Mar 27, 2011When I run the following code, the .Length function returns "undefined."

Makes User Enter Answer Twice Before Prompt
Jun 10, 2009The application works fine but it makes the user enter the answer twice before it brings up the question "Would you like to continue?". I thought the fix would be to just call "myMH.checkAnswer(studentAnswer);" straight from the method in the "appclass" but that didn't fix it I m so lost on this problem. This problem most likely is right in front of my face but don't see it lol. I have another question as well but I think if I get this one figured out first it might answer my other one.

In IE, Forcing Focus On Window Makes Dropdown Selects Inoperable
Jul 23, 2005We are developing a web page that shows large graphics. To provide more screen space for the graphics, we allow the user to popup a window that places itself over the top part of the browser. This popup contains a control panel that tells the main window what to display.
Because we don't want to require that the user continually ALT-TAB to go between the main window and the popup (all user controls are on the popup) in the control panel popup, we have the following:
in the function called by onLoad in the popup, the following line is executed:
window.onblur= keepFocus;
later in the .js file we have:
function keepFocus() {
self.focus();
}
The problem is that when the user tries to use a dropdown select control the list drops down and immediately rolls back up, making it inoperable. This doesn't happen in the Netscape/Mozilla family or browsers. Nor does IE report an error.
JQuery :: Cycle Plugin Makes Clicking Sound When Changes Slides Only On IE?

HTML5 Database Insert Statement Makes Browser Crash
Nov 1, 2010I have this table:CREATE TABLE IF NOT EXISTS Assignments (uid TEXT PRIMARY KEY ON CONFLICT REPLACE, instruction TEXT, start TEXT, stop TEXT, createdTimestamp TEXT, theTimestamp TEXT, taskID TEXT, resID TEXT, flowID TEXT, flowDefID TEXT, currentState TEXT, iconRef TEXT, colorRef TEXT, dispatched BOOLEAN, inStartState INTEGER, inStopState INTEGER, writeLock INTEGER, workItemID TEXT, companyID TEXT, metadata INTEGER)
The thing is that when making a insert and then going to the development toolbar in chrome and look at the storage tab and look at my table. Depending on what is in the table chrome crashes.I drop the table between the executions.The difference here is that "theTimestamp" is something rather then empty. If I set theTimestamp to '10/15/10 3:07 P' it works. But just adding that last M or any other letter will make chrome crash when you try to look at the table. Whether it is by navigating to the table with mouse clicks or writing a select * from Assignments statement.
Eval() How Else
Jul 23, 2005given that I have a js file included which is written programatically and I
can't change it. I would like to know how to do the following using
something other than the deprecated eval().
whats in the js file
var numArrays=something;
var data0 = new Array();
data0.name="name";
data0.data="some data";
var data1 = new Array();
data1.name="another name";
data1.data="some more data";
etc ....
function getData(arrayName) {
for ( var i=0;i<numArrays:i++) {
var el=eval('data'+i);
if (arrayName = = el.name) doSomething(el.data);
}}
How To Use Eval?
Jul 23, 2005var fns = ['orde', 'no', 'kml', 'snf', 'td', 'ty', 'tn', ...up to 21
elms...];
var snv = new Array();
var vals = new Array();
for (i = 0; i < N; i++) {
for (j = 0; j < fns.length; j++)
vals[j] = some value;
snv[i] = new makeData(vals);
}
function makeData(vals) {
for (k = 0; k < vals.length; k++)
//the following line doesn't work
eval("this."+fns[k]+"="+vals[k]);
//neither this one
this.eval(fns[k]) = vals[k]);
}
how can i make it without writing it the long way:
this.orde = vals[0];
this.no = vals[1];
this.kml = vals[2];
and so on?

Using Eval()
Jan 28, 2004I've made a funny program using eval()...it will let the person(on the page) to write javascript and have it compile(if thats the right word for it)! its quite cool, i dont know how handy it might be, but here it is none the less...
code:
<html>
<head>
<title>test</title>
<script language="JavaScript">
function submitCode(){
var the_code = window.document.form_1.textarea_1.value;
var run_the_code=eval(the_code);
}
</script>
</head>
<body>
<center>
<h1>write some code!</h1>
<form name="form_1">
<textarea name="textarea_1" rows=10 cols=40>
</textarea>
</form>
<form onSubmit="return false;">
<input type="submit" value="submit your code" onClick="submitCode();">
</form>
</center>
</body>
</html>
very simple stuff, but for those of you who are unfamilir with eval, its pretty cool, huh?
Load The Word The User Inputs And Makes It Bounce Around The Canvas As Well As A Text Spinner
Jan 25, 2011I have been practicing using canvas to make designs. My current code below will load the word the user inputs and makes it bounce around the canvas as well as a text spinner. However, whenever the user inputs a second word, the bounce below stops to start a new one and the text spinner messes up. so when the user inputs another word, that it either reloads a new textspinner or adds another one, as well as just add the word to the canvas without stopped the old one.

AJAX :: Auto-Refresh - Page Thats Makes An Call To The Server Gets The Time And Displays It
Mar 2, 2009I have made a page thats makes an AJAX call to the server gets the time and displays it. In the OPEN method i have set
req.open("GET","/timerProg.cgi?param1="+new date(),false);
I have set the last parameter as false as i am expecting a synchronous request so that time displayed should be consistent.
I am using new date() since the browser is caching my request and displaying the same output everytime as i dont know any other alternative.
The alternative so that browser does not cache the results and gives proper output each time.
Eval And Continue
Aug 23, 2005I'm having some weird problem with evaluating the continue statement.
Within a for loop I'm trying to evaluate a string (generated somewhere
earlier) which basically has the continue statement in it. IE6 seems to
have major problems with that as it generates an error "Can't have
'continue' outside of loop". Does anyone know why and/or have a
workaround? I haven't tried any other browser since this one is the
only one available (company policy).
I have included some code to reproduce this behaviour. The first and
second if statements of the testeval function behave as expected. The
third one however produces the mentionned error. Code:

Eval Problem
Aug 30, 2006I'm running some javascript over a server side generated web page
and have multiple generated empty select statements, that I want to
populate when the page is loaded. As HTML doesn't do arrays each
select is individually named withe MySelecti where i is an incremental
from 1.
I know all my variables are correct (i, OptionsCount) and my arrays
of MyValues and MyDescription's exist for multiple enteries and if I
bring out an example of what I thought each line would eval too( say
document.MyForm.MySelect1.options[1]=new
Option('Value1','Description1') the line works fine, for the life of me
(i'm sure I'm missing something obvious) the eval line won't eval..
for(i = 1; i<=row; i++) {
for (j = 1; j <=OptionsCount; j++) {
eval="document.MyForm.MySelect"+i+".options["+j+"]=new
Option('"+MyValues[j]+"', '"+MyDescription[j]+"')";
eval(eval);
}
}
