im trying to convert a string into arrays in javascript using split() function.
how to i split a string using spaces as a dilimeter but ignoring spaces enclosed by double quotes. ie: john robert "peter rabbit"
I want to get the sum of all numbers in an text area irrespective of the spaces before between or after them. e.g. " 1 2 12 15 " =30
In the code below I can have multiple spaces or CR between numbers and it works giving me their sum But if i have a space before the first number or after the last number I get a NAN (

how does document.write interpret "" and '' (double quotes and single quotes).what is the significance of &Url (does it signify the current url) colon : is it represented as %3A ? and backslash represented as %2F ?
View 1 Replies View RelatedI've got this bit of code that I've wrote and it was working absolutely fine like this:
function validatepostcode() {
var postcodevalue = document.getElementById("postcode").value;
if (postcodevalue.indexOf("S") == -1)
{
alert(postcodevalue + " is not a valid postcode.");
[Code]...
What I want to do is wrap the value of "postcodevalue" in double quotes, and since it's inside an alert, I used the escape sequence ", which is how it should be done as far as I know. But for some reason, Dreamweaver's giving me a syntax error warning and the code doesn't work. Am I using the double quotes wrong?
I have completed the necessary function and it does not need any changes however from the "alert" I need there has to be double quotes surrounding the search 'Lboro'. (I know I may be making a meal of the coding however the lecturer wants us to follow this due to everyone being at different levels of programming). I have used the '' character however the double quotes do not end up in the position I require them?!
My Coding
function findAnyU (s){
var a = s , b , c , d , e = -1;
for (var i = 0 ; i < pages.length && e == -1 ; i++){
b = pages[i].indexOf('[');
c = pages[i].indexOf(']');
d = pages[i].substring(b+1, c).toLowerCase();
e = d.indexOf(s.toLowerCase());
}
if(e >= 1)
a += ' found'
else
a += ' not found'
return (a)
}
alert (findAnyU('Lboro' , pages));
Current Alert =
Lboro found
I have the following PHP which passes a variable to two other frames:
PHP Code:
$name=addslahes($row['name']);
echo('<tr><td><a href="javascript:
void(parent.frameB.location=/'frameB.php?name='.$name.'&desc='.$desc.'/');
void(parent.frameC.location=/'frameC.php?name='.$name.'&number='.$number.'/');"> '.$row['name'].'</a></td></tr>');
(Note that I have put / in above where there is really a just so that it shows up in the post). The link works fine with normal characters in the variable $name, and it works with single quotes in the varable, but not double quotes (the addslashes() escapes single and double quotes with a backslash).
Why doesn't the link work with double quotes in the variable?
I know that using <a href="javascript:"> and <sometag onclick=""> is evil, but in this particular situation it is quite hard to avoid it due to external powers Anyway here is the issue itself : putting javascript strings inside HTML attributes :
Code:
<button onclick="DoSomething('string')">
Everything is fine until there are single or double quotes INSIDE the 'string' value. Having a double quote inside the string, even JS escaped leads to the onclick argument value being cut :
Code:
<button onclick="DoSomething('str"ing')">
If you replace the double quote by '"' then you don't get a double quote inside DoSomething (you could always replace " by " in JS).
Similar problem if you choose to enclose the onclick argument in single quotes and happen to have a single quote JS escaped inside the string.So, is there any other way of dealing with potential presence of single AND double quotes in the 'string' value, other than replacing them before by ' and " and then replacing them back inside DoSomething ?
I have the following form, that allows the user to add text to a form field When they click on an image, this works fine, but I need to slightly change the text that is added to the form. Code:

I have a page that submits to a db then re-loads its self with new information. Unfortunately it goes wrong when the user double clicks on a one of many text links that provides the info for the display on reload. How do I stop users from double clicking on the page? Ideally I think I would like to call some sort of js function from body onload as I presume this would then cover the whole of the page, but have no idea if this is possible or how to go about writing it.
View 8 Replies View RelatedI am passing data from a textarea to a div with javascript. The problem is the div is ignoring line breaks.
document.getElementById('layer1').innerHTML = document.getElementById('reply').value.replace("
", "<br /><br />");
e.g... i entered this in the textarea
test1
test5
test6
the result was in the div
test1
test5 test6
the div is completely ignoring the line breaks.?
I have been writing a script and need a gallery image to have it's width set on page load. My script works fine in safari, ff, chrome..but IE seems to ignore the line that sets the width of the image. It doesn't seem to be ignoring the other widths that are being set on certain divs. So it seems it is an image-only problem.
I thought it best to post a link to the page. To see the problem, you will have to have your browser set smaller than 885px in height. It's line 90 that seems to be ignored by IE
I have a system that provides titles that have had certain characters stripped out. Iwant to be able to select elements in an HTML document that match the titles, even when the titles in the HTML have notbeen stripped.For example, the title "F.B.I" will have the periods stripped to become "FBI", and I want to use that tomatch <div title="F.B.I">.
So far the only way I've been able to do it is to create a new attribute, set it to a stripped version of the title (using e.g. .replace(/./g, '') and match against that. It works, but it seems rather inefficient.Is there a simple and direct way to do this with jQuery?
I'm using the following chunk of code to find images located in a specific span and then I'm setting the span width to equal the width of the image that's inside of it. This is for adding captions to images through an editor that our writers use. By forcing the span to equal the same width of the image, the writers can just enter whatever captions they want and don't have to worry about manually adding <br /> tags to format the captions correctly.
$('.overview-content .caption img')
// once the image has loaded, execute this code
.load(function() {
// Loop through and find all images in the overview section
[Code].....
For some reason... IE and Opera completely ignore this function. Firefox, Safari and Chrome all add the appropriate inline style to the span.
I have to save the state of a form in a var before submitting it with the whole html, but if I alert the var, I get the original html without the updated input fields.

jQuery is ignoring the root element when passed through context. Am not sure if this is intended behavior.[URL]

I'm having some problem trying to escape single quotes. basically, I got some text on the database. if text contains double or single quotes, these are replaced with " and ' respectively. I'm using PHP to alert a portion of the text, let's say "hello, y'all!", this way:
PHP Code:
<?php
echo '<script type="text/javascript">'
echo "alert('hello, y'all!');";
echo '</script>'
?>
well, the js code breaks, just as if ''' were converted to the 'single quote' character. how so?
document.write("<img src=' "+r_image[rand_int]+" '>");
could it not be just written like this:
document.write("<img src='r_image[rand_int]' />");

I use around 50 quotes in the real thing.
I am just learning the basics and am trying to figure out timing with setTimeout()
<script type="text/javascript">
document.write("<p>" + Date() + "</p>");
setTimeout("document.write('Hello There World');", 2000);
setTimeout("document.write("<p>" + Date() + "</p>");", 2000);
</script>
the 1st document.write works and the 1st setTimeout() works, but then I add the fourth line and the page will not load.
Why does it not like my 4th line : "setTimeout("document.write("<p>" + Date() + "</p>");", 2000);"?
I have major problems with quotes or apostropes copied from either a Word document or a web browser giving me box characters on my Cold Fusion MX 6.1 web pages using Access 2000 database after my Updates or Inserts.
I would like to get rid of the quotes and apostrophes on the client side using javascript.
The problem is how do I get the Microsoft quotes or apostrophe because it seems to be a different character than a regular quote or apostrophe.
Here is my attempt but it doesnt catch the "weird" Word or Browser quotes or apostrophes.
function ReplaceQuotes(val)
{
myFieldValue = val
myFieldValue = myFieldValue.replace(/'/g,"")
myFieldValue = myFieldValue.replace(/"/g,"")
alert(myFieldValue)
}

function view(text)
{
document.getElementById("textbox").innerHTML="<input type='text' value='"+text+"'>";
}
</script>
<a href="#" onclick="view('a ' " ')">click to view textbox</a>
<div id="textbox"></div>
this is an example of what im trying to do in a site. what this code does is when you click on hyperlink it shows a textbox in the div with text but single quote is causing problem and not letting it show the textbox even though i have escaped the single quote it will still not work double quote is working fine.
my guess is since i first send it to function and then function prints it so the escape i did is removed and it starts giving error and will not print textbox in the div. can anyone tell what should i add to escape and make it working i tested it in textarea its working there only it causes problem in textbox.
