View 1 RepliesI 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.

View 1 Replies View RelatedI am using jQuery and blockUI to prevent the user from submitting a form twice by double clicking on the interface: This is in my global js file and is called on every pages
document.ready:
$('form').submit(function(){$.blockUI({message:'', overlayCSS:
{opacity:0.2}})});
This was working really well, but if I have validation on one of the form submits that returns false, I of course want to unblock the UI.
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
im trying to convert a string into arrays in javascript using split() function.

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 have the task of creating an asp page that generates a standard email newsletter. The HTML Image Width and Height tags need to be set to the actual image size (no they haven't been set to a standard size on the server) as they are read in via an while loop. I believe in ASP, you are out of luck for a function that does this, so Javascript may be the way forward.
My code is as follows for the image inside an anchor tag, as you can see i tried the min and max style properties for the image, but this does not set them exactly. e.g. width="120px" height="94px", which is what is required.
I have a website with an admin area for my clients. The input text is then inserted in a page on their website - inside a <p> tag. What I'm trying to do is locate a script that would allow them to use such tags as <b>, <i>, <u>, but not others like <p>, <div>, etc. Does someone know of such a script?

View 2 Replies View RelatedI'm using this rich text editor. Whenever a user pastes rich text from a program like Microsoft Word, the program's smart quotes are not understood by the browser (they appear as a diamond with a question mark in it). I ran a php function on the post value to replace all quotes with ascii characters, but realized that it also replaces the quotes present in the html generated by the javascript.Is there a way to convert smart quotes to normal quotes without also tampering with the html content?

I have a part of the form to list ingredients which uses 3 for fields, one for quantity one for measurement and one for the ingredient.Quantity is a text field and the other two are selects.
