  • 按钮样式加载等待

    使用插件Ladda,基于bootstrap的样式实现加载等待的效果:

    首先引用.css以及.js文件:

    <link rel="stylesheet" href="css/bootstrap.min.css">
    <link rel="stylesheet" href="dist/ladda-themeless.min.css">
    <script src="dist/spin.min.js"></script>
    <script src="dist/ladda.min.js"></script>

    然后添加按钮样式:

    <button class="btn btn-primary ladda-button save-all" data-style="expand-right">
           <span class="ladda-label">保存</span>
    </button>

    通过js控制UI状态:

         // Bind normal buttons
            Ladda.bind( 'div:not(.progress-demo) button', { timeout: 2000 } );
    
            // Bind progress buttons and simulate loading progress
            Ladda.bind( '.progress-demo button', {
                callback: function( instance ) {
                    var progress = 0;
                    var interval = setInterval( function() {
                        progress = Math.min( progress + Math.random() * 0.1, 1 );
                        instance.setProgress( progress );
    
                        if( progress === 1 ) {
                            instance.stop();
                            clearInterval( interval );
                        }
                    }, 200 );
                }
            });

    只用ajax表单,使用语法举例:

        $('#save-all').click(function() {
                var l = Ladda.create(this);
                l.start();
                
                var data = $('#modifyform').serialize();
                var url  = $(this).attr('href');
                $.post(url, data, function(data) {
                    if (data.code == 0) {
                        $('#error_return').text(data.msg);
                    } else{
                        $('#myModa2').modal('hide');
                        
                        window.location.reload();
                    }
                }, 'json').always(
                    function() {
                        l.stop();
                    }
                );
                return false;
            })
