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(); 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;
