Regular Expressions Replace - Detect The Number "2" And Put It Superscripted Past The Number 5

Jan 3, 2011

Formerly I've been replacing characters with javascript using the following code.

paramString = paramString.split("").join("<sup>");
paramString = paramString.split("").join("</sup>");

So if the user on my website types 52 it would return the following value: 5<sup>2</sup>, or just, 5 how do I detect something like this. if they enter: 5 how can I detect the number "2" and put it superscripted past the number 5. so the javascript reads this: 5 and returns this: 5<sup>2</sup>

Regular Expressions - Detect Letters In String?

Mar 2, 2011

I'm trying to make a script which will check if the string which the user sent from a form contains ONLY letters. The problem is if the user entered something like this "25 years old" it allow that to be submitted. It only blocks submissions of the form if the user submits NO letters like this "12345". I want it to block submissions if at least one character isn't a letter. Here's my code:

var message = document.myform.formtest.value;
var allowed = /[A-z+]/;
if(!allowed.test(message)) {
alert("The field only allows letters (a-z).");
return false;
}

Find And Replace A Number

Feb 12, 2011

When I find a record such as this in a textarea:

[Code]....

There will be from 1 to 4 Pts, if one is missing there will not be a next one. My problem is I replace the first occurrence of any number I find and for certain factors (2 in this case) it could change an already converted number and leave other fields in the record alone. I could split the line on commas to change the first number I find but can't be certain if there are no other commas elsewhere on the line.

Script For Counting A Number - Want Down To Another Number That Resets?

Nov 28, 2011

I am trying to figure out how to make a random number I can plug into a script count down from that number at certain times of the day until it reaches 0. I would like it to reset itself at midnight every day. I'm trying to make it work with a script I found on here that resets itself at midnight every day. So instead of it counting down too fast, it would count down to the next number after a randomly generated number of minutes until it reaches 0. But it wouldn't necessarily have to end at 0 at midnight. It could go from 845 to 323 at the end of the day at a slower pace. Is that possible?

Regular Expressions Challenge

Jul 23, 2005

Coding patterns for regular expressions is completely unintuitive, as far
as I can see. I have been trying to write script that produces an array
of attribute components within an HTML element.

Consider the example of the HTML element TABLE with the following
attributes producing sufficient complexity within the element:

<table id="machines" class="noborders inred"
style="margin:2em 4em;background-color:#ddd;">

Note that the HTML was created as a string in code, and thus there are NO
newlines ('
') in the string, as if a file was parsed...so newlines are
not an issue. The only whitespace is the space character ' ' itself,
required to delimit the element components.

I want to write an RE containing paranthesized substring matching that
neatly orders attribute components. The resulting array, after the
execution of the string .match() method upon the example, should look as
follows:

attrs = [ "id", "machines", "class", "noborders inred", "style",
"margin:2em 4em;background-color:#ddd;" ]

I can then march down the array (in steps of 2) setting attributes
(name=value) to the element using standard DOM interface methods, right?

In approaching the writing of the RE, I have to take into account the
characters permitted to form the attribute name and the attribute value.

I assume a start to the RE pattern as:

<attribute name>=<attribute value>

I then try to find the right RE pattern for <attribute name>, keeping in
mind what the legal characters are for attribute names according to the
HTML standard ("recommendation"):

[A-Za-z0-9-]+

I believe this patterns conforms to the standard for attribute values:

[,;'":!%A-Za-z0-9s.-]+

That pattern tries to be more exclusive than inclusive, although I think
just about every character on the planet, including a newline, is
acceptable in an attribute value, at least the kind one might see in an
HTML document. Code:

Regular Expressions In JavaScript

Jun 3, 2001

I am trying to use regular expressions within JavaScript for the picture upload component of a shopping cart. I still can't seem to get my mind around them.

I have a page with a working file upload. When you click on browse and then select your file, the file name is also returned to the second field, the picture name field. The problem is that the entire string is returned - 'G:CatalogMyPicturessomepic.jpg' instead of 'somepic.jpg'.

I know this can be pulled out with regular expressions, everything from the right until it hits a / or I included the script and a couple of links. Code:

Form Verification Using Regular Expressions?

Mar 4, 2011

i'm trying to use a regular expression to verify an order. I basically don't want any decimals or negative numbers allowed. I believe I have any digit 0-9 one or more times and negating decimals. but for some reason it allows decimals and letters. also is it correct to put return true or can i just leave it blank?

var varifyThree = /^\d*[^\.]$/;
var productThree = document.getElementById('prod3').value;
if (productThree==null || productThree=="" || varifyThree.test(productThree)) {
return true;

Form Verification Using Regular Expressions

Mar 7, 2011

I keep getting an error that says item is null. I'm a little lost because once I got my regExp to start working this actually worked for a little bit. When I came back I was getting an error.

var creditExp = /^([345])(\d{3})\-?(\d{4})\-?(\d{4})\-?(\d{4})$/;
var creditNumber = document.getElementById("creditnum").value;
var item = creditExp.exec(creditNumber);
document.getElementById("creditnum").value = item[1] + item[2] + "-" + item[3] + "-" + item[4] + "-" + item[5];
if (item[1] == 4 && document.getElementById("card1").checked == true) {
return true;
}else
if (item[1] == 5 && document.getElementById("card2").checked == true) {
return true;
}else
if (item[1] == 3 && document.getElementById("card3").checked == true) {
return true;
} else {
alert("You must enter a valid credit card number.");
document.getElementById("creditnum").focus();
return false;
}
var billingName = document.getElementById('creditname').value;
if (billingName == null || billingName == "") {
alert("You must enter your first name as printed on your credit card!");
document.getElementById('creditname').focus();
return false;

Macintosh MSIE And Regular Expressions

Dec 27, 2005

Here's what used up the last couple of hours of my time.

The Mac version of MSIE will not load a script that has this in it:

theItem.elm.value = theItem.elm.value.replace(/^s*(.*?)s*$/, "$1");
Now I had other regular expressions in the script done this way, but in this one case I had to use the object constructor method.

It will won't work in this browser, but now at least the script loads and other functions in the same file work.

I have a solution so basically I'm looking for some insight into this if anyone has it. What is it about this particular expression that upsets Mac MSIE?
