角度搜索过滤结果

Question

当在输入中输入第一个字母时，结果显示包含该字母的所有字符串，而不是以字母开头的结果。是否有其他类型的内置过滤器或属性？

<input ng-model="search.RegionName">
<div class="item" ng-repeat="region in DividedRegionList | filter:search:strict" >

试试这个：

var app = angular.module('filterSample', []);
app.controller('filterCtrl', function ($scope) {

  $scope.data = {
    messages: ['first', 'second', '3rd', 'fourth', 'fifth']
  }

  $scope.startsWith = function (actual, expected) {
    var lowerStr = (actual + "").toLowerCase();
    return lowerStr.indexOf(expected.toLowerCase()) === 0;
  }
});

模板：

    <ul border="1px" ng-repeat="msg in data.messages | filter:search:startsWith">
      <li>{{msg}}</li>
    </ul>
