我使用此JavaScript(JQuery)来从API调用加载数据,但它给了我undefined
。它是这样的:
$(document).ready(function(){
//Autocomplete for Person
$(function() {
$.ajax({
type: 'GET',
url: urlReq+'/api/persons/1',
success: function(response) {
let modelArray = response;
let dataModel = {};
for (let i = 0; i < modelArray.length; i++) {
dataModel[modelArray[i].first_name] = null;
console.log('data is: '+modelArray[i].first_name);
}
$('input.autocomplete_person').autocomplete({
data: dataModel,
});
}
});
});
});
我的
urlReq+'/api/persons/1'
返回如下内容:{"452":{"id":452,"reference":"20190528155926096","first_name":"John","middle_name":"Smith","third_name":null,"family_name":"Doe"}}
但是我的问题是我的控制台给了我这个:
data is: undefined
最佳答案
{"452":{"id":452,"reference":"20190528155926096","first_name":"John","middle_name":"Smith","third_name":null,"family_name":"Doe"}}
这不是一个数组,因此您无法对其进行迭代。
