一. 真分页表格基础
1. 需求：分页，排序，搜索都是需要发API到服务端。
2. JS实现代码：
getStorage是localStorage一个工具方法，可以自己写这个方法。
API参数如下：
{
limit: initItemCountPerPage,
index: options1.page,
sortKey: options1.sortKey ? encodeURIComponent(options1.sortKey) : ‘‘,
sortType: options1.sortType ? options1.sortType: ‘‘,
searchWord: ‘‘
}
angular.module(‘newApp‘)
.factory(‘ListTableSV‘, [‘$timeout‘, ‘ngTableParams‘, ‘getStorage‘, function ($timeout, ngTableParams, getStorage) {
var store = getStorage(‘localStorage‘);
/**
* 创建表格
* @param options1
* @param options2
* @returns {ngTableParams|*}
*/
function createListTable(options1, options2) {
var listTable = new ngTableParams(options1, {
counts: options2.counts,
getData: function ($defer, params) {
if (!listTable.isNotFisrtLoadData) {
listTable.apiParams = initApiParams(options1);
}
listTable.isNotFisrtLoadData = true;
options2.getData(listTable.apiParams).then(function (data) {
listTable.resetCheckboxes();
var resData = data.data.data;
var onDataResult = options2.onDataResult;
if (onDataResult) {
onDataResult(resData);
}
var items = resData.items;
var dataPreprocessFunc = options2.dataPreprocessFunc;
if (dataPreprocessFunc) {
dataPreprocessFunc(items);
}
var totalCount = resData.totalCount ? resData.totalCount : 0;
params.items = (items && totalCount) ? items : [];
listTable.calculatePages(totalCount);
params.total(totalCount);
$defer.resolve(params.items);
return;
}, function () {
params.items = [];
var totalCount = 0;
listTable.calculatePages(totalCount);
params.total(totalCount);
$defer.resolve(params.items);
return;
});
}
});
listTable.tableName = options1.tableName;
listTable.titles = options1.titles;
listTable.getItemId = options2.getItemId;
listTable.toFirstPageAndReload = function () {
if (listTable.page() == 1) {
listTable.reload();
} else {
listTable.toPage(1);
}
};
return listTable;
};
function initApiParams(options1) {
var STORAGE_PAGESIZE_KEY = getKeyForStoragePageSize(options1);
if (store.get(STORAGE_PAGESIZE_KEY)) {
var initItemCountPerPage = store.get(STORAGE_PAGESIZE_KEY)[‘value‘];
} else {
var initItemCountPerPage = options1.count;
}
return {
limit: initItemCountPerPage,
index: options1.page,
sortKey: options1.sortKey ? encodeURIComponent(options1.sortKey) : ‘‘,
sortType: options1.sortType ? options1.sortType: ‘‘,
searchWord: ‘‘
};
}
/**
* 初始化排序功能
* @param listTable
*/
function initSort(listTable, options1) {
listTable.sortClickIndex = 0;
listTable.sortClickDelayIndex = 0;
listTable.sortDelay = 750;
listTable.nextSortType = function () {
return listTable.sortParams.type == ‘asc‘ ? ‘desc‘ : ‘asc‘;
};
listTable.isColumnSorting = function (key) {
return listTable.sortParams.key == key;
};
listTable.isColumnSortingByASC = function (key) {
return listTable.isColumnSorting(key) && listTable.sortParams.type == ‘asc‘;

};
/**

*/
function initCheckboxes(listTable, withCheckboxes) {
if (withCheckboxes) {
listTable.toggleCheckAll = function () {
var checkedCount = listTable.checkedIds().length;

}

return listTable;
};
/**

initSort(listTable, options1);
initCheckboxes(listTable, options1.withCheckboxes);
initPagination(listTable, options1);
return listTable;
};
return {
init: init,
};
}]);
2. html分页代码
<div class="ng-cloak dahuo-pagination" ng-if="params.pages.length > 0">
<div class="col-lg-6">
<div class="dataTables_info" role="status" aria-live="polite" ng-if="params.pages.length > 0">
{{ params.count() * (params.page() - 1) + 1 }}~
{{ params.count() * (params.page() - 1) + params.data.length }}条，共{{
params.total() }}条记录
</div>
</div>
<div class="col-lg-6 pagination2" style="margin-bottom: 40px">
<div class="dataTables_paginate paging_simple_numbers">
<ul class="pagination ng-table-pagination">
<li><a href="" ng-click="params.prePage()">上一页</a></li>
<li ng-repeat="page in params.pages" ng-class="{‘active‘ : page == params.page()}">
<a href="" ng-click="params.toPage(page)">{{ page }}</a>
</li>
<li><a href="" ng-click="params.nextPage()">下一页</a></li>
</ul>
</div>
<div class="col-lg-3 pull-right">
<select class="select form-control" ng-model="params.editCount" ng-change="params.toCount(params.editCount)" style="padding: 6px; margin-top: 2px;min-width: 80px;margin-right: 10px" ng-options="size for size in params.settings().counts">
</select>
</div>
</div>
</div>
3. 说明：
基本实现了分页，搜索，排序（仅仅支持单个排序）等功能。搜索和排序会返回第一页。
二. 使用方法
服务端应该返回结果{data:{data: {items: [{name1: ...}, {...}]}}};
1. html中Table部分的代码
没有什么其他说的，这么写就行了。
<div class="table-responsive">
<table ng-table="productsTable" class="table trans-table table-hover text-left dahuo-table" template-pagination="layouts/pagination_v3.html" width="100%">
<thead>
<tr>
<th width="5%" class="dahuo-table-header-th text-center" header="‘ng-table/headers/checkbox.html‘">
<span class="list-checkbox">
<input type="checkbox" ng-model="productsTable.checkboxes.selectAll" ng-disabled="productsTable.items.length < 1" ng-click="productsTable.toggleCheckAll()"/>
<span></span>
</span>
</th>
<th width="15%" ng-repeat="title in productsTable.titles" ng-class="{‘sort‘: title.sortable}"
ng-click="productsTable.toSorting(title.key, productsTable.nextSortType())">
{{ title.name }}
<li class="fa pull-right" ng-if="title.sortable" ng-class="{‘fa-sort-asc‘: productsTable.isColumnSortingByASC(title.key), ‘fa-sort-desc‘: productsTable.isColumnSortingByDESC(title.key), ‘fa-unsorted‘: !productsTable.isColumnSorting(title.key)}" aria-hidden="true" ng-style="{‘color‘ : (!productsTable.isColumnSorting(title.key) ? ‘#c9c9c9‘ : ‘‘)}"></li>
</th>
</tr>
</thead>
<tbody>
<tr ng-repeat="item in $data">
<td width="5%" header="‘ng-table/headers/checkbox.html‘"
class="str-checkbox, dahuo-table-body-th text-center">
<span class="list-checkbox">
<input type="checkbox" ng-model="productsTable.checkboxes.items[item.id]" disabled/>
<span></span>
</span>
</td>
<td>{{item.name1}}</td>
<td>{{item.name2}}</a></td>
<td>{{item.name3}}</td>
<td>{{item.name4}}</td>
<td>{{item.name5}}</td>
</tr>
<tr style="height: 100px" ng-if="$data.length < 1">
<td colspan="6" class="text-center">暂时没有数据</td>
</tr>
</tbody>
</table>
</div>
2. Controller调用
DS是发送API的一个服务。这里可以改成自己要发的API，改的时候注意使用$q服务返回值。
$scope.productsTable = new ListTableSV.init(
{
tableName:‘fund.update.list.products‘,
titles:[
{key: ‘name1‘, name: "名字1", sortable: true},
{key: ‘name2‘, name: "名字2", sortable: true},
{key: ‘name3‘, name: "名字3", sortable: true},
{key: ‘name4‘, name: "名字4", sortable: true},
{key: ‘name5‘, name: "名字5", sortable: true},
],
withCheckboxes: true,
page: 1,
count: 25,
sortKey: ‘name1‘,
sortType: ‘desc‘
},
{
counts: [10, 25, 50, 100],
getData: function(apiParams) {
return DS.simplelist(apiParams);
},
getItemId: function(item) {
return item.id;
}
}
);
三. 搜索的调用方法
很好调用，就两行代码，先更改API，在reload。
$scope.productsTable.apiParams.searchWord = encodeURIComponent($scope.keyword); $scope.productsTable.toFirstPageAndReload();
