JavaScript - Change Form Depending On If Js Is Present Or Not
I have recently installed google custom search on a page- using the iframe selection, so I can have control over the look of the page and it isn't a google branded page.
The problem is- with JS disabled, this form doesn't work. However, the option to display results on a google hosted page does work. This is very important for accessibility for this site, so what I am wanting to do is have the basic search show ONLY if there is no JS enabled. But for everyone else- it displays as I intended. JS isn't my bread and butter, but I think it's the tool to use here. Could someone offer some guidance? Main Form Code: <div style="float:right">
<script type="text/javascript" src="/js/main.js"></script>
<div id="searchBox" class="searchBoxTopLevelNav">
<form name="search" id="search" action="search.php?">
<label for="q" style="display:none";>Site Search</label>
<input onclick="javascript:SearchClear(this);" onkeypress="javascript:OverrrideForms(this);" name="q" id="q" autocomplete="off" class="GoogleSearchTextBox" value="Search" />
<input name='btnG' onclick="javascript:SearchGoogle($(this).prev('input.GoogleSearchTextBox:first'));return false;" type='image' value='Search' src='../img/icons/search-gray.gif' alt='Go' align="top"/>
</form>
</div>
Form to display only if JS is not enabled Code: <form action="http://www.google.com/cse" id="cse-search-box">
<div>
<input type="hidden" name="cx" value="#" />
<input type="hidden" name="ie" value="UTF-8" />
<input type="text" name="q" size="31" />
<input type="submit" name="sa" value="Search" />
</div>
</form>
<script type="text/javascript" src="http://www.google.com/cse/brand?form=cse-search-box&lang=en"></script>
Similar TutorialsHello I've been struggling trying to get a small order form to work the way I want it to. Here is a link to the live page: http://www.watphotos.com/introductio...otography.html And here is the code in question: Code: <script src="js/jquery-1.4.2.min.js" type="text/javascript"></script>
<script type="text/javascript" charset="utf-8">
$(document).ready(function(){
var initial = 0
var total = 0;
var services = 0;
function addServices()
{
initial = 150
total = initial
services = 0;
$("input:checked").each(function(){
value = $(this).attr("value");
services += parseInt(value);
});
}
$(function()
{
addServices();
total += services;
$("form").before('<p class="price"></p>')
$("p.price").text("Total Price: US$" + total);
});
$("input:radio, input:checkbox").click(function () {
addServices();
total += services
$("p.price").text("Total Price: US$" + total);
});
});
</script>
I have two questions... Question 1 How can I make this piece of script act a little smarter. Look at the order form, I'm catering for up to 4 people and providing lunch for them. If they select 3 people and the spaghetti bol for lunch, it's only adding $10 where it should be adding $30. Obviously this is simple multiplication but since the values in my form are prices it makes it a little tricky. I'm guessing an onselect on the first part of the form which changes the pricing of the other items would be the way to go, but how do I do this? Question 2 The "Total Price" is placed before the <form> tag by the script. This is ok but it's not where I want it. How can I position this text elsewhere in the document? Thanks in advance! I'm still a relative noob and i'm wondering if anyone can help. items use a structured form, so any item in that category will display on the same form when selected i want to have the save button run its normal save on all items except 1 specific item - on the 1 item i want to have it function as a save as copy (while still having "save" as its visible text), the current code set in a drop down list is $options[] = array( 'text' => 'JSAVE', 'task' => $this->getName() . '.save'); $options[] = array( 'text' => 'Save as new project', 'task' => $this->getName() . '.save2copy', 'options' => array('access' => ($this->item->id > 0))); can anyone offer any suggestions? really stuck on this one I'm trying to use javascript to have my webpage black at night and bright blue (#2A7FFF) in the day time. How would I go about this? :/ I have also tried to use javascript to change a picture depending on the time of day, this is what I have used. IN THE <head> Code: <script type="text/javascript">
var hourofday = thedate.getUTCHours();
function sun()

// return TRUE if it's day
if (hourofday > 7 && hourofday < 10) {
return true;
}
return false;

{
// return TRUE if it's day
if (hourofday > 7 && hourofday < 10) {

}
return false;
}

Hello everyone Background I have an electronics site on which I have a code generator. Im an stuck on how to acheive something. I will simplify what I want to do, so I can then adapt it to my code. I have a paragraph of text on the web page, on which I want to change some words with in the paragraph depending on 2 radio buttons. Example (radio buttons & short paragraph): (Radio Button) Apples (checked) (Radio Button) Bananas "Welcome to jakes fruit shop. You have selected apples today" (apples being the word that would change if the banana radio button is checked) Here is the code generator if your interested. http://www.jakeselectronics.net/conf...erator877A.php What I actually want to do is put other 'fixed' text in the input text area (near botton of page) with only the config line changing. And If I can be shown how to do the short example above, i think I will be able to edit my generator and get it to do what i want it to do. Hello. The code below lets a user select a drop down option and a picture changes depending on the selection. I am trying to make it so when you select an option on the dropdown the picture shows up in the center of the screen and in the background behind the text. Here is the code. Code: <html>
<head>
<style type='text/css'>
#txt {background-repeat:no-repeat;width:200px;height:200px;}
</style>
<script type='text/javascript'>
function div_bg(team){
document.getElementById('txt').style.backgroundImage="url(images/" + team + ".jpg)";
}
</script>
</head>
<body>
<select name='team' onChange='div_bg(this.value);'>
<option name='arsenal' value='arsenal'>Arsenal</option>
<option name='liverpool' value='liverpool'>Liverpool</option>
</select>
<div id='txt'></div>

I only included the first part of the html code along with the first table, but there is a table for each xml file. You can also probably tell how the XML files are structured by looking at the way they are displayed in the tables. I think what I want to do can be accomplished with JavaScript, but I have no idea how to do it and it's the only thing I have left before I'm done. Any help would really be appreciated and thanks in advance. Hello, I have a form that works out some basic math questions e.g. area etc. I run a function when a form field is updated to do the calculations, however I'd like to run a different calculation depending on which form element was updated. Is there a way to say something like: if (area1 was updated) { work out this calculation } if(area2 was updated) { work out this calculation } and so on? Thanks, Nicola From my main page, I have a dropdown-login box. Is it possible login form go to my user's control panel if the login was successful, or go to the login page if it's not? Ideally, I don't want to use a re-direct. Do I need to use ajax? Thank you! I am thinking this should be fairly easy but yet I am not getting far. I want to have a form with a single text imput field for a zip code. Depending on which zip code the user enters will determine which url they will be sent to. If they enter a zip code which is not in the script, they would be sent to a default url. I am also assuming this can be accomplished with javascript. Any help is greatly appreciated. I'm trying to create/find a script that will do the following: -load a css file regardless of any conditions. -do not load the css file if a certain text is present in a specified html div tag. i know this is done with a if/else state like this: Code: if (condition)
{
code to be executed if condition is true
}
else
{
code to be executed if condition is not true
}
but I do not know how to add the condition for the variable text and to specify the css file. I want the javascript to ignore loading the css if a div tag like this: Code: <div class="menu-opener"><a class="gwt-Anchor" href="javascript:">Text1<img src=..//img.jpg"></a></div> contains the word Text1, or any other I specify. Else, if any other text inside the div, the css should load normally. I believe this is not difficult for a js knower and I would be very grateful for a solution. I'm a long time lurker on here just barely created an account to ask this question. I work at a call center, and we use different webapps to fill out tickets. One I've used for a long time allows dynamically updating forms with javascript. I have a whole bunch of bookmarked javascript injections like: Code: javascript:if((top.detail.findObj('X31').value="Inquiry")!="");
That code will fill out most everything in that ticket, leaving me to fill in the details. I have one of those for all of the most common tickets, and can create and finish a ticket in less than 30 seconds when it takes others 3-4 minutes. I recently switched to a different system and I'm having trouble with my code. I'm a noob at javascript for sure, but I'm not new to programming. Anyway any pointers would be nice. The system we use doesn't allow me to see the source... I'm not sure how to explain it. It loads everything in a frame. In chrome I can right click then inspect element and get the ID but it the above javascript doesn't work. Examples: Old app source ex: Code: <label for="X31">Category:</label> was all i needed new app(before the body code is just code for the login form, etc): Code: <body onLoad="startit()" onUnload="stopit()">

I'm setting up an application that involves blog posts with comments boxes appended to the div that contains the posts. The comments boxes are in iframes and load an html file on the same domain. There are multiple posts/boxes on each page. I need a javascript that will only run the append script when the posts are written and appear on the page. So in non js language, I'm looking for this: if div id post#5 appears on the page, show the iframe that contains the comments box that goes with post number 5. else don't show it. I don't know enough javascript to figure this out so if anyone could point me in the right direction, I'd be grateful. Hi Guys i am a complete novice at ajax or javascript. I have been studying php for a while now and i know that, i am now starting php oop and that going well but i have never done anything like this. Anway i am creating a booking system which at the end of the process asks who supplied your voucher which they then select a supplier. The issue i have is my client wants it so if groupon is selected then an input text box should appear so that the user can input a security code from groupon. So basically it is Code: <select name="supplier" id="supplier"> <option value="">please select supplier</option> <option value="Groupon">Groupon</option> <option value="KGB Deals">KGB Deals</option> <option value="Other">Other</option> </select> So if value="Groupon" then Code: <input type="text" name="security" id="security" /> should appear next to it. Could someone please help me as the page cant refresh as it will lose its data which would have taken the user about 10 minutes to fill out Thanks in advance Sorry for my beginner question but I am having some trouble getting this to work. I am trying to create a simple I=PRT calculator so it can calculate interest. But when you run it it adds the digits. Ex. 5+100=5100 instead of 105. Give it a try. My code is bellow.[CODE] // JavaScript Document alert("This is a simple calculator which will allow you to calculate the interest on a principle."); var principle = prompt("What is the amount you would like to calculate interest for?"); var rate = prompt("What is the interest rate. eg. For 3.9% write 3.9"); var term = prompt("How long in the period under calculation going to be? eg. For 1 year write 1"); var interest = principle*(rate/100)*term; var result = principle + interest; var a = "This means the interest is going to be $"; var b = " And the total to be paid is $"; var c = a + interest + b + result; alert(c); [CODE] Thanks in advance.

hi, Can any one tell how to change action attribute in form tag using javascript. thanks in advance regards sugeet Greetings, I'm working on a php/mysql app that has multiple tabs with multiple form fields. I am trying to incorporate a javascript form field detection function that alerts the user that they have not submitted their changes if they try to navigate away. The detection works as designed, but the problem I am having is when the form is submitted, the script senses an unload and still fires the alert. The form submits to itself and updates the database and then reloads the page with the new values. Is there a way to have the script ignore the forms submit url and skip the form check? Here is the code ( NOT mine, found it somewhere else.) Code: <script language="javascript">
var ids = new Array('description');
var values = new Array('<?php echo $detail['description']; ?>');
function populateArrays() {
// assign the default values to the items in the values array
for (var i = 0; i < ids.length; i++) {
var elem = document.getElementById(ids[i]);
if (elem)
if (elem.type == 'checkbox' || elem.type == 'radio')
values[i] = elem.checked;
else
values[i] = elem.value;
}
}
var needToConfirm = true;
window.onbeforeunload = confirmExit;
function confirmExit() {
if (needToConfirm) {
// check to see if any changes to the data entry fields have been made
for (var i = 0; i < values.length; i++) {
var elem = document.getElementById(ids[i]);
if (elem)
if ((elem.type == 'checkbox' || elem.type == 'radio') && values[i] != elem.checked)
return "Your changes have not been saved. Are you sure you want to leave?";
else if (!(elem.type == 'checkbox' || elem.type == 'radio') && elem.value != values[i])
return "Your changes have not been saved. Are you sure you want to leave?";
}
// no changes - return nothing
}
}
</script>
The url of the page is "edit.php?&mode=edit&t=2&id=284&cn=2009-002" The only detectable change to the query string would be the 't' variable. Basically what I want to do is have the script look for a change in the 't' variable and if detected, check the form values for changes. If 't' doesn't change, skip the script completely. Thanks.. Okay I have searched google for hours literally without luck so hopefully someone here can help. What I am trying to do is when someone submits the form if there are empty textboxes change the textbox's style from class="input" to class="inputreq". Someone please help, the formname is "signup" and the textboxes are "domain" and "username". Please help. Thanks. |
