Mustache.js - using partial inside an external template file

I'm using external template file and I want to use a partial inside the template file (.mst file inside another .mst file)
For example I have template.mst file with this code:
{{#comments}}
// Here I want to use another external .mst file
{{/comments}}
So I careated a comment.mst file beside the template.mst file and now I'm trying to use {{>comment}} to call this external template file - full example:
{{#comments}}
{{>comment}}
{{/comments}}
But it doesn't work. I tried to play with it a little bit, I tried to add the file extension {{>comment.mst}} and I tried to add the path {{>temmplates/comment}} and any pther option.
This is the code I use to load the template:
$.get('templates/template.mst', function(template) {
var rendered = Mustache.render(template, postData);
$('.inner-container').prepend(rendered);
});
I guess I missing something, Can someone give me an hint? Thanks!

Get filename from input file in Javascript

I have noticed that bootstrap is able to parse out and display the top level filename from a file input field when the user selects a file.
<input type="file" id="exampleFile">
JSFiddle: http://jsfiddle.net/na4j7n6y/
My question: Is this functionality exposed for me to use in my own javascript code? Or do I have to parse out the filename once again using my own technique?
I have tried retrieving the filename like so:
$('#exampleFile').val()
// Resolves to 'C:\fakepath\FILENAME' instead of 'FILENAME'

Well, bootstrap is a framework based on html, css and javascript. The javascript part of this framework uses jQuery and not a own library. Then you could try to solve it using a regex with javascript/jquery, for sample:
var fullPath = $("#exampleFile").val();
var filename = fullPath.replace(/^.*[\\\/]/, '');

How to get the file name from a full path using JavaScript?

Check this JSFiddle to reference the filepath displayed.

JS
function getAfilepath(){
var afilepath = document.getElementById("uploadFile").value;
document.getElementById("write").innerHTML=afilepath;
}

Javascript dynamically show local file

I have a local text file which is kept changing by other programs. I want to write a html and javascript based web page to show the content of file dynamically. I have searched in google and found that most solutions require to get this text file via html element. I wonder if there is a way to get the file via a fixed path(lets say it is a string of the file directory) in javascript. I am using Javascript fileReader. Any help will be appreciated.

This is not possible using javascript running inside the browser. You will not be able to do anything outside the browser.
EDIT:
You could run a Node.js server though that runs on localhost and does your file operations you desire. You could build a API so your html page that you load in the browser calls your serverscript to do your file operations.
Do you understand what I mean?

How much information does the text file hold, Depending on your scenario it might be worth looking into javascript localstorage W3SCHOOLS local storage. Would that help your situation ?

What you can do is allow the user to choose the file of interest, using a file-input. Once done, the browser wil have access to the file, even though the JS wont have access to the file's full-path.
Once the user has chosen the file, you can reload it and refresh the view pretty-much as often as you please.
Here's a short demo, using a file input (<input type='file'/>) and an iframe. You can pick pretty much anything the browser will normally display, though there are limits on the size of the file that will work - due to the limit of the length of a URL - the file's data is turned into a data-url and that url is set as the source of the iframe.
As a demo, pick a file and then load it. Now, open the file in another program and change it. Finally, press the load button once again - the new content now fills the iframe. You can trigger the loading of the file by a timer or any other event in the page. As far as I'm aware, you cannot re-load it when it changes, since there's no notification from the OS - you have to use a button, timer, element event or whatever. Basically, you have to poll for changes.
<!DOCTYPE html>
<html>
<head>
<script>
function byId(e){return document.getElementById(e);}
window.addEventListener('load', onDocLoaded, false);
function onDocLoaded()
{
// uncomment this line for on-demand loading.
byId('loadBtn').addEventListener('click', onLoadBtnClick, false);
}
// fileVar is an object as returned by <input type='file'>
// tgtElem is an <iframe> or <img> element - can be on/off screen (doesn't need to be added to the DOM)
function loadFromFile(fileVar, tgtElem)
{
var fileReader = new FileReader();
fileReader.onload = onFileLoaded;
fileReader.readAsBinaryString(fileVar);
function onFileLoaded(fileLoadedEvent)
{
var result,data;
data = fileLoadedEvent.target.result;
result = "data:";
result += fileVar.type;
result += ";base64,";
result += btoa(data);
tgtElem.src = result;
}
}
function onLoadBtnClick(evt)
{
var fileInput = byId('mFileInput');
if (fileInput.files.length != 0)
{
var tgtElem = byId('tgt');
var curFile = fileInput.files[0];
loadFromFile(curFile, tgtElem);
}
}
</script>
<style>
</style>
</head>
<body>
<button id='loadBtn'>Load</button><input id='mFileInput' type='file'/><br>
<iframe id='tgt'></iframe>
</body>
</html>

you can use nodejs to watch for a filechange using watchfile module, if you just want to watch the filechange and its content. you can run following code using node, but it only consoles the file changed in your terminal.
var fs=require('fs');
fs.watchFile('message.text', function (curr, prev) { //listens to file change
fs.readFile('message.text', function(err,data){ //reads the file
console.log(data.toString()); //consoles the file content
});
});

Javascript File from Local Storage

I have a large JavaScript file that I'd rather not send to the client on each request and it's too large for the browser to cache.
My thought is that I will save the file to HTML5 local storage and attempt to retrieve it. If the file is found then I'd like to link/import/export(I don't know the proper terminology) it into the same scope that a html src tag would.
My question is: how do I take a file that I've pulled from local storage and get my webpage to recognize it as a JavaScript file that was included via src tag? (minus the logic for pulling the file from storage)

My question is: how do I take a file that I've pulled from local storage and get my webpage to recognize it as a JavaScript file that was included via src tag?
Two possible ways (amongst maybe others):
create a script element, and assign your JS code as the “text content” of that element before appending it to the DOM. “Text content” in quotes here, because it is not as simple as it sounds cross-browser – see f.e. Javascript script element set inner text, Executing elements inserted with .innerHTML, or
assign your script code to the src attribute of a script element via a Data URI, data:text/javascript,… – but that approach has several disadvantages as well, also mostly in older IE (size limitation; only “non-navigable” content, meaning no scripts). But depending on your target environment that might well work. You will not necessarily need to base64 encode the script code, URL-percent-encoding via encodeURIComponent should work as well.

Take a look at this:
http://jsfiddle.net/611e96mz/1/
var tag = getId('testjs'),
a = getId('a'),
b = getId('b'),
c = getId('c'),
script;
a.addEventListener('click', function () {
localStorage.setItem('js', tag.innerHTML);
});
b.addEventListener('click', function () {
script.textContent = localStorage.getItem('js');
});
c.addEventListener('click', function () {
document.body.appendChild(script);
alertMe();
});
var script = document.createElement("script");
script.type = "text/javascript";
function getId(x) {
return document.getElementById(x);
}

You can use JSON to stringfy your file content and put it on localstorage.
var content = JSON.stringify([1, "some info"]); // '[1,"some info"]'
localStorage.setItem('fileContent', content);
// Retrieve
var content = localStorage.getItem('fileContent');

Read and display the text file contents upon click of button using Javascript

On click of a button called result, I want to read and display a text file (which is present in my local drive location say: C:\test.txt) using Javascript function and display the test.txt file contents in a HTML text area.
I am new to Javascript,can anyone suggest the code for Javascript function to read and display the contents of .txt file?

An Ajax request to a local file will fail for security reasons.
Imagine a website that accesses a file on your computer like you ask, but without letting you know, and sends the content to a hacker. You would not want that, and browser makers took care of that to protect your security!
To read the content of a file located on your hard drive, you would need to have a <input type="file"> and let the user select the file himself. You don't need to upload it. You can do it this way :
<input type="file" onchange="onFileSelected(event)">
<textarea id="result"></textarea>
function onFileSelected(event) {
var selectedFile = event.target.files[0];
var reader = new FileReader();
var result = document.getElementById("result");
reader.onload = function(event) {
result.innerHTML = event.target.result;
};
reader.readAsText(selectedFile);
}
JS Fiddle

Using $.ajax() function: http://api.jquery.com/jQuery.ajax/
$(function(){
$.ajax({
url: "pathToYourFile",
async: false, // asynchronous request? (synchronous requests are discouraged...)
cache: false, // with this, you can force the browser to not make cache of the retrieved data
dataType: "text", // jQuery will infer this, but you can set explicitly
success: function( data, textStatus, jqXHR ) {
var resourceContent = data; // can be a global variable too...
// process the content...
}
});
});

As You've mentionned HTML, I assume you want to do this in a browser; Well the only way to access a local file in a browser is by using the File API, and the file can only be obtained via a user's manipulation such selecting a file in an <input type='file'> element, or drag&dropping a file in your page.

We could achieve this by, I should say, creating a virtual file!
Storing the contents of the text file into a Javascript string variable. However, one should consider all new lines and other special symbols\characters and etc.!
We than can markup a script tag in our HTML to load that *.js Javascript like this:
<script src="my_virtual_file.js"></script>
The only difference here is that a text file that could contain:
Goodnight moon
Follow the white rabbit
In a Javascript script string variable should look like this:
var my_virtual_file = "Goodnight moon\nFollow the white rabbit";
Later on, you can access this variable and treat it as you wish...
A programming language like Javascript that follows standards like ECMAScript, gives you a wide range of capabilities to treat and convert data from one type into another.
Once you have your Javascript script loaded, you can then access that variable by any button in your HTML by assigning a function call on its onclick attribute like this:
<button onclick="MyVirtualFile()"></button>
And ofcourse, you just add a script tag to your HTML, like this:
<script>
functiion MyVirtualFile(){
alert(my_virtual_file);
};
</script>
... or your may just create and import another Javascript script containing that same function, under your desire.
If you are concerned about how much information you can store into a Javascript string variable, just take a look at this interesting (and old as this one :D) SO thread.
Lets see if this snippet works :):
var my_virtual_file = "Goodnight moon\nFollow the white rabbit"
function MyVirtualFile(){
alert(my_virtual_file);
// Do anything else with your virtual file
};
<!DOCTYPE html>
<html>
<head>
<script src="my_virtual_file.js">
</script>
</head>
<body>
<h1>HTML Javascript virtual file</h1>
<button onclick="MyVirtualFile()">Alert my_virtual_file</button>
</body>
</html>
You can programatically access and dynamically change the contents of your Javascript script, but you should remind that you need to reload your HTML so the browser can load the new contents.
On your filesystem, you can just treat this *.js as a *.txt file, and just change its contents keeping in mind the Javacript.
