JavaScript - Passing Form Inputs With Javascript
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. Similar TutorialsI 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:

</p>
<input type="submit" value="Submit" /><br />
<textarea cols="10" rows="3" name="output"></textarea>
</form>

Hi all, 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 -------------------------------------------------------- grand total -------------------------------------------------------- The JS code which passes the grandTotal variable is as below: Code: function ($this){
// sum the total of the $("[id^=total_item]") selector
var sum = $this.sum();
$("#grandTotal").text(
// round the results to 2 digits
"₹" + sum.toFixed(2)
);
}
The problem I have is the above grandTotal displays the final value when put into a table like below: Code: <td align="right" id="grandTotal"></td> But I am unable to make it work by passing it into a variable within the form fields. I would like to do something like this: Code: <input type="text" name="grandTotal" id="grandTotal" readonly="readonly" /> Can somebody please help me fix this? Any help will be greatly appreciated. Thank you.

When hitting next, previous, or submit it passes the values of all the questions to the next page. I've got the whole thing working correcting except for one thing: When the box is "not" checked it passes no value. I'm needing it to have a value of "1" when checked and a value of "0" when not checked, and currently when its not checked and i pass the info it leaves it blank. I'd post the whole code to one of the pages but it's long , so i'll post the snipits of the code. Code: <script type="text/javascript">

The first case that i showed in my code is a radio button, and it passes correctly, i just wanted to show the "format" i was using in a working sense. The 2nd case is an example of the check boxes. Thanks for looking at this, and giving any suggestions you might have! Is it possible to have an input that points to some other function? For example: Code: function someFunction() {
alert('It worked.');
}
function doAnotherFunction(doIt, otherFunction) {
if (doIt == true) {
otherFunction();
}
}
<input type="button" value="test" onClick="doAnotherFunction(true, someFunction());">
Or would I need a switch statement and have all the various functions hardcoded? 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. 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?
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-');
}
/**

* @param string cookie name
* @param string cookie value
* @param string cookie expiration counter in days
* @param string cookie path

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" : "");
}
/**

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));
}
/**

* @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);
};

if (old_value && old_value != '') {
el.value = old_value;
}
}
}
}
Does anyone have a solution? I would really appreciate it :] Here's part of the code, problem I have is I have it set up for 5 rows, I need it to be able to make more than this, but not sure how many more, this is dependent on user input, how should I go about this? Also how would I go about making the users orders correspond with the right item number? I'd need to sort the array somehow? document.write('<table border="1">'); document.write("<tr>"); document.write('<th colspan="5">ORDER</th>') document.write("</tr>"); document.write("<tr>"); document.write('<th align="left">Item #</th>'); document.write('<th align="center">Name</th>'); document.write('<th align="center">Price</th>'); document.write('<th align="center">Quantity</th>'); document.write('<th align="center">Total</th>'); document.write("</tr>"); document.write('<td align="center">0</td>'); document.write('<td>' + productName[0] + '</td>'); document.write('<td> $' + sausagePrice + '</td>'); document.write('<td> ' + orderItemQty[0] + '</td>'); document.write('<td> ' + sausageTotal + '</td hello all, i'm newbie in javascript fucntion. here i got problem to passing the value from child popup form to parent form. here my code parent form Code: <script language="JavaScript">

Hello Guys, I have a page with thumb nails and a large image that changes when clicking on thumbnail. I need to display dynamic title for the image. It wont display because the page is not reloading.. How do you pass the name so it will show up without reloading? Here is the JS for switching dynamically loading the large image PHP Code: <script language="javascript"> $(document).ready(function() { $('.thumbnail').live("click", function() { $('#mainImage').hide(); $('#atitle').hide(); $('#imageWrap').css('background-image', "url('/images/ajax-loader.gif')"); var i = $('<img />').attr('src',this.href).load(function() { $('#mainImage').attr('src', i.attr('src')); $('#imageWrap').css('background-image', 'none'); $('#mainImage').fadeIn(); $('#atitle').fadeIn(); }); return false; }); }); </script> Here is the link for the thumb PHP Code: // Thumbnail Display echo '<a href="artists/'.$artist.'/'.$imgname.'.jpg" class="thumbnail"><img src="artists/'.$artist.'/previews/'.$imgname.'.jpg" border="0" /></a>'; [/PHP] Link to the large image PHP Code: // Large image display echo '<img src="artists/'.$artist.'/'.$first_image.'.jpg" alt="Main Image" id="mainImage"/>'; Here is the php echo for the title PHP Code: <? echo str_replace('"', '`', $iname); ?> I need to some how pass a php var from the thumb link to the js and have it display dynamically(without reloading) Hope I explained this correctly..

I want to select some data from a database (photo names) and then show pass the information to a JavaScript to display the images on at a time moving onwhen a user click on a 'NEXT' button or back one when the click on a 'BACK' button. Does anyone have any idea on how to do this or is it something that is just no possible? i, Am developing a webform using PL/SQL. Am using javascript to do some form validation Sample if(a =="") { alert("Please enter the first name"); return false; } else if(b =="") { alert("Please enter the last name"); return false; } else if (y !="Test1") { if (y != "Test2") { if (y != "Test3") { alert("Enter the right text"); return false; } } alert("am wrong outside"); } else if(z =="") { alert("Please fill al the fields"); return false; } it passes till alter("am wrong outside") and executes the procedure but doesnt goes to the last else part. I want it to go the last else part too. Please help. Hi, I hope someone can help me! I have a list of buttons, each with a different id which is taken from the ids of these values from the database. When I click one of the buttons it shows the items that correspond to this id in the database. Therefore, when different buttons are clicked the display changes to match the objects relating to this particular button. When a button is clicked, this shows various other objects which I can then select (using a checkbox). When a checkbox is clicked, a Javascript function is called to change the html text next to the appropriate button. However, I can't get this to work as I need to pass the id of the button, and the html span, to the Javascript in order to change the correct text. Here is my Javascript : Code: function questionnum(checkbox) {
if(checkbox.checked) {
var qdesNumElement = document.getElementById('<?php echo $q;?>');
var qdesNum = qdesNumElement.innerHTML;
qdesNumElement.innerHTML = ++qdesNum;
}
This code only gets the last button. Please help. i've got a project to be done using javascript and html....i don't know how to pass the arguments from <input type="text"> to the javascript function i'm using in my program. i just want the javascript script to calculate the input given by the user and return the answer. here is the program: Code: <html>

pls it would be of great help. Thanx. Hi, I'm having one javascript function which will return the variable and I need to pass that variable to command button action.Please find the below code and let me know how I can achieve this. <script> function addEntry(entries) { var uploadedEntry = entries[0].entryId; alert("Uploaded Entry Details::::" + uploadedEntry ); } </script> <h:commandButton tabindex="1" image="../img/submit.gif" action="#{portfolioListing.uploadMediaEntry(uploadedEntry)}" Thanks, Anil Hello! I have a question about a concept I'm working with. I want to create an html page that displays several links to different pages on the site. The user would then be able to drag and drop these links into some sort of list. That part I have figured out. Once they've finished creating their list, they would be able to click on the links in the list. The question I have is this: if they click on a link in the list and go to that page, can their list again be displayed on the new page along with the items they added to it on the previous page? If this is a simple cookie thing, that is awesome. I can't utilize a database or anything server-side for this. HTML and javascript only. Any help would be hugely appreciated, as my programmer is out today.
