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?
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 ?
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
(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:
When publishing bookmarklets, we put the bookmarklet code in anchor tag like this:
<a href="javascript: alert('test');"name </a>
Some characters of the code need to be escaped. For example, double quotes need to be escaped as %22 like in this example: <a href="javascript: var doubleQuote = '%22' alert(doubleQuote);"> name </a>
Question: Is double quotes the only thing that need to be escaped?
I have seen examples of escaping spaces as %20, but it seems unnecessary in most browsers i have used.
The problem with the loop is that it's infinite, which I understand is generally not a very clever solution. In this particular case I would like to escape the loop with P20 and then link to a new page.
Is there any method for <input> tag like .html() to escapsing html code? Example with a label, I can use: $("#label").html("NGUYỄN") will become NGUYỄN (that what I want); so I want to do the same thing with <input> tag.
Clicking this link works great. The data is loaded into the content div as expected. But the problem is the html that is loaded into the div has funny-looking characters where the single and double quotes should be. (See attachment).
What do I need to do in order to make the quotes show up properly?
I'm dynamically generating an image tag, and the final slash for self-closing the tag is not coming through, even though the slash is escaped with a backslash. Worse, I think this is screwing up my attempt to select the image in another function. Any ideas what could be causing problems? [code]The image does appear, but I can't reference it later on.While everything works fine if I drop the " img" from the call and let clicking anywhere in the div start the search.Any idea why escaping the slash isn't working?
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.
Code: <script language="JavaScript"> var checkobj function agreesubmit(el){[code]....
i need to make it like if the button is clicked and there the agreement checkbox is not checked.. it should give an alert that the alert is not checked.. i know that would require a if and else statement but i cant figure out how to do it

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:
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) }
