标签: javascript gettime

我正在创建一个应该自动停止<b>的程序。所以请告诉我如何,这是我想的一点点:

var time = date.getTime();
var seconds = 0;
if (time + seconds == date.getTime())
{
// Stop everything i do by myself :)
}

这样的事情:

<!-- 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
  },

    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: {

// bootstrap the demo

我们可以结合使用 setIntervalsetTimeout 来实现这一点。

function doStuff(){
    //do whatever you need to do
}

var is_running = true;

setTimeout(function(){
    is_running = false; //Stop the program
}, 1000 * 60 * 60); //Do this after 1 hour

while(is_running){
    doStuff(); //whatever your function does
}
