Dynamic Validation - Checkbox Checked On Submission?
Jan 10, 2011
I have an HTML table with <tr> sections that is generated by php which looks like the following
HTML Code:
<tr align='center' class='row_a'>
<td align='center'><input id = 'assign0' type='checkbox' name='agent_8949' value='0' /></td></tr>
<tr align='center' class='row_b'>
<td align='center'><input id = 'assign1' type='checkbox' name='agent_8950' value='1' /></td></tr>
<tr align='center' class='row_a'>
<td align='center'><input id = 'assign2' type='checkbox' name='agent_8951' value='2' /></td></tr>
<tr align='center' class='row_b'>
<td align='center'><input id = 'assign3' type='checkbox' name='agent_8952' value='3' /></td></tr>
The id's and values are generated by php, my problem is, I want to use javascript to check if anyone of the check boxes has been checked on submission meaning that I have to go through the <tr> list. Here is my JS code which only works for one id.
Code:
//I know the length of the checkbox (checkBoxID) fields which is the number of rows in the database table
function validate(checkBoxID){
var ids_Prefix = 'assign';//we know all the ids starts with this string
for (var i = 0; i < checkBoxID; ++i) {
if(document.getElementById(id_Prefix+i).checked == false){//how do I check the next one?
alert("You did not make any selection");
return false;
}}}
I have a fairly straightforward form with validation on a number of fields, all of which is working fine.
I have credit card information fields being validated only if a Payment Method radio button is set to 'Visa' or 'Mastercard', and this is also working correctly.
These input names don't appear anywhere else in the HTML document and they're not validated fields, however if either of them are checked, the conditional credit card validation no longer fires, although the remaining non-conditional validation on the page continues to work as normal.
EDIT: It would appear that if *any* of the radio buttons on the form are selected, the payment information validation is disabled.
I'm at a loss as to explain what's happening. I'm leaning towardsinput[#payment_method]:checked syntax, and specifically the :checked syntax as potentially causing the issue
I have a form which contains a number of check boxes in format of fielduse_x where x is incremented each time (1 - 30)
Everytime one of the checkboxes is ticked or unticked i want to perform a function for related boxes but i am having difficaulty doing this.
The code i have in the javascript is :
function changeStatus(f) { alert(f); if(document.newForm.fielduse_[f].checked==true) alert("YES") else alert("NO"); }
f is passed from the form field and contains the number (1 - 30). I know that the form is passing the values across as alert(f) gives the correct number. I don't seem to be able to get the next line to work. How do i put the value of f into the if statment as what i have done isn't working
I'm trying to create a form whose onsubmit returns false if the form should not be submitted. Normally this type of thing works great for me:
<form onsubmit="return somefunction()">
where somefunction returns false. But I'm trying to do some thing where in some script block, the function gets added:
form.attachEvent("onsubmit", function () { return somefunction() });
(not worrying about crossplatformosity, sorry). But that doesn't work, the form is always submitted. Is there something else I need to be doing to make this happen?
Assume there's a form with it's action attribute all set to post to a URL, but without a submit control. Form submission is done via a link and I want to prevent the classic "double submit". Ignoring the server side of things, does anyone see any holes with the following script? It seems to work, but I'd appreciate other eyes on it. Maybe a try/catch/finally wrapper of some sort to be sure the link is re-enabled in the face of an exception. I understand there are (many) other ways to do this (e.g. temporarily "remove" the link), but I'm mostly curious about the this.onclick=falseFn/this.onclick=arguments.callee combo and any potential gotchas....
When you press the subscribe button (beside RSS), a form drop down (which is initially hidden), and it is then validated (for email) and once submitted replaced with a thank you message. I need to duplicate this.
I am having a problem with the last results. I can't seem to be able to get the input2A and input3A to appear. I don't seem to have a problem with the show and hide after a number is entered and submitted. If anyone can answer my problem I will be greatly appreciated with a prize. I actually have submitted it more than once and I haven't had anyone been able to answer it yet. Code:
I have a form and trying to validate all fields with jquery validation plugin.Every thing is fine except the checkboxes which i create dynamically.[code]how i make a rule which check that if no check box is checked then show error message like above input fileds do.
I'm trying to dynamically create a checkbox element with the checked status being true however it never works in IE, I've tried everything I can think of. The code works in firefox but IE never checks the box, when I do an alert it says its checked but it does not render the check.
i am checking the checkbox is checked r not by using following code.... if the condition is true i have to checked another box in runtime using docuemnt.form... or document.getElementById like...document.form.chkbox2=checked like that...
I have a checkbox and when the it's checked I want to increase the row of the textarea
for(i=0; i < chkBoxes.length; i++) { chkBoxes[i].onclick=function() { document.getElementById('addnote').rows =4; // this only increase the textarea of the first row. If I have more than row , it won't work }
I have a checkbox in a form. The form is submitted via ajax everytime a users makes any chenges to the drop down menu's in it and returns an updated value. That part is fine. the part I'm having issues with is the checkbox in the form. Initially it is set to checked. The proble I have is that when the ajax script runs it takes the value from the checkbox regardless of whether it is checked or not!
How can I get around this? Is there a way to set an initial value and another checked valus on the checkbox? I've had a look and can't find anyway to do this.
Complete javascript idiot here. I'm not looking for code, but just an explanation of how difficult this would be to implement, and maybe some resources that could help me code this/alter existing open source code.
Basically, I want to put a cookie in a user's browser if they visit page A. If they then visited page B (which has a form on it) in the next 3 months and submit the form, a hidden checkbox will be set to "checked."
function showBoxes() { var sum = "You have selected: ";[code].....

I am using 2-3 checkboxes in my VB.Net program.When I run the code in Firefox, I can not check or uncheck the checkboxes.I am using firebug,Still it does not show any error. It works fine in google Chrome..
I have a survey/form for people to fill out. It has 3 sections. The first question has 3 checkboxes asking which of the 3 events the person attended. I want to hide the 3 sections of the form and then when the user checks the box sayign he/she attended certain events, to then show those sections of the form.
I've added some functionality to a checkbox. So that when the checkbox is checked it will display a div, when unchecked it will hide the div. This is working fine except when the checkbox is clicked, it doesn't display the checkmark in it. And when the form is submitted, the checkbox is unchecked.
Basically, at the moment I have 2 fields, the billing address and the shipping address.How it works at the moment is that when the user clicks the checkbox, then the details are copied across.I don't want this, basically I want it so IF the checkbox is ALREADY checked, then dynamically copy across the details, whether its on an onKeyUp or whatever.Code is below .
javascript:
Code:
function eCart_copyBillingToShipping(cb){ if(cb.checked){ // Only copy when the checkbox is checked. var theForm = cb.form;[code].............
