JavaScript - Changing File Paths

I can get this code to take two separate sections of a file which are not beside each other and write them into another file. It always comes up as a single full line of the code instead of the sections I want. The code includes the student number first name last name and three results of assignments. I want the code to write the student number and three results of all the students into a file and then work out the average of the student results. Can you help?

Code:

 try{                    
               while (in.hasNextLine())
               {
                  String line = in.nextLine();
                  out.println( line);
                  int i=0;
                  if(!Character.isDigit(line.charAt(i)))  { i++; }
                  studentStringNumber = line.substring(0, i);
                  String stringResult = line.substring(i);
                              	
                  studentStringNumber = studentStringNumber.trim();
                  stringResults = stringResults.trim();
                  double stringResultsValue = Double.parseDouble(stringResults.trim());
                  stringResults = in.nextLine();
                              	
                                 
                  studentStringNumber = in.nextLine();
                  studentNumber = Integer.parseInt(studentStringNumber);
                  if(in.hasNextInt())
                  {
                     int value = in.nextInt();
                  }
               						 					   
                  results = Double.parseDouble(stringResults); 
                  if(in.hasNextDouble())
                  {
                     double value = in.nextDouble();
                  } 
               						               	
                            	
                  Scanner lineScanner = new Scanner(line);
                  studentStringNumber = lineScanner.next();
                  while(!lineScanner.hasNextDouble())
                  {
                     studentStringNumber = studentStringNumber+ " " +lineScanner.next();
                  }
                  stringResultsValue = lineScanner.nextDouble();     
               }
            }

Hi,

Can someone tell me what I am doing wrong. Script works on the first attachment but not the other two?

Code:

<script type="text/javascript" language="JavaScript"><!--
function ExtensionsOkay() {
var extension = new Array();
var fieldvalue = new Array();
fieldvalue[0] = document.customApp.attachment_1.value;
fieldvalue[1] = document.customApp.attachment_2.value;
fieldvalue[2] = document.customApp.attachment_3.value;
extension[0] = ".doc";
extension[1] = ".docx";
extension[2] = ".txt";
extension[3] = ".pdf";


// No other customization needed.
for(var f = 0; f < fieldvalue.length; f++) {
var thisext = fieldvalue[f].substr(fieldvalue[f].lastIndexOf('.'));
for(var i = 0; i < extension.length; i++) {
	if(thisext == extension[i]) { return true; }
	}
alert("Your upload field " + f + " contains an unapproved file name.");
return false;
}
}
//--></script>

Code:

<img src = "/images/boats/large/my-red-pepper---8019812411a.jpg" width = "690" height = "350" id = "main_image"  />    <div id = "gallery_thumbs">

        </div>
        </div>

Why isn't this working? document.getElementById('main_image').src=this.href;return false;
I originally had this:

Code:

$('#sliding_thumbs a').click(function()
    {
        $('#main_image').attr('src',this.href);
        return false;
    })

but that didn't work so I put the onclick inline and it still isn't working but I can't fathom why. I have confirmed that the #main_image is being detected correctly (by alerting the src) and that the this.href part contains the url of an image but nothing happens. There is no error and the large image doesn't load in the same window (so the return false part is working!)

I have this script where people can pick a price and pick quataty. i want it to be only one price and let the person input quatity them selves, how can this be done?



Thanks in advance

Does anyone know how to accomplish this? I got the html file to show but none of the text in the file will show.

Hello all, I am new here and have a question about a AP Div I am using as a dropin. It drops in when the page loads and I would like it to only drop in if a visitor clicks a link I designate as the dropin link. Can someone please tell me how to accomplish this? I am pasting in the js file and I will also need to know how to set up the "a href" link to call the dropin! Thanks is advance for any help you may give!

Code:

// JavaScript Document

var ie=document.all
var dom=document.getElementById
var ns4=document.layers
var calunits=document.layers? "" : "px"

var bouncelimit=32 //(must be divisible by 8)
var direction="up"

function initbox(){
if (!dom&&!ie&&!ns4)
return
crossobj=(dom)?document.getElementById("dropin").style : ie? document.all.dropin : document.dropin
scroll_top=(ie)? truebody().scrollTop : window.pageYOffset
crossobj.top=scroll_top-250+calunits
crossobj.visibility=(dom||ie)? "visible" : "show"
dropstart=setInterval("dropin()",50)
}

function dropin(){
scroll_top=(ie)? truebody().scrollTop : window.pageYOffset
if (parseInt(crossobj.top)<100+scroll_top)
crossobj.top=parseInt(crossobj.top)+40+calunits
else{
clearInterval(dropstart)
bouncestart=setInterval("bouncein()",50)
}
}

function bouncein(){
crossobj.top=parseInt(crossobj.top)-bouncelimit+calunits
if (bouncelimit<0)
bouncelimit+=8
bouncelimit=bouncelimit*-1
if (bouncelimit==0){
clearInterval(bouncestart)
}
}

function dismissbox(){
if (window.bouncestart) clearInterval(bouncestart)
crossobj.visibility="hidden"
}

function truebody(){
return (document.compatMode && document.compatMode!="BackCompat")? document.documentElement : document.body
}


window.onload=window.setTimeout(initbox,5000);

Hey all,

for some reason, I can't get the margin-top property to change
using
Code:

jQ(this.centerPiece).attr('marginTop', this.imgSrcs[ this.srcs[5] ].top);

also tried
jQ(this.centerPiece).attr('margin-top', this.imgSrcs[ this.srcs[5] ].top);

any help would be great

I'm working at masking my fantasy football site hosted by my provider onto my own subdomain, since they can't allow me point a dns at their servers.

I did manage to mask the webaddress to my sub doman with a php script. But it also only masks the initial visit, and th link name.

And now i'm trying to learn how mask the various url/links in the menus.

As I little about javascript, can someone show me a way to mask the url address when a user mouses over them? The links themselves wont' change, I'm just trying to mask the link names on the mouseover to look like their on my own domain.

Hope that all made some sense

I go to a page and have this in the URL

http://beta.pigskinempire.com/boxscore.asp?w=6&s=5&yr=

I want to create a link on that page that when you click it it changes the URL to

http://beta.pigskinempire.com/game.asp?gnum=6&gslot=5

as you can see the numbers 6 and 5 are about the only things that are similar in the substring. I will have this on multiple pages so it will be taking different numbers from the same spots of the URL and plugging them into the new URL into the correct location.

Thank you very much if you can help me, I am thinking regEx will be needed but I am not very comfortable with it. Thanks again.

hi all,

when key pressed, in IE i can use this code:

event.keyCode=somenumber;

and it works. Is this possible in Netscape - Firefox - ..... ?

I need to controll the input, I want to allow users to use only keys I want them to use.

Thanks

ok i have a script which will make a copy of the html in a div and place it into another div the problem with this it creates a duplicate element with the same id so what i want to know is can i create a new id based off old ids using a generic type script

Code:

function scope(e)
{
var popin = document.getElementById('popin');
popin.innerHTML = "<div class='container'>"+e.innerHTML+"</div>";
popin.style.display = "block";
}

this code is designed for taking content in a small div and placing it into a larger div to increase the viewing area

so what i would need is sumthing that can look for
Code:

id="sum text"

and maybe amend it to
Code:

id="sum textP"

or sumthing to that extent if sum1 could point me in the right direction that would be great if my post is not clear enough just ask me to be more specific or sumthing and i will see what i can do to try and make it more clear if needed

If you wanted to change an ids onclick would int you just do this

document.getElementById("").onclick = "";

Is there a way to do it?

Ok so i'm trying to write a Greasemonkey script to change all the hrefs on a single page.

The href by default looks like this:

Code:

<a href="javascript:get('246154895')" class="postid">ID</a>

What i'm trying to do is make the number from get() appear in stead of "ID".
How should i get this done?

I started up with this:

Code:

var posts = document.getElementsByClassname('postid');

for (i=0; i<posts.length; i++) {
	//Replacing
}

But i doubt it will work, since there are other items with the class "postid" that aren't related to these tags i'm trying to change.

P.S. I'm new to JS so yeah :P

How can i edit the following html/javascript so that when a user submits the form the element with id #container is updated with the value from #name

<form action="" method="post" name="form_name" id="form_name" onsubmit="return update_name(this)">
<fieldset>
<label for="your_name">Enter Your Name</label>
<input type="text" name="your_name" id="your_name" />
<input type="submit" />
</fieldset>
</form>
