Must require in) imgObj: {preLoad: 1.3, / / load time src: "http://www.wwtliu.com/sxtstu/blueberrypai/indexImg/banner1.jpg",// real picture error: require (".. / assets/error.jpg "), / / if this picture is displayed incorrectly, loading: require (".. / assets/loadding.jpg ") / / the loading process displays this figure attempt: 1, / / default number of loaded pages}, imgUrl: "http://www.wwtliu.com/sxtstu/blueberrypai/indexImg/banner2.jpg" / / add only one entry That is, the real picture}}
