Debugging Mad Libs, Accessing Text From Input Boxes
May 19, 2011
I've been playing around with a madlibs exercise while trying to learn simple javascript. I have three input boxes and a button display an alert containing the input from the boxes.
Am I right to be assigning variable names to the values from the text boxes and then referencing those variables in my alert?
I've been working on it for hours and can't get past this point.
Inset a name:
<input type="text" id="textbox1" size="10"/>
</br>
Insert a verb :

I have an in-house web application in which the user inputs items to a text field. Over 80% of all data entered into the field falls is one of three values, the other 20% is random. Can I make a select field that lets the user override the values with one of his own, or equally, create a textbox with a dropdown menu to select from?
The goal is to get the behavious of a web browser's address bar: the same control could accept random input, but also make suggestions in a pre-populated dropdown list.
Ideally, the control would work with and without the mouse, as the users are not confined to any single platform and we have Linux and Windows users as well.
I am not sure if this should be under JavaScript or CSS as the solution probably depends on both technologies.

I have a requirement where i need to take an IPv4 address as an input, my web page has 4 text boxes. If i have a address like this 255.255.255.255, my program jumps into the next text box without any problem as soon as i enter the 3 digits. i dont need to press any tab or any other key to go to next text box.
In case of an address like 12.24.12.3, i have to press <tab> to jump into the next text box, My project requirement says that it should work with '.' (dot) char as well.
SO here is my actual requirement i need to jump into the next text box as soon as user enters a dot (.) char without displaying the dot into the text box.

I have 3 input text elements:
<html>
<head>
<title></title>
<script type="text/javascript" src="../lib/jquery/jquery.js"></script>
[Code].....
When user inputs text to "text1" I want to reflect changes in "text2". When value is changed in "text2" I want to change value in "text3". So I handle keyup event in "text1" and then successfully update "text2". But which event need to be handled when value of "text2" is changed?
Important remarks:1. I don't want to update "text3" from "text1".keyup event. My goal is to handle some event when value in "text2" is changed(may be by user or may be by code)2. "text3" needs to be changed immediately after "text2".value changed

I have a form where a user enters a number in a text box (txtTickets). When that number is entered, I need to create an equal number of select boxes. I've found code examples which show how to dynamically add or delete options from a select box, but I have found no examples which deal with this specific scenario. The select options do not depend on user input -- that is, I do not need to populate it dynamically. I need to create them dynamically. Has anyone created something similar to this?

I have two Select Boxes on my web page, 2nd being populated based on selection of first select box. Now I am suppose to get the selected value of 2nd Select and put it in a link i.e.
Code:
<a href='abc.html?id=<2nd select box value>
I can get the selected value using Javascript with the following code:
Code:
2ndid = form.2ndodf.options[form.2ndodf.options.selectedIndex].value;
Where 2ndid is a global javascript variable.
How I can use this variable into <a href> tag.

I have a table (not in a form) that has several input text boxes. I want to have a reset button that acts like the form RESET button. I thought I would use the following jQuery method:
Here's my reset button code:
Here's one of my table input lines:
I thought this would be simple, but I can't seem to figure out how to target the text that the user types into an input field before he/she decides to "reset" and start over.
I'm thinking that my problem is that I can't find the correct syntax for my line: $('input.firstname').value('')

I have a problem created by my complete [rookie] status – only second time venturing into jQuery. I created a simple shopping cart using php and the PayPal buttons (1: buy now, 2: add to cart). The php back end does it great, it generates the table and the buttons and everything works just like it’s supposed to; Except, I forgot to add sizes. So I found out what I need to add, and I realize that the way the buttons work, I will have two different text boxes for size. Not very visually appealing, and since I’m not submitting this to the server before it goes to PayPal to pay, I cannot modify it with php the way I normally would. jQuery / javascript are my only hope of making this work. What I want to do:Have a single textbox where [size] is entered by the user.
Copy the value from the [correct] text box to the Value=”” section of the now hidden field in the PayPal form That way, no matter whether they [BUY NOW] or [ADD to CART] the right size is submitted to the PayPal shopping cart. This is the actual PayPal code that I’m trying to change
<table>
<tr>
<td>
<input type="hidden" name="on1" value="Size" maxlength="200">Size</td>
[code].....
I got this far, and then decided to find how to insert the "enteredVALUE" into the right place in the input text field (what I called output) and I've not been able to figure out how to stuff it in there.

In a project repeated blocks are identified by an <input type="hidden" value="x" /> field. To get an access to one of the block I wanted first access to that field. My first problem is there and I will explain it by a micro-project (tested with Firefox only)
Here is the HTML code :
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "[URL]">
<html><head>
<meta http-equiv="Content-Type" content="text/html; charset=utf8" />
<meta http-equiv="Content-Style-Type" content="text/css" />
<meta http-equiv="Content-Script-Type" content="text/javascript" />
<link rel="stylesheet" href = "index.css" type="text/css" />
<script type="text/javascript" src='Library/jquery-1.4.js'></script>
<script type="text/javascript" src='index.js'></script> .....
And here the javascript code wher is the JQuery question
//meta http-equiv content-type charset=utf8
function test(){
var $id = $('#curUnion').val();
var $objet = $('#toutesUnions > .pseudoFieldset').find('input[value=$id]');
var $test = $objet.val();
var $objet2 = $('#toutesUnions > .pseudoFieldset').find('input[value="1"]'); .....
With $id = "1" as shown by the Javascript debugger (in Firefox) where is the difference between find('input[value=$id]') and find('input[value="1"]')
Giving the alert result => undefined / 1
If you want to test the micro project you will find it in the Test.zip joined. How to access the immediate parent pseudoFieldset to get its html code?

Say I have:Code:
<div id="abc">
<input type="text" name="myname" value="TEST">
</div>
if I use abc.innerHTML, I won't get the new value for the text field (if changed by the user). What would be the best way to accomplish fetching the new value to "properly" copy the HTML?

I am looking to make a page with a display on it using input boxes, but I want the input boxes to get some of the values from an array I enter at the beginning. To start with I am only entering 2 items, as it will make it easier until I have it all up and running. I have no problems getting a table to come up, with a label and then an input box beside it. I can even prompt the user for the number of input boxes they require. I also can make it so that the input box is disabled, so that the user cannot change the contents of it. But, I am totally stuck as to how to get this how I want it...
I am wanting labels at the top of each row, not the left hand side, and I am wanting rows of 3 input boxes, with the first 2 containing the text from my array, which is what I'm wanting ti be the disabled boxes. Basically I am starting a very simple page for an online order facility.
This is the code I have been working on, I have totally messed it up by now trying different things but it will give an idea of what I have been attempting I figured lol. I have got it to have 6 empty input boxes all on top of each other, but I realised after that if i set all the values etc in the table, then im not getting the array to define the contents :S and, they are still all on top of each other which i dont want... And my attempts at getting the array to define the number of input boxes has so far been futile. I end up with a blank page, just a button. just getting frustrated lol.

I have an HTML file input control, like this:
Code:
<input type="file" id="FormsFileSelector" name="FormsFileSelector" size="40" maxlength="1000" style="width: 382px; white-space: pre;"
accept="image/gif,image/jpg,image/jpeg/,image/tiff,image/bmp"
>
And it does indeed allow the user to select a file on his computer.
But when I access the value of the control I get an odd value. I do this, in javascript:
Code:
var FileSelector = document.getElementById("FormsFileSelector");
var FileName = FileSelector.value;
And the FileName that I get is "C:/fakepath/MyPicture.jpg"
The actual path is C:/MyDocuments/MyPictures/MyPicture.jpg". But instead it's coming up with "fakepath".
Very weird! How do I get it to return the actual full path to the file on the user's computer?

I have a form with multiple input fields and I'm trying to identify the specific input field that is in focus so that I can display a relevant status bar message.
I have a message array with various entries in it and I'm calling a showStatus() function with an onfocus function from the form itself e.g.
The code in the input form =
<input type="text" name="first" size="31" maxlength="20" class="entry" onfocus="showStatus()"/>
The showStatus() function so far is =

I'd like to access the array variable of the item that is in focus not only for the message but also for an onblur function to validate input.

I am trying to use a code snippet fromthe code works fine however what I want to do is modify it so that when the user clicks the link to add another entry their would be a drop down <select> box to the left of the text input box. Which I have working but each time the link is clicked to add a new <select> and text input box row the previous <select> dropdowns seem to loose their values and only the text input boxes keep their values. So I am not sure where/how to edit my below code to work properly

I have two input boxes on a form which receive the first and last name of a user. I want to be able to use charAt() to get the first letter in each box and pass it a third box on the same form. is this doable? May I request some help? I was thinking something like the function below would be the starting point --I stand correct, as it is not working.
<script type="text/javascript">
var str="Mossa";
<!--document.write(str.charAt(0));-->
document.write('<INPUT TYPE=text size=2 VALUE="str.charAt(0);">');
var str="Barandao";

I have to input an undefined number of rows of data. Existing data is read from a database. There is an Add button after the last row.
I can see how to add the next row: there is a hidden blank row with visibility set to 'none', which is turned to 'block' by clicking the Add button.
How can I continue to add rows? Do I need to have a large number of invisible rows and turn each one on as required? (I don't want to have to submit the form for each row, which would be another solution).

Somebody asked me if it would be possible to add auto-advance to a web
form where there are a lot of repetitive 5 character fields. I took a
look around the web and found a script, which appears to work in the
couple of browsers I tried it in. However, when I look at the script it
appears to have the wrong number of brackets. Then when I changed the
script to the way I thought it should be, it still worked!
I'm totally rusty on javascript. I think I remember that you're allowed
to omit brackets when you only have 1 line following the if (or while,
or whatever).
A couple of questions:
Are the brackets in the original script below wrong or am I missing
something?
Can anyone recommend a different auto-advance script?
Or, is auto-advancing a bad idea all around from a usability/accessibility point of view?....

I have a page where you can dress someone up in silly clothes using a skeleton image, and several items of clothing as gifs in dragable layers. Code:
How can I use a bit of j'script to grab the X and Y values of each layer and then put them in to a load of hidden form fields?
I then intend on having the user click the submit button when they've put all the stupid clothes in the wrong places... and saving the results in a database.

i'm building a website at the moment with a user registration form. something i struggle with everytime is the best way to give feedback to the user (e.g. further instructions for a particular field or error messages).I saw a very nice execution of this recently at this site. /user/register - this looks to be a custom job, but i'm curious is the open-source or even paid plugins that do a similar thing.
