This function returns the AJAX identifier used to call the AJAX callback function defined for the plug-in.
Note:
This function only works in the context of a plug-in rendering function call and only if the plug-in has defined an AJAX function callback in the plug-in definition.APEX_PLUGIN.GET_AJAX_IDENTIFIER RETURN VARCHAR2;
None.
This is an example of a dynamic action plug-in rendering function that supports an AJAX callback.
function render_set_value (
p_dynamic_action in apex_plugin.t_dynamic_action )
return apex_plugin.t_dynamic_action_render_result
is
l_result apex_plugin.t_dynamic_action_render_result;
begin
l_result.javascript_function := 'com_oracle_apex_set_value';
l_result.ajax_identifier := wwv_flow_plugin.get_ajax_identifier;
return l_result;
end;
Use this function when you want to render an HTML input element in the rendering function of an item type plug-in.For the HTML input element, for example, <input type="text" id="P1_TEST" name="xxx">, you have to provide a value for the name attribute so that Oracle Application Express can map the submitted value to the actual page item in session state. This function returns the mapping name for your page item. If the HTML input element has multiple values, such as a select list with multiple="multiple", then set p_is_multi_value to true.
Note:
This function is only useful when called in the rendering function of an item type plug-in.
APEX_PLUGIN.GET_INPUT_NAME_FOR_PAGE_ITEM (
p_is_multi_value IN BOOLEAN)
RETURN VARCHAR2;
Table 18-1 describes the parameters available in the GET_INPUT_NAME_FOR_PAGE_ITEM function.

The following example outputs the necessary HTML code to render a text field where the value gets stored in session state when the page is submitted.
sys.htp.prn (
'<input type="text" id="'||p_item.name||'" '||
'name="'" '||
'value="'||sys.htf.escape_sc(p_value)||'" '||
'size="'||p_item.element_width||'" '||
'maxlength="'||p_item.element_max_length||'" '||
coalesce(p_item.element_attributes, 'class="text_field"')||' />' );
