Displaying Upper ASCII (code 128-255) In Alert() Window.
Jul 23, 2005
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: 68°F";
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.

Code:
<script type="text/javascript">

var someString = "Hopper";
var j;

I am in the process of learning javascript and I've been looking at this code for the longest time ever. So far I got most of it done. For example I leave all the required fields empty, it gives me the alert message of the first field and not the alert messages of all the others. What I want to know is how can you go through and check the whole form first before submitting and then when there is any error on any field, shows just one alert message containing all the error messages.
Code for the form
<form action="mailto:hummdedum@felloff.com" method="post" name="form" onSubmit="return isFormValid();">
* First Name: <input type="text" name="FName" id="FName" onblur="checkFName();"/><label id="labelFName"></label><br />
* Last Name: <input type="text" name="LName" id="LName"onblur="checkLName();"/><label id="labelLName"></label><br />
* Password: <input type="password" id="pw" name="Password" onblur="checkpw();" id="pw"/><label id="labelpw"></label><br />
*Re-type Password: <input type="password" name="2Password" id="pw2" onblur="checkpw2();" /><label id="labelpw2"></label><br />
I am a: <br />
<input type="radio" name="status" value="fresh" /> Freshman<br />
<input type="radio" name="status" value="soph" /> Sophomore<br />
<input type="radio" name="status" value="jr" /> Junior<br />
<input type="radio" name="status" value="sr" /> Senior<br />
I am taking classes in the: <br />
<input type="checkbox" name="semester" value="fall" /> fall time<br />
<input type="checkbox" name="semester" value="spring" /> Spring time <br />
My favorite element is:
<select name="element" id="element">
<option value="">select one</option>
<option value="fire">Fire</option>
<option value="earth">Earth</option>
<option value="water">Water</option>
<option value="air">Air</option>
</select><br />
*Birthday: <input type="text" id="BDay" name="Birthday" onblur="checkBDay();"/><label id="labelBDay"></label><br />
*E-Mail: <input type="text" id="email" name="Email" onblur="checkEmail();"/><label id="labelEmail"></label><br />
<input type="submit" value="Submit" />
<input type="reset" value="Clear" />
I want to also validate birthday.. and I tried using regular expression with leap years but the expression is too hard for me to think of. So I am gonna try using split() but I don't know and for the clear button. Since I blur functions, how would I just clear all the blur statements = like a restart of the form and then when the user enters the field the blur function still works?

I am a novice, almost to an intermediate-level JavaScript guy, so much of this is new to me. I appreciate your patience reading this.
I have a routine that creates some HTML on the fly (updateFilters() function) and after the HTML is created, I attempt to access some fields (elements) on the form itself.
I works fine if I place an alert() statement after the HTML is created, but when I remove, the code errors out.
I have tried the setTimeout() statement, but I cannot grab the element --- undefined or null is returned. It seems that the form is the only element I can get a handle on --- everything else is undefined or null...
Here is the code:
function editQuery() {
var f;
var x;
var myForm = document.forms[0];
// Get the row filters that were used in the last query..
for (f = 1; f < 16; f++) {
var filter = eval("myForm.FilterList_" + f);
if (filter.selectedIndex > 0) {
var methodElement = element("FilterMethod_" + f);
var methodIndex = methodElement.selectedIndex;
var savedFilterMethodValue = methodElement.options[methodIndex].text;
var choicesElement = element("FilterChoices_" + f);
var choicesIndex = choicesElement.selectedIndex;
if (isNaN(choicesIndex)) {
var savedFitlerValues = choicesElement.value;
}
else {
var savedFitlerValues = choicesElement.options[choicesIndex].text;
}
updateFilters(filter); // update the filters
// take the saved methods and values and then update the selections
// Alert here makes the code work..
// alert("Try this");
// Wait for HTML..
setTimeout("completeEdit()", 1000);
function completeEdit() {
// Since the object was updated, get the object again..
var methodElement = element("FilterMethod_" + f);
for (x = 0; x < methodElement.options.length; x++) {
if (methodElement.options[x].text == savedFilterMethodValue) {
methodElement.options[x].selected = true;
break;
}
else {
methodElement.options[x].selected = false;
}
}
// Since the object was updated, get the object again..
var choicesElement = element("FilterChoices_" + f);
for (x = 0; x < choicesElement.options.length; x++) {
if (choicesElement.options[x].text == savedFitlerValues) {
choicesElement.options[x].selected = true;
break;
}
else {
choicesElement.options[x].selected = false;
}
}
// Only display next row if f = 2..
// If only one row was used, no reason display the next row..
if (f == 2) {
displayNextFilter(f - 1); // display it
}
}
clearTimeout(timeOut);
}
}
}
Do I have to pass the object (the form, the elements) to the completeEdit() function in the setTimeout() statement?

I'm new here and I have tried to search the forum, but there was nothing fitting to my problem.
I would like to display content in an alert box. Sounds simple, but the content is fetched immediately, so I have no influence on that[code]...
This responseText is quite long and I need to display it in more than 2 lines.
Im doing some security research for my master thesis and am a JacaScript newbie

My group is working on a basic document management system that includes four users. staff member, department director, division chief and clerk. The programming language that we used is PHP.when staff member logs-in on his homepage and uploads a file he must choose reviewer from a dropdown menu that consists of dep. director and div. chief.When he clicks the upload button the homepage of who he chose as reviewer should receive a prompt/alert box upon log-in saying "you have a document to review".For example:if he chose division chief as the reviewer when the person logs-in on his homepage a prompt/alert should display that he has something to review.The code for uploading file is already up and working.

Basically what I need to do is cause a bit of HTML to only display on a specific page. I have figured out how to do most of the work i.e. figuring out what page that the code is being displayed on, etc. However, for some reason the DOM element that I am using will not update based on the Javascript.
Here is the version of the code that I am currently working on:
<html>
<head>
<script type="text/javascript">
window.onload = function DisplayButton() {
var DesiredPage = 'Page to Display';
//Page that I want the code to display on
var sPath = window.location.pathname;
var sPage = sPath.substring(sPath.lastIndexOf('/') + 1);
//This determines and places in a variable what page that the code will be on
if (sPage == DesiredPage) {
document.getElementById('HiddenCode').style.display = "block";
}}
</script>
<p Id="HiddenCode" style="display:none">Code only to be displayed on indicated page</p>
</head>
</html>

This is probably the weirdest thing I've ever seen. I know the code works since Firefox will output things, but it ONLY outputs when I throw in an alert statement somewhere in the function that gets called. It doesn't matter if it's at the beginning and just says Hi, but then it will run correctly. Without it, Firefox won't go through the function apparently and won't write out the results. I don't understand why this isn't working or why firefox is doing this.

This one is throwing me. I have a small piece of code that I am using to call a function in dynamic drive's accordion menu script. As long as I leave the alert() line in, it works. Comment it out and the call to expandone() doesn't go through. I must be missing something obvious, no? Here's the relevant part of the code (it is fired from $(document).ready() ):

I'm writing a webpage that uses JS to copy the tag elements STYLE and a table into a new window that is not displaying content from using .cloneNode(). I've used alerts to verify that the command is getting all the HTML but in the new window, the table is not being displayed but the last bit is. Since I'm using only one strings to handle the entire HTML of the new page, I'm missing why only part of the string is sent to the new window. It's a real pain to debug since because the new window is generated entirely with JS, there is no source for me to see exactly what is happening.
Here's the code for what I'm talking about:
PHP Code:
printPIM = function() {
w = window.open("about:blank", "printWP", "scrollbars=no,directories=no,resize=no,width=1020,height=700,toolbar=no,menubar=yes,copyhistory=no");
w.focus(); // Makes sure the new page isn't hidden
style = pimStyle.cloneNode(true);
p = pimTable.cloneNode(true);
wt = "<html><head><title>" + PIMName + '</title><style type="text/css" media="print, screen">' + style.innerHTML + '</style></head><body>';
wt += "<table id='pimTable'>" + p.innerHTML + "</table>"; // Adds the PIM table
wt += '<div style="text-align: center;"><h1>Total Distance: ' + parseFloat(TotalDistance).toFixed(precision) + 'nm</h1></div>';
wt += '</body></html>';
wt.replace("<tbody></tbody>",""); // Remove extra tbody element
w.document.writeln(wt);
return false;
}
The only thing displayed is the contents of the DIV element.

I'm trying to run through the simplest tutorials on jquery and for some reason I can't get any of the jquery code to work.I've downloaded jquery and I've made sure that this file is in the same directory as jquery-1.3.2.js.This is the code taken from the tutorial:
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">[code]....
when the user clicks on the link it shouldn't take them to [url]....instead it should display an alert box. but it takes me to[url]...every time.

I am putting together a simple edit in place script. For some reason, in order for for the editEffect function I've created to work I need to use the alert function as seen in the code below. I can't figure out the cause of the problem and I believe the root cause is also creating other problems - i.e. in the cancelEdit function the argument "targetElement" is not alerted, but it is successfully submitted as an argument to another function.
/* Edit in place javascript code */
function editLightOn(element){
element.style.backgroundColor = "#ffc";
}
function editLightOff(element){
element.style.backgroundColor = "#FFFFFF";
}

My website was recently ftp hacked and a file inserted into it - js.php - which seems to be some sort of advertising spam programme. Having spotted the file I have renamed it to hide it but lots of other sites are still referring into my site looking for this php file. What I would like to do is to *just* open a java alert box on the referring sites to alert the users that the site has been hacked and that they should notify the webmaster so that he can fix his site.The line referring into my site is -
<script type="text/javascript" src="http://www.mysite.com/js.php"></script>
Is this something simple to do?

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've got a page that lists a bunch of info in a large table. In each row is a link, and when that link is clicked on, an ajax call fires that returns detailed info on the item in that row. I usually display the html just to the right of the table, but the table has gotten too large. I need to display the info in a pop up now. The only thing is, how do I get the results of my ajax call into a pop up window? I've been having an awful time getting this to work.
I'm using JQuery to make the ajax call, what can I put in my success of complete event to create the pop up using the data the ajax call returns?

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 need to display a set of images. NOT a slideshow that automatically changes, but a very simple display, one image at a time, that moves to next or previous by mouse click or arrow.
I can retrieve the set of filespecs in php with no problem. And I've got the setup in php to display the file, one at a time.
I"ve figured out how to open a full-screen window in javascript.
What I need (I started in php and they sent me over here for specific javascript info), is to put everything together...
1. I'd LIKE to automatically set the resolution on the system to 1024x768. I've been told html and javascript can't do that, so it'll have to be done by the user.
2. I figured out how to open a full-screen window in javascript.
3. What I need is to display the image from php and have it show up in the full-screen window I created. Then it just sits there until the user presses an arrow key (or hopefully something with the mouse) to go to the next (or previous) image. Back to php for the next file and display...
Once the last image in the set is displayed I'd like to have the window I created go away, sending me back to the screen from which all that got started...
So, as far as I know, the two things I need to know are how to display an image in a particular window from php. And, how to get mouse-clicks and/or arrow keys back to php so I can use them....

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)?
