Disallow Typing Of Few Of Characters E.g.'<', '>' In All Input Textboxes Using Jquery?
Jun 16, 2010
How do I achieve this:-When user types character like 'abcd' and then '>'(an invalid character for my application), I want to set the text back to 'abcd'. Better if we can cancel the input itself as we do in winforms application. This should happen when user is typing and not on a click of button.I want this to be applied on all text boxes in my web page. This will be easy if the solution is jQuery based. May be something which will start like this.$("input[type='text']")SOLUTIONI used both of the answer provided by @jAndy and @Iacopo (Sorry, couldn't mark as answer to both) as below.
$(document).ready(function() {
//makes sure that user cannot enter < or > sign in text boxes.
$("input:text").keyup(purgeInvalidChars)
My testers have discovered that if you type free text into a file upload input then none of the buttons on the page work until that text is removed (so the page cannot be submitted).
I am able to replicate this with the following ASPX code (with no code behind):
(Note that I haven't bound any handlers to the page; despite this, the page is submitted when the submit button is clicked only if no text is entered into the upload text box)
Is there any way to prevent users from typing free text into a file upload control? It seems that this is only possible in IE - Firefox and Chrome natively prevent text from being entered into upload input fields.
I've seen solutions elsewhere which suggest hiding input and replacing it with a label / button combo, but this seems like it might cause more problems and work inconsistently across browsers.
I wrote a chat client 1-1 but I need a way to be able to detect if the user is typing and display "UserA is typing message..." just like MSN messenger or yahoo messenger.. how can I detect that?
I am using a textbox to capture user entry to create a custom SQL select statement. I have everything working fine but while I was testing, I noticed something...
Suppose I wanted to search by last name and I entered, "O'Dooles" in the textbox. I would get an exception thrown at me since the apostrophe is used for SQL syntax. I got around that by using the Text.Replace method to swap the single apostrophe for a double one. That got me to thinking.
Are there any other characters I would need to watch for that could throw exceptions?
I'm also guessing there is a much better way to handle all of this. I have seen some of the security issues involved with this. I haven't done much looking into it but is using parameterized queries an option?
I would like to transform an html input to xml. But the input will have as part of its content an "&", e.g. Texas A&M. But calling XslCompliledTransform.Transform(htmldocument, xmlwriter) causes an xmlexception to be thrown.
But I don't think all IE versions of 6 and greater support this.
I think I'd like to avoid skins. Not sure why, other than I tried them and I recall having a negative experience. It was probably my lack of knowledge. Are there any issues in using and CSS, external or otherwise?
What's the best way to handle this? Currently I am assigning separate classes to each control type.
Only the first input character was automatically converted to uppercase. The rest inputs are not converted. Do you know what changes I need to make it work?
I am upgrading part of a very old website. One of the pages that I own uses controls and dlls that I do not. There is one dll that puts a textbox (input field) on the page. This field is concepually a label but the person chose to use a textbox. Anyways, I can't change the dll.
Is there a way in my asp.net page that uses the dll to say all the textboxes on this page should have a transparent background?
This is the code I have access to. Any changes I make have to be made here.
I've written a small class .That has a method for adding and subtracting.
My class file is fine and everything works well when I hard code the integer values. But the moment I try to use textboxes in my methods signature to accept values it complains that this is an inavlid argument. I assume that this is because I used int as my signatures but then how can i use my class to textboxes as input.
I am having difficulty with getting the values from two textboxes to passed the values to one function and determine that one textbox cannot be greater than the other textbox, then i can issue alert message.
i have my own DLL (for the data access layer),,i use escaping characters technique to avoid the user input errors ,, but recently i decided to enhance my classes and using parametrized query to prevent all possible errors,Is the modification will be easy or difficult ??how to convert this way to use the parametrized query ..
I could also write every validation for each object separately, I have only a few elements who uses a required validation but it would be nice that I could do this in one shot instead of repeating the $("input").rules("add .....
I'm looking for a regex that will allow Alpha Numeric and most all special characters except white space. It should be usable in c#. It would be nice if .net supported posix style but I can't seem to get it to work.
What is the best way to disallow editing of existing entries in ASP.NET Dynamic Data while it should still be possible to add new entries? If possible, I would prefer a solution without custom templates.
Here is my dilema, on my site i have a WordPress Audio player (http://wpaudioplayer.com/standalone) that plays my mp3's.
It loads the Mp3's in by javascript...example below:
AudioPlayer.embed("audioplayer_7", { soundFile: "/Files/Music/[name of file].mp3" });
This file name is clearly visible in the browser source. Not a problem, however this means that any user can legitimately browse to the file directly and download it.
Now i still need the mp3 player (which is flash) to have access to the file but if a user was to try accessing the file directly, they would not be allowed access to it.
I am not sure how to go about this, i am circling the idea of a httphandler but not sure if this is sufficiant to stop the direct access to the file.
I'm using CurvyCorners for making control's and other HTML element's corners curve in IE. But unfortunately they are not curvy the corners of buttons, textboxes and images.
So, I want to know how CurvyCorners on Asp.Net buttons and textboxes in IE? Is there any way through which we can curve the corners of buttons and textbox controls, using CurvyCorners in Internet Explorer?
i am working on asp.net, for example in a form they are 10 text boxes i want to validate each textbox if it is empty it should display a alert message.
how to achieve this by using a single javasript method. can we pass texbox as an argument into javascript how to achieve this
I have been looking for the best way to obtain the total number images in a folder where the first two characters on the file name are XX and place this number into a variable.So for example - I have a folder containing the following images:
XX-01.jpg XX-02.jpg XX-03.jpg YY-01.jpg ZZ-01.jpg
So I would populate the variable with 3 in this case.Does anyone know of any way to do this?
