apiCloud结合layer实现动态数据弹出层

css

/** 我的二维码 begin **/
    .aui-list .wechat-media {
         3rem;
    }

    .wechat-middle {
        padding: 1.3em 3.2em 0.5em;

    }

    .ewm {
        padding: 0 2.6em 0.8em;
        text-align: center;
    }

    .ewm img {
         100%;
    }

    .ewm p {
        font-size: 0.6rem;
        padding: 0 0 1.3em;
    }

    .wechat-list:before {
        background: none;
    }

    .wechat-list:after {
        background: none;
    }

    /** 我的二维码 end **/

Dot布局隐藏

<div id="qrcode_area" style="display: none;"></div>
<script id="qrcode_tmpl" type="text/html/x-dot-template">
    <div class="aui-list aui-media-list wechat-list">
        <div class=" aui-list-item-middle wechat-middle">
            <div class="aui-media-list-item-inner">
                <div class="aui-list-item-media wechat-media">
                    <img src="{{= it.Avatar}}">
                </div>
                <div class="aui-list-item-inner">
                    <div class="aui-list-item-text">
                        <div class="aui-list-item-title">{{= it.DisplayName}}
                            {{? it.Sex == '0'}}
                            <i class="aui-iconfont aui-icon-my" style="color:#898683"></i>
                            {{?? it.Sex == '1'}}
                            <i class="aui-iconfont aui-icon-my" style="color:#1EA362"></i>
                            {{??}}
                            <i class="aui-iconfont aui-icon-my" style="color:#f44336"></i>
                            {{?}}
                        </div>

                    </div>
                    <div class="aui-list-item-text aui-font-size-12">
                        {{= it.Place}}
                    </div>
                </div>
            </div>
        </div>
        <div class="ewm">
            <img src="{{= it.QrCode}}">
            <p>扫一扫上面的二维码图案，加我好友</p>
        </div>
    </div>
</script>

api异步获取数据

var user = $api.getStorage('user');
    // 获取店铺信息
    api.ajax({
        url: BASE_REQUEST_URL+'/Customer/GetCustomerQrInfo',
        method: 'post',
        data: {
            values: {
                memberId: user.member_id,
                customerId: user.customer_id
            }
        }
    }, function(json, err) {
        if (json.result) {
            var interText = doT.template($("#qrcode_tmpl").text());
            $("#qrcode_area").html(interText(json));
        }
    });

layer获取html

// show二维码
function showQrcode() {
    var html = $('#qrcode_area').html();
    layer.open({
        type: 1,
        title: false,
        shadeClose: true,
        closeBtn: 0,
        shade: 0.6,
        area: ['280px', '55%'],
        content: html
    });
}

1.弹出内容如果是iframe就无法获取异步数据了。api无法使用。
2.通过将内容隐藏来巧妙的处理。
3.获取html，通过layer的内容布局来弹出内容。
