VUE2实现事件驱动弹窗示例

document.body.appendChild(instance.$el); // 将组件的element插入到body中
const Alert = (text,okText)=>{
if(instance.show === true) { //防止多次触发
return;
}
// 为弹窗数据赋值
instance.show = true;
instance.isAlert = true;
instance.okText = okText||'确定';
instance.message = text;
//返回一个promise对象，并为按钮添加事件监听
return new Promise(function(resolve,reject) {
instance.$refs.okBtn.addEventListener('click',function() {
instance.show = false;
resolve(true);
})
})
};
const Confirm = (text,okText,cancelText)=>{
if(instance.show === true) {
return;
}
instance.show = true;
instance.okText = okText||'确定';
instance.cancelText = cancelText||'取消';
instance.message = text;
return new Promise(function(resolve,reject) {
instance.$refs.cancelBtn.addEventListener('click',function() {
instance.show = false;
resolve(false);
});
instance.$refs.okBtn.addEventListener('click',function() {
instance.show = false;
resolve(true);
})
})
};
const Prompt = (text,inputType,defaultValue)=>{
if(instance.show === true) {
return;
}
instance.show = true;
instance.isPrompt = true;
instance.okText = okText||'确定';
instance.message = text;
instance.inputType = inputType || 'text';
instance.inputValue = defaultValue || '';
return new Promise(function(resolve,function() {
instance.show = false;
resolve(instance.inputValue);
})
})
};
