View 1 Repliesis 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.

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?
I 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)?
I've found some routines on the 'net that will convert 7-bit ascii to hex, but I'm interested in converting all valid javascript characters (16-bit unicode) into hex. and with javascript.
View 2 Replies View RelatedI have a function that lets me convert one character and throw an alert
with the corresponding ASCII value, but what I am having trouble with
is applying it to a text box. What I'm trying to do is when characters
are entered the function will loop through the entered values and throw
an alert for each of the corresponding ASCII values for each of the
characters entered. I am trying to alert the user for every character
that is out of the range of ASCII equivalent 1 - 128. Test code:
I'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. ; (

I 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?
Most 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.
Here's what I have so far, which handles characters
as they're typed in. Could someone please show me how I would loop
through all the values that are entered if a block of text was pasted
in, and then grab the ascii value(s) that are > 128?: Code:
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.

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

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

Mozilla-equivalent of the following line of code:

Whats the Javascript equivalent for PHP's file_get_contents ?
