Chrome Developer Tools has a Properties tab which shows useful DOM attributes.
Also see MDN for a reference.
See an example in this jsFiddle.
Also, and seeing you’re starting to learn HTML, you might consider using console.log() instead of alert() for debugging purposes. It doesn’t interrupt the execution flow of the script, and you can have a general view of all logs in almost every browser with developer tools (except that one, obviously).
It’s not because you are using alert, it will happen when use document.write() too. This problem generally arises when you name your id or class of any tag as same as any variable which you are using in you javascript code. Try by changing either the javascript variable name or by changing your tag’s id/class name.
My code example: bank.html
Javascript code: bank.js
you can have a look and understand the concept from my code. Here i have used a variable named ‘amt’ in JS. You just try to run my code. It will work fine but as you put an [id=»amt»](without square brackets) (which is a variable name in JS code )for div tag in body of html you will see the same error that you are talking about. So simple solution is to change either the variable name or the id or class name.

Note: Depending upon the environment in which the page is being viewed, the value property may be read-only for the file upload input type. For the «password» input type, the actual value returned may be masked to prevent unauthorized use. See the INPUT element definition in [HTML 4.01].
A comma-separated list of content types that a server processing this form will handle correctly.
Implementation
public function get accept():DOMString
public function set accept(value:DOMString):void
A single character access key to give access to the form control.
Implementation
public function get accessKey():DOMString
public function set accessKey(value:DOMString):void
Aligns this object (vertically or horizontally) with respect to its surrounding text.
Implementation
public function get align():DOMString
public function set align(value:DOMString):void
Alternate text for user agents not rendering the normal content of this element.
Implementation
public function get alt():DOMString
public function set alt(value:DOMString):void
When the type attribute of the element has the value «radio» or «checkbox», this represents the current state of the form control, in an interactive user agent. Changes to this attribute change the state of the form control, but do not change the value of the HTML checked attribute of the INPUT element.
Note: During the handling of a click event on an input element with a type attribute that has the value «radio» or «checkbox», some implementations may change the value of this property before the event is being dispatched in the document. If the default action of the event is canceled, the value of the property may be changed back to its original value. This means that the value of this property during the handling of click events is implementation dependent.
Implementation
public function get checked():Boolean
public function set checked(value:Boolean):void
When type has the value «radio» or «checkbox», this represents the HTML checked attribute of the element. The value of this attribute does not change if the state of the corresponding form control, in an interactive user agent, changes.
Implementation
public function get defaultChecked():Boolean
public function set defaultChecked(value:Boolean):void
When the type attribute of the element has the value «text», «file» or «password», this represents the HTML value attribute of the element. The value of this attribute does not change if the contents of the corresponding form control, in an interactive user agent, changes.
Implementation
public function get defaultValue():DOMString
public function set defaultValue(value:DOMString):void
The control is unavailable in this context.
Implementation
public function get disabled():Boolean
public function set disabled(value:Boolean):void
Returns the FORM element containing this control. Returns null if this control is not within the context of a form.
Implementation
public function get form():HTMLFormElement
Maximum number of characters for text fields, when type has the value «text» or «password».
Implementation

The onblur event occurs when an element loses focus either by the pointing device or by tabbing navigation.
Implementation
public function get onblur():Function
public function set onblur(value:Function):void
The onchange event occurs when a control loses the input focus and its value has been modified since gaining focus.
Implementation
public function get onchange():Function
public function set onchange(value:Function):void
The onfocus event occurs when an element receives focus either by the pointing device or by tabbing navigation.
Implementation
public function get onfocus():Function
public function set onfocus(value:Function):void
The onselect event occurs when a user selects some text in a text field.
Implementation
public function get onselect():Function
public function set onselect(value:Function):void
This control is read-only. Relevant only when type has the value «text» or «password».
Implementation
public function get readOnly():Boolean
public function set readOnly(value:Boolean):void
Size information. The precise meaning is specific to each type of field.
Implementation
public function get size():Number
public function set size(value:Number):void
When the type attribute has the value «image», this attribute specifies the location of the image to be used to decorate the graphical submit button.
Implementation
public function get src():DOMString
public function set src(value:DOMString):void
Index that represents the element’s position in the tabbing order.
Implementation
public function get tabIndex():Number
public function set tabIndex(value:Number):void
The type of control created (all lower case).
Implementation
public function get type():DOMString
public function set type(value:DOMString):void
Use client-side image map.
Implementation
public function get useMap():DOMString
public function set useMap(value:DOMString):void
When the type attribute of the element has the value «text», «file» or «password», this represents the current contents of the corresponding form control, in an interactive user agent. Changing this attribute changes the contents of the form control, but does not change the value of the HTML value attribute of the element. When the type attribute of the element has the value «button», «hidden», «submit», «reset», «image», «checkbox» or «radio», this represents the HTML value attribute of the element.
Implementation
public function get value():DOMString
public function set value(value:DOMString):void
