Struts渲染我的表错误 [英] Struts rendering my table wrong

问题描述

 < table class =ListingTable> 
有人可以告诉我，为什么我的表格显示错误吗？ ; 
< thead> 
< tr> 
< th style =border-left-style：hidden;> ProjectName< / th> 
< th> CustomerID< / th> 
 Leader< / th> 
 th DeadLine< / th> 
< th>状态< / th> 
< th style =border-right-style：hidden;>< / th> 
< / tr> 
< / thead> 
< tbody> 
< s：iterator value =projectMapsstatus =Statusindex> 
< tr> 
< td>< s：property value =Name/>< / td> 
< td>< s：property value =CustomerID/>< / td> 
< td>< s：property value =Leader/>< / td> 
< td>< s：property value =DeadLine/>< / td> 
< td>< s：属性值=状态/>< / td> 
< td> 
< form action =Details.action> 
 < s：submit type =submitid =％{Index}value =Details
 method =executestyle =height：20px; /> 
< / form> 
< / td> 
< / tr> 
< / s：iterator> 
< / tbody> 
< / table> 
  

它应该是这样的：

但看起来像这样：

它必须在< form> < / form> ，因为如果我将它注释掉并用一个Button替换它，我会从第一张图片中得到结果。

它会为每个按钮创建一个新的< tr> 额外值，这是我不理解的！

解决方案使用简单主题来防止框架生成额外的< tr> ：
$ b

 < s：submit type =submit
 id =％ {Index}
 value =Details
 method =execute
 cssStyle =height：20px; 
 theme =简单/> 
  

另外 style 应该是 cssStyle 在Struts标签中。

最后，避免使用DMI（动态方法调用， method = 部分），因为它非常不鼓励。如果方法是 execute（），那么甚至不需要它是默认的。

Can someone Tell me, why my Table is rendered the wrong way?

<table class="ListingTable">
        <thead>
            <tr>
                <th style="border-left-style: hidden;">ProjectName</th>
                <th>CustomerID</th>
                <th>Leader</th>
                <th>DeadLine</th>
                <th>Status</th>
                <th style="border-right-style: hidden;"></th>
            </tr>
        </thead>
        <tbody>
            <s:iterator value="projectMaps" status="Statusindex">
                <tr>
                    <td><s:property value="Name" /></td>
                    <td><s:property value="CustomerID" /></td>
                    <td><s:property value="Leader" /></td>
                    <td><s:property value="DeadLine" /></td>
                    <td><s:property value="Status" /></td>
                    <td>
                        <form action="Details.action">
                            <s:hidden id="statusid" name="statusid" value="%{Index}" />
                            <s:submit type="submit" id="%{Index}" value="Details"
                                method="execute" style="height:20px;" />
                        </form>
                    </td>
                </tr>
            </s:iterator>
        </tbody>
    </table>

It should look like this:

But it looks like this:

It must be within the <form> </form> because if I comment it out and replace it with just a Button, I get the result from the first picture.

It creates a new <tr> extra for each button, which I don't understand!

解决方案

Use the simple theme to prevent the framework from generating the extra <tr>:

<s:submit type = "submit" 
            id = "%{Index}" 
         value = "Details"
        method = "execute" 
      cssStyle = "height:20px;" 
         theme = "simple" />

Also style should be cssStyle in Struts Tags.

And finally, avoid using DMI (Dynamic Method Invocation, the method="" part) because it is highly discouraged. It is not even needed if the method is execute(), the default one.
