JavaScript - Javascript Replacement
I am now able to list the folders and files in a directory.
However, when I try to pass the values into another function to open the folder/file, I encounter an error saying object expected. I'm guessing that its the \ in the file paths that is causing the error. so my solution is to find the \ and replace it with a \\ before passing it to the function to open the file. but the str.replace("\\","\\\\") does not seem to work. any ideas? thanks! Similar TutorialsHi all, As the title suggests, I'm new to JS and I've been working with HTML, CSS, and PHP for the past few years. I've decided to add some interactivity to my websites and one of the new courses requires JS in our implementations, so I figure why not. Anyhow, more to the point...the topic is a bit vague, but I didn't want to put a 50 word topic either so bear with me as I try to explain : Okay, so I'm designing an art portfolio page and I have a 250x250 pixels preview shot of an art piece on my side bar at the top. There is a horizontal column at the bottom of the page (before the footer) that contains about 6 to 8 mini thumbnails around 100x100 pixels. Right now, I am able to make it so that if I mouse over the bottom thumbnails, the 250x250 at the sidebar is replaced to reflect what was hovered at the bottom, only in a bigger size. This is my current coding: Code: <script type="text/javascript">
<!--
function change_img(path) { document.large_img.src=path}
function preload(){
myImg01 = new Image();
myImg01.src = "/msjb/wp-content/themes/msjb_theme/images/front_gal/arrival.png";
differentImag = new Image();
differentImag.src = "/msjb/wp-content/themes/msjb_theme/images/mini_gal/arrival.png";
}
-->
</script>
From that point, I would insert the following code with each 100x100 thumbnail: Code: onmouseover="javascript:change_img('/msjb/wp-content/themes/msjb_theme/images/front_gal/wind.png')"
I'm not even sure if that's the correct or most efficient way to do it...it took me a while to figure out, and it finally worked so I went along with it. What I want to do, and what I need help with is...I'd like to give the current artwork, or the piece that's currently @ 250x250 pixels at the sidebar a title. Preferably, perhaps from the context of the alt tag from an img src but not required. However, I would like for it to change to the corresponding pieces' title when I mouseover, so for example: 250x250 piece1's name is ...art1 and that name is located right under the image. I mouse over the bottom thumbnails to the 5th thumbnail, the 250x250 piece1 is replaced and becomes 250x250 piece5. I'm trying to make it so that art1 becomes art5. I'm really bad at explanations so it was clear enough for some sort of understanding. I do appreciate the help, and thanks for time! I am very much a newbie at Javascript, so your help is greatly appreciated. I am working on trying to create a Picture Bingo JavaScript.

Thanks for your help! Joe What other methods can I use to insert code into my HTML pages from an external file, that will be able to be picked up by search engines and will show entirely if you do a "View Source" on my page? I've been using document.write functions in my personal home page for doing things like maintaining nav. bars, footers, etc. However, the HTML that's written using document.write is not picked up by search engines being that its browser-side instead of server-side and if you view the source of the page, all it shows is the call to my JS function that does the document.writes. Hi, im using this code as a fancybox replacement for confirm. Code: function fancyAlert(msg) {
jQuery.fancybox({
'modal' : true,
'content' : "<div style=\"margin:1px;width:240px;\">"+msg+"<div style=\"text-align:right;margin-top:10px;\"><input style=\"margin:3px;padding:0px;\" type=\"button\" onclick=\"jQuery.fancybox.close();\" value=\"Ok\"></div></div>"
});
}
function fancyConfirm(msg,callback) {
var ret;
jQuery.fancybox({
modal : true,
content : "<div style=\"margin:1px;width:240px;\">"+msg+"<div style=\"text-align:right;margin-top:10px;\"><input id=\"fancyConfirm_cancel\" style=\"margin:3px;padding:0px;\" type=\"button\" value=\"Cancel\"><input id=\"fancyConfirm_ok\" style=\"margin:3px;padding:0px;\" type=\"button\" value=\"Ok\"></div></div>",
onComplete : function() {
jQuery("#fancyConfirm_cancel").click(function() {
ret = false;
jQuery.fancybox.close();
})
jQuery("#fancyConfirm_ok").click(function() {
ret = true;
jQuery.fancybox.close();
})
},
onClosed : function() {
callback.call(this,ret);
}
});
}
function fancyConfirm_text() {
fancyConfirm("Ceci est un test", function(ret) {
alert(ret)
})
}
how can i use fancyConfirm via an onclick in a hyperlink? thanks for your help! OK so I have a variable called url and I want to move its contents into the form action once the button is submitted. <script type="text/javascript"> function elibrarySearchGo(){ var url = "http://url'" } </script> <form name="searchform" target="_blank" action="" onsubmit=""> I need the syntax as to how to put in a variable coming from javascript inside onsubmit="document.form.action.value = variable" for example. Also, is it better to run this population of the action onsubmit or onclick? Thanks all in advance!! 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 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... 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? 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 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>');
}
}
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 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? Hi all I am having x.php file in that i have included (y.js file). x.php code <? $username = "Kelvin"; ?> y.js code (external file) var username =<?php echo'$username';?> alert(username) It is not working for me. How can i get the php variable in external js file. Any help! I have these lines of codes, but I can not get the calendar shown in the browser. can anyone help me on this. Thanks! <html> <head> $(document).ready(function() { $('#calendar').datepicker({ dateFormat: 'yy-mm-dd', changeYear: false, changeMonth: false, minDate: '-1m', maxDate: '+2m', }); </head> <body> <div id='calendar'> </div> </body> </html> First of all, I would like to say a few things. I have no idea how to program anything. I am looking for some help. I typed in 'javascript help forums' in google and this was the first thing on the list. I am looking to combine the effects of these two javascript. Code: javascript:__doPostBack('ctl00$ctl00$cphRoblox$cphMyRobloxContent$AttireListView$ctrl0$ctl02$WearAccoutrementButton','')
Code: javascript:__doPostBack('ctl00$ctl00$cphRoblox$cphMyRobloxContent$AttireListView$ctrl0$ctl01$WearAccoutrementButton','')
I don't know if you need to know anything else where you can combine these two, but I can get it probably if you do. Thanks I am quite new to using javascript and am currently trying to create a real-time username checker. Once the user enters the username I would like some javascript to run and check whether the username is already in the database, then if it is return 'this is already in use'. Unfortunately I am not able to use ajax. I would be very grateful for any help with this matter, and any example code would be much appreciated. Phil |
