页面循环多个表单出错

Question

<form name="favform" action="javascript:void(0)" onsubmit="return gotofav()">
<input type="txt" name="fav" value="-1.933227,115.807851"><input type="submit" value="go" /></form>

上面这个代码会从数据库循环输出很多，导致页面表单重复无法运行，提示
；Uncaught TypeError: Cannot read property 'value' of undefined

下面是js函数
function gotofav(){Map.flyTo(document.favform.fav.value.split(','));

请问怎么解决。谢谢。

就是这样就不能运行；多个表单在一页：
<form name="favform" action="javascript:void(0)" onsubmit="return gotofav()">
<input type="txt" name="fav" value="-1.933227,115.807851"><input type="submit" value="go" /></form>

<form name="favform" action="javascript:void(0)" onsubmit="return gotofav()">
<input type="txt" name="fav" value="-1.933227,115.807851"><input type="submit" value="go" /></form>

<form name="favform" action="javascript:void(0)" onsubmit="return gotofav()">
<input type="txt" name="fav" value="-1.933227,115.807851"><input type="submit" value="go" /></form>

<form name="favform" action="javascript:void(0)" onsubmit="return gotofav(this)">
<input type="txt" name="fav" value="-1.933227,115.807851"><input type="submit" value="go" /></form>

<form name="favform" action="javascript:void(0)" onsubmit="return gotofav(this)">
<input type="txt" name="fav" value="-1.933227,115.807851"><input type="submit" value="go" /></form>

<form name="favform" action="javascript:void(0)" onsubmit="return gotofav(this)">
<input type="txt" name="fav" value="-1.933227,115.807851"><input type="submit" value="go" /></form>

function gotofav(obj){Map.flyTo(obj.fav.value.split(','))};

document.favform多个form返回的是个数组.
