JavaScript - Escape() In Javascript
What is the need of using escape() in javascript ?
I am unable to understand this escape(). What happens if escape() is not used ? Can someone , please explain in detail ? Thanks Similar Tutorialsall OK, appears as expeced Code: tmpHTML += "<input style = '" + "color:red;" + "' ... all I get is string "color:red" from whole line of code, no errors in javascript console Code: tmpHTML += "<input style = '" + (arr1[i].split("|")[1] != null)?"color:red;":"color:blue;"; + "'....
? Hi, i am new to Javascript i want to know what is the use of the escape() function i read it on w3schools that the function is to encode the string passed top it so as it convert into ascii format so that it can be transferred over any network, can anybody explain me this with an example. Please recommend Regards ltoso In my coding I have the following lines: Code: for (index = 0; index < slidesNumber; index++)
{
$('<a href="#"></a>')
}
Now I want to give each href a unique name with the index variable. So it should look like Code: $('<a href="#index"></a>')
Problem is that it just displays the word 'index', and I don't know how to escape it, so that it displays the value of index. Who can help me out? Hi there, I have been told I need to use escape() and unescape() to fix some issues I am having with my Javascript in IE7. I've been fiddling with it for two days now and can't seem to get it working correctly. It would be amazing if someone on here could spare a few minutes to tell me what my code should look like. It already works fine as is in new browsers, but IE7 is the problem! Here's my Javascript (I've removed my efforts at escaping and unescaping, and also blanked my Facebook app ID out with 123456789): Code: <script>
FB.init({
appId:'123456789', cookie:true,
status:true, xfbml:true
});
function shareProduct(captionvar, descriptionvar, picturevar) {
FB.ui({ method: 'feed',
link: 'http://www.facebook.com/rjthompsonmusic?sk=app_123456789',
name: 'RJ Thompson Official Facebook Store',
caption: captionvar,
description: descriptionvar,
pictu picturevar
});
}
</script>
And here is how it is being called: Code: <a href="#" onclick="shareProduct('Illogical Life - Digital Download', 'RJ Thompsons 2006 album "Illogical Life" available for Digital Download from his Facebook Store. Includes the single "Green Eyed", live favourites "Jester" and "Piano Song", and 8 more original tracks. Only £7.49!', 'http://www.rjthompsonmusic.com/facebook/illogical_life_270.jpg')">

Would really appreciate any help with this. Many thanks, Chris Happy new Year, I need to use the escape() function to protect a string before sending it with a POST request. Alas , the function escape() is not supported on the Javascript engine used ( WITBE scenario doesn't support DOM specific functions ). Has anybody the code, in JAVAscript of this function ? Cos without it the POST request doesn't work as expected. Cheers, Didier. Code: <html>
<body>
<div id="link">
<a href="http://www.facebook.com/">Facebook</a>
</div>
<script type="text/javascript">
var addr=new Array();
addr[0]="http://www.google.com/";
addr[1]="http"//www.yahoo.com/";
addr[2]="http://www.bing.com/";
var rl=document.getElementById("link");
var ri=Math.floor(Math.random()*3);
rl.innerHTML=
</script>
</body>
</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. I have a form with an action url, but I need to alter it on submit. What I need to do is take the value of the text field, escape it, and append it on the end of the action url. Something like this: action url: /search/node appended action url: /search/node/some_escaped_string To do this, I create the function ahead of time and change the submit to a button with onClick. What isn't working is the escape mechanism. If I were to test for "ttt hhh", I'll get "/search/node/ttt hhh", instead of "/search/node/ttt%20hhh" Code: <script type="text/javascript">
function urlAppend()
{
termsValue = document.getElementById('terms').value;
escapedVar = escape(termsValue);
appendedUrl = "/search/node/" + escapedVar;
location.href = appendedUrl;
}
</script>
<form method="get" action="/search/node">
<input type="text" name="terms" id="terms"></input>
<input type="button" value="Search" onClick="urlAppend();">
</form>
Can someone tell me what I'm doing wrong? I want to have another go at Javascript. I have several books on the subject but I find that my eyesight is a major problem. Therefore I want to try an on-line solution, preferably free. I have Googled, but there are so many that I am almost dizzy with the choices. Perhaps someone could recommend one. Not too fussy visually. My knowledge is VERY basic. Frank Hello! I am trying to find a script that allows you to open multiple browser tabs and then close each of those tabs, either one by one or all at once. Does anyone know how to do this please? Thanks so much for your help. Does anyone know how to make URL links that use Javascript still work when users have Javascript disabled on their browser? The only reason I'm using JS on a URL is because my link opens a PDF file, and I'm forcing it not to cache so users have the latest version. I tried the <script><noscript> tags, but I'm not sure if I'm using it correctly, as my URL completely disappears. Below is my HTML/Javascript code: <p class="download"> <script type="text/javascript">document.write("<span style=\"text-decoration: underline;\"><a href=\"javascript:void(0);\" onclick=\"window.open( 'http://www.webchild.com.au/mediakit/Direct_Media_Kit_Web.pdf?nocache='+ Math.floor( Math.random()*11 ) );\" >The Child Magazines Media Kit</a></span> (PDF 1 MB) ");</script> <noscript><span style="text-decoration: underline;"><a href="http://www.webchild.com.au/mediakit/Direct_Media_Kit_Web.pdf" >The Child Magazines Media Kit</a></span> (PDF 1 MB)</noscript> </p> Thanks for any help, Michael Hi, I have the following code snippet: test.html ====== <script language="javascript" type="text/javascript"> var testVariable = "test"; </script> <script language="javascript" type="text/javascript" src="test.js"> </script> test.js ===== var testVariable = window.top.testVariable; In firefox, I'm able to access testvariable defined within test.html in test.js. But in chrome, test.js couldnot get the window.top.testVariable field defined in test.html. Can any one please let me know how i can make it work in chrome?. Am i missing something here?. Hi Guys, I am new at JavaScript and start to do some tutorials.What I am trying to do here is prompting user to input a name and if the name was valid the page(document) will display with all objects like the button.But if user enter a wrong name then the button will be disabled! I create the following code but it did not work <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>New Web Project</title> <script language="JavaScript" type=""> function changeColor(){ document.bgColor = "Gray"; } </script> </head> <body> <script language="JavaScript" type="text/javascript"> var person = ""; person = prompt('What is Your Name:'); if (person == "Foo") { document.write("<h1 />Welcome " + person); document.bgColor = "Yellow"; } else { document.write("<h1 />Access Denied!!!!"); document.bgColor = "Red"; document.getElementById("gree").disabled = true; } </script> <div> <p/><input id="gree" type="button" value="Gray " onClick="changeColor();"> </div> </body> </html> as you can see I used the: document.getElementById("gree").disabled = true; but it did not work , could you please give an idea how I can solve this problem? Thanks I got an index.php Code:
<html>
<form action="bacakomik.php" method='post'>
<select name="kodekomik">
<option value='../komik1/|23'>Judul Komik1</option>
<option value="../komik2/|20">Judul Komik2</option>
<option value="../komik3/|10">Juduk Komik3</option>
<option value="../komik4/|20">Judul Komik4</option>
</select>
<input type="submit" />
</form>
<?php
echo ('<select>');
echo ('<option value= "'.$i.'">'.'Page '.$i.'</option>');
echo ('</select>');
?>
</html>
As you can see, each of the option brings specific value "../komik1/|23" komik1 is a directory | is a delimiter 23 is the pages in one chapter and can be considered also as how many images are there on a specific directory This is my bacakomik.php Code: <?php
$dirkomik = $_POST['kodekomik'];
$exploded = explode("|", $dirkomik);
echo ($exploded[0]); //picture directory
echo ("<br>");
echo ($exploded[1]); //total page in the comic
$pagecount = (int)$exploded[1];
//Take last posted value, process it right away
echo ('<FORM name="guideform"> ');
echo ('<select name="guidelinks">');
$i=1;
do {
echo ('<option value= "'.$i.'">'.'Page '.$i.'</option>');
$i= $i+1;
}while($i <= $pagecount); //Printing option and select
echo ("</select>");
?>
<input type="button" name="go" value="Go!" onClick="document.getElementById('im').src=document.guideform.guidelinks.options[document.guideform.guidelinks.selectedIndex].value+'.png';"> </FORM>
<img src="img0.jpg" id="im">
With the current code on bacakomik.php, I only can change the img src of id "im" in the same directory only. What I want is that the Javascript could "add" the "$exploded[0]" variable so that the picture can be loaded from different directory. Anyone can do this? I believe that the fix should be somewhere on input tag inside OnClick, or do you know where? Anyway, I found this on the net http://p2p.wrox.com/php-faqs/11606-q...avascript.html Please help me to those who can... Hey, I've got to make the values of some textboxes change the co-ordinates of my sprite on a canvas and havent a clue on how to do it, Here is my form with the two textboxes and submit button: <form> x: <input type="text" name="x" /><br /> y: <input type="text" name:"y" /><br /> <input type="submit" value="Submit"/><br /> </form> And i need it so that they change the values of these: //this shows where my sprite will start on the canvas var block_x; var block_y; searched the internet for hours and cant really find anything i understand or works. any help is much appreciated I want to insert this js snippet Code: function addText(smiley) {

.... Code: parent.chtifrm.document.getElementById('chatbox_option_disco').style.display == 'none'
but how do I insert js in the head of loaded iframe? Hi Guys I am trying to modify the functionality of my page. I want to be able to activate this piece of code using another javascript function. This is the code I want to activate: Code: <script type="text/javascript"><!--
$('#button-cart').bind('click', function() {
$.ajax({
url: 'index.php?route=checkout/cart/update',
type: 'post',
data: $('.product-info input[type=\'text\'], .product-info input[type=\'hidden\'], .product-info input[type=\'radio\']:checked, .product-info input[type=\'checkbox\']:checked, .product-info select, .product-info textarea, .date_data input[type=\'text\']'),
dataType: 'json',
success: function(json) {
$('.success, .warning, .attention, information, .error').remove();
if (json['error']) {
if (json['error']['warning']) {
$('#notification').html('<div class="warning" style="display: none;">' + json['error']['warning'] + '<img src="catalog/view/theme/default/image/close.png" alt="" class="close" /></div>');
$('.warning').fadeIn('slow');
}
for (i in json['error']) {
$('#option-' + i).after('<span class="error">' + json['error'][i] + '</span>');
}
}

$('#notification').html('<div class="success" style="display: none;">' + json['success'] + '<img src="catalog/view/theme/default/image/close.png" alt="" class="close" /></div>');
$('.success').fadeIn('slow');
$('#cart_total').html(json['total']);
$('html, body').animate({ scrollTop: 0 }, 'slow');
}
}
});
});
//--></script>
And this is how I want the format of the function to be: function testsession() { if there is a session called 'hiredate' { activate the script above } else { var el = document.getElementById("product_data"); } } I just dont know how to write this in javascript Could you help me if possible please All -- I have a JavaScript config file called gameSetting.js which contains a bunch of variables which configures a particular game. I also have a shared JavaScript library which uses the variables in gameSetting.js, which I include like so: <script type="text/javascript" src="gameSetting.js" ></script> <script type="text/javascript" src="gameLibrary.js" ></script> In gameSetting.js I have: $(document).ready(function() { // call some functions / classes in gameLibrary.js } in Firefox, Safari, and Chrome, this works fine. However, in IE, when it's parsing gameSetting.js, it complains that the functions that live in gameLibrary.js aren't defined. When it gets to parsing gameLibrary.js, the variables in gameSetting.js are reported as not being defined. I've tried dynamically bootstrapping the gameLibrary file using this function in document.ready for dynamic load... $.getScript("gameLibrary.js"); However, the same problem still happens in IE, where when it parses the files individually it's not taking into context the file/variables that came before, so it's not an out of load order problem. My options a 1) collapsing all the functions in gameLibrary.js and variables in gameSetting.js into one file. However, this is not practical because this is dealing with literally hundreds of games, and having a gameLibrary.js in ONE location for ONE update is what makes most logical sense. 2) figure out a way to get this to work where variables in file1 are accessible to file2 in IE (as it seems they are in other browsers). jQuery seems to be able to have multiple plugins that all refer to the based jQuery-1.3.2.js, so I know there is a way to get this to work. Help appreciated. Nero I wrote a log function that took note of various function calls. Thinking that functions are first class objects, and objects have properties, I made the name of each logged function a property of that function, e.g., brightenInnerPara.name = "brightenInnerPara"; Every browser I tried (Firefox, MSIE, Opera, Chrome, Safari) accepted the assignment, no problem. In Firefox and MSIE, the result was what I wanted: brightenInnerPara.name == "brightenInnerPara" But in the others, the result was: brightenInnerPara.name == null Question 1. Which Javascript is correct here? I favor Firefox and MSIE, not merely because they were willing to give me what I wanted, but also because it makes no sense to accept an assignment statement without throwing an error and then give it a null semantics, like Chrome, Opera, and Safari did. I found a workaround, using assignments like this: brightenInnerPara.prototype.name = "brightenInnerPara"; To my surprise, that worked in every browser. But I don't know why. It seems that such assignments are enough to cause each function to have its own distinct prototype. Question 2. Just how inefficient is my workaround, and why does it work? I got the function mouseon to work when I commented out everting and just put the alert in there but when I commented out the alert the rest wont run??? What did I do wrong?

The function should also change the font color and background color. Return it to its original state when the mouse leaves the heading. </p> <p>2.

Change the font face, color, size and background to corresponding to the time of day. </p> <p>5. Create a function that will ask the user for one of the following colors: blue, green, yellow, orange. If the user enters an invalid color display a message and change the color of all the following paragraphs to red. Otherwise change the color of the indicated paragraph using the same generic function for each paragraph. Example: User enters green then change the green paragraph to green text, etc.</p> <p>This is blue!</p> <p>This is green!</p> <p>This is yellow!</p> <p>This is orange!</p> <p><strong>Extra credit:</strong> In 5. Instead of changing the whole paragraph only change the color name.
