解析特殊的Json数据Javascript

Question

我想解析儿子数据波纹管。我的代码适用于简单的儿子文件，但不适用于此代码。我尝试了许多不同的组合来获取我想要的数据。我不想得到标题和董事会栖息地，你以粗体显示。

我真的不知道我能做什么。

我的数据和JavaScript代码。

function loadData() { 

    var text = '{

有你的JSON代码的多个错误：

• 在此行中的明星：* * "Broad_Habi": "Rivers and streams" * * ,
• 空间在你的号码：12.322497107 1和8.1962176125 1

我正确格式化它为你：

} 

通过功能的代码循环将是：

var obj = JSON.parse(text); 
for(var i = 0; i < obj.features.length; i++) { 
    var featureTitle = obj.features[i].properties.title; 
    var featureHab = obj.features[i].properties.Broad_Habi; 
}
