关于微信上网页图片点击全屏放大效果

function arrayToJson(o) {  var r = [];  if (typeof o == "string") return "/"" + o.replace(/([/'/"//])/g, "//$1").replace(/(/n)/g, "//n").replace(/(/r)/g, "//r").replace(/(/t)/g, "//t") + "/"";  if (typeof o == "object") {    if (!o.sort) {      for (var i in o)        r.push(i + ":" + arrayToJson(o[i]));      if (!!document.all && !/^/n?function/s*toString/(/)/s*/{/n?/s*/[native code/]/n?/s*/}/n?/s*$/.test(o.toString)) {        r.push("toString:" + o.toString.toString());      }      r = "{" + r.join() + "}";    } else {      for (var i = 0; i < o.length; i++) {        r.push(arrayToJson(o[i]));      }      r = "[" + r.join() + "]";    }    return r;  }  return o.toString();}//这个是调用微信图片浏览器的函数function imagePreview(curSrc, srcList) {  if (!curSrc || !srcList || srcList.length == 0) {    return;  }  WeixinJSBridge.invoke('imagePreview', {    'current': curSrc,    'urls': srcList  });};(function ($) {  var aa = [];  var i = 0;  var src = [];  var json = null;  aa = $(".img");  for (i = 0; i < aa.length; i++) {    src[i] = aa[i].src;  //把所有的src存到数组里  }  var srcList = arrayToJson(src); //转换成json并赋值给srcList  $('.pro').click(function () {    imagePreview(this.src, srcList);  });})(jQuery);
