i have a form being filled. i don't want the user to be able to submit twice. how can i either prevent the user from going back or disable the submit button?
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).
How can I make this code disable the submit button once it has been pressed, then if the user hits back or GOES back, it will re-enable it again?

I'm looking to have a lightbox pop up when a user clicks the Back button in their browser rather than just navigating back. The purpose is to ask a question with a Yes/No answer, and if they click No, I allow them to go back. The only thing I've found anything like this is the onUnload event, but that doesn't prevent them from going back. How should this be handled?
View 1 Replies View RelatedI 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.

What is the command to prevent "right clicking".
View 12 Replies View RelatedI run a website and we have an ad agency who despite our repeated requests, does not filter run of network ads to make sure no popups are served or ads with sound are run. However, we can't afford to drop them and no other agency is going to give us the fill rate/CPM we are currently getting. So we need to take matters into our own hands, and I hope it's possible. We need to put a script on our site which overrides any javascript/flash served via ads and prevents popup windows from opening (or auto-closes them). We also need a way to disable sound within the current tab. Is that possible at all?
View 1 Replies View RelatedI've gotten .load to load content into a div but if the window is not at the top of the page it scrolls back to the top each time the new content is loaded but I wanted to avoid any sort of change on the page other than the content in the div. It seems pointless if the user has to scroll back down to the div where the content is each time? code...
Is there a way to keep the window in the same position? Also while I'm at it - is there a more efficient way to write this considering I have 9 pages or should I just write this code out for each instance?
I have a page with many forms that I need to change from a post to an ajax call. That part is working, no problem, but now I want to disable the submit button while it's waiting on the server response and then re-enable it when the response comes back.
Here's what I have:
$(function() {
$('form').each(function() {
$(this).submit(function(){
[code]...
I can't figure out what my selector should be to get the submit button of the form that's being submitted. What should I be using instead? Also, if the call errors out, I'd like to just post the form as usual.
I have a form without a submit button. It gets submitted programmatically with document.form.submit().
What I need is to be able to disable this form's submit capability on page load and then reenable it at some later point. Remember there is no 'input' button element.
Code:
What I've tried so far is like this:
savedSubmit = document.inputs.submit;
document.inputs.submit = None;
then later:
document.inputs.submit = savedSubmit;
but this does not work. How can I do this?
I'm desinging a graphical interface and I frequently take advantage of the double click event. Unfortunately in most browsers double clicking also involves selecting and I would like to avoid that since whatever is selected has dark blue background and white letters what spoils the whole visual effect.... Any way I can block it por avoid it?
View 3 Replies View RelatedI own a game site and some users cheat by changing the browser URL. For example :
The URL for starting a game mission is this : ww.somesite.com/somethingaspx?htxm=18
And if they change the number to 87 they go to the end of he mission WITHOUT actually completing it.
They ONLY way to deal with this is by preventing users from changing the URL manually. Is there a way to do it? Like, if someone tries to change that number in the URL he gets a message and browser window closed(or something that will prevent him from going to that page)
Of course, the solution must not conflict with the normal navigation(which is the actual mission) which means the user should be able to navigate to different pages but NOT change the URL manually.
I wish for my users to retype their email address instead of the copy and paste method to ensure they have typed it correctly both times.
How could this be done, would it be Javascript ?
<script type = "text/javascript">
function testfield() {
var un = document.getElementById("dir").value;
if (!/^(/ftp/nas)/i.test(un)) {
alert ("Invalid starting characters - must be /ftp/nas");
return false;
[Code]...
I have a code like above which doesn't allow the user to proceed with out starting the field with a "/ftp/nas" which should be the starting of a path. Is there any way to make it disabled and the user only can enter the rest of the path. for eg: user1 has directory path like /ftp/nas/user1/help
so when this user enters his path, on the field "/ftp/nas" should always be available and the user has to only enter the rest of the path. and the user is allowed to enter only / (// is not allowed) and [A-Za-z] in the field. this is just to secure the application from typing mistakes.
Is there js to prevent malicious clickers who try to ban my site from google ads by clicking so many times?

I would like to disable the back button in IE7 and IE8. I assume the best way is to use window.open. I tried below and it disabled the IE back button but doesnt show the menu items, url bar etc.

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

View 9 Replies View Relatedis there a way to prevent user from adding more characters into a text input based on a validation rule(eg. you entered more than n words, you can't enter more, but you can delete or edit)? I think I'll have to programmatically delete the extra letter(s) that user just input somehow if the addition causes a violation of the rule, is this the best way?

I have a form with some text fields that are disabled UNLESS a checkbox is checked. Initially the text fields are disabled and the checkbox is unchecked.
The code is something like this:
Code:
function disableTextbox() {
if (chk.checked) {
txt.disabled = false;
} else {
txt.disabled = true;
}
}
<form action=something.cfm>
<input type=checkbox name=chk onclick=disableTextbox();>
<input type=text name=txt disabled>
<input type=submit>
</form>
When the form is submitted, some validation is performed. If anything fails, I display an error message and show a link to go back (history.back).
The problem that I am having is that when you click on the link to go back, the checkbox on the form is checked, but the text fields are disabled.
You have to re-click the checkbox to update the text field.
I want to disable all the option, which inlcude:
using right click and select back,
pressing the backspace button on keyborad
and the back option on above menu to be disabled.
and other ways of going back to previous page.
Is there a way to do that using JS.
I'm trying to set a cookie when a user clicks a hyper link.
Do you think I should prevent the default behavior of pressing a link first, and then set the cookie?
Or could I just set the cookie on a hyper link click event, and hope the client sets the cookie, before they are directed to another page.
