 white-space: nowrap;
 position:fixed;
 z-index:10;

使用自定义组件
使用已注册的自定义组件前，首先要在页面的 json 文件中进行引用声明。此时需要提供每个自定义组件的标签名和对应的自定义组件文件路径：
pages/order-list/index.json


{
 "navigationBarTitleText":"订单列表",
 "usingComponents": {
 "slideTab": "../../components/navigator/index"
 }
}


这样，在页面的 wxml 中就可以像使用基础组件一样使用自定义组件。节点名即自定义组件的标签名，节点属性即传递给组件的属性值。

 <slideTab tList="{{statusType}}" bind:changeCurrent="swichNav" currentTab="{{currentType}}" >
 <swiper current="{{currentType}}" duration="300" bindchange="bindChange" style="height: {{windowHeight-35}}px;margin-top:35px;">
 <block>
  <swiper-item wx:for="{{list}}">
