01-01 vue使用雏形
<div id="box">
{{msg}}
</div>
<script>
window.onload= function(){
var c = new Vue({
el:"#box",//选择器
data:{
‘msg‘:‘welcome vue‘
}
});
}
</script>
01-02 v-model一般用于表单元素数据双向绑定
<div id="box">
<input type="text" v-model="msg">
<input type="text" v-model="msg">
<p>{
{msg}}</br>{{msg2}}</br>{{arr}}</br>{{json}}
</p>
</div>
<script>
// 知识说明:
// v-model:数据双向绑定
window.onload= function(){
var c = new Vue({
el:"#box",//选择器
data:{
‘msg‘:‘welcome vue‘,
‘msg2‘:‘12‘,
‘arr‘:[‘apple‘,‘oramge‘,‘pear‘],
‘json‘:{a:‘apple‘,b:‘orange‘,c:‘pear‘}
}
});
}
</script>
01-03 v-for循环数据
<div id="box">
<!--数组的循环-->
<ul><li v-for="value in arr">{{value}}</li></ul>
<hr>
<!--json的循环-->
<ul><li v-for="(v,k,index) in json">{{k}} {{v}} {{index}}</li></ul>
</div>
<script>
// 知识说明:
// v-for:数据循环
// json数据: (value,key,index) in json
// {{value}}:json的值
// {{key}}:json的key
// {{index}}:数据索引
window.onload= function(){
var c = new Vue({
el:"#box",//选择器
data:{
‘arr‘:[‘apple‘,‘oramge‘,‘pear‘],
‘json‘:{a:‘apple‘,b:‘orange‘,c:‘pear‘}
}
});
}
</script>
01-04 v-click等等基础事件
<div id="box">
<button type="button" v-on:click="show()">按钮</button>
<button type="button" v-on:click="add()">添加</button>
<br>
<ul><li v-for="value in arr">{{value}}</li></ul>
</div>
<script>
// 知识说明:
// 基础事件举例: v-on:click/mouseout/mouseover/dblclick/mousedown……
window.onload= function(){
var c = new Vue({
el:"#box",//选择器
data:{//数据
‘arr‘:[‘apple‘,‘oramge‘,‘pear‘],
},
methods:{//函数储存器
show:function(){
alert();
},
add:function(){
alert(this.arr);//this表示的是这个c=new Vue这个对象
this.arr.push(‘tomato‘);
}
}
});
}
</script>
01-05 点击按钮div消失：v-show(false/true)
<div id="box">
<button type="button" v-on:click="a=false">消失</button>
<div v-show="a" style="width:300px;height:300px;background:red;"></div>
</div>
<script>
// 知识说明:
// v-show="true/false"//true显示，false隐藏
window.onload= function(){
var c = new Vue({
el:"#box",//选择器
data:{//数据
a:true,
}
});
}
</script>
