The Html class contains (mostly static) methods and constants which are useful for the generation of HTML code. The intention of this class is to generate consistent and error-free code.

Hint: There are hangovers in the code which e.g. are from customer projects and which should not be used by Contrexx. They will be removed in a further version.

Note: This documentation refers to version 4 or older. For newer versions of Cloudrexx, please refer to Html.

The following constants should be used everytime the attribute has to be inserted dynamically.

    const ATTRIBUTE_CHECKED = ' checked="checked"';
    const ATTRIBUTE_SELECTED = ' selected="selected"';
    const ATTRIBUTE_DISABLED = ' disabled="disabled"';
    const ATTRIBUTE_READONLY = ' readonly="readonly"';
    const ATTRIBUTE_MULTIPLE = ' multiple="multiple"';

    const CSS_DISPLAY_NONE = 'display:none;';
    const CSS_DISPLAY_INLINE = 'display:inline;';
    const CSS_DISPLAY_BLOCK = 'display:block;';


Example: getInputText(): Generates HTML code for a one line text input field.

The documentation of this and all other methods are visible in the PHPDoc in the code or on the documentation page.
