JavaScript - Need Help Replacing Part Of Javascript

I'm sorry this is simple, but:

Code:

function printInput(f){
  var ifr = window.frames['printFrame'];
  var v1=readCookie('lesson');
  if (v1==1){v2='WORKNOTEPAD1'}
  if (v1==2){v2='WORKNOTEPAD2'}
  if (ifr){
     ifr.document.getElementById('content').innerHTML=f. v2 .value.replace(/\n/g,'<br />');
     ifr.focus();
     ifr.print();
  }
  else { something }
}

In this line:

Code:

ifr.document.getElementById('content').innerHTML=f. v2 .value.replace(/\n/g,'<br />');

How can I make it stop erroring and act as if the "v2" were, say, "WORKNOTEPAD2"?

If the line contains the string it all works fine.

It must be so simple...

Hey guys...

Basically I need a function that will remove numerous elements from a page based on their class. I then also need a function to bring those elements back afterwards. If anyone is wondering, I'm trying to add buttons to remove/add images.

Thanks!

Hi,

I am quite new to JS and is currently building a website with a little of JS Function. Ok, so I have a Page tat consists of 10 images. Each images when on mouse over, will display a larger version on the images, using JS(onmouseover).

Then, I will have a next button that will replace all the images, using Ajax, which means my page will not be reloaded. The problem comes here when I have to replace all the onmouseover effect.

I can replace all the thumbnails without problem, but the onmouseover I have problem replacing. Is there anyway that I can dynamically replace all the onmouseover?

Any help will be appreciated. Thanks

Hi,

I know how to replace all the + signs in a url string by spaces, like this:

newstring=oldstring.replace(/[+]/g," ");


but how do I replace a substring by a comma easily? This doesn't do it:

newstring=oldstring.replace(/[&menuitems]/,",");


Thanks in advance for any help.

I have 16 links on a page, when each link is clicked, I need to change text that is on the page.

This is Page 1

link 1 This Is Page 1
link 2 This is Page 2
...
link 16 This is Page 16

How can I do this?
Excuse my ignorance, this is my first JS project

I'm a bit of a Javascript noob, so please bear with me!

I'm trying to create a piece of code that will check a webpage and replace any instances of a specific line of HTML with another line of HTML.

The code I have so far doesn't work, but I have a feeling that's down to my awful Javascript skills!

For example, in the following code I'd want to replace all instances of <li><a href="index.pdf">Index</a></li> with <li><a href="contents.pdf">Contents</a></li>

Code:

<div id="downloads">
    <p>Please click on your downloads below:</p>
    <ul>
        <li><a href="index.pdf">Index</a></li>
        <li><a href="chapter1.pdf">Chapter 1</a></li>
        <li><a href="chapter2.pdf">Chapter 2</a></li>
        <li><a href="chapter3.pdf">Chapter 3</a></li>
        <li><a href="credits.pdf">Credits</a></li>
    </ul>
</div>

The Javascript I have so far is:

Code:

<script type="text/javascript">

var aEls = document.getElementsByTagName('a');
for (var i = 0, aEl; aEl = aEls[i]; i++) {
	aEl.href = aEl.href.replace('index.pdf','contents.pdf');
			
}

Obviously this is meant to just replaces the a href elements, but I got a bit stuck after this!

Any pointers would be much appriciated.

Hey folks. I currently have a PTZ camera that is taking screenshots every minute (or so) and sending a copy of that image (overwriting the previous one) to my website. Basically, the visitors to the website will be greeted with a live screenshot. The problem is if the visitor hits the website at just the right time, the screenshot won't be loaded completely while the 2nd most screenshot is being overwritten... creating an empty image load (the dreaded red X). What I am looking to do with Javascript is to be able to load a generic image in the scenario in which no image loads. Is that possible?

I tried doing something like the following and onload-ing it, but it wouldn't work. Any help would be appreciated. Thanks!

Code:

<script type="text/javascript">
		<!--		
		function replaceSrc() {      
			var images = document.getElementsByTagName('img');      
			
			for(var i = 0; i < images.length; i++) {         
				var img = images[i];          
				if(img.src.length == 0) {             
					img.src = 'images/garbage.gif';         
					}     
				} 
			}   			
			
		-->
</script>

Ok, i have a javascript that creates a table then appends it to an empty div. This works fine in FF, however it fails to work in IE8.
[edit]
I have decided to post the entire code since I wasn't having any luck getting any suggestions. Maybe now someone can help me out.

Code:

function createTable() {
var machine = document.Catalog.machine.value;
var dSearch = document.Catalog.dSearch.value;
var section = document.Catalog.section.value;
var x = xmlDoc.getElementsByTagName('record');
var y = xmlDoc.getElementsByTagName('data');
var newEl = document.createElement('TABLE');
newEl.className = 'resultsTab';
var tmp = document.createElement('TBODY');
newEl.appendChild(tmp);
var row = document.createElement('TR');
var n = 1;
var headings = new Array("Col1", "Col2", "Col3", "Col4", "Col5");
var dcount = 0;
//for (t=0;t<10;t++) {
for (t=0;t<y[0].childNodes.length;t++) {  
	if (y[0].childNodes[t].tagName == "record") { // it is required for FF to work properly
		dcount++;
	}
}
if (document.Catalog.thumbImg[0].checked) {  
	var container = document.createElement('TH'); 
	var theData = document.createTextNode("Pic"); 
	container.className = "topline1"; 
    container.appendChild(theData);
    row.appendChild(container);
}
for (h=0;h<headings.length;h++) {
     var container = document.createElement('TH');
     var theData = document.createTextNode(headings[h]);
	 container.className = 'topline' + n;
     container.appendChild(theData);
     row.appendChild(container);
	 n++;
}
tmp.appendChild(row);
switch (searchtype) {
    case 1:
	var objRegex = new RegExp(machine);
    break;
    case 2:
	var objRegex = new RegExp(section, "i");
    break;
    case 3:
	var objRegex = new RegExp(dSearch, "i");
	break;
    default:
	document.getElementById("replaceTxt").innerHTML = "<p>There was an error processing your request.</p>";    
}
var rowColor = 1; 
var noResult = "false"; 
for (i=0;i<dcount;i++) {
	var row = document.createElement('TR');
	var searcharr = new Array();
   	for (j=0;j<x[i].childNodes.length;j++) {  
    	if (x[i].childNodes[j].nodeType != 1) continue;  
		searcharr.push(x[i].childNodes[j].firstChild.nodeValue);
	}
	var searchstrg = searcharr.toString();
	if (searchstrg.match(objRegex)) { 
		var t;
	 	var m=1;
		if (document.Catalog.thumbImg[0].checked) { 
			var pn = "images/"+searcharr[2]+".jpg"; 
			var container = document.createElement('TD'); 
			var refLink = document.createElement("A");
			refLink.setAttribute('href', "javascript:viewImg(\""+pn+"\")");
			var imgHolder = document.createElement("IMG"); 
			imgHolder.setAttribute("src", pn); 
			imgHolder.style.height = "75px";  
			refLink.appendChild(imgHolder); 
			container.appendChild(refLink);   
			container.className = "img"+rowColor; 
			row.appendChild(container);
		}
		for (t=0; t<searcharr.length; t++) {
	    	container = document.createElement('TD');
    		var theData = document.createTextNode(searcharr[t]);
			container.appendChild(theData);
			container.className = 'line' + rowColor + '_' + m;
			row.appendChild(container);
			m++;
		}
		tmp.appendChild(row);
		rowColor == 1 ? rowColor++ : rowColor--;
		document.getElementById("replaceTxt").innerHTML = "";
		document.getElementById("replaceTxt").appendChild(newEl);
		noResult = "true";
	} 
}
if (noResult=="false") { 
	document.getElementById("replaceTxt").innerHTML = "<h3>Sorry, there was no match to your search. &nbsp;Please try again</h3>";
}
}

xmlDoc is the xml object from my import xml function. it is working correctly. IE does not give any JS errors, it just does nothing. If I put text in the
Code:

document.getElementById("replaceTxt").innerHTML

field, IE displays the text in the correct spot so I know the code is working. I also verified the data is being written correctly to "newEl" via IE 8 debugger. IE just does not want to append the newEl child to the <div> tag. This is where I assume the problem is.

Hi Guys/Gals

I am trying to do a small website for our family to keep track of each other's home address and etc..

using asp for the codes .. (its been ages since i indulge myself)

i have 2 forms

in which in FormA, i will key in the following address

666, ST Avenue
#03-09
Anchor View Residence
123456

when i click on submit
it shows this on FormB

666, ST Avenue #03-09 Anchor View Residence 123456

my question is

how do i get it to be shown as

666, ST Avenue
#03-09
Anchor View Residence
123456

in FormB

in my formB.asp, for the particular code, all i wrote was Code:

{Form.address}

I am in need of advise, have been stuck here for the past 1 day, not knwing wat to start or how to start.

Thank you

Code:

var bakaBanner;
bakaBanner = document.getElementById('head');
if (bakaBanner) {
var str=/\/images\/banners\/[A-Za-z0-9_]+.[a-z]+/;
document.write(str.replace(/\/images\/banners\/[A-Za-z0-9_]+.[a-z]+/, "http://img218.imageshack.us/img218/5904/revyblacklagoon1.png"));
}

Alright, here's the deal... This is a script to be used in Greasemonkey. The page this is for changes their banner every 5 minutes, the name changes and it could be either jpg or png.

I'm fairly certain my regex itself:
\/images\/banners\/[A-Za-z0-9_]+.[a-z]+
Is correct... Here's an example of what it's looking through:

Code:

<div id="head"  style="background-image: url(/images/banners/kiminitodoke.jpg);" >
	<div id="header_left">
		<div id="rss">

My guess is that it has something to do with this line:
document.write(str.replace(/\/images\/banners\/[A-Za-z0-9_]+.[a-z]+/, "http://img218.imageshack.us/img218/5904/revyblacklagoon1.png"));

I'm new with Javascript, so I don't really understand why it's not working... :/

Hi,
I have youtube link saved as a variable with value:

PHP Code:
http://www.youtube.com/watch?v=oOzuBOefL8I&feature=topvideos 


And I need to get a part of this link which I could use later:

The part would be
PHP Code:
oOzuBOefL8I 


It would be great to do it with javascript... Because I have url generated like this one:

PHP Code:
httpObject.open("GET", "../talpinimas.php?id=reklama&paveikslelis="
                        +document.getElementById('paveikslelis').value+"&pavadinimas="
                        +document.getElementById('pavadinimas').value+"&url1="
                        +document.getElementById('url1').value+"&url1name="
                        +document.getElementById('url1name').value+"&komentaras="
                        +document.getElementById('komentaras').value+"&nick=<?php echo $nick?>"
                        , true);

and I want to send just THE PART (oOzuBOefL8I) to my talpinimas.php page.

If you haven't understood something or need more info ask... Thanks

I've got an idea for simplifying my code and avoid a bunch of switch functions but don't know how, though I assume it's possible.

How do I write a function to change/insert only part of an img src?

in other words something along the lines of

if url contains: "/folder1/folder3/";

change this to: "/folder1/ folder2 /folder3/";

My problem is relates to getting part of the text from a div, then pass this on to a variable which then acts upon it.
This is a short summary in detail:
http://jsfiddle.net/defencedog/W9Fsw/
Above simulates a Forum like environment (PHPBB3). here user can't insert html in posts thus a customised BBcode ([doc])is made in which is placed the required src attribute, unique to every SCRIBD document.
The goal is to get the text within the two [doc] & that will be something like (discarding the two BBCodes)
Code:

src="http://www.scribd.com/embeds/2942002/content?start_page=1&view_mode=list&access_key=key-sxlnrfvqu5s22kzi5xb"

then pass it on as a variable named src, which will then replace the contents to achieve desired output.
Notice the two problems
1] how do I select the div upon which the action is to take place I.e that contains [doc]. Remember there occurs other divs as well in a posted message?
2] How do I select the desired text?

Plz do giv me some suggestions

I'm trying to figure out how to split a url variable... I tried these two ways, with an alert to see my result, but I'm not getting anything. Suggestions?

Code:

        function() {

            myURL = "http://www.test.com/folder1/folder2/someone"

           var partsA = myURL.split("//");
           var parts = partsA[1].split("/");

           alert(parts[2]);

        }

Code:

function() {

       myURL = "http://www.test.com/folder1/folder2/someone"

            var parts = myURL.split('/');
            var result = parts[parts.length-2] + '/' + parts[parts.length-1];

           alert(result);

        }
