实现json、做出提示框
1、在controller中使用flash.now[:alert] = "str"方法来做print
def topodata
#@vnic = Vnic.all
#flash.now[:notice] = 'Message sent!'
#flash.now[:alert] = 'Message sent!'
@vnic = {
nodes: [{ name: 'bob', age: "22", awesome: "true" }, { name: 'bob', age: 22, awesome:true }],
links: [{ name: 'bob', age: "22", awesome: "true" }, { name: 'bob', age: 22, awesome:true }]
}
flash.now[:alert] = @vnic
respond_to do |format|
format.html
format.json { render json: @vnic } #这里会自动调用to_json
end
end
2、在view中使用链接来做提示 alert也可以换做confirm
<a href= 'http://192.168.1.251:3000/vnets' onclick="return(alert('<%= current_user.email %>'))">删除</a>
