请问我该怎么调用，我写的代码只能实现一个js函数的功能？

Question

form action="<%=request.getContextPath()%>/duanxin/manager.jsp?oper=login" onsubmit="return validate_form(this)" method="post">
<input name="acction" type="hidden" value="2" />
用form 调用两个js函数
<script type="text/javascript">

function validate_required(field,alerttxt)
{
with (field)
{
if (value==null||value=="")
{alert(alerttxt);return false}
else {return true}
}
}
</script>

<script type="text/javascript">
function validate_form(thisform)
{
with (thisform)
{
if (validate_required(code," 用户名不能为空!")==false)
{code.focus();return false}
if (validate_required(end," 密码不能为空!")==false)
{end.focus();return false}
}
}
</script>

Answer 1

<script type="text/javascript">function validate_required(field,alerttxt){with (field){if (value==null||value==""){alert(alerttxt);return false}else {return true}}}function validate_form(thisform){with (thisform){if (validate_required(code," 用户名不能为空!")==false){code.focus();return false}if (validate_required(end," 密码不能为空!")==false){end.focus();return false}}}</script>

Answer 2

解释器是按照函数定义的先后，后定义的覆盖先定义的。如果函数来自不同的文件，按文件被include的顺序来。举例说有1.js和2.js，里面分别有fun（）的函数定义。如果html文件先include 1.js再include 2.js，那么后续对fun（）的调用就来自2.js；而如果在include 2.js之前的调用则来自1.js

很简单onsubmit="if(validate_form(this)){validate_required(this,2)}"
