The issue of incompatible statements with Firefox

Using a js that clicks the button to jump, the statement is very simple:

<input type="button" value="Add" onclick="('https://);" />

During the test, I found that it is available under IE but firefox cannot be used. So I added a window in front of the location, which changed to:

onclick="('');"

I found that it still doesn't work.

So I went to baidu and found an answer:

Use ="url"; instead of ('url');"

So change the source program to the following:

<input type="button" value="Add" onclick="=''';" />
