Can't make multiple if conditions in JavaScript?

Question

I have absolutely no idea why this is not working. Makes no sense to me.

This returns a \"syntax error: parse error\":

if ($(this).attr(\"id\") === \'se         


        

Answer 1

There are three different operators at play:

• =: assignment
• ==: equality
• ===: strict equality

= actually modifies a variable, so you shouldn't use it inside if statements. That is, you should use ... || opening == true) instead of ... || opening = true).
