188
189 20 . < div >< span >&< layer > 的区别？
190
191 < div > (division)用来定义大段的页面元素，会产生转行
192
193 < span > 用来定义同一行内的元素，跟 < div > 的唯一区别是不产生转行
194
195 < layer > 是ns的标记，ie不支持，相当于 < div >
196

208
209 让横条没有:
210
211 < body style = " overflow:scroll;overflow-x:hidden " >
212
213 < / body>
214

260
261 alert(checkNum( " 1232142141 " ))
