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;      }    }
