Given the following four propositions:

1. The minimum value of the function $y=\sin ^{2}x+ \dfrac {3}{\sin ^{2}x}$ is $2 \sqrt {3}$;
2. Given $f(x)= \dfrac {x- \sqrt {11}}{x- \sqrt {10}}$, then $f(4) < f(3)$;
3. The odd function $f(x)$ defined on $R$ satisfies $f(x+1)=-f(x)$, then $f(2016)=0$;
4. The function $y=\log _{a}(2+a^{x})(a > 0,a\neq 1)$ is an increasing function on $R$.
