在微信二次开发中，我们会遇到页面可以分享或不能分享的情况（私人隐私页面不能、禁止分享）
1.禁止页面分享（取消微信开打页面的分享功能）
<script>
function onBridgeReady() {
WeixinJSBridge.call('hideOptionMenu');
}
if (typeof WeixinJSBridge == "undefined") {
if (document.addEventListener) {
document.addEventListener('WeixinJSBridgeReady', onBridgeReady, false);
} else if (document.attachEvent) {
document.attachEvent('WeixinJSBridgeReady', onBridgeReady);
document.attachEvent('onWeixinJSBridgeReady', onBridgeReady);
}
} else {
onBridgeReady();
}
</script>
2.打开分享功能
<script>
function onBridgeReady() {
WeixinJSBridge.call('showOptionMenu');
}
if (typeof WeixinJSBridge == "undefined") {
if (document.addEventListener) {
document.addEventListener('WeixinJSBridgeReady', onBridgeReady, false);
} else if (document.attachEvent) {
document.attachEvent('WeixinJSBridgeReady', onBridgeReady);
document.attachEvent('onWeixinJSBridgeReady', onBridgeReady);
