createselectorquery

使用wx.createSelectorQuery()获取不到节点
this.$nextTick(() => {
wx.createSelectorQuery().select('#myCanvas').fields({
node: true,
size: true,
}).exec(function (res) {
console.log(res,'RES22222')
})
});

this.$nextTick(() => {
const query = wx.createSelectorQuery()
query.select('#myCanvas').boundingClientRect()
query.selectViewport().scrollOffset()
query.exec(function(res){
console.log(res)
})
});
