Typing In Javascript?	View Content

I know there's a way to do it in Jquery, but in simple javascript is there a way to "type" into a textbox? Or, modify what's typed? I tried using macros but it doesn't fill out the form after refresh.

How To Make Url Link That Uses Javascript Work If Javascript Is Disabled?

Similar Tutorials

View Content

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

Javascript Problem, Editing Img Src With Javascript

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

Javascript Config File + Javascript Class/functions File - Variables Not Found

Similar Tutorials

View Content

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.

Are Functions "first Class Objects?" And Javascript != Javascript

Similar Tutorials

View Content

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?

Trying To Pur Php Is Javascript And I'm New To Javascript

I downloaded a javascript file that works GREAT. It shows and hides div's in the code on demand. My problem is that in my code the divs in question are forms that are submitted. The handler for the forms is the same page. So the first time I visit the page all the sections are hidden. I expand a div, add some information and submit. Then the page refreshes and all divs are hidden again. I have to reexpand the div again to continue my work. Not a HUGE deal except when I have a ton of data entry to do.

So I have a plan. I have created a table in the data base to hold a 1/0 value. I want the javascript that shows the sections to simply check the table. IE if the page is loaded, check the database to see which sections should be hidden and which should be visible.

I THINK the place to add it is the fuction called "showhide" on line 53 but I'm not sure if that's correct nor do I have any idea how to make it accept the value from the database.

Whew! I hope I made that clear. Below is the code for the javascript and the code of the webpage in question. Can anyone help?

Code:

//** Animated Collapsible DIV v2.0- (c) Dynamic Drive DHTML code library: http://www.dynamicdrive.com.
//** May 24th, 08'- Script rewritten and updated to 2.0.
//** June 4th, 08'- Version 2.01: Bug fix to work with jquery 1.2.6 (which changed the way attr() behaves).
//** March 5th, 09'- Version 2.2, which adds the following:
			//1) ontoggle($, divobj, state) event that fires each time a DIV is expanded/collapsed, including when the page 1st loads
			//2) Ability to expand a DIV via a URL parameter string, ie: index.htm?expanddiv=jason or index.htm?expanddiv=jason,kelly

//** March 9th, 09'- Version 2.2.1: Optimized ontoggle event handler slightly.
//** July 3rd, 09'- Version 2.4, which adds the following:
			//1) You can now insert rel="expand[divid] | collapse[divid] | toggle[divid]" inside arbitrary links to act as DIV togglers
			//2) For image toggler links, you can insert the attributes "data-openimage" and "data-closedimage" to update its image based on the DIV state
