私は、ウィザードを使用してクライアントに一連の大きな手順を実行しているASP.NET Webアプリに取り組んでいます。
手順の 1 つに、その場で一連の数値を計算することが含まれます...数値は正しく計算されますが、[次へ] をクリックしてからもう一度戻ると、一部の数値が保持されません。
計算機能はこちら
function CalculateFields() {
txtSellingPrice = document.getElementById('<%=txtSellingPrice.ClientID %>');
//I get all of the elements like this...
//...
var regexp = /[$,]/g;
//Empty value checks
SellingPrice = (SellingPrice == "" ? "$0" : SellingPrice);
BalanceSheet = (BalanceSheet == "" ? "$0" : BalanceSheet);
DownPayment = (DownPayment == "" ? "$0" : DownPayment);
susearn = (susearn == "" ? "$0" : susearn);
susrev = (susrev == "" ? "$0" : susrev);
balmult = (balmult == "" ? "$0" : balmult);
goodmult = (goodmult == "" ? "$0" : goodmult);
sellmult = (sellmult == "" ? "$0" : sellmult);
//Replace $ with String.Empty
SellingPrice = txtSellingPrice.value.replace(regexp, "");
BalanceSheet = txtBalanceSheet.value.replace(regexp, "");
DownPayment = txtDownPayment.value.replace(regexp, "");
susearn = txtSusEarn.value.replace(regexp, "");
susrev = txtSusRev.value.replace(regexp, "");
balmult = txtBalanceMult.value.replace(regexp, "");
goodmult = txtGoodwillMult.value.replace(regexp, "");
sellmult = txtSellingPriceMult.value.replace(regexp, "");
//Set the new values
txtGoodWill.value = "$" + (SellingPrice - BalanceSheet);
txtBalance.value = "$" + (SellingPrice - DownPayment);
txtSellingPriceMult.value = "$" + SellingPrice;
txtGoodwillMult.value = "$" + (SellingPrice - BalanceSheet);
txtBalanceMult.value = "$" + BalanceSheet;
if (chkTakeBack.checked == 1) {
txtVendorTakeBackPercentage.value = Math.round((SellingPrice - DownPayment) / SellingPrice * 100);
}
else {
txtVendorTakeBackPercentage.value = "0";
}
if (!(susearn == "") && !(susearn == "0") && !(susearn == "$0")) {
txtSusEarnPercentage.value = Math.round(susearn / susrev * 100);
txtBalanceMultPercentage.value = Math.round(balmult / susearn);
txtGoodwillMultPercentage.value = Math.round(goodmult / susearn);
txtSellingPriceMultPercentage.value = Math.round(sellmult / susearn);
}
else {
txtSusEarnPercentage.value = "0";
txtBalanceMultPercentage.value = "0";
txtGoodwillMultPercentage.value = "0";
txtSellingPriceMultPercentage.value = "0";
}
}
これらはすべて適切に計算され、ポストバック全体で値を保持します
txtGoodWill.value = "$" + (SellingPrice - BalanceSheet);
txtBalance.value = "$" + (SellingPrice - DownPayment);
txtSellingPriceMult.value = "$" + SellingPrice;
txtGoodwillMult.value = "$" + (SellingPrice - BalanceSheet);
txtBalanceMult.value = "$" + BalanceSheet;
ただし、これらのものはポストバック間で値を保持しません
if (chkTakeBack.checked == 1) {
txtVendorTakeBackPercentage.value = Math.round((SellingPrice - DownPayment) / SellingPrice * 100);
}
else {
txtVendorTakeBackPercentage.value = "0";
}
if (!(susearn == "") && !(susearn == "0") && !(susearn == "$0")) {
txtSusEarnPercentage.value = Math.round(susearn / susrev * 100);
txtBalanceMultPercentage.value = Math.round(balmult / susearn);
txtGoodwillMultPercentage.value = Math.round(goodmult / susearn);
txtSellingPriceMultPercentage.value = Math.round(sellmult / susearn);
}
else {
txtSusEarnPercentage.value = "0";
txtBalanceMultPercentage.value = "0";
txtGoodwillMultPercentage.value = "0";
txtSellingPriceMultPercentage.value = "0";
}
はtxtVendorTakeBackPercentage常に BLANK に戻り、他の 3 つは常に次のように戻ります。0
onkeyupフォーム フィールド内のイベントを使用して、これらの関数を起動しています。
If Not Page.IsPostBack Then
txtSellingPrice.Attributes.Add("onkeyup", "CalculateFields()")
txtBalanceSheet.Attributes.Add("onkeyup", "CalculateFields()")
txtDownPayment.Attributes.Add("onkeyup", "CalculateFields()")
txtSusRev.Attributes.Add("onkeyup", "CalculateFields()")
txtSusEarn.Attributes.Add("onkeyup", "CalculateFields()")
End If
どんな考え/助け/指示も大歓迎です。

私のページ読み込みイベントは次のようになります...
Protected Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs) Handles Me.Load
'Prepair page for advanced validation'
Dim cs As ClientScriptManager = Page.ClientScript
If Not cs.IsOnSubmitStatementRegistered(Me.[GetType](), "PrepareValidationSummary") Then _
cs.RegisterOnSubmitStatement(Me.[GetType](), "PrepareValidationSummary", "CheckForm()")
If Not Page.IsPostBack Then
'Part of the client side math'
txtSellingPrice.Attributes.Add("onkeyup", "CalculateFields()")
txtBalanceSheet.Attributes.Add("onkeyup", "CalculateFields()")
txtDownPayment.Attributes.Add("onkeyup", "CalculateFields()")
txtSusRev.Attributes.Add("onkeyup", "CalculateFields()")
txtSusEarn.Attributes.Add("onkeyup", "CalculateFields()")
私の実際の aspx ページは 2400 行を超えているため、すべてを投稿するつもりはありません。これは、パーセンテージ フィールドが値を保持していないセクションです。
