JavaScript - Help Adding Validation For Image Upload Field
Hello Everyone,
I need to add some sort of validation that will only allow users to upload .jpg files. I really need to add this to an existing script I've already written. I've seen scripts and tutorials that add the jpg validation but only incorporate the image field of the form. I need the script to validate several forms in the field, not just one. When I try to add validation for the jpg field to the follow script everything stops working. Can someone please point me in the right direction? Thanks! Code: <form id="uploadForm" method=post class="upload" action=submit_script.php enctype='multipart/form-data' onsubmit="return validate_form(this)"> <p><b>First Name</b><br/> <INPUT TYPE="TEXT" NAME="name_first" size="40"></p> <p><b>Last Name</b><br/> <INPUT TYPE="TEXT" NAME="name_last" size="40"></p> <p><b>School Name</b><br/> <INPUT TYPE="TEXT" NAME="name_school" size="40"></p> <p><b>Your School E-Mail</b><font class="super">1</font><br/> <INPUT TYPE="TEXT" NAME="school_email" size="40"></p> <p><b>Your File</b><font class="super">4,5</font><br/> <input id="userfile1" name="userfile1" type="file" size="30"></p> <p><input name="upload" type="submit" class="box" id="upload" value="Submit Your Poster" onClick="YAHOO.example.container.wait.show();"></p> </form> Code: function validate_required_field(field,alertText) {
with (field) {
if (value==null||value=="") {
YAHOO.example.container.wait.hide();
alert(alertText);
return false;
}
else {
return true;
}
}
}
function validate_email(field,alertText)
{
with (field) {
apos=value.indexOf("@");
dotpos=value.lastIndexOf(".");
if (apos<1||dotpos-apos<2) {
YAHOO.example.container.wait.hide();
alert(alertText);
return false;
}
else {
return true;
}
}
}
function validate_form(thisform) {
with (thisform) {
if (validate_required_field(name_first,"Please enter a value in the 'First Name' field before continuing")==false) {
name_first.focus();
return false

Similar TutorialsHey all. I have a simple validation I need to do. I need to just make sure that a Checkbox is checked, and that a Text field has content. Sounds simple but I cannot find any thing that has a check and a text field. Here what I have. Can I modify this script to do this? A Checkbox MUST be checked and Text field MUST be filled out. This currently does the text field fine, but no Checkbox obviously. How can I add a checkbox validation to this? Thats it. Any help is appreciated. Code: <script type="text/javascript">
var textFields = ["digsig"];
function validateForm( )
{
var oops = ""; // must initialize this!
var form = document.sig;
for ( var t = 0; t < textFields.length; ++t )
{
var field = form[textFields[t]];
var value = field.value.replace(/^\s+/,"").replace(/\s+$/,""); // trim the input
if ( value.length < 1 )
{
oops += "You MUST enter your Digital Signature";
}
}
if ( oops != "" )
{
alert("ERROR:" + oops);
return false;
}
}
}

Hi, I'm having trouble getting this code to work. It needs to check if the user has entered the correct characters into a field. A valid word should have a P at the start, and contain a J somewhere in it. If the word is valid, a box pops up saying "OK" once the user has clicked the ValidateWord button. It also needs to keep this kind of structure (ie. a while construct & validated through pressing a button). This is purely for personal education about performance of "while" constructs for field validation. Any help is hugely appreciated. Hello, I am trying to create a function that tests to see if the text field that I create in my markup contains numbers. Please help. Thank you. Hi, I want to pop up message incase of validation failure of form field. If I use document.write("name shold be between 2 to 15 char only") it redirects to new page and gives this message.......... if I use alert than incase or 2 or more validation fail it gives multiple or one by one alert boxes. I want to to displey my message near to field............... Code: function validateForm()
{
var x=document.forms["regform"]["email_id"].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;
}
}
Hello, I have a three field contact form on an HTML5 page. Using CSS3/HTML5 techniques, the fields change state as the info is entered properly (green OK symbol if good, red "!" if not, etc). That all works as expected in all browsers. My final hurdle is preventing the form being submitted with nothing entered in the fields. I have done hours of research and have tried several ways of writing the checkFeedbackForm function. My problem is that none of the solutions I've found are recognized by FireFox (mac and pc) and IE. They just ignore the javascript and allow the empty form to be emailed. Here is the code that is checking the fields: Code: <script type="text/javascript">
function checkFeedbackForm(form){
if(form.fullname.value=='') {
alert('Please enter your Name');
form.fullname.focus();
return false;
}
if(form.email.value=='') {
alert('Please enter a valid Email address');
form.email.focus();
return false;
}
if(form.message.value=='') {
alert('Please tell me a little bit about your ideas.');
form.message.focus();
return false;
}
return true;
}
</script>
Here is my form: Code: <form id="signup" action="mailinfo.php" method="post" onSubmit="return checkFeedbackForm(this);" > <input type="hidden" name="returnURL" value="thankyou.html" /> <fieldset><ol> <li><label for="fullname">Name</label> <input type="text" id="fullname" name="fullname" placeholder="Your name" required /></li> <li><label for="email">Email</label> <input type="email" id="email" name="email" placeholder="Your email" title="Please enter a valid email" required /></li> <li><label for="message">Message</label> <textarea id="message" name="message" cols="32" rows="8" placeholder="Your message" required /></textarea></li></ol> </fieldset> <input type="submit" value="Send It" /> <div class="privacy">Your information is for our project only and will not be shared or sold. Promise.</div> </form> Through experimentation, I have found that removing the ID from the form allows the javascript to function in all browsers, but that kills my form styling. I think it will be easier to fix the javascript than redo my CSS. This may be obvious, but I'm not a programmer. I'm a designer who muddles through on small scale stuff like this. Any help is greatly appreciated. Thanks. Hi. I'm trying to get my script below working. I've managed to get it to add fields dynamically but the remove function isn't right... and I can't think of a way round it. any ideas? also.. how can i incorporate a way for a limit on the number of fields that can be added? cheers! any help would be very appreciated. Code: <script type="text/javascript">
function addInput()
{
var x = document.getElementById("inputs");
x.innerHTML += "<input type=\"text\" />";
}
function removeInput()
{
var x = document.getElementById("inputs");
x.innerHTML -= "<input type=\"text\" />";
}
</script>
<input type="button" value="add field" onclick="addInput();" />
<input type="button" value="remove field" onclick="removeInput();" />
<div id="inputs"></div>
.. update: ah, i've just looked into the operators in more details and -= is just for numbers... so this won't work. i presume this is going to be the wrong method then. Hi, My code seems to work individually it is when I try to do multiple input validation that everything goes wrong. I have tried at the moment to cut it down to just two validation inputs to simplify things, but the more I try and play around with it the worse it seems to get. I know a lot of people post about this but I have tried comparing to other people's codes and solutions and just can't work out what is wrong. I would be incredibly grateful for any help. Code:

I have written a form in HTML which contains username,lastname,email,password and submit. I have written a javascript to validate this form [validate(username,lastname,email,password)]. On submit this javascript function will be called and hence form get validated. I am passing all the arguements(username,lastname,email and password) to the javascript function.. Is it possible to make me a code such that it should call an individual function for each field in the form.for ex:if i have not entered username, last name in the form and attempt to submit, only username arguement should be passed to the function as it comes first in the form. In other sense i want to validate individual text field validation of my form. So can anybody help me.It will be very needful to me.

Hey CF, I'm currently working on a website called 'eXtreme Gaming' I've almost completed it, apart from two things. - Adding two values on my checkout page for the Grandtotal (I've tried everything, but I'm too much of a noob and have probably missed something small). - Validation of forms (I don't know where to start here, I've looked on w3schools for tuts etc but I'm having difficulty incorporating it on my site) I'm going to put the code for my checkOut page only, if you are able to help me many thanks in advance.

/quote] I've set up a mock registration form page so I can learn a bit about javascript's form validation. (newbie) I want to try to attempt to style the border of a form field green when the user enters the correct info into the form text field and red on all other fields if the user doesnt enter any info into them. When i test it, enter the right info into the username field, leave the others blank, and hit the submit button it styles the username field green ok but it doesnt make the next fields (password and so on) red. Could someone please explain what I am doing wrong? here is my code so far... Note: just for testing purposes I've put return false on everything so it displays a message when everythings ok. Code: ....
<script type="text/javascript">
window.onload = function() {
document.forms[0].username.focus();
}
function validate(form)
{
var form = document.getElementById("reg");
var e = document.getElementById("error");
e.style.background = "red";
for(var i = 0; i < form.elements.length; i++)
{
var el = form.elements[i];
if(el.type == "text" || el.type == "password")
{
if(el.value == "")
{
e.innerHTML = "Please fill in all fields!";
el.style.border = "1px solid red";
el.focus();
return false;
} else {
el.style.border = "1px solid green";
return false;
}
}
}
var un = form.username;
un.value = un.value.replace(/^\s+|\s+$/g,"");
if((un.value.length < 3)|| (/[^a-z0-9\_]/gi.test(un.value)))
{
e.innerHTML = "Only letters,numbers and the underscore are allowed (no spaces) - 3-16 characters";
un.focus();
return false;
}
var pw = form.password;
pw.value = pw.value.replace(/^\s+|\s+$/g,"");
if((pw.value.length < 3) || (/[^a-z0-9]/gi.test(pw.value)))
{
e.innerHTML = "Only letters and numbers are allowed (no spaces) - 3-16 characters";
pw.focus();
return false;
}
e.innerHTML = "You filled in all the fields, well done!";
e.style.background = "green";
return false;
}

Hi guys, I am trying to re-work some pre-written Javascript code at which I am a novice at (I'm more CSS, HTML, PHP...). I am trying to validate a form field for a Purchaser's last name while accounting for an apostrophe if they have one in their last name. I bet it's something simple, but I still haven't been able to figure it out, or write it correctly: Code: function checkPurchaserName()
{
var err = false;
var f = $(getApogeeElement('purchaser_name_first'));
var l = $(getApogeeElement('purchaser_name_last'));
if ( f && l &&
( f.value.toLowerCase() != first.toLowerCase() ||
l.value.toLowerCase() != last.toLowerCase() ) )
{
error_list[error_list.length] = 'The name of the purchaser must match the applicant.';
errorHighlight(f);
err = true;
}
return err;
}
As an example. I started the purchasing process with the name "Patrick O'Malley". At the end page where this validation occurs, they have (2) text boxes, one for "first name" and one for "last name". They must type the same exact name for purchaser that they did for applicant, so "Patrick", then "O'Malley" Can someone please put me on the right track? Thanks. Hi, I have a working contact form with 3 of the fields requiring validation and they work well. I have added extra fields to the form (StatusClass, Project, CameFrom). These 3 fields return fine but I need to validated them. My problem is that the new fields don't show in the behaviours/validate panel even though they are within the form tag. Can anyone give me any help and advice as to how to accomplish this? Many thanks Code below.... Code: <script type="text/JavaScript">
<!--
function MM_findObj(n, d) { //v4.01
var p,i,x; if(!d) d=document; if((p=n.indexOf("?"))>0&&parent.frames.length) {

if(!(x=d[n])&&d.all) x=d.all[n]; for (i=0;!x&&i<d.forms.length;i++) x=d.forms[i][n];
for(i=0;!x&&d.layers&&i<d.layers.length;i++) x=MM_findObj(n,d.layers[i].document);
if(!x && d.getElementById) x=d.getElementById(n); return x;
}
function MM_validateForm() { //v4.0
var i,p,q,nm,test,num,min,max,errors='',args=MM_validateForm.arguments;
for (i=0; i<(args.length-2); i+=3) { test=args[i+2]; val=MM_findObj(args[i]);
if (val) { nm=val.name; if ((val=val.value)!="") {
if (test.indexOf('isEmail')!=-1) { p=val.indexOf('@');
if (p<1 || p==(val.length-1)) errors+='- '+nm+' must contain an e-mail address.\n';
} else if (test!='R') { num = parseFloat(val);
if (isNaN(val)) errors+='- '+nm+' must contain a number.\n';
if (test.indexOf('inRange') != -1) { p=test.indexOf(':');
min=test.substring(8,p); max=test.substring(p+1);
if (num<min || max<num) errors+='- '+nm+' must contain a number between '+min+' and '+max+'.\n';
} } } else if (test.charAt(0) == 'R') errors += '- '+nm+' is required.\n'; }

Okay so i followed a tutorial on how to create a wysiwyg rich text editor. The script has a function that makes it possible to take an image uploaded on an another site and use it. What i want though is to let the user upload an image directly into the text editor. Is there a way to do that in javascript? and if so, can you guys please help me write it, cause i can't find anything on the web about it... ? btw, is it possible to write a function that allows the user to show a video from youtube just by entering the url address? Code: <div id="content">
