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 :: 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.

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.

How To Pull A Value From A <select> Control

Sep 22, 2011

I would like to pull the displayed value from a select control, here is an example:

<select id="test" name="test" size="1">
<option value="1">Yes</option>
<option value="0">No</option>
</select>

I'd like Javascript to grab the Yes or No of the select, not the 1 or 0. So, for simplicity, lets use an alert: alert(document.getElementById("test").value) That produces the alert box with 1, I'd like it to alert saying Yes.

Control Collection In Javascript

Jul 23, 2005

I have a .net application that I am trying to add some javascript code
to for a client-side execution. What I want to do is resize all the
HTML text fields on my web form, but instead of writing a line for
each text box I would like to loop through a collection of controls
and resize the control if it is a text field. Is there a way to do
this in javascript? The function below is what I have been toying with
for the past couple of hours. Another idea was to use a css, but I
can't find an element for the text field.


function Test()
{
Tarray = new Object;
Tarray = document.Form1.children
for (var prop in Tarray)
{
//document.writeln(Tarray.toString);
var s;
s = prop
if (Left(s, 3) == "btn")
{
prop.height = "20px";
}
}
}

JQuery :: Selecting <SELECT> Next To <INPUT> In A Control Array?

Aug 21, 2011

I have a series of TEXT inputs each with a corresponding SELECT next to it. I don't know the actual ID of these controls because .net assigns them, but I can use a wildcard.

When the focus leaves one of the Text inputs, I want to display the corresponding Select (which is previously hidden). My ready function looks like this:

Using Javascript To Control Acrobat Reader

Mar 28, 2006

I need information (sure, i used google but couldn't find anything useful yet) about automating/adjusting Acrobat Reader using javascript. I need to print multiple documents without having to open them individually and selecting the print option on each document. I also need to adjust the user interface. Sometimes printing is allowed, sometimes it is not. So i need a way to disable (or remove) the print button from the default toolbar.

Anyone has experience (sample code) or documentation i can use?

Control Printing (What Prints) With Javascript ?

Jul 9, 2004

When designing a site, a request has come to me about printing web pages. What they want is the page to be broken up into frames, and only one frame will be able to be printed. so that if the page is broken into 3 vertical frames. Would it be possible to have it only print the middle page if the person clicked the print button.

This is so that even beginner users to IE or Netscrape would be able to get a printout of the page without having to change options in the print preferences.

* The example the person gave me was similar to Page Breaks in MS Excel. You can see the whole thing, but when print is clicked, you only get a certain section printing (even a beginner can do this).

Javascript Control For HTML Radio Button

Mar 24, 2006

I'm not what you would call naturally gifted with javascript (I use PHP mostly), so I hope this is an easy question for one of you....

I'm trying to create a HTML link that, when clicked, affects a pair of HTML radio buttons by moving the selection from one radio button to the other.

the following code is wrong, but It's all mine, and its what I've written in a feeble attempt to accomplish this:

<HTML>
<HEAD>
<TITLE></TITLE>

<script type='text/javascript'>
<!--
function rejectAll()
{
if (window.document.link_form.a0.checked == 1)
{
window.document.link_form.a0.checked = -1;
}
}
-->
</script>
</HEAD>
<BODY>
<form action='file.php' method='post' name='link_form'>
<input type='radio' name='a0' value=&#391;' checked>
<input type='radio' name='a0' value='-1'>
</form>
<a href='javascript: void(0)' onClick='rejectAll();'>Reject All</a>
</BODY>
</HTML>

Can anyone see what I'm trying to do here and point me in the right direction...
