Problem With Double Quotes In Javascript Link
Feb 10, 2003
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'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 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 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.

I am creating a training manual but i find using pictures slightly
boring. I have created Shockwave/flash files showing in detail how to
use certain things.
I have tried to embbed the shockwave file into powerpoint and it kind
of works.
What i want is to create a link which opens the shockwave file in a new
window, but just the shockwave file without any toolbars or anything.
I noticed javascript files open in a new window which is ideal for me.
How do i do that? I have a powerpoint file and a shockwave file??

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?

I'm writing a FireFox extension and I have the dom and therefor the
links[] collection
window.getBrowser().contentDocument.links[i]
Is there a way to change the color of these links based on the stuff I'm
checking for from the JavaScript?
For example. If I have this loop
var number_of_links = window.getBrowser().contentDocument.links.length;
for (var i=0; i < number_of_links; i++)
{
var domain = window.getBrowser().contentDocument.links[i].hostname;
//Check hostname here and change color
}
how could I change the links color?

I have a form that I would like to get the values entered on the page
and go to a new page in the same window. I can make the code work to
open a new window, but I need it to open in the same window. Here is what I have:
function pass_info() {
var info = "";
info += document.form2.productWeight.value;
window.open("/page/shippingrates/calculate_shipping_before.asp"
+ "?" + "weight=" + info,");
}
I know that it is the window.open, but I have not figured out what I
need to do to get it in the same window.

How do I create an email link using javascript attached to an image link?
The simpler methods I have so far been able to find only work within form elements.
I have also tried...
window.location="mailto:contact@mydomain.com"
parent.location="mailto:contact@mydomain.com"
location.href="mailto:contact@mydomain.com"
... none of which seem to work.
What's the secret? Where am I going wrong?

This little snippet of code produces random quotes but sometimes gives a missing quote between two quote marks.

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);"?
