Re: javascript validation
 

hi again! i ran into a tutorial for javascript regarding: Regxp, then i came up with this code

  } else if(name = /^ZPR\[0-9]$/) {

      hideAllErrors();

      document.getElementById("nameError").style.display = "inline";

      document.getElementById("name").select();

    return false; 

but it doesnt work, can somebody please guide me accordingly?

below is my current validation.js

  function checkForm() {

    

  name = document.getElementById("name").value;

  email = document.getElementById("email").value;

 

  if (name == "") {

  hideAllErrors();

document.getElementById("nameError").style.display = "inline";

document.getElementById("name").select();

  return false;

  } else if (email == "") {

hideAllErrors();

document.getElementById("emailError").style.display = "inline";

document.getElementById("email").select();

  return false;

  } else if (email.indexOf("@") < 1) { //  must contain @, and it must not be the first character

hideAllErrors();

document.getElementById("emailError").style.display = "inline";

document.getElementById("email").select();

  return false;

  } else if (email.lastIndexOf(".") <= email.indexOf("@")) {  // last dot must be after the @

hideAllErrors();

document.getElementById("emailError").style.display = "inline";

document.getElementById("email").select();

  return false;  

  } else if (email.indexOf("@") == email.length) {  // @ must not be the last character

hideAllErrors();

document.getElementById("emailError").style.display = "inline";

document.getElementById("email").select();

  return false;  

  } else if (email.indexOf("..") >=0) { // two periods in a row is not valid

hideAllErrors();

document.getElementById("emailError").style.display = "inline";

document.getElementById("email").select();

  return false; 

  } else if (email.indexOf(".") == email.length) {  // . must not be the last character

hideAllErrors();

document.getElementById("emailError").style.display = "inline";

document.getElementById("email").select();

  return false; 

  

  }

  return true;

  }

 

  function hideAllErrors() {

document.getElementById("nameError").style.display = "none"

document.getElementById("emailError").style.display = "none"



  }

Re: javascript validation
 

try this

/^ZPR[0-9]{8}$/

instead of this

/^ZPR\[0-9]$/
