Javascript alert not getting displayed

Question

I have a form with a text box (Name) and a dropdown (Hotel).

<input type="text" name="lname" runat="server" id="LName" tabindex="1" onblur="if(this.value == '&nbsp;') { this.value = '&nbsp;Name'; }"
                            onfocus="if(this.value == '&nbsp;Name') { this.value = '&nbsp;'; }" value="&nbsp;Name"
                            style="color: #000000; border: 1px solid #757575; width: 234px; margin-top: 5px;" />
                        <div class="dropdownselect" style="margin: 15px 0;">
                            <asp:DropDownList ID="drhotel" runat="server" Style="border: 1px solid #757575; width: 234px;
                                height: 16px; *height: 18px;">
                            </asp:DropDownList>

If nothing is entered the text box will display "Name" by default. I am trying to validate on client click using the method below:

 function validatecust() {
    if (document.getElementById('<%= LName.ClientID %>').value == '&nbsp;Name') {
        alert('Please enter Name');
        document.getElementById('<%= LName.ClientID %>').focus();
        return false;
    }
    if (document.getElementById('<%= drhotel.ClientID %>').value == 'Select Hotel') {
        alert('Please select Hotel');
        document.getElementById('<%= drhotel.ClientID %>').focus();
        return false;
    }}

enter image description here

It is not showing alerting if I don't enter anything in the Name field. The Hotel validation works fine.

You need to put the internal encoding of the   entity in the string. I'm not sure how to do that. — Barmar

try:

if (document.getElementById('<%= LName.ClientID %>').value == 'Name') {

Leave the whitespace! If you want to indent the text in the textbox use a css padding!

If the above thing doesnt work, i think you should use a <asp:TextBox/> instead of a input runat server! Have you checked what the resulting value of LName.ClientID and the real Id on your input is?

Change this line:

if (document.getElementById('<%= LName.ClientID %>').value == '&nbsp;Name') {

to:

if (document.getElementById('<%= LName.ClientID %>').value == String.fromCharCode(160) + 'Name') {
