vue聲明周期八大階段

• created
• beforeMount
• mounted
• beforeUpdate
• updated
• beforeDestroy
• destroyed
  簡單說：創(chuàng)建——>掛載——>銷毀

  beforeCreate: function () {
    console.log('------beforeCreate創(chuàng)建前狀態(tài)------');
  }, created: function () {
    console.log('------create創(chuàng)建狀態(tài)------');
  }, beforeMount: function () {
    console.log('------beforeMount建前狀態(tài)------');
  }, mounted: function () {
    console.log('------mounted建前狀態(tài)------');
  }, beforeUpdate: function () {
    console.log('------beorreUpdate建前狀態(tài)------');
  }, updated: function () {
    console.log('------updated建前狀態(tài)------');
  }, beforeDestroy: function () {
    console.log('------beforeDestroy建前狀態(tài)------');
  }, destroyed: function () {
    console.log('------destroyed建前狀態(tài)------');
  },
