Javascript 返回false；单击“提交”按钮不工作

我一直试图让我的提交按钮返回假，如果我的代码中有任何错误，但它不断带我到一个坏页，我已经尝试在firefox控制台，没有错误。谢谢 返回值false位于底部 代码：

试试这个代码

function searchForm(){
//checks all the boxes to see if there are any errors
confirmFName();

confirmLName();

confirmEmail();

confirmAddress1();

confirmAddress2();

confirmCity();

confirmCode();

confirmUName();

confirmPass();
var flag=true;

//check to make sure a region is selected
if(nhlForm.regBox == "Choose a Country first", "Choose your Country First"){
    //shows error message
    showMessage(nhlForm.regBox, "error", "*Choose a region");
    showMessage(nhlForm.counBox, "error", "*Choose a country");
flag=false;
}

//checks if checkbox is checked, if not messgae will appear and form will not send
if(nhlForm.agebox.checked == true){
    showMessage(nhlForm.agebox, "bingo", "");
}else{

    //shows error message
    showMessage(nhlForm.agebox, "error", "You must be at least 14 to have an account"); 
flag=false;
}

if(nhlForm.checkbox.checked == true){

    showMessage(nhlForm.checkbox, "bingo", "");
}else{

    //shows error message
    showMessage(nhlForm.checkbox, "error", "You must accept the terms of use to continue"); 
flag=false;
}
 return flag;
}

和onSubmit=“return searchForm（）”在表单标记中，您必须向我们展示该函数是如何调用的。请显示该函数在何处调用。。或者请给我们看把小提琴

function searchForm(){
//checks all the boxes to see if there are any errors
confirmFName();

confirmLName();

confirmEmail();

confirmAddress1();

confirmAddress2();

confirmCity();

confirmCode();

confirmUName();

confirmPass();
var flag=true;

//check to make sure a region is selected
if(nhlForm.regBox == "Choose a Country first", "Choose your Country First"){
    //shows error message
    showMessage(nhlForm.regBox, "error", "*Choose a region");
    showMessage(nhlForm.counBox, "error", "*Choose a country");
flag=false;
}

//checks if checkbox is checked, if not messgae will appear and form will not send
if(nhlForm.agebox.checked == true){
    showMessage(nhlForm.agebox, "bingo", "");
}else{

    //shows error message
    showMessage(nhlForm.agebox, "error", "You must be at least 14 to have an account"); 
flag=false;
}

if(nhlForm.checkbox.checked == true){

    showMessage(nhlForm.checkbox, "bingo", "");
}else{

    //shows error message
    showMessage(nhlForm.checkbox, "error", "You must accept the terms of use to continue"); 
flag=false;
}
 return flag;
}
