JavaScript/Hammer.js: How to detect Android pinch to zoom innerWidth?

• I want to know the innerWith/viewport width of the pinch to zoom when it's zoomed. If it's below 500 px I want to change the image with: $("img#ad").attr("src", "http://img0.www.suckmypic.net/img/1/L/mmy4jT8s/jsFiddle3.png"); I've tried something like this: var hammer = new Hammer(document.getElementById("log")); hammer.ontransformstart = function(ev) { var pziW = "test"; // Declare here the innerWidth of the pinch to zoom if (pziW < 500) { $("img#ad").attr("src", "http://img0.www.suckmypic.net/img/1/L/mmy4jT8s/jsFiddle3.png"); } }; hammer.ontransform = function(ev) { var pziW = "test"; // Declare here the innerWidth of the pinch to zoom if (pziW < 500) { $("img#ad").attr("src", "http://img0.www.suckmypic.net/img/1/L/mmy4jT8s/jsFiddle3.png"); } }; hammer.ontransformend = function(ev) { var pziW = "test"; // Declare here the innerWidth of the pinch to zoom if (pziW < 500) { $("img#ad").attr("src", "http://img0.www.suckmypic.net/img/1/L/mmy4jT8s/jsFiddle3.png"); } }; But I don't know how to declare the innerWidth of the pinch to zoom.
