  • 工作所得所思之一

    (1)angularJs的数据添加删除:

    每次添加后——>重新查询接口——>获取最新的数据——>ng-reapeat展示最新数据——>点击删除时——> 使用$scope.arrs.splice($index,1)删除本条

    要实现视图自动更新,可以在控制器代码里这样写(这个方法并没有尝试过

    $scope.delete = function(record) {
        $scope.records.splice($scope.records.indexOf(record), 1);
    };

    参考:http://blog.csdn.net/xin_x1n/article/details/53070144

    2、在使用angularjs实现加载效果时,先写一个加载动画,在请求发出但是未有请求结果这段时间,让他显示即可。

    分享一个个人觉得不错的pc端的加载效果(没有用图片的哦)

    html文件

    <div class="loadingBG">
        <div class="loading">
            <div class="spinner-container container1">
                <div class="circle1"></div>
                <div class="circle2"></div>
                <div class="circle3"></div>
                <div class="circle4"></div>
            </div>
            <div class="spinner-container container2">
                <div class="circle1"></div>
                <div class="circle2"></div>
                <div class="circle3"></div>
                <div class="circle4"></div>
            </div>
            <div class="spinner-container container3">
                <div class="circle1"></div>
                <div class="circle2"></div>
                <div class="circle3"></div>
                <div class="circle4"></div>
            </div>
        </div>
    </div>

    css文件

    <style>
        .loadingBG{width: 75px; height: 75px; border-radius: 10px; background-color: rgba(0,0,0,0.55); text-align: center; position: fixed; top:350px; left:48.5%; z-index:1054;}
        /*圆圈旋转*/
        .loading{width: 33px; height: 33px; left: 20px; top: 20px; position: absolute; clear: both;}
        .container1 > div, .container2 > div, .container3 > div{width: 6px; height: 6px; background-color: #fff; border-radius: 100%; position: absolute; -webkit-animation: bouncedelay 1.2s infinite ease-in-out; animation: bouncedelay 1.2s infinite ease-in-out; -webkit-animation-fill-mode: both; animation-fill-mode: both;}
        .loading .spinner-container{position: absolute; width: 100%; height: 100%;}
        .container2{-webkit-transform: rotateZ(45deg); transform: rotateZ(45deg);}
        .container3{-webkit-transform: rotateZ(90deg); transform: rotateZ(90deg);}
        .circle1{top: 0; left: 0;}
        .circle2{top: 0; right: 0;}
        .circle3{right: 0; bottom: 0;}
        .circle4{left: 0; bottom: 0;}
        .container2 .circle1{-webkit-animation-delay: -1.1s; animation-delay: -1.1s;}
        .container3 .circle1{-webkit-animation-delay: -1.0s; animation-delay: -1.0s;}
        .container1 .circle2{-webkit-animation-delay: -0.9s; animation-delay: -0.9s;}
        .container2 .circle2{-webkit-animation-delay: -0.8s; animation-delay: -0.8s;}
        .container3 .circle2{-webkit-animation-delay: -0.7s; animation-delay: -0.7s;}
        .container1 .circle3{-webkit-animation-delay: -0.6s; animation-delay: -0.6s;}
        .container2 .circle3{-webkit-animation-delay: -0.5s; animation-delay: -0.5s;}
        .container3 .circle3{-webkit-animation-delay: -0.4s; animation-delay: -0.4s;}
        .container1 .circle4{-webkit-animation-delay: -0.3s; animation-delay: -0.3s;}
        .container2 .circle4{-webkit-animation-delay: -0.2s; animation-delay: -0.2s;}
        .container3 .circle4{-webkit-animation-delay: -0.1s; animation-delay: -0.1s;}
        @-webkit-keyframes bouncedelay{0%, 80%, 100%{-webkit-transform: scale(0.0)} 40%{-webkit-transform: scale(1.0)}}
        @keyframes bouncedelay{0%, 80%, 100%{transform: scale(0.0); -webkit-transform: scale(0.0);} 40%{transform: scale(1.0); -webkit-transform: scale(1.0);}}
    </style>

    效果图:

    3、一个登入页面要想做好的话,也是需要很多考量的。输入号码时的判断,一键清除,还有判断语句的显示,还有友好的界面提示。(如果有机会的话,自己应该好好的写一个登入页面)

    4、下拉刷新

    5、图片上传

    (1)需要导入的文件 

    <script src="//cdn.bootcss.com/angular.js/1.5.8/angular.min.js"></script>

    <script src="js/ng-file-upload.min.js"></script>
    <script src="js/ng-file-upload-shim.min.js"></script>
    <script src="js/upImg.js" ></script>
    

    (2)html文件
