To cut down on the user having to scroll through all 400 options I have included a text control that acts as a "Quick Index" and with each char entered into the text box the options are narowed. The problem I am having isthe once I have determined which option should be selected, how to set the option to value of "selected"
View 3 RepliesI am asking jQuery to tell me which drop down option is selected in a drop down list - like this:
I would like to check if this was successful before I proceed. What are the possible return values for this statement?
If no id exists.
If no option is selected.
If some other problem occurred.
In these cases am I expecting a null return; an undefined return, a false return value?
And, based upon the complete set of return possibilities, what would be the best and most comprehensive tests I could apply to cover every base.
I am having trouble getting the selected option in a list of more than 20 items in sharepoint, The code below works for lists of 20 or less but not for lists of greater than 20. If any one has a snipet of code that will enable me to set a variable with the selected value from a complex dropdown it

I have a javascript adding new options to a drop down select menu getting the information from the database.[code]...
I want one of them to be added as selected. I will put an "if" check and if it the value of the option and the value in the database is equal I want that option to be added as "selected".
I tried using the following code to check if the user has selected a particular option in a single select drop down has been selected, then add a class to a div to display it but it's not working and I can't figure out why. I've tried a ton of other things to but this one seems to make the most sense.
if ($("#existing-subscriber option[value='Yes']").attr('select')) {
$(".information").toggleClass("show");
}

How to find out the previously selected option value in a select list?
For example: I have a list with 3 options
<select id="test">
<option value="1">Option 1</option>
<option value="2">Option 2</option>
<option value="3">Option 3</option>
</select>
When user select, for example, option 3, how can i find which was the previously selected option? etc... I've found some javascript example that evaluate "previousIndex" property of the select element but it doesn't work at all
I am trying to display a rel of each option as they are selected into a div below it . There are several selects of classProductAvailability on the page. When one of the selects changes, I'd like the value of the rel of the selected option to display.At first it seems to work, but only if you start by changing the last pull down menu. The trouble seems to be in the"select.ProductAvailability option:selected", this needs to be written for this instance, not all of the selects of that class on the page. How do I write that, I've tried$(this+" option:selected") but it won't take.
<head>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.5/jquery.min.js"></script>

<select id="price">
<option value="">Please select</option>
<!-- show this if volvo -->
<optgroup id="vol">
<option value="30000">30000</option>
<option value="31000">31000</option>
</optgroup>
<!-- show this if audi -->

if I have a select with more options,
how I can know if is there an option selected;
is necessary a cycle? or is there an inner property?
I have a little bit of a complex script where I have a <SELECT> that is pre-loaded with options that are loaded from a database in PHP. But, when this page is loaded the <SELECT> is disabled, and is only enabled when an onChange() is triggered on another <SELECT> that is situated on the same page.
Anyway, when I enable the <SELECT> I would like to have one of the <OPTION>'s selected (instead of having a blank <SELECT>).
The line of JavaScript that I have so far (but isn't really getting me anywhere) to try to select an <OPTION> when the <SELECT> is enabled is as follows...
document.forms['edit_consultant'].elements[con_elements[j]].options[selectedIndex].value = consultants[conid][j];
..where I am guessing that the 'options[selectedIndex].value' will select the <OPTION> with the value of consultants[conid][j] to be selected.
I have a drop down with approx. 200 <option> elements, each option element has a value such as value="1", value="23", etc. Given a list of values, such as 5, 34, 43, 68, 123, how can pass those values to a function and then insert selected for each corresponding element?
View 2 Replies View RelatedI'm assuming it's possible to change the selected option of SELECT box with JavaScript based on the value and not index, but my searches have turned up nothing that seem to address this. It may be my searching terms, but if someone knows how to do this, could you post some code samples?

I want to use a <select> drop-down in a form to let my user select a date from a list. The problem is how to easily update the list.
Easiest would be to have a list of dates in a separate file, and have code that would read the dates and write them into the <option> statements of the <select> control. Then when the page with the <select> control opens, the code will open the other file, get the dates, and update the <option>s. And all I have to do is periodically FTP a new date file.
I'm stuck in Visual Basic and FileSystemObject, where I can open a file, read line by line into an array, concatenate a string, and write it into a doc. I can't seem to find similar methods in JavaScript - no duh, because this isn't VB!
So _is_ there a way to do this? Maybe a certain way to create the date file so the code can easily find the values? (Like putting the dates into a table with each <TD> having a unique ID?) And assuming I manage to get the dates, I need to write them into the source HTML, vice in the document body.
What objects, methods, properties do I look at? Are there any samples floating around out there?
cna anyone tell me how to use the Select = "selected" option for a simple dropdown. for example when someone chooses c it will have a code like <option selected="">c</option> (am I doing it right, well if you got a firebug some site with dropdowns offers that option) so can anyone tell me how that works. I will be using it for a purpose of just selecting parts on my array, well incorporating it
