JavaScript - Checkboxes With Results Logged

Checkboxes With Results Logged	View Content

Hi everyone,

I only know basic programing and was hoping someone can give me a hand with implementing checkboxes. What I'm hoping to achieve is a form that will have a number of checkboxes that, when a box is checked, the text corresponding to said box will be logged at the bottom of the page. Each checkbox will also have a numerical value which will display the tally at the bottom.

for example, I might have the following two boxes

Box 1: I have a Bike +3
box 2: I have a Car +5

When both boxes are checked, the log at the bottom would read:

I have a Bike +3
I have a Car +5
Total = +8

Code:

<form action="">
<input type="checkbox" name="vehicle" value="Bike" /> I have a bike +3<br />
<input type="checkbox" name="vehicle" value="Car" /> I have a car +5
</form>

Filter Search Results By Clicking Checkboxes

Similar Tutorials

Hey there everyone.

I'm a bit of a newb with javascript and php so apologies if this question is a bit simple, although I can't get my head round how to go about doing it.

I have a search page where a user can type in a search box, or they can use an alphabetical list to search for the record they're looking for. Eg they click 'a' and all the records beginning with the letter 'a' appear.

I'd also like to have it so that each record has a number of tags, and I'd then like to be able to filter records according to which tags have been selected - preferably using checkboxes.

For example, perhaps the tags would be colours and the records represented shoes. There'd be checkboxes for blue, yellow, black, brown and so on. At first all colours would be shown, but if the user clicks on brown the all but the brown shoes dissappear.

like I say, I'm new to learning php so please be gentle. Also I'm using Cakephp so if there's anyway to make it easier using Cake then I'd love to know.

thanks

Only Allow 25 Checkboxes

Similar Tutorials

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!

Need Help With Checkboxes

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.

Help With Checkboxes

Similar Tutorials

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';

  if(a3==true)
  {
    document.getElementById("crmForm_answer3_value").parentNode.parentNode.style.display = 'block';
  }

  else
    document.getElementById("crmForm_answer3_value").parentNode.parentNode.style.display = 'none';

Checkboxes.

Similar Tutorials

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

Help - Can't Figure Out How To Get Results To Write Into "results" Box

Similar Tutorials

Hi! I have been working on an assignment, and I seem to have things working okay, except that I'd like for the results (Message + list of 3 favorite movies or books) to show up in the Results box of the original page, not in a separate page. I'm sure it's something totally obvious that I'm missing, but I'm a newbie, and would appreciate any hints or tips that you all could give me.

Thanks so much in advance!

Check All Checkboxes

Similar Tutorials

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?

Cycling Through Checkboxes

Similar Tutorials

Hi Guys,

I'm currently working on a page working with separate categories and a whole lotta check boxes. My objective is to have one checkbox deselect the other checkboxes in its category without interfering with the rest. How would I go about doing this assuming the id tag is already in use and differs per tag? I was thinking about cycling through all checkbox tags and sorting them out via class but I'm looking for something possibly more efficient.

Select All Checkboxes!!? Help!

Similar Tutorials

Hello,

I have a form generated by mySQL and PHP, and inside the form (named 'UpdateDB') each line has checkboxes, like so:

Code:

<input type="checkbox" name="checkbox[]" value="96" onclick="highlight(this,'check_96')">

The onclick is to highlight the row, that works fine. However, I wrote a javascript function that toggles the select all the checkboxes or none. This is done by an image:

Code:

<img src="img/select.png" align="top">
<a href="#" onClick="togBox('updateDB');"><img src="img/all.png" name="listToggle" align="top"></a>

Easy, right? So heres the Javascript function that the above image (the 'none' part) links to:

Code:

function togBox(form) 
	{	var myForm = document.forms[form];
		document.listToggle.src=='http://gospeltruth.tv/admin/img/all.png' ? toggle = true : toggle = false;
		(toggle) ? document.listToggle.src='img/none.png' : document.listToggle.src='img/all.png';
		for( var i=0; i < myForm.length; i++ ) 
		{ 
			(toggle) ? myForm.elements[i].checked = 'checked' : myForm.elements[i].checked = '';
		}
	}

Its a brilliant function if I do say so myself, and this is what I dont get: two days ago, it was working fine, today, its not working at all. The image changes, but IE flags up the 'myForm.length' as an error.

How was it working 2 days ago and not today, when I havent touched it? Can anybody advise why its not currently working?

Thanks for your help,

Autosum W/out Checkboxes

Similar Tutorials

This script works via "elem.checked" which is great for checkboxes (see http://javascript.internet.com/forms...heckboxes.html), but I need it to work with image buttons instead where there is no "checking" going on. Is this possible?

I tried elem.onclick and elem.clicked but neither works. I don't know enough about onclick conditionals. Please help.

Code:

function UpdateCost() {
  var sum = 0;
  var gn, elem;
  for (i=0; i<4; i++) {
    gn = 'game'+i;
    elem = document.getElementById(gn);
    if (elem.checked == true) { sum += Number(elem.value); }
  }
  document.getElementById('totalcost').value = sum.toFixed(2);
}

tl;dr: Want to make the above work with <a onclick="UpdateCost()"><img></a>, not <input type="checkbox" onclick="UpdateCost()">

Checkboxes Question

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
