- 当前 Bug 的表现（可附上截图）
把 let result= await promise; 它去掉就能执行循环了。我上传多张图，只能上传成功一次。for循环执行了一次
- 预期表现
我是想把异步变成同步，解决顺序问题
- 复现路径
- 提供一个最简复现 Demo
chooseImage22:function(){
var that = this;
var user_id = wx.getStorageSync('userid');
wx.chooseImage({
count: 6, // 默认9
sizeType: ['compressed'], // 可以指定是原图还是压缩图，默认二者都有
sourceType: ['album', 'camera'], // 可以指定来源是相册还是相机，默认二者都有
success: async function (res) {
// 返回选定照片的本地文件路径列表，tempFilePath可以作为img标签的src属性显示图片
//var tempFilePaths = res.tempFilePaths[0];
var tempFilePaths = res.tempFilePaths;
var imgs1 = that.data.imgs1;
//console.log('tempFilePaths.length');
//console.log(tempFilePaths.length);
for (var i = 0; i < tempFilePaths.length; i++) {
if (imgs1.length >= 6) {
that.setData({
imgs1: imgs1
});
// return false;
} else {
//imgs1.push(tempFilePaths[i]);
}
}
that.setData({
imgs1: imgs1

console.log('tempFilePaths.length');
console.log(tempFilePaths.length);
