我有这个:
<!-- <div class="fieldcontain ${hasErrors(bean: azafataInstance, field: 'localidad', 'error')} required" style="margin-left: 10px">-->
<!--<label for="localidad">Localidad</label> -->
<!--<g:if test="${params?.localidad }">-->
<!--<g:select id="localidad" title="${g.message(code: 'infoPersonal.localidad')}" name="localidad" value="${params?.localidad}" from="${[' ',params.localidad]}" noSelection="${['':message(code:'localidadSelect')]}" onClick="this.style.color='black'" onFocus="this.style.color='black'" style="max-width:168px" />-->
<!--</g:if>-->
<!--<g:else>-->
<!--<g:select id="localidad" title="${g.message(code: 'infoPersonal.localidad')}" name="localidad" value="${params?.localidad}" from="${['']}" noSelection="${['':message(code:'localidadSelect')]}" onClick="this.style.color='black'" onFocus="this.style.color='black'" style="max-width:168px" />-->
<!--</g:else>-->
<!--</div>-->
如您所见...注释行。我运行该项目,我得到了:

问题是,显然...
在一个体面的框架中,注释行怎么可能引发异常!
最佳答案
因为<!--
在GSP中不是注释。
如您所见,GSP解析器将HTML样式的注释视为普通内容,从而可以生成包含HTML注释的输出,例如脚本标记内
<script type="text/javascript><!--
js goes here;
//--></script>
或IE conditional comments
<!--[if IE 6]>
<script type="text/javascript" src="${resource(dir:'css', file:'ie6-fixup.js')}"></script>
<![endif]-->
GSP注释的语法是
<%-- this is commented out --%>
GSP解析器将忽略此类注释中的任何内容。
