angualrJs对数据库数据处理的增删改查

angularJs框架主要运用于管理系统，对数据的增删改查，下面就详细的写写angualrJs在这4个方面的运用

通常状况下，咱们获得以下的一个简单的已经转换为页面的设计图

有4个按钮，它们的状态各不相同。其中添加和删除的初始状态是abled,修改和删除是disabled

html代码

1.按钮

<div class="small-box">
    <button class="btn btn-primary" ng-click="addOrEditLog('add')">
        添加
    </button>
    <button class="btn btn-primary" ng-disabled="UI.disableEdit()" ng-click="addOrEditLog('edit')">
        修改
    </button>
    <button class="btn btn-primary"  ng-disabled="UI.disableDelete()" ng-click="deleteList()">
        删除
    </button>
    <button class="btn btn-primary" ng-click="searchUpdateLog()">
        刷新
    </button>
</div>复制代码

2.表格

<div class="row">
        <div class="data-table">
            <table class="table table-bordered table-hover text-center">
                <thead>

                        <th width="5%">序号</th>
