我想验证我的动态文本字段，我使用的是javascript。
在这一行我收到错误
<aui:form name="frmaddTravelDetails" id="frmaddTravelDetails" action="<%=processActionURL.toString()%>" method="post" onSubmit="return validateAllInputBoxes(event)">
错误消息：
无法从函数或方法外部返回。
view.jsp的：
<script type="text/javascript" >

//var uniqueId=1;

答案 0 :(得分：0)
通常情况下，如果onSubmit="return myFunction()"返回myFunction，则false取消事件，如果返回true则继续。
但是你的函数什么也没有返回，我认为使用"return MyFunction()"是不恰当的。
此外，在validateAllInputBoxes您测试if(inputs[i].length==0)但输入文本对象
没有长度属性（我知道）你应该尝试测试inputs[i].value == null or inputs[i].value.length==0。
