Ajax submits asynchronous Verification

Simple and practical ajax asynchronous Verification Code

Jqueyr code:

Function submitPriceInfo (){

Var price = $ ("# price"). val ();

Var amount = $ ("# amount"). val ();

Var pbillId = $ ("# pbillId"). val ();

Var curentId = "$! Enterprise. id ";

Var billId = "$! TTraPbill. enterpirse. id ";

If (curentId = billId ){
Alert ("You cannot quote yourself !! ");
} Else {
$. Ajax ({
Type: "post ",
Url: "$! WebPath/usercenter/delegateManage/submitPprice.htm ",
Data: {price: price, amount: amount, pbillId: pbillId },
Async: false,
Success: function (data ){
Var codes = jQuery. parseJSON (data );

If (codes. code = "0 "){
Alert ("submission failed! ");
} Else {
If (codes. code = "1 "){
Alert ("the quotation is submitted successfully! ");
If (confirm ("Click OK to refresh. The delegated purchase page is displayed! ")){
Document. location. href = "$! WebPath/itTraPbillInfo/list.htm ";
}
} Else {
If (codes. code = "2 "){
Document. location. href = "$! WebPath/login.htm ";
}
}

}
}
});
}

}
