用javascript数组填充struts2选择标签 [英] Fill struts2 select tag with javascript array

问题描述

是否有可能在加载时使用javascript数组填充Struts 2选择标签？

我有一个代码

 < s：select id =attrStpSelname =attrStpSelheaderKey = -  1
 headerValue =Selectlist =$ {attributeActions}
 labelposition =leftonchange =displaySelectAction（）
 cssStyle =width：300px; /> 
  

这是页面中的脚本。

< pre class =lang-jsp prettyprint-override> < script type =text / javascript>
$（document）.ready（function（）{
var attributeActions = ['Add'，'Update'，'Search'];
}）;
< / script>


由于它是一个硬编码值，我不希望它们从行为中填充。使用上面的代码，javascript变量 attributeActions 没有被拾取。

将静态列表填充到Struts 2 select标签中的理想方式是什么？

解决方案

您可以使用＃{} 创建一个内联列表：

< s：select name =attrStpSel
headerKey =-1
headerValue =Select
list =＃{'Add'，'Update'，'Search'}/>


您也可以使用相同的表示法创建内嵌地图：

 < s：select name =attrStpSel
 headerKey =-1
 headerValue =Select 
 list =＃{'0'：'添加'，'1'：'更新'，'2'：'搜索'}/> 
  

Is it possible to fill the Struts 2 select tag with javascript array on load?

I have a code

<s:select id="attrStpSel" name="attrStpSel" headerKey="-1"
          headerValue="Select" list="${attributeActions}"
          labelposition="left" onchange="displaySelectAction()"
          cssStyle="width: 300px;" />

This is the script in the page.

<script type="text/javascript">
    $(document).ready(function() {
        var attributeActions = [ 'Add', 'Update', 'Search' ];
    });
</script>

Since it is a hard coded values, I don't want them to be populated from action. with the above code the javascript variable attributeActions is not being picked up.

What should be the ideal way to populate the static list into the Struts 2 select tag?

解决方案

You can create an inline list with #{}:

<s:select name = "attrStpSel" 
     headerKey = "-1"
   headerValue = "Select" 
          list = "#{'Add','Update','Search'}" />

You can also create an inline map with the same notation:

<s:select name = "attrStpSel" 
     headerKey = "-1"
   headerValue = "Select" 
          list = "#{'0':'Add' , '1':'Update' , '2':'Search'}" />
