一、在vue中,绑定事件,用v-on:事件类型, 如绑定一个点击事件, 我们可以这样子做
window.onload = function () {
var c = new Vue({
el : 'body',
methods : {
say : function(){
alert( '欢迎学习vue' );
}
}
});
}
添加方法,需要在vue实例的对象参数中,添加一项methods配置, methods是字面量方式,如上例,我们添加了一个say方法, 在按钮中绑定了一个点击事件,当事件触发的时候,执行say();
二、绑定双击事件,通过在methods方法中定义的函数,操作data中的数据
window.onload = function () {
var c = new Vue({
el : 'body',
data : {
arr : [ 10, 20, 30 ]
},
methods : {
change : function(){
this.arr.push( 40 );
}
}
});
}
上述例子,通过在按钮中绑定双击事件,当事件触发时,调用change方法, 通过this.arr 访问data中定义的数组arr, 向arr中push值40,那么data中的arr数据就被修改了,基于vue是MVVM驱动方式, 那么arr的修改 就会 实时更新到视图中.结果就是在ul下面新增一项li,值为40
三、指令:v-show,值为false/true. 当为false时,该元素隐藏,当为true时,该元素显示.
输出结果:
四、点击按钮,实现div显示与隐藏
