Struts2 Tag 标签

struts2 OGNL 中的#、%等符号的区别：
Apache Struts 2 Documentation -> OGNL:
http://struts.apache.org/2.2.3/docs/ognl.html
Apache Struts 2 Documentation -> Tag Syntax:
http://struts.apache.org/2.2.3/docs/tag-syntax.html
Struts 2: %{} or # :

Setting the value in <s:textfield from request scope:
http://www.coderanch.com/t/440061/Struts/Setting-value-textfield-request-scope

引用

%{} is the OGNL escape. The # means it's an action context "scope" variable, not on the stack.
Again--there's zero reason to do it like this, and at least a couple reasons not to.

Js中取struts2标签s:autocompleter的值（版本：2.0.11.1）：

<s:autocompleter theme="simple" id="steelgradeIdjh" name="qm.steelgradeId" list="steelgradesNameList" cssClass="textinput" forceValidOption="true" cssStyle="width:80" />

var obj = dojo.widget.byId("steelgradeIdjh");
alert(obj.getValue());

不要在普通html标签中嵌套struts2 ognl表达式。如这样的写法是错误的：

<input  type="text"  name="fidsDispTempdataList[%{#stas.index}].pages" id="fidsDispTempdataList[%{#stas.index}].pages" size="4">

正确的应该是：

<s:textfield id="fidsDispTempdataList[%{#stas.index}].pages" name="fidsDispTempdataList[%{#stas.index}].pages" theme="simple" value=""></s:textfield>

但是可以在普通html标签中嵌套struts2标签，如：

<input  type="text" name="fidsDispTemplate.code" id="fidsDispTemplate.code" value="<s:property value="fidsDispTemplate.code"/>" />
