I try to replace a jquery chaned function with a var but it doesnt work (synthax error)
Triing something like this:
var foo = 'next()';
$(this).+foo+.show();
Is it possible somehow to realize that? foo is a var which changes to 'prev()' in another if condition
Do it like this:
var foo = 'next';
$(this)[foo]().show();
By setting only the method name to the variable, you can use the [] notation and use the variable to retrieve the next property of the jQuery object.
This is equivalent to...
$(this)['next']().show();
which is equivalent to...
$(this).next().show();
foo.bar and foo['bar'] mean the same thing, with foo['bar'] having that advantage that you can use a variable for the key.
[foo]() to execute the method.try this:
var foo = 'next';
$(this)[foo]().show();
You have two options that I see:
var foo = next; // use the OBJECT here, not a string
$(this).foo().show();
OR
var foo = false;
if (foo)
$(this).next().show()
else
$(this).prev().show();
eval; don't. Instead, use conditionals.
