这样一个json数组
[ {"id":"1","name":"21g","dis":"33"},
{"id":"2","name":"21g","dis":"22"},
{"id":"3","name":"21g","dis":"3"},
{"id":"4","name":"21g","dis":"5"},
{"id":"5","name":"21g","dis":"12"}]
需要根据dis从小到大排序成
[{"id":"3","name":"21g","dis":"3"},
{"id":"4","name":"21g","dis":"5"},
{"id":"5","name":"21g","dis":"12"},
{"id":"2","name":"21g","dis":"22"},
{"id":"1","name":"21g","dis":"33"}]
