由 一曲冷凌霜 提交于 2020-01-09 11:46:28

问题 I found this article that looked like exactly what I wanted, but I can't seem to get it to work at all. Since it is well over a year old, I thought perhaps something may have changed, or that there might be a simpler way to do it by now. That is to say, I cannot get the method I linked above to work. I copied and pasted exactly, and used <body onLoad="javascript_needed()"> because I wasn't sure where $(document).ready(function ()... was supposed to go. I am, sadly, quite unfamiliar with
