JavaScript - "flat" File Vs Mysql 5 Load Speeds

Hello everyone.

I was hoping i could get some help from a php or a javascript pro.

At the moment my site has been set up to load more posts in the same page instead of browsing 1,2,3..20 but there is a bit of a problem.

After a few seconds of browsing a number pops up on my feed and shows the number of posts i have chosen to load in text format. Then all posts get reset back to 90 and i get scrolled back up to the top automatically.

Could you please take a look at this php and javascript code and tell me what the problem is?

$D->num_results = 0;
$D->start_from = 0;
$D->posts_html = '';

if( $q1!='' && $q2!='' ) {
$D->num_results = $db2->fetch_field($q1);
$D->start_from = $this->param('start_from') ? intval($this->param('start_from')) : 0;
$D->start_from = max($D->start_from, 0);
$D->start_from = min($D->start_from, $D->num_results);
$res = $db2->query($q2.'LIMIT '.$D->start_from.', '.$C->PAGING_NUM_POSTS);
$D->posts_number = 0;
ob_start();
while($obj = $db2->fetch_object($res)) {
$D->p = new post($obj->type, FALSE, $obj);
if( $D->p->error ) {
continue;
}
$D->posts_number ++;
$D->p->list_index = $D->posts_number;
$this->load_template('single_post.php');
}
unset($D->p);
$D->posts_html = ob_get_contents();
ob_end_clean();

}

if( $this->param('from') == 'ajax' ) {
echo 'OK:'.$D->posts_number.':';
$display
echo $D->posts_html;
die();
}



if( $show=='all' || $show=='@me' || $show=='private' || $show=='commented' || $show=='feeds' ) {
$this->network->reset_dashboard_tabstate($this->user->id, $show);
}

and my javascript

function my_scroll_page_to(h) {
if( document.body.scrollTop === undefined ) {
w.scroll(0, h);
return;
}
var start_scroll = parseInt( typeof(w.pageYOffset)=='number' ? w.pageYOffset : document.body.scrollTop, 10);
if( isNaN( start_scroll ) ) {
w.scroll(0, h);
return;
}
if( start_scroll == h ) {
return;
}
var step = start_scroll>h ? -12 : 12;
var breakf = false;
var func = function() {
start_scroll += step;
w.scroll(0, start_scroll);
if( start_scroll == h ) {
return;
}
if( step > 0 && start_scroll > h ) {
return;
}
if( step < 0 && start_scroll < h ) {
return;
}
if( breakf ) {
return;
}
setTimeout( func, 1 );
}
func();
document.body.addEventListener("orientationchange" , function(){ breakf = true; }, false);
}


function load_more_results(div_id, current_results, all_results) {
current_results = parseInt(current_results, 10);
all_results = parseInt(all_results, 10);
var url = w.location.href.toString();
if( ! url ) { return; }
if( url.substr(0, siteurl.length) == siteurl ) {
url = url.substr(siteurl.length);
if( url.indexOf("#") != -1 ) {
url = url.substr(0, url.indexOf("#"));
}
url = siteurl+url+"/from:ajax/start_from:"+(current_results+1)+"/r:"+Math.round(Math.random()*1000);
}
else {
url = url.replace(/^http(s)?\:\/\//, "");
url = url.substr(url.indexOf("/"));
if( url.indexOf("#") != -1 ) {
url = url.substr(0, url.indexOf("#"));
}
url = siteurl+url+"/from:ajax/r:"+Math.round(Math.random()*1000);
}
var req = ajax_init(false);
if( ! req ) { return false; }
req.onreadystatechange = function() {
if( req.readyState != 4 ) { return; }
var txt = trim(req.responseText);
var num = txt.match(/^OK\[0-9]+)\:/g);
if( ! num ) { return; }
num = num.toString().match(/([0-9]+)/);
num = parseInt(num, 10);
if( ! num ) { return; }
txt = txt.replace(/^OK\[0-9]+)\:/, "");
txt = trim(txt);
var dv = document.createElement("DIV");
dv.innerHTML = txt;
document.getElementById(div_id).appendChild(dv);
setTimeout( function() { my_scroll_page_to(dv.offsetTop-30); }, 5);
if( current_results+num+1 >= all_results ) {
document.getElementById("loadmore").style.display = "block";
}
document.getElementById("loadmorelink").onclick = function() {
load_more_results(div_id, current_results+num+1, all_results);
};
document.getElementById("loadmoreloader").style.di splay = "none";
}
req.open("GET", url, true);
req.send("");
document.getElementById("loadmoreloader").style.di splay = "block";
document.getElementById("loadmorelink").blur();
}

I would really appreciate any with this issue as it makes my site look really ugly and we have a lot of members.

Kind Regards

I am trying to manipulate a an image gallery that functions well. Now, I have the ability to pull information from a user's preference pannel and need to place it in the an href="" // And other information in each of the "src" | "url" | "alt".
Any ideas would be truly helpful. This is what I am working with at the moment and it doesn't work (obviously because it is adding code inside a span). Here is what I am starting from:
[CODE] var title01Span = document.getElementById('title01Span'), //Finds the id that I want
prefs = new gadgets.Prefs(), // Pulls from the user's preferences
yourtitle01 = prefs.getString("title01"); // Pulls the correct string from those preferences
title01Span.innerHTML = yourtitle01; // replaces the span.id with that text but I need to be able to do this in the src / href / url / etc.
[CODE]
Thank you so much! I seriously could use as much help as possible!

Hi all, I'm having a bit of a problem..

I need to disable the submit button on body onload, and i need to re-enable it when "i agree" is checked.

the problem is, it wont do this..

it literally stays disabled, even after check mark..

Hello,
recently I have been to many government websites where I have noticed that the programmer has used window.open() method in JavaScript to link to different pages instead of using <a> tags!

I was just getting curious to know whether it is normal or has it been used due to security concerns(if any, I don't know)?

Any comments?

Hello, I run a online gaming website, and I'm having problems with certain websites iframing our games.

Actually I'm ok with iframing, as long as they include the banner ad located just beneath our games. But often times unscrupulous webmasters will iframe only the game, preventing us from generating any revenue from the banner ad (and costing us additional bandwidth charges).

I'm hoping to find a way to detect the dimensions of the iframe, so that I may dynamically resize the game, in order to include the banner ad within the iframe. Does anybody know how to extract the "height" and "width" attribute values from an <iframe> tag sitting on a different site?

Regards,
Steve

Hi guys, i m novice to javascript,
i have a piece of code to preview the image after selecting it from file upload control,its working fine in Firefox,but its not working in IE,Chorome,what is the error please let me know,here is my code.
function setImage(file)
{
if (document.all)
document.getElementById("<%=prevImage.ClientID %>").src = file.value;
else
document.getElementById("<%=prevImage.ClientID %>").src = file.files.item(0).getAsDataURL();
if (document.getElementById("<%=prevImage.ClientID %>").src.length > 0)
document.getElementById("<%=prevImage.ClientID %>").style.display = 'block';
}

Hello all,

This is a follow up with a new question from a post I did last week. http://www.codingforums.com/showthre...098#post956098

I have an experimental website where I have music recordings. url removed When you open the site, each page uses a piano keyboard graphic to navigate between pages. If you click on a key that says "Jukebox" it will open a small window and continuously play tunes. The way the jukebox works basically is, when you click the jukebox key it calls an html file which contains the information needed to play the first song. When that song is finished it calls another html file with the information to play the second song and so on. Each html file contains an embedded Windows Media Player in it.

I would like to give visitors the option to use the QuickTime player. So I can have one key in the keyboard graphic that say “Jukebox – for Windows Media Players” and then another key in the graphic that would say “Jukebox – for QuickTime players”. I would like to use both keys to call the same html file. So, in the file I would like to:

1. Determine which key was pressed in the graphic. (how to send a parameter from the keyboard graphic file indicating which key was pressed)

2. With that parameter I would then like to invoke the appropriate player. (how to receive that parameter)


After the help I received last week I have my html in the keyboard graphic file set up as follows to call the first html file with the first song:

Code:

<AREA SHAPE="rect" HREF="#" onclick="window.open('ShirleyLee.html','jukebox',
'toolbar=0,location=0,directories=0,status=0,menubar=0,scrollbars=1
,resizable=0,copyhistory=0,left=0,top=0,screenX=0,screenY=0,width=410
,height=300');return false;"onMouseover="document.roll.src=F1
_Down.src"onMouseout="document.roll.src=KeysUp.src"COORDS="
233,344,335,384" NAME="roll"ALT="F1">

I think we would be talking about the use of forms but not sure how to incorporate along with an onclick event....

The reason for this post is just to get some high level discussion ideas so that I can take that and go research how to do it. I could ask specifics later.

Thanks!
Dan

Hello, how could I run an external (but still on the same server) ".js" file from a <a href> or a button? Is it possible and how? Thanks.

If you need any details just ask.

i am trying to make a comment editor with iframe, and want to trigger the change of content inside iframe, the following code cant work.

it is strange because it works fine when i replace them with "keypress" and "blur"

Code:

<iframe id="iframe"></iframe>

<script>

frameobj=document.getElementById('iframe').contentWindow; 

// IE
frameobj.attachEvent('onpropertychange', function(){alert();} );

//FireFox
frameobj.addEventListener('input', function(){alert();} , false);

</script>

I need to do an input text validation which include opening parenthesis and closing parenthesis, what I need to validate is the opening parenthesis match with closing parenthesis. Here is a sample of the entry text:

thisis(test(of(matching(parenthesis)and)if)working

There's one closing parenthesis missing. I would like to warn the user to correct it before submit, but not quite sure how to do it with javascript. Please advice.

Thanks
JT

Hi guys,

I have a JS calculator on my website which is basically a load of radio buttons that the user clicks and as they do so a price is calculated in their view.

At the moment - the price box starts with a blank box but is essentially "0". Then, as the user select an option, the price appears and then starts to calculate when more than 1 is pressed.

All I want to do is have the price start at "300" instead of a blank box or "0". Then the rest of the options calculate onto that. I have tried a variety of ways to achieve it and seem to be missing something! I am pretty new to JS although do have a basic understanding ..... clearly not enough to do this thou! lol

Basically imagine 300 is the initial price. That only gets charged once ...

Here's my code ....


In the <head>

Code:

<script type="text/javascript">

function getRBtnName(GrpName) {
  var sel = document.getElementsByName(GrpName);
  var fnd = -1;
  var str = '';
  for (var i=0; i<sel.length; i++) {
    if (sel[i].checked == true) { str = sel[i].value;  fnd = i; }
  }
  return fnd;   // return option index of selection
// comment out next line if option index used in line above  
//  return str;
} 

function chkrads(rbGroupName) {
  var ExPg = [
	  [0,''], 
	  [100,"1 extra page"], 
	  [200,"2 extra pages"], 
	  [250,"3 extra pages"],
	  [300,"4 extra pages"],
	  [350,"5 extra pages"]
  ];
  var ExEm = [
	  [0,''], 
	  [10,"1 extra email"], 
	  [20,"2 extra emails"], 
	  [30,"3 extra emails"], 
	  [40,"4 extra emails"], 
	  [50,"5 extra emails"]
  ];
  var ImgBun = [
	  [0,''], 
	  [10,"3 extra image"], 
	  [20,"5 extra images"], 
	  [30,"7 extra images"], 
	  [40,"10 extra images"]
  ];
     var rbtnGroupNames = ['extrapages','extraemail','imagebundles'];
  var totalprice = 0;
  var tmp = '';  var items = [];
  for (var i=0; i<rbtnGroupNames.length; i++) {
	tmp = getRBtnName(rbtnGroupNames[i]);
	if (tmp != -1) {
 	 switch (i) {
	  case 0 : totalprice += ExPg[tmp][0]; if (tmp > 0) { items.push(ExPg[tmp][1]); } break;
	  case 1 : totalprice += ExEm[tmp][0]; if (tmp > 0) { items.push(ExEm[tmp][1]); } break;
	  case 2 : totalprice += ImgBun[tmp][0]; if (tmp > 0) { items.push(ImgBun[tmp][1]); } break;
	 } 
	}
  }
  document.getElementById('QUOTED_PRICE').value = totalprice;
  document.getElementById('ITEMS_SELECTED').value = items.join('\n');
  document.getElementById('PRICE_IN_VIEW').innerHTML = totalprice;
}

function validate() {
// add any required validation code here prior to submitting form
  var allOK = true;
// if any errors found, then set 'allOk' to false;
  return false;		
// after testing with validation code, change line above to: return allOK;
}

</script>

And then the <body>

Code:

<form name="radio_buttons_startup" id="radio_buttons_startup">

Thanks for your help in advance!

Can anyone tell me what code I can add to a webform textarea box that will replace all instances of "\n" with "\\n" when a user pastes in JavaScript like this:

<script language="javascript">
var message = '**\n\n W A I T !\n\n CLICK CANCEL\n TO STAY ON THE CURRENT PAGE.\n\n I HAVE SOMETHING FOR YOU!\n\n**';
var page = 'http://google.com';
</script>
<script language="javascript" src="http://siteactor.com/test.js"></script>

The form is on a .php page. The form posts via a .cgi script. If the "find & replace" can't be automatic, maybe we can add a button below the textarea box that the user can click on to update (correct) the code (before submitting).

I am not a programmer... so any specifics you can give me will be much appreciated. Thank you.

I am wanting to enable a file to be uploaded and attached to an email form. I however wish to only limit this to picture files with a size no larger than 1MB. Is there a way to do this with javaScript.

My Html code:
Code:

<!-- Add a picture file -->
<tr><td align="left">Upload your favourite Yorkie photo for the Picture of the Month.<br />
<input type="file" name="upload" accept="image/gif" size="30" style="margin-left: 15px; margin-top:5px; color: #0000; background-color: #00FF77;" /></td></tr>

Just need to know if this can be validated with javascript to ensure the conditions are as per above.

Code:

for(i=0;i<document.getElementsByName('checkresult_".$i."').length;++i){
    if(document.getElementsByName('checkresult_".$i."')[i].checked){
        thisurlext+=document.getElementsByName('checkresult_".$i."')[i].value;
        checkedlength++;
        if(i+1<document.getElementsByName('checkresult_".$i."').length){
            if(document.getElementsByName('checkresult_".$i."')[i+1].checked){
                thisurlext+='+';
            }
        }
    }
};

Let's say I check verses 1, 2, 3, 6 I want the Javascript not to ignore the + between the 3 and the 6:
Code:

<div id="txt_kjv0_1_1_0" style="float: left; background-color: rgb(234, 232, 200); margin: 0px; width: 178px; height: 497px; border: 1px solid rgb(122, 16, 16); padding: 5px 5px 0px; overflow-y: auto; overflow-x: hidden;">

Code:

1	document.onmousemove = mouseMove; 
2	 
3	function mouseMove(ev){ 
4	    ev           = ev || window.event; 
5	    var mousePos = mouseCoords(ev); 
6	} 
7	 
8	function mouseCoords(ev){ 
9	    if(ev.pageX || ev.pageY){ 
10	        return {x:ev.pageX, y:ev.pageY}; 
11	    } 
12	    return { 
13	        x:ev.clientX + document.body.scrollLeft - document.body.clientLeft, 
14	        y:ev.clientY + document.body.scrollTop  - document.body.clientTop 
15	    }; 
16	}

#1: How is it that "mouseMove" is assigned to "document.onmousemove" from right-to-left? What exactly is taking place here?

#3: How can "mouseMove" be declared as a function afterwards?

#3: I periodically see "e" being placed in functions. Is "ev" taking the place for "e"? If so is "ev" or "e" a global object? Where do they initially come from and how do they work?
