Auto select the check box in rows

I am displaying table rows in the form. Each row has 5 columns, one of the columns is an (editable) textbox field.

ajaxLoading(true);
    $.post('<%=request.getContextPath()%>'+"/processServlet", postData,
            function(data) {
              var ctxPath='<%=request.getContextPath()%>';
                currentPosition = data.currentPosition;

                var items = $("#itemsTable");
                items.empty();
                if (data.items.length == 0) {
                    items.append($('<tr><td colspan=5 style="color:red;">No items<td></tr>'));
                }
                ;
                for (var i = 0; i < data.items.length; i++) {

                    editText = "";

                    items.append($("<tr " + zebra + "><td><a href=\"javascript: deviceView('" + data.items[i].id + "')\">" + data.items[i].num +
                            "</a></td><td>" + data.items[i].itemType +
            "</td><td><input type = 'checkbox' id = 'CheckBoxRow_' />" + data.items[i] +
                            "</td><td><input type = 'textbox' id = 'TextBoxRow_' value = '" + data.items[i].itemName +"' "/>" +
                            "</td><td>" + data.items[i].status +
                            "</td><td>" + data.items[i].date + "</td>" +
                           "<td>" + data.items[i].firmware + "<开发者_运维问答;td>" +
                            "<a href=\"javascript: deleteItem('" + data.items[i].id + "')\">Delete</a>" +
                            "</tr>"));

                ;
                ajaxLoading(false);
            }, "json");

How do I auto select the check box when the data is entered or modified in the textbox and save the data in the database?

bind to textbox onchange event and have it set the checkbox to checked=true once returned with a value (and not already checked).

$('#itemsTable input[type="checkbox"]').change(function(e){
  var $cb = $(this);
  if ($cb.is(':checked')){
    $cb.closest('tr').find('input[type="checkbox"][id^=CheckBoxRow_]').prop('checked','true');
  }
});

basically. though you really should not use HTML in an append, and should be building the objects with jQuery.
