电商网站建设培训学校搜索引擎优化的基本原理

//鼠标悬浮效果

mounted() {this.setCurrentTask(0);
//对于id为mapAll的热区图，设置鼠标放置在上面有一个颜色 fillColor填充颜色 strokeColor边框颜色 strokeWidth边框宽度 fillOpacity 是设置热区填充颜色的不透明度的属性。 alwaysOn:true 保持常量$(function() {$('#mapAll').maphilight({fillColor: 'ff0000',strokeColor: "FFFFFF",strokeWidth: 3,fillOpacity: 0.6,});});
},

//点击效果
handleHighlight(id) {const escapedId = id;const $element = $(`#${escapedId}`);const data = $element.mouseout().data('maphilight') || {};data.alwaysOn = true;data.fillColor = "feeeed";$element.data('maphilight', data).trigger('alwaysOn.maphilight');setTimeout(() => {const data = $element.mouseout().data('maphilight') || {};data.fillColor = "ff0000";data.alwaysOn = false;$element.data('maphilight', data).trigger('alwaysOn.maphilight');}, 300);
},

好的设计思路：

​
<template><div><!-- Task Display --><div><h2>Task {{ currentTask.id }}: {{ currentTask.name }}</h2><p>{{ currentTask.details }}</p><img ref="mapAll" id="mapAll" src="../../assets/images/JIESHOUJI.png" usemap="#image-map"><map v-if="currentHotspots" name="image-map"><area v-for="(area, index) in currentHotspots" :key="index" :id="area.id" :title="area.title" :coords="area.coords" :shape="area.shape" @click="handleClick(area)"></map></div><!-- Global Navigation Buttons --><div><button @click="previousTask" :disabled="currentTaskIndex === 0">Previous</button><button @click="nextTask" :disabled="currentTaskIndex === tasks.length - 1">Next</button></div></div>
</template><script>
