In did that for AngularJS v1.2+
HTML:
<span ng-bind-html="highlight(textToSearchThrough, searchText)"></span>
JS:
$scope.highlight = function(text, search) {
if (!search) {
return $sce.trustAsHtml(text);
}
return $sce.trustAsHtml(text.replace(new RegExp(search, 'gi'), '<span class="highlightedText">$&</span>'));
};
CSS:
.highlightedText {
background: yellow;
}
angular ui-utils supports only one term. I'm using the following filter rather than a scope function:
app.filter('highlight', function($sce) {
return function(str, termsToHighlight) {
// Sort terms by length
termsToHighlight.sort(function(a, b) {
return b.length - a.length;
});
// Regex to simultaneously replace terms
var regex = new RegExp('(' + termsToHighlight.join('|') + ')', 'g');
return $sce.trustAsHtml(str.replace(regex, '<span class="match">$&</span>'));
};
});
And the HTML:
<span ng-bind-html="theText | highlight:theTerms"></span>
Try Angular UI
Filters -> Highlite (filter). There is also Keypress directive.
