[英]What is the correct way of catching an error?
How can i set a variable to the message of an error? 如何为错误消息设置变量? This is my code:
这是我的代码:
.catch(console.error).then((err) => {
var x = err.message;
)};
And i am getting this error: 我收到此错误:
Cannot read property 'message' of undefined
无法读取未定义的属性“消息”
You get the error in the catch
call: 您在
catch
调用中得到错误:
.catch((err) => {
console.error(err);
var x = err.message;
});
