JavaScript小技巧
- 事件源对象
event.srcElement.tagName
event.srcElement.type - 捕获释放
event.srcElement.setCapture();
event.srcElement.releaseCapture(); - 事件按键
event.keyCode
event.shiftKey
event.altKey
event.ctrlKey - 事件返回值
event.returnValue - 鼠标位置
event.x
event.y - 窗体活动元素
document.activeElement - 绑定事件
document.captureEvents(Event.KEYDOWN); - 访问窗体元素
document.all("txt").focus();
document.all("txt").select(); - 窗体命令
document.execCommand - 窗体COOKIE
document.cookie - 菜单事件
document.oncontextmenu - 创建元素
document.createElement("SPAN"); - 根据鼠标获得元素：
document.elementFromPoint(event.x,event.y).tagName=="TD
document.elementFromPoint(event.x,event.y).appendChild(ms) - 窗体图片
document.images[索引] - 窗体事件绑定
document.onmousedown=scrollwindow; - 元素
document.窗体.elements[索引] - 对象绑定事件
document.all.xxx.detachEvent('onclick',a); - 插件数目
navigator.plugins - 取变量类型
typeof($js_libpath) == "undefined" - 下拉框
下拉框.options[索引]
下拉框.options.length - 查找对象
document.getElementsByName("r1");
document.getElementById(id); - 定时
timer=setInterval('scrollwindow()',delay);
clearInterval(timer); - UNCODE编码
escape() ,unescape - 父对象
obj.parentElement(dhtml)
obj.parentNode(dom) - 交换表的行
TableID.moveRow(2,1)

//正则匹配
匹配中文字符的正则表达式： [\u4e00-\u9fa5]
匹配双字节字符(包括汉字在内)：[^\x00-\xff]
匹配空行的正则表达式：\n[\s| ]*\r
匹配HTML标记的正则表达式：/<(.*)>.*<\/\1>|<(.*) \/>/
匹配首尾空格的正则表达式：(^\s*)|(\s*$)（像vbscript那样的trim函数）
匹配Email地址的正则表达式：\w+([-+.]\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*
匹配网址URL的正则表达式：http: //([\w-]+\.)+[\w-]+(/[\w- ./?%&=]*)?
以下是例子：
利用正则表达式限制网页表单里的文本框输入内容：
用正则表达式限制只能输入中文：onkeyup= "value=value.replace(/[^\u4E00-\u9FA5]/g,'')" onbeforepaste= "clipboardData.setData('text',clipboardData.getData('text').replace(/[^\u4E00-\u9FA5]/g,''))"
1.用正则表达式限制只能输入全角字符： onkeyup= "value=value.replace(/[^\uFF00-\uFFFF]/g,'')" onbeforepaste= "clipboardData.setData('text',clipboardData.getData('text').replace(/[^\uFF00-\uFFFF]/g,''))"
2.用正则表达式限制只能输入数字：onkeyup= "value=value.replace(/[^\d]/g,'') "onbeforepaste= "clipboardData.setData('text',clipboardData.getData('text').replace(/[^\d]/g,''))"
3.用正则表达式限制只能输入数字和英文：onkeyup= "value=value.replace(/[\W]/g,'') "onbeforepaste= "clipboardData.setData('text',clipboardData.getData('text').replace(/[^\d]/g,''))"
匹配双字节字符(包括汉字在内)：[^\x00-\xff]
