JavaScript exit method

Question

I have a JavaScript method that i want to validate a form

if the validation fails so

if (validationChecks ...... ){
    return alert("message")
}
else{
//proceed
}

however no matter what i do in the if the form still seems to submit, any ideas?

The jQuery(jquery.com) and it's validation plugin(bassistance.de/jquery-plugins/jquery-plugin-validation) will help you much. — Kamarey

you should return false after checking validation.


if (validationChecks ...... ){ 
     alert("message") 
    return false; } 
else{ 
//procced 
}

You have spelt 'return' wrong. Also, returning an alert will not work, you'll need to return false explicitly to stop the form submitting.

if (validationChecks ...... ){ 
    alert("message");
    return false; 
} 
else{ 
//procced 
}

Your validation must return false when the form is not valid, and if you're calling your validationin onSubmit, then you must make sure that you include a return statement there as well:

<form onSubmit="return validationChecks();">

You need to return false; in the case of failure
