简介
本例主要采用vue-cli配合webpack来创建项目,采用了VueRouter,引入axios库调用后端API,渲染数据,实现了增量改查功能。
一、创建项目
"dependencies": {
"vue": "^2.5.2",
"vue-router": "^3.0.1",
"axios": "^0.18.0"
}
import Vue from 'vue'
import App from './App'
import router from './router'
import axios from 'axios'
Vue.config.productionTip = false
Vue.prototype.$http = axios
/* eslint-disable no-new */
new Vue({
el: '#app',
router,
components: { App },
template: ' '
})
import Vue from 'vue'
import Router from 'vue-router'
Vue.use(Router)
export default new Router({
// 去除#的hash模式
mode: "history",
routes: [
{
path: '/',
name: 'Index',
component: resolve => require(['../components/Index.vue'], resolve)
},
{
//任务中心
path: '/task',
name: 'Task',
component: resolve => require(['../components/Task.vue'], resolve)
},
{
//个人中心
path: '/ucenter',
name: 'UCenter',
component: resolve => require(['../components/UCenter.vue'], resolve)
}
]
})
<router-link to="/">
<img src="#" class="logo"/>
</router-link>
<router-link to="/task" class="nav-item">任务中心</router-link>
路径传参跳转:<router-link :to="'/course/' + course.courseId">
<img :src="course.cover" />
</router-link>
js跳转:_this.$router.push('/');
var _this = this;
this.$http.get('http://localhost:8080/api/courses').then(function(response) {
_this.courses = response.data;
});
<script>
export default {
name: 'CourseDetail',
data() {
return {
id: this.$route.params.id,
course: {}
};
},
created() {
var _this = this;
this.$http.get('http://localhost:8080/api/course/' + this.id).then(function(response) {
_this.course = response.data;
});
}
};
</script>
<script>
export default {
name: 'NewCourse',
data() {
return {
loginUserId: 1,
course: {
courseName: '',
courseClass: '',
cover: ''
}
};
},
methods: {
addCourse: function(course) {
var _this = this;
this.$http({
method: 'post',
url: 'http://localhost:8080/api/course',
data: {
userId: _this.loginUserId,
courseName: course.courseName,
courseClass: course.courseClass,
cover: course.cover,
finished: 0
}
}).then(function() {
alert('新增班课成功');
_this.$router.push('/');
});
}
}
};
</script>
15.DELETE
deleteCourse: function(courseId,index) {
var _this = this;
this.$http({
method: 'delete',
url: 'http://localhost:8080/api/course/' + courseId
}).then(function() {
alert('班课删除成功');
_this.courses.splice(index,1);
});
}
updateCourse: function(course) {
var _this = this;
this.$http({
method: "put",
url: "http://localhost:8080/api/course",
data: {
courseId: course.courseId,
courseName: course.courseName,
userId: this.id,
courseClass: course.courseClass,
cover: course.cover,
courseCode: course.courseCode,
finished: 1
}
}).then(function() {
alert("班课结束");
_this.$router.push("/");
});
}
