noUiSlider is 'undefined'

Recommended Posts

Hello, i tried to style up my script.

i integrated a noUiSlider but it doesn't work. i looked for solving in the documentation, YouTube and google, without success. Can someone help me to make it work?

The JavaScript Code can be found at the bottom of the script tag. Thanks!

The first thing you need to do is delete that sleep function before you accidentally use it.  Javascript has several ways to delay execution without making the browser use as much CPU as possible looping over and over.

All of your script tags are after the body tag.  I'm not sure if the browser is going to ignore that or not.  Put them in the body.  You're also including jQuery three times, the last one will overwrite the others.  Only include the one version you need.

The reason for the error message is because you're trying to run the noUiSlider function at the end of the head section, but you don't include those files until after the body (if they get included at all).  You can't run that function before the files that define it have been included.  Either use a load handler to run your initialization stuff or move that code after all of the files get included.

Thanks someguy for your explanations. The first two aspects i understand an i can handle.

The third aspect is a little bit "foggy" for me. I understand that i try to start the function in the head. Where else can i run it. I tried different "positions" like also head area, after the the </html> in the body... no useful result. finally i see the hole code as text now.

It would be really nice, if you can show me the right line an structure. With best regards...

The body ends at </body>, nothing except the closing </html> tag should be after that.  If you put code in the head that you want to run when the page is finished loading, use a document load or ready event listener to run that code when the page finishes loading.  Or, put it at the end of the body (but still inside the body) after you include all of the script files.

Yeah, there is no longer an error in the console logged. The JS-Files are included. But now i don't see a slider :-/ . On the left side of "Min-Wert" should it visible.

here is the example. In developmentmode on the browser i see the needed div. But there is no content unfortunatly.

yes, i made buttons and it's also okay. so i changed some points in the code and my kids can use it now ;-).

I have another question. Trying to control how many tasks and which skill they train i added some more variables an print them in a table "solved tasks" for each level.

This level i want to send by xmlhttp.request after hitting the yellow button. if i log the transaction in console i see the values of the variables: niveau1 and niveau2. I use GET to transfer. Unfortunately i loose the information in this process. The responstext is without the php echo value :-/

Thanks so much for being so patient with me ;-)

 

the JS-Code

function sendData() {
	console.log('niv1: '+niveau1+' niv2: '+niveau2); // I SEE THE VALUES IN CONSOLE
	var xmlhttp = new XMLHttpRequest();
	xmlhttp.onreadystatechange = function() {
		if (this.readyState == 4) {
		console.log(xmlhttp);
		}
		if (this.readyState == 4 && this.status == 200) {
		document.getElementById("returnresponse").innerHTML = this.responseText; // responseText is empty
		}
	};
	xmlhttp.open("GET", "rechnensave.php?", true);
	xmlhttp.send('niv1='+niveau1+'&niv2='+niveau2);
}

PHP(rechnensave.php):

<?php

header('Content-Type: text/html; charset=utf-8'); 
header('Cache-Control: must-revalidate, pre-check=0, no-store, no-cache, max-age=0, post-check=0'); // for IE

$niv1	= $_GET['niv1'];
$niv2	= $_GET['niv2'];
echo "Test: ".$niv1." / ".$niv2; // responseText shows "Test / "

?>

i got it working...

ich changed the xml open part as following:

xmlhttp.open("GET", 'rechnensave.php?niv1='+niveau1+'&niv2='+niveau2, true); 
xmlhttp.send();

THANKS for your support...

Thread can be closed, but the slider doesn't still work.
