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

In JavaScript = is used to assign values, while == and === are used to compare them.

When you put opening = true in your if statement, you aren't checking if opening is true, you are setting opening to true. Try using == instead.

For example,

var x = 5;
if (x == 10) {
    alert("x is 10");
} else {
    alert("x isn't 10");
}

will display "x isn't 10", while

var x = 5;
if (x = 10) {
    alert("x is 10");
} else {
    alert("x isn't 10");
}

will display "x is 10".
