我正在修复这方面的bug &我不断得到“期待一个赋值或函数调用，而不是看到一个表达式”错误。

const CHARTID = "chart_id";
const FIELDID = "field_id";
const TIMEFILTERVALUE= "time_filter_input";
const TIMEFILTERUNIT = "time_filter_type"
const UNITFILTER = "unit_filter";

const constrcutFilterOptions = (field_id, chartId, timeFilterType, timeFilterUnit, unit)=> {

  var filterObj = {};
  !_.isNil(field_id) ? filterObj[FIELDID] = field_id : null;
  !_.isNil(chartId) ? filterObj[CHARTID] = chartId : null;
  !_.isNil(timeFilterType) ? filterObj[TIMEFILTERUNIT] = timeFilterType : null;
  !_.isNil(timeFilterUnit) ? filterObj[TIMEFILTERVALUE] = timeFilterUnit : null;
  !_.isNil(unit) ? filterObj[UNITFILTER] = unit : null;

  return filterObj;

}

你应该在三元条件之前写作业：

const CHARTID = "chart_id";
const FIELDID = "field_id";
const TIMEFILTERVALUE= "time_filter_input";
const TIMEFILTERUNIT = "time_filter_type"
const UNITFILTER = "unit_filter";

const constrcutFilterOptions = (field_id, chartId, timeFilterType, timeFilterUnit, unit)=> {

  var filterObj = {};
  filterObj[FIELDID] = !_.isNil(field_id) ? field_id : null;
  filterObj[CHARTID] = !_.isNil(chartId) ? chartId : null;
  filterObj[TIMEFILTERUNIT] = !_.isNil(timeFilterType) ? timeFilterType : null;
  filterObj[TIMEFILTERVALUE] = !_.isNil(timeFilterUnit) ? timeFilterUnit : null;
  filterObj[UNITFILTER] = !_.isNil(unit) ? unit : null;

  return filterObj;

}

试着写if条件语句，而不是写一个表达式，例如：{ nextCell？.getElementsByTagName（“input”）？.length > 0？nextCell？.getElementsByTagName（“input”）[0].focus（）：nextCell？.getElementsByTagName（“select”）？.length > 0？nextCell？.getElementsByTagName（“select”）[0].focus（）：“"; } solution：- function setKeyboardTabEvent（nextCell：（）=> void{ return（）=>{ if（nextCell？.getElementsByTagName（“input”）？.length > 0）{ nextCell？.getElementsByTagName（“input”）[0].focus（）;} if（nextCell？.getElementsByTagName（“select”）？.length > 0）{ nextCell？.getElementsByTagName（“select”）[0].focus（）;} };
