How do I get Javascript and HTML to communicate?

Is there any way for me to take an input box value in HTML, and use it in Javascript?How do I get Javascript and HTML to communicate?
Several ways depending on what you are trying to do and how. No code given so not gonna guess.

It's called the DOM, Document Object Model.



Basically Javascript can call just about any property, value, position, anything from HTML.



If you want a form field value easy:

document.form_id.field_name.value



Want to change the color of a font:

document.getElementById('element_id').?=';#fff';;



Change the text of a link:

document.getelementById(';link_id';).inn?= ';New Link';;



And the best part about the DOM is that it is logically written. If you think you can write something you probably can. Just look at my examples.
Inside the %26lt;script%26gt; element write the code of the javascript function and place the document design in the %26lt;body%26gt; tag.

That's not really possible. I've tried. But if your looking for HTML stuff go to justin-productions.webs.com. They say they have some good html, but I dont see sum, but if you request for html they give it to you via email.
%26lt;form name=';form1'; onchange=';func1();';%26gt;

%26lt;input type=';text'; name=';val1';%26gt;%26lt;/input%26gt;

%26lt;/form%26gt;



in js:

function func1() {

if (document.form1.val1.value == ';something';) {

...

}

...

}
