js中switch case循环实例代码

作者:

这篇文章主要介绍了js中switch case循环实例代码,有需要的朋友可以参考一下

复制代码 代码如下:

switch (objNameType) {

  case 'PD':

  valueUD = obj.id;

  id = objName;

  var loadVUD = UserData.load(exam, id);

  if (loadVUD == null || loadVUD == undefined || loadVUD == '') {

  var tmpTGId = obj.id.substr(0, obj.id.indexOf('_'));

  qNoTotalD[qIdNoStr[tmpTGId]]++;

  }

  break;

  case 'DANX':

  valueUD = obj.id;

  var objName = obj.name;

  var objNameTop = objName.substr(0,objName.indexOf('_'));

  id = objName;

  var loadVUD = UserData.load(exam, id);

  if (loadVUD == null || loadVUD == undefined || loadVUD == '') {

  var tmpTGId = obj.id.substr(0, obj.id.indexOf('_'));

  qNoTotalD[qIdNoStr[tmpTGId]]++;

  }

  break;

  case 'PP':

  valueUD = obj.id;

  var objName = obj.name;

  var objNameTop = objName.substr(0,objName.indexOf('_'));

  id = objName;

  var loadVUD = UserData.load(exam, id);

  if (loadVUD == null || loadVUD == undefined || loadVUD == '') {

  var tmpTGId = obj.id.substr(0, obj.id.indexOf('_'));

  qNoTotalD[qIdNoStr[tmpTGId]]++;

  }

  break;

  case 'text':

  valueUD = obj.value;

  id = "text_" + obj.id;

  var loadVUD = UserData.load(exam, id);

  if (loadVUD == null) {

  if (valueUD == null || valueUD == '') {

  return;

  }

  else {

  var tmpTGId = obj.id.substr(0, obj.id.indexOf('_'));

  qNoTotalD[qIdNoStr[tmpTGId]]++;

  }

  }

  else {

  if (valueUD == null || valueUD == '') {

  UserData.remove(exam, id);

  examAnswerKeyStr = removeStrWithcomma(examAnswerKeyStr, id);

  UserData.save(examinfo, "examAnswerKeyStr", examAnswerKeyStr, 1);

  var tmpTGId = obj.id.substr(0, obj.id.indexOf('_'));

  return;

  }

  }

  break;

  if (flag) {

  id = key;

  qNoTotalD[qIdNoStr[tmpTGId]]++;

  }

  }

  else {

  if (flag) {

  if (valueUD.indexOf(obj.id) == -1) {

  valueUD += "," + obj.id

  }

  }

  else {

  if (valueUD.indexOf(obj.id) != -1) {

  if (valueUD.indexOf(',' + obj.id) != -1) {

  valueUD = valueUD.replace(',' + obj.id, '');

  }

  else

  if (valueUD.indexOf(obj.id + ',') != -1) {

  valueUD = valueUD.replace(obj.id + ',', '');

  }

  else {

  UserData.remove(exam, key);
