我对动态变量名称有疑问
我有像
ip1
ip2
ip3
dns1
dns2
...
这样的表单参数我知道多少,但我不知道如何在 Controller
def ipcount = params.count
for (i = 1; i = ipcount ; i++ ){
def systems = new Ip()
systems.inetAddress = params.ip+${i} <---- How do I create these variable name?
....
中创建变量名 最佳答案
只需将它们用双引号引起来即可:
def ipcount = params.int( 'count' )
def systemsList = (1..ipcount).collect { i ->
def systems = new Ip()
systems.inetAddress = params."ip${i}"
...
systems
}
