${var} 在 Select onchange 事件中没有被替换

我在渲染的模板中进行了以下选择，将 i 传递到模型中。正如大多数地方所预期的那样，${i} 被替换为 i 的值。但 ${i} 在 onchange 事件中没有被替换。

因此，

<g:select class='setTagtypeValue-class'
        name='tagtype-${i}-header'
        from="${org.maflt.ibidem.Tagtype.list(sort:'tagtype').groupBy{it.tagtype}.keySet()}"
        value="${setTagtypeValue?.tagtype?.tagtype}"
        noSelection="${['null':'Select One...']}"
        onchange="${remoteFunction(action:'options', update:'tagtype-options-${i}',  
                    params:'\'tagtype=\' + this.value +\'&i=${i}\'' )}" />

呈现为：

<select name="tagtype-0-header" onchange="jQuery.ajax({type:'POST',data:'tagtype=' + this.value +'&amp;i=${i}', url:'/ibidem/metadataSet/options',success:function(data,textStatus){jQuery('#tagtype-options-${i}').html(data);},error:function(XMLHttpRequest,textStatus,errorThrown){}});" class="setTagtypeValue-class" id="tagtype-0-header">
<option value="null">Select One...</option>
<option value="abstract">abstract</option>
. . .
</select>

请注意，例如，名称已设置为“tagtype-0-header”，但在 onchange 中我得到了

data:'tagtype=' + this.value +'&amp;i=${i}'

另请注意，在创建期间使用此模板时，替换发生在客户端，一切都按预期进行。因此，唯一的问题是在编辑期间，在服务器端工作时， ${i} 不会在 onchange 事件中被替换。

有什么想法吗？

I have following select in a template that I render, passing i in the model. ${i} get's replaced with the value of i, as expected in most places. But ${i} is not getting replaced in the onchange event.

So,

<g:select class='setTagtypeValue-class'
        name='tagtype-${i}-header'
        from="${org.maflt.ibidem.Tagtype.list(sort:'tagtype').groupBy{it.tagtype}.keySet()}"
        value="${setTagtypeValue?.tagtype?.tagtype}"
        noSelection="${['null':'Select One...']}"
        onchange="${remoteFunction(action:'options', update:'tagtype-options-${i}',  
                    params:'\'tagtype=\' + this.value +\'&i=${i}\'' )}" />

gets rendered as:

<select name="tagtype-0-header" onchange="jQuery.ajax({type:'POST',data:'tagtype=' + this.value +'&i=${i}', url:'/ibidem/metadataSet/options',success:function(data,textStatus){jQuery('#tagtype-options-${i}').html(data);},error:function(XMLHttpRequest,textStatus,errorThrown){}});" class="setTagtypeValue-class" id="tagtype-0-header">
<option value="null">Select One...</option>
<option value="abstract">abstract</option>
. . .
</select>

Notice that, for example, name has been set to "tagtype-0-header", but in the onchange I'm getting

data:'tagtype=' + this.value +'&i=${i}'

Also note that when this template is used during Create, where the substition happens client side, everything works as expected. So the only problem is that during Edit, working server-side, ${i} isn't getting replaced within the onchange event.

Any ideas?

由于您已经位于 ${} 内部，因此内部 ${} 将被忽略。试试这个：

<g:select class='setTagtypeValue-class'
    name='tagtype-${i}-header'
    from="${org.maflt.ibidem.Tagtype.list(sort:'tagtype').groupBy{it.tagtype}.keySet()}"
    value="${setTagtypeValue?.tagtype?.tagtype}"
    noSelection="${['null':'Select One...']}"
    onchange="${remoteFunction(action:'options', update:'tagtype-options-' + i,  
                params:'\'tagtype=\' + this.value +\'&i=' + i + '\'' )}" />

Since you're already inside of a ${}, the inner ${} is going to be ignored. Try this out:

<g:select class='setTagtypeValue-class'
    name='tagtype-${i}-header'
    from="${org.maflt.ibidem.Tagtype.list(sort:'tagtype').groupBy{it.tagtype}.keySet()}"
    value="${setTagtypeValue?.tagtype?.tagtype}"
    noSelection="${['null':'Select One...']}"
    onchange="${remoteFunction(action:'options', update:'tagtype-options-' + i,  
                params:'\'tagtype=\' + this.value +\'&i=' + i + '\'' )}" />
