JavaScript - Indexof() Not Registering With Certain Code Blocks

Hi there!

OK I need a little help as I'm not sure how to integrate this function into my form. First of all I should explain that my form doubles as a Google Search box. If you select the Google Search radio button it submits the input text to Google. It also defaults to Google if anything else other than "red", "green" or "blue" are entered. Now what I'd like to do is add a function so that if someone enters "purple is my favorite color" it recognizes the "purple" part of the string using something like .indexOf('purple'); and calls something like if(function==-1) { theForm.action = "Other choice "+ q.value; . How can I add this to my form? Thank you for any help.

My form code:

Code:

<script>
function convert(theForm){
  var els = theForm.getElementsByTagName('input');// store inputs
  var q = els[0], color = els[1];

  if(els[4].checked){// submit to google
    theForm.action = 'http://www.google.com/search';
    return true;
  };

  color.value = "Chosen "+ q.value +" color";
  switch(q.value){// check the query
    case 'red':
    case 'green':
    case 'blue':
      location.href = color.value;
      return false;
    break;   
    default:
      theForm.action="http://www.google.com/search";
    break;
  };
  return true;
};
</script>

<form name= "myform" onsubmit='return convert(this)'> <input name='q' type='text' /> 
<input name='color' type='hidden' /> <input type='submit' value=" Enter " />
<br />
<input name="searchType" type="radio" value="" checked="checked" > <label for="all"> My Form </label>
<input name="searchType" type="radio" value="google" onclick="document.myform.action='http://www.google.com/search';" /> 
<label for="google"> Google Search </label></form>

i have a div that has a pointer cursor as the style. on click of the div, i'd like to change visibilities of some of my other divs, but i can't get it to run! can someone give me a push here? i think dw is telling me that there is an error in my code, but cant see it... Code:

function getCP() {
if (document.getelementbyid('apdiv11').innerHTML == "VIEW CONTROL PANEL") {
	document.getelementbyid('apdiv11').innerHTML = "BACK TO WEBSITE";
	document.getelementbyid('wb_marquee1').style.visibility = 'hidden';
			document.getelementbyid('apdiv6').style.visibility = 'visible';
					}
else {
	document.getelementbyid('wb_marquee1').style.visibility = 'visible';
			document.getelementbyid('apdiv6').style.visibility = 'hidden';
	 }
}

Hi everyone, this is my first post here and I hope that you can be of assistance!!

I have an issue with a registration form. What I would like to do is only allow a certain email domain in the 'email' field. Eg. Only allowing @gmail.com email addresses, and all others would receive an error.

This is the line of code that I believe needs changing:

function isEmail(valor){if(/^\w+([\.-]?\w+)*@\w+([\.-]?\w+)*(\.\w{2,4})+$/.test(valor)){return(true)}else{return false;}}

I am not too familiar with this but through my hours of research, I believe that I need to add something to this line.

Thanks in advance.

Hi there,

I have been using a javascript to show the news on the front page. It works ok. But I need another one to scroll the product images, again on the frontpage. But when I start to use the second one I see all my news messed up together.

What can be the reason and how can I solve that?

The second (image scroller) javascript is jquery.tools.min.js
and the first one is a Joomla! module.


thanks in advance

This was working. Is there a way around this ?

Hi from Ireland!
I recently signed up to Google Analytics and it began to block my flash content.
I removed the tracker code (javascript) and deleted my account though my flash content is still blocked.

Can someone help? I'll buy you a pint.

regarding this script: http://cssphpmysql.com/dev/my-lifeline/

this is a jsportal 2.0 script written by Michel Hiemstra (http://michelhiemstra.nl); this script fires a few php/mysql UPDATE queries whenever a block is dragged/dropped from column to column, but fails to fire the queries if a block is dragged to a dif. position in the same column - i'm failry noob with jquery/javascript and after a lot of hunting and pecking i'm unable to find why.

here's a bit of the code which i think is pertinent, though not sure. i would be very grateful if someone could offer a little help?

Code:

Portal.prototype = {

	initialize : function (settings, options, data) {

		// set options
		this.setOptions(options);
		
		// set blocks to their positions
		this.apply_settings(settings);
		
		// load data to blocks
		//this.loadData(data);
						
		// if editor is enabled we proceed
		if (!this.options.editorEnabled) return;
		
		// get all available columns
		var columns = $(this.options.portal).getElementsByClassName(this.options.column);
		
		// loop through columns array
		$A(columns).each(function(column) {
			
			// create sortable
			Sortable.create(column, {
				containment : $A(columns),
				constraint  : this.options.constraint,
				ghosting	: this.options.ghosting,
				tag 		: this.options.tag,
				only 		: this.options.block,
				dropOnEmpty : this.options.droponempty,
				handle 		: this.options.handle,
				hoverclass 	: this.options.hoverclass,
				scroll		: this.options.scroll,
				onUpdate 	: function (container) {
					
					// if we dont have a save url we dont update
					if (!this.options.saveurl) return;
					
					// if we are in the same container we do nothing
				    if (container.id == this.options.blocklist) return;
					
					// get blocks in this container
					var blocks = container.getElementsByClassName(this.options.block);
					
					// serialize all blocks in this container
					var postBody = container.id + ':';
					postBody += $A(blocks).pluck('id').join(',');
					postBody = 'value=' + escape(postBody);
					
					// save it to the database
					new Ajax.Request(this.options.saveurl, { method: 'post', postBody: postBody, onComplete : function (t) {
						$('data').update(t.responseText + $('data').innerHTML);
					} });
										
				}.bind(this)
			});
			
		}.bind(this));
	},
	
	apply_settings : function (settings) {
		// apply settings to the array
		for (var container in settings) {
			settings[container].each(function (block) { if (!$(container)) { console.log('Block '+container+' not found') } else { $(container).appendChild($(block)); }  });
		}
	},
	
	setOptions : function (options) {

i've attached the dragdrop.js file as a txt file, also, as it's so large.

I'll be very grateful for any offer of help. thanks loads.

This post will contain a few guidelines for what you can do to get better help from us. Let's start with the obvious ones:

- Use regular language. A spelling mistake or two isn't anything I'd complain about, but 1337-speak, all-lower-case-with-no-punctuation or huge amounts of run-in text in a single paragraph doesn't make it easier for us to help you.

- Be verbose. We can't look in our crystal bowl and see the problem you have, so describe it in as much detail as possible.

- Cut-and-paste the problem code. Don't retype it into the post, do a cut-and-paste of the actual production code. It's hard to debug code if we can't see it, and this way you make sure any spelling errors or such are caught and no new ones are introduced.

- Post code within code tags, like this [code]your code here[/code]. This will display like so: Code:

alert("This is some JavaScript code!")

- Please, post the relevant code. If the code is large and complex, give us a link so we can see it in action, and just post snippets of it on the boards.

- If the code is on an intranet or otherwise is not openly accessible, put it somewhere where we can access it.

- Tell us any error messages from the JavaScript console in Firefox or Opera. (If you haven't tested it in those browsers, please do!)

- If the code has both HTML/XML and JavaScript components, please show us both and not just part of it.

- If the code has frames, iframes, objects, embeds, popups, XMLHttpRequest or similar components, tell us if you are trying it locally or from a server, and if the code is on the same or different servers.

- We don't want to see the server side code in the form of PHP, PERL, ASP, JSP, ColdFusion or any other server side format. Show us the same code you send the browser. That is, show us the generated code, after the server has done it's thing. Generally, this is the code you see on a view-source in the browser, and specifically NOT the .php or .asp (or whatever) source code.

I'm trying to get my Client Side Firefox DHTML app to display a list of eBooks. For this, i have the following files

F:\Textbooks.html
F:\eBooks.txt
F:\FirstBook.txt
F:\SecondBook.txt
F:\ThirdBook.txt


textbooks.html is my DHTML app
eBooks.txt is the Library file with a listing of all of my eBooks.
Inside of eBooks.txt is the following data:
-----------------
FirstBook.txt,
SecondBook.txt,
ThirdBook.txt,
-----------------

FirstBook.txt to ThirdBook.txt are my actual ebooks.


The problem that i'm having is that When i try to click on any buttons other than the FirstBook button, i get the following error:

----------------------------------
Error: unterminated string literal
Source File: file:///F:/Textbooks.html
Line: 1, Column: 10
Source Code:
LoadEbook('
----------------------------------

So, unlike clicking on the FirstBook button, these other buttons do not load the eBook data into the DIV for displaying the eBook data.

I use the DOM insepector to checkout the DOM of the button code, and it seems like whitespace maybe is the problem. However, i have removed whitespace from the HTMLdata string, and that's not fixing the problem.

did i forget something silly? LOL

i'm using FireFox 3.5 to develop this App. So obviously this will not work with anything other than Gecko Based browsers.

here is my HTML code:


<html>
<head>
<script language="JavaScript">
var eBookLibrary = "eBooks.txt";
var SystemPath = "f:" + String.fromCharCode(92)

function Init()
{
// Initialize the eBook reader
document.getElementById("EbookCanvas").style.visibility = "hidden";
document.getElementById("EbookToolbar").style.visibility = "visible";
document.getElementById("FileManager").style.visibility = "visible";



// Load the List of eBooks in the Library
LoadBookList();
}

function UpdateEbookList()
{
// Update the Library of Ebooks
alert("Updating eBook Library");

// Go back to the File Manager, and Reload the List of Ebooks
LoadBookList();
}

function LoadBookList()
{
// This will load the list of books that are available
var EbookList = LoadFromDisk(SystemPath + eBookLibrary);
var EbookListArray = EbookList.split(",");

for(var x = 0; x < EbookListArray.length -1; x++)
{
// Strip the Filename Extension off of the eBook File Name
// The Name of the Book is always the first Index in the Array
var BookName = EbookListArray[x].split(".");
// Remove the weird whitespace - it screws things up...i think...
BookName[0] = BookName[0].replace(/(^\s*|\s*$)/g, "");

var HTMLdata = HTMLdata + "<input type='button' value='" + "FirstBook" + "'" + " onClick=LoadEbook('" + EbookListArray[x] + "');><br>";
}

// For some ****ed up reason the first string always generates an 'undefined' even though it's nonsense
// So just delete that from the HTMLdata string, because it's just ugly - LOL
HTMLdata = HTMLdata.replace("undefined", "");
HTMLdata = HTMLdata.replace("", " ");

// Write the HTML data to the DIV
document.getElementById("FileManager").innerHTML = HTMLdata;
}

function LoadEbook(EbookName)
{
// Hide the File Manager and Show the Ebook Canvas
document.getElementById("FileManager").style.visibility = "hidden";
document.getElementById("EbookCanvas").style.visibility = "visible";
document.getElementById("EbookToolbar").style.visibility = "visible";

// Load the Ebook content into the Ebook Reader Pannel

var EbookContent = LoadFromDisk(SystemPath + EbookName);

document.getElementById("EbookCanvas").innerHTML = EbookContent;
}

function LoadFromDisk(filePath)

}
catch(e)

//alert("Exception while attempting to load\n\n" + e);
return(false);

return(null);

Hi all,

I hope someone can advise whether such a script exists for what am wanting to do. From time to time, I need to send password information or login details and password information to some users.

At the moment, am doing it via email with a subject named FYI and the body of the email basically just contain the login and the password or in some case, just the password.

What am wanting to know is whether I can put these information into a HTML file which contains an obfuscated Javascript with a button that a user will click that will prompt for his login information and then will display the password.

In its simplest form, I guess I am looking for a Javascript that will obfuscate a HTML file that contains the password. Anyway, hopefully someone understand what am looking for.

I found some website that offers such service as obfuscating a HTML file but am hoping it can be done via a Javascript so it is at least "portable" and I do not have to be online.

Any advice will be much appreciated. Thanks in advance.

Hey everyone here is my code for looking up a city, and state by zip code. I am getting no errors and i believe it should work, but the code does not seem to want to function. Any ideas?

Hi guys.. I really need a bit of help.. is anyone looking at this good with JS?
