条件内的Javascript通配符？

Question

I have a basic javascript conditional statement for filtering through some items, it looks like this:

if(item == var_condition) { //do this }

Now what I would like for the var_condition is, if I have a variable condition available than var_condition = my condition , but if I don't have a condition available than var_condition = * , meaning item could equal anything.

Is there a way this can be done? when I try: if(item == "*") it returns no results.

Thank you

Answer 1

尝试

if(!var_condition || item == var_condition) {//do this }

Answer 2

你可以试试：

if(item === (var_condition || item)) { /*do this*/}
