我有一个div,其中我有一些争论。我需要从该div中搜索文本并突出显示该单词(使用css类)。接下来它搜索下一个单词出现和上一次出现。 我可以在jquery中作为小提琴中的例子 http://jsfiddle.net/3MVNj/5/ 你能告诉我如何在棱角分明的js中达到这个目的吗? plunker http://plnkr.co/edit/V805fEjJAUbAZIuafJcW?p=preview

有没有办法搜索过滤器?

您可以使用旧的搜索算法,例如:http://plnkr.co/edit/As9iyCVtMMNH7lyprJA9?p=preview

添加的是

<button ng-click="searchFirst(searchtext)">FirstText</button>

示例搜索,仅转发(prev实现而非AngularJS相关)(请参阅运行示例的链接):

尝试搜索&#34; sear&#34; ...仅对该字词进行了测试... =)

app.controller("contr",function($scope){

  var searcher = new Searcher();

  var div = angular.element(document.getElementById('content'));

  $scope.searchFirst=function(str){
    searcher.setOffset(0);
    searcher.setContent(div.text());
    div.html(searcher.search(str));
  }

  $scope.nextSearch=function(){
    div.html(searcher.search());
  }

   $scope.preSearch=function(){
     // you implement
  }
});
