Checkboard Pattern - Three Output Statements To Display
Oct 24, 2009
This code not sure what the final result should be.
<?xml version = "1.0" encoding = "utf-8"?>
<!DOCTYPE html PUBLIC "-W3CDTD XHTML 1.0 StrictEN" [URL]">

<script type = "text/javascript">
<!--
var side = 8;
var row;
document.writeln( "<pre>");
while(side>=1){
row = 8
if (side % 2 != 0)
document.write(" ")
while(row >= 1){
document.write("* ")
row -= 1;
} end while
document.writeln();
side -= 1;
} end while
document.writeln("</pre>")

This what I got when I ran the script. Click Refresh (or Reload) to run this script again. These ere the constraints of the assignment. Write a script that outputs XHTML text that displays the checkerboard pattern: Your program may use only three output statements to display the pattern:
1. Only one document. write( "* " );
2. Only one document. write( " " );
3. and Only one document. writeln(); writes a newline character
You may use XHTML tags (e. g., < pre>) for alignment purposes.
[Hint: Repetition structures are required in this exercise.]
i am having trouble with a program for class hoping someone can point me in the right direction i am supposed to use nested for loops to output 2 seperate webpages one with the first pattern below and then another with the second pattern.
I'm just learning javascript and am editing a calculator form that will calculate square footage and write to a form text field. I have another form filed that I would like to display a number based a series of if else statements. ex: if square footage > 2761 then display 5.0., if square footage > 2521 then display 4.5. etc.
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "<HTML> <HEAD><TITLE>Size Calculator</TITLE> <SCRIPT LANGUAGE="JavaScript"> function CalculateSum(Atext, Btext, form){ var A = parseFloat(Atext); var B = parseFloat(Btext); form.Footage.value = A * B; form.Size.value = 21; }
/* ClearForm: this function has 1 argument: form. It clears the input and answer fields on the form. It needs to know the names of the INPUT elements in order to do this. */
I'm having two issues: First, is there an easier way for my showValue function to display the image file name without running a bunch of if statements? I tried doing something like document.getElementById('imgFile').value = imgArray[n]; but that did not seem to work.
Second, I'm trying to have the image file name change in my textbox when I click any button. I've accomplished this with onblur, but that only works if I click on the textbox. I'd like it to just change automatically.
I would like to some javascript connect to a URL on the same webserver and read a CGI. The output from this CGI is not plain HTML but rather data which needs to be displayed in a moving graph. Coming from a Perl background I'd say I'm looking to do something like:
while (my $data = read_url(http://whatever) { print some pretty moving data across the screen; }
Is something like this possible to do in javascript?
I have some complex (to me) JS code that displays time and date for the selected location from a drop-down. It can handle half hours and DST adjustments. But it only displays the results in IE. Here is where I call it in html. code...
I am having a problem with getting my output to display a dollar sign. I have the program running the way it is supposed to, it just won't format for currency. I have tried a couple of different methods and do not understand why the current code does not work.

I have a website where i use AJAX script and display the output in the Combo Box but i have problem: Combo Box Return values like : 22 23 24 25 (All in one line)But Values should like Combo box values :
When a person signs up for my website it first adds them to my external email list and then to my MySQL database.In order to do this you have to pass the information of the form to the next page where you can "display" it. Nothing except this display function seems to work.So what I am trying to do is take what is outputted by this display button and store it in a javascript variable. Then transfer this variable to a form which will auto submit and start the PHP registration pulling the output of the script, right now I can either get an undefined or the entire HTML code. Is there another option?Here is my code:

outputting the results from a javascript search function onto a new page. Right now I am using a javascript search script on 7 pages and it works but the results overwrite the current page that the search was initiated from. I would like it to open a new page and print out into a specific area. Im not really proficient in js, tho I know enough to get by. since ive been grinding my gears at work trying to get this to display right. I'll post the code tomorrow morning when I get to work so you can see the function.
I have created a servlet that does nothing more than create a XML file.i have got some JQuery code that reloads the servlet to get the XML data.This works fine and i am able to load the data i want, the problem i have is that when the data is loaded to the jsp page it displays [object Document] in front of my output.
I ask the user to enter a time in the formatio 12:30 PM. onChange I send the string to this function. I'm using alert boxes to test it...and am always getting the "Does not work" alert box. What am I doing wrong?
I am sure if I searched long enough I could find the answer, but to save time I would appreciate help with the # statements, such as #include, #csstopmenu, etc which I find in the scripts here and elsewhere. I know that #include is used with shtml to include another html page. What are the others? Is there a definitive list, and if so where can I find it?
I am new to javascript and would like to search for the element with id but the element id are changing if i use different navigation in that web page example: C21_W68_V69_notes_struct.text changes to C24_W78_V79_ notes_struct.text or any other name next time hence i would like to search that element using a pattern like notes_struct.text as there exist only one element ending with this pattern. I am using old version IE and would like to use javascript only.
This code uses a nested IF statement to put a pack of cards into an array of records. But for some reason the cards arn't going in.. like.. at all? I've put a document.write piece of code at end to display the card in the first slot and [object Object] appears? Code:
I have written an ASP.net app that pulls settings from a database. Part of the setting definition is a regular expression that I want to use on the client via JavaScript for data validation...
1) Sample code for the setting object: ---------------------------------------------------- function setting(id, name, validationPattern, validationMsg) { this.id = id; this.name = name; this.validationPattern = validationPattern; this.validationMsg = validationMsg; }
2) Sample code on the page that creates a new setting object: ---------------------------------------------------- setting(1, 'test', '^d{1,1}$|^d{2,2}$|^100$', 'invalid value');
3) The issue: ---------------------------------------------------- The setting object gets built just fine except the pattern argument gets escaped by javascript!!!
^d{1,1}$|^d{2,2}$|^100$
GETS ESCAPED TO
^d{1,1}$|^d{2,2}$|^100$ (Notice how the double is now a single )
Is there any way for me to preserve the pattern text as is?
I want to validate the value in a textbox such that the first character should be a symbol like # or $ followed by 2 alphabets which is followed by numbers.I tried a pattern like code...
Im trying to find if a particular html markup pattern (<ROD> ... </ROD>) within a string and if its found then replace it with another string.eg."This is my string and it might <ROD>PartNumber123</ROD> contain HTML markup"So in this case I want to replace "<ROD>PartNumber123</ROD>" with {0}. If there is no <ROD>...</ROD> then dont do anything.Im sure im doing this the wrong way, maybe a regular expression would be best.Although this works its not very clean and I just cant find the correct solution.
function parseData(data){ var r1 = data.indexOf("<ROD>",0); var r2 = data.indexOf("</ROD>",0);
I am trying to do a pattern match and check something in a condition but cant get it to work. The first value changes and I need to check and do something if I get a hit on it.
Code: var mydata = "?first=one&second=two&third=three"; if (mydata.indexOf("first") == "something") { alert("No Hit"); } else { alert("Hit"); }
Basically I am trying to find out if first is equal to one in the mydata string. My above attempt is not working.
I need to validate three textboxes and it will validate for numbers. How should I change my code to validate three textboxes?
Code: Code: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
[code]....
I need to use Javascript to validate 3 textboxes, whereby the users can only key in numbers (because they are phone numbers related fields). If any of the textbox is empty, display an alert message to show which textbox is empty. I do not want to show many alert messages to show that, for example, text1 and text2 are empty, it will show two alert messages. I would need to show one "summarized" alert message instead.Next, check if the textbox matches the pattern (which is to check if it has the skeleton of a phone number). If it is, show an alert message that it is alright. Else, show that it does not match.
I need to test the contents of three fields to validate which contain text, and based on the results, set additional variables. I'm sure this is falling off the log simple, and I got it to work in PHP, but am having problems getting the syntax correct in Javascript.
In a nutshell, if a front AND a rear msg is entered, the price is $115, else the price is $80. I'm sure there's an easier way to code this than what I've done, but I don't know how to correctly perform several && and || in the same comparison.
Here's the PHP...
function notEmpty(){ var FrontMsgTxtTop = document.getElementById('FrontMsgTxtTop').value; var FrontMsgTxtBottom = document.getElementById('FrontMsgTxtBottom').value; var RearMsgTxt = document.getElementById('RearMsgTxt').value;
