微信海报制作，能不能出一个详细的步骤操作视频？
通过wx:if或者hidden控制布局隐藏，这样试过么
query.select(`#${canvasId}`).fields({node: true, size: true}).exec(res => {const canvas = res[0].nodeconst ctx = canvas.getContext('2d')canvas.width = res[0].width * dprcanvas.height = res[0].height * dprctx.scale(dpr, dpr)this.ctx = ctxthis.canvas = canvas})
