Accessing Form
JavaScript provides various ways of accessing form:-
- document.forms[index_number] – It returns collection of form in the documents.
- document.forms[“name_attribute_value”] – we can use name attribute of the form.
- document.name_attribute_value – we can use name attribute of the form with dot as well.
- getElementById(“ID”) – If form as an unique id we can use it.
Accessing Form Fields
If form fields have unique ID then it is possible to access them using the getElementById( ) method. However, There are some other ways: –
- elements[ ] – It contains collection of form fields.
Syntax: –
document.form_name.elements[index_number];
document.form_name.elements[“name_attribute_value”];
document.form_name.name_attribute_value;
document.form_name.ID_attribute_value;
- getElementsByName(“field_name”) – This method is also used to access form field.
