Question

我有一个REST API，它返回多选字段值作为[object Object]而不是实际值。

tableContent + =''+ arrayOfAllData [i] .Action_x0020_By_x003a_ +'';

字段Action_x0020_By_x003a_是Office365中的多选字段。我确实尝试使用arrayOfAllData [i] .Action_x0020_By_x003a_.choices.results和arrayOfAllData [i] .Action_x0020_By_x003a_.results，但返回的结果未定义。还使用了一些地图，但不起作用。任何建议都会有所帮助

您的选择列是一个对象。您需要遍历对象的内容。例如，选择字段（而不是下拉选择字段）是字符串数组。

观察/记录变量arrayOfAllData[i].Action_x0020_By_x003a_，您应该能够弄清楚如何遍历数据。
