Is there any way to enable a form element(s) based on the selection in a <select> drop-down? I'm trying to enable/disable a group of checkboxes depending on which option is chosen in the <select> above it.I know how to enable/disable something when a box is checked (or text is entered into it) but I have no clue how to handle the <select> option.

I have a select box where the value must be passed via the form. If the users selects choice B or Choice C then I want a specific div to show. If they choose choice A then I want the div to hide or remain hidden. It should be hidden on page load.

Ok so I have a select box where the value must be passed via the form. If the users selects choice B or Choice C then I want a specific div to show. If they choose choice A then I want the div to hide or remain hidden. It should be hidden on page load.
<select name="Event_Type_ID">
<option value="1">Choice A</option>
<option value="2">Choice B</option>

disable select until user puts mark in check box. Then enable select.I have two select box's on a page. The first asks what product, the second is based on the first and presents a list of pdf's according to which product the user selected. (yes, multi dimensional)What I have works fine, but now i need to make the user put a check mark in a check box before the First SELECT box becomes enabled/available.So basically, when they agree, they can get the download.Here are my select boxes.
HTML Code:
<form>
<select name="category" style="width:180px"></select>
<select name="site" style="width:180px" onchange="openLink(this.value)"></select>[code]....
(ignore the The 'open' button. It's there in case the default option is what the user wants, so they don't have reselect via the select box.)
1. How do I disable the select boxes by default on page load?
2. How do I detect that the user has put a tick in and the enable the disabled Select box?
I have searched and found lots on enabling/disabling form inputs, but nothing that matches my needs.
I have a form with a dropdown with values 0-4. If value 0 is selected I want the checkboxes to be disabled. If value 1-4 is selected I want the checkboxes to be enabled.
Code:
<html>
<head><title>Disable with Dropdown Test</title>
<script>
function num_check(sel,cb) {
[Code]....
Would anyone care to post your favorite script for disabling the submit button on a form when there are input errors, and reenabling when all errors are resolved? I'd be curious what the different approaches are to this. I looked through my various SitePoint javascript books and surprisingly didn't find an answer to this scenario specifically.The behavior I'm trying to achieve (most efficiently) is having a form start out with the submit button enabled, but if there is a validation error, such as a required field being left blank on blur, the submit button is disabled. It's easy then to re-enable it when the user fills in that field, but harder to get the script to check and see if there are any other lingering errors before going ahead and enabling it.
My natural inclination would be to just keep a count of errors that increments and decrements when errors occur and are resolved. Then the script would check to see that the error count is 0 before re-enabling the submit button. It seemed easy, but I think I'm getting mixed up somewhere in conflicts of variable scope, and it's not turning out right.A google search rendered an example where someone was using a string variable to store errors, concatenating and replacing data to the string as errors were logged/resolved.
I've this code:
function checkdate(FormSubmit){
alert(document.getElementById('Mois').value);
if(eval(document.getElementById('Mois'))>0 &&
eval(document.getElementById('Annee'))>0){
document.forms['FormSubmit'].getElementByID('SELECTCONSTRUCTOR').disabled
= false; //can't reach the control here
}
else
{
document.forms['FormSubmit'].getElementByID('SELECTCONSTRUCTOR').disabled
= true; //can't reach the control here
}
}
....
<form name="FormSubmit" method="post" action="">
....
<select name="Mois" onChange=checkdate(this.form);>
....
<select name="Annee" onChange=checkdate(this.form);>
....
<select name="SELECTCONSTRUCTOR" disabled>
Now, what I would like, is to enable the SELECTCONSTRUCTOR if month and year
are selected (I mean different to 0).
I can't enable or disable. In fact I can't reach the control in the
checkdate function...
How can I enable/disable SELECTCONSTRUCTOR when my 2 fields are selected?
I have 2 text boxes I want to control with a select.
I can code this problem myself, but was wondering if there is some better way to do it...
There are 4 values for the select, "", S, R, and B.
When "" is selected I want both boxes to be disabled, When S or R are selected the Stext or Rtext will be enabled respectively When B is selected both will be selected...
So I have the function to handle this in my own custom UI namespace.. Here is the function:
SRB: function() {
if ($("#SRB).val() == "B") {
// enable both boxes
} else if ($("#SRB").val() == "S") {
[Code]....
etc.. i guess you get the picture. Basically the question is, is there a way to do this without statically setting if conditions for each select box condition?
I need to be able to uncheck and disable a checkbox based on the option selected in a Select list.
This is what I tried.
==============
<script type="text/javascript">
function GetOptVal(OptVal)
var OptVal;
{
if(OptVal="XX") document.form1.chkbox1.disabled = false;
}
else
{
document.form1.chkbox1.checked = false;
document.form1.chkbox1.disabled = true;
}
</script>
<form name="form1">
<select name="Opt1"
onchange=GetOptVal(document.form1.Opt1[document.form1.Opt1.selectedIndex].value)>
<option value=" ">Select One</option>
<option value="XX">XX</option>
<option value="YY">YY</option>
<option value="ZZ">ZZ</option>
</select>
<input type="checkbox" name="chkbox1" />
</form>
Firebug returns an error saying msg.elements is undefined. I'm trying to make a function that will enabled a delete button if any of the check boxes in a list are checked.
Code:
function selectone () {
var msg = document.getElementsByName('pm');
var i = 0;
for(i; i < msg.elements.length; i++)

I am working on a little project here. I have two arrays (States, Cities) I am trying to allow the user to chose one from a select form (Choice) and then have the values of the chosen array displayed in a alert(). Obviously I could just write an if statement and display the required content depending on whether the value selected == States or Cities. But this project is just a placeholder project for me to figure out one aspect of a much larger project I am working on. And it is important for the result to be chosen dynamically as in the final project I won't know the values that the select field is being filled with.
What I need to do is take the value returned from the select field (Choice) and turn that into the name of the array and display that. If I use this code alert(States); then it returns the values of that array. But like I said I need to be able to dynamically select what array to display based on users input.
alert(document.getElementById("Choice").value); returns the value chosen. How can I take the value chosen and actually display the value of the array with that same name. In other words let JS know that I don't literally want it to display the value chosen but rather the value chosen is the name of the array I want it to display?
Pseudo code
x = document.getElementById("Choice").value;
x is name of array;
alert(x);

I have a checkbox at the top of the page, and then I have a form full of text fields etc, called 'frmEnquiry'.
I would like the form to be disabled (or the text fields, elements etc) when the checkbox is not enabled, and when ticked i would like it to be enabled.
Is there a function or way round this?
based on selection of radio button, i want to change the text box to enable and disable. And additionally, how to set if i enter a value in textbox1 then calculating something and display the result in textbox2 that to on key up.. not on form submitting.
View 4 Replies View RelatedI have multiple forms on my website. Some of them have a checkbox which is checked by default, whereas others are unchecked by default. I'm trying to figure out how I would detect whether or not the checkbox is checked, and if it is checked, disable certain fields (not necessarily all fields), and then toggle it back and forth as I check or uncheck the box..I found this code:
Code:
<script language="javascript">

What I want to do is: disable the submit button while not all form fields are filled out and eneble it when the form fields are filled out. Disabling works, the enabling doesn't, at least not 'automaticly'. All of the code is in the $(document).ready(function(){}
I have this code:
checkAll();
function checkAll()

The website I'm currently developing has a search area where users can narrow down where or what service they would like to view.The problem I'm having is, I have certain things that fall into only certain areas.Here is the actual form:http://www.xgfx.co.uk/drop-downs.jpgAnd this is the code behind it:
<form id="ticsearch" action="searchtic.php">
<select name="country">
<option value="1">Select Country...</option>

I have a form with a dropdown and input field:
<form1>
<select name="warranty" id="warranty" onChange="doadate()">
<option value="Select">Select</option>
<option value="In Warranty">In Warranty</option>
[Code]....
But it's not working, it stays disabled after load even when the DOA is selected in the dropdown form field.
I have an array of list boxes. I need them to become disabled if the first one is checked (with an id of disabler_0), and I need them to be enabled if that box is unchecked. Right now it doesn't work.

I have a message system that I want to prevent double posting. So when a user sends a message i would like to disable the button. But its done using AJAX and will load without much time. But enough to cause double clicking. So now the button needs to be enabled once Text is put in the Form Field.
View 2 Replies View RelatedI have a web form that I'm creating and it has some expandable checkboxes that need to be restricted based on choice.
This is my criteria:
If someone chooses checkbox number 1, they cannot choose any other checkbox.
If someone chooses checkbox number 2, they may also choose number 3 but not 1 or 4, they must also answer the question that appears below.
If someone chooses checkbox number 3, they may also choose number 2 but not 1 or 4, they must also answer the question that appears below.
If someone chooses checkbox number 4, they cannot choose any other checkbox, and must answer the questions that appears below.
One more caveat: If checkbox number 2 is chosen, and they've filled in all three lines of the question below, I need for them to dynamically add more lines as needed.
I have attached my web form so you can see what I've done. I've researched these options and tried code from various examples but I can't seem to get it to work.
I am facing an issue where a link on my website opens in a new window if you simply click on it. However, if you right click and say open in new window or new tab, it opens the same window (URL) again from where the link is clicked.
Self Service Option is a link and the JSP calls a function getSelfServSite() when the link is clicked. This is how the code flows in my case
function getSelfServSite()
{
getToTheLink("${myConfigInfo.selfServiceURL}");
// this is because the URL is configurable
[Code].....
I want it to go to the right link no matter how the user click it.
I have spent the last 6 hours working on this, and I am about to lose my sanity. I need your help very desparately. I want to create some radio buttons for building a computer for a class project. Basically, what I have now is the radio buttons in separate groups, and a function that calculates the total price of the items selected. But what I am finding impossible to get is this: I need to set it up such as that if you select a radio button in one group, it disables part of the second. What this means in my work, is that say I choose AM3 as the CPU socket, only AM3 motherboards and processors will be enabled, and the rest in these categories will be disabled.
I am trying to set it up in a way that when you first open the page, cpu, motherboard and ram groups all disabled, then based on your socket choice you get different options for motherboards and processors, and then based on your motherboard choice you get different choices for RAM.
I'm trying to make a function that will disable elements of a form based on which options are selected.
I have made this work for individual form controls but now i want to make it into a function that could be used on any form control.
Here is the broken function
Code:
I've probably just missed something but i really cant see what?
What I would like to do is have a page with a dropdown menu, and depending on which option the user chooses from the dropdown, reload the page and display a particular iframe below the dropdown, based on the users choice. Also, a default iframe would load (the one connected to the default choice in the select box). I was trying to make this work with PHP (without having the user having to click a submit button) but I couldn't find a way to make it happen.
View 6 Replies View RelatedHow does one cause a form element to appear ONLY if a certain form selection is made before it?
That is for example say there is a form element of type Radio called "format" so only if they select format value = normal then the form input fields called URL and Name are to appear as the next choices otherwise form input field Group and checklist Places are to appear as the next choices.
