Vue 给表格单元格加省略号和hover提示

基于antd vue的a-popover封装一下即可

<template>
  <a-popover
    v-model="visible"
    trigger="none"
  >
    <template #content>
      {{ text }}
    </template>
    <div
      class="ellipsis"
      @mouseenter="onMouseenter"
      @mouseleave="onMouseleave"
    >
      {{ text }}
    </div>
  </a-popover>
</template>

<script setup>
import { defineProps, ref } from 'vue';

defineProps({
  text: {
    type: String,
    default: '',
  },
});

const visible = ref(false);

const checkOverflow = element => element.scrollWidth > element.clientWidth;

let cancelEnter = true;
let cancelLeave = true;

const onMouseenter = (e) => {
  cancelEnter = false;
  cancelLeave = true;
  setTimeout(() => {
    if (!cancelEnter) {
      visible.value = checkOverflow(e.target);
    }
  }, 100);
};

const onMouseleave = () => {
  cancelLeave = false;
  cancelEnter = true;
  setTimeout(() => {
    if (!cancelLeave) {
      visible.value = false;
    }
  }, 120);
};

</script>

<style lang="less">
.ellipsis {
  white-space: nowrap;
  overflow: hidden;
  text-overflow: ellipsis;
}
</style>
