Parameters

Table 41-28 GET_ELEMENT_ATTRIBUTES Function Parameters

Parameters	Description
`p_item`	This is the p_item parameter of your plug-in function.
`p_name`	This is the value which has been return by apex_plugin.get_input_name_or_page_item
`p_default_class`	Default CSS class which which should be contained in the result string.
`p_add_id`	If set to TRUE then the id attribute is also contained in the result string.
`p_add_labelled_by`	Returns some of the general attributes of an HTML element (for example, the ID, name, required, placeholder, aria-error-attributes, class) which should be used if an HTML input, select, or textarea tag is generated to get a consistent set of attributes.Set to FALSE if you render a HTML input element like input, select, or textarea which does not require specifying the aria-labelledby attribute because the label's `for` attribute works for those HTML input elements. Set it to TRUE for all 'non-standard form element widgets (that is, those using div, span, and so on.) which do allow focus to make them accessible to screen readers. Note: Inclusion of aria-labelled by is also dependent on the item plug-in having Standard Form Element set to No and that there is a `#LABEL_ID#` substitution defined in the item's corresponding label template.
`p_aria_describedby_id`	Pass additional IDs here that you would like `get_element_attributes` to include in the value it renders for the `'aria-describedby'` attribute on the form element. This can be useful if you would like to convey additional information to users of Assistive Technology, when they are focused on the form field.

Example

This example emits an INPUT tag of type text which uses apex_plugin_util.get_element_attributes to automatically include the most common attributes.

sys.htp.prn (
        '<input type="text" ' ||
        apex_plugin_util.get_element_attributes(p_item, l_name, 'text_field') ||
        'value="'||l_escaped_value||'" '||
        'size="'||p_item.element_width||'" '||
        'maxlength="'||p_item.element_max_length||'" '||
        ' />');
