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 have a HTML form which takes some values including a password field. I have a JS function to check and alert when a user enters some particular special characters(this is bcoz only these characters are not allowed in the back end of the html form, all the other special characters are allowed). following is the code for it.
function checklen()
{
var iChars = "`<>";
for (var i = 0; i < document.ipform.password.value.length; i++) {
[Code]...
now i want a feature which does'nt allow the user to enter an uppercase letter or a special character(only these are allowed~@#$%^&*()-_+|) as the the first character of the password field. Since i am newbie to JS, It would be a great help if some one can help me to sort out this..
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.
View 1 Replies View RelatedI 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.

Here is the vb equivalent:
I 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:
Heres the code:
case "D": if ((Number(a1)==1) && (t.getDate()<10)) str+="0";str+=t.getDate();b
Its part of a date script. if i use
<!--
<![CDATA[
]]>
//-->
then the script doesnt work - but it is validXhtml....
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.

<script type="text/javascript">
function thisFunction() {
var someString = "Hopper";
var j;

I did try searching first but for some reason when I put this character in google search fields I never find what I want, maybe not being recognized.
here's the code

what is the || character(s)?
Does anyone know the escape character for & and # like in :

I would like to insert & and # literally in the table.
I have a string that I'm properly URL-encoding to be passed in a URL.
Here's the tag from the HTML source:
<A HREF="javascript:openPopWin('takeit.php?568&10&dr.+hobo%27s+scalpel',
325, 325, 'scrollbars')">
But when I mouse-over the link, the %27 shows in the status bar as a ' and
when I click on it, I get a JS error because of the extraneous '. The +s
are not being decoded - why is this one character, and is there a way to
prevent it?
I had a difficult time figuring out how to get or test the last character of a string with javascript.
I found plenty of removing the last character, but not for just checking what the last character of a string is using javascript.
// create string
var str = new String("No Periods Allowed.");
// alternatively get string from field:
// var str = document.getElementById('textbox').value;

Well, finding that easily on a search would have saved me some time.
i have a little problem with the follwoing JS, when i count characters for Input type text the reult is ok but when i am using textArea it says 'NAN' here is my code,

I was wondering if there was any easy way to do the following in javascript:
I have two form fields, firstname and last name, as the user enters their information into a form I want to be able to show them what their username is going to be.
While they enter the information into the fields I was hoping to have it generate the username as the type.
I need to take the first letter of their first name (the first letter in the firstname field) and the entire lastname to combine it into a username. Except if there are spaces or any other characters such as dashes apostrophes they must be removed.
I have a simple AJAX script set up where the XML retrieved populates a DIV.
One XML field can be quite large. For example, one is 35,961 characters
long.
When viewed, the data seems cut off. Is there a limit to how many
characters Javascript can read into a string variable and pass to
innerHTML?
If so, what is that limit? Not to mention...any ideas on a workaround?
The follwing function is in an onkeypress event for some textboxes. How can
I cancel the keystroke? or more importantly it's output. This function does
what I want it to do, but it actually writes a space in the textbox. I
wanted to escape out of writing the character. Especially if I change it to
another keyCode besides space bar. Any ideas?
function setEfforts(ctrl){
if(event.shiftKey && event.keyCode == 32)
{
var row = ctrl.parentNode.parentNode;
var inputs = row.getElementsByTagName('input');
var textboxes = new Array();
for(var x = 0; x < inputs.length; x++)
if(inputs[x].type == 'text'){textboxes.push(inputs[x]);}
for(var y = 0; y < textboxes.length; y++)
textboxes[y].value = ctrl.value;
}
return false;
}
I am struggling to find definitive information on how IE 5.5, 6 and 7
handle character input (I am happy with the display of text).
I have two main questions:
1. Does IE automaticall convert text input in HTML forms from the
native character set (e.g. SJIS, 8859-1 etc) to UTF-8 prior to sending
the input back to the server?
2. Does IE Javascript do the same? So if I write a Javascript function
that compares a UTF-8 string to a string that a user has inputted into
a text box, will IE convert the user's string into UTF-8 before doing
the comparison?
I think that the answer to question 1 is probably "YES", but I cannot
find any information on question 2!
I have had this function work perfectly in IE and am trying to get it
to work in Firefox. I have seen plenty of questions and answers on the
web for how to get and check the key pressed but nothing about setting
or changing it. I only want uppercase characters in this case. If the
key is a lowercase, it needs to be changed to an uppercase character.
IE lets you use keyCode to change the character code. How do I do the
equivalent in Firefox?
<textarea cols="40" rows="3" name="Rule" id="Rule"
onkeypress="checkUppercase(event);"></textarea>
function checkUppercase(e) { .....
Anyone know if it's possible to convert the co-ordinates of a click on
a div into a character position within the div's content?
How do I onBlur prompt the user to enter a ZERO as character one, if one is
not already entered. At the same time, I would like to ensure at least 5t
characters have been entered. This validation should also only trigger if
anything is entered. Basically, if the user chooses to enter nothing then
the check should not be carried out and the user should be able to continue.
So in pseudo style:
If user data IS ENTERED AND DOES NOT contain a ZERO as first character, or
is LESS THAN 5 characters long, prompt for re-entry.
Thanks guys, been trying various things and got close, but have hit a brick
wall.
This ALMOST works:
function checkField()
{if (document.form1.Bsk01.value.length<9) {alert("Please enter a valid code.
The first character should be a zero.")}else if
(/^0.*$/.test(document.form1.Bsk01.value)){return;}else{al ert("Please enter
a valid code. The first character should be a zero.")}}
