如何在 jquery / javascript 中读取这个 json 数组

Question

嘿，我想读这个数组

{  
   "1":{  
      "name":"41.52862795108241,-5.397956371307373",
      "location":"41.52862795108241,-5.397956371307373",
      "banner":"http:\/\/wpwebsiteinaweekend.com\/wp-content\/plugins\/lifterlms\/assets\/images\/placeholder.png",
      "phone":"23232323232",
      "address":"karachi test karachi 7890"
   },
   "2":{  
      "name":"41.52862795108241,-5.397956371307373",
      "location":"41.52862795108241,-5.397956371307373",
      "banner":"http:\/\/wpwebsiteinaweekend.com\/wp-content\/plugins\/lifterlms\/assets\/images\/placeholder.png",
      "phone":"23232323232",
      "address":"karachi test karachi 7890"
   }
}

PS：我是编程新手，所以很难阅读它

我正在使用此代码，但它不起作用

$.each( obj, function( key, value ) {
  alert( key + ": " + value );
});

Answer 1

你必须做key.name，等等。因为这些是子元素。

 $.each( obj, function( key, value ) {
      console.log( key.name + ": " + value.name);
    console.log( key.location+ ": " + value.location);
    console.log( key.banner+ ": " + value.banner);
    console.log( key.phone+ ": " + value.phone);
    console.log( key.address+ ": " + value.address);
    });

原因

正如您在下面看到的，名称、位置、横幅和所有这些键都是“1”的子元素，依此类推。所以你实际上必须通过像我上面那样使用点表示法或括号表示法来指出这一点。希望这有帮助！

{  
   "1":{  
      "name":"41.52862795108241,-5.397956371307373",
      "location":"41.52862795108241,-5.397956371307373",
      "banner":"http:\/\/wpwebsiteinaweekend.com\/wp-content\/plugins\/lifterlms\/assets\/images\/placeholder.png",
      "phone":"23232323232",
      "address":"karachi test karachi 7890"
   },
   "2":{  
      "name":"41.52862795108241,-5.397956371307373",
      "location":"41.52862795108241,-5.397956371307373",
      "banner":"http:\/\/wpwebsiteinaweekend.com\/wp-content\/plugins\/lifterlms\/assets\/images\/placeholder.png",
      "phone":"23232323232",
      "address":"karachi test karachi 7890"
   }
}

如您所见。它有效：
