alpine.js表编辑就地功能

Question

我正在尝试使用Alpine.js使表列可以内联编辑。这个想法是有一个“编辑到位”的功能，所以当一个行被双击允许内容是可编辑的。我遇到的问题是，当单击一个单元格时，它会激活所有行。

理想的行为只是点击的行应该是可编辑的，所有其他的都应该保持不可编辑。

我在这里预览了这个问题，https://codepen.io/ezeagwulae/pen/ZEKeYGQ

<div x-data="data()" class="p-4">
    <div class="uppercase font-bold">shopping items</div>
    <template x-for="item in items">
        <div>
            <a @click.prevent @dblclick="toggleEditingState" x-show="!isEditing" x-text="item.item" class="select-none cursor-pointer underline font-lg text-blue-500"></a>
            <input type="text" x-model="text" x-show="isEditing" @click.away="toggleEditingState" @keydown.enter="disableEditing" @keydown.window.escape="disableEditing" class="bg-white focus:outline-none focus:shadow-outline border border-gray-300 rounded-lg py-2 px-4 appearance-none leading-normal w-128" x-ref="input">
        </div>
    </template>
</div>

Answer 1

在JS文件中，确保使用e.target获得双击输入字段。

在HTML模型中，应该将模型设置为item.item。下面是一个有用的例子。

HTML

<div x-data="data()" class="p-4">
    <div class="uppercase font-bold">shopping items</div>
    <template x-for="item in items">
        <div>
            <a @click.prevent @dblclick="toggleEditingState" x-show="!isEditing" x-text="item.item" class="select-none cursor-pointer underline font-lg text-blue-500"></a>
            <input type="text" x-model="item.item" x-show="isEditing" @click.away="toggleEditingState" @keydown.enter="disableEditing" @keydown.window.escape="disableEditing" class="bg-white focus:outline-none focus:shadow-outline border border-gray-300 rounded-lg py-2 px-4 appearance-none leading-normal w-128" x-ref="input">
        </div>
    </template>
</div>

JS

function data() {
    return {
        text: "Double click to edit",
        isEditing: false,
        toggleEditingState(e) {
            const el = e.target
            this.isEditing = !this.isEditing;

            el.focus()
        },
        disableEditing() {
            this.isEditing = false;
        },
        items: [
            { id: 1, item: "apple" },
            { id: 2, item: "eggs" },
            { id: 3, item: "milk" }
        ]
    };
}

有什么建议只使单击的行可编辑，而不是所有行？例如，如果“鸡蛋”应显示该行的输入字段，其他行应保持原样。

例如：
