现在，你可能会想：
<input type="submit" value="Subscribe!" th:attr="value=#{subscribe.submit}"/>上面代码是一段相当难看的标记。在 th:attr 属性值中指定赋值可能非常实用，但如果您必须一直这样做，那么这不是创建模板的最好方法。
Thymeleaf 同意您的观点，这就是为什么模板中很少使用 th:attr。通常，您将使用其他 th:* 属性，其任务是设置特定的标记属性（而不仅仅是 th:attr 之类的任何属性）。
例如，要设置 value 属性，请使用 th:value：
<input type="submit" value="Subscribe!" th:value="#{subscribe.submit}"/>这看起来好多了！让我们尝试对表单标记中的 action 属性执行同样的操作：
<form action="subscribe.html" th:action="@{/subscribe}">你还记得我们之前在 home.html 中放的那些 th:href 属性吗？它们是完全相同的属性：
<li><a href="product/list.html" th:href="@{/product/list}">Product List</a></li>像这样的属性有很多，每个属性都针对特定的 HTML5 属性。如下：
th:abbr th:accept th:accept-charset th:accesskey th:action th:align th:alt th:archive th:audio th:autocomplete th:axis th:background th:bgcolor th:border th:cellpadding th:cellspacing th:challenge th:charset th:cite th:class th:classid th:codebase th:codetype th:cols th:colspan th:compact th:content th:contenteditable th:contextmenu th:data th:datetime th:dir th:draggable th:dropzone th:enctype th:for th:form th:formaction th:formenctype th:formmethod th:formtarget th:fragment th:frame th:frameborder th:headers th:height th:high th:href th:hreflang th:hspace th:http-equiv th:icon th:id th:inline th:keytype th:kind th:label th:lang th:list th:longdesc th:low th:manifest th:marginheight th:marginwidth th:max th:maxlength th:media th:method th:min th:name th:onabort th:onafterprint th:onbeforeprint th:onbeforeunload th:onblur th:oncanplay th:oncanplaythrough th:onchange th:onclick th:oncontextmenu th:ondblclick th:ondrag th:ondragend th:ondragenter th:ondragleave th:ondragover th:ondragstart th:ondrop th:ondurationchange th:onemptied th:onended th:onerror th:onfocus th:onformchange th:onforminput th:onhashchange th:oninput th:oninvalid th:onkeydown th:onkeypress th:onkeyup th:onload th:onloadeddata th:onloadedmetadata th:onloadstart th:onmessage th:onmousedown th:onmousemove th:onmouseout th:onmouseover th:onmouseup th:onmousewheel th:onoffline th:ononline th:onpause th:onplay th:onplaying th:onpopstate th:onprogress th:onratechange th:onreadystatechange th:onredo th:onreset th:onresize th:onscroll th:onseeked th:onseeking th:onselect th:onshow th:onstalled th:onstorage th:onsubmit th:onsuspend th:ontimeupdate th:onundo th:onunload th:onvolumechange th:onwaiting th:optimum th:pattern th:placeholder th:poster th:preload th:radiogroup th:rel th:rev th:rows th:rowspan th:rules th:sandbox th:scheme th:scope th:scrolling th:size th:sizes th:span th:spellcheck th:src th:srclang th:standby th:start th:step th:style th:summary th:tabindex th:target th:title th:type th:usemap th:value th:valuetype th:vspace th:width th:wrap th:xmlbase th:xmllang th:xmlspace
