JavaScript - My Checkboxes Are Controlling One Another
Hi, I have a few checkboxes in a form. Some of them work independently, but some make the others go on and off. Specifically the lower ones are controlling the upper ones. Can anyone explain why please?
Code: <td> <input type="checkbox" name="weddingitem1" value="Toppers" id="Toppers"/><label for="Toppers" >Toppers<br /> <input type="checkbox" name="weddingitem2" value="Champers" id="Champers"/><label for="Champers" >Champers<br /> </td> Similar Tutorialsok guys, i am not very saavy with javascript and I dont know if this is an easy fix or something difficult, but here is my plan. I would like to have 4 divs with content in each and set each to occupy the same web space through absolute positioning. The .js would be for me to have three divs with a display:none and one to have display:block. and then at a set interval, have the divs switch role so that one that was display none is then block and the others are hidden. I dont want to have a page reload and I dont want to work in flash or anything like that, I just need an example of a script that will alternate through a set array of div ids (i.e. "<<div id="ad1"></div> div id="ad2"></div> <div id="ad3"></div> <div id="ad4"></div>, and change the display attribute every 10 seconds or so. Any help would be greatly appreciated thanks so much Hi, Im trying to change the position of a div when a button is clicked. The js is: Code: function curPos() {
objDivStrip = document.getElementById('thumbview');
return objDivStrip.style.top;
}
function up(pos) {
//get objects
objImgStrip = document.getElementById('str');
objDivStrip = document.getElementById('thumbview');
//Get End position
var totImg = (objImgStrip.height - 100) / 130;
var endpos = totImg * 130;
if (pos=endpos)
{
return false;
}
else
{
objDivStrip.style.top = pos - 130;
}
}
and the html on the button is Code: <img id="arrow" src="images/arrow_up.jpg" onclick="up(curPos());" /> The code doesnt work but if anyone could point me in the direction to get it to work your help is greatly appreciated. Cheers Sol Hello, I need your help. I have 2 checkboxes. How would I control one from the other? Eg. [ ] Option A [ ] Option B - If Option A was checked first and, I put a checkmark in option B then Uncheck Option A and leave option B checked. - If Option B was checked and, I put a check mark in Option A then uncheck Option B and leave Option A checked. How would that be written in Javascript, I am totally confused. Any help with this is much and foremost greatly appreciated. Cheers, J hi everybody; i'm using this code to trigger functions with left and right arrow keys.. but they work even if the arrow keys pressed in input boxes.. is there any way to prevent this code to work when user presses the arrow keys in input boxes? Code: document.onkeydown = function(evt) {
evt = evt || window.event;
switch (evt.keyCode) {
case 37:
geri();
gostergeyaz();
break;
case 39:
ileri();
gostergeyaz();
break;
}
};
Problem I have an index.html that sets up 3 Frames. They are called FrameTop, FrameA and FrameB. See pic below. In FrameTop the user can type in a url into a textbox with id="urlINPUT". When user clicks LOADA it loads that url into FrameA. User can then browse web in FrameA, clicking links etc and going to new pages. The second button LOADB is designed to determine the current location/url of the page displayed in FrameA and load that into FrameB. So far when I write the javascript in FrameTop LOADA works but LOADB loads the FrameTop into FrameB! [error!] If someone can please help me with this problem it would be much appreciated. This work is going towards a free website idea. I suspect my error lies in use of parent/self in the parent.frame.location. Here is my page layout. -----------------Index.html------------------------------------- <frameset rows="5%,*"> <frame name="FrameTop" src="frame_top.html" /> <frameset cols="50%,50%"> <frame name="FrameA" id="FrameA" src="frame_a.html" /> <frame name="FrameB" id="FrameB" src="frame_b.html" /> <noframes> </noframes> </frameset> --------------------frame_top.html------------------------------- <SCRIPT language="JavaScript"> function loadURLintoA() /*gets the url typed in by user and loads it into Frame A. This works fine*/ { var urlrequest= "http://"+document.getElementById('urlINPUT').value; parent.FrameA.location.href = urlrequest; /*sets FrameA location to url that user enters in frametop input*/ } </SCRIPT> <SCRIPT language="JavaScript"> function loadAintoB() /*I WANT this to get the url of the website loaded in frame A and load it into frame B*/ { var urlofA = parent.FrameA.location; parent.FrameB.location = urlofA; /*this is supposed to get the url of FrameA and load it into FrameB*/ } </SCRIPT> </HEAD> <body bgcolor="#848484"> http://<input type="text" name="urlINPUT" value="" id="urlINPUT" size="10"> <input type="button" name="loadAbutton" id="loadAbutton" value="LOAD A" onclick="loadURLintoA()"> <input type="button" name="loadBbutton" id="loadBbutton" value="LOAD B" onclick="loadAintoB()"> ---------------------------------------------- What happens when I run index.html index.html loads the index correctly and displays FrameTop, FrameA and FrameB. The load A button also works correctly BUT when I click LoadB it loads FrameTop into FrameB! This happens when no page is loaded into FrameA AND when an external page in loaded in. Please help, I would be very greatfull if you could point out my mistake. I am trying to use JavaScript to manipulate the appearance of a web browser. (1) Initially I need to identify and save the current browser settings (e.g. position, height, width, caption on or off, menubar on or off, border on or off). (2) Then I need to change the appearance of the browser to full screen, no border, no caption, no status bar, no menubar). (3) Finally, I need to return the browser to the initial settings using the settings saved at the beginning. I am a novice at JavaScript and am having a difficult time locating details of the language that permit me to accomplish my objectives.

... in which I would like to use Javascript to control the values in the 'padding'. Code: padding:318px 0 0 316px; May I know how can I use Javascript to control that 'padding' values? Appreciate any help. Good day/evening. I am trying to reload the contents of a div asynchronously using jquery. It works fine if the link/button to do so is outside of the div I am reloading, but I need the button to be inside the div I am reloading and it does not work if I do it from there. I have thought about overlaying divs but I need the buttons to be very exactly positioned as its a graphical representation of a map and recoding the way the buttons are placed would not only annoy me but be very difficult. You see its an isometric view of a square, and the buttons need to be placed right along the edges of the 'diamond' therefore always coming inside or on top of the div that contains the map view. So, is what I am trying to do impossible or might I just be going about it the wrong way ? If it is the latter then I will post some code. Thanks in advance. EDIT: sorry, I didn't see the frameworks forum for Jquery stuff, if a mod could please move this thread in there then that would be just fab. I am trying to do a custom add to cart to use with paypal and need to utilize javascript to achieve inserting some code or a weight value per the paypal forms' options choice. Here is my dilemma, All of my items have multiple weights, for instance the below example called Aqua Max 100 comes in .5lbs, 1.5lbs., 10lbs., 20lbs., and 50lbs. Paypal allows you to enter weight but it's one weight per item and I would have to create 5 Paypal buttons just for this one item to calculate the different weights per zip code. I need help making javascript insert the following code within the paypal forms' code upon option select before clicking submit? <input type="hidden" name="weight" value=".5"> <input type="hidden" name="weight_unit" value="lbs"> <input type="hidden" name="weight" value="1.5"> <input type="hidden" name="weight_unit" value="lbs"> <input type="hidden" name="weight" value="10 <input type="hidden" name="weight_unit" value="lbs"> <input type="hidden" name="weight" value="20 <input type="hidden" name="weight_unit" value="lbs"> <input type="hidden" name="weight" value="50 <input type="hidden" name="weight_unit" value="lbs"> The code I came up with is wrong as I'm getting an error but I was originally trying to make it enter a weight using a hidden fillable number and without any real javascript training, just alot of googling but I think I'm pretty close. Please take a look at the code I've came up with so far and maybe point me in the correct direction: <html> <body> <form target="paypal" action="https://www.paypal.com/cgi-bin/webscr" method="post"> <input type="hidden" name="cmd" value="_cart"> <input type="hidden" name="business" value="test@test.com"> <input type="hidden" name="currency_code" value="USD"> <input type='hidden'text' name='amt' id='amt' value="0.00"/> <table> <tr> <td> <input type="text" name="on0" value="Aqua Max 100">Aqua Max 100</td></tr> <tr><td> <select name="os0" onChange="getamt()"> <option value="select">Please Select</option> <option value="1/2 lb.">1/2 lb. $3.99 USD</option> <option value="1 - 1/2 lbs">1 - 1/2 lbs $7.59 USD</option> <option value="10 lbs.">10 lbs. $25.80 USD</option> <option value="20 lbs.">20 lbs. $42.75 USD</option> <option value="50 lbs.">50 lbs. $86.20 USD</option> </select></td></tr> </table> <script type="text/javascript"> function getamt() { var sh=0; var choice = document.getElementById("os0").selectedIndex; if (choice == 0) { sh=0; } if (choice == 1) { sh=.5; } if (choice == 2) { sh=1.5; } if (choice == 3) { sh=10; } if (choice == 4) { sh=20 } if (choice == 5) { sh=50.00; } document.getElementById("on0").value=sh; } </script> <input type="image" src="https://images.paypal.com/images/sc-but-03.gif" border="0" name="submit" alt="PayPal - The safer, easier way to pay online!" /> <img alt="" border="0" src="https://www.paypalobjects.com/en_US/i/scr/pixel.gif" width="1" height="1"> </form> </body> </html> Good evening all, I have a bit of an issue with checkboxes - basically I need to allow only 1 selection and then have a comments box show when a checkbox is checked. I've gotten the comments box to show when the checkbox is checked but I can't seem to workout how to allow only one. I'd really like the user to be able to change their mind and make a different selection but only have 1 be selected at a time (sort of like radio buttons work). I know it would be much easier and probably better to use radio buttons but that isn't an option with this. (The actual HTML is produced using a style sheet in an application that I am interfacing with so all I can do is use the checkbox.) Here is the code I am using to show or hide the comments box. Code:
function HideComments()
{
var a1 = document.getElementById("crmForm_answer1").checked;
var a8 = document.getElementById("crmForm_answer8").checked;
var a2 = document.getElementById("crmForm_answer2").checked;
var a3 = document.getElementById("crmForm_answer3").checked;
var a4 = document.getElementById("crmForm_answer4").checked;
var a5 = document.getElementById("crmForm_answer5").checked;
var a6 = document.getElementById("crmForm_answer6").checked;
var a7 = document.getElementById("crmForm_answer7").checked;
var a9 = document.getElementById("crmForm_answer9").checked;
var a10 = document.getElementById("crmForm_answer10").checked;
if(a1==true)
{
document.getElementById("crmForm_answer1_value").parentNode.parentNode.style.display = 'block';
}
else
document.getElementById("crmForm_answer1_value").parentNode.parentNode.style.display = 'none';
if(a8==true)
{
document.getElementById("crmForm_answer8_value").parentNode.parentNode.style.display = 'block';
}
else
document.getElementById("crmForm_answer8_value").parentNode.parentNode.style.display = 'none';
if(a2==true)
{
document.getElementById("crmForm_answer2_value").parentNode.parentNode.style.display = 'block';
}
else
document.getElementById("crmForm_answer2_value").parentNode.parentNode.style.display = 'none';

Thanks in Advance Sam Hi all. I have the following problem that I require a pointer with. I have a php variable named "$seatid" This could contain 1 or many entries. I have a page full of checkboxes named A1-8, B1-8, C1-8 etc to P1-8 I want a way of greying out the checkboxes on the page that relate to the values that are contained in the php variable. So they cannot be clicked. It would also like to change the colour of the cell that the check box is contained in. It is important that the checkboxes or at least the table that contain the checkboxes remain, as it represents the layout of a theatre. Cheers for your help have a simple calculator i made with checkboxes and some Js. the problem is that it does not work in FF. any idea how this can work for IE Safari AND FF Code:
function getPrice(amount, boxName){
total = eval() ;
checked = document.getElementById(boxName).checked
if (checked){
total = parseFloat(form1.Total2.value) + parseFloat(amount);
}else{
total = parseFloat(form1.Total2.value) - parseFloat(amount);
}
total.toFixed(2);
form1.Total2.value = total
document.getElementById("total").innerHTML = "Total $"+total;
}
My form generates 1 to n records which contains check boxes. Based on some condition if I click a check box it has to check & disable some other check boxes automatically. I did it. But, at the same time if I un-check I have to un-check all the check boxes which were checked. Please let me know. Thanks a lot.
All, I have the following code which validates a form has at least one checkbox checked before it submits it. However I want to make sure that there aren't more then 25 checked on the page. How can I do this? Code: function validate(field)
{
for (var i = 0; i < field.length; i++){
if(field[i].checked){ // if a field is checked form is submitted
return true;
}
}
alert("You need to have a check box selected to submit the form!");
return false; // if no fields are checked form not submitted
}
Thanks in advance! Hello. How can you modify this code so that if you click a checkbox that is ALREADY CHECKED, it will remain checked? By the way, I have searched the web on how to do this and the general consensus seems to be "use radio buttons instead", but I would not like to use radio buttons. I would like to use checkboxes, I think they look better for what I am trying to do. Thanks for any help Code: <input type="checkbox" id="ckbox1" onclick="if(this.checked){ document.myform.ckbox1.checked=true; document.myform.ckbox2.checked=false; document.myform.ckbox3.checked=false;}" checked="checked" />Best Match
<input type="checkbox" id="ckbox2" onclick="if(this.checked){ document.myform.ckbox1.checked=false; document.myform.ckbox2.checked=true; document.myform.ckbox3.checked=false;}" />All Words
<input type="checkbox" id="ckbox3" onclick="if(this.checked){ document.myform.ckbox1.checked=false; document.myform.ckbox2.checked=false; document.myform.ckbox3.checked=true;}" />Exact Phrase
irst post here, i'll try to be simple: I need to create a form where participants of a medical convention register to classes, each class lasts 3 hours, so a person who wants to attend to class starting at 10 am cannot register to 11 am, 12pm and 1pm classes, but he can register to 2pm and so on. There are 3 different classes per hour. i thought doing this using javascript, but i'm absolutely lost. Can you please give me a hint on how to do this?

(or if this one doesn't work is there a specific validation functions -your can recommend that are easy to use for all different types of input) I am trying to get a link that when clicked it will check all the checkboxes in my form. My problem is that my values are stored in an array: <INPUT TYPE=\"checkbox\" name=\"emailArray[]\" value=\"$email\"> print"<br><a href=\"#\" onClick=\"checkAll()\">check all</a><br>"; Here is my javascript function : function checkAll(){ alert('hi'); var df = document.selectEmailForm.elements; for (var i = 0; i < df.length; i++) { if (df[i].name == "emailArray[]" ) { document.selectEmailForm.emailArray[i].checked=true; } } } Any ideas? Any help is greatly appreciated. Thanks for your time! Hello, today I am trying to allow a user to easily uncheck/check all checkboxes in a form by checking or unchecking a checkbox. The checkboxes would be in a form like so: Code: <form action="" method="post"> <input type="checkbox" name="checked[]" value="1"> <input type="checkbox" name="checked[]" value="2"> <input type="checkbox" name="checked[]" value="3"> <input type="checkbox" name="checked[]" value="4"> </form> I use an event handler to call a function: Code: <input type="checkbox" name="checkall" onchange="checkall('checked[]', this.checked)">
And here is the function: Code: function checkall(box_name, current_state) {
all = document.getElementsByName(box_name);
action = (current_state == "checked") ? "false" : "true";
for (i = 0; i < all.length; i++) {
all[i].checked=action;
}
}
The event handler should pass the name of the checkboxes and whether the "check all" checkbox is currently checked or not to the checkall() function. Nothing happens when I check/uncheck the "check all" function. Help? from a browser address bar command? say if a page has hundreds of checkboxes, and I needed to check them all, but only 2-3 should be left out, how do i input a browser command line, to check it all, so i will manually uncheck the 2 or 3 thats not needed?
