I want to add the + but stop when i reaches the checked length minus 1.
Code javascript:
var checkedlength=0;
for(i=0;i<document.getElementsByName('checkresult').length;++i){
if (document.getElementsByName('checkresult')[i].checked){
[Code]....
I realize that document.getElementsByName('checkresult').length in if(i<document.getElementsByName('checkresult').length-1) is not the same as the checked.
I have a form. It has several products. Each product has a price listed. Each product can be selected via a checkbox.
What I would like to do is have the sum of each selected product, added in total at the bottom of the form.
I would prefer to use javascript/dhtml for this, I don't want anything complex, just something to add to the page and have it display the total live as the customer checks/unchecks a product.
I am trying to figure out the best way to count how many checkboxes were selected. Suppose I have the following HTML:
Code:
<form name="myform" id="myformid">
<input type="checkbox" name="items[]" id="item0" value="One" />
<input type="checkbox" name="items[]" id="item1" value="Two" />
<input type="checkbox" name="items[]" id="item2" value="Three" />
[Code]....
But I don't think I can do it that way since I'm dumping it all into an array for processing.
I'm struggling to make a js alert when none of the 3 checkboxes on my form are selected.
function checkform ( form )
{
if (form.contact_name.value == "contact name") {
alert( "Please enter a contact name" );
[Code].....
This is what i have. It does not correctly add two values when two checkboxes are checked. It should add up to 160 but it adds up to 20 instead! any ideas?
[Code]...
how do you count the number of checkboxes that have been selected say I want more than 1 and less than 3 to be selected out of 5?
<script type="text/javascript">
if (document.formName.numberOfBlanks.checked >= 1 && document.formName.numberOfBlanks.checked <= 3)
alert("test")
[code]...
I have a form with checkboxes. I have the results being stored as an array, that gets sent to a mysql database.
how can i limit the number of checkboxes selected? I am looking for a max of 15 selections.
i've been able to set the max when the checkboxes are not stored as an array, but for simplicity storing as an array is the way i need to go.
I have used the following in retrieving selected checkboxes:
Now, I would like to post all of them (simultaneously) to a php file.
$.post('form.php', { /* How can I pass all selected checkboxes in one post method? */ });
I tried using arrays but unfortunately failed.
I have written the following script which enables/disables checkboxes on my page when a radio button is selected.[code] What I would like to do is create another function called checkval() like below, which will check the value of my radio button (id: email_alerts). If the value is equal to "on" then it will run enableCheckboxes().

I have the HTML all laid out for what I'm trying to do. I want to have the user be able to select any 10 checkboxes, and keep a tally of how many are selected, and how many are left to go. Should I do this with jQuery?
Code HTML4Strict:
Select any 10 cds for $20<br />
You have chosen $selected CD's<br />
You have $remaining CD's left</p>

like for example i have text areas named upload1 and upload2when I click or add input on upload1 a drop down list below upload2 will not change, but when I add input on upload2 the dropdown will select "parts"

View 2 Replies View RelatedThis is irritating cause i read a arcticle with a solution to this in one of the many newsletters i receive, but then i didn't need it and now i do i can't find it, and i'm searching for days now .
I have say 3 links
link1 --- link2 --- link3
all of then formatted nicelly with CSS. When i select one of then, say link1, it becames with a diferent background color.
What i want is to keep tha backg color even when the user clicks anywhere on the page (thus loosing focus) and until another link is clicked.
I tought this could be possible in a CSS only way, but now i think i have to use some Javascript.
I'm using jQuery to check if a group of radio buttons has one of them selected. This works fine if there IS one selected, but errors if NONE are selected. Can anyone show me how to make it work if NONE are selected?[code]
View 1 Replies View Relatedi need some creative input. i'm trying to enable the user to input a
length of time, from one day to about 10 years. ideas i've had have
been:
- 3 pull down boxes, for days, months, years
- an entry box for a value and a pull down box for units (days, weeks,
months, years)
- a scroll bar to slide along to a corresponding time
I'm not sure i should even use javascript, maybe an applet instead. I'd
really appreciated some new ideas or brainstorming.
I have a problem with getting the amount of childs in a XML structure,
the strucure is somewhat like the following:
<?xml version="1.0" encoding="iso-8859-1"?>
<cms>
<num>21</num>
<xmlnames>
<field>id</field>
<field>name</field>
<field>availablefrom</field>
<field>availableuntill</field>
<field>owner</field>
</xmlnames>
</cms>
If I use the following to get te amount of childs for xmlnames I get an
amount of 11:
xmlObj.responseXML.getElementsByTagName('xmlnames' )[0].childNodes.length
Is this wrong or maybe there is a better / other way of counting the
child amount?
I am running a bit of JS to highlight text inputs onFocus in IE. It
seems to be working on all of the forms on the site except one. The
debug code in the script displays the number of input elements in an
alert. On the page where it does not work, the alert is "[object]".
Here is the script:
function initHighlight() {
if (!document.getElementsByTagName){ return; }
var allfields = document.getElementsByTagName("input");
alert (allfields.length); // debug
for (var i=0; i<allfields.length; i++){
var field = allfields[i];
var attr = field.getAttribute("type");
if (attr == "text" || attr == "password") {
field.onfocus = function () {
this.className = 'highlightActiveField'
}
field.onblur = function () {this.className =
'highlightInactiveField'}
}
}
}
function addLoadEvent(func)
{
var oldonload = window.onload;
if (typeof window.onload != 'function'){ window.onload = func; }
else { window.onload = function() { oldonload(); func(); } }
}
var isIE = navigator.appName.indexOf("Microsoft") != -1;
if (isIE) { addLoadEvent(initHighlight); }
Unfortunately, I cannot reveal the URL of the page (contractural
restrictions).
Under what conditions would IE believe that the length of input fields
is an object, not a number? I have run the page through two
different validators and there are no errors.
I have a standard ul list where I need to keep count of the li's within (users can add/remove). This is my function when they remove a list item (.remove is inside the li), it removes the li fine but I always get zero for the rows.

I want to add some length validaitons to this form so that the state is enterted two characters long, the zip is entered five charaters long and the phone number will be entered eight characters long. Code:
View 2 Replies View RelatedThe following function takes three different fields (which combined make up a phone number) and tests it to make sure that all the characters entered are integers. If this is true, it sets form.Phone.value = entirephonenumber. I would like to incorporate an additional test which, after determining that all characters in the string are integers, checks to make sure that the string length is 10. If it is less than 10 or more, I want the entire function to return false and display an error message (the same one is fine..) Code:

I'm attempting to run some checks on an input value. Initial HTML:[code]After the page loads a javascript calendar function called JDPicker runs and changes it to:[code] my issue only occurs on this HTML that is hard coded into the page.

When I try to get the child elements value it gives me this error: "value null or is not an object". I tried using .nodeValue after that and it worked, but then started giving me errors regarding the .length function "length null or is not an object".
