功能描述：行政区域国家、省、市、区四级联动
实现步骤:
1、创建行政区域实体，用来记录行政区域信息,如下图：
2、打开行政区域实体查找视图,增加查找列"上级区域id",如下图：
3、在上级区域属性的onchange事件中加入以下js代码：
var lookupItem = new Array;
lookupItem = crmForm.all.new_parentregion.DataValue;
if (IsNull(lookupItem) == false)
{
crmForm.all.new_parentregionid.DataValue = lookupItem[0].id;
}
else
{
crmForm.all.new_parentregionid.DataValue = "{00000000-0000-0000-0000-000000000000}";
}
4、客户跟行政区域之间创建4个1:N的关系，分别为国家、省、市、区，如下图：
5、在客户的onload事件中加入以下js代码：
crmForm.all.new_country.additionalparams = 'search=' + encodeURIComponent("{9C534EEA-FC73-DD11-A8D3-001676D4971B}");
var lookupItem = new Array;
lookupItem = crmForm.all.new_country.DataValue;
if (IsNull(lookupItem) == false)
{
var id = lookupItem[0].id;
crmForm.all.new_province.additionalparams = 'search=' + encodeURIComponent(id);
}
else
{
crmForm.all.new_province.additionalparams = 'search=' + encodeURIComponent("{00000000-0000-0000-0000-000000000000}");
}
lookupItem = crmForm.all.new_province.DataValue;
if (IsNull(lookupItem) == false)
{
var id = lookupItem[0].id;
crmForm.all.new_city.additionalparams = 'search=' + encodeURIComponent(id);
}
else
{
crmForm.all.new_city.additionalparams = 'search=' + encodeURIComponent("{00000000-0000-0000-0000-000000000000}");
}
lookupItem = crmForm.all.new_city.DataValue;
if (IsNull(lookupItem) == false)
{
var id = lookupItem[0].id;
crmForm.all.new_area.additionalparams = 'search=' + encodeURIComponent(id);
}
else
{
crmForm.all.new_area.additionalparams = 'search=' + encodeURIComponent("{00000000-0000-0000-0000-000000000000}");
}
6、分别在国家、省、市三个属性的onchange事件中加入以下js代码:
//国家属性
var lookupItem = new Array;
lookupItem = crmForm.all.new_country.DataValue;
if (IsNull(lookupItem) == false)
{
var id = lookupItem[0].id;
crmForm.all.new_province.additionalparams = 'search=' + encodeURIComponent(id);
}
else
{
crmForm.all.new_province.additionalparams = 'search=' + encodeURIComponent("{00000000-0000-0000-0000-000000000000}");
}
crmForm.all.new_city.additionalparams = 'search=' + encodeURIComponent("{00000000-0000-0000-0000-000000000000}");
crmForm.all.new_area.additionalparams = 'search=' + encodeURIComponent("{00000000-0000-0000-0000-000000000000}");
crmForm.all.new_province.DataValue = null;
crmForm.all.new_city.DataValue = null;
crmForm.all.new_area.DataValue = null;
//省属性
var lookupItem = new Array;
lookupItem = crmForm.all.new_province.DataValue;
if (IsNull(lookupItem) == false)
{
var id = lookupItem[0].id;
crmForm.all.new_city.additionalparams = 'search=' + encodeURIComponent(id);
}
else
{
crmForm.all.new_city.additionalparams = 'search=' + encodeURIComponent("{00000000-0000-0000-0000-000000000000}");
}
crmForm.all.new_area.additionalparams = 'search=' + encodeURIComponent("{00000000-0000-0000-0000-000000000000}");
crmForm.all.new_city.DataValue = null;
crmForm.all.new_area.DataValue = null;
//市属性
var lookupItem = new Array;
lookupItem = crmForm.all.new_city.DataValue;
if (IsNull(lookupItem) == false)
{
var id = lookupItem[0].id;
crmForm.all.new_area.additionalparams = 'search=' + encodeURIComponent(id);
}
else
{
crmForm.all.new_area.additionalparams = 'search=' + encodeURIComponent("{00000000-0000-0000-0000-000000000000}");
}
crmForm.all.new_area.DataValue = null;
效果如下：
