Is there some javascript code I can put on my webpages to prevent visitors at my website from saving a web page to their hard drive, or printing a webpage?
Is there even a way to disable all the menus of their browser?
Is it possible to disable the browser from refreshing when settings document.location.href
for example here's what i would like to do
if you're at mysite.com you'll click on a link. that link will fire a func that will make the location mysite.com/about however i don't want the browser to refresh. instead i want to write some javascript that will do someother stuff. i know it seems pointless but for the project i am working on it actually make pretty good sense (to me at least LOL).
i don't care about clicking the refresh button or F5 right now. just not having the browser refresh when i change the document.location.
I have a quiz application made in PHP. The quizzes have a time limit, and i display the time left using javascript in a textfield. I always initialize the timer on document load. I also have a page navigation that switch between pages, and i maintain the time value from the last page.
Now the problem is that if the user clicks on back button of the browser and after on forward, the timer gets reinitialized with the start time, and in this way he can cheat. Can you please tell me how can i disable all navigation on my page?
I am trying to make a form where the user is only able to select an option from one of the drop down menus and if they click both then submit an error should pop up telling them to select just one. Now I have found this code:
<SCRIPT LANGUAGE="JavaScript"'> <!-- function validateForm(){[code]....
the first problem is that my menu must be named "id[2]2" which causes a problem due to the bracketed 2 and the 2 after. Is there any way around that?the second problem I forsee is that this will only work with 1 drop down box being unselected. I need a code that will give the warning if nothing is selected OR if something is selected in both drop downs.
I am writing a prgram in php.when i click "log out "button ,it redirects to my first page "index.php".(username & password)and then by clicking back button in the browser ,it showing all my previous pages that i visited.I want to disable back button in the browser (javascript should support in all browser) using javascript or php
can i add some simple function at the 'X' button (close button) on the browser which will check whether user enter all fields and if not, prompt them to enter.
(i wanna do this so user cant close the window in half way of the form process)
or is there anyway to disable it? or open a window without the title bar?
I've been tasked with the javascript and layout for an application that uses the browser engine (embedded browser I supposed it is). So it's not the actual browser, it looks like an application. Problem is, you know how you can drag and drop an image or html file into a browser and it will open it? Well, can this be prevented via javascript?
I would like to disable the ability of the user hold control and click and get the dropdown menu. I am ultimately discouraging users from easily getting a copy of the image. I was able to do this and disable dragging on all browsers I have tested except Safari (Mac). Code:
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 got this problem while disabling Up/Down arrow keys in Mozilla firefox browser useing javascript Given a standard HTML select/option box, I can capture any keypress while the select has focus and stop the select�s option list from changing values in IE but not in Mozilla.
[Code]....
In IE and Mozilla I have no trouble capturing the keyCode, and in IE I can prevent pressing a letter "D" and Up/Down arrows from making the list move to Dead, but the select list will drop to �Dead� in Mozilla. I've tried attaching the event handler to keyup, keydown and keypress, but have yet to find a way in Mozila to capture the keypress and prevent the select list from changing the current selection.
I am trying to make a webpage where I wish to disable text selection on entire body without affecting text input in a form by user. Though I found a couple of javascripts on the net, they don't seem to work with all three browsers (IE, FF, Opera). Code:
I have only started to learn HTML, CSS, and Javascript (roughly 2 weeks now). I am having a issues regarding when I submit form data to the server. I want to temporarily disable the 'submit' button while the browser is loading and then reactivate it once everything has finished loading. This was my attempt at doing this.
I've got a textarea form element being used for data entry, and I noticed in my testing that the "esc" key completely wipes out all the data when pressed.
Is there a way to either disable the "esc" key while in this screen, or is there another solution?
The following code is working fine in firefox n not working in IE8... I get the Object Expected Error when the code hits the if(GBrowserIsCompatible())..... line in the javascript code. Clear cache and browser history does not work. Does anyone have a resolution for this?
Is there a way in Javascript, or perhaps in HTML, to force a browser to re-render an image on an HTML page after a round-trip between the client and the server ?
In my particular case, the image is changing on the server although the URL for it remains the same, but the browser is still displaying the old image from its cache rather than the new image from its URL location.
I want to use jquery to detect what type of browser you are using and display a link to a .wmv file if you are on IE or display a link to a .mp4 file if you are any other type of browser.I have this script declaration in my <head> section.
On my site i use a lot of features that are unsupported by older browsers, and right now it looks pretty stupid when the features are only partially shown. So i was wondering if there's a way of making the browser look to different css files depending on which browser and version it is. For example, css3 gradient backgrounds are supported in firefox 3.6 or something, but not in 3.0. All the hacks out there is to 3.*, so it changes for the allready working 3.6 too if i hack it. I want to controll it so that i have a specific css file for the none-supporting version and lower and one for the supporting and above. I looked at a bad browser plugin (because it has some of the basic features im looking for)
I'm trying my hand at developing a new website for my professional career, and am trying to implement a simple Rollover > Pop-out Menu system, and am finding the javascript confusing to do. I am using Photoshop and Dreamweaver/Fireworks, and have all of my normal and over button graphics finished, and created one simple pop-out in Fireworks.
My problem is getting both the swap image in javascript onMouseOver event, and the menu event to run at the same time. How is this usually done? Can you add two functions to one java event?
