JavaScript - Connecting Javascript To Mysql...
From what I know, it's not possible. I am working on a site where a calculation has to be performed. The calculation is (exercise cal burned X current weight X time spent). The problem is that this information is stored in a database within phpmyadmin. So, my question is: is there a workaround for that? if so, what is it? if not, what is the best way for me to extract that information in the database to setup the calculation? I was thinking of using an array, but there are 30+ exercises listed, each with different values for the calories burned. What should I do?

Hi all, I'm trying to make a digital order sheet for my brother. I made him a database in phpmyadmin, that has 2 tables, called Dishes and Cables. 2 different PHP sites call those tables, and pull the information. I then have an HTML page set to display that information. Here's what it looks like. <html> <head> <script type="text/javascript" > var data = null; var data2 = null; function GETSTUFF(stuff) { function buildList() { function showQuantity() { var supplier = document.getElementById('materials').options[document.getElementById('materials').selectedIndex].value; var amount = 0; for (var i=0;i<data.length;i++) { if (data[i]['Supplier'] == supplier) { amount = (data[i]['Quantity']); } } document.getElementById('quantity').innerHTML = 'Quantity : '+amount; var type = document.getElementById('materials').options[document.getElementById('materials').selectedIndex].value; var amount2 = 0; for (var i2=0;i2<data2.length;i2++) { if (data2[i2]['Type'] == type) { amount2 = (data2[i2]['Quantity (Boxes)']); } } document.getElementById('quantity').innerHTML = 'Quantity (Boxes) : '+amount2; } </script> </head> <body onload="setTimeout('buildList()' ,100)"/> <center> <img src="images.jpg" width=125px height=125px/> <br> <font size="8" color="grey" face="purisa">Home </font> <font size="8" color="red" face="purisa"> Communications</font> <br> <font size="5" color="grey" face="purisa">Order </font> <font size="5" color="red" face="purisa"> Sheet</font> <br> <table border="3" width="100%"> <tr> <th>Material:</th> <th>Quantity in stock:</th> <th>Quantity needed:</th> </tr> <tr> <td> <select id="materials" onchange = "showQuantity()"> <option disabled>Select</option> </select> </td> <td id="quantity"/> <td> <form> <input type = "quantityNeeded" /> </form> </td> </tr> </table> <br> <input type = "button" value="Submit"/> </center> </body> </html> My idea is that if the stuff from Dishes is selected, then display the quantity for that, and if the stuff from Cables is selected, display the quantity for that. This obviously involves an if statement, but nothing I can think of makes it work.

Hi, I have the below code (in a smarty .tpl file), but would like to automate it with data from MySQL DB and PHP So for example if I was to add another gift_id radio box etc.. in MySQL it would add on to the end extending the if statement to make sure a radio box has been picked. if ((form.gift_id[0].checked == false) && (form.gift_id[1].checked == false) && (form.gift_id[2].checked == false)) { ErrorCount++; But the problem is I am not sure how to do this, any ideas?

I am building webpage that displays a clock , a ticker box and a countdown(alarm clock). I have found many previously coded alarm clocks/countdown timers but they dont do what i need. Then what do you need you might be asking yourself?! - I need a countdown timer with background in MySQL database(there will be multiple events in that database) and then checks which is the next one( Alarms will be in HH:MM format so they can be activated every day), after the check it displays a countdown(logical eh?) until that event - when it reaches that event it should redirect to some other site(which will return user to the same site after 15 min pause) and then All over again, check which is next, countdown , redirect , AGAIN This website is designed not to be clicked or anything - it should work by itself. Are YOU able to help me? (Just a fair warning - Im a newb in javascript so dont be too harsh on me) Hello. I have a problem here I have this menu: Code: <script language="JavaScript">

And I have a database with 3 fields: id, name and contents. These are the pages. Basically I want to do a select on the mysql database using PHP and populate the menu from the database. Can you tell me how to do this? Thanks Ok so Im going to break down what Im trying to do and hopefully someone can point me to a possible solution without getting all technical. I have 2 div tags. the first is a content container more or less. the second is a container for a php built calender (using html tables). Basically when the page loads the php builds the calenders html table code. each td element has an onclick event handler. The goal is to have the javascript handler execute when any non empty cell is clicked (non empty being that it has a date associated with it and is not a blank space filler). This is the easy part. The hard part is that each calendar day potentially has certain information associated with it stored in a mysql database. Im wanting input fields within the first container div to autopopulate with the information from the database (if any) for whatever day is clicked. Ive search around and heard things like javascript cant do mysql queries directly, and heard mention of ajax. So im stumped as to how to accomplish this. whether i need an external php script for the queries (perhaps inside a php function that can return data to the javascript that calls it?), but if that is plausable would it cause page loads or the like to the user? i really dont want to have to learn ajax for this one page, just seems excessive, but i do need a way to make the content in the first div populate with the respective database data for the selected day on the calendar. any thoughts, comments, or solutions that dont involve yet another web language would be greatly appreciated. thanks
Hello! I am trying to find a script that allows you to open multiple browser tabs and then close each of those tabs, either one by one or all at once. Does anyone know how to do this please? Thanks so much for your help. I want to have another go at Javascript. I have several books on the subject but I find that my eyesight is a major problem. Therefore I want to try an on-line solution, preferably free. I have Googled, but there are so many that I am almost dizzy with the choices. Perhaps someone could recommend one. Not too fussy visually. My knowledge is VERY basic. Frank Does anyone know how to make URL links that use Javascript still work when users have Javascript disabled on their browser? The only reason I'm using JS on a URL is because my link opens a PDF file, and I'm forcing it not to cache so users have the latest version. I tried the <script><noscript> tags, but I'm not sure if I'm using it correctly, as my URL completely disappears. Below is my HTML/Javascript code: <p class="download"> <script type="text/javascript">document.write("<span style=\"text-decoration: underline;\"><a href=\"javascript:void(0);\" onclick=\"window.open( 'http://www.webchild.com.au/mediakit/Direct_Media_Kit_Web.pdf?nocache='+ Math.floor( Math.random()*11 ) );\" >The Child Magazines Media Kit</a></span> (PDF 1 MB) ");</script> <noscript><span style="text-decoration: underline;"><a href="http://www.webchild.com.au/mediakit/Direct_Media_Kit_Web.pdf" >The Child Magazines Media Kit</a></span> (PDF 1 MB)</noscript> </p> Thanks for any help, Michael Hi, I have the following code snippet: test.html ====== <script language="javascript" type="text/javascript"> var testVariable = "test"; </script> <script language="javascript" type="text/javascript" src="test.js"> </script> test.js ===== var testVariable = window.top.testVariable; In firefox, I'm able to access testvariable defined within test.html in test.js. But in chrome, test.js couldnot get the window.top.testVariable field defined in test.html. Can any one please let me know how i can make it work in chrome?. Am i missing something here?. Hi Guys, I am new at JavaScript and start to do some tutorials.What I am trying to do here is prompting user to input a name and if the name was valid the page(document) will display with all objects like the button.But if user enter a wrong name then the button will be disabled! I create the following code but it did not work <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>New Web Project</title> <script language="JavaScript" type=""> function changeColor(){ document.bgColor = "Gray"; } </script> </head> <body> <script language="JavaScript" type="text/javascript"> var person = ""; person = prompt('What is Your Name:'); if (person == "Foo") { document.write("<h1 />Welcome " + person); document.bgColor = "Yellow"; } else { document.write("<h1 />Access Denied!!!!"); document.bgColor = "Red"; document.getElementById("gree").disabled = true; } </script> <div> <p/><input id="gree" type="button" value="Gray " onClick="changeColor();"> </div> </body> </html> as you can see I used the: document.getElementById("gree").disabled = true; but it did not work , could you please give an idea how I can solve this problem? Thanks Hi Guys I am trying to modify the functionality of my page. I want to be able to activate this piece of code using another javascript function. This is the code I want to activate: Code: <script type="text/javascript"><!--
$('#button-cart').bind('click', function() {
$.ajax({
url: 'index.php?route=checkout/cart/update',
type: 'post',
data: $('.product-info input[type=\'text\'], .product-info input[type=\'hidden\'], .product-info input[type=\'radio\']:checked, .product-info input[type=\'checkbox\']:checked, .product-info select, .product-info textarea, .date_data input[type=\'text\']'),
dataType: 'json',
success: function(json) {
$('.success, .warning, .attention, information, .error').remove();
if (json['error']) {
if (json['error']['warning']) {
$('#notification').html('<div class="warning" style="display: none;">' + json['error']['warning'] + '<img src="catalog/view/theme/default/image/close.png" alt="" class="close" /></div>');
$('.warning').fadeIn('slow');
}
for (i in json['error']) {
$('#option-' + i).after('<span class="error">' + json['error'][i] + '</span>');
}
}
if (json['success']) {
$('#notification').html('<div class="success" style="display: none;">' + json['success'] + '<img src="catalog/view/theme/default/image/close.png" alt="" class="close" /></div>');
$('.success').fadeIn('slow');
$('#cart_total').html(json['total']);
$('html, body').animate({ scrollTop: 0 }, 'slow');
}
}
});
});
//--></script>
And this is how I want the format of the function to be: function testsession() { if there is a session called 'hiredate' { activate the script above } else { var el = document.getElementById("product_data"); } } I just dont know how to write this in javascript Could you help me if possible please I got an index.php Code:
<html>
<form action="bacakomik.php" method='post'>
<select name="kodekomik">
<option value='../komik1/|23'>Judul Komik1</option>
<option value="../komik2/|20">Judul Komik2</option>
<option value="../komik3/|10">Juduk Komik3</option>
<option value="../komik4/|20">Judul Komik4</option>
</select>
<input type="submit" />
</form>
<?php
echo ('<select>');
echo ('<option value= "'.$i.'">'.'Page '.$i.'</option>');
echo ('</select>');
?>
</html>
As you can see, each of the option brings specific value "../komik1/|23" komik1 is a directory | is a delimiter 23 is the pages in one chapter and can be considered also as how many images are there on a specific directory This is my bacakomik.php Code: <?php
$dirkomik = $_POST['kodekomik'];
$exploded = explode("|", $dirkomik);
echo ($exploded[0]); //picture directory
echo ("<br>");
echo ($exploded[1]); //total page in the comic
$pagecount = (int)$exploded[1];
//Take last posted value, process it right away
echo ('<FORM name="guideform"> ');
echo ('<select name="guidelinks">');
$i=1;
do {
echo ('<option value= "'.$i.'">'.'Page '.$i.'</option>');
$i= $i+1;
}while($i <= $pagecount); //Printing option and select
echo ("</select>");
?>
<input type="button" name="go" value="Go!" onClick="document.getElementById('im').src=document.guideform.guidelinks.options[document.guideform.guidelinks.selectedIndex].value+'.png';"> </FORM>
<img src="img0.jpg" id="im">
With the current code on bacakomik.php, I only can change the img src of id "im" in the same directory only. What I want is that the Javascript could "add" the "$exploded[0]" variable so that the picture can be loaded from different directory. Anyone can do this? I believe that the fix should be somewhere on input tag inside OnClick, or do you know where? Anyway, I found this on the net http://p2p.wrox.com/php-faqs/11606-q...avascript.html Please help me to those who can...
