这篇博客主要介绍了如何使用JavaScript解决在打印时HTML多选框不显示选中状态的问题。通过自定义`apply`和`call`函数，以及演示如何下载文件、检查URL有效性、实现POST请求等实用技巧，文章深入探讨了JavaScript的实用功能。同时，还分享了如何创建Excel、控制光标位置、实现页面内的查找、打印设置等交互功能的实现方法。

北京时间10月6日，世界三大通讯社之一的法新社刊发图文报道，中国国脚孙继海因为在最近的世界杯预选赛中的表现，已经吸引了意大利俱乐部AC米兰和都灵队的争购。中国队只需在10月7日同阿曼队的比赛中战平就将首次进入世界杯决赛圈。图为孙继海(右)1998年12月19日在亚洲杯上的资料图片。

TextRange的常用方法
collapse([bStart])
收起选区，并移动Range的插入点
bStart
true(移到开头,default)
false(移到末尾)
expand(sUnit)
展开选区，让单位所包括的选区被包含进来
findText(sText [, iSearchScope] [, iFlags])
在Range中查找sText
iSearchScope 开始位置，负数方向搜索
iFlags 1(向后搜索) 2(整词匹配) 4(区别大小写)
moveStart(sUnit [, iCount])
moveEnd(sUnit [, iCount])
移动Range的开头或结尾
sUnit character(字) word(词) sentence(句) textedit(Range)
iCount 移动数量，默认为1
moveToPoint(iX, iY)
移动光标到坐标(iX,iY)
pasteHTML(sHTMLText)
替换Range中的html
scrollIntoView([bAlignToTop])
滚动使之在当前窗口显示
bAlignToTop
true(Range在窗口开头)
false(Range在窗口底部)
select()
让选区选中状态
事件源对象
event.srcElement.tagName
event.srcElement.type
捕获释放event.srcElement.setCapture();
event.srcElement.releaseCapture();

窗体事件绑定document.οnmοusedοwn=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)
替换CSSdocument.all.csss.href = "a.css";并排显示display:inline隐藏焦点hidefocus=true

//过滤数字
//特殊用途
//不缓存
//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：/.*|/
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：οnkeyup="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： οnkeyup="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：οnkeyup="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：οnkeyup="value=value.replace(/[\W]/g,'') "onbeforepaste="clipboardData.setData('text',clipboardData.getData('text').replace(/[^\d]/g,''))"
