validateTag()

Availability

Dreamweaver MX.

Description

When a user clicks on a node in the tree control or clicks OK, the function performs input

validation on the currently displayed HTML form elements.

Arguments

None.

Returns

Dreamweaver expects a Boolean value: true if the input for HTML form elements is valid;

false if input values are not valid.

Example

When the user creates a table, a negative integer is entered for the number of table rows. The

validateTag() function detects the invalid input, displays an alert message, and returns a

false value.

applyTag()

Availability

Dreamweaver MX.

Description

When the user clicks OK, Dreamweaver calls the validateTag() function. If the

validateTag() function returns a true value, Dreamweaver calls this function and passes

the

dom object that represents the current tag (the tag that is being edited). The function reads

the values out of the form elements and writes them into the

dom object.

Arguments

tag

■ The tag argument is the DOM node of the tag being edited.

Returns

Dreamweaver expects nothing.
