一 关键词 ：鼠标事件的触发 可以在函数中指定让鼠标事件自动触发，而不是必须要鼠标滑过才触发，例如： main.onmouseover(); // 可以把该语句看做是鼠标滑过的模拟动作 main 是DOM元素 二 关键词 ：for..of 的兼容性问题 旧的浏览器可能不会兼容for of方式的迭代方式，所以尽量使用常规的方式来迭代数组。 三 关键词 ：function作用域问题 例子： for(var d = 0;d<10;d++){ function(){ console.log(d); //在此处，打印的d的值永远为10； `原因未知` } } 四 关键词 :元素的className 清除元素className的方法： main.className = ""; //main为获取的DOM元素 五 关键词 ：元素在元素之上 若想让元素a在元素b之上，就应该先让元素a和元素b处在同一级，然后让元素a脱离标准流。 六 line-height可以控制a元素的高度。 七 关键词 ：导航栏相邻元素display问题 在js导航栏的案例中，需要实现这样的功能：当从一级菜单滑出时，保证二级菜单不消失（前提：设置了滑出一级菜单时二级菜单消失）。 实现方法 ：为二级菜单的设置滑过她时，他自己出现。 总结 在这个案例中，整个轮播特效的部分在一个整体的div中。 图片轮播的区域又是一个div

Which could cause problem if you have buttons above or below the ad. User could accidentally click on the ad if the ad returned at the exact moment they are about to click a button. In old admob SDK I solved this by using setGoneWithoutAd(false). This way, the space will be preserved even when the ad is not returned yet. In the new SDK (Google Admob Ads SDK 4.0.4) I manage to do the same by using this quick fix: reserve the space

I have looked for a solution to creating this level of functionality but I am unable to find it. I am creating a VoIP application for iOS 8. When a user receives a call I am displaying a notification with a 12 second ringtone. While this notification is in progress if the call disconnects I want the Incoming Call notification to disappear and display a Missed Call notification immediately. This level of functionality is possible because Viber does it. Currently, I am sending a

My aim is using the navbar as the navigation for operations and putting a banner of the project above it. It will be cool if navbar is alway there in case of scrolling, but it is better for banner to disappear. How can I achieve that, any examples? 回答1: The trick is in using affix , and then you don't necessarily need to put the banner in the <header> . css: #topnavbar { margin : 0 ; } #topnavbar.affix { position : fixed ; top : 0 ; width : 100 %; } js: $ ( '
