JavaScript - Javascript Validation Not Stopping Submitting
I am using the following validation routine
function savenotes() { if (window.XMLHttpRequest) {// code for IE7+, Firefox, Chrome, Opera, Safari xmlhttp = new XMLHttpRequest(); } else {// code for IE6, IE5 xmlhttp = new ActiveXObject("Microsoft.XMLHTTP"); } xmlhttp.onreadystatechange = function () { if (xmlhttp.readyState == 4 && xmlhttp.status == 200) { var result = xmlhttp.responseText.split("~"); alert(result[0]) if (result[0] == "1") { // alert(result[1]); alert("should return true"); valid = true; } else { alert(result[1]); valid = false; } } } var str = "ok"; var mypost = "check.asp" // alert(mypost); xmlhttp.open("GET", mypost, true); xmlhttp.send(); return valid; } now where do I put the return so that it returns to my form if it's valid or not. It doesn't seem to work to me and the form is always submitted I am calling this with <form method=post action=admin.asp onsubmit="return savenotes()"> Similar TutorialsI have a simple form that works via a suggested results system (http://www.brandspankingnew.net/arch...uggest_v2.html) While in firefox the go button is greyed out and enter doesn't submit the form in IE pressing the enter key submits the form. Is there any way with a bit of javascript to stop IE from doing a form submission on enter but only for this form (since there are many more on the site) PHP Code: <form action="index.php" method="GET" name="qsform" id="qsform"><input type="hidden" name="p" id="p" value="compdetails" style="border:1px solid #000000;" /><input type="text" name="quicksearch" id="quicksearch" value="Find Company" style="border:1px solid #000000;" onFocus="clearText(this)" onBlur="clearText(this)" /><input type="hidden" name="cid" id="cid" value="" style="border:1px solid #000000;" /> <input type="submit" name="go" id="go" value="Go" disabled="true" /></form> The thing i want to do If any field is empty -->User will see a message to fill out the field When both field is filled out and press Submit button --> goes to thankyou.php page <html> <head></head> <body> <?php $fname = $_POST['fname']; $lname = $_POST['lname']; ?> <form action="thankyou.php" method="POST"> First Name: <input type="text" name='fname'/> <?php if(empty($fname)) echo "Please provide your First Name";?><br/> Last Name: <input type="text" name='lname'/> <?php if(empty($lname)) echo "Please provide your Last Name";?><br/> <input type="submit" value="submit" /><input type="reset" value="Clear Form"/> </form> </body> </html> thankyou.php <?php echo "Thank you $fname $lname for your time." ?> I am having trouble submitting a form after validation. Here is my script. The validation works fine its just that after the form does not submit. Code: <script language='javascript'>

Thanks in advance. I have a problem when submitting through javascript, i have used it hundred times, but i dont know why it refuses to work now, http://two.xthost.info/shailesh/test.htm Please look at the attached file in IE 6 and when you click on "Delete Selected" button, you get javascript error and the form refuses to submit the error is on line document.myform.submit(); I wonder if someone can help me. I've recently put together a new web form. The form is validated using JavaScript - it shows real-time error messages when forms are left blank, and also prevents the form from being submitted if any of the input data is invalid. The problem I have is that if JavaScript is disabled, the form cannot be submitted. At the moment I am submitting the form using the following button Code: <input type="button" value="Next" onclick="submitForm(this.form);" id="button" /> The 'onclick' event runs the 'submitForm' function, which runs a final validation check and submits the form if everything checks out. If there is invalid data in the table, an alert box pops up which prevents the form from submitting. Unfortunately, if JavaScript is disabled, the 'Next' button does nothing, as it is relying on JS to submit the form. I have tried using <input type="submit"> as well as <button type="submit">. Both of these allow the form to be submitted if JS is disabled. Unfortunately, when JavaScript IS enabled, the validation gets bypassed - the alert box still shows up but once you click 'OK' the form gets processed anyway. Can anyone suggest a solution? I am planning to write server-side validation in PHP as a backup but would prefer it if my JavaScript validation would work in it's entirety and the PHP simply be in place as a last line of defence for when JS is disabled. Thanks! I have created a small file where I check if the passwords entered in the code match or not, if they do not match, the button that links to the next webpage should not work(allow them to go to the next wepage). ive tried various websites to help me try and solve this but I just dodont understand what they are doing. I'm very new to programming btw here is some example code: Code: !doctypeHTML
<html>
<script>
//lets just pretend that ive already done all the .getelement by id stuff to get the code things
//suppose the person did not write anything in the form, an error will get pushed(alerted basically)
if(!form['password'].value)
error.push('Missing Password');
<form>
<label>Password<br><input type="password" name="password"></label>
<label>Confirm Password<br><input type="password" name="confirm"</label>
</form>
</html>
now how would I make the submit button not submit if there are errors? please be as simple as possible, I am new to this! Consider the following piece of code: PHP Code: <form method='post' name='myform'> <input type='submit' name='sub' value='submit 1' /> <input type='submit' name='sub' value='submit 2' /> <a href='javascript:document.myform.submit();'>submit 3</a> </form> <?php echo "You clicked ".$_POST["sub"]; ?> So if you click "submit 1", the output will be You clicked submit 1. And if you click "submit 2", the output will be You clicked submit 2. That's obvious. But ... what do I need to do to pass the key/value pair "sub" = "submit 3" to the server via POST when I click on the hyperlink showing "submit 3" - so that the output is You clicked submit 3 (i.e. so that $_POST contains "submit 3" referenced to index "sub"). I've tried <a href='javascript: a = {"x" : 1}; document.myform.submit(a);'>submit 3</a>, but that doesn't cause a to be passed via POST. Hello, I have the following DIV tag Code: <div id = "cbContainer"> </div> The div is initially hidden as the display is set to none. I have one text input in my form. Depending upon the changed text in that textbox, there is a javascript function which creates a list of checkboxes and by using the innerHTML, the above div is filled up with the check boxes like shown in the code below: Code: var chkboxes = '';
for(var r = 0; r < related.length; r++)
{
chkboxes = chkboxes +
'<div class ="versionswidth">'+
'<input type="checkbox" name="version" value = related[r] />'+ related[r] +
'</div>';
}
var div = document.getElementById("cbContainer");
div.innerHTML = chkboxes;
div display is then set as "block" which makes the div visible. The problem is that on form submission, the input of selected checkboxes is not submitting. I will be grateful for any help. Thank you. Code: // Values for fading
var fadeBy = 10; //Amount to fade by
var fadeTime = 120; //Time in milliseconds to fade.
var ie_counter = 0; //Counter for crappy IE.
var fade_to = 70;
function fader(obj) {
var div = document.getElementById(obj);
//Object details
var opacity = div.style.opacity * 100 + fadeBy; //Fade (FF)
ie_counter = ie_counter + fadeBy;
var opacity_ie = div.style.filter = "alpha(opacity=" + ie_counter + ")"; //Fade (IE)
div.style.opacity = opacity / 100;
if ( ie_counter != fade_to || opacity != fade_to ) {
setTimeout( "fader('" + obj + "')", fadeTime );

The loop stops for firefox (good browser), but not for internet explorer for some reason :/ Apart for the fact that IE is crap why is this? as I have no idea if this will boil down to a JS problem, or a CSS problem, I've posted this to both forums. If some enterprising moderator would like to consolidate them, have at ye! Using javascript I've made a simple drag and drop interface for a backend component. Elements are dragged from a list at right into a main area. The elements are organized as a list (<ul><li>). Each has a mouse down listener which flicks on the visibility of a div (that mirrors the appearance of the named <li>) and then follows the mouse as long as it is needed. All is peachy... ... BUT THEN !!! ... As one might predict, the dragging action selects whatever content comes between the list item where the drag started and the placement where the drag ends. It's ugly and distracting; furthermore it changes my nice 'pointer' cursor to a 'text' cursor. I don't want to have to disable selecting for the entire page (nor do I know of a slick, elegant way to accomplish this) and I've tried all sorts of other hackery: cover up divs were especially fail-tastic. Hoping someone out there's cleverness gland can help me with this one. Excerpt from the site below to give an idea of layout: elements of the orange list at right get dragged into the main area in the middle I can't link to the site directly, sorry, I don't have a version ready that doesn't modify existing databases.

I am new to this forum.. and I am hoping to get help with this javascript validation for my form for my assignment. trying to validate multiple fields. I have never done javascript, so with my limited understanding from Google, I put together code snippets. Problems: 1. How can I get one message box when the user presses submit indicating all failed validation at one time 2. The expired credit card validation doesnt work 3. Cant seem to find a good "confirm password" script 3. The form does not submit if all the fields are correct. <script language="javascript"> <!-- function checkAge() { var bday=parseInt(document.forms[0].txtBday.value); var bmo=(parseInt(document.forms[0].txtBmo.value)-1); var byr=parseInt(document.forms[0].txtByr.value); var byr; var age; var now = new Date(); tday=now.getDate(); tmo=(now.getMonth()); tyr=(now.getFullYear()); { if((tmo > bmo)||(tmo==bmo & tday>=bday)) { age=(tyr-byr) } else { age=(tyr-(byr+1)) } if (age<18) { alert ("you must be over 18 years"); return false; } else { return true; } } } //--> function checkEmail() { var x=document.getElementById("email").value; var atpos=x.indexOf("@"); var dotpos=x.lastIndexOf("."); if (atpos<1 || dotpos<atpos+2 || dotpos+2>=x.length) { alert("Not a valid e-mail address"); return false; } { return true; } } function onlyNumbers(evt) { var e = event || evt; // for trans-browser compatibility var charCode = e.which || e.keyCode; if (charCode > 31 && (charCode < 48 || charCode > 57)) return false; { return true; } } function checkCardNumber() { var x = document.getElementById("cardNumber").value; if (x.length<16) { alert("Your Credit Card Number must be 16 digits"); return false; } { return true; } } function checkSecurityCode() { var y = document.getElementById("securityCode").value; if (y.length<3) { alert("Your Security number must be three digits"); return false; } { return true; } } function ValidateExpDate() { var ccExpYear = 20 + $F('<%= expYear.ClientID%>'); var ccExpMonth = $F('<%= expMonth.ClientID%>'); var expDate=new Date(); expDate.setFullYear(ccExpYear, ccExpMonth, 1); var today = new Date(); if (expDate<today) { alert("card expired"); // Credit Card is expire return false; } else { // Credit is valid return true; } } function runall() { checkAge(); checkEmail(); checkCardNumber(); checkSecurityCode(); { return false;} } </script> Hi. I am trying to do some sim[ple form validation using javascript. I have a simple html file Code: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>Send Card</title> <script language="JavaScript" src="gen_validatorv31.js" type="text/javascript"></script> </head> <body> <form action="getName.php" onsubmit="return validate_form(this);"> Receiver (To): <input type="text" name="name"><br> Sender (From): <input type="text" name="sender"><br> Email: <input type="text" name="email"><br> <input type="submit" value="Submit"> </form> </body> </html> Which calls up my javascript and php file (The php file should only be used when the javascript has found no errors). Now I have a js file which does some validation Code: <script type="text/javascript">
function validate_required(field,alerttxt) {
with (field) {
if (value==null||value=="") {
alert(alerttxt);
return false;
}
else {
return true;
}
}
}
function validate_email(field,alerttxt) {
with (field) {
apos=value.indexOf("@")
dotpos=value.lastIndexOf(".")
if (apos<1||dotpos-apos<2) {
alert(alerttxt);
return false;
} else {
return true;
}
}
}
function validate_form(thisform) {
with (thisform) {
if (validate_required(name,"Please specify your name!")==false) {
name.focus();
return false;
}
if (validate_required(sender,"Please specify the receivers name!")==false) {
sender.focus();
return false;
}
if (validate_required(email,"Email must be filled out!")==false) {
email.focus();
return false;
}
if (validate_email(email,"Not a valid e-mail address!")==false) {
email.focus();
return false;
}
}
}
</script>
When I run it on my server, I get the form and enter nothing into it, I just click submit. However, it goes straight to the php file and brings up my flash movie, which it shouldnt do. When nothing is entered, the js file should return the error. I thought I had everything set up correctly, but obviously not. Can someone see where I am going wrong? cheers 1.I want to retain the value of the item selected from the drop down list even if the validation fails 2. The input element should be hghlighted red in colour which fails the validation <html> <script type="text/javascript"> <!-- function validate_form1 ( ) { valid = true; if ( document.contact_form1.question1.value=="" || document.contact_form1.question2.value == "" ) { alert ( "Select at least one option." ); //document.getElementById("question1").focus(); document.getElementById('contact_form1').question1.focus(); valid = false; } return valid; } function validate_form2 ( ) { valid = true; if ( document.contact_form2.question1.value=="" || document.contact_form2.question2.value == "" ) { alert ( "Select at least one option." ); //document.getElementById("question1").focus(); valid = false; } return valid; } //--> </script> <table border="5" width="300"> <tr> <td> <form name="contact_form1" action="DBsaving.php" method="post" onSubmit="return validate_form1 ( );"> 1.

Faculty ID : <textarea name="comments" rows="2" cols="4"></textarea> <input type="submit" value="Submit" /> </form> </td> </tr> </table> </html> I have a validation issue. I need the input fields to highlight yellow if no text has been entered and when the form is submitted the error message displays to check the highlighted fields. I get the input boxes to highlight when there is no text but on submit the form goes to the next page without the error alert message. Any suggestions would be appreciated.
