to xuzuning(唠叨): 這樣還是有錯!!!<script>function outoperation()
{
strop="";
strop=strop+"<SCR" + "IPT LANGUAGE=\"JavaScript\">";
strop=strop+"function document.onmousedown(){";
strop=strop+"var obj=event.srcElement;var pobj=obj.parentElement.id;";
strop=strop+"if(obj.className==\"span\"){for(i=0;i<4;i++){if(pobj==(\"btn\"+i)){document.all(\"m\"+i).style.backgroundColor=\"menu\"document.all(\"btn\"+i).style.height=20;document.all(\"tb\"+i).style.display='';}else{document.all(\"m\"+i).style.backgroundColor=\"white\"document.all(\"btn\"+i).style.height=18;document.all(\"tb\"+i).style.display='none';}}}"; strop=strop+"}"; strop=strop+"</SCR" + "IPT>"; document.write(strop);}outoperation();</script>

多处地方缺少行结束符<script>function outoperation()
{
strop="";
strop += "<SCR"+"IPT LANGUAGE='JavaScript'>";strop += "function document.onmousedown(){";
strop += "var obj=event.srcElement;"
strop += "var pobj=obj.parentElement.id;";
strop += "if(obj.className=='span'){"
strop += "for(i=0;i<4;i++){"
strop += "if(pobj==('btn'+i)){"
strop += "document.all('m'+i).style.backgroundColor='menu';"
strop += "document.all('btn'+i).style.height=20;"
strop += "document.all('tb'+i).style.display='';"
strop += "}else{"
strop += "document.all('m'+i).style.backgroundColor='white';"
strop += "document.all('btn'+i).style.height=18;"
strop += "document.all('tb'+i).style.display='none';"
strop += "}"
strop += "}"
strop += "}"
strop += "}"strop += "alert('OK');"
strop=strop+"</SCR"+"IPT>"; document.write(strop);
}outoperation();</script>
