TextRange的常用方法

collapse([bStart])

收起选区，并移动Range的插入点

bStarttrue(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

iFlags1(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

sUnitcharacter(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

bAlignToToptrue(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

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,''))"
