自定义tabBar： <!--custom-tab-bar/index.wxml--> <view class="tab-bar"> <view class="tab-bar-border"> <view class="tab-bar-item" bindtap="xiaokaotap"> <image class="cover-image" src="{{index_img_1}}" mode="widthFix" /> <text class="cover-view" style="color:{{text_color_db}}">校考</text> </view> <view class="tab-bar-item" bindtap="liankaotap"> <image class="cover-image" src="{{index_img_3}}" mode="widthFix" /> <text class="cover-view" style="color:{{text_color_70}}">联考</text> </view> </view> </view> 引入页面后，在引入页面的js中定义数据和图片： data: { index_img_1: "/images/xiaokao_707070.png", index_img_3: "/images/liankao_dbdbdb.png", text_color_70: "#dbdbdb", text_color_db: "#707070", }, liankaotap:function(){ wx.navigateTo({ url: '/pages/liankao/liankao', }) }, xiaokaotap:function(){ } 可是，引入的页面没有显示图标图片，点击按钮，出现提示： Component "pages/liankao/liankao" does not have a method "liankaotap" to handle event "tap".
