问题描述
我正在使用
选中所有用户"时,应选中所有复选框.
我创建了一个行布局并将这一行分成两个弹性框,所以我有两列的行结构.我使用'v-for'循环并为每一行显示当前索引和下一个索引的值.但是下一次循环迭代时会重复最后一个条目.我能到达的最近距离如下图:

我也尝试使用 table 而不是 layout 和 flex 但无法做到.在 codepen 中,我使用函数 'checkLength' 来获取下一个索引,因为使用预增量运算符递增 'index' 会产生错误(可能是由于数组超出范围).
我正在努力解决以下问题:
1) 我们如何在 Vuetify 中显示所需的输出?
2) 有没有像我们在 Javascript 中所做的那样以2"的增量迭代v-for"?例如:
for(var i=0;i
你应该把 v-layout
放在 v-for
<div class="mr-4 ml-4 whiteback userGroupHeight"><v-layout 换行><v-flex v-for="(category,index) in types" :key="types[index].text" xs6><v-checkbox light :label="category.text" v-model="category.selected"></v-复选框></v-flex></v-布局></div>
那么你就不需要使用checkLength
方法了.

I'm using theVuetifyJsfor VueJS and I'm trying to display checkbox in table format from an array of objects.Desired Output shown below :
When 'All Users' is checked all the checkboxes should be checked.
I created a row layout and divided this row into two flex boxes so I have the structure of row with two columns. I loop using 'v-for' and for every row display the value of the current index and the next index. But the last entry is repeated the next time the loop is iterated. The closest I could reach is as shown below:

I also tried to use table instead of layout and flex but could not make it. In the codepen I use the function 'checkLength' to get the next index because incrementing the 'index' with pre-increment operator gives error(probably due to array goes out of bounds).
I am struggling with the below queries :
1) How can we display the desired output in Vuetify ?
2) Is there anyway to iterate 'v-for' with increment of "2" like we can do in Javascript ?ex:
for(var i=0;i<array.length();i += 2)
You should put v-layout
outside of v-for
<div class="mr-4 ml-4 whiteback userGroupHeight">
<v-layout row wrap>
<v-flex v-for="(category,index) in types" :key="types[index].text" xs6>
<v-checkbox light :label="category.text" v-model="category.selected">
</v-checkbox>
</v-flex>
</v-layout>
</div>
then you don't need to use checkLength
method.
