Struts 2:带点或逗号的双精度值 [英] Struts 2 : double values with point or comma

问题描述

我不能用点插入双精度值的问题(示例2.2)，但是我可以用逗号插入双精度值(示例:2,2).

The problem that I can't insert double values with point (example 2.2), however I can insert them with comma (example : 2,2).

但是当我想使用(JSP和Ajax)编辑它们时，即使我用逗号存储它们，它们也带有(点)出现，所以我必须编辑所有值！

but when I want to edit them using (JSP and Ajax), they appear with (point) even if I stock them with comma, so that I have to edit all values !

场景如下:我想在我的应用程序中编辑一些double值(hibernate和struts2)，我将这些值从action传递给JSP:

the scenario is as follows : I want to edit some double values in my application (hibernate and struts2),i pass the values from action to JSP :

private Service Service;
    private Vehicule v;
    private Map<String, Object> map= new HashMap<>();

    public String query()
    {

            Service = new ServiceImpl();
            v = new Vehicule();
            v= Service.getVehiculeByImmat(field1);
            map.put("date", v.getdate().toString());
    map.put("kilometrage", v.getKilometrage());


    return "success";

    }

然后将它们显示在我的JSP中:

$(document).ready(function(){

      $('#field1').change(function(){


          var selectedValue = $('#field1').val();
            if ($.trim(selectedValue).length > 0) 
             {
          alert(selectedValue);
                $.ajax(
                {
                    type: 'POST', 
                    url  : "<s:url action='query'/>",
                    dataType : 'json',
                    data: { field1: selectedValue},
                    success: function(result){

                        $.each(result, function(key,value)
                        {                      $("#"+key).val(value);
                                    } );

                },

                 });

            }

        }
      );


    });

struts.xml:

struts.xml:

<action name="query" class="action.GestionVehicules" method="query">
          <result name="success" type="json">map</result>
    </action>

我的问题:是否可以将double值插入point?

my question : it's possible to insert the double values with point ?

推荐答案

默认语言环境与客户端上的预期语言环境不同.对于这些语言环境，分数数字格式也有所不同.您可以将操作区域设置为美国区域设置，以在序列化为JSON时使用它.根据该语言环境，它使用小数点分隔小数点，并使用逗号进行分组.

The default locale is different than expected on the client side. Fractional numbers format is also different for those locales. You could set a US locale to the action context to use it when serialized to JSON. According to this locale it uses a dot for fractional part separator and comma for grouping.

ActionContext.getContext().setLocale(Locale.US);  

在返回结果之前执行此操作.

Do it before returning a result.
