The difference between document.all and document.forms [0]

Question

Can anyone explain what is the difference between

document.all 

and document.forms[0] please?

thanks

Answer 1

document.all provides a reference to an object that looks like an array containing all the elements of a document in Internet Explorer (IE). Document.forms[0] gives a pointer to the first form element in the document, in all browsers

At the same time 2. If your form had a name attribute, say "myform", then in IE this form can be specified using document.all.myform

document.all deprecated from IE version 5 and above. You can still use it, although it is still available in IE9. Often it is used to check if the IE browser is:

 if (document.all) { //o no, it IE again! We have to do it another way! } 

Linking to forms in the form Document.forms[0] is considered bad practice. Learn more about this here.

NOTE. Since this answer was first written, IE11 was introduced which refused to support document.all . See Compatibility Changes in IE11 for More Information.

Answer 2

The document.all property is an array of all HTML elements that are in the document. and Document.forms [0] is the first form of the document. You should avoid using document.all.

Internet Explorer 4 introduced document.all DOM (Document Object Model) to provide access to various parts of a web page. Soon after, the standard DOM method getElementById was introduced and therefore available in all browsers of version 5+. This means that document.all links are only necessary for IE4 support. It’s just that no one starts IE4 anymore and so document.all DOM support no longer exists. required.
