Question

所以当我在嵌套数组中访问json时，我遇到了问题。我之前只有一个数组和我的。$每个函数完美地工作了json设置。但是我在修改它时遇到了麻烦。 JSON：

 {
 "tcontent": [{

  "Name": "Septicaemia",
  "url":"<a>",
  "image":"<div class='grid' style='background-image:url(img/anatomy/septicaemia.jpg);'>",
  "Variations": [{ 
      "condition":"Community-acquired",
      "organisms":"Staph. aureus",
      "antimicrobial":"Flucloxacillin ",
      "alternative":"(non anaphylaxis): ",
      "comments": "Perform full septic screen."

      }, {

      "Condition":"Community-acquired if intra- abdominal source suspected",
      "Organisms":"Predominantly Gram negatives and anaerobes Enterococci may also feature",
      "Antimicrobial":"Co-amoxiclav 1.2g iv tds",
      "Comments":"Perform full septic screen"

      }, {

      "Condition":"Healthcare-associated",
      "Organisms":"Varies",
      "Antimicrobial":"Piperacillin",
      "Alternative":"Seek advice from Consultant Microbiologist",
      "Comments":"Always"
     }]

   }, {

  "Name": "Infective Endocarditis (IE) (pending blood culture results)",
  "url":"<a>",
  "image":"<div class='grid' style='background-image:url(img/anatomy/endocarditis.jpg);'>"

  }, {

  "Name": "Central Nervous System Infections",
  "url":"<a>",
  "image":"<div class='grid' style='background-image:url(img/anatomy/cns.jpg);'>"

  }, {

  "Name": "Skin and Soft Tissue Infections",
  "url": "<a>",
  "image":"<div class='grid' style='background-image:url(img/anatomy/skin.jpg);'>"

  }, {

  "Name": "Diabetic patients with foot infections",
  "url": "<a>",
  "image":"<div class='grid' style='background-image:url(img/anatomy/foot.jpg);'>"

  }, {

  "Name": "Bone and Joint Infections",
  "url": "<a>",
  "image":"<<div class='grid' style='background-image:url(img/anatomy/bone.jpg);'>"

  }, {

  "Name": "Intravascular Line Infections",
  "url": "<a>",
  "image":"<div class='grid' style='background-image:url(img/anatomy/intravascular.jpg);'>"

  }, {

  "Name": "Urinary Tract Infections",
  "url": "<a>",
  "image":"<div class='grid' style='background-image:url(img/anatomy/urinary.jpg);'>"

  }, {

  "Name": "Respiratory Tract Infections",
  "url": "<a>",
  "image":"<div class='grid' style='background-image:url(img/anatomy/respiratory.jpg);'>"

  }, {

  "Name": "Gastrointestinal Infections",
   "url": "<a>",
   "image":"<div class='grid'        style='backgroundimage:url(img/anatomy/gastrointestinal.jpg);'>"

    }]

   }

这是我的javascript访问它。

$(function (){
var imp = "Json/therapy.json"
 $.getJSON(imp, function(data) {
   var info = "<br>";
   $.each(data.tcontent, function(i, item) {
  if(item.Name=='Septicaemia'){
     var search = item.Variations;
     $.each(item.Variations, function(j, subitem) {
      info += subitem.condition + subitem.organisms + subitem.antimicrobial + subitem.alternative + subitem.comments
       });
 $(info).appendTo(".menu");
 //alert(item)
   };
  });
 });
});

我在var搜索上尝试了很多变种，但似乎没有任何效果。我研究了很多类似的问题，并且我已经坚持了很久。任何可以解决这种情况的光都会非常感激！

无效的2个原因。

首先，javascript区分大小写，您的版本不同。

subitem.condition失败：

  "Condition":"Community-acquired if intra- abdominal source suspected",
  "Organisms":"Predominantly Gram negatives and anaerobes Enterococci may also feature",
  "Antimicrobial":"Co-amoxiclav 1.2g iv tds",
  "Comments":"Perform full septic screen"

所以将“条件”改为“条件”等等。

第二个原因是

将$(info).appendTo(".menu");更改为$(".menu").append(info);

<强>为什么吗

$(".menu").append(info)只需将字符串粘贴到选定的DOM元素中即可。

但你使用

$(info)...和jquery现在做各种奇特的事情。

尝试将其用作DOM选择器，或者创建一个新元素。

因为您的信息以<br> $（info）开头，尝试创建DOM元素并删除所有文本。仅留下<br>，因为br不能包含内容。

尝试删除初始<br>，然后您会看到以下错误：

Uncaught Error: Syntax error, unrecognized expression:Community-acquiredStaph. aureusFlucloxacillin...

例如，如果您要输入$("hahaha")，Jquery会尝试找到标记<hahaha>，因此当您移除<br>时，$(info)正在寻找标记{ {1}}。

但是因为你的字符串会包含奇怪的字符，如“ - （）”。它会失败。因此出现上述错误。

所以你只能添加这样的html：

<Community-acquiredStaph. aureusFlucloxacillin...>

或使用选择器

$("<span>hahah</span>").appendTo($(".menu"));

$("#myDiv").appendTo($(".menu"));工作时的示例：

$(info).appendTo(".menu");

使用以下json：

使用。$ each访问Json中的嵌套数组
