1.Link组件动态绑定URL


    
        
            
                默认链接
            
        
    

对应的js代码


    new Vue({
        el: '#home',
        data: {
            href: ''
        },
        mounted() {
            this.init()
        },
        methods: {
            init() {
                this.href = "https://www.baidu.com/"
            }
        }
    })

2.Radio 用法


    备选项1
    备选项2
    备选项3

对应的js代码


    new Vue({
        el: '#home',
        data: {
            addType: null       # 必须声明绑定的值，否则页面无法渲染
        },
        mounted() {
            this.init()
        },
        methods: {
            init() {

            },
            radioChange() {
                console.log(this.addType)
            }
        }
    })

当选项被选中时，会调用radioChange方法。

3.Checkbox用法

方式一：

对应的js代码


    new Vue({
        el: '#home',
        data: {
            num: ''
        },
        mounted() {
            this.init()
        },
        methods: {
            init() {

            },
            checkChange() {
                console.log(this.num)
            }
        }
    })

当标签中的值改变时，会调用handleChange方法。

方式二：


搜索

对应的js代码


    new Vue({
        el: '#home',
        data: {
            num: '',
        },
        mounted() {
            this.init()
        },
        methods: {
            init() {

            },
            getSearch() {
                console.log(this.num)
            }
        }
    })

当搜索按钮被点击时，会触发getSearch方法，获取到num的值。

4.Select 用法

方式一：

el-option中只需要声明key和value的值即可


    

搜索

对应的js代码


    new Vue({
        el: '#home',
        data: {
            options: [],
            value: ''
        },
        mounted() {
            this.init()
        },
        methods: {
            init() {
                this.options = [
                    {
                        value: '黄金糕',
                        label: '黄金糕'
                    }, {
                        value: '双皮奶',
                        label: '双皮奶'
                    }, {
                        value: '蚵仔煎',
                        label: '蚵仔煎'
                    }, {
                        value: '龙须面',
                        label: '龙须面'
                    }, {
                        value: '北京烤鸭',
                        label: '北京烤鸭'
                    }
                ]
            },
            getSearch() {
                console.log(this.value)
            }
        }
    })

可以先声明options为空数组，然后在init方法中为options数组赋值(可以异步请求后端数据，将后端响应数据赋值)

当搜索按钮被点击时，会触发getSearch方法，获取到el-select被选中的值。

方式二：


    

对应的js代码


    new Vue({
        el: '#home',
        data: {
            options: [],
            value: ''
        },
        mounted() {
            this.init()
        },
        methods: {
            init() {
                this.options = [
                    {
                        value: '黄金糕',
                        label: '黄金糕'
                    }, {
                        value: '双皮奶',
                        label: '双皮奶'
                    }, {
                        value: '蚵仔煎',
                        label: '蚵仔煎'
                    }, {
                        value: '龙须面',
                        label: '龙须面'
                    }, {
                        value: '北京烤鸭',
                        label: '北京烤鸭'
                    }
                ]
            },
            selectChange() {
                console.log(this.value)
            }
        }
    })

当select选项改变时，会调用selectChange方法。

如需要在下拉菜单中选中多个值中，可以在el-select标签中加入multiple选项，多选中标签的结果是一个数组。


    

7.Cascader 级联菜单组件用法

对应的js代码


    new Vue({
        el: '#home',
        data: {
            options: [],
            value: ''
        },
        mounted() {
            this.init()
        },
        methods: {
            init() {
                this.options = [
                    {
                        value: 'zhinan', label: '指南',
                        children: [
                            {
                                value: 'shejiyuanze', label: '设计原则',
                                children: [
                                    {value: 'yizhi', label: '一致'},

                                    {value: 'kekong', label: '可控'}
                                ]
                            }, {
                                value: 'daohang', label: '导航',
                                children: [
                                    {value: 'cexiangdaohang', label: '侧向导航'},
                                    {value: 'dingbudaohang', label: '顶部导航'}

                                ]
                            }, {

                        ]
                    }
                ]
            },
            getSearch() {
                console.log(this.value)
            }
        }
    })

可以先声明options为空数组，然后在init方法中为options数组赋值(可以异步请求后端数据，将后端响应数据赋值)

需要选中值就触发方法时，可以加@change="handleChange"选项来绑定触发方法

需指定长度时，可以加选项

其选中结果为一个数组类型，可以直接加索引获取选中的值
