I have a string I have to parse
AB1.2CD34
I need to split the string into groups of letters and numbers..
"AB" "1.2" "CD" "34"
What is the best way of doing this ?
I've looked at string.split using a regex, but that doesn't output the
delimiters.
From this string: "(EVAL)(H:somestring)Other Text here"
I need to extract (H:somestring) and somestring into variables where somestring will could be and set of characters. Below is not working.
<script type="text/javascript">
var x = "(EVAL)(H:pines)Some other Text here";
alert(x.match(/H:(.*?)/g));
</script>
trying to search thru a string that's delimited by '|'.
would like to iterate over each one in the list
var teststr= "|aaa|bbb|";
var re = /|(.*)|/g;
var results = re.exec(teststr);
if ( results != null )
{
for ( var i = 1; i < results.length; ++i )
alert("[" + results[i] + "]");
}
would like to see 'aaa' and then 'bbb'

I would like to strip HTML out of a string I have in a JSON item I have. I'm using Yahoo! Pipes to aggregate several blog-feeds and put them in together in one big feed, I then use jQuery to parse that JSON and place it onto my page. My issue is though that what's being parsed onto my page is the raw html code within the JSON item. I want any HTML related tags out of the item, so I just see text.

Why doesn't it recognise it and how do i fix my problem?
I have a simple example below showing how when I pass in the value of the value attribute of option node, and then use if operator to check whether parameter is a string or not, even though it's a string, it converts it to false boolean and triggers the else statement rather than calling a function.callback should be a string so why is it saying otherwise?

How to check if some char in textbox contains one of the ones in string "allowedChars"
I need Regex to find all the following:
http,https,ftp,news,file
With a case-insensitive search, and then I need to convert to URL safe string i.e. %2E%2D etc
This is about as far as I got:
Code:
String.replace(/http/gi,"")
Not very strong with Regex.
i need a check that can go through a string to see if it contains any numbers.

I have thought about using the standard email checker pattern but we have had problems in the past so looking to check if the string follows these simple rules.
has no spaces, has a character/s at the start followed by an @ then has a character/s followed by a (dot) then another character/s
i.e
a@a.a
aa@aa.aa
aaa@aaaaaaaaa.aaa
i am not sure how the standard pattern works but feel that it may be to complex which causes some email address to fail.
So I want to be able to check the last 15 characters of a string for either <br /> or a space. I know how to do this with PHP but I have no clue how to do this with Javascript and Google is failing me. Could someone point me in the right direction?
Example string: var string = "Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat."
I'm assuming this will be done with lastIndexOf but I do not know how to do it. So to reiterate, I want to check to see if either a space exists, or <br />, delete everything after that, and return the string. So the output of the example string would be...
Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo
I was just wondering how to go about checking the content of a string to see if it matches a set criteria?
For example, if I want to make sure somebody enters a date as mm/yyyy, how do I check to ensure there are:
2 numbers between 1 and 12 before the /.4 numbers between 2005 and 2020 after the /.And that the / appears between the two. I know in PHP you would use a regular expression, but how do you do it in Javascript?
I am trying to check for Arabic characters in a string using Regular expressions. This should return true, as the string in the str variable is indeed Arabic character. But it returns false.
View 2 Replies View RelatedI 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 want to check if the user enters alphabet or numbers only in the
text box. If the user enters non-alphabet or non-numbers, I should pop
up a message and doesn't allow the user to do that. I am using regular
expression to do the checking. But it seems it always return false...
Looking to return true if a question mark (?) exists in a given string.I was thinking of something like the following, but it obviously doesn't work.
alert('/?'.test('my?string'));
Ive just started to learn JavaScript, and I have trouble to write JavaScript code which checks a string to contain at minimum one uppercase letter, one lowercase letter one number and one special character with no white space allowed.

View 10 Replies View RelatedHere is the HTML: [URL] I'm trying to uncheck the selected radio button, then set the value to 1 (Yes), basically overwriting theinitialvalue to 1. I've looked at prop(), val(), and attr(), and just don't know where to start. Should I select $('#set_q157 input') or$('#set_q157 input:radio'), or each individual radio?
Do I need to each them, and check if its checked, then change its value, or is there a way to select all three inputs as just one radial button? It would also need to work if the input has not yet been checked.
i have a list of checkboxes, the number of checkboxes is dynamic. All the checkboxes have same name. i am trying to get the length of selected checkboxes.
<input type=checkbox name=name1 value=1>
<input type=checkbox name=name1 value=2>
........ get dynamically.
when i try to get the length in javascript like document.form.name1.length, it works fine if number of checkboxes selected are more than 1, but not for 1.
I have a code that I got from a tutorial website. The goal is when someone clicks the first check box with the value of yes then the two other sets of check boxes will autmatically be checked for no.
The issue is their are three sets of 2 check boxes each.
So here is my code code I am trying to use
PHP Code:
Here is my form code
PHP Code:
So Ideally when a representative clicks that the customer has three services (clicks the Yes checkbox) all the other checkboxes will default to No.
How I would change the above javascript to do this.
I am a php programmer and not a Javascript programmer and I am trying to help a friend out with his shopping cart. The original programmer (who wrote this years ago and is no longer around) has a button that looks up the quantities in the database for the submitted items, and then displays a prompt if you selected a quantity that is less than the minimum purchase amount.The issue is if the user enters a smaller amount than allowed and hits the enter key instead of the "Buy" button, it allows the order.how to use the current code to also check for an Enter key submission.I can handle the PHP and the db lookup for minimum quantities. Here is the page code and the Javascript code.
Code:
<a href="javascript:checkQuantity(document.form<?php echo $formCount; ?>,
<?php echo $row_rsProduct['lotQty']; ?>,

I have an .asp page for my customers which does just accepts e-mail information and passes this information to another .asp page. But before passing the info, a javascript checks whether the entered e-mail does match some certain rules. Rule1: If any input has been made at all, Rule2: If an "@" sign is there, if the"." is there and so on. upon pressing the submit button, the first rule works but the second rule does not. Could not figure it out why.
[Code]...
It is the function control() which validates the e-mail field. But it just validates whether the e-mail has been entered or not. The second check (with the @ sign) is not being made.
