Search For Element Using A Pattern
Nov 10, 2011
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.

I have a search field on the website, and when I type a word to search, it search good, but after preforming the search, the search term from search text field disappears and become the default 'Search' word.
How can I make search term stay in search field after preforming a search ? For example, when I type into the search field 'JavaScript' I want that term to stay in search field and after the search is done.

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'm currently doing a javascript course and am working on my coursework, I've come across a roadblock.
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?

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.

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);
}
}

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]">
<!-- Exercise 7.25 Solution -->
<html xmlns = "[URL]">
<head>
<title>Solution 7.25</title>
<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>")
-->
</script></head><body>
<p>Click Refresh (or Reload) to run this script again.</p>
</body></html>
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.]

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
