JS:取值方式

//JS:取值
var a = document.a.value;
var a = document.formes[0].value;
var a = document.all("a").value;
var a = document.getElementById("a");
var a = document.forms[0].elements("a").value;


frameset 取值:
<frameset rows="135,550*" frameborder="0" framespacing="2" cols="*"><!-- 185,494* -->
  <frame name="topFrame" scrolling="1"  src="">
  <frame name="001" noresize="noresize"  src="">
</frameset>
在topFrame调001的方法：self.parent.frames['001'].btnDelete_onClick_new();


JS:跳转：
1.
function exportPrefix(url)
{var obj=window.open(url,'','');}
<a href="javascript:exportPrefix('URL')" class="button">下载</a>

2.self.location.href=url;

3.document.forms[0].submit();

	if(!reg.test(url)){
		alert("输入的IP地址格式不正确！");
		return;
	}			
}
			
if(type=='D'){
	reg=/^[a-zA-Z0-9][-a-zA-Z0-9]{0,62}(\.[a-zA-Z0-9][-a-zA-Z0-9]{0,62}){0,1}(\.[a-zA-Z]+)$/;
	if(!reg.test(url)){
		alert("输入的域名地址格式不正确！");
		return;
	}
}
