这段js使用的是什么语法？

<script type="text/plain" id="endOfFloor">

<div class="commentBox clearfix"> <#=innerFloor#> <div class="floo优艾设计网_Photoshop问答r-content" data-floornum="<#=seq#>"> <div class="commentInfo"> <span class="floorCount right"><#=seq#></span> <span class="author"><#=author#></span> </div> <p class="content"><#=content#></p> <# if (typeof tieOperation != "undefined"){ #><div class="tieOperations clearfix"><#=tieOperation#></div><# } #> </div> </div>

</script>
