ng-table 通过 select 下拉菜单过滤

Question

我正在尝试创建一个 Ng-table 以及一个 select 下拉菜单来过滤结果。这是我到目前为止得到的。

1) 如何摆脱因过滤器菜单而创建的分页？我只需要一个分页。我知道我可以通过 CSS .ng-table-pager { 显示：none； }.但是，这两个分页都会消失。

2) 默认过滤器菜单为空白，显示所有数据。这很棒。如何将空白字段更改为 "ALL" 文本字段？

3) 除了直接过滤，我可以在调用过滤功能之前添加一个提交按钮吗？

(function() {
    "use strict";

    angular.module("uCloud", ["ngTable"])
        .controller("myController", myController);

    myController.$inject = ["NgTableParams"];

    function myController(NgTableParams) {

        this.nameFilter = [
            {id:"teste1", title:"-> teste1"},
            {id:"teste2", title:"-> teste 2"},
            {id:"teste3", title:"-> teste 3"},
            {id:"teste4", title:"-> teste 4"},
            {id:"teste5", title:"-> teste 5"},
        ];



        this.objectTest = [

            {name: "teste1", description: "testando1"},
            {name: "teste2", description: "testando2"},
            {name: "teste3", description: "testando3"},
            {name: "teste4", description: "testando4"}
        ];

        this.tableParams = new NgTableParams({}, {
            dataset: this.objectTest
        });
    }
})();

Answer 1

首先要注意的是：警告，您正在加载 Angular 两次。删除指向 Angular.

的 <script> 标签之一

1) How do i get rid of the pagination created as a result of the filter menu? I only need one pagination.

您看到两个分页控件，因为您创建了两个 ng-table。您需要摆脱过滤器的 table 并为此使用普通的 select HTML 元素。

  <select ng-model="demo.tableParams.filter()['name']">
    <option value="">All</option>
    <option value="teste1">->teste1</option>
    <option value="teste2">->teste2</option>
    <option value="teste3">->teste3</option>
    <option value="teste4">->teste4</option>
    <option value="teste5">->teste5</option>
  </select>

2) The default filter menu is blank which shows ALL data. This is great. How do i change the blank field to "ALL" text field?

如上所示，只需添加一个option和value=""即可。这将使数据集中的所有项目都匹配。

3) Instead of straight away filtering, can i add a submit button before invoking the filter function?

查看 NgTable samples - change filter values programmatically。

工作演示 here。

    angular.module("uCloud", ["ngTable"])
  .controller("myController", myController);

myController.$inject = ["NgTableParams"];

function myController(NgTableParams) {

  this.tableParams = new NgTableParams({}, {
    dataset: [{
      name: "teste1",
      description: "testando1"
    }, {
      name: "teste2",
      description: "testando2"
    }, {
      name: "teste3",
      description: "testando3"
    }, {
      name: "teste4",
      description: "testando4"
    }],
  });
}
