如果街道地址整个 div block 是指具有类 pc_flex_form_line_container 的第二个元素。你可以这样做:

$('.pc_flex_form_line_container:eq(1)').hide(); 

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="pc_flex_form_line_container">
       <div class="pc_flex_form_label_item">Company
       </div>
       <div class="pc_flex_form_required_flag_item"><img src="/corestrengths/s.gif" class="requiredFieldMarker" />
       </div>
       <div class="pc_flex_form_field_item"><input id="siteQuickEventRegPage:SiteTemplate:evtRegForm:attendeeInfoForms:2:mailingcompany" type="text" name="siteQuickEventRegPage:SiteTemplate:evtRegForm:attendeeInfoForms:2:mailingcompany" class="pc_medium_input_field" /> 
       </div>
   </div>



   <div class="pc_flex_form_line_container">
       <div class="pc_flex_form_label_item">Street Address
       </div>
       <div class="pc_flex_form_required_flag_item"><img src="/corestrengths/s.gif" class="requiredFieldMarker" />
       </div>
       <div class="pc_flex_form_field_item"><input id="siteQuickEventRegPage:SiteTemplate:evtRegForm:attendeeInfoForms:2:mailingstreet" type="text" name="siteQuickEventRegPage:SiteTemplate:evtRegForm:attendeeInfoForms:2:mailingstreet" class="pc_long_input_field" />
       </div>
   </div>
