How to make a web program running
a) Edit a program ( to type) can be edited in notepad, geocities (web hosting), FrontPage, and anything that lets you save it as a text.( ex: word pad, Microsoft word)
b) Interpreter a program ( make understandable for computer (activate))
We are going to use Java or VBscript and browsers understand these 2 languages
Compiler- takes whole program and translates it. example: C++
Interpreter- translate sentence by sentence
Java script is built into HTML.
Language there is decision making
Every HTML you should have head and you should have body.
Head it to put program there
Body to activate the program
When there is an error in code in preview this message pops up
Char: the column
Syntax error: wrong spelling
Script language is used for validation( check for error) because data is in the server
Code
<html>
<title>figure it out</title>
<head>
<script language= "javascript">
function buttonPressed()
{
searchForm.result.value ="Match not found";
document.write ("Match found");
return -1;}
</script>
</head>
<body>
<form name="searchForm"><p> ENTER THE PERSON'S ID <br>
<input name="inputVal" type="text" size="32">
<input name = "search" type= "button" value= "Just Do IT"
oneclick= buttonPressed()"><br></p>
<p> result <br>
<input name= "result" type="text" size="30"></p>
</form>
</body>
</html>
