js querySelector选#ID报错 

code:
document.querySelector("#02b51fd4-c350-65d3-c59a-cfdc5a538066") 
err:
Uncaught DOMException: Document.querySelector: '#02b51fd4-c350-65d3-c59a-cfdc5a538066' is not a valid selector
but:
document.getElementById("02b51fd4-c350-65d3-c59a-cfdc5a538066")  -> have no error

总结：id不能是数字开头，不然使用选择器querySelector就会报错
