JavaScript - Validating Sum Of <input>
Hello all,
I am pretty new to javascript and could use some help. I am validating a page (image attached) to make sure that total hours entered do not exceed the allocated amount, which is stored in the database. I have already validated to make sure that they enter a number and that it is not greater than 8. Could some one help me with the rest? thanks so much, Joe Code: var returncode = true
var inputs = document.getElementsByTagName("INPUT")
for(var x=0; x<inputs.length; x++)
{
if(inputs[x].type =='text' && isNaN(inputs[x].value))
{
document.getElementById("hourserror").style.display = "block";
inputs[x].style.backgroundColor = '#FFCCCC';
returncode = false;
}
if(inputs[x].value > 8)
{
document.getElementById("totalerror").style.display = "block";
inputs[x].style.backgroundColor = '#FFCCCC';
returncode = false;
}
}
return returncode;
Similar TutorialsThe assignment is to take a form and determine whether or not the user has put in data into the parts of the form. We are using Javascript to validate the form input and html to create the form itself. My code was running before, but then I added a confirm user input at the bottom of the form and it stopped working. I have no idea what to do at this point. Any help would be useful. I don't have any error messages because I don't know how to test it in the firefox javascript console, if someone wants to instruct me on this i can get back to you guys with the error messages. Thanks Also, my submit button has not been running the validate program when selected. Code: <html>

I have a problem with adding new inputs to a form (if and when required), Internet Explorer is fine but in Firefox if any previous input fields are filled when the more button is clicked they get reset to blank. JS: Code: fields = 0;
function addInput() {
if (fields != 100) {
document.getElementById('input').innerHTML += "<input type='text' name='input[]' size='30' />";
fields += 1;
} else {
document.getElementById('input').innerHTML += "<br />Maximum 100 fields allowed.";
document.form.add.disabled=true;}
}
form: Code: <form action="index.php" method="post"> <div id="input"> <input type="text" name="input[]" size="30" maxlength="15" /> </div> <!-- button --> <div id="more"> <input type="button" onclick="addInput()" name="add" value="More" /> </div> <!-- // button --> <input type="submit" name="submit" value="Submit" /> </form> as usual any help is appretiated .. I am thinking this should be fairly easy but yet I am not getting far. I want to have a form with a single text imput field for a zip code. Depending on which zip code the user enters will determine which url they will be sent to. If they enter a zip code which is not in the script, they would be sent to a default url. I am also assuming this can be accomplished with javascript. Any help is greatly appreciated. Code: <img class="border" alt="googtatic_map" src="http://maps.google.com/maps/api/staticmap?center=51.454863,0.011673&zoom=13&markers=United+Reformed+Church,+111+Burnt+Ash+Road,++Lee,+London+SE12+8RG,+UK&size=250x250&sensor=true" /> I have the above code and it is not validating with the w3c validation for XHTML it has thrown up 8 errors and 14 warnings. Should I ignore them or what? As I do like my code to validate. Hi everyone, Would any of you know a cross-platform way to validate XML against XSD in JavaScript? All examples found online use MSXML, which is only available under Windows/IE. Using remote web-services is not a option, since the script should be able to run online. Cheers, Vit Hi im not good with javavscript so got some code off the net to do some rollovers, however it doesnt validate. can anyone please help me as to why this maybe?

thank Q C Hi Folks I am trying to write a js that validates a form with two text inputs. The two inputs a 'D_techA' and 'D_techB'. I just want to add up (sum) the two input fields (which must be positive numbers) and make sure that they add up to exactly 100 (not more and not less). If they do not add up to 100, then an alert should pop up that says "The two values must add up to exactly 100." I have tried and tried to write a js that does this validation (looking at numerous validation scripts posted in this forum and elsewhere) and I just cannot seem to make it work. I would very much appreciate any suggestions! Thanks! The html code for my very simple form is: <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" /> <title>Untitled Document</title> </head> <body> <form id="form1" name="form1" method="post" action=""> <label>Investment in Tech A <input name="D_techA" type="text" id="D_techA" /> </label> <label>Investment in Tech B <input name="D_techB" type="text" id="D_techB" /> </label> <p> <input name="Submit" type="submit"/> </p> </form> </body> </html> I managed to create the form that asks you to type in the information but I'm having some difficulty trying to figure out the alert to say "Thank you " after you have everything filled in and then hitting the button. my code is Code:

the help is greatly appreciated hi i need a help in java script. i have some text fields and when i enter the information in it and enter the validation button i need the results to be displayed in a box below these btns. Is it possible in Java script? Please see the attached image for some ideas. cheers Hi Guys, I use this code to validate e-mail addresses: PHP Code: // checks if the e-mail address is valid var emailPat = /^(".*\"|[A-Za-z]\w*)@(\[\d{1,3}(\.\d{1,3}){3}]|[A-Za-z]\w*(\.[A-Za-z]\w*)+)$/; var matchArray = formSignup.txtEmail.value.match(emailPat); if (matchArray == null) { alert("Your email address seems incorrect. Please try again (check the '@' and '.'s in the e-mail address)"); return false; } What i noticed today, is if a customer registers with an e-mail like: something.something@hotmail.com the first dot throws up the error, i'm not to great on regex lol any help would be appreciated thanks guys Graham Hi guys! I have tried numerous attempts in getting the Address field to work (i.e. validated). I want it to accept letters, numbers, spaces and commas! However, it won't let me! Below is the code I have provided. Code: function validateAddress(fld) {
var error = "";
var illegalChars = /[\W_]/; //
} else if (illegalChars.test(fld.value)) {
fld.style.background = 'Yellow';
error = "Your Billing address contains illegal characters!\n";
} else {
fld.style.background = 'White';
}
return error;
}
Thanks a lot! We are trying to validate a piece of code on our HTML pages and get the following message - "The text content of element script was not in the required format: Expected space, tab, newline, or slash but found < instead." The code is used to set up the Facebook tags in JavaScript, and does work by itself. However, we're trying to get it to work through validation on http://validator.w3.org Code: <script src="SiteTools.js">

I have included a brief snippet of my problem in the code already, but basically my code runs through all the if statements until it gets to the if statement about the month and validating what numbers are used. Once it completes that if statement it returns true and goes no further. However if I rearrange my code it still does not work. If anyone has some idea on what I am doing I would greatly appreciate it. I am new to javascript and have been working on this for hours upon hours trying to figure it out so any help would be greatly appreciated. Thank you. I need to get an add on JS for this form to go with the current JS that is on it I need the add on JS to Validate all the fields have been filled out and then pop up an error if any of the fields are not filled out <FORM NAME="gather"><form onclick="return check(this);"> <fieldset> </p> <table width="200" border="0" cellpadding="10"> <tr> <th scope="row"><p align="left" class="style1">First Name*</p> <p> <div align="left"><input type="text" name="data_NameFirstName2" id="data_NameFirstName2" value="[Fname]"/> </p></th> </tr> <tr> <th scope="row"><p align="left" class="style1">Last Name*</p> <p> <div align="left"><input type="text" name="data_NameLastName2" id="data_NameLastName2" value="[Lname]"/> </p></th> </tr> <tr> <th scope="row"><p align="left" class="style1">Phone*</p> <p> <div align="left"><input type="text" name="phone1" id="phone1" /> </p></th> </tr> <tr> <th scope="row"><p align="left" class="style1">Email*</p> <p> <div align="left"><input type="text" name="email" id="email" /> </p></th> </tr> </table> </p> <p> <p><span class="style5">Please confirm your contact information.</span> <p><span class="style5"> (* = required) </span> <br /> <br /> <span class="style1"> <input type = "radio" name = "rad1" value = "Contact me"> <strong> Please contact me</strong></span></p> <p> <span class="style1">Please have my personal advisor</span></p> <p class="style1">contact me as soon as possible. <br /> <br /> </p> <p> <span class="style1"> <input type = "radio" name = "rad1" value = "Send me more info"> <strong>Send me more info</strong> </span></p> <p class="style1">I'm not ready to enroll yet, but</p> <p class="style1">please continue to send me more</p> <p class="style1">information and updates about </p> <p class="style1">going back to school <br /> <br /> </p> <p> <span class="style1"> <input type = "radio" name = "rad1" value = "Remove me from your mailing list"> <strong> No thanks </strong></span></p> <p class="style1"> Please remove me from your </p> <p class="style1">mailing list. <br /> <br /> </p> <label> <input type = "button" value = "submit" onclick ="chkrads()"> </label> </fieldset> </form> <script type = "text/javascript"> function chkrads() { var chosen = "None"; var which = -1; var len = document.gather.rad1.length; for (i = 0; i < len; i++) { if (document.gather.rad1[i].checked) { chosen = document.gather.rad1[i].value; which = i; } } if (chosen == "None") { alert("No Location Chosen"); } else { } if (which == 0) {window.location = "http://www.hudsonsd.com/national2010/thankcontact.html"} if (which == 1) {window.location = "http://www.hudsonsd.com/national2010/thanksend.html"} if (which == 2) {window.location = "http://www.hudsonsd.com/national2010/thanknocontact.html"} } </script> Thanks! I have 5 radio buttons called A, B, C, D, and E in my html file. I need to validate them using javascript. If no radio buttons are selected, then a message should come up and say "none selected". I actually got this part done, and it works. However, I need to do one more thing. If radio button E and any other radio button(s) are selected simultaneously, then an error message should pop up and say "Wrong combinations." How should I go about doing this? I think I'll need a logical function to do this... thanks for any help! Hi! I am trying to check and see if three fields are empty and if they are then to alert the user saying to fill in one of the three fields. I tried this: Code: if (StreetNumber.value.length == 0) {
if (StreetName.value.length == 0) {
if (City.value.length == 0) {
alert("Please enter a street number, street name, or city.");
StreetNumber.focus();
return false;
}
}
}
and this: Code: if (StreetNumber.value.length == 0 && StreetName.value.length == 0 && City.value.length == 0) {
alert("Please enter a street number, street name, or city.");
StreetNumber.focus();
return false;
}
Neither one works. Not sure what I am doing wrong. Thanks in advance! Hello, So all I need to do is have a checkbox above the 'submit' button that the user must check before the button becomes active. Once the user checks the checkbox, then the button becomes active - and users can click on this button to get to the new page. However, I haven't found any tutorials online that handle this exactly. What I have found is example scripts that have multiple checkboxes, etc...and if I try to remove any of them from the script, it seems to mess up the functionality. So - take this for example. This would actually work perfect, if the male/female option wasn't there, and the 'reset' wasn't there either: Quote: <head> <script type="text/javascript"> function validate(form) { // Checking if at least one period button is selected. Or not. if (!document.form1.sex[0].checked && !document.form1.sex[1].checked){ alert("Please Select Sex"); return false;} if(!document.form1.agree.checked){alert("Please check the terms and conditions"); return false; } return true; } </script> </head> <body> <table border='0' width='50%' cellspacing='0' cellpadding='0' ><form name=form1 method=post action=action_page.php onsubmit='return validate(this)'><input type=hidden name=todo value=post> <tr bgcolor='#ffffff'><td align=center ><font face='verdana' size='2'><b>Sex</b><input type=radio name=sex value='male'>Male </font><input type=radio name=sex value='female'><font face='verdana' size='2'>Female</font></td></tr> <tr><td align=center bgcolor='#f1f1f1'><font face='verdana' size='2'><input type=checkbox name=agree value='yes'>I agree to terms and conditions </td></tr> <tr bgcolor='#ffffff'><td align=center ><input type=submit value=Submit> <input type=reset value=Reset></td></tr> </table> </body> I try to manually remove the 'male/female' options for this in Dreamweaver, but then the script doesn't work properly. Can anybody help me out here? Would be greatly appreciated. Thank you I want to validate two a date range using javascript, so that my program would check startdate less than end date. The below function only check the year, and it works. Code: function validate()
{
var start=document.entry.datum1.value;
year = start.substr(0, 4);
month = start.substr(5, 2);
dayval = start.substr(8, 2);
var end=document.entry.datum2.value;
year1 = end.substr(0, 4);
month1 = end.substr(5, 2);
dayval1 = end.substr(8, 2);
var myDate=new Date();
myDate.setFullYear(year,month,dayval);
var today = new Date();
today.setFullYear(year1,month1,dayval1);
if (myDate> today)
{
alert("The start date must come before the end date");
return false
}
return true;
}
But I have write a function for checking the whole date value and it didnt work. My date is in format- 2008-10-23(yyyy-mm-dd) Code: function validate()
{
var start=entry.datum1.value;
year = start.substr(0, 4);
month = start.substr(5, 2);
dayval = start.substr(8, 2);
intyear = parseInt(year, 10);
intmonth = parseInt(month, 10);
intdayval = parseInt(dayval, 10);
var end=entry.datum2.value;
year1 = end.substr(0, 4);
month1 = end.substr(5, 2);
dayval1 = end.substr(8, 2);
intyear1 = parseInt(year1, 10);
intmonth1 = parseInt(month1, 10);
intdayval1 = parseInt(dayval1, 10);
var startDate = Date.parse(intyear,intdayval,intmonth);
var endDate = Date.parse(intyear1,intdayval1,intmonth1);
if (startDate > endDate)
{
alert("The start date must come before the end date");
return false;
}
return true;
}
