SummaryEdit

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". In IE6-10, the value is capitalized.

SyntaxEdit

var mode = document.designMode;
document.designMode = "on";
