javascript - How to make a list with datemarks on Vue.js? -


just have such view:

<div class="items">     <div class="datemark" data-date="1">today</div>     <div class="item" data-date="1">item 1</div>     <div class="item" data-date="1">item 2</div>     <div class="item" data-date="1">item 3</div>      <div class="datemark" data-date="2">tommorow</div>     <div class="item" data-date="2">item 1</div>     <div class="item" data-date="2">item 2</div>     <div class="item" data-date="2">item 3</div> </div>

with such data:

data = [     1: {         human: 'today',         date: 1,         items: [             item1: {                 name: 'test',                 date: 1 // possible here             },             item2: {...},         ]     },     2: {         human: 'tommorow',         date: 2,         items: [             item1: {...},             item2: {...},         ]     } ]

or can be:

data = [     item1: {         name: 'test',         date: 1 // possible here     },     item2: {         name: 'other',         date: 2 // possible here     },     ... ]

how make works , can sorted desc/asc datemarks , 'inside' datemarks range if have different hours , minutes also?

tried v-for simple lists, how datemarks?

thanks!

you don't have this, use computed property instead, , can see used slice, it's because want copy array instead of sorting elements in place:

const app = new vue({    el: '#app',    data: {      order: 'asc',      list: [          {              name: 'item1',              date: 1 // possible here          },          {              name: 'item2',              date: 2 // possible here          },          {              name: 'item3',              date: 3 // possible here          },          {              name: 'test',              date: 4 // possible here          },          {              name: 'other',              date: 5 // possible here          }      ]    },    computed: {        sortedlist() {            return this.list.slice(0)              .sort((a, b) => {                  if (this.order === 'asc') {                      return b.date - a.date;                  }                  return a.date - b.date;              })        }    },    methods: {        togglesort(type){            this.order = type;        }    }  });
<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.4.2/vue.js"></script>  <div id="app">    <div>      <button v-on:click="togglesort('asc')">asc</button>      <button v-on:click="togglesort('dsc')">dsc</button>    </div>    <div>      <div class="datemark" v-for="item in sortedlist">        <div class="item">{{item.name}}</div>      </div>    </div>  </div>

and reference, if you're doing comparison on real dates, use instead"

array.sort(function(a,b){   // turn strings dates, , subtract them   // value either negative, positive, or zero.   return new date(b.date) - new date(a.date); });

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m...
