hello,
i have a big javascript page that needs to be loaded and i was wondering if there is a way to put in a loading screen,
as you know, with images they take time and sometimes other objects on the page can also create the user to wait a while so my question is how do i go about creating a loading screen which will detect when all images, content and functions have been loaded and then disappear when they have finished?
do i use the windows.load event, if so is there such thing as a window.loaded event?
Thanks for all your help i have been searching for hours and still cant really get anywhere

You can use jQuery for this one - there's a document.ready event you can handle.
C# has already designed away most of the tedium of C++.

I need help with regular expression.
I have some html code into a variable that is named xmlDoc. The code includes a table and there are some things there that I want to pick out with regex.
<tr class="myGreyRow">
<td>6</td>
<td id="fn1">Prentice, Bob</td>
<td>340584305858</td>
<td>Logged out</td>
<td>
<a class="listlink" href="javascript:doEditAgent("56746")">Edit</a>,
<a class="listlink" href="javascript:doRemoveAgent("56746", "fn1")">Delete</a>,
<a class="listlink" href="javascript:doLoginLogout("4", "56746","fn1")">Log in</a>
</td>
</tr>
In this code I want to pick out:
1. The name, "Prentice, Bob"
2. The status, "Logged out"
3. The content from doLoginLogout(), "4", "56746","fn1"
How do I do this?
There are five rows similar to this in the table that I need to do this on.

Thanks, I totaly missed that there where a special Regular expression section here.

Using XPath might be a better idea to parse things out of an XML file. Just a thought. It may not apply to your application.

When I test it, the only error I get is "Expected '(' Line: 17 Char: 1. Before that I had the return statement outside of function, I moved my return statement from where I validated the comment area outside and it worked, but it seems now I have more errors than I expected. Not too sure what I am leaving out or doing wrong.

The left curly brace on the line after if is wrong. As the error message says, if should be followed by (
It always pays to read the error messages carefully, and look where they are pointing you.

I'm working on a dice-roller that's an ugly mix of PHP, JavaScript, and whatever else I need in order to make it work. The roller itself works fine, but I decided to get a little fancy with it for the sake of the person that I'm doing this for, and I tried to add logging to it, and breaking down the logs based on what "game" the user is playing. The issue is that I want to have the logs update themselves after x seconds. PHP clearly can't handle this, and my understanding is that JavaScript can't do it by itself, so I have attempted to learn enough Ajax to piece everything together. Here is what I've managed to put together:
<script type='text/javascript'>
var timer = 10;
var game_id = '$g';
var updateLogs = function()
{
var url = 'backend/timed-script.php?g=' + game_id + '&randval=' + Math.random();
var xmlhttp = new XMLHttpRequest();
xmlhttp.open('GET',url,'TRUE');
xmlhttp.send();
xmlhttp.onreadystatechange = function()
{
if (xmlhttp.readyState == 4 && xmlhttp.status == 200)
{
document.getElementById('log_box').innerhtml = xmlhttp.responstText;
}
}
}
setInterval(updateLogs, timer*1000);
</script>
I've thrown an alert() inside updateLogs to make sure that setInterval isn't failing, and that works. The issue is that the isn't populating like it should. I know that timed-script.php works (since pasting the URL in my address bar brings the page up with the appropriate data). Can someone tell me what I'm doing wrong here?
Thanks

Are you sure that is the correct url? don't you wanna take out that " backend/ "?

Thanks for getting back to me.
The PHP script is in a folder called backend that is just off the root, so the structure looks like this:
www.domain.com/broken_page.php
www.domain.com/backend/timed-script.php
If I feed the appropriate value for g to the backend script, it does display the correct data set, but it won't work with the JavaScript. I've tried pulling it out of the backend folder and into the root, but the same thing happens, or rather, doesn't happen.

I just double checked your javascript and spotted .innerhtml = xmlhttp.responstText;
try:
document.getElementById('log_box').innerHTML = xmlhttp.responseText;
Also take a look at how you create the ajax object:

Let me know if that helps,

Hi all!
I am creating one joomla site, but I am having some problems with integrating one component "Hotelgude" to my template. I created the template with Artisteer and it works, but it creates some kind of conflict and part of the component it is not showing up. Here is a link to the problem page:
www [dot] ruraltourismbg.info
As you can see the tabs bellow the main picture do not work. They should display different information. Also I can not switch between the different tabs.
As far as I understand the template creates some kind of conflict between jQuery and mootools.But my knowledge in php and scripts is limited and I can not fix it.
If anyone could help, I will be really grateful!
Thanks

Hi!
Is there someone who can help me?
|
|

Just be patient and wait. Someone will come with an answer. I never use Joomla and Artister so I can't help. But maybe someone does, so just wait patiently.
Excuse me for my improper grammar and typos.
It's because English is my primary language, not my first language.
My first languages are C# and Java.
VB, ASP, JS, PHP and SQL are my second language.
Indonesian came as my third language.
My fourth language? I'm still creating it, I'll let you know when it's done!

Hi Devs,
<div id="event">
<div class="row">
<label class="label" for="ex11">Label:</label> <br />
<input type="checkbox" id="ex11" />
<span id="status"></span> <br /> <br />
</div>
</div>
and javascript
$("#ex11")
.iButton({
change: function ($input){
$("#status").html($input.is(":checked") ? "Switched ON" : "Switched OFF");
}
})
.trigger("change");
});
Now the problem is - When check box is checked - i want to pass a variable with 1 value that will be stored in the database. How can i do that in current situation??
Do i have to pass the variable from javascript to php and then sore it in database ? If yes then what's the best way to pass variable with 1 value to php ??
Thanks

The way I would do so (if you want to do it on the fly, without the user changing pages) is to use AJAX. It's really quite simple actually, don't let AJAX scare you off if you haven't ventured into it yet.
function saveCheckBoxValue(value)
{
var xmlhttp;
if (window.XMLHttpRequest){
xmlhttp = new XMLHttpRequest();
}
else{
xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");
}
xmlhttp.onreadystatechange=function(){
if(xmlhttp.readyState == 4 && xmlhttp.status == 200){
[DO SOMETHING HERE SUCH AS THE EXAMPLE BELOW THIS]
document.getElementById('#ex11').innerHTML += "Value saved!";
}
}
xmlhttp.open("GET","[LOCATION TO PHP SCRIPT HERE]?value=" + value,true);
xmlhttp.send();
}
Then, in the HTML code for your checkbox, all you must do is this:
<input type="checkbox" id="ex11" value="" onchange="saveCheckBoxValue(this.value)" />
Not sure if this is what you were looking for, but I figured I'd give my two cents. The best part about this is that you can create multiple checkboxes, but still only use that one js function to save the values. You will most likely need to tweak this to your needs, such as the value that the checkbox must have, but it's a start at least.
Happy coding!
