vue2 v-model/v-text 中使用过滤器的方法示例

<!-- 在双花括号中 -->
{{ message | capitalize }}

<!-- 在 v-bind 中 -->
<div v-bind:id="rawId | formatId"></div>

filters: {
  dateFormat： (dataStr) => {
   var time = new Date(dataStr);
  
   function timeAdd0(str) {
    if (str < 10) {
     str = '0' + str;
    }
    return str
   }
   var y = time.getFullYear();
   var m = time.getMonth() + 1;
   var d = time.getDate();
   var h = time.getHours();
   var mm = time.getMinutes();
   var s = time.getSeconds();
   return y + '-' + timeAdd0(m) + '-' + timeAdd0(d) + ' ' + timeAdd0(h) + ':' + timeAdd0(mm) + ':' + timeAdd0(s);
  }
}

Vue.filter('dateFormat', (dataStr) => {
 var time = new Date(dataStr);

 function timeAdd0(str) {
  if (str < 10) {
   str = '0' + str;
  }
  return str
 }
 var y = time.getFullYear();
 var m = time.getMonth() + 1;
 var d = time.getDate();
 var h = time.getHours();
 var mm = time.getMinutes();
 var s = time.getSeconds();
 return y + '-' + timeAdd0(m) + '-' + timeAdd0(d) + ' ' + timeAdd0(h) + ':' + timeAdd0(mm) + ':' + timeAdd0(s);
})
