document. The variable role is unknown.

I am studying javascript while looking at the site.
document.myForm.myLine.value=myInput;
I don't know what the line is doing.
"The description says ""Display the value you are currently entering"", but why do I write "" document.variable…"" to display the value in html?"
The document came out when I checked that HTML elements that make up the web page can be easily accessed from the program, but how do you access them in this case?
javascript
You can't tell that by looking at the definition of the function function myValue(myData).
I think the HTML code is written at the back, but I think you can find name=myForm and name=myLine.
In function myValue(myData), myFrom and myLine refer to that part of the HTML code.
In other words, document.myForm.myLine.value represents the <formname="myForm">>...</form> table of <<input type="text"size="12"name="myLine"value="0">code> in HTML.
Because the Document object corresponds to named properties
<form name="myForm"...>
You can access the element in document.myForm if is present.
Similarly, the Form element corresponds to named properties, so
<form name="myForm"...>
...
<input name="myLine".../>
...
</form>
You can access the element in document.myForm.myLine if is present.
