最近一直学习Angular.js,在学习过程中也练习了很多的Demo,这里先贴一下表格+分页。
先上图看看最终结果:
不得不说Angular.js代码风格很受人欢迎,几十行代码清晰简洁的实现了上面的功能。
首先表格的数据源来自于,Server.js 点击下载。通过get取数后分页显示。
1.表格是通过ng-repeat来展示的,代码如下:
<table class="table table-bordered"> <tr> <th>index</th> <th ng-repeat="(x,y) in items[0]">{{ x }}</th> </tr> <tr ng-repeat="x in items"> <td>{{ $index + 1 }}</td> <td ng-bind="x.Name"></td> <td ng-bind="x.City"></td> <td ng-bind="x.Country"></td> </tr></table>
$index是repeat的默认参数。表格的列头是通过数据源(json)的第一行循环取的key值。当然要是Bootstrap要指定table的Class是table table-bordered。
2.分页是也是用ng-repeat,不得不说ng-repeat是常用指令。分页代码如下:
<nav> <ul class="pagination"> <li> <a ng-click="Previous()"> <span>上一页</span> </a> </li> <li ng-repeat="page in pageList" ng-class="{active: isActivePage(page)}" > <a ng-click="selectPage(page)" >{{ page }}</a> </li> <li> <a ng-click="Next()"> <span>下一页</span> </a> </li> </ul></nav>
这里用了ng-click事件指令。还用到ng-class指令
ng-class="{active: isActivePage(page)}"
上面的代码是为了分页选中的样式。
这个表格加分页是假分页,从后端取一次数据,通过不同的分页显示json的筛选数据。
具体代码+注释:
