var AppQues = document.getElementById("_ctl1_PXP_SUN_APRSL_QSN_1", "_ctl1_PXP_SUN_APRSL_QSN_2", "ctl1_PXP_SUN_APRSL_QSN_3", "ctl1_PXP_SUN_APRSL_QSN_4");

AppQuest(AppQues, lang);

function AppQuest(ddl,lang) {

          if (lang.toLowerCase() == "de-de")


           {
               for (var i = 1; i < 5; i++) {
                   if (document.getElementById("_ctl1:PXP__APRSL_QSN_" + i).value == "") {
                       document.getElementById("_ctl1:PXP__APRSL_QSN_" + i).value = ["Ja", "Nein"];
                   }

推荐答案

你应该动态地从你的键字符串构建你的最后一部分，就像在下一个例子中一样：

You should build your last part from your key string dynamically like in the next example:

for( var  i = 1; i<4;i++)
{
 var uiElement=document.getElementById("_ctl1:PXP__APRSL_QSN_" + i);
 if (uiElement && uiElement.value == "") {
         uiElement.value = "Yes";
     }

}
