微信公众号分享无效

[javavip]

微信公众号做点击分享，无反应；在【微信web开发者工具】里查看JS-SDK的【info】只提示【注册：onMenuShareTimeline】，百度也找不出程序是哪里的问题……求救！！！

			wx.ready(function(){
					wx.hideOptionMenu();
					//shareTo
					document.getElementById("shareTo").onclick = function(){
						wx.onMenuShareAppMessage({
							title: '分享标题',
							desc: '分享描述',
							link: 'http://www.xxx.com/goods/item.php?id=2',
							imgUrl: 'http://www.xxx.com/images/favicon.png',
							type: '',
							dataUrl: '',
							success: function () {alert("ok"); },
							cancel: function () { alert("cancel"); },
							fail: function (res){ alert(res); }
						});
						/*
						wx.onMenuShareTimeline({
							title: '分享标题',
							link: 'http://www.xxx.com/',
							imgUrl: 'http://www.xxx.com/images/favicon.png',
							success: function () {alert("ok"); },
							cancel: function () { alert("cancel"); },
							fail: function (res){ alert(res); }
						});
						*/
						alert("s1");
					}
					//
					
				
				
			});

补充：脚本里【 wx.hideOptionMenu();】的效果出来了，隐藏了右上角菜单，也【alert("s1");】，就是分享无效
