同样的代码为什么手机上像素数据就是取不到呢？

代码片段上传麻烦看一下。

tt.createSelectorQuery()

.select("#canvas1")

.fields({

node: true,

})

.exec((res) => {

let canvas = res[0].node;

let canvasCtx = canvas.getContext("2d");

const image = canvas.createImage();

image.onload = (e) => {

canvasCtx.drawImage(image, 0, 0, imgW, imgH);

let imgData = canvasCtx.getImageData(0, 0, imgW, imgH);

console.log('imgData1=', imgData)

};

image.src = "/static/y1.png";

});
