初始化后显示 [object Object] 的价格滑块

Question

我正在开发 Vue 中的价格滑块，通过 API 调用返回所有产品数据。在其中一个对象中，返回所有商品的最低价和最高价之间的范围。

我的 .Vue 类中滑块实现的代码是：

        <price-slider
          code="price"
          id="reloadDiv"
          :priceRange="[{ from: minPrice }, { to: maxPrice }]"
          @change="$emitPriceSlider($event)"
        />

每当我拖动第一个滑块选项时，[object Object] 都会立即设置到末尾，包括正确的价格。然后单击第一个滑块选项，也会设置正确的（第一和最低）价格。

我似乎无法找到为什么价格滑块选项没有设置为正确的位置和值，而只是显示 [object, Object] 并想知道是否有人可以启发我。 我还尝试将 forceUpdate() 添加到元素中，但似乎无法使其正常工作。

滑块组件本身的代码如下：

<template>
  <div class="price-slider-container">
    
    {{ getMin }} {{ getMax }}
    <no-ssr placeholder="loading..." placeholader-tag="span">
      <vue-slider
        ref="priceSlider"
        v-model="value"
        v-bind="priceSliderOptions"
        :clickable="false"
        :min="getMin"
        :max="getMax"
        :tooltip-formatter="tooltipContent"
        @drag-end="setPrice"
      />
    </no-ssr>
  </div>
</template>

我认为你应该尝试在 get in 方法的返回中添加一个 toString
