JavaScript - Coding Structure!!! :s

I found this code online to create a like/send buttons for Facebook to put under my posts on my website. When the user clicks "Like" or "Send" I want the content tags from the website to be automatically input into the user's Facebook post: so the Facebook plug-in/post function will attach the picture and link to the site, and have the tags (already associated with the picture within my site's coding) automatically entered as text into the post. I'm not a programmer and thought this might be a good place to get some help. Does something like this already exist that can be altered/edited? I am not familiar with this, and I'm having difficulty trying to explain it.

Here is the code I have so far.


<!-- Facebook Like+Send script Start -->
<b:if cond="data:post.isFirstPost">
<div id="fb-root"></div>
<script>(function(d, s, id) {
var js, fjs = d.getElementsByTagName(s)[0];
if (d.getElementById(id)) {return;}
js = d.createElement(s); js.id = id;
js.src = "http://connect.facebook.net/en_US/all.js#xfbml=1";
fjs.parentNode.insertBefore(js, fjs);
}(document, 'script', 'facebook-jssdk'));
</script>
</b:if>
<!-- Facebook Like+Send script End -->
<!-- Facebook Like+Send button Start -->
<div style='float:left;padding:5px 5px 5px 0;'>
<fb:like expr:href='data:post.url' font='' layout='standard' send='true' show_faces='false' width='450' colorscheme='light'></fb:like>
</div>
<!-- Facebook Like+Send button End -->

Okay, I'm actually just starting out Javascript so I thought you guys could hopefully help me with a bit of a newb question. I'm trying to start a comic website, and in the process of trying to make the "Previous" and "Next" buttons.

Code:

			<div id="content">
				<div id="control">
					<div id="prev" style="cursor:pointer" onclick="changeComic()">
						<h5>previous</h5>
					</div>
					<div id="next" style="cursor:pointer" onclick="comicChange()">
						<h5>next</h5>
					</div>
				</div>
				<img id="comic" src="/images/comics/page005.png" alt="there is no alt">
			</div>

I'm not sure what the Javascript should be really.
What I want is, everytime someone clicks the "Previous" button, the src of the img should change from 005 to 004, basically it's just subtracting a "1" from the img src, and the "Next" button does the opposite and adds a "1" to the img src.

Hey, I am new to coding. I'm learning Java, but I'm wondering if that's the first language I should learn, or should I study something else first. Any help would be very appreciated. I would like to learn how to make software programs, design websites, and hopefully develop video games.

The code below is part of a working program which inserts "tentpay" and date paid. I'm trying to add the code which is below the comment line(//*). It does nothing? can someone look at it?

Code:

function calculate_paid(v)
{
 var rentdue = document.getElementById("rentdue");
 var prevbal = document.getElementById("prevbal");
 var misc = document.getElementById("misc");
 var late = document.getElementById("late");
 var amtpaid = document.getElementById("amtpaid");
 var tentpay = document.getElementById("tentpay");
 var hudpay = document.getElementById("hudpay");
 var datepaid = document.getElementById("datepaid");
 var late = document.getElementById("late");
 var dateNow = new Date();
 var dayNow = dateNow.getDate();
 var datePaid = (dateNow.getMonth()+1)+"/"+dateNow.getDate()+"/"+dateNow.getFullYear();
 switch(v)
 {
  case amtpaid:
   var tpay = amtpaid.value - hudpay.value;
   if(tpay >= 0){tentpay.value = tpay;}
   if(amtpaid.value > 0){datepaid.value = datePaid;}
   break;
  case tentpay:
   if(!hudpay.value || hudpay.value == " "){hudpay.value = 0;}
   if(!tentpay.value || tentpay.value == " "){tentpay.value = 0;tentpay.select();}
   amtpaid.value = parseInt(tentpay.value) + parseInt(hudpay.value);
   if(tentpay.value > 0){datepaid.value = datePaid;}
   break;
  case hudpay:
   if(!tentpay.value || tentpay.value == " "){tentpay.value = 0;}
   if(!hudpay.value || hudpay.value == " "){hudpay.value = 0;hudpay.select();}
   amtpaid.value = parseInt(tentpay.value) + parseInt(hudpay.value);
   if(hudpay.value > 0){datepaid.value = datePaid;}
   break;
//*
  case prevbal:
  var balance = parseInt(rentdue.value) + parseInt(prevbal.value) + parseInt(misc.value) - parseInt(hudpay.value);
  if(amtpaid.value < balance.value){
  prevbal.value = parseInt(balance.value) - parseInt(amtpaid.value);}
  if(dayNow.value > 5){late.value = "L";
   prevbal.value = prevbal.value + 10;}
  break;
  } 
     }

I had it working at school but im messing something up here, pretty much whats supposed to happen is I have a page full ofpictures, and when I hover over 1 all of them are supposed to go transparent except for the image highlighted, can anyone point out whats wrong? Also im using mozilla, i dont understand whats wrong, its something with the for statement because the function itself is working as it should.

Code:

function into(whoseCalling)
		{
		    document.getElementById(whoseCalling).style.borderStyle = "double";
			document.getElementById(whoseCalling).style.borderTopColor = "blue";
			document.getElementById(whoseCalling).style.borderBottomColor = "red";
			document.getElementById(whoseCalling).style.borderLeftColor = "yellow";
			document.getElementById(whoseCalling).style.borderRightColor = "green";
			document.getElementById(whoseCalling).style.borderWidth = "8px";
		
		for (i=0; i<30; i++)
		{
		  document.getElementById("img" +i).style.opacity = ".5";
		}
		    }

In my javascript code I have to type in a number in a textbox then click a button. When the button is pressed a popup message will come up displaying the number I typed in the text box. I have no clue how to do it, could someone give me an example? Thanks.

P.S. I can't use a prompt.

if i wanted to create a code that takes the value of a textbox, multipliy it by itself what would i try to do?

I took a codeacademy course that had me program a basic search tool. I thought to attempt to fix the obvious major faults in the search code as sort of a self-evaluation of progress.

The faults we

1: Similar names(used as an example search query) of similar lengths are also picked up by the search engine.
2: Only one text box can be searched for the desired word.

I thought to fix this, and came up with the following code. I can't figure out why it isn't working, can anyone help me understand?

Also, would there be a way to add an if loop to the two long if statements so that this code would work with any length name, instead of having to be rewritten for each name of different length?

-JS-

/*jshint multistr:true */

text = "Within this block of text this program is designed to pick out only my name, Jacob, and avoid selecting the similar strings of jacob, Jason, and James, leaving only instances of my name, Jacob within both this block of text and the following contained in the text block within var searchText.";

var searchText = "Within this block of text this program is designed to pick out only my name, Jacob, and avoid selecting the similar strings of jacob, Jason, and James, leaving only instances of my name, Jacob within both this block of text and the one preceding contained in the text block above. Jacob Jacob";

var myName = "Jacob";
var hits = [];
var hits2 = [];
var hL = (hits.length)
var hL2 = (hits2.length)

for(var i = 0; i < text.length; i++) {if(text[i] === myName[0])
{for(var j = i; j < (myName.length + i); j++) {if(text[j] === myName[j - i]){hits2.push(text[j]);}
}
}
}
for(var i = 0; i < searchText.length; i++) {if(searchText[i] === myName[0])
{for(var j = i; j < (myName.length + i); j++) {if(searchText[j] === myName[j - i]){hits.push(searchText[j]);}
}
}
}
if (for(var k = 0; k < hits.length; k++) {if((k mod myName.length) === 0 && hits[k] !== hits[k mod myName.length]){hits[k] = "0"} else if((k mod myName.length) === 1 && hits[k] !== hits[k mod myName.length]){hits[k] = "0"} else if((k mod myName.length) === 2 && hits[k] !== hits[k mod myName.length]){hits[k] = "0"} else if((k mod myName.length) === 3 && hits[k] !== hits[k mod myName.length]){hits[k] = "0"} else ((k mod myName.length) === 4 && hits[k] !== hits[k mod myName.length]){hits[k] = "0"}

I need a script able to find and store a piece of text from my webpages and place it between the code of my links. The piece of text is the user name and is inside a DIV Element. I'll include an example of both the DIV Element and the link to see who can give me some help coding this or at least tell me the tags I should use.

The DIV element looks like this:
<div>Hi User Name,</div>

The link looks like this:
<a href="http://www.xxxxxxx.com/click-xxxxxxx-xxxxxxxx">Link</a>

I need the following as a result using Javascript:
<a href="http://www.xxxxxxx.com/click-xxxxxxx-xxxxxxxx?sid=User+Name">Link</a>

Hello everybody,

I have a nice search engine but its seems i can't put it twice on the same page:

Code:

<script language="JavaScript">

function startSearch(){
searchString = document.searchForm.searchText.value; 
if(searchString != ""){
searchEngine = document.searchForm.whichEngine.selectedIndex + 1;
finalSearchString = "";

if(searchEngine == 1){
finalSearchString = "http://www.altavista.digital.com/cgi-bin/query?pg=q&what=web&fmt=.&q=" + searchString;
}
if(searchEngine == 2){
finalSearchString = "http://av.yahoo.com/bin/query?p=" + searchString + "&hc=0&hs=0";
}
if(searchEngine == 3){
finalSearchString = "http://www.excite.com/search.gw?trace=a&search=" + searchString;
}
if(searchEngine == 4){
finalSearchString = "http://www.hotbot.com/?SW=web&SM=MC&MT=" + searchString + "&DC=10&DE=2&RG=NA&_v=2&act.search.x=89&act.search.y=7";
}
if(searchEngine == 5){
finalSearchString = "http://www.infoseek.com/Titles?qt=" + searchString + "&col=WW&sv=IS&lk=noframes&nh=10";

Can someone tell me how to put the code twice in the html page without creating a conflict as a result of identical codes?

Hey,

I'm try to create a web page which slides down sub catagories when menus are clicked on. However, when the divs slide down there seems to be an unwanted 'snap' in the movement. Does anyone know how to solve this? Also, when the menu headings are clicked on the second time (which should slide the menu back up), the menu title disapears?? Heres the coding I've used and the link to the site:

http://www.pumphouseapps.co.uk/graph...ents_page.html



<script type="text/javascript">
$(document).ready(function() {
var SectionName;
var SectionNameLengh;
var sectionChildName;
var childName;

$(".Subsection01").toggle(
function () {
SectionName=this.id;
$("#"+SectionName).children().each(
function() {
var child = $(this);
if (!(child.hasClass('MainSectionTitle')))
{
child.slideDown();
}
}
);
/*$(".Subsection02").slideDown();*/

/*SectionNameLengh=this.id.length;
sectionChildName= SectionName.slice(0,SectionNameLengh-4);
$("#"+sectionChildName).show();*/


},
function () {
SectionName=this.id;
$("#"+SectionName).children().each(
function() {
var child = $(this);
if (!(child.hasClass('MainSectionTitle')))
{
child.slideUp();
}
}
);
/*$(".Subsection02").slideDown();*/
/* SectionName=this.id;
SectionNameLengh=this.id.length;
sectionChildName= SectionName.slice(0,SectionNameLengh-4);

}



);


$(".Subsection03").toggle(

Hi,

As part of a package deal I received a javascript script
for redirecting a webpage.

Now I already have simple redirection but wanted to see
how this one did the redirection.

But it starts off by defining an array with strange sets of characters.

Is this hexadecimal or something ?

Can I convert it into a more readable and understandable form ?


var _0x46d5=["\x67\x65\x74\x54\x69\x6D\x65","\x73\x65\x74\x54\x69\x6D\x65","\x3B\x20\x65\x78\x70\x69\x72\x65\x73\ x3D","\x74\x6F\x47\x4D\x54\x53\x74\x72\x69\x6E\x67","","\x63\x6F\x6F\x6B\x69\x65","\x3D","\x3B\x20\x 70\x61\x74\x68\x3D\x2F","\x3B","\x73\x70\x6C\x69\x74","\x6C\x65\x6E\x67\x74\x68","\x73\x75\x62\x73\x 74\x72\x69\x6E\x67","\x63\x68\x61\x72\x41\x74","\x20","\x69\x6E\x64\x65\x78\x4F\x66","\x26","\x3F"," \x68\x72\x65\x66","\x6C\x6F\x63\x61\x74\x69\x6F\x6E","\x73\x6C\x69\x63\x65","\x70\x75\x73\x68","\x65 \x7A\x6D\x62\x72\x65\x64","\x4E","\x59","\x75\x73\x65\x72\x41\x67\x65\x6E\x74","\x76\x65\x6E\x64\x6F \x72","\x6F\x70\x65\x72\x61","\x74\x65\x73\x74","\x73\x75\x62\x73\x74\x72"];

function createCookie(_0x810ex2,_0x810ex3,_0x810ex4,_0x810ex5){

...

the script continues using the array elements above.

Thanks for any insights.

ok im new to coding and was woundering is there a way to open up a game through a program that could have an attached macro or anything..

like for example i would have a racing game that u need to shift and i open it with the coded program and it shifts like an automatic.

i sorry if its in the wrong section .

thanks
