Ord(ascii) ?
Mar 22, 2006is there a function to tell me the ordinal value of an ascii character in a string. What I'm trying to do is to find out how a tab character in MS Word gets pasted into the TinyMCE editor. I had no luck finding any tab in the string, so I would like to see what is in that position.

Jul 23, 2005I have this string: "60 105 109 103 32 115 114 99 61 34 101 108 111 46
106 112 103 34 62", and I'd like to convert it to the characters. I've
used the split method to separate it but I don't know how to transform
each number in the character. Could you hel me?
Need An Ascii Image Format!
Jul 23, 2005I developing a system using JSP. People familiar with this technology
know that ServerPages are easier to maintain than Servlets, but they
can only have ASCII output.
With that as the backdrop, here's what I want to accomplish. I want
clicking on a link to cause a script to be executed on the server but
-->I don't want the browser to jump to another page<--.
A solution that I conceived was to have javascript like
someimage.src = 'http://myscript'
This will accomplish the task and it would be great if myscript return
an image of a checked checkbox! But, because of JSP limitations this
would need to be an ASCII image.
So my question is twofold:
1. Are there convenient ASCII image formats?
2. Is there another way to accomplish what I want (trigger some action
on the server without jumping to another page and using js to display
a sensible response - something like a check)?

Mar 10, 2006I have a function that lets me convert one character and throw an alert

Unicode Escape Non-ascii Chars?
Jan 1, 2009I'm looking for a function that will convert non-ascii characters to unicode escaped string.For example, "あ" => "u3042".A similar piece of code is below. However, it convert strings to "\uxxxx" instead of "uxxxx". Changing "\" to "" in code below still won't work because that result in 'u' + 'xxxx' which print as "uxxxx".I have been searching for a few days already, and start wondering if this is at all possible. ; (
Code:
var unicodeEscape = function(str) {
var code, pref = {1: '\x0', 2: '\x', 3: '\u0', 4: '\u'};

Need To Convert From Ascii To Its Ingeger Number
Jul 8, 2010I have a quastion, I am currently passing in a number as a string to my function (this is hard to change since its a program that generates the numbers).
For example i pass the number function random('252'), but what I want is this
function random(252).
So my quastion is, do you guys have a clever idea on how to take this string, this ascii number and convert it to its "real" integer value, so that i can make correct calculations?
Displaying Upper ASCII (code 128-255) In Alert() Window.
Jul 23, 2005Most of these characters are not on the standard keyboard.
Here's a successful contrivance, with comments & cautions,
a little page that works in IE6.
<HTML><HEAD><SCRIPT TYPE="text/javascript">
function alt() {
document.all.s1.innerHTML="Current Temp: 68F";
var txt=document.all.s1.innerText;
alert(txt);
}
</SCRIPT></HEAD>
<BODY>
<INPUT TYPE="button" VALUE="Temperature" onClick="alt()">
<P ID="s1" STYLE="visibility:hidden"> </P>
</BODY></HTML>
comments: The innerHTML property is needed to produce the
character glyph from the entity code. If the entity string
were passed to innerText(in 1st statement) then the code
would remain literal.
This work-around depends on s1 being rendered before alt()
is called. It will not work as immediately executed code,
because element s1 would not exist yet.
cautions: Trying to style alert's display will produce error
msgs. Do not use <B>, <U>, or <I> tags in the argument
string. No Heading tags either.
Strange enough, an inline STYLE, setting font values, say,
does not give error msg, but will not execute either.
Alert ignores it.
You can use <BR> tags in the argument, which give the same
result as
in a direct arg to alert().
In sum, you can tell alert what characters to display,
in what order, and on what line, but you cannot tell
alert HOW to display them.

Multithreading? Or The Equivalent?
Jul 23, 2005Is 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?
Non IE Equivalent To IE's Data
Jan 12, 2006A 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?
Va_list Equivalent
May 7, 2006wondering 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.
JS Equivalent To PHPs $$?
Mar 10, 2010I'm trying to find out if javascript has something akin to $$ 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.

Jul 23, 2005I'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
