JavaScript - Javascript Documentation
Where can I get javascript documentation for offline usage?
Similar TutorialsHey All, Recently, I finished making the first version of my own JavaScript framework. Basically, I like Prototype and jQuery so I made one that has what I personally like the best about both of them. Regardless, I'm hoping someone can guide me in the right direction to finding a nice JavaScript documentation creator. Or something that can at least parse my code and get me a decent start on creating the docs. I would also love to easily stylize the pages too. Thanks everyone! Rick I have been searching for years to get ahold of a complete reference to the ECMAscript languages. I was recently watching some old videos by Douglas Crockford. He talked about the 'set' and 'get' statements. I had never heard of them before... and infact was one of the things I really missed from Delphi and have been wishing for in javascript. Even now I can't find any references that contain them. I keep having this feeling that there is so much more in the language than I know about and there is no easy way to learn it. Where is the most complete reference of the language? David 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. 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 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 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 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?. 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... 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',

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>');
}
}
if (json['success']) {
$('#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 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) {
document.getElementById('message').value += " " + smiley + " ";
document.getElementById('message').focus();
return false;
}
to a loaded iframe with name&id chtifrm. I can access it & change embed something in its html via using something like: Code: $(parent.chtifrm.document.body).append('<div id=\"smly\" style=\"cursor:pointer;float:left;top:200px;display:none;position:absolute;\"><\/div>');
.... Code: parent.chtifrm.document.getElementById('chatbox_option_disco').style.display == 'none'
but how do I insert js in the head of loaded iframe? 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? Hey guys I know this might have been discussed before but i can't find it anywhere. I'm trying to write javascript with javascript.... simple right well the problem is in my script i have javascript writing the </script> line like this Code: <script type="text/javascript">
if (!Array.prototype.forEach)
{
Array.prototype.forEach = function(fun, thisp)
{
var len = this.length;
if (typeof fun != "function")
throw new TypeError();
var thisp = arguments[1];
for (var i = 0; i < len; i++)
{
if (i in this)
fun.call(thisp, this[i], i, this);
}
};
}
var typeArray = function (x) {
document.writeln('<script type="text/javascript">observe(x); </script> ');
}
var myArray = [1,2,3,4,5];
myArray.forEach(typeArray);
</script>
When this code is ran it ends at the first </script> tag and you see all the code after it as just text. i need this code to work because the function observe(); is an observer and has to be in the code for each instance of x. but when the </script> tag is written, even inside the "" it ends the code. Is there any way to write the </script> tag inside of javascript without ending the code?? sorry about my english... i have logo slider in javascript this is the code: var displayWaitMessage=true; // Display a please wait message while images are loading? var activeImage = false; var imageGalleryLeftPos = false; var imageGalleryWidth = false; var imageGalleryObj = false; var maxGalleryXPos = false; var slideSpeed = -1; var imageGalleryCaptions = new Array(); function startSlide(e) { if(document.all)e = event; var id = this.id; if(this.id=='arrow_right'){ slideSpeedMultiply = Math.floor((e.clientX - this.offsetLeft) / 5); slideSpeed = -1*slideSpeedMultiply; slideSpeed = Math.max(-10,slideSpeed); }else{ slideSpeedMultiply = 10 - Math.floor((e.clientX - this.offsetLeft) / 5); slideSpeed = 1*slideSpeedMultiply; slideSpeed = Math.min(10,slideSpeed); if(slideSpeed<0)slideSpeed=10; } } function releaseSlide() { var id = this.id; slideSpeed=-1; } function gallerySlide() { if(slideSpeed!=0){ var leftPos = imageGalleryObj.offsetLeft; leftPos = leftPos/1 + slideSpeed; if(leftPos>maxGalleryXPos){ leftPos = maxGalleryXPos; slideSpeed = 0; } if(leftPos<minGalleryXPos){ leftPos = minGalleryXPos; slideSpeed=0; } imageGalleryObj.style.left = leftPos + 'px'; } setTimeout('gallerySlide()',50); } function showImage() { if(activeImage){ activeImage.style.filter = 'alpha(opacity=50)'; activeImage.style.opacity = 0.5; } this.style.filter = 'alpha(opacity=100)'; this.style.opacity = 1; activeImage = this; } function initSlideShow() { document.getElementById('arrow_left').onmousemove = startSlide; document.getElementById('arrow_left').onmouseout = releaseSlide; document.getElementById('arrow_right').onmousemove = startSlide; document.getElementById('arrow_right').onmouseout = releaseSlide; imageGalleryObj = document.getElementById('theImages'); imageGalleryLeftPos = imageGalleryObj.offsetLeft; imageGalleryWidth = document.getElementById('galleryContainer').offsetWidth - 80; maxGalleryXPos = imageGalleryObj.offsetLeft; minGalleryXPos = imageGalleryWidth - document.getElementById('slideEnd').offsetLeft; var slideshowImages = imageGalleryObj.getElementsByTagName('IMG'); for(var no=0;no<slideshowImages.length;no++){ slideshowImages[no].onmouseover = showImage; } var divs = imageGalleryObj.getElementsByTagName('DIV'); for(var no=0;no<divs.length;no++){ if(divs[no].className=='imageCaption')imageGalleryCaptions[imageGalleryCaptions.length] = divs[no].innerHTML; } gallerySlide(); } function showPreview(imagePath,imageIndex){ var subImages = document.getElementById('previewPane').getElementsByTagName('IMG'); if(subImages.length==0){ var img = document.createElement('IMG'); document.getElementById('previewPane').appendChild(img); }else img = subImages[0]; if(displayWaitMessage){ document.getElementById('waitMessage').style.display='inline'; } document.getElementById('largeImageCaption').style.display='none'; img.onload = function() { hideWaitMessageAndShowCaption(imageIndex-1); }; img.src = imagePath; } function hideWaitMessageAndShowCaption(imageIndex) { document.getElementById('waitMessage').style.display='none'; document.getElementById('largeImageCaption').innerHTML = imageGalleryCaptions[imageIndex]; document.getElementById('largeImageCaption').style.display='block'; } window.onload = initSlideShow; now when it's get to the last logo the slider is stop, and you can move with the arrow right and left and want to change that the slider don't stop and keep move in looping. i really need help! thank you very much. Can I dynamically change a text color when it goes through this attached image or div,(it does not matter)? I know how to change a color; however, I don’t know what conditions I need here. Is there a way to do it? here is the link: My idea is : to make text red when it is on the top of blue div but I have no idea how to achieve it. Once text is out of the blue div region, I want it be black again. I'v very new to javascript and need some help. Here's what I need to do: I need to have a text input with a button, and when the button is clicked the text must be copied to a div. When copying, each character needs to be placed on a separate line within that div container. Before this happens though, the content currently in the div must be cleared. This probably very simple, but as I said i'm new and confused out the wazoo. Thanks in advance!
