In PHP, there is a require_once() function which includes a file only
if it is not already included. Is there an equivalent function in
Javascript (one that checks if a .js file has been included)? If not a
straight-up function, is there some other way to check if a javascript
file has been included already?
I want to do some Win32 application automation from JavaScript. Is it

Does anyone know a way of passing parameters into a Javascript script 'from

idea of CGI parameters?
Whats the Javascript equivalent for PHP's file_get_contents ?
<script type="text/javascript">

Any way without using frames ?

View 1 Replies View RelatedI'm looking to return DATE ONLY for yesterday's date. No seconds,
milliseconds. Formatted either yyyy/mm/dd or mm/dd/yyyy. VB does it so
easily Date()-1 will return 03/27/2007 if today is 03/28/2007. Why so
many hoops for javascript? Any ideas?
I am using a location in my javascript: '../../myfolder/myfile.asp'
I want to make the script reusable by pages in different folders. The 'myfolder' is in the root of my site. How can I target this from any other folder such as the vbscript server.mappath('myfolder/myfile.asp')?
What is the best way to get just the script name that is running without the path and parameter info? This would be the JavaScript equivalent to the PHP command:
basename ($PHP_SELF);
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 have been trying to figure out how to access files on different servers through javascript, as i am converting an onsite myspace app to an iframe app, i need to get the contents of a file from the last.fm api and store it in a variable. Or maybe i could get it with php and store it in a javascript variable if that is possible,
View 3 Replies View RelatedIs there a javascript equivalent of PHP's nl2br() function? I have to send the value of a textarea to a new window that will display the text of what was in the box, which is why I need to somehow convert newlines to breaks.
View 9 Replies View RelatedI'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.

Is there an equivalent in Konqueror's KJS engine to Gecko's
__defineGetter__() and __defineSetter__() methods? Our web application
uses a ton of Javascript, written based on Internet Explorer's object
model as that's the primary platform that we're supporting. For
Netscape support we uses __defineGetter__() and __defineSetter__() to
emulate the many IE-only properties. I've tested our site using
Safari, and to my surprise, it renders perfectly. Alas, it's
completely non-functional. If it's somehow possible, I'd love to write
a similar emulation library for KJS so that our non-Windows users
would have an alternative to crummy Netscape/Mozilla.
I have a couple of simple forms:
[Code]...
but it doesn't work, because it's not passing the variables correctly I don't think. I don't know how to simulate a simple GET posting of a form.. the data line in this code is from another script which uses POST, but POST doesn't work for my purposes so I have to use GET.
<html><head>
<script src="jquery.js"></script>
<script type="text/javascript">
addIframe = function() {
$('body').append('<iframe>');
} appendIframe = function() {
$('iframe').contents().find('body').append('appended');}
</script>
</head><body>
<button onClick="javascript:addIframe();">addIframe</button>
<button onClick="javascript:appendIframe();">appendIframe</button>
</body></html>
Now this work perfectly fine with jQ 1.6.2, but does not work with 1.4.2 because 1.4.2 does not yet know .find(element).
Do we have any equivalent of swapNode method in firefox?
View 1 Replies View RelatedInteresting 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?
