我是该{{NUMPAGES}}值将由指令来计算分页指令的IM pression下。这是不是为我返回任何东西。

I was under the impression with the pagination directive that the {{numPages}} value would be calculated by the directive. It isn't returning anything for me.

有什么我缺少得到这个工作是否正常？我不希望有来计算的话，如果该指令应该做这对我来说。否则，寻呼是伟大的工作。

Is there anything I am missing to get this working properly? I don't want to have to calculate it, if the directive is supposed to be doing this for me. Otherwise paging is working great.

我有一个startFrom过滤器。

I have a startFrom filter.

.filter('startFrom', function () {
            return function (input, start) {

                if (input === undefined || input === null || input.length === 0
                 || start === undefined || start === null || start.length === 0 || start === NaN) return [];
                start = +start; //parse to int

                try {
                    var result = input.slice(start);
                    return result;

                } catch (e) {

                //    alert(input);
                }        
            };
        })

推荐答案

看起来你只是缺少 NUM-页=NUMPAGES在＆LT;＆分页GT; 标记。从本质上讲，你必须提供一个变量分页中返回的页数。这是通过完成NUM-页

Looks like you're just missing num-pages="numPages" on your <pagination> tag. Essentially you have to provide a variable to pagination in which to return the number of pages. This is done via num-pages

<pagination 
            num-pages="numPages" <!-- Add this here -->
            total-items="totalItems" 
            ng-model="currentPage" 
            max-size="maxSize" 
            items-per-page="itemsPerPage" 
            class="pagination-sm" 
            boundary-links="true" rotate="false">
</pagination>
