我無法弄清楚我的代碼有什麼問題; JavaScript根本不運行。我試圖使用Firebug，但它的行爲就像頁面上沒有腳本。調試JavaScript的最佳方式是什麼？有沒有人看到這有什麼問題？調試Javascript

的Javascript：
function validateForm(){
var email = document.forms[0].email.value;
var names = document.forms[0].name.value;
var phone = document.forms[0].phone.value;
var emailm = email.match(/^[a-zA-Z0-9_.-][email protected][a-zA-Z0-9-]+.[a-zA-Z0-9-.]+$/)
var lnamem = names.match(/^([a-zA-Z]+)\S[a-zA-Z]([a-zA-Z]+))$/)
var fnamem = names.match(/^([a-zA-Z+)\S([a-zA-Z]\.\S)?[a-zA-Z]+))$/)
var phonem = phone.match(/^(1-?)?(\([2-9]\d{2}\)|[2-9]\d{2})-?[2-9]\d{2}-?\d{4}$/)
if (names == ""){
alert("Please enter your name.");
names.focus();
return false;
}
else if (fnamem == null || lnamem == null){
alert("Invalid name.");
names.focus();
return false;
}
if (email == ""){
alert("Please enter your e-mail address.");
email.focus();
return false;
}
else if (emailm == null){
alert("Invalid e-mail address.");
email.focus();
return false;
}
if (phone == ""){
alert("Please enter your phone number.");
phone.focus();
return false;
}
else if (phonem == null){
alert("Invalid number.")
phone.focus();
return false;
}
alert("Are you sure you would like to submit this form?");
names = names.value.toUpperCase();
return true;
}
你嘗試加入調試;在jscript代碼？嘗試一下並在IE中打開。確保禁用腳本調試從IE->工具 - >高級 – 2011-02-02 06:02:09
