TypeScript简要定义,一个平铺的文档块数组,根据block_id和parent_id确定各块的父子关系,从而形成一个树: { /** 文档块唯一标识。*/ block_id: string; /** 父块 ID。*/ parent_id: string; /** 子块 ID 列表。*/ children: string[]; /** 文档块类型。*/ block_typ
e.preventDefault();vardt=e.dataTransfer;varfiles=dt.files;for(vari=0; i<files.length; i++) {varfile=files[i];varimageType=newRegExp("^image\/");if(!imageType.test(file.type))continue;//填充选择的图片到展示区varimg=document.createElement("img"); img.classList.add("obj"); img.file...
imageBlob=blob; },'image/png'); }; } } 2. 上传图片 实现将裁剪后的图片上传到服务器。这里我们使用FormData对象将Blob对象封装,并通过Fetch API将其上传到服务器。 uploadBtn.addEventListener('click', () =>{if(imageBlob) { const formData=newFormData(); formData.append('image', imageBlob, 'ima...

在上面的代码中,首先使用fetch函数发送HTTP请求获取图像数据。然后,将响应数据转换为Blob对象,并使用URL.createObjectURL函数创建一个临时的URL。接下来,创建一个img元素,并将临时URL赋值给其src属性。最后,将img元素添加到div容器中。 请注意,上述示例中的图像URL(https://example.com/image.jpg)是一个示例URL,你需...
