JavaScript - Linking An External Js File?

Hello everybody,

I am currently working on displaying KML-values of ElementTags within my KML File. I already integrated the KML file as an overlay to my Google Map. But how am I able to parse the GGeoXml-object or how am I able to parse external ("http://www.myexample.org/polygons.kml" instead of just "polygons.kml") XML-files?

At the moment my code for loading the geoxml file looks like this:

Code:

function initialize(kmlFile) {
      if (GBrowserIsCompatible()) {
        var map = new GMap2(document.getElementById("map_canvas"));
        map.setUIToDefault();
        map.setCenter(new GLatLng(53.763325,-2.579041), 9);
             // ==== Create a KML Overlay ====
      if(!(kmlFile==null)){
          //check if it doesnt start with "http://"
        if(!(kmlFile.startsWith("http://"))){
        kmlFile = "http://" + kmlFile;
        $('kmllink').value = kmlFile;
        }
        var kml = new GGeoXml(kmlFile);
        //add Overlay to the googlemaps window
        map.addOverlay(kml);
        //$('subject').value = "SUBJECT";
        //$('content').value = "CONTENT";
        kml.gotoDefaultViewport(map);
        // Store center and zoom as properties of the object kml
        var centerKML= kml.getDefaultCenter();
        var zoomKML = map.getZoom();
        map.panTo(centerKML);
        map.setZoom(zoomKML);
        }
        
      }
      
}

And for parsing local XML-files this code works already:
Code:

function loadXML()
{
if (window.XMLHttpRequest)
  {
  xhttp=new XMLHttpRequest();
  }
else // Internet Explorer 5/6
  {
  xhttp=new ActiveXObject("Microsoft.XMLHTTP");
  }
    xhttp.open("GET","test.kml",false);
    xhttp.send("");
    //xmlDoc=xhttp.responseXML;
    xmlDoc = xhttp.responseXML;
    var placemark=xmlDoc.getElementsByTagName("Placemark");
    alert(placemark[0].getElementsByTagName("name")[0].childNodes[0].nodeValue);
    ajaxLoader("http://www.zki.dlr.de/mod/ext/fireModis/yesterday_en.kml","Placemark");
}

My question: Is there any way to integrate parsing external xml files in any of these two functions?

Best regards,
TsEMaNN

Code:

	
	<!-- Add-in device.js files are placed here -->
	<div id="deviceScript"></div>

What I have been doing is clearing this out when I select a new (add-in) device and append a script tag with its .src file.

I have some vague idea that unhooking an external js file might remove its code from memory. If not is there a way to do so?

Functions in different script files have the same name - for example, I use start() to set up each device. It seems that the latest device start() overwrites the one in memory - but I am not sure if overwrite means delete last one or whether there is some horrendous build up of dross going on.

Any clarification appreciated.

I have an issue with my javascript files loading (i.e. checking the source code of the page after having loaded yields working links to my external files and the JQuery loading for sure after running some test), but calling a function from my javascript file works in no way shape or form. For example, one test I was running was:
From my .js file
Code:

$("p").click( function() { $(this).hide(); } )

This will work on a standalone page when I test it (not loading from external .js file), but not in the page I need to get my scripts running on.

I have this file:

IPToned.js
Code:

// ==UserScript==
// @name          IPToned
// @namespace     http://users9.jabry.com/chatleague
// @description   IPTorrents Filter Enhancements
// ==/UserScript==

 
alert("hello world");

I drag and drop it into Firefox (Ubuntu) and it opens it as if it were a txt file. I want it to make the alert so I can get to coding. Any suggestions?

Hi guys. I've made a html file with three lists to populate different pages of my site. Then i've called the html with SSI. let me show the code

can someone tell me how can I do this please. Maybe with javascript?

thanks in advance

Hi,

I need some help with a bit of a challenge.

I need to allow users to spesify a file stored on their hard drive, read the file and populate a table and eventually a database.

I can probably upload the file using <input type='file'> but what then? How do I access the file after this, or is there a better way? Using XMLHTTP gives 'access denied.....' I can not use PHP as the site does not support PHP. For those who know the environment - it's a QuickBase application I need to upload to.......

Thanks
Nic

I'm trying to execute an php file (which is present on an other host) by javascript. I've got three files for this:

The javascript that calls the main program (launch.htm):
Quote:

<html>
<script type="text/javascript">
document.write(unescape("%3Cscript src='http://www.mysite.com/reservetest.js' type='text/javascript'%3E%3C/script%3E"));
</script>
</html>


The main program: (reservetest.js)

Quote:
function goer() {
var url = 'test.php';
var pars="x=4&y=3";
makeHttpRequest(url+"?"+pars, thanks);
}

function thanks(text) {

document.write(text);
//$("divname").innerHTML=text;

}

function $() {
if (arguments.length == 1) return get$(arguments[0]);
var elements = [];
$c(arguments).each(function(el){
elements.push(get$(el));
});
return elements;

function get$(el){
if (typeof el == 'string') el = document.getElementById(el);
return el;
}
};

function makeHttpRequest(url, callback_function, return_xml)
{
var http_request, response, i;

var activex_ids = [
'MSXML2.XMLHTTP.3.0',
'MSXML2.XMLHTTP',
'Microsoft.XMLHTTP'
];

if (window.XMLHttpRequest) { // Mozilla, Safari, IE7+...
http_request = new XMLHttpRequest();
if (http_request.overrideMimeType) {
http_request.overrideMimeType('text/xml');
}
} else if (window.ActiveXObject) { // IE6 and older
for (i = 0; i < activex_ids.length; i++) {
try {
http_request = new ActiveXObject(activex_ids[i]);
} catch (e) {}
}
}

if (!http_request) {
alert('Unfortunately your browser doesnt support this feature.');
return false;
}

http_request.onreadystatechange = function() {
if (http_request.readyState !== 4) {
// not ready yet
return;
}
if (http_request.status !== 200) {
// ready, but not OK
alert('There was a problem with the request.(Code: ' + http_request.status + ')');
return;
}
if (return_xml) {
response = http_request.responseXML;
} else {
response = http_request.responseText;
}
// invoke the callback
callback_function(response);
};

http_request.open('GET', url, true);
http_request.send(null);
}

goer();

And finally the test file (test.php):

Quote:
<html><body>just a test</body></html>
It works fine when I use all three files on the same host. However when I use launch.htm on an other host (which is the idea behind it) it gives me 'There was a problem with the request (code 0)'. When I change the url variable within reservetest.js to a relative/absolute path it gives me a 'access denied' on http_request.open line.

Main idea is to show the user (who puts the code from launch.htm) on his/her website the contents of my test.php file (which retrieves mysql data). I think it's a security issue with the http_request.open line. Is there a way to work around this? Or am I missing something here? I don't want to use an iframe to retrieve information from my other host.

Hello Guys,

I have a question here..

I have a scroller on my pages that basically reads a text file and displays.. The problem that I am having is it doesn't update until I reload the page(even though the .txt file updates about every 3 minutes).. I would like it to update when the file has been changed..

Here is my page.

PHP Code:
<link rel="stylesheet" href="../../css/li-scroller.css"  type="text/css">
<script src="../../js/jquery.li-scroller.1.0.js" type="text/javascript"></script>
 <script type="text/javascript" src="../../jquery-1.6.1.min.js"></script>
   <script type="text/javascript">
       $(function(){
    $("ul#ticker01").liScroll();
    }); 
</script>

<?php 
 $file = file_get_contents ('playingnow.txt'); 
 
 ?> 
<div class="scrollpos">
    <ul id="ticker01">
    <li><a href="#"><?php Echo $file;?></a></li>
    
    <!-- eccetera -->
    </ul> 

</div>

What can I add to make it go out and reload just the div not the entire page?

Please advise..

Hi

I'm trying to call a external .js file that contains a function from a webpage, but haven't been able to discover how to reference the function.

First, the function:
Code:

function biggestOfTwo(valueOne, valueTwo)
{
	var big;
	
	if(valueOne > valueTwo)
	{
		big = valueOne;
	}
	else
	{
		big = valueTwo;
	}
	
	return big;
}

... and the xhtml calling it...

Code:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
        "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">

<head>
	<title>An XHTML 1.0 Strict standard template</title>
	<meta http-equiv="content-type" 
		content="text/html;charset=utf-8" />
		
<script src="compare.js" type="text/javascript" />
		
</head>

<body>

<script type = "text/javascript">
	var dataInput1;
	var dataInput2;
	dataInput1 = prompt("Enter the first number to be compared");
	dataInput2 = prompt("Enter the second number to be compared");

	alert("The biggest value is " + biggestOfTwo(dataInput1, dataInput2));
</script>
</body>
</html>

According to the book Beginning JavaScript 4th Edn, this should work - why isn't it?

Hello all, and thanks in advance for the help.

I want to update a div using innerHTML and take the data from an external HTM file residing on my server. The purpose is to have a series of links in the div content_left that when clicked dynamically change the div content_right. That will allow me to create individual pages for the dynamic content rather than including it all on the original page.

Any help is appreciated.

Hi,
I read several examples, tried them all out - and nothing works! Driving me crazy - completely insane! Maybe you guys can help

My problem is simple:

file B.html includes this line:
Code:

<script type="text/javascript" src="B.js" defer="defer"></script>

file B.js is a regular JS file, yet I need to insert a PHP function in it (yeah - I know it will operate server-side before the page reaches the browser). I did something like:
Code:

(some js code)
var user_id = <?php $a=100; $b=200; $c=$a+$b; echo($c);?>;
alert("Your user ID is:" + user_id);
(some more js code)

(What I expect is the browser to see the line as: var user_id = 300; )

Doesn't work. Renaming B.js to B.php did nothing.
What am I doing wrong?

Thanks!

Hello!

How can you make a bookmarklet access an external file? (C:/testFile).
The external file code is simply: Code:

alert("hello");

I have tried the following code to call my external file:

Code:

javascript:(function(){document.body.appendChild(document.createElement('script')).src='file::/C:/testFile';})();

...but it's not working. Please help.

I am using Windows 7 and IE8.

Any solutions appreciated.

Thanks in advance.

Hi I have 2 external javascript files added in the head section of a html file but neither will work. However, if i place the javascript code in the html file it work. I'm lost and need help. Could it be the onload function Code:

<body onload="showCookies(); startBanner();">

I have HTML page which use js function and worked fine b4 I pull out the javascripts function from that page.
Then later, I created .js file for the js functions and test again, the function doesn't work anymore.

In .js file,
<script type="text/javascript">
var upload_number = 2;
function addFileInput() {
var d = document.createElement("div");
var file = document.createElement("input");
file.setAttribute("type", "file");
//file.setAttribute("name", "attachment"+upload_number);
file.setAttribute("name", "ufile[]");
file.setAttribute("size", "40");
d.appendChild(file);
document.getElementById("moreUploads").appendChild(d);
upload_number++;
}
</script>
*************
Then in html page, I put

<script language="javascript" src="jsfile/test.js"></script>

in the <head> tag and call the function in <body> tag,

<div id="moreUploads"></div>
<div id="moreUploadsLink" style="display:none;">
<a href="javascript:addFileInput();">Upload another File</a>
</div>
********************

When I click on the Upload another file link, nothing appear.
It worked b4 I create separate js file.
Pls help me solving this problem and gimme suggestions.

Thanks in advance!
