Im trying to get array[0] as value for the 'attroption' and array[1] as value for 'attrweight' in the code below. How can I do this? Or is there any other way to set this value? 

<div style="visibility: hidden" t-esc="value_id.name" id="attributename"/>                                    
<div style="visibility: hidden" id="attributeextraweight"/>                                    
<script type="text/javascript">                                        
  var input = $("attributename").text();
                                        
  var array = input.split('+');

                                        
  $("attributename").html(array[0]);
                                       
  $("attributeextraweight").html(array[1]);
                                    
</script>                                    
<t t-set="attroption" t-value=""/>                                    
<t t-set="extraweight" t-value="attrweight"/>
