Struts的取值与标签

<s:if test="%{false}">
    <div>Will Not Be Executed</div>
</s:if>
<s:elseif test="%{true}">
    <div>Will Be Executed</div>
</s:elseif>
<s:else>
    <div>Will Not Be Executed</div>
</s:else>

再说jstl的if之前我们先看看EL运算符

jstl的if如下:

                            <s:if test="%{list.{content}[2]==入网优先}">
                            <option value="入网优先" selected="selected">入网优先</option>
                            </s:if>
                            <s:else>
                                <option value="入网优先">入网优先</option>
                            </s:else>

                                <s:if test="%{list.{content}[2]==\"上网优先\"}">
                                    <option value="上网优先" selected="selected">上网优先</option>
                                </s:if>
                                <s:else>
                                    <option value="上网优先">上网优先</option>
                                </s:else>
