watch: {
 chatlog() {
 var container = this.$el.querySelector("#chatContainer");
 console.log(container);
 container.scrollTop = container.scrollHeight;
 }
 }

 watch: {
 chatlog() {
 console.log("chatlog change");
 this.$nextTick(() => {
 var container = this.$el.querySelector("#chatContainer");
 console.log(container);
 container.scrollTop = container.scrollHeight;
 })
 // document.getElementById('chatContainer').scrollTop = document.getElementById('chatContainer').scrollHeight+150;

 }
 }
