Firebug是抱怨它有一個語法錯誤什麼錯這個JS
if (document.getElementById("fromAddress").value == "") ||
(document.getElementById("fromAddress").value == "Enter Address, City, Directions") {

你缺少的括號,這樣說你最好這樣寫它。
var from = document.getElementById("fromAddress").value;
if (from === "" || from === "Enter Address, City, Directions") {
你需要用的整個條件語句中parans:
if ((blah) || (blah))
^ ^
{
// as you were
}

你有括號的不匹配,試試這個:
if ((document.getElementById("fromAddress").value == "") ||
(document.getElementById("fromAddress").value == "Enter Address, City, Directions")){...}
更正表格:(刪除2個圓括號)
if(document.getElementById(「fromAddress」)。value ==「」|| document.getElementById(「fromAddress」)value ==「輸入地址,城市,方向」){
您應該在問題中多加一些代碼,以便我們可以在此處獲得一些上下文。假設在{後面有更多的代碼,你可以放入類似{...}的東西,所以我們知道這不是問題的一部分。示例代碼爲+ 1 + – Mnebuerquo 2010-08-26 20:02:33
