光标的帖子总结（Range的使用）_javascript技巧

时间：2021-07-01 10:21:17 帮助过：3人阅读

先说说TextRange 的常用方法

collapse([bStart])
移动Range的插入点
bStart true(移到开头) false(移到末尾)

findText(sText [, iSearchScope] [, iFlags])
在Range中查找sText
iSearchScope 开始位置，负数方向搜索
iFlags 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()
选中Range

然后讲一些例子，大家也可以帮忙汇总一下，找帖子不好找，呵呵
