从Smarty PHP循环(JQuery)中的select中获取选项值

So I need to append and un-append divs which contain the values of whichever option was selected, problem is that the method of displaying the select values in the first place is via. a for-each loop using Smarty PHP templates, and I am unable to find any documentation on how it can be achieved using this.

What I've tried: as you will see below I've tried creating a JavaScript variable inside the template file, but it only ever returns the value of the first option selected. I cannot figure out why I am only ever getting the first value taken from the loop.

For example, if I have two items in a select 'A' and 'B', when selecting the value option, I will always just receive 'A' back as the value.

Smarty Template Code:

<select class="my_select" name="vlans_{$NetworkDTO->id}[]">
    {foreach from=$arrNetworkDTO item=NetworkDTO name=arr}
    <option class="addOvmCardList" id="addNameDisk{$strIdTpl}" value="{$NetworkDTO->name|escape}">{$NetworkDTO->name}</option>
    {/foreach}
</select>

JQuery Code:

$('a.addListOVM').click(function(){

    $(".my_select").change(function() {

        $('.addCardOVM').append(
              '<div class="divform"><label>' + $(this).val() + '</label>' +
              '<a href="">-</a></div>'
                );              
    });                             

});

Any help is appreciated.

所以我需要追加和取消追加包含选择了哪个选项值的div,问题是 首先显示选择值的方法是via。 使用Smarty PHP模板的for-each循环,我无法找到有关如何使用它实现它的任何文档。</ p>

我尝试过的方法:</ strong >正如您将在下面看到的,我尝试在模板文件中创建一个JavaScript变量,但它只返回所选第一个选项的值。 我无法弄清楚为什么我只得到从循环中取得的第一个值。</ p>

例如,如果我在选择'A'和'B'中有两个项目,那么在选择时 值选项,我将始终只接收'A'作为值。</ p>

Smarty模板代码:</ strong> </ p>

  &lt; select class =“my_select”name =“vlans _ {$ NetworkDTO-&gt; id} []”&gt; 
 {foreach from = $ arrNetworkDTO item = NetworkDTO name = arr} 
&lt; option class =  “addOvmCardList”id =“addNameDisk {$ strIdTpl}”value =“{$ NetworkDTO-&gt; name | escape}”&gt; {$ NetworkDTO-&gt; name}&lt; / option&gt; 
 {/ foreach} 
&lt;  / select&gt; 
 </ code> </ pre> 
 
 

JQuery代码:</ strong> </ p>

  $('a.addListOVM  ')。click(function(){
 
 $(“。my_select”)。change(function(){
 
 $('。addCardOVM')。append(
'&lt; div class =“  divform“&gt;&lt; label&gt;'+ $(this).val()+'&lt; / label&gt;'+ 
'&lt; a href =”“&gt;  - &lt; / a&gt;&lt; / div&gt;  '
); 
});  
 
}); 
 </ code> </ pre> 
 
 

感谢任何帮助。</ p> </ div>
