AngularJS实现的自定义过滤器简单示例

angular.module('demo').filter('cut', function($sce) {
return function(value, wordwise, max, tail) {
if (!value) return '';
max = parseInt(max, 10);
if (!max) return value;
if (value.length <= max) return value;
if(value.length > max){
  value = value.substr(0, max);
}
if (wordwise) {
  var lastspace = value.lastIndexOf(' ');
  if (lastspace != -1) {
  value = value.substr(0, lastspace);
  }
}
return $sce.trustAsHtml(value + (tail || ' … <span>显示全文</span>'));
};
});

angular.module('demo').filter('stateFormat', ['state', function (state) {
  return function(input, type){
    if(type == 'stateColor'){
      switch (input){
        case '1': return 'green';break;
        case '0': return 'red';break;
      }
    } else if(type == 'stateText'){
      switch (input){
        case '1': return '特价';break;
        case '0': return '未特价';break;
      }
    } else if(type == 'marry'){
      switch (input){
        case '1': return '黄焖鸡米饭';break;
        case '2': return '水煮肉片';break;
        case '3': return '酸菜鱼';break;
      }
    } else(type == 'propertyColor'){
      switch (input){
        case '1': return 'blue';break;
        case '-1': return 'red';break;
        case '0': return ''; break;
      }
    }
