我的应用程序中有一个用于验证表单的 Javascript 函数,我在单击按钮时调用它。但是脚本不起作用。
脚本:
function payment() {
alert("hi");
var theuser = document.getElementById("<%=txtcardname.ClientID%>").value;
var thecardno = document.getElementById("<%=txtcreditdet.ClientID%>").value;
var thecvv = document.getElementById("<%=txtcvv.ClientID%>").value;
var matchname = theuser.match(userRegex);
var divcontent = document.getElementById("<%=errorcontent.ClientID%>");
var msglbl = document.getElementById("<%=lblerror.ClientID%>");
var ermsg = "";
/*username validation*/
if (matchname == null) {
ermsg += "<li class='logli'>Username is Empty or Invalid.</li>";
}
/*Mobile validation*/
if (themobile.length != 10) {
ermsg += "<li class='logli'>Enter Your CardNumber Correctly.</li>";
}
/*Email validation*/
if (thecvv.length!=3) {
ermsg += "<li class='logli'>Enter Ur Cvv Correctly.</li>";
}
if (ermsg != "") {
divcontent.style.display = "block";
divcontent.style.background-colour="Aqua";
divcontent.style.border = "1px solid #ff0000";
divcontent.style.width = "100%";
divcontent.style.margin = "0px 0 10px 15px";
msglbl.style.display = "block";
msglbl.style.margin = "0 0 15px 15px";
msglbl.innerHTML = "Please correct the below errors" + "<ul>" + ermsg + "</ul>";
return false;
}
return true;
}
ASPX:
<asp:Button ID="btnpay" runat="server" Text="PAY" CssClass="btnpaystyle" OnClientClick="if(!payment())return false;"/>
注意:我payment()
在按钮的 clientclick 事件中调用该函数。
