我在 JSP 页面中编写了一个 java 脚本代码,但是当我尝试提交页面时,我的 javascript 验证代码没有被触发,任何人都可以帮我解决问题吗?
这是我的代码:
<html>
<center><h3>Employee Absent Report</h3></center>
<head>
<script language="javascript" type="text/javascript">
function onFormSubmit(){
var countErrors = 0;
var strDt=document.getElementById("startdate").value;
var endDt=document.getElementById("todate").value;
var flag=false;
var eFlag = false;
if (IsEmpty(strDt)==false && IsEmpty(endDt)==true ) {
document.getElementById("divExpiryDate").innerHTML = "* Please Enter Expiry Date";
return false;
}
if (IsEmpty(strDt)==true && IsEmpty(endDt)==false ) {
document.getElementById("divStartDate").innerHTML = "* Please Enter Start Date";
return false;
}
return true;
}
</script>
</head>
<body>
<form name="form" action="FormServlet" method="get" onsubmit="return onFormSubmit(); ">
<center>
<div id="formErrors" class="error"></div>
FromDate:
<input type="text" name="startdate" id="startdate"/>
<div id="divStartDate"></div>
<br>
ToDate:
<input type="text" name="todate" id="todate"/>
<div id="divExpiryDate"> </div>
<br>
<input type="submit" value="submit"/>
</center>
</form>
</body>
</html>
