方法之間的這個變量和創建的區別是什麼?這些方法和創建之間有什麼不同?
如果我想改變方法'handleCurrentChange中的全局變量personas,apis,total,那麼我必須保存這個上下文。
但是爲什麼我可以直接在創建時使用它?
var vue = new Vue({
el: "#app",
personas: {},
apis: {},
total: '',
methods: {
submitForm: function(formName) {
var _this = this;
this.$refs[formName].validate(function(valid) {
if (valid) {
console.log('form validate successfule.');
} else {
console.log('form validate failed.');
}
});
},
handleCurrentChange: function (val) {
var _this = this;
this.$http.post('/persona/index', {
current: val,
size: this.pageSize
}, {emulateJSON: true}).then(function (response) {
_this.personas = response.body.data.personas;
_this.total = response.body.data.total;
}, function (response) {
console.log('Sorry, there's no response.');
});
}
},
created: function() {
this.$http.get('/persona/index').then(function (res) {
this.personas= res.body.data.personas;
this.total = res.body.data.total;
this.apis= res.body.data.apis;
});
}
});
