I have a JSP page which has several input fields and a servlet validates the fields when I click on the submit button and redirects to another page.
I would like to add a popup window: "all the fields are ok" after a correct server-side validation.
So I started with:
<form ="alert('success');">
<input type="submit" value="submit">
</form>
The problem is that "success" is printed even if the fields are incorrect.
I thought about setting a parameter in the protected void doPost(HttpServletRequest
request, HttpServletResponse
response, which calls an execute() function to say if things are OK or not but I do not know how to get this parameter just after the submit so I could make a conditional:
if (checkSubmitParameter == OK )
callsPopup()
Try something like this (see jsfiddle ):
<script>
function checkit(){
var val = document.getElementById('txt').value;
if(val == "good"){
alert("success");
}else{
alert("failure!");
}
}
</script>
<form onsubmit='checkit()'>
<input type='text' id="txt" />
<input type='submit' value='Submit' />
</form>
