无法使用 json 向 jvectormap 显示数据

Question

我有一个问题，我已经处理了 2 天，但找不到解决方案。 我使用地图 jvectormap 插件和土耳其。 我从 mssql 数据库中获取数据，然后 Json 将其导入我的页面。 我将数据动态分配给“标记”变量，但我的数据在地图上绝对不可见。

有趣的是，当我手动将 json 数据添加到“markers”变量时，地图工作没有任何问题。

我可能把我的问题描述得有点奇怪，我很抱歉。

当我手动将出现在控制台中的数据添加到“markers”变量时，我可以毫无问题地看到数据。

var markers = [

                { latLng: [36.54, 31.99], name: 'Antalya', style: { r: 8, fill: '#3366cc' } },
                { latLng: [38.75, 30.53], name: 'Afyon', style: { r: 8, fill: '#dc3912' } },

Answer 1

您可以通过代码片段的颜色判断生成的数据类型存在很大差异。 基本上，您是在地图无法使用的markers数组中创建字符串，因为它需要对象。

很难说您的$.each函数应该是什么样子，因为您在 JavaScript 中使用了土耳其语，但它应该类似于下面的示例。

编辑：您的option.Koordinat是这样的单个字符串：

'37.00000000, 35.321333330'

并且需要将其转换为带有浮点数的数组：

[37.00000000, 35.321333330]`

您可以通过在, （逗号和空格）处拆分字符串来做到这一点。 然后你会有一个包含两个字符串的数组。 现在用map遍历数组并返回相同的值但作为一个数字。

$.each(data, function(index, option) {
  markers.push({
    latLng: option.Koordinat.split(', ').map(coord => parseFloat(coord)), 
    name: `Dosya Adedi: ${option.Adet}`,
    style: {
      r: 8, 
      fill: "#ff9900"
    }
  });
});
