"Fake pagination and VueJS" - pagination

Question

I would like (for the moment) to implement what I call a fake pagination.
I have a table that is populated with a bunch of data. I get the whole data set with AJAX but the table is big.
My question is : How can I implement someting to display the first 10 items of my table then if I click on page 2 it is going to take the item from 11 to 21 and so on...
<!-- component template -->
<script type="text/x-template" id="grid-template">
<table>
<thead>
<tr>
<th v-for="key in columns"
#click="sortBy(key)"
:class="{ active: sortKey == key }">
{{ key | capitalize }}
<span class="arrow" :class="sortOrders[key] > 0 ? 'asc' : 'dsc'">
</span>
</th>
</tr>
</thead>
<tbody>
<tr v-for="entry in filteredData">
<td v-for="key in columns">
{{entry[key]}}
</td>
</tr>
</tbody>
</table>
</script>
<!-- demo root element -->
<div id="demo">
<form id="search">
Search <input name="query" v-model="searchQuery">
</form>
<demo-grid
:data="gridData"
:columns="gridColumns"
:filter-key="searchQuery">
</demo-grid>
</div>
// register the grid component
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
}
},
computed: {
filteredData: function () {
var sortKey = this.sortKey
var filterKey = this.filterKey && this.filterKey.toLowerCase()
var order = this.sortOrders[sortKey] || 1
var data = this.data
if (filterKey) {
data = data.filter(function (row) {
return Object.keys(row).some(function (key) {
return String(row[key]).toLowerCase().indexOf(filterKey) > -1
})
})
}
if (sortKey) {
data = data.slice().sort(function (a, b) {
a = a[sortKey]
b = b[sortKey]
return (a === b ? 0 : a > b ? 1 : -1) * order
})
}
return data
}
},
filters: {
capitalize: function (str) {
return str.charAt(0).toUpperCase() + str.slice(1)
}
},
methods: {
sortBy: function (key) {
this.sortKey = key
this.sortOrders[key] = this.sortOrders[key] * -1
}
}
})

var demo = new Vue({

]
}

Answer 1

I would probably create a numeric property called page to pass to the component (first page = 0, etc.), and then change the component template to
<tr v-for="entry in filteredData.slice(page*10, 10)">
There's certainly some refinement to do with error checking the bounds of the page variable, etc., but this should be a good start.
