How to prevent transfer of values once there are some errors in the xslt file using javascript?

Question

This is my onsubmit function where i have problem. Hope you guys will help.

function editme() {
  var peru=document.editform.user_nam.value;  
  var mailu=document.editform.user_mai.value; 

if (peru==null || peru==""){  
  alert("Name can't be blank");  
  return false;  
}

if(!/(?=.{0,20}$)\S+\s\S+/.test(peru)){                                   
  document.getElementById("eredit").innerHTML="1.Value entered in the Name  field is invalid;"
}

if(!/^[\w\-\.\+]+\@[a-zA-Z0-9\.\-]+\.[a-zA-z0-9]{2,4}$/.test(mailu)){
  document.getElementById("erredit").innerHTML="2.Value entered in the E-mail field is invalid";
}

 var aa=document.getElementById("ename").value;
 var bb=document.getElementById("email").value;
 var cc=document.getElementById("sele").value;
 var tab=document.getElementById("myTable");
 tab.rows[ind].cells[1].innerHTML=aa;
 tab.rows[ind].cells[2].innerHTML=bb;
 tab.rows[ind].cells[3].innerHTML=cc;
}

Here, even if there are any validation messages, my values are getting submitted to a table.I want to stop the function where there are error messages. How to do that?

Have you tried adding return false, in to the both ifs? Like this:

if(!/(?=.{0,20}$)\S+\s\S+/.test(peru)){                                   
    document.getElementById("eredit").innerHTML="1.Value entered in the Name  field is invalid;"
    return false;
}

if(!/^[\w\-\.\+]+\@[a-zA-Z0-9\.\-]+\.[a-zA-z0-9]{2,4}$/.test(mailu)){
    document.getElementById("erredit").innerHTML="2.Value entered in the E-mail field is invalid";
    return false;
}

Also would be much helpful if you can post your whole code, so I can replicate the problem to see and work with it.

if(!/\S+\s\S+/.test(name)) using this if condition i tried to create a single space between two words.But for as u can see above by using thiscondition if(!/(?=.{0,20}$)\S+\s\S+/.test(peru)) i tried to limit the size but once i do this it is accepting the first letter even if it is lowercase which shd not happen ....if u knoe something help me out – VENKATTHERAISINGSTAR Aug 11 '17 at 09:21
