Kaj je JavaScript?
  • JavaScript je skriptni jezik za spletne strani.
  • Skripte napisane v JavaScriptu vključimo direktno v HTML dokument.
  • Sintaksa ukazov JavaScripta je podobna jeziku C++
Obika zapisa: <script language="JavaScript"><!--
ukaz1; ukaz2; ukaz3;
// --></script>

JavaScript koda se lahko nahaja tudi v posebni datoteki - ta se med izvajanjem avtomatsko vključi v spletno stran
<SCRIPT SRC="koda.js"> </SCRIPT>
1. Pošiljanje e-pošte iz domače strani:

 

<form action="mailto:[email protected]" method="post" enctype="text/plain" name="F1">
<textarea name="S1" rows="3" cols="30"> </textarea><br>
<input type="submit" name="B1" value="Poslji">
<input type="reset" name="B2" value="Zbriši">
</form>
2. Stran zaščitena z geslom (simple varianta):

 

function geslo()
{
var s;
s=document.F2.T1.value;
if (s=="pravo")
{ document.location="http://mpulko.tripod.com"; }
else
{ alert ("napacno geslo"); }
}

<input type="button" name="B1" value="OK" onclick="geslo()">

 
3. Pretvorba inčev v cm:

inč= cm

 

function pretvori()
{
var x, y;
x=parseFloat(document.F3.T1.value);
y=x/2.54;
document.F3.T2.value=y;
}
<input type="button" name="B1" value="Pretvori" onclick="pretvori()">

 
4. Spreminjanje slik

var slika1=new Image();
var slika2=new Image();
slika1.src="smile.gif";
slika2.src="vprasaj.gif";

<a href="javascript:alert('Alo');" onmouseover="document.S1.src=slika2.src;" onmouseout="document.S1.src=slika1.src;"> <img src="smile.gif" border="0" name="S1"> </a>

 
5. Kocka - naključna števila

 

function kocka()
{
var x;
x=parseInt(1+6*Math.random());
document.F4.T1.disabled=1;
document.F4.T1.value=x;
}

<input type="button" name="B1" value="OK" onclick="kocka()">

 
6. Barva ozadja

ugasni luč prižgi luč

 

function prizgi()
{
document.bgColor='white';
}

function ugasni()
{
document.bgColor='black';
}

<input type="radio" name="R1" value="V1" onclick="ugasni()">
<input type="radio" checked name="R1" value="V2" onclick="prizgi()">

 
7. Tabela (Array)

 

function tabela()
{
var a=new Array(3);
for (var i=0; i<3; i++)
{ a[i]=parseInt(prompt("vnesi "+i+" stevilo: ","")); }
for (i=0; i<3; i++)
{ document.F6.S1.value+=a[i]+"\n"; }
}

<input type="button" name="B1" value="Start" onclick="tabela()">

 
8. Dodaj med priljubljene (Bookmark)

 

function bookmark()
{
window.external.AddFavorite(this.location.href,this.document.title);
}

<input type="button" name="B1" value="Bookmark" onclick="bookmark()">

 
9. Novo okno (pop up window)

 

function popup1()
{
var t=new Date();
var ss="<HEAD><TITLE>Vaja</TITLE></HEAD><BODY><FONT size='6' color='red'>"+t.getTime()+"</FONT></BODY>";
okno=window.open("","","scrollbars=0, toolbar=0, status=0, menubar=0, rezisable=0, location=0, directories=0, width=200, height=100");
okno.document.write(ss);
okno.document.close();
}

function popup2()
{
okno=window.open("index.htm","okno","scrollbars=1, toolbar=1, status=1, menubar=0, rezisable=0, location=1, directories=0, width=400, height=300");
okno.document.close();
}

<input type="button" name="B1" value="popup1" onclick="popup1()">
<input type="button" name="B2" value="popup2" onclick="popup2()">

(datoteka z nekim podatkom, ki se shrani na računalnik obiskovalca spletne strani)

if (value != null && value != "")
document.cookie = ime + "="+escape(value) + "; expires=" + datum2.toGMTString();
}

function getCookie(ime)
{
if (document.cookie.length>0)
{
var index = document.cookie.indexOf(ime+"=");
if (index == -1) return null; // Cookie ne obstaja
index = document.cookie.indexOf("=", index) + 1;

if (endstr == -1) endstr = document.cookie.length;
alert (unescape(document.cookie.substring(index, endstr)));
}
}

<input type="button" name="B1" value="Pošlji Cookie" onclick="setCookie('mpulko','1')">

Dogodki (Events):

na obrazcih (forms)
onFocus - an event is triggered with a form object gets input focus (the insertion point is clicked there)
onBlur - an event is triggered with a form object loses input focus (the insertion point is clicked out of there)
onChange - an event is triggered when a new item is selected in a list box. This event is also trigged with a text or text area box loses focus and the contents of the box has changed
onSelect - an event is triggered when text in a text or text area box is selected
onSubmit - an event is triggered when the form is submitted to the server
onClick - an event is triggered when button is clicked

na dokumentu (document)
onLoad - <body onload="go()">
onUnload - <body onunload="go()">

Lastnosti:

focus() - Equivalent to clicking this field document.F1.T1.focus();
blur() - Equivalent to clicking another field after using this one
select() - Equivalent to dragging the mouse across all the text in this field-selecting it
submit() - Equivalent to click Submit button document.F1.submit();
