js TOUCH_ONE_BY_ONE

  var listener = cc.EventListener.create({    //创建侦听事件
        event: cc.EventListener.TOUCH_ONE_BY_ONE,
        swallowTouches: true,
        onTouchBegan: function (touch, event) {    //开始点击
            return true
        },
        onTouchMoved: function (touch, event) {   //点击移动
            
        },
        onTouchEnded:function(touch, event) {     //点击结束,也就是松开点击的时候
        },
    })
    cc.eventManager.addListener(listener, this);   //将创建的侦听事件放进点击处理中心,这个是最重要的,只有加上这一句,这个点击事件才会生效

In Vue 3, the built-in directives like `v-model`, `v-if`, etc., provide a powerful way to manipulate DOM elements reactively. However, it should be noted that `v-touch` is not one of the official directives provided by Vue core or even within common UI libraries specifically mentioned in available documentation[^1]. For touch event handling which might be expected under something named `v-touch`, developers often rely on native JavaScript events such as `touchstart`, `touchmove`, and `touchend`. To implement custom touch gesture functionality similar to what could hypothetically be achieved using a `v-touch` directive, creating a custom directive would serve this purpose effectively. ### Creating Custom Touch Directive A simple example demonstrates how to create a custom directive called `v-touch`. This allows adding touch event listeners directly onto components: ```javascript import { createApp } from 'vue'; const app = createApp({}); app.directive('touch', { mounted(el, binding) { const type = binding.arg; el.addEventListener(`touch${type}`, (event) => { if (typeof binding.value === 'function') { binding.value(event); } }); }, }); ``` With this setup, any component can use `v-touch:start="handleTouchStart"` where `handleTouchStart` refers to methods defined inside the component's script section designed to handle specific logic when a user touches an element. For global registration ensuring accessibility across all instances without needing individual imports each time, modify accordingly based on given information about registering components globally but adapted here for directives[^2]: ```javascript // main.js or equivalent entry file import { createApp } from 'vue'; import App from './App.vue'; const app = createApp(App); app.directive('touch', {/* ... */}); // Registering custom v-touch directive app.mount('#app'); ``` This approach enables consistent behavior throughout applications while adhering closely to Vue’s reactivity principles and leveraging its lifecycle hooks efficiently.
