况并非如此。

你可以在这里看到我对你的表格的修改：http: //jsfiddle.net/jonathansampson/c86eY/
