Alerting User To Invalid Data In Form Field Through Inline Alerts
Oct 3, 2009
I'm a little curious with regards to alerting a user to invalid data in a form field through inline alerts, rather than alert boxes and without a page load.In otherwords, if someone types in invalid data into a form field, before they hit the submit button, I'd like to use javascript the insert some red text on the side saying "this is invalid".I'm concerned that people with visual disabilities wont notice it due to their screen readers.I.e. if the screen doesn't re-load, will the screen read read the nexly inserted text or will it not do anything until a new page loads?
I am trying to validate a web form. Someone else wrote the Html code and implemented it with an iframe using asp and php. I didn't want to mess too much with the code so I decided to use javascript to make the form validate, before it was sending email alerts with every field blank. For the most part the validation works but it skips the email field for some reasons and is really bugging me to death. this is the code:
The following form validation script works, currently if one of the five fields are completed, a message appears the remaining field(s) must be completed etc. Although the information the user has inputted in the first field is cleared. How can this information be available, if there is one problem in the form it doesn't make sense that the user must re-input all the information again. I look forward to hearing your response,
i am creating a simple form validation script where i will ask for the username, password and email of a user. when an error is created, a text will be displayed beside the textbox. but i want to know how i can add colors to the textbox if there is an error.
The thickbox opens with the title "Preview", but is empty.I've alerted the div after setting it, and it does contain the formfield value.Why might this be happening? I've also tried setting the div like this (foo as dummy text - to no avail):
I would like to use jQuery to prepopulate a form - ie make a call to a php program to get data from a database and pre-populatea form with appropriate data for the user. Can anyone point me in the right direction for some examples on the simplest way to do this?
I need to pass user input from a form to one database field. I'm relatively new to JS but the idea I had was to have several form elements and use JS to collect the users input and send all the values through a hidden element. What's happening is the variable names are being sent rather than the values. The code below is only passing to the next page. Limitations: I am editing an intranet site built by a 3rd party so a lot of the files we've been given are encrypted. I cannot change the method to post.
I have PHP form application used to by Sales reps to Enter information about customers but I want to prevent Sales reps from entering same information because of web form behavior after they want to add new customer ? is their away in using Jquery to clear the form for new entry ??
I am using cookies to track form data the user inputs. The data only needs to be available during their session. I have well over 80 fields. How can I combine some of the cookies to cut down on the amount. I am storing them with JS and retrieving them with php.
I am wanting all the inputs of the table cells turn red when invalid data (in this case anything other than a number) is entered. Object:
1. To add a className to those inputs 2. With the new className 'invalid" the CSS gives a red background to the input The appending of the className is not showing up in the generated source code and both Firefox and Chrome is not showing any errors in the code. I can't not figure out what is preventing the execution.
I have a small piece of code (taken largely from W3 Schools)that checks that there is a decimal point entered in a form field, but what I really need is to check that the number entered ends in 2 decimal places.
e.g. 10 is Invalid 10.00 is Valid
My current code is below. Can someone explain what I need to do to ensure that the user enters a number including two trailing decimal places please?
I have a intern page with a form. User should enter their data and send the form. Some data from the user is stored in a database (name,phone). I want to make the form easier and complete the form with data from the database. The user should only enter his personal-number. How can i solve this with jquery? Is there any plugin?
Is it possible to convert an item of form field data to uppercase using the toUpperCase() method? What I'm really asking is, how do I reference the data item?
Ive got a form with 3 text fields, one for first name, last name and one i dont what the user to be able to write things in(if that cant be done no biggy), when I hit submit, I want to move these two entries (first name and lastname) into uneditable text field so basically just combine the two, and then the user can add more names and it just keeps adding them to the end of the other text field... kinda hard to explain, basically like a chat type thing, where hitting enter just adds more names to the other text field except only you can see it.
I've been building up my validation using the jquery validation plugin but I can't work out how to get a failed validation to default the focus to the first invalid input rather than to the last selected input. If there is no input field selected, when I submit then a failed validation will focus the cursor on the first field but if the cursor was left in a field and submitted then the focus stays there (if it's invalid) rather than jump to the first invalid input. From what I've read and seen, this is the expected behaviour but not what I want. Is there a way I can get the first invalid field and set the focus to that?
what i want to do is have a selection from 'tst' trigger an input into 'choose' from the data inputted into the 'fname' and 'lname' fields.
for example, i want option '1', when selected to draw the input from 'fname' and place it into 'choose'
or i might want to select the data in 'lname' instead, so i will tie option 2 to it, so when the user selects option 2 the contents of 'lname' go into 'choose' instead.
I'm having users fill out a form where there are multiple rows of data.
Some of the rows can have duplicate data for some fields.
So say on line 1) i have first name, last name as an input fields and some other fields as well, c, d, e, etc.
When the user gets to line 2) if they want to have the same first name and last name as line 2, can I have them check a box and it will automatically populate these fields with the info they just typed in line 1? I can't figure out how to do this.
I need the value of my drop down box options to contain size information rather than price. However I would like to be able to calculate a price for the items based on what size the user selects as well as the quantity. Below is the code I came up with (which doesn't work obviously)What can I do to get this to work for me?
I am working on a javascript code for validating phone numbers against 0's.The scenario is that, 1 ) If the phone number contains all 0's in it, an error message is displayed. Eg. 0, 0000, 000-000-0000, 000,0000000000 etc..2 ) Phone number should only take digits [0-9] and some delimiters ()-,.+ "All other alphabets and special characters are not allowed.Eg. 01, 102-125-0214, etc.. ( allowed ) sjjlkjkj, xllfs -09-49- ( not allowed )3 ) The code I have written is as below -
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml">
I'm having difficulty getting these two items inline. I wonder if anyone would give it a try. There seems to be a padding or length to the Search field that jumps a significant amount to the right.
I've always had this limitation when adding inline content using JQuery. Such as adding one more text field inline let's say. Basically, if I had defined some code related to input fields outside the scope of the function that adds the inline code, this new input field will not recognize it.
Something like
Code:
However, Ive always solved it by adding the click event another time after the code in placed inline
Code:
But I'm trying now to avoid this repetition, how is it possible?
I have an ajax function which passes form field values to a PHP script which in turn saves the data to my database. all works great.
I now need to add a file input to my form and pass the file upload ot the same PHP script.
I have read an article [url] which explains how to do this but this would suggest it is a completely separate function.
My question is, is there anyway I can expand my existing function (below) to inlude the file upload process to save having 2 functions doing the same process?
