继上一篇,设置弹框次数以及自适应图片弹框,部分机型(vivo)老手机不显示的问题

news 来源：原创 2025/6/28 23:34:25

上一篇写的本来测试好多型号都无事, 今天下午公司的战斗机vivo横空冒出…
晕弹框直接显示都出不来了,现在还有用这种老的机型的,但是没办法咯~ 前端遇到这种兼容性的问题就要勇于解决
主要解决了这几点:

// 添加图片加载事件
<imgv-if="imageUrl":src="imageUrl"@load="handleImageLoad"@error="handleImageError"@click="handleImgClick"
/>// 图片加载完成后再显示
const handleImageLoad = () => {console.log('图片加载完成');imageLoaded.value = true;showPopup();
};

这确保了只有在图片真正加载完成后才显示弹框，避免了空白或闪烁。

多重渲染保护：

const showPopup = () => {requestAnimationFrame(() => {setTimeout(() => {isVisible.value = true;if (popupRef.value) {popupRef.value.style.transform = 'translateZ(0)';}}, 100);});
};

使用 requestAnimationFrame 和 setTimeout 的组合，确保在浏览器的下一帧渲染时才显示，这解决了 vivo 手机上的渲染时机问题。

显示状态控制：
const isVisible = ref(false);
const imageLoaded = ref(false);

const containerStyle = computed(() => ({
visibility: imageLoaded.value ? ‘visible’ : ‘hidden’
}));
使用独立的状态控制显示，而不是直接依赖数据加载。

硬件加速和性能优化：
.popup-container {
-webkit-transform: translateZ(0);
transform: translateZ(0);
backface-visibility: hidden;
perspective: 1000;
will-change: transform;
}

这些 CSS 属性强制启用硬件加速，提高渲染性能。
成功的关键在于：
正确的渲染时机：等待图片加载完成
可靠的显示控制：使用多重状态检查
性能优化：启用硬件加速
渲染队列：使用 requestAnimationFrame 确保正确的渲染顺序
这解决了 vivo 手机上的几个典型问题：
渲染时机不对导致的白屏
硬件加速缺失导致的显示问题
图片加载时机导致的布局问题
建议在类似场景下：
总是等待资源加载完成
使用多重渲染保护
添加必要的性能优化属性
保持良好的状态管理
