我需要gridview,其中包含'n'行,每行将显示4列/项。我想只使用Html / Javascript / Vuejs模板。
我想要实现以下视图: 在上图中,我们有“查看全部”按钮,可以说我们有32个数据集,网格应该有8行,每行有4个项目/列。最初我需要只有两行(显示8项)和“查看全部”,当我点击按钮时,它应该展开并显示所有行和项目。使用'查看更少'文本。当我再次点击时,它应该折叠,并且应该只显示2行和8个项目。
<template>
<div>
<list>
<cell style="flex-direction:row; align-items:center ;" v-for="(rowdata,index) in griddata" :key="index" >
<div v-for="(rowitem, i) in rowdata" style="flex:1;flex-direction:column; backgroundColor:blue;margin:10px;height:100px; align-items:center;" :key="i">
<image class="item-icon" src="https://gw.alicdn.com/tfs/TB1788ygMMPMeJjy1XdXXasrXXa-1919-1520.jpg"></image>
<text style="color:white;justify-content:center;align-items:center;backgroundColor:red;flex:1; text-align:center;">{{rowitem}}</text>
</div>
</cell>
</list>
<text class="view-all-container" v-if="viewText" >{{viewText}}</text>
</div>
</template>
<script>
export default {
props: {
data: Object,
},
data() {
return {
isOpen: false,
viewText: 'View All',
borderRight: 'item-border-right',
appearFlag: [],
griddata:[]
};
},
created() {
for(var i =0;i<5;i++){
var rowdata = []
rowdata.push("1")
rowdata.push("2")
rowdata.push("3")
this.griddata.push(rowdata)
}
},
}
</script>
<style scoped lang="sass?outputStyle=expanded">
.container {
background-color: #fff;
flex-direction: column;
align-items: center;
margin-bottom: 20px;
}
.icon-row {
width: 750px;
flex-direction: row;
align-items: flex-start;
}
.icon {
width: 188px;
height: 168px;
padding-top: 30px;
flex-direction: column;
justify-content: center;
align-items: center;
border-bottom-style: solid;
border-bottom-color: #ebebeb;
border-bottom-width: 1px;
}
.item-border-right {
border-right-style: solid;
border-right-color: #ebebeb;
border-right-width: 1px;
}
.item-icon {
width: 54px;
height: 54px;
margin-bottom: 15px;
}
.item-text {
padding-left: 14px;
padding-right: 14px;
font-size: 22px;
color: #666;
text-align: center;
lines: 2;
height: 64px;
text-overflow: ellipsis;
}
.view-all-container {
width: 750px;
margin-top: 30px;
margin-bottom: 30px;
text-align: center;
font-size: 26px;
font-weight: 500;
color: #ef4e28;
}
</style>
注意:我已经用Google搜索并验证了堆栈,无法获得任何解决方案。 Plz帮我解决了这个问题..

有很多不同的方法可以做到这一点。一种(简单)方法是在created
挂钩中加载初始网格,如下所示:
this.initialGrid = createGrid(2, 4)
createGrid
定义为:
const createGrid = (rows, cols) => {
const grid = []
for (let i = 0; i < rows; i++) {
grid[i] = []
for (let j = 0; j < cols; j++) {
grid[i][j] = "some/image" // could store respective image paths in an array and push them into the grid
}
}
return grid
}
如果您初始化createGrid
,这将为您提供包含四列的2行。然后在data
挂钩中,您可以将具有所需尺寸的网格存储为“原始网格”。模板可以简单如下:
<div id="grid">
<div class="flex-container"
v-for="rows in showGrid">
<!-- just a placeholder, you'd likely want an img tag, etc -->
<div v-for="cols in rows">
{{ cols }}
</div>
</div>
<button
v-show="!toggleLoadButton"
@click="toggleLoadButton = true"
>
show more
</button>
<button
v-show="toggleLoadButton"
@click="toggleLoadButton = false"
>
show less
</button>
</div>
以下是一个示例:https://codepen.io/anon/pen/VxQeRV?editors=1010 此解决方案仅限于加载两行或所有行。
