|
|
// This plugin has three modes:
|
|
//
|
|
// * blockNodeForEnter=BR
|
|
// * blockNodeForEnter=DIV
|
|
// * blockNodeForEnter=P
|
|
//
|
|
// In blockNodeForEnter=P, the ENTER key starts a new
|
|
// paragraph, and shift-ENTER starts a new line in the current paragraph.
|
|
// For example, the input:
|
|
//
|
|
// | first paragraph <shift-ENTER>
|
|
// | second line of first paragraph <ENTER>
|
|
// | second paragraph
|
|
//
|
|
// will generate:
|
|
//
|
|
// | <p>
|
|
// | first paragraph
|
|
// | <br/>
|
|
// | second line of first paragraph
|
|
// | </p>
|
|
// | <p>
|
|
// | second paragraph
|
|
// | </p>
|
|
//
|
|
// In BR and DIV mode, the ENTER key conceptually goes to a new line in the
|
|
// current paragraph, and users conceptually create a new paragraph by pressing ENTER twice.
|
|
// For example, if the user enters text into an editor like this:
|
|
//
|
|
// | one <ENTER>
|
|
// | two <ENTER>
|
|
// | three <ENTER>
|
|
// | <ENTER>
|
|
// | four <ENTER>
|
|
// | five <ENTER>
|
|
// | six <ENTER>
|
|
//
|
|
// It will appear on the screen as two 'paragraphs' of three lines each. Markupwise, this generates:
|
|
//
|
|
// BR:
|
|
// | one<br/>
|
|
// | two<br/>
|
|
// | three<br/>
|
|
// | <br/>
|
|
// | four<br/>
|
|
// | five<br/>
|
|
// | six<br/>
|
|
//
|
|
// DIV:
|
|
// | <div>one</div>
|
|
// | <div>two</div>
|
|
// | <div>three</div>
|
|
// | <div> </div>

// | <div>four</div>

// | <div>five</div>
