 * Dear WordPress community,
 * I am using a WordPress plugin which is called “Advanced Custom fields” and I 
   am very happy with its ease of use and functionalities.
 * What I am looking forward to achieve is to add a specific hook or functionality
   to one of my fields to open a popup field once clicked.
 * The code I have created and that I would like to run for the popup would be the
   following:
 *     ```
       <script language="javascript" type="text/javascript">
           function popup(url)
           {
            var width  = 480;
            var height = 500;
            var left   = (screen.width  - width)/2;
            var top    = (screen.height - height)/2;
            var params = 'width='+width+', height='+height;
            params += ', top='+top+', left='+left;
            params += ', directories=no';
            params += ', location=no';
            params += ', menubar=no';
            params += ', resizable=no';
            params += ', scrollbars=no';
            params += ', status=no';
            params += ', toolbar=no';
            newwin=window.open(url,'windowname5', params);
            if (window.focus) {newwin.focus()}
            return false;
           }
           </script>
   
           <input type="text" name="field" id="field"onclick="javascript:popup('https://myurl', '200', '200', '510', '440');return false;">
       ```
   
 * The code of my field looks as follows:
 * `<div id="acf-custom_field" class="field field-text"><p class="label"><label 
   for="fields[field_5007b7f298fd6]">Custom field</label></p><input type="text" 
   value="" id="fields[field_5007b7f298fd6]" class="text" name="fields[field_5007b7f298fd6]"
   ></div>`
 * Is there an easy way (for example by adding something in theme-functions) to 
   add a on click event to this specific item?
 * Some expert advise would be highly appreciated.
 * Thank you very much,
    Patrick
