JavaScript - Getting Double Quotes Into Coding
Hi, 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 Cheers George Similar TutorialsHi Can you please advise on this. When writing javascript what is best practice.... single or double quotes? I tried to research this and everyone contracdicts each other? thanks A I've got this bit of code that I've wrote and it was working absolutely fine like this: Code: function validatepostcode() {
var postcodevalue = document.getElementById("postcode").value;
if (postcodevalue.indexOf("S") == -1)
{
alert(postcodevalue + " is not a valid postcode.");
}
}
Until I tried to add double quotes: Code: function validatepostcode() {
var postcodevalue = document.getElementById("postcode").value;
if (postcodevalue.indexOf("S") == -1)
{
alert( \" postcodevalue \" + " is not a valid postcode.");
}
}
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? Regards, Hashim. action3.innerHTML = '<input type="button" class="menuButtons" id="menuButton1" value="Lab1" onclick="requestWindow("e;../lab1.html"e;)" />... how can I fix that. I tried "es for a third quote after already using single quotes and double quotes but it still hates me =[ This little snippet of code produces random quotes but sometimes gives a missing quote between two quote marks. Code: <HTML>

I got stuck in getting this to work (show random element of the array as a link with description) Code: rl.innerHTML='<a href="addr[ri]">addr[ri]</a>'; This is showing addr[ri] on a page and directs to www.domain.com/addr[ri] Thank you in advance for any info.

Thanks in advance i've made an app in php/mysql which generates random quotes at intervals. i'm trying to integrate it with facebook. if i use iframes, everything works smoothly except for one issue, that facebook doesn't support iframe in profile boxes - which is what i want. for this reason, i prefer to use fbml. however, i'm using jquery to get the quotes from the php file, and this doesn't work in fbml. i read that with fbml, i can work with fbjs. since i do not know fbjs, i'm stuck. how do i convert the jquery code to get the quotes from php to fbjs? specifically, which part from the jquery file do i need to convert to fbjs, to get my code to work using fbjs? any help would be appreciated. i tried using fbjqry, but it didn't work. this is my code: Code: <!DOCTYPE html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">

I am just learning the basics and am trying to figure out timing with setTimeout() Code: <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);"? How can I add single quotes around listObj.options[i].value. I still want to keep the comma I'm adding to the end of it. Code: CSV += listObj.options[i].value + ','; Good morining, I'm working on a javascript for a rollover menu that the client is regularly changing. I want to create a call to a remote "document write" script on each page so that when it changes I only have to modify it in the script rather than on every page of the site. The problem I am having is that I cannot figure out how to include the quotes needed to execute the rollovers without killing the script. I tried removing all the quotes, and the "\" method as I would with a perl script, (and MANY other attempts) but no go. Here is where I'm at right now. I would appreciate any suggestions or links to info I can read to learn from. Call to the script in the html page(s): Code: <SCRIPT language="JavaScript" SRC="Nav_11Set.js"></SCRIPT> The script (condensed to one image): Code: document.write('<table id=Table_01 width=143 height=264 border=0 cellpadding=0 cellspacing=0><tr><td><a href=http://www.minersalley.com/Memberships.html onmouseover=changeImages('Nav_11Set_01', 'images/Nav_11Set_01-over.jpg'); return true;onmouseout=changeImages('Nav_11Set_01', 'images/Nav_11Set_01.jpg'); return true;onmousedown=changeImages('Nav_11Set_01', 'images/Nav_11Set_01-down.jpg'); return true; onmouseup=changeImages('Nav_11Set_01', 'images/Nav_11Set_01-over.jpg'); return true;><img name=Nav_11Set_01 src=images/Nav_11Set_01.jpg width=143 height=24 border=0 alt=Membership Info!></a></td></tr></table>')
Hi , I have a data coming as a string which contains single quotes and double quotes but it is showing up as Code: ' and " it should show it as Code: ' and " How do I fix this issue. in JavaScript. Hey all, have a bit of a problem. I'm trying to store a variable in Javascript that consist of user input that may include both quotes and apostraphes (amongst any other stuff). Currently looks a bit like this: Code: <script>
var importantNote = [[Note]];
if (importantNote != "" && importantNote != " ") {
var importantNoteOutput = "<div class=\"important\"><h3>Important Note:</h3> [[Note]]</div>";
document.write (importantNoteOutput);
}
</script>
Obviously, when [[Note]] (another variable pulled through a seperate program to create complete code) contains ", it doesn't go so well ('[[Note]]' solves that, but creates same issue with any plurals ). I *could* get end user (probably me) to always ensure anything entered in this field (and few others used in a similar way) contain escaped characters, but this isn't preferable. Preferably, I'd like a way of escaping an entire string automatically, eg. encode([[Note]]) - though that doesn't seem to work. Any quick tips? FWIW, I don't think I can use php, or much else for the task. Pretty much stuck with html and javascript. Thanks I'm trying to insert a title and a body into a Google maps window through PHP. The body could contain double or single quotes. How do I output these so that they don't break the script? Relevant code: Code: $('#map_canvas').gmap('openInfoWindow', { 'content': '<strong><?php echo $m->marker->Title; ?></strong><br /><?php echo $m->marker->Body; ?><?php echo '<a href="./marker_info.php?id='.$m->marker->Nid.'"></a>' ?><br /><a id="m_location" href="#" data-role="button" data-icon="search" onclick="$.mobile.silentScroll(500);"></a>'}, this);
the following javascript code is for a page that has to different login sections (username and password) hospital admin i want them to login in their part using normal IDs(numbers) and password, and normal users to login in the other login boxes (using email address and password) , each login boxes have their own submit button. the problem is i can't check each of them alone. what i want to do is that if (for user) email and password entered and pressed his login button, to be headed to another page, while if hospital admin entered his id and password in his section and pressed login button, to be headed for a different page. help please ! Code: window.onload = initForms;
function initForms() {

P.S: I apologize about not using codes, i didn't knew about this option. here is where the code is. http://simplythebest.net/scripts/DHT...script_15.html I need this to be able to open in the parent window not in another window. Or if someone could precribe a double drop box that works in "moonfruit" that would be great. Thank you very much for your time. David hello I have a listbox full of names on a PHP website and was wondering if there was a way to grab the value during a double click to bring me to another form to display the name and information? I currently have a Drop-Down menu, which has headers you click on to show the links. This menu only allows one drop to be expanded at a time, and can be viewed here. I would like the headers to be able to have 'sub-headers' inside, which also drop-down,to reveal the links. I want them to have a different header colour, and to have the same rule where only one can be open at a time. while keeping the rule with the main headers. I have previously posted asking this, and got no reply, so I would really greatly appreciate any help and/support! Best Regards, Tim (P.S. I am still only learning JavaScript, and to make the current menu I have, took loads of help for a different project) Hi guys, I have written a double validation as below function validateDouble(ele){ // Custom trim funcation, i have written if(trim(ele.value) != ''){ var a = /^\d+(\.\d{0,2})?$/.test(trim(ele.value)); if(a){ return true; }else{ return false; } }else { ele.value = '0.00'; return true; } } I have copied from the net But this validation doesnt work when we enter the value as .65 (Means, it should accept this also, Please help me to change the regular expression) and in the same time when we enter this with out prefix, it should auto change to 0.65. Can some one help me to add in the above function. |
