Struts：选择HTML选项？ [英] Struts: HTML Option Selected?

问题描述

在struts中，似乎没有选择选项。 HTML选项标签有一个选定的属性，您可以这样做：

 < option selected =selected> Some Option< ; /选项> 
  

并且该选项将被自动选择。有没有办法在struts中做到这一点？看来，在struts中，它随机自动选择一个我的选项，我不明白的原因，我想能够指定哪个选项应该自动选择。

< html：select> 标记中完成的，而不是在 < html：option> 类似于纯HTML 选项。

值 nofollow> < html：select> 标记用于比较每个< html：option> 值并在找到匹配项时将其标记为选中。

In struts, it seems there is no "selected" option. The HTML option tag has a selected attribute such that you can do:

<option selected="selected">Some Option</option>

and that option will be automatically selected. Is there a way to do this in struts? It seems that in struts, its randomly auto-selected one my options for a reason I don't understand and I would like to be able to specify which option should be auto selected.

解决方案

In Struts this is done in the <html:select> tag and not in the <html:option> like for the the case of plain HTML option.

The value attribute of the <html:select> tag is used to compare against each <html:option> value and marking it as selected if a match is found.
