JavaScript - Regex: Find Ampersands But Ignore Html Entities

Hi there,

Im a total newbie and learning html and javascript as I go along, so any help you can give is greatly appreciated!

It is possible to perform a find in page search that looks at a specific link, opens the page in a new window and finds the text within that document??

Basically I regularly use an html page in work that has a list of people and their telephone numbers.

I want to be able to type in a searchbox on my main page and it open the target page and find the name I am looking for?

Is this possible or can you only Find In Page on the same page or another frame?

Tearing my hair out........

Thanks
Glen

Hi,

I'd like to use the jQuery validation plugin as seen on the following example:
http://docs.jquery.com/Plugins/validation#Example

But it doesn't work properly if I use inline/in-filed labels.


Any help is appreciated!

I frequent a forum that has a pretty large community. There are a few users there I don't particularly care for. I would like to make a Greasemonkey compatible javascript code that would allow me to completely erase their posts from the page.

What I want to happen is that every time
Code:

<li class="kpost-username">
			<a rel="nofollow" title="" href="/index.php/component/kunena/profile/userid-80?Itemid=0" class="kwho-user">Rolepgeek</a>		</li>

appears it deletes the parent <table class="kmsg"> node.

I know that I can find each of those code snippets with Code:

document.getElementById('kpost-usernmae')

however I am not sure how I would go about defining if it includes Code:

<li class="kpost-username">
			<a rel="nofollow" title="" href="/index.php/component/kunena/profile/userid-80?Itemid=0" class="kwho-user">Rolepgeek</a>		</li>

or not, nor am I sure on how to tell the code to delete the parent <table class="kmsg"> node when it does include it.

I've been messing around a bit with some code, and I understand the general idea of how it should work, however I do not know the syntax in order to get it to work. Any help would be appreciated.

Code:

<table class="kmsg">

Hi,

Does anyone know how to make a javascript regex ignore new lines?

I have this
Code:

html = html.replace(/<!--(.*?)-->/gi, '');        // HTML comments

which matches single line comments like -
Code:

<!-- this is a comment -->

but not this -
Code:

<!--
This is a comment
on multiple lines
-->

I think the answer lies with [\s\S] but I can't get it to work

e.g. -
Code:

html = html.replace(/<!--(.*[\s\S]?)-->/gi, '');        // HTML comments

Any help will be greatly appreciated

Cheers Al

I have this code so far;

PHP Code:
        validatePhone : function(field, caption) {
            phoneNumber = /^[0-9]{11}$/;
            if(phoneNumber.test(field.val())) {
                return true;
            }
            return i18n('phone', caption);
        }, 


It works fine for entering an 11 digit number. However, I want to check that the number starts with either 077, 075, 079 or 078. Also, if the field is empty then it can also be accepted. How would I do this? Thanks

Hi,

I'm using this site Translator Editor - LingoJam
I'm trying to use the regex portion of the site (click regex on the page that link goes to) to create a substitution cipher - a translates to o, etc.

so far I have

Code:

/a/g -> o
/o/g -> u

Theoretically, that'd mean when I typed in "a", it would translate to "o", and when I typed in "o", it would translate to "u".
Trouble is, it doesn't know when to stop. I type in "a" and it immediately returns "u", because it substitutes the "o" that it should end up as for the "u".

Any help on this matter would be appreciated.

Thank you.

That is bound to occur if you use onkeyup to translate the letter immediately it is typed. You should create the cyphered text once the whole message is complete.

All advice is supplied packaged by intellectual weight, and not by volume. Contents may settle slightly in transit.

I am creating a userscript and trying to take the following:

Arian Foster (Hou - RB)

and end up just with the team name:

Hou

You can't remove by index (which I would be able to do), because it might be K instead of RB or NO instead of Hou. I am assuming that you use Regex and the replace function to do so, but I am struggling with understanding all Regex symbols. Can someone help me with this and explain it briefly? I would appreciate it.

Should alert '' twice , instead alerts original text
Code:

      text = 'p18=100';
      text = text.replace("(^|&)p100=18.*?(&|$)","")
      alert(text);
      text = text.replace(/(^|&)p100=18.*?(&|$)/g,"")
      alert(text);

tested regex on online tester and it should be OK.

?

i'm trying to make a validation page and i am having issues with some of them

AGE - i'm not sure where to go from here
Code:

var age = /^[0-9 ]{3,20}$/;   // trying to check age (only 18-25 is valid)

Name - how do i make it so that no spaces are allowed?
Code:

/^[A-Za-z ]{3,50}$/

street - i have no clue where to even begin on this. i think that RegEx can't be used to validate all addresses, but something simple like 123 main street. maybe something like this Code:

preg_match('/.{2,60}$/',$address)

here's an example of my zip code one to give you an idea of what im going for
Code:

function checkZip(){
var re5digit=/^\d{5}$/ //regular expression defining a 5 digit number
if (document.myform.zip.value.search(re5digit)==-1) //if match failed
alert("Please enter a valid 5 digit number inside form")
}

HTML FORM
Code:

<form name="myform" onsubmit="return checkZip()">
		<fieldset>
		<legend>Test Form</legend>			

		Firstname*: <input type="text" name="firstname"/><br/>
		Lastname*: <input type="text" name="lastname"/><br/>
		Street*: <input type="text" name="street"/><br/>
		City*: <input type="text" name="city"/><br/>
		State*: <input type="text" name="state"/><br/>
		Zip*: <input type="text" name="zip"/><br/>
		Age*: <input type="text" name="age"/><br/>
		Gender*: <input type="text" name="gender"/><br/>
		Major/Program Choice*: <input type="text" name="major"/><br/><br/>
		<input type="reset" /> 
		<input type="submit" />

what is a good way to combine these into all one function using getElementByID? i could make another function and put all the other functions in it, but i'm not sure where i can incorporate getElementByID

when the verification is complete, i want to display all the info using getElementByID and innerHTML. should i make vars that hold all the info and put in after a span somewhere?

Hi All, i have this Regex which is below and im trying to validate a field when a button is clicked

i may have this mest up but what the regex does it checks for 1 decimal place and returns true or false i put some comments in with the code

Code:

function IsNewBid() {
    var NewBid = document.getElementById('MainContent_txtNewBid').value;
    var result;
    result = ^[0-9]{1,10}[.]{1}[0-9]{1,2}$|^[0-9]{1,10}$(NewBid .Value)
    if (result 'Equals False So theres and error')
        Do something
    else{
        carry on 
      }
        
}

Any help will be highly appreciated..

Thank you for your time.

The following code works as required -

Code:

if (result.marc.f695.subfields['a'] != "Electronic journals" 		
  && result.marc.f695.subfields['a'] != "electronic journals") {
          return;
}

However, this isn't the most efficient way to code it, especially as I want to add further possibilities, most beginning with "[Ee]lectronic. I know I need to use regexes, and think the code I need to use is something like /[Ee]lectronic/, but I use JavaScript so rarely that I'm not sure how to build this into the above expression. Can anybody help?

I am trying to run a simple replace over some css a user puts into a textarea. I would like to remove all the comments

Code:

/* MY COMMENT */

I have tried the following to try and escape the forward slashes but to no avail.

Code:

replace(/\/*(.*)\//g,"");

any ideas?

Thanks!

Hi - I am trying to use this code to validate,

function test() {
var pattern = (/^\d{3}[-]?\d{2}[-]?\d{4}$/g);
var pattern1 = (/^d{3}$/g);
if(!pattern.test(document.myform.textInput.value)||(!pattern1.test(document.myForm.textInput.value)) )
{
alert("Error!");
}
}

using regular expressions to compare a string from an input with two patterns that could both be valid. Therefore I'm pretty sure I need to use "||" between them both. I can't quite figure out how to get javascript to check for both patterns, only the first seems to be checked as valid. Is it something to do with the way I have my brackets?

Can someone point me in right direction,

Thanks

Hey everyone, I'm working on a script, but I've been stopped by an error code from regex's match function. Firefox is giving me a "text.match is not a function". My assumption is that it may be the getSelection that is causing the error. Any clarification would be much appreciated!
Code:

function captureText(){
	var txt = "";
	if(window.getSelection){
		var text = window.getSelection();
	}
	else if(document.selection){
		var text = document.selection.createRange().text;
	}
	else {
		return;
	}
	if(text != ""){
		var reg = /^[A-Z](.*?)+(\.)$/g;
		var check = text.match(reg);
		alert(check);
		alert("You selected: "+text);
		if(window.getSelection){
			window.getSelection().removeAllRanges();
		}
		else if(document.selection){
			text.blur();
			document.selection.empty();
		}
		else {
			return;
		}
	}
}
document.onmouseup = captureText;

Thanks.

Hello, I have this piece of code I read from a book to remove text nodes that only have white space.

Code:

if (node.nodeType == 3 && ! /\S/.test(node.nodeValue)){
   // code to remove the text node
}

Why should we use this:
Code:

! /\S/.test(node.nodeValue)

Instead of this?
Code:

/\s/.test(node.nodeValue)
