JavaScript的Struts2参数 [英] Struts2 parameter to javascript

问题描述

我有一个带有字段的struts2动作:private Long omradeId; 该字段有一个吸气剂.

I have a struts2 action with a field: private Long omradeId; The field has a getter.

动作被发送到一个jsp，在该jsp中，我可以使用<s:property>标签访问该字段.很好.

The action is sent to a jsp and within that jsp i can access the field using <s:property>tag. Thats all good.

现在，我在jsp中也有一个部分，我在其中定义了<script>.在该脚本中，我想创建一个变量，该变量将使用上述struts2字段作为值来构建URL.

Now i also have within the jsp a section where i define a <script>. Within that script i would like to create a variable that will build a url with the above mentioned struts2 field as a value.

<script type="text/javascript">
var url = "/path/to/action?parameter1=";
</script>

如何将omradeId的值放在等号(=)后面?我尝试使用<s:property>，但是没有用. 有什么建议吗?

How can i put the value of omradeId after the equals (=) sign? I tried using <s:property>but that did not work. Any suggestions?

推荐答案

这应该有效:

<script type="text/javascript">
var url = "/path/to/action?parameter1=<s:property value="omradeId">";
</script>

如果不是，则应检查该值是否不为null并在操作类中成功设置该值.

If not you should check if the value is not null and value is successfully set in your action class.
