    Hi again.

    Sorry to bother you again with the same topic, but i worked on my page and tried to add up what I have learned. But something did not work. Could you tell me what i did wrong?

    I wanted to see if it would work without putting any adress on the "action" mode. But it doesn't.

    Thank you.

    I know it is supposed to make appear a pop-up window saying that I have to type my name, if I want to post the fromular. But no, I don't have a servo and demo_form asp file. I'm just a beginner learning html, xhtml, css and now javaScript. I realised a website still, but i want to intrioduce a contact form and want to use this javaScript to realize this pop-up window. I uesd my e-mail adress instead, but the result was the same.

    Hi,

     

    I am still studying JavaScript, I am learning validation form.

    Then i do this exercise: (on W3C of course)

     

    I write on my Notepad++ (language HTML)

     

    <!DOCTYPE html><html><head><script>function validateForm() { var x = document.forms["myForm"]["fname"].value; if (x==null || x=="") { alert("First name must be filled out"); return false; }</script></head><body><form name="myForm" action="demo_form.asp" onsubmit="return validateForm()"method="post">First name: <input type="text" name="fname"><input type="submit" value="Submit"></form></body></html>

     

    So on the action="demo_form.asp" (which I put deliberatly on bold so you can see what i mean) when i press the button "Submit"

    The browser answers :

     

    File not foundFirefox can't find the file at (then the place where I store my files) Check the file name for capitalization or other typing errors. Check to see if the file was moved, renamed or deleted.

     

    If I put a valid e-mail adress, it goes directly to thunderbird firefox which i use. How can I verify my exercice otherwise?

    I have a problem to make work javascript

    in JavaScript

    Hi everybody,

     

    I am learning javascript on this website. But when I did that simple exercice in the begining, it did not work.

     

    <!DOCTYPE html><html>

    <head>

    <script>function myFunction() { document.getElementById("demo").innerHTML = "Paragraph changed.";</script>

    <body><script src="jvsTest.js"></script><h1>My Web Page</h1><p id="demo">A Paragraph</p><button type="button" onclick="MyFunction()">Try it</button></body></html>

     

    When you go to the demo page, you click on the button and it changes from: 'A paragraph' to 'Paragraph changed'.

     

    so I tried it and (I use notepad++) it didn't work. I did like above, then with javascript in the <body> section, then on a separate sheet with javascript language. Still, it didn't work.

     

    As a matter of fact, I tried the other javascripts I wrote, did not work either. My browser is Firefox, I disabled the block pop up window and tried it on Explorer and Google Chrome, and nothing works. So what could be the problem?

    Why it does not work?
