Hello,

This is my first post to CodeProject. Please excuse if I commit some CodeProject "nono's," but point them out if you wish.

Anyways, I need help. I have only ever used <script> </script> in an html document to add functionality to a web page. But, I was recently given the task of implementing all of my JavaScript work from an outside .js file.

Here is what I know. I know I'll have to create and external .js file, and link it from my html. But what should it look like? I've never worked with raw JavaScript files before.

Here is my code:

<form name="myForm"> <!--calling the form a name allows the capturing and manipulating of user-entered values -->
	<fieldset id="inputs"> <!-- fieldset used to the effect of a container for CSS -->
    <ul> <!-- an unordered list is a great way to create text fields. Note that the default CSS inserts bullet points before the text field, a telltale sign of a list -->
	<li> 
    	<label for="principal"> Principal(p): </label>
        <input type="number" id="principal" name="principal" min="1" max="1,000,000"> <!-- "text" input type has the browser know that the user will...input text. An id and name are assigned along with type -->
    </li>
    
    <li>
    	<label for="intRate">  Yearly Interest Rate(r) (Enter as a decimal): </label>
        <input type="text" id="intRate" name="intRate" placeholder="0.00" min="0" max="1"> <!-- the user must type in a number in between the min and max values -->
    </li>
    
    <li>
    	<label for="length"> Loan Length(years): </label>
        <input type="number" id="length" name="length" min="1" max="100">
    </li>
    
    <li> 
    	<input id="clickme" type="button" value="Your Monthly Fate" onclick="loanPayment()"> <!-- creates a submit button, called "Flip the script!" Once clicked, the button will act-out the function storyTime() from the JavaScript in the head -->
     </li>
     </fieldset>
     
     <fieldset id="output">
     <li>
        <input type="text" id="result" name="result">
     
     </li>
     </fieldset> 
    
</ul>

A pretty standard form with some amateur comments. This all would normally go in the body of my html doc. Next, here's the function and variables within the <script> tags of the head:

<script>

	function loanPayment() //function to be actioned-out in the body on a button
	{
		
		var principal = document.getElementById("principal").value;
		var intRate = document.getElementById("intRate").value;        //calls the ids of the list items and gets their values
		var length = document.getElementById("length").value;
		
		var R = intRate/12; //Takes the interest rate and separates it for each month. The intRate must be expressed as a decimal. i.e. 6% = 0.06 
		var Y = length*12; //expresses the years of loan length in months -->
		
		var W = Math.pow((1+R),Y); //Takes the new variables R and Y and brings the value of 1+R to the power of Y -->
		//var z = Math.pow(x,y) is saying Z = x^y
		
		var F = (R * principal * W)/(W - 1); 
		F = F.toFixed(2); //rounds and expresses answer to two decimal places. 
		
		
		document.getElementById("result").value = "Monthly Fate = $" + F; //prints a generic string of text followed by the answer in a text field
	
	}

</script>

How would this form be implemented into an html web page through the use of an external .js file? I'm very new to html/css/JS and I want to get it right. Thank you all and please try to be as detailed as possible; what's common sense to you might not be to me.

var tabs = require('sdk/tabs');

tabs.on('ready', function (tab) {
     tab.attach({
        contentScript: "alert('azaza');",
        onMessage: function(message) {
            console.log("message");
        }});
}

function start()
{
   var theArray = [ 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 ];
   var total1 = 0, total2 = 0;


   var length = theArray.length;

   for ( var i = 0; i < length; ++i )
   {
      total1 += theArray[ i ];
   }


   var results = "<p>Total using indices: " + total1 + "</p>";

   for ( var element in theArray )
   {
       total2 += theArray[ element ];
   }

   results += "<p> Product using indices: " + total2 + "</p>";
   document.getElementById( "output" ).innerHTML = results;
}

window.addEventListener( "load", start, false );

$('#widgetCalendar').DatePicker({
            flat: true,
            format: 'd B, Y',
            date: [new Date(now3), new Date(now4)],
            calendars: 3,
            //mode: 'range',
            starts: 1,
            onChange: function(formated) {
                $('#widgetField span').text(formated);
                // $("input[name='DTTBox']").text(formated);
            }
        });

What I have tried is to set the span style="display:none" and used a textbox to receive the date which does not work:

<span style="display:none;"><asp:TextBox id="MyHiddenTextBox" runat="server" /><span>


Thanks,



Steve

var a = [{"Id": 1, "Name": 'a'}, {"Id": 2, "Name": 'b'}, {"Id": 3, "Name": 'c'},{"Id": 4, "Name": 'd'},,{"Id": 5, "Name": 'j'}];
var b = [{"Id": 1, "Name": 'a'}, {"Id": 4, "Name": 'd'}, {"Id": 5, "Name": 'j'},{"Id": 9, "Name": 'i'}];

I need to remove duplicate in "a" by comparing "a" with "b" using underscore js
