说下我经常写菜单的方式:
菜单项是否高亮显示取决于controller中的highlight方法。
如果以Directive的方式会更简洁。
Directive大致是:
Highlighter = function($location){
var link = function(scope,element){
function setActive(){
var path = $location.path();
var className = scope.highlightClassName || 'active';
if(path){
angular.forEac(element.find('li'),function(li){
//
var anchor = li.querySelector('a');
//#/customers
var href=(anchor && anchor.href) ? anchor.href : anchor.getAttribute('data-href').replace('#','');
//customers
var trimmedHref = href.substr(href.indexOf('#/')+1,href.length);
var basePath = path.substr(0,trimmedHref.length);
if(trimmedHref === basePath){
angular.element(li).addClass(className);
} else {
angular.element(li).removeClass(className);
}
});
}
}
setActive();
scope.$on('$locationChangeSuccess',setActive);
};
return {
restrict: 'A',scope: {
highlightClassName: '@'
},link: link
}
};
menuHighlighter.$inject = injectParams;
angular.module('my.directives')
.directive('menuHighlighter',menuHighlighter);
}());
