Loading 加载

加载数据时显示动效。

基础用法

自定义指令 v-loading，只需要绑定 boolean 值即可。

<script setup>
import { ref } from "vue";

const isLoading = ref(true);
const activeNames = ref([]);
</script>
<template>
  <div class="container" v-loading="isLoading">
    <er-collapse v-model="activeNames" accordion>
      <er-collapse-item title="Consistency" name="1">
        <div>
          Consistent with real life: in line with the process and logic of real
          life, and comply with languages and habits that the users are used to;
        </div>
        <div>
          Consistent within interface: all elements should be consistent, such
          as: design style, icons and texts, position of elements, etc.
        </div>
      </er-collapse-item>
      <er-collapse-item title="Feedback" name="2">
        <div>
          Operation feedback: enable the users to clearly perceive their
          operations by style updates and interactive effects;
        </div>
        <div>
          Visual feedback: reflect current state by updating or rearranging
          elements of the page.
        </div>
      </er-collapse-item>
      <er-collapse-item title="Efficiency" name="3">
        <div>
          Simplify the process: keep operating process simple and intuitive;
        </div>
        <div>
          Definite and clear: enunciate your intentions clearly so that the
          users can quickly understand and make decisions;
        </div>
        <div>
          Easy to identify: the interface should be straightforward, which helps
          the users to identify and frees them from memorizing and recalling.
        </div>
      </er-collapse-item>
      <er-collapse-item title="Controllability" name="4">
        <div>
          Decision making: giving advices about operations is acceptable, but do
          not make decisions for the users;
        </div>
        <div>
          Controlled consequences: users should be granted the freedom to
          operate, including canceling, aborting or terminating current
          operation.
        </div>
      </er-collapse-item>
    </er-collapse>
  </div>
</template>

<style scoped>
.container {
  padding: 10px;
}
</style>

自定义加载中组件内容

在绑定了 v-loading 指令的元素上添加 element-loading-text 属性，其值会被渲染为加载文案，并显示在加载图标的下方。 类似地， element-loading-spinner、element-loading-background 属性分别用来设定 加载图标、背景色值。

<script setup>
import { ref } from "vue";

const isLoading = ref(true);
const activeNames = ref(["1", "2"]);
</script>
<template>
  <div class="container">
    <er-collapse v-model="activeNames">
      <er-collapse-item
        title="Consistency"
        name="1"
        v-loading="isLoading"
        er-loading-text="Loading..."
        er-loading-spinner="circle-notch"
        er-loading-background="rgba(250, 250, 250, 0.8)"
      >
        <div>
          Consistent with real life: in line with the process and logic of real
          life, and comply with languages and habits that the users are used to;
        </div>
        <div>
          Consistent within interface: all elements should be consistent, such
          as: design style, icons and texts, position of elements, etc.
        </div>
      </er-collapse-item>
      <er-collapse-item title="Feedback" name="2" v-loading="isLoading">
        <div>
          Operation feedback: enable the users to clearly perceive their
          operations by style updates and interactive effects;
        </div>
        <div>
          Visual feedback: reflect current state by updating or rearranging
          elements of the page.
        </div>
      </er-collapse-item>
    </er-collapse>
  </div>
</template>

<style scoped>
:deep(.er-collapse-item) {
  padding: 10px;
}
</style>

全屏加载

当使用指令方式时，全屏遮罩需要添加fullscreen修饰符（遮罩会插入至 body 上） 此时若需要锁定屏幕的滚动，可以使用lock修饰符； 当使用服务方式时，遮罩默认即为全屏，无需额外设置。

<script setup>
import { ref } from "vue";
import { ErLoading } from "eric-ui";

const loading = ref(false);

function openLoading1() {
  loading.value = true;
  setTimeout(() => {
    loading.value = false;
  }, 2000);
}

function openLoading2() {
  const _loading = ErLoading.service({
    lock: true,
    spinner: "circle-notch",
    text: "加载中...",
    background: "rgba(255,255,255,0.5)",
  });
  setTimeout(() => {
    _loading.close();
  }, 2000);
}
</script>

<template>
  <er-button
    v-loading.fullscreen.lock="loading"
    type="primary"
    @click="openLoading1"
  >
    As a directive
  </er-button>
  <er-button type="primary" @click="openLoading2"> As a service </er-button>
</template>

服务方式调用

服务方式调用，可以自定义遮罩的文案，也可以通过 close 方法关闭。

import { ErLoading } from "eric-ui";

需要的时候通过以下方式调用

ErLoading.service(options);

LoadingService 会返回一个 Loading 实例，可通过调用该实例的 close 方法来关闭它

const loading = ErLoading.service(options);
nextTick(() => {
  loading.close();
});

TIP

以服务的方式调用的全屏 Loading 是单例的。 若在前一个全屏 Loading 关闭前再次调用全屏 Loading，并不会创建一个新的 Loading 实例，而是返回现有全屏 Loading 的实例
