 * Hi all,
    I have wordpress plugin with js-file attached for js functions. I want
   to escape possible error of having js functions with the same name as js functions
   pf other developers so I use some prefix like “nsnpas_” in functions name and
   inputs name. This prefix I define as php constant
 *     ```
       define( 'nsnPluginPrefix', 'nsnpas_' );
   
       and use it like :
       <script type="text/javascript" language="JavaScript">
           /*<![CDATA[*/
           ...
           var <?php echo nsnPluginPrefix ?>obj_productsAjaxSearchBox = new <?php echo nsnPluginPrefix ?>productsAjaxSearchBox(  { nsnPluginPrefix : 'nsnpas_', ...   },
               use_in_search_array, autocomplete_save_options_as_array );  // That is object's ref to my js functions
           ...
                   <input value="<?php echo get_search_query() ?>" name="input_<?php echo nsnPluginPrefix ?>search" id="input_<?php echo nsnPluginPrefix ?>search" class=""  placeholder="Type search" />&nbsp;
          ...
   
                   <img src="<?php echo $plugin_url ?>images/arrow-down.png" alt="Open Options" title="<?php echo esc_html__("Open Options") ?> style="cursor: pointer;"  onclick="javascript:<?php echo nsnPluginPrefix ?>obj_productsAjaxSearchBox.openOptions();">  <!-- margin-left: 10px; width: 16px;height: 16px; -->
       ```
   
 * and in my js file ti which I set nsnPluginPrefix as:
 * …
 * > var this_m_nsnPluginPrefix;
   > function nsnpas_productsAjaxSearchBox(Params, use_in_search_array, autocomplete_save_options_as_array){//
   > constructor of backend artist’s editor – set all params from server
   >  selfproductsAjaxSearchBox
   > = this; this_m_nsnPluginPrefix = Params.nsnPluginPrefix; this_plugin_url = 
   > Params.plugin_url; … }
   > nsnpas_productsAjaxSearchBox.prototype.openOptions = function () {
   >  $( “#span_”
   > +this_m_nsnPluginPrefix+”openOptions”).css(“display”,”none”) $( “#span_”+this_m_nsnPluginPrefix
   > +”hideOptions”).css(“display”,”inline”) $( “#div_”+this_m_nsnPluginPrefix+”
   > ajaxSearchOptions”).css(“display”,”inline”) }
 * It works for me. but I have to write function’s object as literal “nsnpas_”. 
   I mean If I need to change nsnPluginPrefix contant, I would have to change “nsnpas_”
   literal by hand in all js file.
    If there is a way to generate this prefix programmatically
   in js file or can this be salved i some different way?
 *  Thanks!
