JavaScript - Best Way To Approach Problem W/ Multiple Form Inputs?
I have many radio buttons associated with questions on a page with Yes/No options. Depending on if Yes or No is selected (varies with question), I need to prevent the user from going off of the page and somehow "mark" the questions that are answered "incorrectly/not preferred".
I could probably put validation on each individual radio button and display a message when going off the page, but I'm looking to make this more dynamic. One idea I had was to put a function on each radio button's onChange event and build an array using .push() to construct the array with all the radio button IDs that are answered incorrectly. I ran into problems when deleting from the array when the radio button was changed back to a correct response though. What may be best is to somehow indicate which radio buttons need looked at when leaving the page and then run a function or case statement over all the radio buttons to build an object? I'm not sure what approach to take. Any thoughts are appreciated. Thanks. Similar TutorialsHi All, I am working on a page with a webform and a subform. I have two related tables where my main form will populate the one side of the relationship and the subform will be for the many side. I am thinking about using an HTML table to hold my subform fields with javascript to dynamically add rows for additional records. I am having trouble with the design of the form processing script, however as since the index on the parent record does not exist at the time of processing I can't think of a way to populate the link field for the child records. The only thing I can think of is to have my page's onload event create a "blank" record (generating the index and storing it in a hidden field) and then essentially make the proceesing script be an update rather than a create. This of course would involve creating some sort of delete function if the user leaves the page without submiting the form. I am not sure this is the best approach but it is all I can come up with. I am open to any ideas or guidance from the community on either my subform idea or processing script idea and I thank you in advance. Kind regards, Ken I need to style a checkbox, so I made it into two images behind a form with hidden inputs. On click the form takes input from the other form into the hidden fields and POSTs it. Then I use PHP to grab that POST and put it back into the original form. Here are some snippets of what I am trying to do: First form input: PHP Code: <input type="text" name="email" id="email1" value="<?php if(isset($_POST['email2'])) { echo $_POST['email2']; } ?>" style="height:25px;width:270px;" /> Second form input: PHP Code: <input type="hidden" name="email2" id="email2" /> Second form submit image button: PHP Code: <input type="image" src="img/Boxchecked.jpg" value="submit" onclick="fname2.value = fname1.value; lname2.value = lname1.value; email2.value = email1.value" width="20" height="20" /> The forms work fantastic on everything but IE, which does not save the field values. How do I fix the onclick event to save them in IE? Help is much appreciated. I have taken lots of programming classes, but am now taking my first web programming class and I am getting sooooo frustrated. I have done lots of looking on the web, but am still unable to figure out why I can not make this simple assignment work. I just need some help with getting something to happen when the user hits submit. What I really want is for a new page to appear with the message using the user inputs, but I would be very happy with just getting the input to appear in the text area that I put in or even for the alert box to pop up with the input. I can work on validation code after I can get some kind of output to work..... I posted everything (due to it's small size), including my attempts to see what is working. Here is the code I have written: Code: <html>
<head>
<title>Name and Age</title>
<script type="text/javascript">
<!--
function Submit()
{
alert("Does this do anything?");
var name = document.forms['NameAge'].elements[0];
var year = document.forms['NameAge'].elements[1];
var date = new Date();
var curr_yr = date.GetFullYear();
var age = (curr_yr - year)
alert("<h3>Hello, " + name + ", you are " + age + " years old."</h3>");
document.close()
/*if (year > curr_yr)
{
alert("You must enter a valid year!");
}
else
{
document.writeln("<h3>Hello, " + name + ", you are " + age + " years old."</h3>");
document.close()
}*/
document.forms['NameAge'].output.value = "<h3>Hello, " + name + ", you are " + age + " years old."</h3>";
}
-->
</script>
</head>
<body>
<h1>Name and Age</h1>
<form name="NameAge" onsubmit="Submit()">
<p align="left">Please Enter Your Name:
<input id="name" maxlength="32" size="24" />
</p>
<p align="left">Please Enter the Year You Were Born:
<input id="year" maxlength="4" size="24" />
</p>
<input type="submit" value="Submit" /><br />
<textarea cols="10" rows="3" name="output"></textarea>
</form>
</body>
</html>
I want to make a search form where inputs only appear if a certain selection has been made. For example the user selects "Green" then the input "X" appears, and if the user clicks "Black" then input "Y" appears. How can this be done? If so, can someone give me a basic example in code that I can use to copy off?
Hello everyone! Hi, I am a complete beginner at Javascript(started a few days ago) and was having trouble with some functions. I'm trying to get the inputs required to change based on an option selected in a drop down menu. I was intending to run different scripts based on whatever is chosen but when I ran a test using an alert function, I realized my code isn't working. I went online and found really confusing stuff like "running a for loop through an array to make a dynamic select feature". Still confused any help would be appreciated. My code thus far: Code: <html>
<head>

I have a JavaScript that remembers the values of a form by creating cookies for each input element onblur. I cannot figure out though how to exclude one input field from being remember. It would be document.getElementsByTagName('input')[15] Every time I try to add an if/else statement in using that line, the script doesn't work altogether. Code: window.onload = function() {
rememberFormInputs('rma', 'input-');
}
/**
* Set a cookie
* @param string cookie name
* @param string cookie value
* @param string cookie expiration counter in days
* @param string cookie path
* @param string cookie domain
* @param bool secure?
*/
function setCookie(name, value, expires, path, domain, secure) {
var today = new Date();
today.setTime(today.getTime());
if (expires) {
expires = expires * 1000 * 60 * 60 * 24;
}
var expires_date = new Date(today.getTime() + (expires));
document.cookie = name+"="+escape(value) +
((expires) ? ";expires="+expires_date.toGMTString() : "") +
((path) ? ";path=" + path : "") +
((domain) ? ";domain=" + domain : "") +
((secure) ? ";secure" : "");
}
/**
* Get a cookie value
* @param string cookie name
*/
function getCookie(name) {
var start = document.cookie.indexOf(name + "=");
var len = start + name.length + 1;
if ((!start) && (name != document.cookie.substring(0, name.length))) {
return null;
}
if (start == -1) return null;
var end = document.cookie.indexOf(";", len);
if (end == -1) end = document.cookie.length;
return unescape(document.cookie.substring(len, end));
}
/**
* Remebers form inputs after you fill them in
* @param string form id to remember fields
* @param string a prefix to prepend to all cookie names. (prevent naming conflicts)
*/
function rememberFormInputs(form_id, prefix) {
var form = document.getElementById(form_id);
var els = document.getElementsByTagName('input');
for (var i = 0; i < els.length; i++) {
var el = els.item(i);
if (el.type == 'text') {
el.onblur = function() {
var name = this.name;
var value = this.value;
setCookie(prefix + name, value, 90);
};
var old_value = getCookie(prefix + el.name);
if (old_value && old_value != '') {
el.value = old_value;

Does anyone have a solution? I would really appreciate it :] Hi and hope you can help, I'm doing some course work and the current lesson I'm doing is about substituting images depending on onclick functions. I've attached the HTML / JavaScript as a txt file, this is their sample file and it is rather bulky and repetetive. I was wondering whether it would be possible to simplify the code as there is a lot of repetition, there are 8 question functions and 8 answer functions, I'm wondering if this could be simplified into 1 question and 1 answer function. Thanks for your interest, R Hey guys, here's my code Code: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

Basically I want to make it so that if you click about, and about is open, once you click contact it closes about before opening contact? I'm not sure how to approach this though whether I should use if statements or something? I'm pretty new to jquery I'm learning JavaScript, but want to make an accounting program(site) for my brother. It will be backed by php and mysql. I've found that javascript doesn't "really" have multidimensional arrays. The ways I figure to collect name, address, phone, etc could be any of these: 1. Create a customer object (customer.name, customer.address) 2. Use the mutidimensional array that JavaScript does offer. (var customers [ [], [] ]) 3. Create bunches of variables (var customerName, var customerAddress) or any other method I have found (will find). The information will for a customer will be filled out via HTML forms, processed by JavaScript then sent up to the PHP/MySQL database. OR should I just use PHP to deal with these directly? My impression is to use client side technology as much as possible or is this wrong? -Matt I have the need to utilize a pop-up calendar about three times on one of my pages. I created the calendar in a separate html file, complete with jquery functions for pulling the date once a user clicks their desired day. What is the best approach to have that calendar pop up in small window that hovers on the page so that I can take the users clicked day and utilize it on the main page? Should I use the jquery load () function to load the calendar into a div on the main page? Or should I include the calendar file in my header? I'm just asking for some ideas and guidance. I'm almost positive this question will make you groan "neewwwbie!".... I have a simple javascript that decides which 'div' to make visible, based on another element within the html. What i want now is to create a page where someone can view all the possible divs in that javascript that might appear and edit them (including href's, ital, bold and image tags.) Much like a CMS system, but the information is within a javascript, not a database. I would assume it's possible. What's a good way to approach this? It sounds like Javascript cannot edit .txt files. Is there a way to have the user access and edit an .xml file and just pull that into the div tag, instead of text? Hello, I'm in need of some help. I have a form that I want to clone and add up to 5 duplicates with slight changes. The changes a Add a second question and another set of related radio buttons for only the duplicates. Change the title in the Header to increment by 1 ex. Header 1, Header 2... I also would like to make the form elements "id" and "names" unique. Also, continue to use the add and remove button at the bottom. I hope this is doable. Any help will be appreciated. I have included my existing code. NOTE: for a visual, I mocked up the the original form and 1 copy of the fields in the html, not to be used. Code: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"

-Cheers Hey folks, I hope everyone is having a good day. I'm in need of some code that will allow people to subscribe to multiple email lists. I would like for there to be a check box per choice and an input box where the email address would be entered. That way they can subscribe to one or the other, or both at the same time. I did a Google search and wasn't receiving what I needed. Any help would be much appreciated. Thanks!! gabe Hey everyone, I'm having a problem with a project i'm working on. We have a webpage setup to alpha page individual people with pagers at work. It is a simple form that submits to a php file on the pager server. I am working on creating a script that submits a alpha-page to everyone at once. There are about 120 different ppl in the company, I want the script to submit the form once for each persons pager. I'm new to javascript but have alittle programming understanding. This is what i have so far: Code: <html> <head> <title>Send a Page</title> </head> <body> <center> <form action="http://sendpage/pager/PageSend.php" method="POST"> <input type="hidden" name="ContactPagerNumberId[]" value="120"> <input type="hidden" name="PagemessageId" value="What are you doing?"> <input type="hidden" name="ScheduledDeliverydateId" value="2011-08-22"> <input type="hidden" name="ScheduledDeliveryTimeId" value="19:30:00"> <input type="hidden" name=ScheduledDeliveryAmPmId" value="selected"> <button style="width:140px; height:30px" type="submit" name="SEND">Submit</button> </form> </body> </html> The ContactPagerNumberId[] is the arbitrary value set to individual ppl's pagers. I'm not sure where to place the javascript code at. It doesn't seem as hard as I'm making it out to be. Any suggestions? I have a document that contains four forms. I want to run a function only in the form the user is currently in. I keep getting the "document.my_form_name is undefined" error. I've tried all sorts of ways of doing this but can't find a solution. Here's a snippet of the HTML: Code: <form id="my_form_1" name="my_form_1" action="some action" method="POST"> // in here I call the function onchange_display_sel_droplist and // pass through the name of the form </form> <form id="my_form_2" name="my_form_2" action="some action" method="POST"> bla bla </form> Here's the part of the function in question: Code:
function onchange_display_sel_droplist(my_value, my_object, my_text_obj, my_form_name)
{
// create array with all the divs found
var arr = new Array();
arr = document.my_form_name.getElementsByTagName( "div" );
// loop through array
for(var i=0; i < arr.length; i++)
{
var tagId = document.my_form_name.getElementsByTagName( "div" ).item(i).id;
// find all the divs with ID "my_selected_div__"
if ( tagId.indexOf("add_selected_div__") > -1 )
{
// hide all
document.my_form_name.getElementById(tagId).style.display = "none";
}
}
// display selected object (droplist)
document.my_form_name.getElementById(my_object).style.display = "";
}
hello guys! I need help setting up a form, I want to do some pretty neat things: It will say: What countries do you want to visit? [FIELD] Part 1: I want that when a user starts typing into the field, it will suggest under things that match what you have typed so far, sort of like facebook search does. So I would need a list of recognized country names. Now for example imagine I was using this, and I typed in M, it would list under a max of 5 valid entries begining with M, if I typed in Me, it would list the ones begining with Me, if I typed in Mex, it would show Mexico. Now the user would have to click this drop down suggestion to choose it. Part2: I want once a user clicks on a suggestion, it will "pop under" the input box or somewhere, with a "x" beside it to remove it. The user can now type in another country, and when it is clicked it too appears as a sort of "icon" under the input box or somewhere, with an "x" beside it. Clicking the x removes the country from the current list of countries. Once he is done, he goes on to other fields and the selected countries remain visible. Once a user submits the form, I want to get only the countries that were visible to him. **An alternative idea, if this one is too complicated, would be to have a drop list with all countries in it, and once a person clicks one, it will remain and a "+" sign will appear under it. When pressed, another dropdown menu will appear so the person can choose another country from the second drop down, etc. OFC all selected countries can have an X to remove them. Idk how to do this either.. I need help guys I have no clue how to do something like this, where do you recommend I start? Any ideas? I tried searching but I'm not sure what to call this so I couldn't find anything in the search. Thanks for your help so much!! Hello! coding forums gals, I am resorting to you for help with a html form that uses javascript to validate data. the form is an invoice for a trip order where the user can select a trip location out of a listbox, a number of people traveling, and where they wish to stay(ex. hotel, tent, etc.) after the user selects one for each category and hits the "add to invoice" button, the fields in the invoice should get filled with the corresponding information. Now my question is how can I write code that will insert information in the next line down and all other lines below if the user wants to schedule more than one trip at a time? basically what logic and programming structure do I need in my function that will know when the first line in the invoice is filled and will add data in the next line down. after I have successfully placed an order, and I want to make another one, how do I get javascript to output data on the second line?

I am somewhat a noob at js/jquery so I wasn't sure exactly how to do this. Think I just need a push in the right direction. Basically I'm trying to validate a form (jquery validation) with a couple of conditionals based on a selection box. So I have: Code: <form id="info" class="validate">
<select id="select">
<option value="senior">Senior Citizen</option>
<option value="adult">Adult</option>
<option value="child">Child</option>
</select>
<input type="text" name="age" id="age" class="required" minlength="1" maxlength="3" title="age group">
</form>
I'm trying to validate that if the user has selected "Senior Citizen" then their age must be 65 or older (and validate the adult/child ages as well). I hope to get this all in ajax so it would be checking it live. Thanks for the help! I am very new to javascript and cannot find any info anywhere regarding the following problem: On my website I have around 100 pages containing an action form. Occasionally it is necessary to cancel the action throughout the 100 pages which is very time-consuming. Then the action has to be reinstated once again for all the 100+ pages. I thought the solution would be to use javascript to change the action from a .js file which would mean only one page, the .js file, would require alteration: The action that appears on all 100+ pages several times that I am trying to change or stop happening by overwriting the "form action": <form action="http://www.changenamecart.com/" method="post"> <input type="hidden" name="userid" value="1234567"> <input type="hidden" name="return" value="http://www.thehomepage.co.uk/index.htm"> <input type="image" src="http://www.changenamecart.com/images/pic.gif"> </form> My efforts to date a The change .js file: function change() { var myChange = form action; if(myChange == form action){ document.write("form xction"); } } The html file in the header: <script src="change.js" type="text/javascript"></script> I am afraid that my knowledge of programming is very small and I would welcome any help to solve this problem. |
