我正在使用Vue.js(目前是v.1.x,很快就会更新),我想要一个包含一些数据的表行表。我使用Vue.js组件用.Color
过滤表行,但我希望在完成任何搜索/过滤之前隐藏表行。
有人可以帮帮我吗?我应该在某处放置某种事件监听器吗?哪个地方最好放?
这是一个JSFiddle:https://jsfiddle.net/m7sgaron/863/
filterBy

Vue.component('demo-grid', {
template: '#grid-template',
props: {
data: Array,
columns: Array,
filterKey: String
},
data: function () {
var sortOrders = {}
this.columns.forEach(function (key) {
sortOrders[key] = 1
})
return {
sortKey: '',
sortOrders: sortOrders
}
},
methods: {
sortBy: function (key) {
this.sortKey = key
this.sortOrders[key] = this.sortOrders[key] * -1
}
}
})
// bootstrap the demo
var demo = new Vue({
el: '#demo',
data: {
searchQuery: '',
gridColumns: ['name', 'power'],
gridData: [
{ name: 'Chuck Norris', power: Infinity },
{ name: 'Bruce Lee', power: 9000 },
{ name: 'Jackie Chan', power: 7000 },
{ name: 'Jet Li', power: 8000 }
]
}
})

body {
font-family: Helvetica Neue, Arial, sans-serif;
font-size: 14px;
color: #444;

table {
border: 2px solid #42b983;
border-radius: 3px;

}
td {
background-color: #f9f9f9;
}
th, td {
min-width: 120px;
padding: 10px 20px;
}
th.active {

}
th.active .arrow {
opacity: 1;
}
.arrow {
display: inline-block;
vertical-align: middle;
width: 0;
height: 0;
margin-left: 5px;
opacity: 0.66;
}
.arrow.asc {
border-left: 4px solid transparent;
border-right: 4px solid transparent;
border-bottom: 4px solid #fff;
}
.arrow.dsc {
border-left: 4px solid transparent;
border-right: 4px solid transparent;
border-top: 4px solid #fff;
}
#search {
margin-bottom: 10px;
}

最简单的方法是在v-show
上使用条件指令,例如v-if
或tr
。表达式会检查searchQuery
是否有一定长度。
<script type="text/x-template" id="grid-template">
<table>
<tbody>
<tr v-show="filterKey.length" v-for="
entry in data
| filterBy filterKey
| orderBy sortKey sortOrders[sortKey]">
<td v-for="key in columns">
{{entry[key]}}
</td>
</tr>
</tbody>
</table>
</script>
