Hi.
I was using the version 5.x of Ajax and works fine (except by the array
as parameter).
In order to load a dropdownlist with a datatable i use the following
code (from 5.x), but this does not work on 6.x version (and the options
of use DataRow are not visible):
-- The problem: dataTable.value.Rows is undefined, and DataRow is
unknown --
Is posible found examples like in the 5.x version in order to check
what's the matter and upgrade my code.
esanchezfo.js.LoadDropDownListFromDataTable = function
(
dropdownlist, dataTable_table, fieldName_text,
fieldName_value, selectedValue, doSelectIfOnlyOne, disableIfOnlyOne,
fieldName_extraValue, fieldName_leftMark, fieldName_rigthMark,
bool_appendExtraValue,
elementId_textIfOnlyOne
)
{
var option;
if (esanchezfo.js.FilterAjaxError (dataTable_table.error)) { return; }
esanchezfo.js.ClearDropDownList (dropdownlist);
if
(
dataTable_table == null || dataTable_table.value == null ||
dataTable_table.value == 0 || dataTable_table.value.Rows.length
== 0
)
{
if (dropdownlist.size == 0)
{
option = document.createElement ('OPTION');
option.text = '- No hay -'
option.value = '';
dropdownlist.options.add (option, 0);
}
return false;
}
for (var i = 0; i < dataTable_table.value.Rows.length; i++)
{
option = document.createElement ('OPTION');
option.text = dataTable_table.value.Rows [i][fieldName_text];
option.value = dataTable_table.value.Rows [i][fieldName_value];
if (typeof (fieldName_extraValue) != "undefined")
{
if (fieldName_leftMark != "undefined") { option.text +=
fieldName_leftMark; }
else { option.text += " ("; }
option.text += dataTable_table.value.Rows
[i][fieldName_extraValue];
if (fieldName_rigthMark != "undefined") { option.text +=
fieldName_rigthMark; }
else { option.text += ")"; }
if (bool_appendExtraValue) { option.value += "|" +
dataTable_table.value.Rows [i][fieldName_extraValue]; }
}
dropdownlist.options.add (option, i);
}
if (dropdownlist.size <= 0)
{
option = document.createElement ('OPTION');
option.text = '- Seleccione uno -'
option.selected = true;
option.value = '';
dropdownlist.options.add (option, 0);
}
if (elementId_textIfOnlyOne != null && typeof
(elementId_textIfOnlyOne) != "undefined")
{
if (dataTable_table.value.Rows.length == 1)
{
esanchezfo.js.SetInnerHTMLFromText
(elementId_textIfOnlyOne,
dataTable_table.value.Rows [0][fieldName_text]);
esanchezfo.js.HideElementById (dropdownlist.id);
}
}
if (dataTable_table.value.Rows.length == 1)
{
if (doSelectIfOnlyOne) { dropdownlist.selectedIndex =
(dropdownlist.size > 0 ? 0 : 1); }
if (disableIfOnlyOne)
{
dropdownlist.selectedIndex = (dropdownlist.size > 0 ? 0
: 1);
esanchezfo.js.DisableElementById (dropdownlist.id);
}
return true;
}
if (selectedValue != null) { return
esanchezfo.js.SelectByValueDropDownList (dropdownlist, selectedValue);
}
return true;
}
