</script>

这只是代码示例，还有很多功能，但我认为错误可能与周围代码有关。我完全不知道为什么，因为我知道所有周围的函数都会执行，并且会填充 First_Array。

但是，当我单击 Proceed to Second 按钮时，onclick 属性不会执行，因为 Firebug 说 proceedToSecond 不是函数

按钮代码:

<input type="button" id="proceed" name="proceedToSecond" onclick="proceedToSecond();" value="Proceed to second form">

我遇到了同样的问题，这是因为您有一个与您的函数同名的表单。 JavaScript 似乎无法区分两者，因此您会收到“不是函数”错误。
