Vue Watch Array or object

1. Regular Watch

data () {    return  {        0        }},watch: {    frontpoints (newvalue, OldValue) {        Console.log (NewValue)    }}

2, array of Watch

data () {    return  {        new Array (one). Fill (0)       }},watch: {winchips: {h Andler (NewValue, OldValue) {for   (Let i = 0; i < newvalue.length; i++) {  if (Oldvalue[i]!=true  }}

3. Watch for objects

data () {  return' local ' }        true }}

tips: As long as the attributes in the bet change (can be monitored), the handler function is executed, and if you want to monitor specific property changes, such as pokerhistory changes, the handler function is executed, you can use the calculated attribute computed to do the middle layer. Examples are as follows:
4, the object specific properties of the watch[utilization computed]

data () {  return' local ' }       }},computed: {pokerhistory () {  re Turnthis. Bet.pokerhistory}},watch: {pokerhistory (newvalue, OldValue) {console.log (newvalue)}}< /c8>
