swiper current="{{current}}" duration="500" style="width:480px; height:200px" catchchange="bindchangeTag" >

  <block wx:for="{{imgUrls}}">

    <swiper-item>

       <image src="{{item.bgurl}}" catchtap="onMyclick"></image>

    </swiper-item>

  </block>

</swiper>

JS代码：

var dd=3;

 var imgUrls=[

       {bgurl:"../../image/itempic.jpeg"},

       {bgurl:"../../image/testimg/test00.jpg"},

       {bgurl:"../../image/itempic.jpeg"},

       {bgurl:"../../image/testimg/test01.jpg"},

       {bgurl:"../../image/testimg/test02.jpg"},

       {bgurl:"../../image/itempic.jpeg"},

       {bgurl:"../../image/testimg/test03.jpg"},

       {bgurl:"../../image/itempic.jpeg" },

    ]

 this.setData({

imgUrls:imgUrls,

current:dd

})

滚动视图，随便点进去，都显示第一张。就是说current:dd设置失败。
