1.API
百度百科:API(application programming interface,应用程序编程接口)是一些预先定义的函数,目的提供应用程序与开发人员基于某软件或硬件得以访问一组例程的能力,而又无需访问源码,或理解内部工作机制的细节.
API除了有"应用程序接口"的意思外,还特指API的说明文档,也称为帮助文档.
API帮助文档就是对这些函数写的文档,帮助开发人员了解函数的使用方法和功能.在JAVA中,API帮助文档体现形式为javadoc文档,可以方便查阅接口说明及类说明等内容,可以帮助希望使用你的接口的使用者了解你的接口并方便了解你的接口特性.
2.button的用法(和input相比)
定义和用法:
在button元素内部,可以放置内容,比如文本或图像.这是buttion和input创建的按钮之间的不同之处.
唯一禁止使用的元素是图像映射,因为它对鼠标和键盘敏感的动作会干扰表单按钮的行为.
请始终为按钮规定type属性.Internet Explorer的默认类型是"button",而其他浏览器中(包括W3C规范)的默认值是"submit".
浏览器支持:
所有主流浏览器都支持
重要事项:如果在HTML表单中使用button元素,不同的浏览器会提交不同的值.Internet Explorer将提交
可选的属性:
属性 | 值 | 描述 |
name | name | 规定按钮的名称 |
type | button reset submit | 规定按钮的类型 |
value | text | 规定按钮的初始值 |
标准属性:id,class,title,style,dir,lang,xml:lang,accesskey,tabindex
事件属性:onfocus,onblur,onclick,ondblclick,onmousedown,onmouseup,onmouseover,onmousemove,onmouseout,onkeypress,onkeydown,onkeyup
注意事项:
在使用
1.通过$('#customBtn').val()获取
<button id="customBtn" value="test">按钮</button>
中value的值,在IE(IE内核)下这样用到得的是值是“按钮”,而不是“test”,非IE下得到的是“test”。
2.无意中把
不要把
