我在我的 spring 控制器中通過 ajax 調用傳遞了一組員工 ID 。function deleteEntries() { var empList = $('input[type=checkbox]:checked').map(function (_, el) { return $(el).val(); }).get(); if (empList.length !== 0) { var r = confirm("Are you sure want to remove multiple entries? \nWarning: This process cannot be undone"); if (r === true) { $.ajax({ type: 'Post', url: baseUrl + 'delete_all', data: { empList: empList }, success: function (successMsg) { location.reload(); }, fail: function (data) { unblockMyScreen(); alert('Failed to retrieve data'); } }); } } else { alert("Choose atleast single record to delete."); } }.現(xiàn)在在 UI 中，我有復選框，我還提供了通過一次選擇全部并刪除來刪除的功能?，F(xiàn)在，當我全選并按下刪除按鈕時，只會刪除單個記錄。但是，如果不全選，它工作正常

由于您的方法提前返回，因此只有一條記錄被刪除。要解決此問題，請創(chuàng)建一個布爾變量以返回方法控制，而不是返回 true/false，同時將長度減 1 以避免 ArrayIndexOutOfBoundsException。這是可能對您有所幫助的代碼片段
@RequestMapping(value = "/delete_all", method = RequestMethod.POST)
@ResponseBody
public boolean deleteMultipleRecord(@RequestParam(value = "empList[]", required = false) String[] empListToBeRemoved, HttpServletRequest request) {
Employee emp = new Employee();
for (int i = 0; i <= empListToBeRemoved.length-1; i++) {
boolean result = false;
if (!empListToBeRemoved[i].equals("0")) {
emp.setEmpIdEnc(empListToBeRemoved[i]);
try {
List<OrgStructureTagging> list = orgStructureTaggingDAO.findEmpByProperty("EMP_ID", emp.getEmpId());
for (OrgStructureTagging structureTagging : list) {
System.out.println("all ids of employees" + structureTagging.getEmployee().getName());
orgStructureTaggingDAO.delete(structureTagging);
}
result = true;
} catch (Exception e) {
e.printStackTrace();
log.error("Error Occured While updating the field");
result = false;
}
}
}
return result;
}
