需要一个标识符，而是看到'）'

Question

我收到此错误，

 Expected an identifier and instead saw ')'.

在这行代码中。有什么解决办法吗？

   for (; index < nPageFullItemCnt; index++) {
        strIndex = "0" + index;
        keyIndex = "popup_item_" + strIndex.substr(strIndex.length - 2, 2);
        keyItem = document.getElementById(keyIndex);

        setPopupKeyText(keyIndex, " ");

        keyItem.className = "popupLangItemNone";
        keyItem.langId = "";
    }

Answer 1

您没有将第一个参数传递给循环for()：

for (index = 0; index < nPageFullItemCnt; index++) 
{
    /* .. */
}
