Hi everyone, my problem today is that .attr which dont apply on my . 大家好，我今天的问题是.attr不适用于我的。 I want the href of "link1" update dynamically with the change of select option in "pickhour". 我希望“ pickhour”中的select选项更改动态地更新“ link1”的href。 I tried many things but Im not really smart with JS, I hope somebody will understand whats wrong, it seem to be so easy.. BUT ITS NOT ! 我尝试了很多事情，但是我对JS并不是很聪明，我希望有人能理解这是怎么回事，这似乎很容易..但不是！ >< > <
