Is there a way to instantly trigger or execute the downloaded file using html only?
Here is the simple script that I am using and this call will just simply download my app but my aim is not just simply download it but what I need is to execute directly on what I've downloaded on this link
href="http://localhost:8088/main/system/launch/client/MyApp.jnlp"
Appreciate any suggestions or commentsm TIA.
You probably want to read this: https://docs.oracle.com/javase/tutorial/deployment/webstart/deploying.html. The file you're trying to run is kind of like a Java applet, and will require Java to be installed on the client as well as get permission, etc. to open.
That page goes into detail about what html markup is required, particularly this part
Create the HTML page from which your application will be launched. Invoke Deployment Toolkit functions to deploy the Java Web Start application.
In the example, the Dynamic Tree Demo application is deployed in JavaWebStartAppPage.html.
<body>
<!-- ... -->
<script src=
"https://www.java.com/js/deployJava.js"></script>
<script>
// using JavaScript to get location of JNLP
// file relative to HTML page
var dir = location.href.substring(0,
location.href.lastIndexOf('/')+1);
var url = dir + "dynamictree_webstart.jnlp";
deployJava.createWebStartLaunchButton(url, '1.7.0');
</script>
<!-- ... -->
</body>
My guess is you could simplify it by doing something like this:
<body>
<!-- ... -->
<script src="https://www.java.com/js/deployJava.js"></script>
<script>
deployJava.createWebStartLaunchButton(
"http://localhost:8088/main/system/launch/client/MyApp.jnlp",
"1.7.0"
);
</script>
<!-- ... -->
</body>
It seems that when you run the above code, something like this appears below it:
<img src="//java.com/js/webstart.png" border="0">
So you might try just running a modified version of the JavaScript inside of that href. In your case, probably:
const url = "http://localhost:8088/main/system/launch/client/MyApp.jnlp";
if (!deployJava.isWebStartInstalled("1.7.0")) {
if (deployJava.installLatestJRE()) {
deployJava.launch(url);
}
} else {
deployJava.launch(url);
}

Very basic question about html.
Because the <body> is too long, I want to divide the file into multiple files. It is not about using iframe etc, but just want to include multiple text files to create <body> of the html file.
Thank you!
You can do it using jQuery:
<head>
<script src="jquery.js"></script>
<script>
$(function(){
$("#ContentToInclude").load("b.txt or b.html");
});
</script>
</head>
And load it in HTML:
<body>
<div id="ContentToInclude"></div>
</body>
Just change the extension to .php instead of .html. Then you can just put, for example, your whole head inside the file head.php( or head.inc).
The whole thing would look something like this then:
<!DOCTYPE html>
<?php
include 'head.php';
?>
<body>
<!-- stuff in here -->
</body>
<html>
You can obviously split your body up into seperate pieces like this:
<body>
<?php
include 'firstPart.php';
?>
<!-- some other stuff -->
</body>
You can easily break your code in multiple files, Then create one file with .php extension and include them all!
With only HTML it would not be possible you need to add some JavaScript to be able to do so.
Using a data attribute with the Fetch API and some async functions you could do it as follow:
HTML file:
<div data-src="./PATH/filename.html"></div>
This element will receive as HTML content the content of the file specified in its data-src attribute.
Now the JavaScript:
async function getFileContentAsText(file) {
const response = await fetch(file);
const fileContent = await response.text();
return fileContent;
}
async function insertContentsFromFiles() {
const tbl = document.querySelectorAll('[data-src]'); // get elements with the data attribute "data-src"
for (var i=0; i < tbl.length; i++) // loop over the elements contained in tbl
tbl[i].innerHTML = await getFileContentAsText(tbl[i].dataset.src);
}
// dont forget to call the function to insert the files content into the elements
insertContentsFromFiles();
When the insertContentsFromFiles() method will be called it will first retrieve all the elements that have the data attribute data-src then we loop over these elements using their data-src value with the getFileContentAsText() method to affect their innerHTML property as the content of the file specified in the data attribute.
As we are using querySelectorAll() to get the elements with the data-src attribute the above JavaScript code will work for an unlimited amount of elements as long as they have that data attribute.
Note: In its current state the above JavaScript code is not optimized for loading a big amount of files as it process the files to be loaded one by one. If you are interested in solving this issue you may want to use promise.all() and update the insertContentsFromFiles() method to parallelize the files loading by taking advantage of the asynchronous operations.
Warning: If you plan to use elements that are in the loaded files from JavaScript you will have to retrieve them after they have been loaded into the page otherwise they will have an undefined value. To do so you can dispatch an event when a file has been loaded so you can attach specific functionnalities to the page based on the triggered events.
How can I read the contents of a file using
<link href='path/to/file'/>
I understand that if one adds the attribute type="text/css" then they can be read using document.styleSheets but I have a hard time figuring out how to get the content of that element though.
I understand that lesscss.js lib uses the without an ajax get call.
From: http://lesscss.org/#using-less
<link rel="stylesheet/less" type="text/css" href="styles.less" />
<script src="less.js" type="text/javascript"></script>
I need to include some templates into the page, and the sooner they are loaded the better, ( vs doing it after jquery and js has loaded)
Thanks!
I understand what you mean with before jquery. But what do you mean with "before js".
When you load less.js (which does NOT depend on jQuery) the browser runs less.js before jquery has been initialized. Notice that less.js requires JavaScript.
You can read the content of such a file leveraging a XMLHttpRequest. A basis example which shows you how to do this can be found at: How to show the compiled css from a .less file in the browser?
Regarding less.js, you can find the source of that file at: https://github.com/less/less.js/blob/master/dist/less-1.7.4.js
I understand that if one adds the attribute type="text/css" then they can be read using document.styleSheets but I have a hard time figuring out how to get the content of that element though.
Globally less.js uses two steps to do that:
first it will built a list of paths as follows:
//
// Get all <link> tags with the 'rel' attribute set to "stylesheet/less"
//
var links = document.getElementsByTagName('link');
less.sheets = [];
for (var i = 0; i < links.length; i++) {
if (links[i].rel === 'stylesheet/less' || (links[i].rel.match(/stylesheet/) &&
(links[i].type.match(typePattern)))) {
less.sheets.push(links[i]);
}
}
Then reads the content of these files by using a XMLHttpRequest too. See the doXHR function at line 7720 of less-1.7.4.js.
I can't figure out why for example I try to reproduce something basic like this example https://google-developers.appspot.com/earth/documentation/samples/fetchkml_example on my own, I can't get it to work. I'm using my key that I have been using for my Google Maps API, so I think that part should be fine, but when it comes to KML I can't seem to get it to work regardless of whether it is fetched or parsed. I have put my KML file here https://sites.google.com/site/shahinkmlexamples/experiment/kml_example.kml , and my code is below with my own key number not shown
<html>
<head>
<title>fetchkml_dom_example.html</title>
<script src="//www.google.com/jsapi?key=MYKEY#"></script>
<script type="text/javascript">
var ge;
google.load("earth", "1");
function init() {
google.earth.createInstance('map3d', initCB, failureCB);
}
function initCB(instance) {
ge = instance;
ge.getWindow().setVisibility(true);
var href = 'https://sites.google.com/' + 'site/shahinkmlexamples/experiment/kml_example.kml';
google.earth.fetchKml(ge, href, function(kmlObject) {
if (kmlObject)
ge.getFeatures().appendChild(kmlObject);
if (kmlObject.getAbstractView() !== null)
ge.getView().setAbstractView(kmlObject.getAbstractView());
});
}
function failureCB(errorCode) {
}
google.setOnLoadCallback(init);
</script>
</head>
<body>
<div id="map3d" style="border: 1px solid silver; height: 400px; width: 600px;"></div>
</body>
</html>
so I know the solution has got to be simple, but I just can't figure it out.
Thanks
When you're loading it from a local file (such as using notepad++ and loading that file in Chrome) you need to add a protocol to the script tag:
<script src="//www.google.com/jsapi?key=MYKEY#"></script>
Becomes:
<script src="https://www.google.com/jsapi?key=MYKEY#"></script>
Without that change, your page is looking for the file in your local filesystem.
It's left out in the samples so that your browser will load the HTTPS version if your page is HTTPS, and the HTTP version if your page is HTTP. This prevents security warnings in the browser.
I'm not sure what your problem is. I put your code into an online editor - http://www.onlinehtmleditor.net/
a simple copy and paste and it worked fine.
Also, regarding the API key. For Google Earth you no longer need one. Simply use the generic javascript call below
Is there any way to write script in css and call or execute it whenever required ?
I need a <script> tag to be executed .
i need something like this..
css code
#execute{
<script> ..some script.. </script>
}
so whenever i use
<html>
.
.
.
.<div id="execute" />
.
.
.
.
</html>
so if i change the script changes will be reflected everywhere.
Is it possible?
EDIT:
Is it possible to keep my <script></script> tags inside some js file and i will host it. and then i will call some function() from my HTML so that the script will be executed everywhere i need it.
Can someone show me any example, tutorial how i can do it.
I don't have much information about the Js file and how the function should be called.
Thank you all
Does it have to be in CSS? jQuery is a great, simple way to do what you're asking. You put all your style information in the CSS (what it's intended for) and keep your javascript in the html or a .js file. Take a look at http://jquery.com. The code would look something like this
$(function() {
$('#execute')
.someCoolFunction()
.anotherCoolFunction();
});
You use $(function() { /* code */ }); to run the code when your document is ready, and you use $('#execute') to grab the element with the execute tag. You can then do a lot of cool javascript really easily with that jQuery element.
No, you cannot mix CSS and Javascript this way. Why would you want to?
If you simply want a common JavaScript include, do it like this:
<script type="text/javascript" src="yourscript.js"></script>
You can't do this in standard CSS.
There is a way in which you can run code from within the CSS context, using a technology called 'Behaviours', referencing an HTC file (which is basically Javascript) in the stylesheet.
However, this technology is non-standard, and only exists in IE. It is therefore only really used to write hacks to make IE support features that it doesn't have which are in other browsers. An example of this in use is CSS3Pie.
If you're working on a site which will never be used in any browser other than IE, and you're happy to use a non-standard technology, then you may consider this to be the exact answer to your question. However I would strongly recommend you don't do this.
More realistically, you should be using a Javascript library such as JQuery, as the functionality you describe is pretty much standard fare for JQuery.
With JQuery, you would write code like this (in a normal script block, not in the CSS!):
$('.execute').each(function() {
/* your code here; it would be run for each element on the page with the class of 'execute' */
}
As you can see, it uses a CSS-style selector syntax to select the elements to work with.
(also NB: I've used execute as a classname here, not as an ID, because you imply that you want more than one of them -- note that you should never use the same ID more than once in any HTML page; it is invalid. If you need the same thing several times, use a class.
JQuery has functionality to watch for changes to elements, respond to events such as clicks or mouse over, and much more. Other similar libraries such as Prototype, MooTools and Dojo would also be able to do a similar job.
Hope that helps.
[EDIT]
Given the edit to your question, can you not just place the advertisment <script> tag inside the <div> on the page where you want it?
So with JQuery, you could write something like this to run your ad in each place you want it:
HTML:
....
<div class='execute'></div>
....
<div class='execute'></div>
....
Javascript code (remember to also include the JQuery library, or this won't work):
$(document).ready(function () {
$('.execute').each(function() {
advertisement(this); //change to whatever the advertisement script function is called.
});
});
Hopefully that will get you started. I can't really help you much more without knowing more about the advertisement script, though.
Also, the people who supplied the advert script should be able to tell you how to use it.
I believe a Javascript library like JQuery or Dojo is what you are looking for. It will allow you to add event handlers on tags with certain CSS attributes, which will behave exactly like what you are trying to do right now.
EDIT
Here is an example with Dojo pulled from the Google CDN that will popup an alert window when you click on any <div class="execute"></div> block:
<html>
<head>
<style>
<!--
.execute { background-color: red; height: 25px; }
-->
</style>
<script src="http://ajax.googleapis.com/ajax/libs/dojo/1.6.0/dojo/dojo.xd.js" ></script> <!-- load Dojo from Google CDN
<!-- Let's register a onClick handle for any .execute div. -->
<script>
dojo.ready(function() // Dojo will run this after being initialized
{
// Get A list of all tags with id execute and add a event onClick
dojo.query(".execute").connect("onclick", function(evt)
{
alert("Event triggered!");
// ...
});
});
</script>
</head>
<body>
<div class="execute">Click me 1</div>
<br /><br />
<div class="execute">Click me 2</div>
</body>
</html>
Edit 2
This example uses an onClick event but Dojo (JQuery) allows you to do much more things. For instance if you wanted to dynamically add an image or something onLoad inside .execute divs, you could do it with Dojo (JQuery) in a similar way to this.
Doing it with a library saves you a lot of effort, but if you still want to write and call your own functions from javascript files, this is a rough idea of how you would do it:
// myScript.js
function foo()
{
// ...
}
// page.htm
<html>
<head>
<script src="path/to/myScript.js"></script>
</head>
<!-- ... -->
<div class="execute">
<script>
<!--
// Call foo()
foo();
-->
</script>
</div>
<!-- ... -->
It doesn't really make sense to abstract a script into CSS like that, and even if it was a good idea, it can't be done.
Why do you need to run the same script over and over in different places? Consider whether or not there might be a better or simpler way to do whatever it is you're doing.
Plus, when you include a script with the src attribute in the script tag, if you modify the script's source file, the changes persist everywhere.
No, but you can use script to alter the CSS properties of any element in the DOM.
I am trying to throw together a website using Ajax for the first time, to finally get with the times and figure it out. So far it is nothing but HTML pages and a bit of JS. Using some basic AJAX script I found online, I have the main index.htm which has a title, navigation, and content divs. The Ajax calls grab other content includes (which are just files with text content for the most part) to throw into the content div. For the most part it works, except for when I am trying to add the Google Directions gadget. When I add the script code it gives me to a file and call that file, there is no noticeable output.
Any suggestions on what I am doing wrong or what I'm missing?
If I am understanding you correctly this is an unnecessary use of AJAX. From what it seems like you want to do is load JavaScript via a JavaScript call. This can be accomplished using either method described here. Example:
<script type="text/javascript">
function dhtmlLoadScript(url)
{
var e = document.createElement("script");
e.src = url;
e.type="text/javascript";
document.getElementsByTagName("head")[0].appendChild(e);
}
onload = function()
{
dhtmlLoadScript("dhtml_way.js");
}
</script>
If the above link does not help or I am misunderstanding your question please provide further clarification or some sort of code example.
Following up on your comment
Here is a work around for your gadget, the below code would be on your main page (the one that is initially loaded). Here is my test HTML page:
<html>
<head>
<script type="text/javascript">
var gadget;
function getGadgetAndMove(node)
{
gadget = document.getElementsByTagName("table")[0];
node.appendChild(gadget);
gadget.style.visibility = "visible";
gadget.style.display = "inline-block";
}
</script>
<style>
.ig_reset, .ig_tbl_line { visibility:hidden;}
</style>
</head>
<body>
<div onclick="getGadgetAndMove(this);">Test</div>
</body>
<script src="http://www.gmodules.com/ig/ifr?url=http://hosting.gmodules.com/ig/gadgets/file/114281111391296844949/driving-directions.xml&up_fromLocation=&up_myLocations=1600%20Amphitheatre%20Pkway%2C%20Mountain%20View%2C%20CA&synd=open&w=320&h=55&title=Directions+by+Google+Maps&brand=light&lang=en&country=US&border=%23ffffff%7C3px%2C1px+solid+%23999999&output=js"></script>
</html>
If you need further explanation please let me know.
I believe I know what you want to accomplish, because I ran into the same problem. And I found a solution. So I would say that no it is not an improper use of ajax, because you could run into this in some circumstances.
Put the directions gadget not directly in the page content that is being loaded via ajax, but in a separate file such as "directionsgadget.html" (insert the script tag for the gadget in this file).
Then use an iframe with src="/path/to/directionsgadget.html" in your ajax loaded content.
The gadget should get loaded this way.
If you want the gadget centered within the iframe, you can wrap the script tag in directionsgadget.html in a div with a set width and style="margin:0px auto". That will center the gadget.
Here is an example:
Your main page is "index.html", and contains a div that will contain ajax loaded content:
<!DOCTYPE html>
<html>
<head>
<script type="text/javascript">
$(document).ready(function(){
$.ajax({
url: 'ajaxcontent.html',
success: function(returndata){ $('#ajaxcontent').html(returndata); }
});
});
</script>
</head>
<body>
<div id="ajaxcontent"></div>
</body>
</html>
Then you have a file with the content that is to be loaded via ajax, and this has among other things a google gadget. Were not going to put the gadget directly here, but were going to put it in a separate file and point to it with an iframe. Let's call this first file ajaxcontent.html, as indicated in the ajax call in the head section of the first file:
<span>Here is some content that will be loaded onto the main page via ajax.</span><br />
<span>Among other things, there is a google directions gadget that will be loaded.</span>
<div id="getdirections" style="margin:0px auto;">
<iframe style="width:365px;height:216px;" src="directions.html"></iframe>
</div>
Now we will put the script for the google gadget itself in a separate file "directions.html" (as indicated in the src of the iframe above), and in order for the rendered gadget to be centered we are going to wrap the script tag within a div just so:
<div style="width:336px;height:116px;margin:0px auto;">
<script type="text/javascript" src="http://www.gmodules.com/ig/ifr?url=http://hosting.gmodules.com/ig/gadgets/file/114281111391296844949/driving-directions.xml&up_fromLocation=&up_myLocations=_a_bunch_of_information_with_personal_list_of_locations_&synd=open&w=320&h=55&title=Street+directions+by+Google+Maps&brand=light&lang=it&country=ALL&border=http%3A%2F%2Fwww.gmodules.com%2Fig%2Fimages%2F&output=js"></script>
</div>
I hope this example was clear enough!
