Can you please help me? Hello all, I have a form that submits a POST request when data is submitted. A Servlet then processes this POST request and a JavaBean is used to make some calculations. The HTML response is not generated within the Servlet but instead I forward the request to a JSP to generate the response. - This all works fine, thankfully. However, I am stupidly suck trying to validate the form on the client side with a JavaScript function before the form is submitted. Here is my index.jps: Code: <%--

Regardless of whether incorrect input is given, the data is still POSTed to the server and calculated on or a Server Side error is given. Am I correct in calling the function onClick? The validation essentially needs to be so that: - Student field contains a string - Score1, Score2, Score3 and Score 4 contain a number between 0 and 100 Any help is most appreciated, Cheers, Beetle. Hi.. I have form and i want to input data using barcode and it will display on textbox and after input on the first textbox the focus will go to next textbox untill it will go on the last textbox and on the last textbox it will automatically save the data's on the database. How is it possible? here is my sample code: Code: <?php
error_reporting(0);
date_default_timezone_set("Asia/Singapore"); //set the time zone
$con = mysql_connect('localhost', 'root','');

Hello. I've been teaching myself HTML and CSS for a while, and now I've moved into the world of Javascript (but I'm still very much a beginner). For practice, I've been building a sample sign up form for a mock website, and I'm having problems with the birthdate section. The idea I had was to have MM, DD, and YYYY be the default values of my 3 textboxes (as an example for users), then set the value to nothing when the box gained focus. That all works fine, but I ran into problems when I tried to write an if statement to set the value back to MM, DD, or YYYY if the value was still nothing when the user clicked away. As it is now it just replaces the text inputted into the textbox (which of course is not good). Any ideas for what the problem might be? Code: <form name="signup" action="javascript:void(0);" method="post">
<table>
<tr>
<td>Date Of Birth:</td>
<td>
<input name="DOBmonth" type="text" value="MM" size="2" style="color: #555555;" onFocus="clearDOBmonth()" onBlur="restoreDOBmonth()" />
<input name="DOBday" type="text" value="DD" size="2" style="color: #555555;" onFocus="clearDOBday()" />
<input name="DOByear" type="text" value="YYYY" size="4" style="color: #555555;" onFocus="clearDOByear()" /></td>
</tr>
<tr>
<td></td>
<td><button name="Submit" type="submit" style="font-size: 1em;">Sign Up</button></td>
</tr>
</table>
</form>
<script type="text/javascript" language="javascript">
<!--
document.signup.DOBmonth.value="MM";
document.signup.DOBday.value="DD";
document.signup.DOByear.value="YYYY";
function clearDOBmonth() { document.signup.DOBmonth.value="";}
function clearDOBday() { document.signup.DOBday.value="";}
function clearDOByear() { document.signup.DOByear.value="";}
function restoreDOBmonth()
{
if ('document.signup.DOBmonth.value = ""')
{
document.signup.DOBmonth.value = "MM";
// alert(document.signup.DOBmonth.value);
}
}

Another side question, if I set a variable equal to the value of a textbox, then change the value of the variable, does that also change the value of the textbox? or is the variable no longer associated with the textbox. Example: Code: var a = document.form.textbox.value; a = blue; does document.form.textbox.value = blue? or is var a now completely independent of the textbox value? Thanks! I have a group of checkboxes named "list[]". I want to validate that at least one is checked. How can I do this?
All, I have a page that has some checkboxes in it. I have the following function for that: Code: function checkbeforesubmit(field)
{
for (var i = 0; i < field.length; i++){
if(field[i].checked){ // if a field is checked form is submitted
alert("You have checkboxes that are selected. Add the photos before you go to the next set of pictures!");
return false;
}
}
return true; // if no fields are checked form not submitted
}
I then a link to go to the next page and I want to check to see if any checkboxes are selected before I go to the next page. I try and check this by doing this: Code: onClick="checkbeforesubmit(document.photos.elements['picbigid[]'])" It does the check and says that a checkbox is selected but will still go to the next page anyway. How can I stop it from going to the next page? Thanks! Is there a y regular expression which we can use in JavaScript to validate URL? Or any other type of validation to validate URL which has http or https?
How do I fix the problem that autocomplete does not validate, I have heard before that there is a dirty way to do this but did not want to do this before, but now feel i must as my boss wants the site error free ! does anyone know how I do this ? I am trying to create an onChange action that will validate that confirmation checkbox has been checked, and if not, popup an alert message and put the focus on the checkbox input and change the class of the container DIV to "highlight". Here is the form, with the 'onchange' trigger: Code: <form id="checkout" name="my_form" method="post" action="!---SCRIPT_NAME---" onsubmit="return validForm(this);"> <div id="verification" class="aligncenter required"> <input type="checkbox" id="verified" name="verified" value="" /> <label for="verified">YES</label>, the items and quantities shown above are correct.</div> <div class="required"><label for="name">Name:</label><input id="name" name="contactname" type="text" class="L" onchange="" /></div> <div class="required"><label for="company">Company Name:</label><input id="company" name="company" type="text" class="L" /></div> <div class="buttonRow"><input type="submit" name="VERIFY" class="btn red" value="Continue" /></div> </form> And here is my javascript code: Code: function verifyOrder() {
if (document.my_form.verified.checked != "true") {
alert("Please verify the contents of your order");
document.my_form.verified.focus();
getElementById('document.my_form.verification').className='highlight'
return false;
}
}
But this is not working and generates errors in firebug. What am I doing wrong? Thanks!! Please see my Booking Form here http://www.n-v-m.co.uk/Booking.html The form is very nearly finished but I have no experience with JavaScript at all so I am hoping somebody can tell me how to do the finishing touches. All I require is: 1- On clicking the 'Submit order' button I would like the browser to check to see if the 'Is Vehicle roadworthy with full M.O.T.:' List/Menu is set to 'Yes' and if not it needs to return an alert stating it must be set to 'Yes' to proceed... Somebody kindly helped show me how to do the alert before so this is working, but, the problem at the moment is after clicking 'OK' to close the alert, the form is still submitted. At this point instead of the form being submitted I would just like the browser to return to the form. 2- There is a checkbox on the bottom of the form that states 'I agree with the Terms and Conditions'... To be able to proceed with a booking I need the customer to check the box... On clicking 'Submit order' if the box isn't checked I would like an alert to appear and the form not to be submitted. 3. When both the above criteria have been met and the form is ready to submit... I would like the browser to re-direct to http://www.n-v-m.co.uk/Thankyou.html which is a page I have already created on my server. Thanks for taking your time to read this... If it helps I have posted both my HTML and PHP codes below: Booking.html Code: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

I am trying to make validation for a form but the bit I am stuck on now is: Code: <input class="submit" type="submit" value="Submit" id="submit" name="submit" onclick="return validate();" /> Do I have to add 'verify' instead of the 'validate' I mean is this a set thing in JS as I want it to go to the JavaScript code which is validate.js I should add that the form is XHTML and there is also a captcha with it. So I would not know how to add the onsubmit to the beginning of the form. Hi, i have a problem to validate time range in javascript. i've search in the website and found some example. below is the my coding Code: function timeCheck(){
branchCode = <%=sessionUser.getBranchCode()%>;
var d = new Date();
var curr_hour = d.getHours();
var curr_min = d.getMinutes();
if (curr_min < 10){
curr_min = "0" + curr_min
}
var currtime = curr_hour + ":" + curr_min;
if(branchCode >= 1 && branchCode <= 5){
st = "7:30"; et = "9:00";
} else if(branchCode >= 6 && branchCode <= 10){
st = "9:01"; et = "10:30";
} else if(branchCode >= 11 && branchCode <= 15){
st = "10:31"; et = "12:00";
} else if(branchCode >= 16 && branchCode <= 20){
st = "12:01"; et = "13:30";
} else if(branchCode >= 21 && branchCode <= 26){
st = "13:31"; et = "15:00";
} else if(branchCode >= 27 && branchCode <= 31){
st = "15:01"; et = "16:30";
} else if(branchCode >= 32 && branchCode <= 71){
st = "16:31"; et = "18:00";
} else {
st = "6:30"; et = "19:00";
}
if(validate_time(currtime,st,et)){
alert("Cannot access this page");
location.href='<%=request.getContextPath()%>/security/welcome.do';
}
}
function validate_time(currtime,st,et ){
currtime = currtime.split(/:/);
st = st.split(/:/);
et = et.split(/:/);
return (
currtime[0] < st[0]
|| currtime[0] > et[0]
|| (currtime[0] == st[0] && currtime[1] < st[1])
|| (currtime[0] == et[0] && currtime[1] > et[1])
);
//return TRUE if time not in range
}
i want to control user's access to the page. they can only access within the range given. example: current time = 10:14 st = 9:01 et = 10:30 When I test, the currtime[0] < st[0] return true. I don't understand why the statement return true. can someone help me? Thanks in advance. Good Afternoon All, I am slowly learning how to validate forms and the next topic I'm learning is the phone feature! My code isn't working and not sure why! I read other opinions and tried to follow some templates but again.. Nothing is working out for me.. Here is the code function validatePhone(fld) { var stripped = document.validatePhone.phoneNumber(/[\(\)\.\-\ ]/g, ''); if (document.validatePhone.phoneNmbr == "") { alert("Do not leave this field blank"); } else if (isNaN(parseInt(stripped))) { alert("Only enter numerical digits only"); } else if (!(stripped.length == 10)) { alert("No More or Less than 10 Digits"); } return error; } <body> <form name="validatePhone" action="" method="get"><br /> <br /> <input type="text" name="phoneNumber" value="" onClick="return validatePhone(fld)"> <br /> <br /> <input type="button" name="button" value="Validate Phone Number" > </form> </body> </html> If you have any suggestions or can provide links of how I can 1-Provide an alert if the field is blank 2-Provide an alert if non numerical digits are entered 3-Provide an alert if more than 10 digits are entered I think I am on the right track but need more of a push.. I'm not seeking a solution, just information to get me on that right track as I am extremely confused. Also.. I feel like I should be using a isDigit function? hello i am trying to do a validation form but i ended up with one that only works for chrome, not on IE not on Firefox! don't know why!!! and another problem it looks like that the return false doesn't even work, it proceeds to the next page anyway [HTML]function validate_required(field,alerttxt) { with (field) { if (value==null||value=="-1") { alert(alerttxt); return false; } else { return true; } } } /*function alertt(thisform) {alert(thisform);}*/ function validate_form(thisform) { //alert('hi'); with (thisform) { if (validate_required(i_am_a,"i_am_a must be filled out!")=="-1") {i_am_a.focus(); return false;} } [/HTML] [HTML]<form method="post" action="index.php?page=step2" onsubmit="return validate_form(i_am_a.options[i_am_a.selectedIndex].value);"> <table class="text"> <tr> <td class="text">أنا</td> <td> <select name="i_am_a" id="i_am_a"> <!--onchange="validate_form(i_am_a.options[i_am_a.selectedIndex].value);">--> <option selected value="-1">الرجاء التحديد</option> <option value="MSW">رجل يبحث عن إمرأة</option> <option value="WSM">إمرأة تبحث عن رجل</option> </select> </td> </tr><tr class="submit"> <td> </td> <td> <input type="submit" value="إنضمم الآن مجانا" /> </td> </tr> </table> </form>[/HTML] I have this script to validate contact form fields. It works fine for checking that fields are not blank. I added the valid email code, which I copied from the w3schools web site. But, it does not work. I am confused about how to reference the email form field name. That is really the only thing I changed, that is, I added the frm.elements to the email variable. Can anyone please help? Thanks! Code: function validate_form(frm)
{
frm.elements.name.className = "input";
frm.elements.email.className = "input";
frm.elements.subject.className = "input";
frm.elements.comments.className = "input";
var errors=0;
//
// NAME cannot be blanks
//
if (isBlank(frm.elements.name.value)) {
frm.elements.name.className = "inputreq";
errors++;
}
//
// EMAIL ADDRESS cannot be blanks
//
if (isBlank(frm.elements.email.value)) {
frm.elements.email.className = "inputreq";
errors++;
}
//
// SUBJECT cannot be blanks

if (isBlank(frm.elements.subject.value)) {

errors++;
}
//
// COMMENTS cannot be blanks

}
function isBlank(value)

}
// Validate email address
function validate_email(field,alerttxt)
{

{
apos=value.indexOf("@");
dotpos=value.lastIndexOf(".");
if (apos<1||dotpos-apos<2)
{alert(alerttxt);return false;}
else {return true;}
}
}
How do I validate that one of the below buttons is selected? Code: <input type="radio" name="car" class="radio" value="YES" >Yes <input type="radio" name="car" class="radio" value="NO"> No The below code works ok but need our help to get it perfect. I want the function to validate that after the "@" the user types "wendys.com". Code: <html>

I need help please. I'm trying to validate when a user selects an item from the equipment select list they must select a reason code as to why they are ordering the item. This must work across all rows. Also the field to the left of the equipment select list should allow the user to key in the item # of the part and the select list automatically gets selected with the part. How the heck do I do this. I tried the functions I have included but they suck! Please help me Tracy Code: <script>
function validateReason(){
var tr, i=1;
while(tr=document.getElementById('Child'+(i++))){
var txtV=tr.getElementsByTagName('input')[0].value
var selS=tr.getElementsByTagName('select')[0].selectedIndex;
if(txtV.length>0&&selS==0){alert('If you enter a quantity you must select a reason!');return false}
}
}
function change_uids(uid){
var uids = document.getElementById("uids");
for (var i=0; i<uids.options.length; i++){
if (uids.options[i].value == uid.value){
uids.options[i].selected = true;
break;
}
}
}
</script>
