我正在尝试从网址中接收json，然后将其显示在页面上的g:select中，并且看起来一切正常，除了每个对象都显示为原始json(例如{id=1, regionCode=EC, regionName=EasternCape}而不是带有'id'，'name'，等等。这是我要拆分的json:
[{"regionCode":"EC","regionName":"Eastern Cape","id":1},
{"regionCode":"FS","regionName":"Free State","id":2},
{"regionCode":"GA","regionName":"Gauteng","id":3},
{"regionCode":"KZN","regionName":"Kwa-Zulu Natal","id":4},
{"regionCode":"LI","regionName":"Limpopo","id":5},
{"regionCode":"MP","regionName":"Mpumalanga","id":6},
{"regionCode":"NW","regionName":"North West","id":8},
{"regionCode":"NC","regionName":"Northern Cape","id":7},
{"regionCode":"WC","regionName":"Western Cape","id":9}]
这是我用来接收上述json的服务:
class GetRegionService {
def getRegion(){
try{
//I'm not using the actual URL in this example
def regionList = new JsonSlurper().parseText(new URL('http:url/regions/list/ZA/').text)
return regionList
}catch (all){
all.printStackTrace()
return false
}
}
}
这是我的 Controller 将json放在gsp页面上的方式:
class MainController {
def getRegionService
def index() {
def regions = getRegionService.getRegion()
[regions: regions]
}
}
这是显示选择内容的html代码段:
<div class="jumbotron">
<label for="setRegion" style="margin: 0 10px 0 50px">Region: </label>
<g:select name="setRegion" from="${regions}"/>
</div
最佳答案
我想到了。问题出在我的html中。选择应该看起来像这样:
<g:select name="setRegion" from="${regions}" optionValue="regionName" optionKey="regionCode"/>
