javascript error handeling
- by pankaj
I have a javascript function for checking errors which i am callin on OnClicentClick event of a button. Once it catch a error i want to stop execution of click event . But in my case it always it always executes the onclick event. Following is my function:
function DisplayError() {
if (document.getElementById('<%=txtPassword.ClientID %>').value.length < 6 || document.getElementById('<%=txtPassword.ClientID %>').value.length > 12) {
document.getElementById('<%=lblError.ClientID %>').innerText = "Password length must be between 6 to 12 characters";
return false;
}
var str = <%=PhoneNumber()%>;
if(str.length <10)
{
alert('<%=phoneNum%>'.length);
document.getElementById('<%=lblError.ClientID %>').innerText = "Phone Number not in correct format";
return false;
}
}
button html code:
<asp:Button runat="server" Text="Submit" ID="btnSubmit" ValidationGroup="submit" onclick="btnSubmit_Click" OnClientClick="DisplayError()"/>
It should not execute the button click event once it satisfies any of the IF condition in javascript function.
