/**index.wxss**/

.swiper-tab {
 line-height: 80rpx;
 border: 1px solid #ccc;
 display: flex;
 justify-content: space-around;

 height: 100%;
 width: 100%;
 overflow: hidden;
}

.swiper-box view {
 text-align: center;
}

image {
 width: 100%;
}

js：

Page({

 /**
  * 页面的初始数据
  */
 data: {
  currentTab:0,
  tabCont: [{ "title": "tab1", "pic": "../../img/1.jpg", "index": "0" }, { "title": "tab2", "pic": "../../img/2.jpg", "index": "1" }, { "title": "tab3", "pic": "../../img/3.jpg", "index": "2" }, { "title": "tab4", "pic": "../../img/2.jpg", "index": "3" }, { "title": "tab5", "pic": "../../img/2.jpg", "index": "4" }, { "title": "tab6", "pic": "../../img/2.jpg", "index": "5" }, { "title": "tab7", "pic": "../../img/2.jpg", "index": "6" }, { "title": "tab8", "pic": "../../img/2.jpg", "index": "7" }, { "title": "tab9", "pic": "../../img/2.jpg", "index": "8" }],
 },

 /**
  * 生命周期函数--监听页面加载
  */
 onLoad: function (options) {

 },

 /**
  * 生命周期函数--监听页面初次渲染完成
  */
 onReady: function () {

 },

 /**
  * 生命周期函数--监听页面显示
  */
 onShow: function () {

 },

 /**
  * 生命周期函数--监听页面隐藏
  */
 onHide: function () {

 },

 /**
  * 生命周期函数--监听页面卸载
  */
 onUnload: function () {

 },

 /**
  * 页面相关事件处理函数--监听用户下拉动作
  */
 onPullDownRefresh: function () {

 },

 /**
  * 页面上拉触底事件的处理函数
  */
 onReachBottom: function () {

 },

 /**
  * 用户点击右上角分享
  */
 onShareAppMessage: function () {

 },
 // swiper滑动时触发bindchange事件，获取事件对象e获取当前所在滑块的 index，并将其更新至data的currentTab中，视图渲染通过判断currentTab的让对应的tab hover。
 GetCurrentTab:function(e){
  console.log(e.detail.current);
  var that = this;
  this.setData({
   currentTab:e.detail.current
  });
  // console.log("11111"+this.data.currentTab);
 },
 swithNav:function(e){
  var that = this;
  that.setData({
   currentTab:e.target.dataset.current
  });

 }
})
