表单提交后保留下拉列表值

我有一个表单，用户对一首诗进行从 1 到 3 的评分。我的代码如下：

<select name="rating">
<cfif len(duplicateCheck.score)><option value="#duplicateCheck.score#">You scored:  #duplicateCheck.score#</option>
<cfelse><option value="">&ndash; Rate This Poem &ndash;</option>
</cfif>
<option value="1">1</option>
<option value="2">2</option>
    <option value="3">3</option>
 </select>

如果用户已经对这首诗进行了评分，我会尝试选择他们之前的分数。如果没有，用户可以选择1-3。我该怎么做？

原文

I have a form where a user rates a poem from 1 to 3. My code is as follows:

<select name="rating">
<cfif len(duplicateCheck.score)><option value="#duplicateCheck.score#">You scored:  #duplicateCheck.score#</option>
<cfelse><option value="">– Rate This Poem –</option>
</cfif>
<option value="1">1</option>
<option value="2">2</option>
    <option value="3">3</option>
 </select>

If the user has already rated the poem, I am trying to make their previous score be selected. If not, the user can select 1-3. How should I do this?

取决于您如何存储用户已经对这首诗进行评分的事实。但从高层次来看：

<option value="1"<cfif userHasSelected eq 1> selected="selected"</cfif>>1</option>
<option value="2"<cfif userHasSelected eq 2> selected="selected"</cfif>>2</option>
<option value="3"<cfif userHasSelected eq 3> selected="selected"</cfif>>3</option>

那么，您是否已经掌握了用户是否对这首诗进行了评分？或者这是真正的问题吗？

Depends on how you're storing the fact that the user has already rated the poem. But from a high level:

<option value="1"<cfif userHasSelected eq 1> selected="selected"</cfif>>1</option>
<option value="2"<cfif userHasSelected eq 2> selected="selected"</cfif>>2</option>
<option value="3"<cfif userHasSelected eq 3> selected="selected"</cfif>>3</option>

So, do you already have a handle on whether or not the user has rated the poem? Or is that the actual question?

如果您循环浏览选项列表，您可以动态地执行此操作。

<cfloop from="1" to="3" index="thisOption">
   <option value="#thisOption#" <cfif userHasSelected eq thisOption> selected="selected"   
   </cfif>>#thisOption#</option>
</cfloop>

或者您可以移动代码以从选项 html 中选择下拉列表，这是我更喜欢的。

<cfloop from="1" to="3" index="thisOption">
   <cfset variables.selected = userHasSelected eq thisOption? 'selected' : '' />
   <option value="#thisOption#" #selected#>#thisOption#</option>
</cfloop>

If you loop through your list of options you could do this dynamically.

<cfloop from="1" to="3" index="thisOption">
   <option value="#thisOption#" <cfif userHasSelected eq thisOption> selected="selected"   
   </cfif>>#thisOption#</option>
</cfloop>

Or you can move the code to select the drop down out of the option html, which i prefer.

<cfloop from="1" to="3" index="thisOption">
   <cfset variables.selected = userHasSelected eq thisOption? 'selected' : '' />
   <option value="#thisOption#" #selected#>#thisOption#</option>
</cfloop>
