string jSFile = ResolveUrl("~/MyProject/JavaScripts/dir/test.js");
if (!System.IO.File.Exists(jSFile))
{
...
}
This code doesn't work and I guess it's the jSFile that doesn't work well with the IO.File.Exists but I know the jSFile has a valid path because when I use few line later
Page.ClientScript.RegisterClientScriptInclude("myfile",jSFile);
it does attach the JavaScript file to the ASPX and all work fine.
I am developing a web application for online bidding wher I want the BID button to disable itself, on all clients, whenever someone places a bid. What I need is some javascript to ping the site to check if a bid has been placed on the server, if so, then disable the button. I was suggested to use jQuery for this, use .ajax to query the server for the check. Then use a setTimeout javascript function to keep checking.I am not javascript expert at all so any tips would be greatly appreciated. At lease where to start. Also, will I need to record every single bid in database to achieve above?

View 3 RepliesI have requiremet like in checkboxlist displaying all country names from database. The first item is 'All Countries' and country names will start from second item. So, when user click on All All Countries checkbox, all the remaing items should be uncheck and when user click on of the country checkbox then 'All Countries' should be uncheck like that. I googled sometime but got the articles which are explaning with a separate checkbox for check/uncheck items in checkboxlist. I don't want a separate checkbox......the All Countries checkbox should be first item of the checkboxlist.

View 1 RepliesIm replying to this post (a few years back now) but your method was one I wanted to use for checking JS on page load.
I uderstand the value of testBox will be changed to yes if JS fires, and codebehind recieves the testBox value of yes.
Ive tried your exmple but its not working like this, what I get is the hidden testBox value NO passed when JS is enabled.

How to validate check box/ check box list in Model?
View 1 RepliesThe reason i need to do this is because of Facebook Connect - which is another story, so i'll save you the drama for that. =) Anyway, i have this function that runs on window.onload:
function userAuth() {
SomeFunctionWhichGetsFacebookCookes();
if (!loggedInUsingFormsAuth && loggedInViaFacebook) {
window.location.reload(); // refresh page, so i can perform auto-login
}
}
So, i need help in getting the flag "loggedInUsingFormsAuth". I dont care what is in the cookie, just need to know if the current user is authenticated. Why am i doing this? Well, on window load, if the user is logged into Facebook but not on my website (according to the Forms Authentication cookie), i want to reload the page - which allows my ASP.NET website to read the Facebook cookies in the HttpContext and log the user in. I need to do this in JavaScript, because i dont have the Facebook cookies until i call "SomeFunctionWhichGetsFacebookCookies" - which can only be done in JavaScript.
So, how can i work out if the current user is authenticated via JavaScript? Do i have to manually traverse through the cookies, find the one i want, and inspect it? Is this a safe thing to do? Or should i alternatively write out the flag to the client from the server using RegisterClientScript?

Suppose I have a master page where I have written some javascript to access the value of a particular asp.net text box, which resides in one of its content pages, but not in all the pages. This piece of javascript code can't be moved to that particular content page because of some restrictions.
Now I need a way to determine whether or not that text box exists in the page, which will imply that the content page containing that text box has been loaded.
How I can I do that in javascript?
