JS 中改变confirm默认按钮提示“确定""取消"

通常用js 中confirm实现弹出对话框确定取消

<script?language="Javascript">?
function?preview()?
{?
?????var?bln=confirm("需要打印签核流程吗？")
?????if?(bln==true){}
?????else{}???
}
</script>

有的时候需要把 “确定”“取消” 替换成 “是” “否” “取消”

<SCRIPT?LANGUAGE="vbscript">???
??function?show(str)
??show=msgbox(str,3,"提示")?
??//是?6???
??//否?7???
??//取消?2???
??end?function???
</SCRIPT>???

?

如果用上language=vbscript 当鼠标划过menu的时候网页左下角会出错，如果改成javascript就OK 了?

<script?language="Javascript">?
??function?show(str)???
??{???
?????execScript("n=msgbox('"+str+"',3,'提示')","vbscript");
??????return(n);???
??}???
</script>??
<script?language="Javascript">?
function?preview()?
{????var?bln;
?????bln=show("是否要将签核过程打印在页面后?")
???????switch(bln)???
????????{?case?6:???
? ? ? ? ?//SignTR.className='';
?????????break;
?????????case?7:???
? ? ? ? ?//SignTR.className='NOPRINT';
?????????break;???
?????????case?2:?????
?????????return;}???
}
</script>?

只有“是”“否”，还有其他情况可参考vbscript的msgbox

<script?language=javascript>??
function?window.confirm(str)???
??{???
??????execScript("n = (msgbox('"+str+"',vbYesNo,'我的提示')=vbYes)","vbscript");???
??????return(n);???
??}???
??alert(confirm("重载的confirm弹出框"));???
</script>
