The form submits even if no input is provided. The database get updated with blank values.
I have a DOM loaded from a remote site, i cannot alter that page. The DOM has a input:submit in the form that looks something like this:
<FORM NAME="frm1" METHOD="POST" ACTION="ServletController;jsessionid=72CDF83C126FFF9D87821CE9E9B9E860.fre01" onSubmit="return checkFormSubmit();">
<input type="hidden" name="mode" value="apply">
<input type="submit" name="Apply" value="Apply" onClick="return applyClicked();">
</FORM>
I need to replace the default ACTION with an ajax post with the current form data, but I also need to keep the:onClick="return applyClicked(); here is what works, however I cannot get the return applyClicked() to prevent the submit if it is false.

I want to say that if the email textbox is not empty, then do the Email validation, which does work on its own. It is part of a function.
View 6 Replies View RelatedI have a form with multiple fieldsets which are visible conditionally. There are three submit buttons "Abandon", "Save" and "Save & Continue". Each button should validate specific controls of the form and submit it. I tried setting "onsubmit: false" and checking for "$('#myForm').valid ()" on click of these buttons., but that validates all controls of the form.
View 1 Replies View RelatedI am using jquery autocomplete to retrieve values from database I need to implement empty item validation the point is that if there is no value in database user can insert it with bottom which appears somewhere in form. I try to usesearch: function () but can't figure out how to catch item length.
Code:
,search: function(event, ui) {
//Your ajax parameters...
//success: function(data) { //No idea what format your data is in...
// if(data['status'] == false) { //there is no result
//if ( ui.item == '')
//{
//alert(ui.item.value);
//}
if (ui.length < 2) {
// handle no data case specially
alert('test no date');

I have this form that validates a few textboxes & a dropdownlist. And when it is not filled in, the border of the textboxes and dropdownlist would turn red, followed by an alert message notifying which field have not been filled in.Else, the border will revert back to black, and the form will be submitted successfully. Right now, I would like to prevent the user from entering blanks (like entering a space to cheat the system). How should I tweak the codes to make it work?
View 1 Replies View RelatedI want to prevent submitting a form if any of the field is empty. also if possible I would like to validate some basic things. All I want to use JQuery: How do I do that?

I've read enough about email validation to know that the only real validation is having a user respond to a confirmation message you've sent them. However, I want to store the address temporarily, so I want to make sure what is entered is safe to work with.
I have a basic understanding of regexps, so I could write one that checks for a simple
format like: something followed by @ followed by something followed by
.. followed by something. I can also make a good guess at understanding
the regexps I come across in validation schemes people have posted.
However, each scheme that is posted seems to get criticized for
invalidating some esoteric, but valid, addresses.
I'm wondering if there is a minimum validation you can do that will
prevent basic attacks like sql injection attacks. For example, if I
weed out anything with single and double quotes, and semicolons, am I
barring some people unnecessarily? Seems like you'd be trying to mess
with people by putting a semicolon in your email address.
I'm using the Validation plugin for JQuery and was wondering if there was a function to submit the form without causing it to validate the form. I have a table with a list of radio-buttons and above that is a drop down list of states. The drop down list of states is used to filter the table rows and when the selected item changes it posts-back to the server (via $("#frm").submit()). I don't want this to cause any validation to occur. Is there another function I can call besides submit(), or some other method?
View 1 Replies View RelatedI am using the validate plugin with the defaultvalue plugin (empty fields given a default value and class of empty), and would like to use it together with the validator plugin. Is there a way to mark required fields with only the default value (and class empty) as invalid on submit?
E.g.: First_name field is required by validate, has a default value of "Enter your first name" and class of "empty" - how can I get the validator to mark this as invalid?
I've got a table where I'm trying to append additional input and file fields when someone clicks a link. The appending works fine, but when I click submit, none of the appended values are being passed through.If I hardcode a second set of inputs below the first, it works fine.
View 1 Replies View RelatedI have a general form validation question. I know very little about
javascript, a little more about PHP. Using yav (http://yav.sourceforge.net):
<form method="POST" name=edit onsubmit="return performCheck('edit', rules,
'classic');" action="pages_edit_submit.php">
<input type="text" name="title">
<input type="submit" name="Save">
<input type="submit" name="Cancel">
</form>
.... PerformCheck fires when any submit button is click, which is logical but
I'd like to prevent this if it was the cancel button that was clicked (and
preserve form submission on pressing Enter whilst in the 'title' box.
I am using an e-commerce solution to run my web business. The checkout portion of the website is COMPLETELY closed off to me and I can't access the files.What I need: A javascript example / solution that will prevent someone from submitting a form without first filling in a field.What I currently have is a series of radio buttons built into the checkout process. It displays 20 options and the customer has to choose which one of the twenty options applies to them. Each customer only has 2 valid options to choose from based on their zip code, but currently the other zip code shipping options are listed as wellI have built a javascript that works great hiding all of the shipping options, taking data from the customer, and then only showing the correct shipping option. The problem is, if the customer doesn't fill this out, then they can just hit submit and pay the default shipping option without ever seeing that they didn't choose the correct zip code

i am currently disabling the submit button but when the user clicks back(from the next page) it asks whether it should resend data. when the data is resent it loads the original version of the page(without submit disabled).
I need to validate two forms containing multiple input fields but want just one error message if any of the fields are left blank, the page is required to submit the users details (registration form). Also if any of these fields are left blank i don't want to be able to go to the next page on clicking the submit button

View 1 Replies View RelatedI am doing a password reset form using Jquery and PHP. If I try to submit an email id it should sent and email and report back the response text as success so that the user knows email has been sent.

I have a simple PHP form and to prevent double data submission, once the user has clicked 'submit', I want to disable the submit button using JavaScript. It was recommended in another thread that one could accomplish this using jQuery and the following code:
Code JavaScript:
$('input[type="submit"]').click( function() { $(this).attr('disabled','disabled'); } );
However, I also read that some browsers don't like having the submit button disabled, and that a more "elegant" way to do things would be:

When you press the down key while in an input field the default
behavior for some event creates a dropdown of the previously input
text. What event creates that behavior and how do I stop it ?
For example, to prevent ANY type of default behavior when clicking ANY
key, I thought this would work, but the dropdown still occurs. What am
I doing wrong ?
In html file:<body >

I'm currently developing an online work brief, where the user has to
enter details regarding the project into a form. I've come to a section
in the form where the user has the option of selecting between two
checkboxes and an input element. I have to ensure that at least one of
the checkboxes have been checked or that the input element is not
empty. I've come up with this function:
function validateMedia(){
var count = 0;
if(document.workBrief.mediaOnline.checked){
count++;
}
if(document.workBrief.mediaPrint.checked){
count++;
}
if(document.workBrief.mediaOther.value != ""){
count++;
}
if(count 0){
return true;
}else{
alert('Please choose at least one media option');
return false;
}}
I'm sure there is a more effiecient way of writing this.
