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.
[Code]...
I am trying to make an application that displays a pattern of asterisks a certain way. the only output statements I could use are to get the pattern below. My question would be which way to use the nested loop, (do i do while(if else)...
[Code]...
This code not sure what the final result should be.

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 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?
function checkTime(pattern){
if(pattern.value.match(/[0-9] + :[0-9] + [0-9] + [aApP] + [mM]/)) {
alert ("works")
}
else alert(pattern.value + "Does not work")
}
I am trying to use a string for a regular expression pattern. Here is a
test that I set up:
var s="^d{3}-d{3}-d{4}$";
var r=new RegExp();
r.compile(s);
var t="333-333-3333";
alert(r.test(t));
I have tried this with and without the "compile", and also adding the
"/..../" to the beginning and end of the string, but I always get "false".
Can you use a string to represent a pattern...in Javascript?
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.

Part of the task is to create a pattern match to recognize valid postcodes.[code]...
At a minimum, I'd like to know the official term for what I'm trying to do is called, then I can at least do some reasearch on my own.
While I'm here, how's my coding so far? Anything that screams "bad practice"? or "I could do better"?
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 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.
Two fairly basic questions:
I need to supply a method with an array of strings, which will
eventually be used to pattern match against another array of strings.
1. Is there a good way to span multiple lines when creating an array
from a list of strings? (I want the most readable list I can get.)
// The following doesn't seem to work
urlExclusions = newArray(
"my.domain.com/dir1",
"another.domain.com/dir2",
"third.domain.com/blah"
);
2. When I'm looping over the above array in a method, what's the best
way to use these as patterns to match? Does "new
RegExp(urlExclusions[i], "i") do all the necessary escaping of
whatever literals might be in the urlExclusions[i] string? (All
characters in the above strings should be treated as a literals. I
don't intend for that list to be a place to put RegEx.)
Example: I want to do something like this with the list:
for (var i=0; i < urlExclusions.length; i++) {
pattern = new RegExp(urlExclusions[i], 'i');
if (pattern.test('http://my.domain.com/dir1')) {
document.write("Matched");
} else {
document.write("Didn't Match);
}
}
Code JavaScript:
/(?:[^\]|^)(//.*)$/gm
It checks that the character before the comment isn't a backslash or that we're at the start of a string/line since it's in multi-line mode. Then it captures the actual comment. Seems to work so far... I have the following RegEx that matches double slash comments:
Code JavaScript:
///.*$/gm
It works fine except for this one exceptional case where a RegEx which ends in a slash is followed by a comment as in the following example:
Code JavaScript:
//*[sS]*?*//gm, // Slash comment
The RegEx captures "//gm // Slash Comment" as a comment, removes that piece, and in the process breaks what used to be a valid RegEx statement. how I might be able to fix the pattern to avoid this issue?

I wanted to only match in the middle of a string
I have a string = " sdfasf 23234"
I wanted to get the numbers like /([0-9]*)/
But this fails and returns nothing because the string begins with letters. Instead I had to do /[a-zA-Z ]*([0-9]*)/
If that's the case then, why do we bother with something like
/^[a-zA-Z]*([0-9]*)$/
The pattern is already assumed to start at the beginning of the string
I need to parse an an HTML page and pull what ever values are in these JavaScript tags. There will usually be multiple tags with different values between the single quotes. The value in the next example I need to pull into my array would be 'A728'. Here is an example code..

I really can't figure out why it's not working in IE. The only problem I can think of would be using nested loops. Here's the part of the code that isn't working. It's not generating an error, it's just not returning anything. I know you guys hate when I post entire code, so I trimmed it down as much as I can. It's referring to an already stated xml document with xmlDoc. And it's goal is to return a table of rows that meet certain criteria. If you can see any syntax errors that explorer would not like, that's really what I'm asking for.

I have to create a pyramid with nested for loops in javascript. This wasn't a problem until my professor asked us to mirror the pyramid. this is the code i have so far:
<script>
This part of the program works. What I'm having trouble with, is placing spaces and x's on the left side so that the triangle appears like:
I saw a few thread that had the right half of this triangle upside down, but I couldn't figure out how to flip it and fill in the other side. I'll attach the .html file so people can run what I have so far.
I'm having trouble getting this nested loop to work. It only outputs the last image and I want it to loop through the images.

I have 4 text boxes that are supposed to load 4 seperate values of data from one field in one table from a database. The field is called interface_cropsettings (from the interface table) and these values have been concatenated and comma seperated in this field.
Code:
Once the form is filled out and saved, the data is inserted into the database and the values from these 4 text boxes are concatenated, comma seperated and inserted into that one field correctly.
(Example)
If the 4 text boxes have the following values:
In the database field they become:
However, if the form is closed and then re-opened, each text box displays the entire database field rather then each value seperated in the corresponding text box.
(Example)
All 4 text boxes display this:
I already know why the data appears like this in the form, my problem is that I'm not sure how to write the javascript to seperate the values into the correct corresponding fields, assuming javascript is what I should be using!

I have just found this wonderful forum through Dr Google whilst looking for an answer to my incredibly frustrating question! I am an OU student it is for an assignment I just cannot find the answer in any of the books and searching the net has got me nothing but so far wasted 3 hours :(
Here is the code snippet:
First I had to add a new array called totalVotes and assign a length to it the same as candidateArray, I have done this in the last 2 lines I think this is correct, the question did stipulate that if the candidate array was changed then so would the total votes array hence linking it via length.
Now here is where I am at a complete loss :( The exact wording is as follows:
Use a for loop to calculate the total votes for each candidate according to the following structured english:
For each array position add the element at that position in the online vote array to the element at the position in the paper vote array. store the result at the corresponding position in the total votes array end for.
