Read And Write A Field Variable / Value Before Form Submission?
Aug 24, 2010
I was wondering if there was a way to dynamically read a field input and respond to it later in the form. My situation is this: I have a question that asks how many workers are employed at a business. Later in the form, the user is asked to add as many workers as they have (section with information on each worker) ..Is there a way I can have something echoed or document.write above the latter section saying "Please add (Number of workers listed above) sections for each worker employed"
I have a form that, during submission to another page, uses the submitted text field data and creates a cookie. But how would I do that with a radio button/checkbox field or pulldown? Just fyi, the code is created using onsubmit() and processes this before the response page.
All demos I see are for self submitting (same page) scripts. Not for those going from form.php to response.php and I cannot use this type of submission and find a value for a NON text field. I need to recognize non text fields since I want to create cookies for all form fields, not just text fields.
The code I have, to read the value of a text field is here: var email = document.myform.email.value.split(' ')[0];
I just want to have something similar to above, using 'myform' as the form name, but able to get the value for any *non text field*
is this possible? The rest of the code I won't post as it isn't relevant. I just need to read a value of a non text field and I can work with that.
I have email, password and some other fields, and I'm using $.post to send data for Ajax submission.
The problem is that I don't want to submit a particular field. The serializeArray() returns all the fields in the form. So, I tried something like this to prevent the password field being serialized.
This works great but the ajax submission doen't work.
I wonder if anyone can assist me here. I am trying to find the best way to validate a field against another field. In this case I need to make sure when the user enters the date of birth that the date is not prior to another date in the database (admission date). I would like to do the validation on submit before the other data from the field is submitted to the database.
I have seen a lot of forms validation that can compare the inputted value to a range of values, but I need to say "is the birth date prior to the admission date? If NO then give a message to the user to recheck the date". Sounds easy, but I haven't found a clean way to do it.
Currently, the Code will open the child window, show a search box, search for the database and display links, when you click on the link, the parent window will show the variable passed. My question is, how would i change this so that each of the variables displayed would have a php variable that i could submit with a form?

I want to bypass from one input field to other one by <enter> (<return>) key pressing instead of default behaviour (<tab> key pressing).But there was default form action on <enter> keydown event was performed. Remember that <enter> keydown event on form means default "Form submit" action. How to prevent default action, form submission, in time of <enter> keydown event processing?
How to modify following code? I use hotkeys jQuery plugin for key binding to input fields.
$().ready(function(){ $(myInputFieldsSelector).bind('keydown','return',function(evt){ //find next input field in the form MyNextInput MyNextInput.focus().select();
i am trying to pass a javascript variable into URL ..but not getting the value..var newID = 2;row.insertCell(6).innerHTML = "<a href=Update_Gate.cfm?GateIdVar=newID>Edit Gate</a>";i am getting"newID" in Update_Gate.cfm page ...i want to pass this javascript variable in url and read it on the other page as form field value

I can't seem to get an alert to show me anything. The eventual result is not an alert, but a document.write to post the url contents to various form fields for firstname= and lastname= etc.
I am really having a hard time using the document.write function, and am not sure how to employ it, whether in the same script statement or in a separate script in the body.
I have been trying to write a script that allows a user to click on a button like a plus sign to add an additional field for a phone number when they have more than one phone number to enter. I have created a script that sort of does this. It doubles up what is already there, so, the first time, everything is fine, but after that I get a lot more fields than I want. I am a php programmer and not familiar enough with javascript to get to what I want. My script is included below. What I am doing here is retrieving the html content and then adding it to what is already there. In php I would use an if conditional test to see if the data has been retrieved.
The first time it would retrieve the data into a variable. After that it would not retrieve it. I think I am getting into some scope and sequence issues here. Javascript is a bit different than php in these regards. Also there is a commented line in the code that asks another question about the use of variables that I don't understand. I also tried using appendChild() here to no avail. I couldn't get that to work at all.
I have a script that i need to read the ip from a visitor and set a cookie, so the script will never be executed again for that particular ip address.
Right now i'm having problems with the current cookie set of my script, i can't seem to make it not appear again after it's executed (which is my goal). That's why i want to try using an IP cookie, and see if that works.
Basically am going to make an search script to my website. I am going to use onkeyup event when the user is writing and my problem is that I wont to make a function that takes in input from the user and put it in the url. So I need to be able to write and read from the url without refreshing the page. I've managed to do this using window.location.search but I cant get it to work because the page keeps refreshing.
I am using a standard javascript that I downloaded from javascriptsource.com to read from and fill in a form using cookies. The page tests well in every browser except Apple's Safari (from 10.3.2)
Unfortunately, my clients daughter uses Safari so I have to get it to work with it, even though most of his clients use IE.
What do I need to do to change the code so this will all work in Safari? Code:
I have now learned how to write to and read from .txt files on my server via php, but is it possible to do this with JavaScript? Like that JavaScript writes to the .txt file every second without needing the user to refresh the page to write or read .txt file (with php). 2: Do the same thing with ActionScript 2/3.
Is there a way I can read my address bar and write the link to a file. I think it is great that websites post the code I need but the cut and paste thing gets to be a drag. If I am using my browser I am not editing my site. I need a way to save from the http and com. are maybe the part between the two dots.
i have a form with a 'name', 'date', 'type', 'style', 'color' and 'result' field.let's say the user inputs "jones" in the name field, "8/1/2011" in the date field, "new" in the type field, and 'modern' in the style field.i want the 'result' field to take a look at the 'name' field, and if the 'name' field has a particular text, let's say (in this case) "jones", the javascript code will then place the contents of 'date', 'type' and 'style' fields, along with hardwired text like "the information you are looking for is 'date', 'type' and 'style'" into the 'result' field.
I can't find any javascript that reads and writes cookies with keys, so that it is compatible with ASP (I want to read and write cookies from both javascript and ASP)
for example in ASP: <% Response.Cookies("user")("firstname")="John" Response.Cookies("user")("lastname")="Smith" Response.Cookies("user")("country")="Norway" Response.Cookies("user")("age")="25" %>
I'm looking for javascript code that can read that information.
I am new to JS and usually learn by studying code posted online and modify it to have it do what I need. Recently, I used a totaling plugin for an online ordering form which does the below:
item1 qty(user input text) * preset price = total price item2 qty(user input text) * preset price = total price item3 qty(user input text) * preset price = total price
Tried searching but didn't seem to find a solid solution to my problem I'm trying to pass a value to an input form field, from a function. Here is my code
PHP Code: <script> function createDiv(sceneNum, startTime, endTime, dialog, notes)
