[英]how to search and highlight in angular js?
我有一個div,其中有一些要解決的問題。我需要從該div中搜索文本並突出顯示單詞(使用css類)。 我可以在小提琴http://jsfiddle.net/3MVNj/5/中以jquery為例進行制作,您能否建議我將如何在angular js中實現呢? 塞子http://plnkr.co/edit/V805fEjJAUbAZIuafJcW?p=preview

<button ng-click="preSearch()">PreviousSearch</button>
<div id="contend">hello I need to search text from the contend
.On click of search it search the first word.
</div>
</div>
<script>
var app=angular.module('app',[]);
app.controller("contr",function($scope){
$scope.searchFirst=function(){
alert('search First text')
}
$scope.nextSearch=function(){
alert('nextSearch')
}
$scope.preSearch=function(){
alert('preSearch')
}
});

有什么辦法可以搜索過濾器?
您可以使用舊的搜索算法作為示例: http : //plnkr.co/edit/As9iyCVtMMNH7lyprJA9?p=preview
添加的是
<button ng-click="searchFirst(searchtext)">FirstText</button>
示例搜索,僅轉發(與AngularJS不相關的上一個實現)(請參見運行示例的鏈接):
嘗試搜索“ sear” ...僅對該單詞進行過測試... =)
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
}
});
