SELECT Equivalent Of An INPUT DefaultValue?
Jun 17, 2011
Interesting question: Does a form SELECT have an equivalent to a form INPUT type="text" defaultValue?
For example: if an input field has a value of "Click Here" when a form first loads, and is set to become "" (blank) when focus is put on it, you can have JavaScript set the value to defaultValue ("Click Here") upon blur if nothing was typed.
Is there an equivalent for a SELECT option? If a different option is selected, can you compare that new option selectedIndex value to the original option selectedIndex value that was when the form first loads?

I'm trying to make the cursor focus on a certain input element when someone hits a certain key combo (such as Shift+S). Does anyone know how you attach a listener like that and bind it to a key combo?

been lurking around to see if I could find any kind of solution to what I'm trying to solve, but the closest thing I got was this old thread:What I wantI'm trying to create is a SELECT menu with an INPUT field, but the INPUT field won't display before I select an option from the list. After I've selected an option I want two things to happen; the INPUT field displays and a new SELECT menu shows up with some other options.Then in the last menu, where I create the options of course, theres a final option that finalizes the entire SELECT menu and gives them a button to submit it, and when they press it, all the options will just be printed along with what the user typed in the INPUT fields.
The problemI have no idea how to automatically show the next SELECT menu, which I've created, but hidden, for the user with it's own text field, and then in the end make it possible to submit it to print all the selected options and whats typed in the INPUT fields.I'm guessing I need some sort of jQuery/JavaScript, but I'm not very familiar with that

Is there a way to achieve multithreading in JavaScript? I'm looking to
fetch a page into a div while allowing the user to interact with another
div. At some point the newly fetched page contents will be available to the
div that the user is working in but I don't want to cause unnecessary
blocking. I've thought of using frames (would prefer divs) plus timeouts
and checking for when a load completes. Does anyone have an idea of how
this could work?

A friend of mine has built as simple site for use on his company's
intranet. It uses JavaScript to read comma-delimited information from a
text file and displays it in tabular form.
When I looked at the source there is js like this:
function forwardClick() {
if (sitelist.recordset.AbsolutePosition !=
sitelist.recordset.RecordCount) {
sitelist.recordset.moveNext();
} else {
alert("You are already at the last record in the database.");
}}
and HTML like this:
<OBJECT id="sitelist"
classid="clsid:333C7BC4-460F-11D0-BC04-0080C7055A83" border="0"
width="0" height="0">
<PARAM name="DataURL" value="sites.txt">
<PARAM name="UseHeader" value="True">
</OBJECT>
Obviously it's a Windows and IE only thing but is there an equivalent
for non-IE browsers and/or non-Windows OS?

wondering if there is a va_list equivalent in Javascript. Well,
actually, I know that there is, but I don't know if its user...
applicable. va_list in C/++ anyhow is a way of being able to pass in
any number of arguments at the end of a function, I'll show an example:
Code: ( text )
Header:void addLine(int, const char*, ...); cpp:addLine(int line, const char *string, ...) {char *output;va_list args;va_start(args, string);vasprintf(&output, string, args);va_end(args);}
So as you can see, the space is reserved at the end of the function
declaration with the "..." syntax, and in the function body is expanded
and processed. I could be way off here, but I think I'm on the right
track.

I'm trying to find out if javascript has something akin to $$ in php.What I'm trying to do:
var costs = {
cost1: 5,
cost2: 10,
cost3: 15
}
// Retrieve cost user has selected
alert(costs.selectedCost);
Its obviously a hyper-simplified example of what I'm trying to do, but the premise is the same. In PHP, I could use $$ to convert one variable into another, not sure if JS can do the same.

I use php to output a foreach loop on a table (example below), so when I hit submit on the values each of the rows are submitted to the database.
However, my problem if this. If you look at the below I use a bit of JS on the <select> box which when selected should automatically populate the corresponding start_time[] <input> box, however I can't seem to get it to work?
[Code].....

I've been using display:none on the style property of some <option>
elements in my forms, which works fine with Mozilla - as expected it
removes the option from my dropdown (although it still exists in the
code). Is there an equivalent in IE?
The reasoning behind this is that I want users to rank objects using a
<select> for each place (see below), and to remove the choice of earlier
objects from <select> drop-downs later in the list.
1st place: [<Select> with option 2 chosen]
2nd place: [<select> with option 4 chosen]
3rd place: [<select> --> Option 1
Option 3
Option 5
Option n]

Mozilla-equivalent of the following line of code:
document.getElementById('editorContent').contentWindow.event.srcElement.href
The purpose of this line is to get the "href" value of a link when clicked on inside a content-editable iframe.I have the function working perfectly in IE, but not having much luck with Mozilla browsers.

Whats the Javascript equivalent for PHP's file_get_contents ?
<script type="text/javascript">
document.open("http://anotherpage.php"); // I know this is not the way because this opens a new page
</script>
Any way without using frames ?

I'm making a <select></select> with lots of <option></option>. It
contains all possible options. Because of the length of the list, I
also have an <input type="text">.
This is what I wish to do:
onKeyDown I want all options that don't contain (or begin with, it
doesn't matter which one) the typed letters to be removed from the
<select>.
My problem is that I don't know of any code to find words and identify
letters.
