我从STOMP订阅中收到消息正文响应,如下所示:
“[{\” 名称\ “:\” 测试\ “\ ”版本\“:\ ”1.0.4 \“,\ ”寿命\“:25000}]”
迭代它我将它解析为json并得到它:
[{ “名称”: “测试”, “版本”: “1.0.4”, “寿命”:25000}]
现在,当我尝试迭代它时,我收到以下错误消息:
未捕获的TypeError:无法使用'in'运算符在[{“name”:“test”,“version”:“1.0.4”,“lifetime”:25000}]
中搜索'86'
任何人都可以帮助我并说出我做错了吗?
这是我的代码:
stompClient.subscribe('/topic/validation', function(validationMessage){
console.log(validationMessage.body);
// --> "[{\"name\":\"test\",\"version\":\"1.0.4\",\"lifetime\":25000}]"
var jsonObj = JSON.parse(validationMessage.body);
console.log(jsonObj);
// --> [{"name":"test","version":"1.0.4","lifetime":25000}]
$.each(jsonObj, function(i,item){
console.log(item);
});
});
提前感谢。
validationMessage的控制台日志:

答案 0 :(得分:0)
由于价值低于[]
。你需要经历两个$.each
var jsonObj = [{"name":"test","version":"1.0.4","lifetime":25000}];
$.each(jsonObj, function(){
$.each(this, function(i,item){
$('body').append('<div>'+ item +'</div>');
});
});
var jsonObj2 = {"name":"test","version":"1.0.4","lifetime":25000}; // no []
$.each(jsonObj2 , function(i,item){
$('body').append('<div>'+ item +'</div>');
});
//////////////////////////////////////////////////////////////
var jsonObj3 = JSON.parse('[{\"name\":\"test\",\"version\":\"1.0.4\",\"lifetime\":25000}]');
$.each(jsonObj3, function(){
$.each(this, function(i,item){
$('body').append('<div>'+ item +'</div>');
});
});
