Question

How to find the count of empty text boxes?

$('input:text.jqValueText[value=" "]').length

This is working partially. But if i enter empty space, this fails…

is there any way to find the empty textbox in single line… it should not accept empty space

Try this one:

HTML:

<asp:TextBox ID="txt1" runat="server" CssClass="txt"></asp:TextBox>
<asp:TextBox ID="TextBox1" runat="server" CssClass="txt"></asp:TextBox>
<asp:TextBox ID="TextBox2" runat="server" CssClass="txt"></asp:TextBox>
<asp:TextBox ID="TextBox3" runat="server" CssClass="txt"></asp:TextBox>

JQuery:

var vEmptyTextBox = $(".txt").filter(function(){
    return $.trim($(this).val()) == '';
}).length;
alert(vEmptyTextBox);
