Javascript validation not working in c#
Aug 19 2016 5:58 AM
Here is the javascript validation code:
function ValidateFrom() {
if (document.getElementById("<%=txtCategoryName.ClientID %>").value.trim() == "") {
document.getElementById("<%=dvMessage.ClientID %>").innerHTML = "Please enter Category.";
document.getElementById("<%=txtCategoryName.ClientID %>").focus();
document.getElementById("<%=txtCategoryName.ClientID %>").classList.add("ErrorControl");
// document.getElementById("<%=txtCategoryName.ClientID %>").style.outline = '1px solid red';
// document.getElmentById("<%=txtCategoryName.ClientID %>").style.border = '3px solid red';
return false;
}
if (document.getElementById("<%=txtCategoryDescription.ClientID %>").value.trim() == "") {
document.getElementById("<%=dvMsg.ClientID %>").innerHTML = "Please enter Category Description.";
document.getElementById("<%=txtCategoryDescription.ClientID %>").focus();
document.getElementById("<%=txtCategoryDescription.ClientID %>").classList.add("ErrorControl");
// document.getElementById("<%=txtCategoryDescription.ClientID %>").style.outline = '1px solid red';
return false;
}
}
<script>
function checkfunction(val) {
if (val != "") {
document.getElementById("<%=txtCategoryName.ClientID %>").classList.remove("ErrorControl");
// document.getElementById("<%=dvMessage.ClientID %>").style.display = 'none';
document.getElementById("<%=txtCategoryDescription.ClientID %>").classList.remove("ErrorControl");
// document.getElementById("<%=dvMsg.ClientID %>").style.display = 'none';
}
}
</script>
Here is the text box:
<div class="field">
<div id="dvMessage" runat="server" style="color: Red" >
</div>
<label>
Category Name <em>*</em>
</label>
<div>
<asp:TextBox ID="txtCategoryName" runat="server" CssClass="form-01-control" onkeyup="checkfunction(this.value)" placeholder="Enter Category Name" ></asp:TextBox>
</div>
<div id="dvMsg" runat="server" style="color: Red">
</div>
<label>
Category Description <em>*</em></label>
<div>
<asp:TextBox ID="txtCategoryDescription" runat="server" CssClass="form-01-control" onkeyup="checkfunction(this.value)" placeholder="Enter Category Description"></asp:TextBox>
</div>
<label>
Parent Category </label>
<div>
<asp:DropDownList ID="ddlParentCategory" runat="server" Width="250px" class="form-01-control">
</asp:DropDownList>
</div>
<label>
Category Image</label>
<div>
<asp:FileUpload ID="fuImage" runat="server" />
<asp:Image ID="imgCategory" Width="100" Height="100" runat="server" />
</div>
</div>
