JQuery :: Finding/selecting Items Identified By An Attribute Whose Value Contains Quote Characters

Jul 2, 2009

I am writing a test harness for a web app using jquery. When recording a test, I add handlers for user interaction events (e.g. click on an A tag), and record details of the tag clicked. When playing back, I need to find the tag (so I can emulate a click on it). The A tags do not have id elements - the only unique way to identify then is to use the href. However, I have hrefs containing quote characters [typical hrefs include "javascript:Go('fred')" and even "javascript:Go("jimmy's ")"]. How do I construct a jquery selector to match these?

My first attempt (before I noticed the presence of the quotes) was

$("A[href='" + href + "']")

Interestingly, this hung the browser completely for many minutes!

Finding A Number In String - RegExp

Aug 13, 2005

How can I check if a number exists by itself in this string by using
the RegExp object?

var mystring = "11,111,01,011";
var match = "1";
var re = new RegExp( match );
var isFound = re.test( mystring ) );

Running this code returns 'true' which is not what I want since number
one doesn't exist by itself. I need to use the "match" variable since
it will change depending on user input.

I can only get it to work without variables in the expression. E.g.

var re = new RegExp( /1/ );

Removing Characters From A String?

Oct 1, 2011

So I've got an array called questions_raw

questions raw = [
["<Q1> Question",
"choice1","choice2", "choice3"],
["<Q2> Question",

[Code]....

And I want to list all of the questions, but not the choices/answers. So far, I've managed to list just the questions, but because another function randomly sorts them, I need to sort them back into numerical order for a separate function (displaying the questions)

I use characters (>,^) at the front to separate them into different answer types (just to explain the code)

I try this to cut each string down so that they can be sorted numerically/alphebetically -

function linearlist()
{
var list = [];
var tempStr = "";

[Code]....

But it doesn't like it - because "it has no method charAt"

Is it just that you have to put the [l] in every time you call a variable?

Replace Whitespace Characters In String

Oct 12, 2005

I have a JavaScript string. I want to replace all consecutive
occurrences of whitespace characters like spaces, tabs, newlines, and
form feeds with another string.

For example, say I have a string consisting of:

-- 3 spaces
-- The characters "hello"
-- 2 newline (
) characters
-- The characters "goodbye"
-- 5 spaces

After applying some sort of regular expression to replace consecutive
occurrences of whitespace chars with the string "X", the string should
consist of the following:

-- The character "X"
-- The characters "hello"
-- The character "X"
-- The characters "goodbye"
-- The character "X"

How could I do this using regular expressions? I'm quite familiar with
JavaScript but don't know anything about regular expressions or using
them in JavaScript, so please show me step-by-step how it's done.

JQuery :: Possible To Replace String Characters?

Aug 4, 2009

I am running a search on my web site which uses jQuery to take the search terms and build up a URL based on them. For example, if someone searches for "chair" my URL will be appended with /chair/. However, if someone searches for something which is two words, for example "chair covers" I need the space in between to be replaced by a "+" sign so the URL will now be appended with /chair+covers/ I'm not sure if it is possible to string replace in jQuery?

Here is my current code:
function sendSearchInput(whichelement,hiddeninput,formid) {
hval = $("#"+hiddeninput).val();
$("#"+formid).submit(function() {
if ($("input:#"+whichelement).val() != hval) {
var searchval = $("#"+whichelement).val().toLowerCase();
$("#"+formid).attr("action","retail/search/"+searchval+"/");
return true;
}
$("input:#"+whichelement).focus();
return false;
});}

This will basically check that the form is not the default value (specified in the hidden field "hval") and then change the search term to lowercase and append the URK using "attr". I have tried a couple of methods including
var test = searchval.text().replace(' ','+');
And then trying to alert "test" to check it but the function just simply doesn't work.

Check Last 15 Characters Of A String For A Space/tag?

Jun 27, 2011

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

Inter Space Characters Within String?

Jan 22, 2010

This may seem like an odd question but I was wondering if there was a way to use javascript to dynamically inter space characters in a string with other characters.

Basically i would want to take this:

"This is a string"

and replace it with this:

"T.h.i.s. .i.s. .a. .s.t.r.i.n.g"

I know it seems strange but I have my reasons

Search In Array Or String For Individual Characters?

Nov 3, 2011

I'm writing a piece of JS code that returns a result of true if the pattern appears in string as a substring (case sensitive) but would like to extend its functionality to returns true if all the individual characters of pattern appear in string (regardless of order).

For example:This is what the program currently does:

match1("adipisci","pis") returns true

Whereas I would now like it to do this:

match1("adipisci","sciip") returns true
match2("adipisci","sciipx") returns false because x does not exist in variable
match3["adipisci","adipisci"] returns true in array 1 and 2 if "sciip" is searched
match4["adipisci","adipiscix"] returns false in array 1 and true in array 2 if "sciipx" is searched

I am having difficulty implementing this into my code... this is what I've done so far:

var pages=[
"Lorem ipsum dolor sit amet, consectetur adipiscing elit.",
"Nulla imperdiet laoreet neque.",

Regular Expression - Enter A String That Is 2 - 20 Characters Long And Only Has Letters Doesn't Work

Jun 28, 2010

I wanted to try creating a basic expression first. I want someone to enter a string that is 2 - 20 characters long and only has letters. This is what I use so far, and it doesn't work, nothing happens at all when I run it.

Code:
// Check for a valid name.
var namePattern = new RegExp("/^[a-zA-Z]{2,20}$/");
if (namePattern.test(name))
{
window.alert("Invalid");
}

name comes from a input box I display on screen. Also, I would like to update the expression so that there can be one space in the string, but it cannot be at the beginning or end. So this string is like a persons name. Bob is OK, Bob Smith is also OK. Edit: Actually, it is doing something but its always coming back invalid.
