Script Validation Of Html Select/option Tag?

Mar 23, 2011

I have a form and I have gotten all of my error checking to work except for this. I use an <select><option> list for a states dropdown. the 1st option is blank <option></option> I have not been able to successfully check for errors (no option selected) it either always gives and error using if(state==null), or never gives an error state=="" or " " this is the only dropdown on this form so I didnt notice the problem until I had gone through all the more difficult error checking, and somehow I cant get this one seemingly simple thing figured out

Javascript Option/Select Box Validation?

May 29, 2002

Is it possible to check an option/select box to see if it still has data in it? I'd like to be able to stop a user from updating a file IF the field they are copying from still has content in it. I.e.

BOX 1 BOX 2
1 3
4
6
2
5

So the button will display an error message (e.g. you aint sent the entire lot over)

I've tried to attempt it but my mind cannot really handle anything more than (Check kettle for water, IF water equal or less than 1 cup full, then fill kettle with water, If kettle equal to or greater than 3 then STOP).

JQuery :: HTML Select Add Option Does Not Work In Firefox

May 20, 2009

I am trying to add select items via jquery to a select control. The following code works perfectly in IE, Opera. Chrome and Safari, but for the life of me I cant get it working in firefox. I really don't think its a bug but I must be missing something obvious.

<html><head>
<script type="text/javascript" src="../lib/jquery/js/jquery-1.3.2.min.js"></script>
<script type="text/javascript" src="../lib/jquery/js/jquery.selectboxes.pack.js"></script>
<script type="text/javascript">
$(document).ready(function() {
PopulateSelect();
});
function PopulateSelect(){
$("#s1").removeOption(/./);
$("#s1").addOption("Value1", "Text1");
$("#s1").addOption("Value2", "Text2");
};
</script></head><body>
<select name="s1" id="s1" onchange=""> </select>
<input type="button" name="button" id="button" value="Button" onClick="javascript:PopulateSelect()">
</body></html>

JQuery :: Removing An Option From A Select Based On The Option Value?

Jun 21, 2010

I'm using the following code to remove an option from a select control based on a selection in a different select control and the option text in the select option that is being removed. The code works as I want it to, but I would prefer to use the option value for identifying the option to remove instead of using the option text. I've tried several different ways to do this, but can not find the proper syntax.

Removing Select Option Removes Entire Select

Jun 21, 2006

I'm using Prototype and scriptaculous either, but here it is:

I have two select areas and scripts to transfer items between the two.
Everything works great in FF, but in IE when an option gets removed it
removes the entire select area. Has anyone ever seen something like
this before?

JQuery :: Select Dynamically An Option In A Dropdown Select?

Aug 11, 2010

According to [URL] intended way for jQuery to change dynamically the selected option of a dropdown select control isassigningthe desired text instead of the value. I found this way veryinconvenient (data structures usually deal with value codes, not value descriptions) and it seems to work only sometimes.

Trying different options I came out with this approach that seems to do the job so
far:

function setSelect(pID,pSelectedValue)
{
$('#'+pID + ' option:selected').removeAttr('selected');

JQuery :: Create An "Add New Option" Option To A Select List?

Oct 12, 2009

I have a form that uses jeditable to edit-in-place several fields and select boxes. Everything is working great. Now I need to a way to add a new option to the select list. What I would like is the user select "Add New..." from the select list that would pop-up a dialog window where several fields are filled in. When the form is saved the select field is updated with the new ID and description. I use Facebox for pop-up windows to display notes when the user clicks on a topic. I know Facebox can be used to display a form. It would be ideal to use this ability when creating a new option for the select box.

Jun 30, 2007

I am having a problem with a simple javascript validation routine for a drop-down list, which works fine when there is only one form on the web page, but breaks when another form is added. I am new to javascript, so I expect this is a simple error in syntax.

JQuery :: Option To Not Defer Required Validation?

I have a form that displays data from a database table, and makes some of the fields text boxes, so the user can edit them. These text boxes are required fields. But if the user deletes the text and then tabs out of it, the "required" error message does not come up, until some other validation is done or the form is submitted.

Form Validation & HTML W3C Validation?

Feb 21, 2010

I have my website www.gebcn.com. If you view source you will see all that I have done, but more importantly my problem. I have the JS code at the top there and I am unable to W3C validate my HTML because of the JS. I am using XHTML strict and would like to stay using it.

The JS I have at the top is my form validation code. I am able to do any validating that I need with this "snippet" of code, I have shrank it from my library version just to use for this newsletter. Until now W3C validating was not important now for some reason it is and I am faced with this problem.

I am not a Javascript guy more of a HTML/CSS guy and I can manipulate JS to suit my needs.

<problem> I have tried to make this "snippet" of JS code an external file but receive multiple errors with the JS calling for the FORM NAME as it is not on the same page. The form NAME=NEWSLETTER is another problem, as W3C says I am unable to use attribute "NAME" in this location. <problem> I would like to keep the JS close to how it is now as I have a library to use this JS over and over again.

Form - Set The Validation So If One Option Is Selected From A Picklist - Complete A Text Field As Well

Feb 14, 2011

I have a form set up and I need to set the validation so if one option is selected from a picklist, they need to complete a text field as well.

This is the code i'm using:

Code:

Reason is a picklist, I want it to show the alert when option 1 from the picklist is selected and no text is in the Row_Number field.

If any of the other options are selected, I want to make sure the Row_Number field is blank.

As I said, I'm sure this is a very simple thing, but I been working on it for ages, and cannot get it to work, I get the alert every time the Row_Number field is blank.

JS To Select An Option In A Combo Box

Jul 23, 2005

How do i select an option in a combo box? i have tried looking on the internet but dont really know what i should be searching for. what i want to happen is that when a function is called
a line of code will select a specific option in a combo box. something like:

//excuse the dodgy syntax

function select_combo() {
cb_1.select[3] //where option 3 will be selected (or 4 if first index
is 0)
}


the combo box would be something like:

<select>
<option>First</option>
<option>Second</option>
<option>Third</option>
</select>


The function would change the selection in the combo box.
