JavaScript - Regexp Uri Hash

I was wondering if anyone could help me with regexp:

1)I would like it so that both a first and last name can be entered and that both ' and - can be included
2)I would like it so that addresses have to start with a number and then each word afterwards has to start with a capital letter and can include full stops, ' and -

Any help is appreciated!

Hello,

I have a the following text that I got from a getElementById and innerHTML and I need to get the model name from this text.

Code:

<div class="widgetWrap">
<div class="group1">
<h3><span>2010 Ford Escape XLT</span></h3>
<dl id="vPrice">
<dt>2010 Ford Escape XLT Prices</dt>

The last line has the year make model and trim level, I need to be able to get the model, "Escape" from here. The problem is the model does change, and I need to get whatever the model says, Focus, Expedition and so on. The make may change also, Lincoln or Mercury.

Is there an easy way to get just the model name whatever it may be?

I have been working on this for a while, and just can't get it.

Thanks for your help

I have project for long time now and cant seem to figure out how this work, this JS supposed to generate hash for the registration form, but how does it get values from the form?
Form has onSubmit="return( onPreCreateAccountSubmit() );"
----------------------------------------------------------
function onPreCreateAccountSubmit() {
doKtSubmit() ;

return onPreCreateAccount();
}
----------------------------------------------------------
function doKtSubmit() {

var ktlk = 'ktl';
var ktfk = 'ktf';
if (document.forms['createaccount'] &&
document.forms['createaccount'].elements[ktlk] &&
document.forms['createaccount'].elements[ktfk]) {
KT_preSubmit() ;
}

return true;
}

I have this string:

this is my test <a href="yay.html">yay</a>

and want to just match the part before the <a...:

this is my test

I can't figure out the regular expression for this. I've tried everything I can think of. It seems that it needs to do a non-greedy search on the first < it finds, but nothing works, like:

((.*<)?)

Please help, thanks!

hello all

I am working on a keyword filter and am stuck on something that I am hoping someone has more experience with

my problem is that I am trying to pass a regular expression as a variable to the RegExp() function in javascript but it does not seem to be working

example below

Code:

var X = '^(?=.*?(';
var Y = 'dog))(?=.*?(cat))(?=.*?(mouse'; // this gets created dynamically
var Z = ')).*$';

var A = X + Y + Z;
// result is ^(?=.*?(dog))(?=.*?(cat))(?=.*?(mouse)).*$ and is a valid and tested expression

var B = new RegExp(A, 'i');

I want to pass B to a search() function but it does not seem to be accepted as a valid expression anymore

thanks for any help

Hello there

I'm trying to build a simple little bot that you can ask questions. I'm using the indexOf method but I'm not sure if this is the best option for what I'm trying to do. If you type 'hello' or 'how are you' it answers. Any other input results in 'Dreadfully sorry but I didn't catch that. Say again?'. Is there a way that I can search input for certain words or combinations of words and trigger a single answer? Any help appreciated.

I have a situation where there is a string:
m0|18:+:m1|(-3)
which is a tracking method for preserving memory references
in the following string:
18+(-3)
In the user interface of the project I am working on; the user
changes the string to:
(18+(-3))*8
The object is to revise the memory tracking string to repersent
the changes. should be: (m0|18+m1|(-3))*8
Code:

//matches = this.getMemVals()
// getMemVals() searches the string 'm0|18:+:m1|(-3)' 
// with regex pattern to find instances of m#|#
var matches = new Array()
matches[0] = 'm0|18';
matches[1] = 'm1|(-3)';
var currentStateSaved = '(18+(-3))*8';
var glbs = '';
for(i = 0; i < matches.length; i++)
   {
    var matRegex = new RegExp(matches[i].substring(matches[i].indexOf('|')+1), 'g');
    alert('matReg: '+matRegex);
    glbs = currentStateSaved.replace(matRegex, matches[i]);
   } 
alert('GLBS: '+glbs) // <<< test code

The '18' part of m0|18 is not be found in the revised literal string
Why? (Has '18' been coverted to a number datatype?)

This is the type of problem that drives me up a wall and cost far to
much time trying to flush it out

Thanks of suggestions, advice

Code:

<html>
	<head>
		<script>
			function testemail(){
			var fld= document.getElementById("input1").value;
			var reg = /^[\w+]@[\w+].com$/i;
			if(reg.test(fld))
			{
				alert("email is ok");
			}
			else
			{
				alert("email is not correct");
			}

			}
		</script>
	</head>
	<body>
		<p>
			<form name="form1" onsubmit="testemail()">
				enter email : <input id="input1" type="text" /> <input id="input2" type="submit" value="Submit" />
			</form>
		</p>
	</body>
</html>

I am trying to test an email ID with above RegExp. I enter a correct email or not, I am always getting message "email is not correct" So RegExp is not working. How can I find out whats wrong with this RegExp ? Is there any tool to figure that out ? I tried with FireBug, but it does not point to whats wrong with RegExp

Thanks

I have been testing regex test string to match the following pattern
(- <any number with/without . decimal point>)
( -[#[.#]] )
here is the code that works the best:
Code:

var testStr = '99999+((-25.533) - 5)/99*(-25.533)';
var negValTestStr = new RegExp('\\(\-{1}[0-9]*\.?[0-9]*\\)', 'g');
var test = testStr.match(negValTestStr)
alert(test);

The question is: Why does it only work when the open and close
parenthesis are double escaped: '\\(' and '\\)'
When I use one backslash to escape, it will find -25.533, -5 and -25.533
With two backslashes for escape sequence: (-25.533), (-25.533)

Also, I have to escape the - to get just one -. If I do not escape the -,
-?; which should read - {0, 1} will match --# without escaping -

Thanks for thoughts on this

Hi all,

I am having some troule with searching a string taken from a text field (a name textfield, it's basically a form and the script is validating it).

I've been on the W3C schools website and I cannot get it to work, even with the "try it" feature.

Please help.

Code:

		function nameValidator(entry, msg)
		{
			var regExp = new RegExp("[a-z ]", "g");
			var s_regExp = new RegExp("[ ]");
			var tub = entry.value;
			var newLength = parseInt(tub.length);
			var i = 0;
			var space = 0;

			if (tub == "" || newLength > 20)
			{
				alert(msg + "entry must be > 1 and < 20 characters only!");
				return false;
			}
			else if (tub.match(regExp))
			{
				for (i=0; i < newLength; i++)
				{
					if (tub.substr(i,1) == "")
					{
						space += 1;
					}
				}
				if (space < 1)
				{
					alert(popup + "you must enter a space.")
					return false;
				}
				if (space > 1)
				{
					alert(msg + "you cannot enter a space more than once.");
					return false;
				}
				if (tub.substr(0,1) == s_regExp ||
				    tub.substr(newLength,1) == s_regExp)
				{
					alert(popup + "the first and last characters cannot be whitespace.");
					return false;
				}
                           }
                      return true;
                 }

1. Specifically, it will not correctly evaluate the statement where I've used the s_regExp variable nor will it detect white space at the space counter so it never increases (which the rest of the code relies on!).
2. What am I doing wrong. W3C states just also to use var newvar = new RegExp("\s") but that doesn't work, and I have even tried var newvar = new RegExp("^([a-z ])*$", "g") and that's useless too.

how about getting the attributes of the a tag? href and title and the innerhtml (actually the innerhtml has space on both ends)

Hey guys,

What is wrong with the following regular expression:

Code:

<script language="javascript" type="text/javascript">


document.write('\\Green Apple\\u003c\\\/a>'.match(/(.*)\\\\u003c\\\\\\\/a>/));

</script>

The ouput is: null
I am escaping each backlash but it doesnt seem to be working...

I am trying to get an alert when user type a digit in my textbox and i made this code:

<script type=text/javascript>
<!--
function allowed(){
var str=document.getElementById('firstname').value;
var patt=/[0-9]/g;
if(patt.test(str)){alert(not allowed);};
}
//-->
</script>
<body>
<input type=text id=firstname />
<input type=button value=Submit onclick="allowed();" />
</body>

But when i click the button then nothing happen. Please help me. Thanks.

Code:

<html>
	<head>
		<script>

		function dt(){
			var dt = new Date();
			document.getElementById("time").innerHTML=dt;
		}


		function changeBgColor1(){
				document.getElementById("bgc").style.backgroundColor='#ee0000';

		}

		function changeBgColor2(){
				document.getElementById("bgc").style.backgroundColor='#880099';

		}

		function changeBgColor3(){
				document.getElementById("bgc").style.backgroundColor='#888888';

		}

		function validate(){
				var a = document.getElementById("input1").value;
				var b = /[abcdef]/;
				if(b.test(a)){
					return true;
				}
				else {
					alert("invalid character");
				}
		}
		</script>

		<style>
			#bgc{
				width:300px;
				height:100px;
				background-color:#cccccc;
				font-weight:bold;
				color:#ff00ff;
			}
			#time{
				width:300px;
				height:50px;
				background-color:#aabb00;
			}
		</style>
	</head>

	<body onload="dt()">
		<p id="time"> </p>
		<p  id="bgc" onmouseover="changeBgColor1()" onmouseout="changeBgColor2()" onclick="changeBgColor3()">
			Hi There, pls change bg color
		</p>
		<form id="form1" onsubmit="validate()">
			<input id="input1" type=text />
			<input id="input2" type="submit" value="Submit" />
		</form>
	</body>
</html>

validate function does not work with IE or Firefox, it always returns true, even if some digits are entered in input box (which should not be validated by regexp). Why does regexp not work ? How to make it work ?

Thanks

Hi All

I'm using the fantastic turtorial here for my site navigation:

http://css-tricks.com/6336-dynamic-p...acing-content/

It's all working wonderfully but I've hit a major stubmling block. After the new page is loaded it won't load an scripts. E.g. I'm using scripts for expanding divs, galleries, contact forms etc and they simply don't run after the page transition

Let me know if you need a link to my project

I'm aware the page isn't actually 'refreshed' so I'm asuming they wont fire the standard way by having the script tags in the header (Please correct me if I'm wrong) So my question is how can I get them working once the new page is loaded?

Script below:

Code:

$(function() {

    var newHash      = "",
        $mainContent = $("#right"),
        $pageWrap    = $("#wrap"),
        baseHeight   = 0,
        $el;
        
    $pageWrap.height($pageWrap.height());
    baseHeight = $pageWrap.height() - $pageWrap.height();
    
    $("nav").delegate("a", "click", function() {
        window.location.hash = $(this).attr("href");

                                height: baseHeight + $mainContent.height() + "px"
                            });
                        });
                        $("nav a").removeClass("current");
                        $("nav a[href="+newHash+"]").addClass("current");
                    });
                });
        };
        
    });
    
    $(window).trigger('hashchange');

});

All help is appreciated
Thanks in advance
