title="Edit this page on GitHub">Edit on GitHub</a> + <h1 id="alt-syntax">Alt Syntax</h1> + +<p>The <em>altSyntax</em> is an option that can be defined in <code class="highlighter-rouge">struts.xml</code>. By default it is set to true and it is <strong>strongly</strong> +recommend you do not change that unless you are upgrading from WebWork 2.1.7 or previous versions.</p> + +<blockquote> + <p>You can also turn on the altSyntax on a per-page basis by using the <em>set</em> tag. Simply set the name <em>useAltSyntax</em><br /> +to the value <em>true</em> . From this point on, all tags will use the altSyntax for the rest of the request.</p> +</blockquote> + +<p>The altSyntax changes the behavior of how tags are interpreted. Instead of evaluating each tag parameter against +the value stack and needing single quotes to mark string literals, only marked expressions are evaluated.</p> + +<p>Example:</p> + +<p>the following code uses the <a href="tag-syntax.html">Tag Syntax</a>:</p> + +<pre><code class="language-jsp"><s:iterator value="cart.items"> + ... + <s:textfield label="'Cart item No.' + #rowstatus.index + ' note'" + name="'cart.items[' + #rowstatus.index + '].note'" + value="note" /> +</s:iterator> +</code></pre> + +<p>this is somewhat counter intuitive to normal HTML tag behaviour, and you get loads of single quotes. Now the same example +in altSyntax:</p> + +<pre><code class="language-jsp"><s:iterator value="cart.items"> + ... + <s:textfield label="Cart item No. %{#rowstatus.index} note" + name="cart.items[%{#rowstatus.index}].note" + value="%{note}" /> +</s:iterator> +</code></pre> + +<p>Only expressions enclosed with <code class="highlighter-rouge">%{}</code> are evaluated. The code is shorter and clearer, very similar to JSTL EL usage. +Quoting problems, eg. with javascript function calls, are avoided.</p> + +<p>In order to fully understand why this option exists and what the differences are, it is best to get a bit of history +about WebWork.</p> + +<blockquote> + <p>If you are <em>not</em> upgrading from WebWork 2.1.7 or previous versions and you donât care about the history of WebWorkâs +evolution, you can skip this section. See the <a href="tag-syntax.html">Tag Syntax</a> section for more information +on the standard tag syntax support</p> +</blockquote> + +<h2 id="history">History</h2> + +<p>In WebWork 2.1.4, the altSyntax option was introduced. The book, WebWork in Action, while based around WebWork 2.1.7, +was entirely written with the assumption that the altSyntax was enabled. As of WebWork 2.2, the altSyntax is turned +on by default and eventually the old syntax will no longer be supported and will be removed from the code.</p> + + </section> +</article> + + +<footer class="container"> + <div class="col-md-12"> + Copyright © 2000-2016 <a href="http://www.apache.org/";>The Apache Software Foundation </a>. + All Rights Reserved. + </div> + <div class="col-md-12"> + Apache Struts, Struts, Apache, the Apache feather logo, and the Apache Struts project logos are + trademarks of The Apache Software Foundation. + </div> + <div class="col-md-12">Logo and website design donated by <a href="https://softwaremill.com/";>SoftwareMill</a>.</div> +</footer> + +<script>!function (d, s, id) { + var js, fjs = d.getElementsByTagName(s)[0]; + if (!d.getElementById(id)) { + js = d.createElement(s); + js.id = id; + js.src = "//platform.twitter.com/widgets.js"; + fjs.parentNode.insertBefore(js, fjs); + } +}(document, "script", "twitter-wjs");</script> +<script src="https://apis.google.com/js/platform.js"; async="async" defer="defer"></script> + +<div id="fb-root"></div> + +<script>(function (d, s, id) { + var js, fjs = d.getElementsByTagName(s)[0]; + if (d.getElementById(id)) return; + js = d.createElement(s); + js.id = id; + js.src = "//connect.facebook.net/en_GB/all.js#xfbml=1"; + fjs.parentNode.insertBefore(js, fjs); +}(document, 'script', 'facebook-jssdk'));</script> + + +<script> +$(function() { + return $("h2, h3, h4, h5, h6").each(function(i, el) { + var $el, id; + $el = $(el); + id = $el.attr('id'); + if (id) { + $el.removeAttr('id'); + return $el.before($("<a />").addClass('anchor').attr('name', id)); + } + }); +}); +</script> + +</body> +</html> http://git-wip-us.apache.org/repos/asf/struts-site/blob/596de5fd/content/tag-developers/index.html ---------------------------------------------------------------------- diff --git a/content/tag-developers/index.html b/content/tag-developers/index.html index ee6e4bc..d276d09 100644 --- a/content/tag-developers/index.html +++ b/content/tag-developers/index.html @@ -151,7 +151,7 @@ </ul> </li> <li><a href="tag-syntax.html">Tag Syntax</a></li> - <li><em>Alt Syntax</em></li> + <li><a href="alt-syntax.html">Alt Syntax</a></li> <li><a href="jsp.html">JSP</a> <ul> <li><a href="jsp-tags.html">specific tags</a></li>
