hasLayout Property

---

Retrieves a value that indicates whether the object has layout.

Syntax

HTML	N/A
Scripting	[ sHasLayout = ] object.currentStyle.hasLayout

Possible Values

sHasLayout

Boolean that receives one of the following values. false Default. Object does not have layout. true Object has layout.

The property is read-only. The property has a default value of false. The Microsoft Cascading Style Sheets (CSS) extension is not inherited.

Remarks

The following table shows Cascading Style Sheets (CSS) properties and corresponding values that, if set, cause an element to have layout.

CSS property	Value
display	inline-block
height	any value
float	left or right
position	absolute
width	any value
writing-mode	tb-rl
zoom	any value

As of Microsoft® Internet Explorer 6, when the !DOCTYPE declaration specifies strict standards compliance, inline elements will ignore the width and height properties, and setting the width and height properties will not cause the element to have layout.

Setting the contentEditable property to true will cause an element to have layout.

BODY, FIELDSET, IMG, INPUT, TABLE and TD elements always have layout.

 

当hasLayout为false的元素中包含了hasLayout为true的元素时，该子元素在应 用position类型的样式时将会遇到兼容问题。

 

当 hasLayout为false的元素应用position类型的样式时，将会遇到兼容问题。
