json数据 提示框flash.now[:notice] flash.now[:alert]
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>
收获不会与付出成反比
