這讓我拉我的頭髮。網站上的按鈕有onclick=method()
,它不會調用該方法。該方法應該抓住所有的複選框,檢查他們的檢查狀態,並用true/false填充chk[]
數組。然後WebMethod
接受該數組,將其分解爲三個較小的數組並對組合執行檢查。就我所知,按鈕從不會調用方法開始。Javascript函數未被onclick調用
aspx頁面:
<fieldset id="Fieldset">
<button onclick="SendForm();">Send</button>
<button onclick="CancelForm();">Cancel</button>
</fieldset>
</form>
<asp:ScriptManager ID="ScriptManager1" EnablePageMethods="true" EnablePartialRendering="true" runat="server" />
<script type="text/javascript">
function SendForm() {
var email = $get("txtEmail").value;
var elLength = form1.elements.length;
var chk = new [42];
for (i = 0; i < elLength; i++) {
var count = 0;
var type = form1.elements[i].type;
if (type == "checkbox") {
if (form1.elements[i].checked) {
chk[count] = true;
}
else {
chk[count] = false;
}
count++;
}
else {
}
}
PageMethods.SendForm(email, chk, OnSucceeded, OnFailed);
}
</script>
代碼隱藏方法是致電:
[WebMethod]
public static void SendForm(string email, bool[] chk)
{
bool[] desc = new bool[14];
bool[] loc = new bool[14];
bool[] other = new bool[14];
for (int i = 0; i < 14; i++)
{
int count = i * 3;
desc[i] = chk[count];
loc[i] = chk[count + 1];
other[i] = chk[count + 2];
}
if (string.IsNullOrEmpty(email))
{
throw new Exception("You must supply an email address.");
}
else
{
if (IsValidEmailAddress(email))
{
for (int i = 0; i < 14; i++)
{
if (desc[i])
{
if ((loc[i]) && (other[i]))
{
throw new Exception("Invalid, two parameters selected");
}
else if (loc[i])
{
// do stuff
}
else if (other[i])
{
// do stuff
}
else
{
throw new Exception("Invalid, every exemption must have at least one reason selected");
}
}
else
{
throw new Exception("No exemptions have been selected");
}
}
}
else
{
throw new Exception("You must supply a valid email address.");
}
}
}
編輯!!: 運行頁面下面的腳本,而不是以前的劇本就像一個魅力。不知道爲什麼以前沒有工作。
<script type="text/javascript">
function SendForm() {
var email = $get("txtEmail").value;
var elLength = form1.elements.length;
for (i=0;i< elLength;i++) {
var type = form1.elements[i].type;
if (type == "checkbox" && form1.elements[i].checked) {
alert("true!");
}
else {
alert("false!");
}
}
PageMethods.SendForm(email, chk, OnSucceeded, OnFailed);
}
</script>
