Equivalent to PHP's $_POST variable

[Tyler Smith]

Hi,

I'm trying to figure out the best solution for my e-mail submission box at my website here. Because of the predefined string methods in JS, namely match() and substring(), I want to do the following:

Test if the submission has a '@' and a '.com', '.net', '.org', '.biz', etc. in it.

Is there an equivalent method to PHP's $_GET or $_POST for JavaScript to grab the data just submitted from the input field in the form with the name 'go'?

Thanks for the help.

You can do this with the querystring (GET params), but not with post data, as that's part of the http request, which javascript doesn't have access to.

Thanks, but I still have a question about what are all of these slashes in the code?

{
  name = name.replace(/\/, "\\\[").replace(/[\]]/, \\\]);
  var regexS = "[\\?&]" + name + "=([^&#]*)";
  var regex = new RegExp(regexS);
  var results = regex.exec(window.location.search);
  if(results == null)
    return "";
  else
    return decodeURIComponent(results[1].replace(/\+/g, " "));
}

Some are escapes, and others are regex delimiters.

You can get the value with $('#go').val();
What you should do is create a function for the submit method of the form and use jquery to test the email address and return false (if it's not a valid address) to prevent the form from submitting. Something like:
$('#emailbox').submit(function(){
var email = $('#go').val();
if(validate(email){
return true;
}else{
return false
}
});
Then you will need a function called validate that takes the parameter of email and tests whether it's valid with your regex.
