I have a dropdown called "style". How can I use javascript to tell me what Item is currently selected? Here is what I currently have
Code:
var xx = document.getElementById('style').selected;
alert(xx);
When I run this, xx = "selected".
I 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've got 2 drop down select lists. The first one would have something like
-Category 1
-Category 2
-Category 3
Then what I'd like to happen is when you select one of those categories the next drop-down below it loads something like
--Sub Category 1
--Sub Category 2
--Sub Category 3
Any idea how I'd pull that off?
Could some one help me build a simple quick function to get the selected items in an HTML listbox and add them to a string var? I need to have the values seperated by "~"
View 2 Replies View RelatedI have a form for taking customer details. Part of the form will allow the user to select some upgrades for their selected product. The upgrades will be displayed in a drop down list with their additional cost. The total cost of the product being ordered will be displayed on the page.
Could someone please advise me on the best way to automatically update the total cost displayed on the page each time an upgrade is selected? I am using PHP for the site but I'm assuming that javascript is the best choice for this.
I have a multiple select list
<select id=mylist name=mylist[]>
<option id=1>first</option>
<option id=2>second</option>
<option id=3>third</option>
<option id=4>fourth</option>
<option id=5>fifth</option>
</select>
Then I have a string of id's that I want to set to selected like so.
var selectedIds = '1,3,5';
Is it possible to use jquery (preferably in a one liner) to set first, third and fifth to selected.?

I am a beginner with JavaScript. I have modified a script or two, but have no real JavaScript knowledge. Others with more knowledge than I have suggested that I check here.
I am building a website for my daughter. She wants to put up a list of items (groceries). The visitors would select the items they want to buy, and then print a shopping list. If there is an available online coupon, that may also be printed. There would be no need to remember the information after the visitor prints. I will be getting a JavaScript book(s) to teach myself something about the language, but for this project, I don't know where to start?
Do I need to have the items in a database, or just program a button in front of each item?
Do I need two different (or more) scripts? One to select items, one to display the items, and one to print (or use the browser print)?
I cann't get count the selected list box items using javascript.

i'm after some script to display some html depending on what is selected in a list box
the html i want to display are checkboxes so it's more stuff for a form i'm using lotus notes, so i have to use javascript.
i can get it to display a checkbox if a particular item is selected but it won't show up in place, it loads a new page with the check box the only thing on that new page.
function updateChecks()
{
string = "";
if (document._WEBRequest.dataReq.value == "blah") {
string = "<input type="checkbox" name="check" />";
string += "Boundary";
}
return string;
}
function writeChecks()
{
document.write(updateChecks());
}
the writeChecks() function is called onChange for the listbox
also don't have much clue as to how to make it show more checkboxes if more than one item is selected in the listbox.
I want to compare items based on what the user picks there will be 3 drop down menus and the drop down menus should alter the HTML table each time it is changed, giving different option values and stuff. I am wondering how to go about this I have the basic stuff setup but I am not really sure how to add to a table that all 3 options use.Here is my current code for the drop downs.
<form name="compare">
<select name="compare">
<option value="V1">Value 1</option>
[code]...
I want the user to select one of the options from above and a table to show up showing the differences between the others for example; someone selects Value 1 for compare, and Value 2 for compare 2, and Value 3 for Compare 3, they should be shown a table which has the differences between Value 1, Value 2, Value 3. So lets say Value 1 and Value 3 offers you "Help" while value 2 doesn't. it should show a table that says
Features Value 1 Value 2 Value 3
Help YES NO YES
I am trying to create a drop down list which depend to the value selected from the previous drop down list. I can add it without problem, but If I change again the value of the first drop down list I would like to remove the previous drop down list generated from the first value. If I try to remove it when I create the element, it even does not create the element, the remove element function seems to work because when you click on the remove link it works.

I am working on a site with a left menu that slides out, and I've converted it to the top to drop down. So far, it is working ok, but the submenu items need to be below the parent, preferably left aligned. I have played with it a bit and so far can't seem to achieve what I want. See below where I'm clicking Resources and the menu is way too high and over to the right.

I'm trying to get drag and drop script working from this tutorial: [URL]. I want to drag items between columns (DIV's).
Here is my code:
document.onmousemove = mouseMove;
document.onmouseup = mouseUp;
document.onmousedown = mouseDown;
window.onload = function(){
// Create our helper object that will show the item while dragging
dragHelper = document.createElement('DIV');
dragHelper.style.cssText = 'position:absolute;display:none;';
CreateDragContainer(
document.getElementById('DragContainer1'),
document.getElementById('DragContainer2'),
document.getElementById('DragContainer3')
);
document.body.appendChild(dragHelper);
} .....
Every top level item in these containers should be draggable. Do this by setting the DragObj attribute on each item and then later checking this attribute in the mouseMove function
for(var j=0; j<cObj.childNodes.length; j++){
// Firefox puts in lots of #text nodes...skip these
if(cObj.childNodes[j].nodeName=='#text') continue;
cObj.childNodes[j].setAttribute('DragObj', cDrag);
}}}
This script is working only particularly: [URL]
Is there a way to make a form label change color when, eg: a checkbox is checked, a menu/list item selected, or a radio button clicked?
Let say the label was dark gray and then will change to green when it is selected.
The bad news is I do not have the slightest clue as to how this is going to happen or if it is possible with Javascript. I searched Google but nothing Is this possible?
I have a scenario where I show a drop-down-with-few-items in a JSP page, to the user.
The length of few options in the drop down is greater than that of the drop down's, hence our requirement is to show the hovered (not selected) option as tooltip for user's convenience. I am not able to use title attribute for displaying tooltips in my browser.
Now the code ...
implements a tooltip for multiple select drop down menu.Can you modify the code for single select

I have a dynamic table where I would like to update cells by using a drop list selecting from half a dozen items. I have searched W3Schools for a tutorial but I am obviously looking in the wrong place. The working code I have thus far is:-

var a=x.insertCell(0);
var b=x.insertCell(1);
var c=x.insertCell(2);

var e=x.insertCell(4);
var f=x.insertCell(5);

grab the selected value from a drop-down. The alert just shows an empty message. At least it is not showing undefined (as it was for my other attempts - you can see what these were from the commented out code), but I would expect it to display one of the values One-way, Reciprocal or Other. Perhaps I have to do some conversion on the result.
In my HTML I have:
<select name="dllViewSelector"
onchange="showSelectedView(this, allViews, allSections,4,10)">
<option id="oneway_4" value="one" selected="selected">One-
way</option>

There is a drop down list on my Web page with various values to be
selected by the user. Once the user has selected a value, he/she clicks
on the submit button. When he/she does that I would like 2 things to
happen: the selected value of the drop down list is passed to another
html page which opens in a new brower window open.
I can't seem to get a drop downs selected index.
This is my drop down box code...
I've tried searching the forums extensively for this, but to no avail, so apologies if it's already been covered..
As the subject of the thread reveals, I want to create two sets of drop down menu's with the contents of the second being triggerred by the option selected on the first. However, I want to retrieve the options set for the 2nd menu via a php/mysql query.
I.e Menu 1 boasts: Users and Members for options.
If I select Members, I want a query to run that selects all Members and outputs as via menu options.
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".
