Question

I have a Textbox where I need to disable or enable that on some Conditions.

var stat = "any interger"
    if (statId != 1) {
     $('#<%=txt1.ClientID %>').attr("disabled", "disabled");
     } 
    else {
    $('#<%=txtBQty.ClientID %>').attr("enabled", "enabled");
     }

This one will work but after disable if the condition returns false also means It won’t enable the textbox.

Answer 1

enabled is not a valid attribute for textboxes. So the following will have no effect:

$('#<%=txtBQty.ClientID %>').attr("enabled", "enabled");

Instead use

$('#<%=txtBQty.ClientID %>').removeAttr("disabled");
