Question

I have two variables in a jquery code and if item.a not exist, it outputs a ‘null’ so i want to check if the variable exists. Here’s the code:

.append( "<a>" + item.a + ", " + item.b + "</a>" )

If there is no “item.a” it results in

null, Blabla

I tried this if / else statement but it returns nothing

.append( "<a>" + (item.a) ? item.a : + ", " + item.b + "</a>" )

Any idea?

Your attempt was close. Try this instead:

.append( "<a>" + (item.a ? item.a : "") + ", " + item.b + "</a>" )

Or, assuming you don’t want the comma when you don’t have item.a:

.append( "<a>" + (item.a ? item.a + ", " : "") + item.b + "</a>" )
