滚动到同一文档中两个不同列表中具有相同 id 值的元素

Question

In the following case there are two lists, one being nested within the other.

<q-list>
    <q-item
        v-for="item in data"
        :key="item.id_data"
        :id="item.id_data"
        >
        <q-item-section>
            <div>
                <span {{ item.name }} </span>

                <q-item
                    v-for="stuff in item"
                    :key="stuff.id_stuff"
                    :id="stuff.id_stuff">
                    <q-item-section>
                        <span"> {{ stuff.name }} </span>
                    </q-item-section>
                </q-item>

            </div>
        </q-item-section>
    </q-item>
</q-list>

Two click events can be triggered that generated a scroll to a element of the lists:

1- In the first case, the scroll must be done for the element to which the id corresponds to item.id_data

2- In the second case, the scroll must be done for the element to which the id corresponds to stuff.id_stuff

This means that the data id value can match the stuff id value (ie, item.id_data = 4 , stuff.id_stuff = 4 ).

This causes problems when using document.getElementById(id).

Example of the scrollTo function:

scrollTo (id) {
    const ele = document.getElementById(id)
    const target = getScrollTarget(ele)
    const offset = ele.offsetTop - ele.scrollHeight    
    const duration = 500
    setScrollPosition(target, offset, duration)
},

how to solve this?

Answer 1

You could bind a prefix to each ID to differentiate them:

<q-list>
    <q-item
        v-for="item in data"
        :key="item.id_data"
               👇
        :id="'data_' + item.id_data"
        >
        <q-item-section>
            <div>
                <span {{ item.name }} </span>

                <q-item
                    v-for="stuff in item"
                    :key="stuff.id_stuff"
                            👇
                    :id="'stuff_' + stuff.id_stuff">
                    <q-item-section>
                        <span"> {{ stuff.name }} </span>
                    </q-item-section>
                </q-item>

            </div>
        </q-item-section>
    </q-item>
</q-list>
