Question

我正在使用topojson将json文件转换为geofile，以便d3js geo api读取;但是，打字稿给我一个错误，说明回调函数返回的数据objects does not exist on type {}，我不确定如何解决这个问题

d3Data.json('https://s3-us-west-2.amazonaws.com/vida-public/geo/world-topo-min.json', function(error, world) {
    if (error) throw error;

    svg.insert("path", ".graticule")
        //Property objects does not exist on type {} 
        .datum(topojson.feature(world, world.objects.land))
        .attr("class", "land")
        .attr("d", path);

    svg.insert("path", ".graticule")
        //Property objects does not exist on type {} 
        .datum(topojson.mesh(world, world.objects.countries, function(a, b) { return a !== b; }))
        .attr("class", "boundary")
        .attr("d", path);
  });

只需将<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <ol class="top-assignee"> <li class ="1st-assignee"></li> <li class ="2nd-assignee"></li> <li class="3rd-assignee"></li> <li class="4th-assignee"></li> <li class="5th-assignee"></li> </ol>参数的类型设置为world，如下所示：

any

如@Duncan所述，最好将function (error, world: any) {...}属性转换为您期望的特定类型：

world

属性{} angular2上不存在属性
