  4. Document.designMode

在此页

document.designMode controls whether the entire document is editable. Valid values are "on" and "off" . According to the specification, this property is meant to default to "off" . Firefox follows this standard. The earlier versions of Chrome and IE default to "inherit" . Starting in Chrome 43, the default is "off" and "inherit" is no longer supported. In IE6-10, the value is capitalized.

句法
