DomHelper element specification object

A specification object is used when creating elements. Attributes of this object + * <p><b><u>DomHelper element specification object</u></b></p> + * <p>A specification object is used when creating elements. Attributes of this object * are assumed to be element attributes, except for 4 special attributes: - *

    - *
  • tag :

  • children : or cn
    An array of the + * <div class="mdetail-params"><ul> + * <li><b><tt>tag</tt></b> : <div class="sub-desc">The tag name of the element</div></li> + * <li><b><tt>children</tt></b> : or <tt>cn</tt><div class="sub-desc">An array of the * same kind of element definition objects to be created and appended. These can be nested - * as deep as you want.
  • - *
  • cls :
    The class attribute of the element. - * This will end up being either the "class" attribute on a HTML fragment or className - * for a DOM node, depending on whether DomHelper is using fragments or DOM.

Templating

Performance Boost

- *

DomHelper will transparently create HTML fragments when it can. Using HTML fragments instead - * of DOM can significantly boost performance.

- *

Element creation specification parameters may also be strings. If {@link #useDom} is false, - * then the string is used as innerHTML. If {@link #useDom} is true, a string specification - * results in the creation of a text node. Usage:

- *

-Ext.DomHelper.useDom = true; // force it to use DOM; reduces performance
