ionic侧边栏字母导航

$scope.show = function (c) {

var y = 0;

for (var i = 0; i < $scope.items.length; i++) {

var obj = $scope.items[i].name;

var pinyin = ConvertPinyin(obj);

console.log(c + ":" + pinyin.substr(0, 1).toUpperCase());

if (c == pinyin.substr(0, 1).toUpperCase()) {

break;

}

y += 51;

}

//如果查得到则跳转

if (i != $scope.items.length) {

$ionicScrollDelegate.scrollTo(0, y);

}

}

之所以选51px 由于item元素高度为51px
