将Angular滤镜与分页一起使用 [英] Using Angular filter with pagination

问题描述

我正在对ng-repeat中的一系列项目使用过滤器，如下所示:

I am using a filter on an array of items in a ng-repeat like this:

<input type="text" ng-model="filterText">

<li ng-repeat="item in displayItems | filter : {item_name: filterText}>

这可以正常工作并且可以完美过滤项目.出现问题是因为我将displayItems与uib-pagination元素一起使用.分页使用totalItems而不是displayItems.

This works fine and filters the items perfectly.The problem arises because I am using displayItems with a uib-pagination element. The pagination uses totalItems instead of displayItems.

<uib-pagination class="pagination-sm pagination"
    total-items="totalItems.length" ng-model="page" ng-change="changeItems()">
</uib-pagination>

很明显，我需要以某种方式将过滤器应用于总项目，然后创建displayItems，并将滤除的项目放在uib分页中.

Obviously I need to somehow apply the filter on the total-items, then create the displayItems, and put the filteredItems in the uib-pagination.

即.当人员键入时，在控制器中将过滤器应用于totalItems，然后创建分页所需的filteredItems.然后，我也从filteredItems创建displayItems.如何将其放入控制器而不是ng-repeat的HTML中?

Ie. When the person types, in the controller the filter is applied to the totalItems, and I create the filteredItems needed for the pagination. I also then create the displayItems from the filteredItems. How do I go about putting this into the controller and not in the HTML for the ng-repeat?

我不确定该怎么做.有什么想法吗?所有帮助都非常感谢....

I'm not sure how to do this. Any thoughts? All help much appreciated....

推荐答案

尝试

HTML

<li ng-repeat="item in filterData = (totalItems | filter : {itemName: filterText}) | limitTo:3:3*(page-1)">

和

<uib-pagination class="pagination-sm pagination" total-items="filterData.length" ng-model="page"
        ng-change="pageChanged()" previous-text="&lsaquo;" next-text="&rsaquo;" items-per-page=3></uib-pagination>

JavaScript

JavaScript,

$scope.pageChanged = function() {
  //var startPos = ($scope.page - 1) * 3;
  //$scope.displayItems = $scope.totalItems.slice(startPos, startPos + 3);
};
