现在我尝试获取此数组的值ScreenShot
我试图用
获得该值var L = e.Lookups
或
var L = e['Lookups']
但是当我试图获得那个数组时,该对象总是返回undefined。
有什么建议吗?
感谢您的帮助。
更新:
代码: 在这个方法中,我收到一个对象数组, 在调试模式下直接访问位置5,并且出现未定义的值
getQuestions(template: any) {
console.log('template: ', template)
console.log('1-template 5: ', template[5].Lookups);
console.log('2-template 5: ', template[5]['Lookups']);
var questions: QuestionBase<any>[] = [];
if(template !== undefined && template !== null) {
template.forEach(e => {
// Getting Lookups
switch(e.SimpleDataType){
case 'Number':
questions.push(
new TextboxQuestion({
Field: e.Field,
Label: e.Label,
Required: e.Required,
type: e.SimpleDataType,
ACL: e.ACL,
value: e.value || ''
})
);
break;

questions.push(

Field: e.Field,

// Field input type=File
questions.push(

return questions.sort((a, b) => a.order - b.order);
}

答案 0 :(得分:0)
试试这个:
getQuestions(template: any) {
template = [...template];
...
}
