JavaScript - Onblur Event Creating Problems With Form Validation
Hi everyone,
The following code has an onblur event in the input fields so that if someone clicks out of the field without typing something in it, the original label, ie. 'First name' is reinserted into the field. The field is also being validated by some php code, however the onblur event creates a problem because the form still submits even if a name isn't typed into the field. It's assuming that 'First name' is an entry and therefore isn't validating it correctly. It was suggested that on the submit event of the form, there would be a function that checks if the value is First Name then return false, but then otherwise return true. As my javascript skills are very basic, I wondered if someone could help me with this code to solve this issue? Appreciate any help. Code: <input id="firstname" name="firstname" type="text" value="First name" onfocus="if (this.value == 'First name') this.value=''" onblur="if (this.value == '') this.value='First name'" />
<?php
if (ValidatedField('index_965','index_965')) {
if ((strpos((",".ValidatedField("index_965","index_965").","), "," . "1" . ",") !== false || "1" == "")) {
if (!(false)) {
?>
<span style="color: red"> First name is required </span>
<?php //WAFV_Conditional index.php index_965(1:)
}
}
}?>
Similar TutorialsI have an onfocus event that makes a textarea large and then an onblur event that sets it back to a smaller textarea. If I click the textarea the onfocus event is triggered but if I go straight to submit the form the onblur event is triggered and the form is not submitted unless i hit submit twice. How can i get the form to submit? Can i put an "if" statement in the onblur event to see if the form is being submitted then just submit the form otherwise run the onblur event? Code: <style type="text/css">

Realizing that form input placeholders aren't universally recognized among browsers, I began changing all of mine using onblur and onfocus handlers instead. As an example, I used the following code, which works in most cases: Code: <input type="text" name="example" maxlength="5" value="Example" onblur="if(this.value=='') this.value='Example';" onfocus="if(this.value=='Example') this.value='';"/> At first, I coded all of the inputs without a value attribute. But, when the page initially loaded, the fields would load empty, and the value/placeholder wouldn't appear until the field had been "focused" and then "blurred" again. Adding the value attribute seemed to correct that problem, again, for the most part. I have some text fields that appear only after I select a particular radio button or select option. Problem is, when the radio is clicked, the field appears, but even with the value attribute in place, the field appears void. I'm not sure what is different, or what I'm doing wrong. Here's the javascript code with the radio button (note:everything works except that the "placeholder" doesn't show when the field first appears): Code: function showfield() {
document.forms[0].otherRelation.value = "";
document.getElementById("newBox").style.display = "none";
var r = document.forms[0].relation;
var len = r.length;
for (var i =0; i<len; i++) {
if (r[i].checked && r[i].value == "Otherrelation" ) {
document.getElementById("newBox").style.display = "inline";
}
}
}
<input type="radio" name="relation" value="Otherrelation" onclick="showfield()"/>Other
<span id = "newBox" style="display:none">:
<input type = "text" name="otherRelation" size="35" value="Your Relationship" onblur="if(this.value=='') this.value='Your Relationship';" onfocus="if(this.value=='Your Relationship') this.value='';"/>
</span>
Thanks for any help. Sorry so long. Hi, I have a problem in javascript, where entering a value in the textbox during onblur I am doing a refresh to bring in the updated records from the DB , before the on blur refresh is completed if the user clicks the search button (onclick) during the first click nothing is happening as the refresh is still going on. During the second click when the on blur refresh is completed it will open a popup. The problem here is I am unable to disable/inactivate the search button untill the refresh is completed as well as I dont have any control over the refresh time as well. This is like already an event is in progress and where we are invoking another event which is not having any effect. In such case how i can handle this scenario? Thanks. Hello all, As this is an active javascript programming forum...i'm really hoping i'll get a solution for my problem...please help me out.... I have a html: text inside a logic:iterate block like this.. <logic:iterate name="AllocationsForm" property="newSearchAllocations" id="allocations" indexId="myindex" > <html:text name="allocations" property="newStartDate" indexed="true" onblur="allocationTest(this, " + myindex + ");" /> </logic:iterate> i want to write a onblur event for this text field inorder to validate it. Is it the correct way i wrote or something i need to make a change in the above code inorder for the javascript to work. Can we really able to write a onblur event for a indexed text field that is inside a logic:iterate block. please let me know. Thanks in advance. Hi everyone. New programmer here trying to get fix this one specific issue I am having and I could use some help. Using Javascript, ASP.net with C# code behind. I am validating a textbox using the onblur event. It is being validated in that it must have an alphanumeric entry before the user tabs off of it to the next box. The validation part works, the part that doesn't work is that I get the validation alert textbox if I close the window. I have a workaround in that I am assigning that textbox a character using windo.onberforeunload but I know that isn't right. Here is what I have so far... Code behind on Page_Load... Code: txtCLBRTNWC.Attributes.Add("onblur", "return reqVLD(this)");
here is my textbox field... Code: <asp:TextBox ID="txtCLBRTNWC" runat="server" Width="75" MaxLength="4"
ontextchanged="txtCLBRTNWC_TextChanged" TabIndex="1"
onkeyup="clbwclngCHK(this);" ></asp:TextBox>
And here are the 2 functions being used... Code: function reqVLD(alphanumericChar)
{
var chk = /^[a-zA-Z0-9]+$/;
// var boxid = document.getElementById("<%=txtCLBRTNWC.ClientID%>").value;
// var matchArray = boxid.match(chk);
if(document.getElementById("<%=txtCLBRTNWC.ClientID%>").value.match(chk))
{
return true;
}
else
{
document.getElementById("<%=txtCLBRTNWC.ClientID%>").focus();
document.getElementById("<%=txtCLBRTNWC.ClientID%>").value = "";
alert("Please enter a Work Center.");
return false;
}
}
function clbwclngCHK(obj_in)//When txtCLBRTNWC entry hits the max of 4 auto focuses to next box.
{
if (obj_in.value.length == 4) document.getElementById("<%=txtSTRTDT.ClientID%>").focus();
}
Here is my work around... Code: window.onbeforeunload = function ()
{
document.getElementById("<%=txtCLBRTNWC.ClientID%>").value = "1";
}
Summary. User has to enter something in box before they can move on. This is checked and validating using an onblur event. Problem is, the onblur event fires if closing\exiting the window. I know there has to be a better way of doing this. Any advise or help would be greatly appreciated. Thanks Will Hi, I'm trying to automatically generate a new <option> tag in a html form using the below code, but it's not working. Does anyone have any ideas? The get_lightboxes function is being called via the add_to_lightbox functon. Javascript: function get_lightboxes(title, new_lightbox_id){ var new_option = document.createElement('option'); new_option.text = title; new_option.value = new_lightbox_id; var select_box = document.getElementByID('lightbox_select'); try { select_box.add(new_option, null); } catch(ex) { select_box.add(new_option); } } HTML: <form method="post" action="<?=$_SERVER['PHP_SELF']?>" name="lightbox_form" onsubmit="add_to_lightbox('<?=$_GET['id']?>', '<?=$_GET['media_urn']?>', lightbox_select_<?=$_GET['id']?>.value); return false;"> <input type="hidden" name="submitted" value="1" /> <input type="hidden" name="user_email_<?=$_GET['id']?>" value="<?=$_GET['user_email']?>" /> <input type="hidden" name="record_id_<?=$_GET['id']?>" value="<?=$_GET['id']?>" /> <input type="hidden" name="media_urn_<?=$_GET['id']?>" value="<?=$_GET['media_urn']?>" /> <h2>Add/Delete from existing lightbox:</h2> <p> <select name="lightbox_select_<?=$_GET['id']?>" id="lightbox_select"> <? foreach ($get_lightboxes as $lightbox) : ?> <? $lightbox_id = $lightbox["lightbox_id"]; ?> <? $title = $lightbox["title"]; ?> <? if(strlen($title) > 25) $title = substr($title, 0, 25) . "…"; ?> <option value="<?=$lightbox_id?>"><?=$title?></option> <? endforeach; ?> </select> <input type="submit" name="submit" value="Add" /> </p> </form> 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.

super thanks!!!!!! -pumpkin Hi guys, Probably a simple fix, the below code is for a form that is validated against some external (valid.js) functions. It's my first forray into Event Delegation and stupidly (testing in FF only just now) I didn't realise that the addEventListener isn't recognised in IE. Anyone got an idea which way I should look at sorting it. I am still searching and playing around but can't seem to find the right solution. Thanks in advance Code: document.addEventListener('keyup',function(event){
//IE doesn't pass in the event object
var event = event || window.event;
//IE uses srcElement as the target
var target = event.target || event.srcElement;
var strId = target.id
switch(target.id){
case "M_FIRSTNAME":
validEmpty(strId,"* Please enter your 'First Name'.");
validChars(strId,Letters,"* Your 'First Name' contains invalid characters.");
break;
case "M_LASTNAME":
validEmpty(strId,"* Please enter your 'Last Name'.");
validChars(strId,Letters,"* Your 'Last Name' contains invalid characters.");

I have a parent div, that when hovered over changes the background color. There is a onclick event so that a user can click anywhere within the div for the link to work. Inside that div I have another div with unique links. When I click on any of those links, it also activates the other onclick event. I don't want this. :-/ Here is my code Code: <div class="cat1" onmouseover="style.backgroundColor='#09F'; this.style.cursor='pointer';" onmouseout="style.backgroundColor='';" OnMouseUp="location.href='http://a.com/details.php?id=305366';"> <div class="itemwrapper"> <div class="datebox">Wednesday - January 3rd, 2007</div> <div class="timebox">08:00am - 08:30am</div> <div class="subbox">Blah</div> <div class="peoplebox"><a href="mailto:a@aol.com">George</a></div></div> </div> I'm guessing I need to create some type of function that will detect where the click came from and then decide whether to fire it or not? Thank you in advance for your help. Hello all, new here Seems like a very nice place to be apart of. I have my website www.gebcn.com. If you view source you will see all that I have done, but more importantly my problem. I have the JS code at the top there and I am unable to W3C validate my HTML because of the JS. I am using XHTML strict and would like to stay using it. The JS I have at the top is my form validation code. I am able to do any validating that I need with this "snippet" of code, I have shrank it from my library version just to use for this newsletter. Until now W3C validating was not important now for some reason it is and I am faced with this problem. I am not a Javascript guy more of a HTML/CSS guy and I can manipulate JS to suit my needs. <problem> I have tried to make this "snippet" of JS code an external file but receive multiple errors with the JS calling for the FORM NAME as it is not on the same page. The form NAME=NEWSLETTER is another problem, as W3C says I am unable to use attribute "NAME" in this location. <problem> I would like to keep the JS close to how it is now as I have a library to use this JS over and over again. Any pointers in the right direction or solutions to my problem would be greatly appreciated. Thanks! Hopefully it is not to hard huh If there is anything anyone needs, the code pasted here, or anything else please let me know. Thanks again! Hey guys, im a bit of a loser with Javascript and need a bit of validation done but I have no idea what the problem is with my code, can anyone help? Form: Code: <div id="Layer3">

Im sure there are a few syntax errors but any and all help is greatly appreciated I'm having trouble figuring out this code. I have a isInitialsTextValid function that checks to see if the user enters their initials in the correct format. Then I have a function checkInitials. In the checkInitials function I am supposed (1)to declare a variable to be used for the boolean value returned by the isInitialsTextValid function.(2)call the isInitialsTextValid function.(3)If the value returned is false, place focus back on initials textbox.(4)If the value return is true call the submit function. I'm not sure what I am doing wrong, but I get a checkInitials is no defined error from firefox and it is pointing to my xhtml file. Here is the relevant code.

Hey Everyone, I would like to let a select menu drop down with the click of a button or image. So, I have: Code: <select> <option>Option1</option> <option>Option2</option> <option>Option3</option> <option>Option4</option> </select> So, how do I trigger this select menu to drop down, except for clicking on the down arrow? Thanx in forward Hello ladies and gentlemen, I would like to use some event handling on a form, not something I have done before and looking for some assistance. Here is my code: Code: <select name="LocO"> <option value=""></option> <option value="O">Outside</option> <option value="I">Inside</option> </select> <select name="LocA"> <option value=""></option> <option value="A">A</option> <option value="B">B</option> <option value="C">C</option> <option value="D">D</option> <option value="E">E</option> <option value="F">F</option> <option value="G">G</option> <option value="H">H</option> <option value="I">I</option> <option value="J">J</option> <option value="K">K</option> </select> <select name="Loc1"> <option value=""></option> <option value="1">1</option> <option value="2">2</option> <option value="3">3</option> <option value="4">4</option> <option value="5">5</option> </select> So what I need to happen, is based on the selection of the first selection box, some of the options of the other selection boxes should not be available. If Outside is selected, everything in LocA should be available, but only up to 4 in Loc1... and if Inside is selected, only up to E should be available in LocA and everything should be available in Loc1. Is this possible? I've literally tried everything. Read 26 tutorials, interchanged code, etc. My validation functions all work. My AJAX functions work (tested manually using servlet URL's). The second servlet validates the reCaptcha form that's generated on my webpage. After the form is validated, even if everything's correct, nothing happens upon clicking submit. I even have an alert pop up if with the captcha result, just for middle-layer debugging purposes. I want to do all of my validation clientside; none serverside. However, going to be tough if I can't get my god damn form to submit. I've been puzzled by this for close to 36 hours straight. I can't see, and I'm going to get some rest and hope that there is some useful insight on my problem when I return. html form: Code: <form id="f1" name="form1" onsubmit="validate_form(this); return false;" action="register" method="post">

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++)

Hello all, I have a multistep jquery form that validates user input and then should send me an email. Problem is, right now, I can only get it to validate the first page, then it sends the email before the rest of the pages are viewed. I'm just trying to delay the submission of the form until the "submit_fourth" button is pressed. I've got $25 via paypal for the one who sticks with this one for long enough to come up with a workable solution. Here is my code... I know it's a lot, but I wasn't sure how much would be helpful. HTML code is in the second post in this thread (it was just too much to fit in one go). Cheers! -Dave The Javascript: Code: $(function validateForm(){
//original field values
var field_values = {
//id : value
'name' : 'your name',
'email' : 'email',
'phone' : '(555) 123-4567',
'other' : 'other',
'detail' : 'project overview'
};
//inputfocus
$('input#name').inputfocus({ value: field_values['name'] });
$('input#email').inputfocus({ value: field_values['email'] });
$('input#phone').inputfocus({ value: field_values['phone'] });
$('input#other').inputfocus({ value: field_values['other'] });
$('input#detail').inputfocus({ value: field_values['detail'] });

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">

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;
}
