JavaScript - Js Simple Function Problem?
Hello I would like to know how this is not functional. surely passing the function to another function would work so I can use the same variables without having to write it out again.

What i'm having a problem doing is changing the h3 headings so that they toggle the same way...is there a way to do this within this function without ids/classes? Code: <script type="text/javascript" src="http://code.jquery.com/jquery-latest.js"></script>
<script type="text/javascript">
$(document).ready(function() {
$('#hdg').hover(function() {
$('div[title=latin]').toggle();
$('div[title=english]').toggle();
$('#').html('<h3>English</h3>');
});
});
</script>

Why won't this code work!? Its driving me mad. How would I add up a array of numbers in a function? My numbers keep getting written as strings, instead of adding onto each other. I am a beginner. function (myNumbers) { var number = [6,9,10,13,14]; var total = 0; for(var total=0; total < number.length; total = total + 1) { total = total + number; document.write(total); } } myNumbers(); This is just an excercise. Goodafternoon! What im trying to do is get the users location (from the iPhone) which I have working and store it in a MySQL database (semi works). My problem is that to get the location, you need to use javascript. So I thought of using Ajax to post that back to the server. I have very little knowledge in Javascript, and Ajax, so this has been a bit of a struggle. Iv tried to learn how to do it with a tutorial: http://www.tizag.com/ajaxTutorial/ajax-javascript.php And this is what I got: PHP Code: <?php function is_iPhone($agent='') { if(empty($agent)) $agent = $_SERVER['HTTP_USER_AGENT']; if(!empty($agent) and preg_match("~Mozilla/[^ ]+ \((iPhone|iPod); U; CPU [^;]+ Mac OS X; [^)]+\) AppleWebKit/[^ ]+ \(KHTML, like Gecko\) Version/[^ ]+ Mobile/[^ ]+ Safari/[^ ]+~",$agent,$match)) { return "YES"; } elseif(stristr($agent,'iphone') or stristr($agent,'ipod')){ return "MAYBE"; } else { return "NO"; } } echo is_iPhone(); ?> <!DOCTYPE html PUBLIC "-//WAPFORUM//DTD XHTML Mobile 1.0//EN" "http://www.wapforum.org/DTD/xhtml-mobile10.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <title>iPhone 3.0 geolocation demo</title> <meta content="width=device-width; initial-scale=1.0; maximum-scale=1.0; user-scalable=0;" name="viewport"/> </head> <body> <script language="javascript" type="text/javascript"> <!-- //Browser Support Code function ajaxFunction(){ var ajaxRequest; // The variable that makes Ajax possible! try{ // Opera 8.0+, Firefox, Safari ajaxRequest = new XMLHttpRequest(); } catch (e){ // Internet Explorer Browsers try{ ajaxRequest = new ActiveXObject("Msxml2.XMLHTTP"); } catch (e) { try{ ajaxRequest = new ActiveXObject("Microsoft.XMLHTTP"); } catch (e){ // Something went wrong alert("Your browser broke!"); return false; } } } // Create a function that will receive data sent from the server ajaxRequest.onreadystatechange = function(){ if(ajaxRequest.readyState == 4){ document.myForm.time.value = ajaxRequest.responseText; } } ajaxRequest.open("GET", "UpdateLog.php?lat=" + Lat + "&long=" + Long + "&acc=" + Acc, true); ajaxRequest.send(null); } //--> var Lat = "" var Long = "" var Acc = "" function handler(location) { var message = document.getElementById("message"); message.innerHTML ='<img src="http://maps.google.com/maps/api/staticmap?center=' + location.coords.latitude + ',' + location.coords.longitude + '&zoom=12&size=400x400&markers=color:blue|label:S|'+ location.coords.latitude +','+ location.coords.longitude +'&sensor=true" alt="some_text"/>'; message.innerHTML+="<p>Longitude: " + location.coords.longitude + "</p>"; message.innerHTML+="<p>Latitude: " + location.coords.latitude + "</p>"; message.innerHTML+="<p>Accuracy: " + location.coords.accuracy + "</p>"; Lat = location.coords.latitude Long = location.coords.longitude Acc = location.coords.accuracy } navigator.geolocation.getCurrentPosition(handler); ajaxFunction(); </script> <div id="message">Location unknown</div> <a href="#" onclick="ajaxFunction();" >Send</a> </body> </html> Now this works if the user clicks on "Send" that I made, but I want it to do it without the user having to click send. If anyone could help me with this, or point me in a different direction that would be better then your help would be greatly appreciated. Thanks in advance for your help. EDIT: The PHP side of this works, that is something I know about lol. Hi there, I've been scouring the web and my mind for the last 24 hours trying to find a script that will work for what I need. It seems like it would be something super simple. I need visitors to my site to be able to search if we offer service in their area. i.e. Enter Zip Code: [Search Field] (Submit Button) Pop-up results or a results page with one of two responses. Yes, we offer service. No, we do not cover your area. Something similar to what this company has on their site, http://www.oilpatchfuel.com/Pages/Welcome.aspx Any help is a greatly GREATLY appreciated!! I made a 50th anniversary guestbook to add memories/etc about our organization. The people can look at the entries and then if they want to add one of there own, there's a link that should pop up a form in a new for them to add it. I have no idea why this pop is not working in Internet Explorer (both IE6 and 7). It works beautifully in Firefox. I have no idea how you can go wrong with window.open. I'm stuck. Again, only the actual pop up function doesn't work. Everything else seems to be working fine. I included all of my code though even for the tab navigation because the link to the pop up form changes based on what tab they are in (i.e. if they're looking at the past memories tab and click on the link, it takes them to the past memories form). I know it's probably TMI on the code, but I thought it might be somehow related and better safe than sorry, right? HTML Page Code: <html>

I'm not that advanced in javascript (although not a total idiot) Any help and/or suggestions would be greatly appreciated! Thank you! Code: function splook(val){
return speciesDB.queryBy(function(row){

}).itemAt(0).data.speciesDB;
}
and the speciesDB Code: {success:true,rows:[{"species_id":"1","species_idx":"1","species":"Boa Constrictor"},{"species_id":"2","species_idx":"2","species":"Ball Python"},{"species_id":"3","species_idx":"3","species":"Reticulated Python"},{"species_id":"4","species_idx":"4","species":"SriLanka Python"},{"species_id":"5","species_idx":"5","species":"Blood Python"},{"species_id":"6","species_idx":"6","species":"Burmese Python"}]}
I need to take val and match it with the data and return species. I just can't figure it out though!

I'm trying to create a function that is triggered by a <select> onchange event. It's supposed to save the newly selected value in a variable, then refer the user to a link location + variable. This is what I tried: Code: <script type="text/javascript">
function categoryRef()
{
var a = this.options[this.selectedIndex].value;
document.location = 'recommend.php?cat=' + a;
}
</script>
<select name="category" onChange="categoryRef()">
<?php
$getCategoryQuery = "SELECT category FROM categories ORDER BY category";
$ConnectQuery = $database->query($getCategoryQuery);
while($category = mysql_fetch_array($ConnectQuery)){
if($getCategory == $category['category']){
echo "<option selected='selected'>" . $category['category'] . "</option>";
}
else{
echo "<option>" . $category['category'] . "</option>";
}
}
?>
</select>
When I try this and change option nothing happens. Any pointers? Hi, I have a small script that tries to open a child window. if successful, it then closes the child window and redirects the parent window. If this process fails, there is no child window, no redirection. the script below works fine in FireFox but in Chrome, if the process fails, the redirection still happens. I'm new to JS would appreciate your help many thanks Code: <script type="text/javascript">
function openwindow(){
testWindow = window.open("popup.php","interaction");
setTimeout(function() { testWindow.close(); },1000);
setTimeout(function() { window.location = "http://www.google.com"; },1000);
}
</script>
hi there i'm a newb so be nice lol --> I want to use javascript in an array to submit content. I have some php background so using some techniques I worked this out. >> I need to select bathroom details and the script needs to be user friendly, however I have multiple bathrooms that can be selected. So based on a drop down list I need to select the bathrooms needed and then I will get more options as stated below. These options will need to be submitted so I need different varibles for each item selected I expect that you'll have a better way to do it I just want it to work my HTML script LOOKED as follows Code: <!-- BATHROOM TYPE SELECTOR HTML-->

CURRENTLY I have a drop down list from 1 to 6 when a bathroom is selected lets say 3 then it SHOULD display full - bath - shower - PER EACH BATHROOM if bath and shower is selected they disappear and full remains ticked if u tick full bath and shower disappear. included a sub cat. that changes based on the above selection this works in html but The bathroom varibles in the javascript need to be changed to suite a changing varible I based what I understand that an array will need to be added but how to i adjust the script correctly. I might work it out just have a bit of overload at the moment. Thanks in advance Hi all, I have a newbie question. I have just started working with javascript and would appreciate some guidance. I have a webpage and there are products for sale on it(this is not live it is merely being used as practice project). Beside each product is a description a price and an 'add to cart' button. My cart is simply a div with an id of 'cart' and it has a text box within it. I need the product name to be displayed within the div (this, I have working), I also need to display the product price in the text box once the button(add to cart ) for that particular product has been pressed. Also when the button for another product is pressed, I want the cost/value for that product to be added to the other value and displayed in the text box in the cart div... I apologise for rambling on but this is the best way of me explaining my needs.... Here's where i am right now.. The HTML snippet Code: <div id ="cart">
<p><img src="images/shopping-cart.png" alt ="cart"/>Your Cart</p>
<div id="sum"><!--(this is the div where the total goes)-->
<input type="text" id="total" value="0" /><p>€ Your Total <input type="reset" value = "reset" /></p>
</div>
</div>
<h2 id ="black">Blackcurrent<br /></h2>
<p>€ 12.00 <input type = "submit" value ="add to cart" onClick = "shoppingCart('Blackcurrent',12)" /></p>
And the javascript: Code: alert ("working");
function shoppingCart (itemName,itemValue)
{
/* var thePrice = Number(itemValue);

I have a simple function to display an image when called, but if I try to rewrite the function to take the image as an argument, it stops working. I've looked at other function examples on the web but can't figure out what I am missing. Can anyone help? works: Code: <html>
<script language="JavaScript">
var ImagePlusSign = '<img src="plus.jpg" name="slide" width="65" height="50"/>';
function FlashImagesThenWait()
{
document.getElementById("first").innerHTML = ImagePlusSign
}
setTimeout(FlashImagesThenWait, 1500);
</script>
<body>Hello.
<div id="first">
</div>
</body>
</html>
does NOT work : Code: <html>
<script language="JavaScript">
var ImagePlusSign = '<img src="plus.jpg" name="slide" width="65" height="50"/>';
function FlashImagesThenWait(z)
{
document.getElementById("first").innerHTML = z
}
setTimeout(FlashImagesThenWait(ImagePlusSign), 1500);
</script>
<body>Hello.
<div id="first">
</div>

Hey guys, I'm new to jquery and I'm sure this is a VERY simple problem.. Here's my code Quote: <style type="text/css"> #box { background: red; width: 300px; height: 300px; display: none; } </style> <script type="text/javascript"> $(function() { $('a').click(function() { $('#box').slideDown(4000); }); }); </script> </head> <body> <div id="box"></div> <a href="#">Click Me!</a> </body> </html> As you can see it's pretty simple, I've made the box slideIn. My problem is I want to make a separate button to slide it back out, but because I've used the "a" tag it's associating all links with the same function, how do I get around this? I'm sure it's really simple! Thanks Hi all, I'm pretty new to javascript coding and was trying to make a fading image slideshow. i have found one on dynamicdrive modified it, all looks fine. The first image shows and thats it. doesnt go through the photos :/ probably something simple but i cant work it out, any thoughts? EDIT: Code: <head>
<script language="javascript1.1">
var mygallery=new fadeSlideShow({
wrapperid: "column2",
dimensions: [250, 180],
imagearray: [
["images/img1.png"],
["images/img2.png"],
["images/img3.jpg"]
],
displaymode: {type:'auto', pause:2500, cycles: 10, wraparound:false},
persist: false,
fadeduration: 500,
descreveal: "ondemand",
togglerid: ""
})
</script>
</head>
<body>
<div id="column2"><a href="#" class="next"><img src="images/img1.png" name="slide" id="rounded-image" height="288" border="0" style="filter:blendTrans(duration=3)" alt="image-1"/></a></div>

Thanks, Storm08 Hello, Just trying to combine php variable with some javascript in a simple if ... else. This is the script code in php: Code: <script type="text/javascript">
var the_rad_val=<?php echo $N_rad_val;?>;
if (the_rad_val.value='n')
{
function removeLink();
}
else
{
function restoreLink();
}
</script>
This is how it looks in the browser (source) Code: <script type="text/javascript">
var the_rad_val=n;
if (the_rad_val.value='n')
{
function removeLink();
}
else
{
function restoreLink();
}
</script>
The 2 functions a Code: function removeLink() {
document.getElementById("mydiv").style.visibility = "hidden";
}
function restoreLink() {
document.getElementById("mydiv").style.visibility = "visible";
} // end function
Guess I did something wrong because the "mydiv" is visible when it shouldn't be Can someone help me out as I am not too good with javascript . Thank you. . I have a script that includes a JS delete function, but when I select a record and hit delete it says no record is selected. I'm sure this is a simple fix for someone in the know. Thanks in advance.
