The type read-only property of the Selection interface returns a DOMString describing the type of the current selection.

语法

value = sel.type

Value

A DOMString describing the type of the current selection. Possible values are:

  • None: 当前没有选择。
  • Caret: 选区已折叠（即 光标在字符之间，并未处于选中状态）。
  • Range: 选择的是一个范围。

例子

In this example, the event handler will fire each time a new selection is made. console.log(selection.type) will return Caret or Range depending on whether the caret is placed at a single point in the text, or a range has been selected.

var selection;

document.onselectionchange = function() {
  console.log('New selection made');
  selection = document.getSelection();
  console.log(selection.type);
};
