is 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.

I 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?
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 1 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. ; (
Code:
var unicodeEscape = function(str) {
var code, pref = {1: '\x0', 2: '\x', 3: '\u0', 4: '\u'};

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:
I'm trying to convert the String "Hopper" to ASCII code and this is what I have so far. Unfornately, it only displays the ASCII code for the last character or 114. And I would like to the code to display all the codes for every character.
Code:
<script type="text/javascript">
function thisFunction() {
var someString = "Hopper";
var j;
