Property 'currentStyle' does not exist on type 'Document'.ts

这个错误通常出现在 TypeScript 中使用 `currentStyle` 属性时，编译器无法识别该属性。这是因为 `currentStyle` 属性是 Internet Explorer 特有的属性，而 TypeScript 默认只包含标准 DOM 属性。

为了解决这个问题，你可以将 `currentStyle` 属性声明为 `any` 类型，或者将其定义为 `Element` 或 `HTMLElement` 类型。

例如，你可以这样声明 `currentStyle` 属性：

declare global {
  interface HTMLElement {
    currentStyle: any;
  }
}

这将在全局作用域中声明 `currentStyle` 属性为 `any` 类型。如果你只想在特定的文件中使用 `currentStyle` 属性，也可以将声明放在该文件的顶部。

另外，建议你尽量避免使用 `currentStyle` 属性，它已经过时并且存在一些性能问题。你可以使用 `getComputedStyle` 方法来代替它，该方法返回一个包含计算后样式属性的对象。

相关问题

function getStyleAttr(obj,ele){ if(obj.currentStyle){ return parseInt(obj.currentStyle[ele]) ; }else{ return parseInt(window.getComputedStyle(obj,null)[ele]) ; } }

这是一个获取元素样式属性值的函数。它接受两个参数：obj表示要获取样式的元素对象，ele表示要获取的样式属性名。

函数首先判断浏览器是否支持currentStyle属性，如果支持，则使用obj.currentStyle[ele]来获取样式属性值，并使用parseInt函数将其转换为整数型返回。

如果浏览器不支持currentStyle属性，则使用window.getComputedStyle(obj,null)[ele]来获取样式属性值，并同样使用parseInt函数将其转换为整数型返回。

请注意，这个函数假设样式属性值都是整数型，如果要获取非整数型的样式属性值，可以将parseInt函数去掉。

上述代码实现了一个类似于Element UI中的Dialog组件的拖拽和缩放功能。在使用时，只需要将 `v-dialog-zoom-out` 指令绑定到Dialog组件的容器元素上，即可实现拖拽和缩放功能。
