space_userabout.htm里也有，和上面的代码形式相同。{lang }有区别，取消收听{lang follow_del}，收听{lang follow_add}TA。space_card也有这个东西，但是代码稍有不同，不同uid有区分，如下。<!--{if helper_access::check_module('follow')}--><a href="home.php?mod=spacecp&ac=follow&op={if !empty($follow)}del{else}add{/if}&hash={FORMHASH}&fuid=$space[uid]" id="card_followmod_$space[uid]" onclick="showWindow(this.id, this.href, 'get', 0)" class="xi2"><!--{if !empty($follow)}-->{lang follow_del}<!--{else}-->{lang follow_add}TA<!--{/if}--></a><!--{/if}--><script type="text/javascript">        function succeedhandle_card_followmod_$space[uid](url, msg, values) {          var linkObj = $('card_followmod_'+values['fuid']);          if(linkObj) {            if(values['type'] == 'add') {              linkObj.innerHTML = '{lang follow_del}';              linkObj.href = 'home.php?mod=spacecp&ac=follow&op=del&fuid='+values['fuid'];            } else if(values['type'] == 'del') {              linkObj.innerHTML = '{lang follow_add}TA';              linkObj.href = 'home.php?mod=spacecp&ac=follow&op=add&hash={FORMHASH}&fuid='+values['fuid'];            }          }        }      </script>
