You know that javascript is a client-side programming language. But if you want to use the local database like MS-Access in your HTML page just using javascript? Here is some code that help you access the data of MS-Access DB in HTML page using JavaScript:
Adding a Record
function AddRecord() {
var adoConn = new ActiveXObject("ADODB.Connection");
var adoRS = new ActiveXObject("ADODB.Recordset");
adoConn.Open("Provider=Microsoft.Jet.OLEDB.4.0;Data Source='/\dbName.mdb'");
adoRS.Open("Select * From tblName", adoConn, 1, 3);
adoRS.AddNew;
adoRS.Fields("FieldName").value = "Quentin";
adoRS.Update;
adoRS.Close();
adoConn.Close();
}
Removing a Record
function DeleteRecord() {
var adoConn = new ActiveXObject("ADODB.Connection");
var adoRS = new ActiveXObject("ADODB.Recordset");
adoConn.Open("Provider=Microsoft.Jet.OLEDB.4.0;Data Source='\\dbName.mdb'");
adoRS.Open("Select * From tblName Where FieldName = 'Quentin'", adoConn, 1, 3);
adoRS.Delete;
adoRS.Delete;
adoRS.Close();
adoConn.Close();
}
Editing a Record
function EditRecord() {
var adoConn = new ActiveXObject("ADODB.Connection");
var adoRS = new ActiveXObject("ADODB.Recordset");
adoConn.Open("Provider=Microsoft.Jet.OLEDB.4.0;Data Source='\\dbName.mdb'");
adoRS.Open("Select * From tblName Where FieldName = 'Quentin'", adoConn, 1, 3);
adoRS.Edit;
adoRS.Fields("FieldName").value = "New Name";
adoRS.Update;
adoRS.Close();
adoConn.Close();
}
Querying data:
var pad = "C:\\My Documents\\data.mdb";
var cn = new ActiveXObject("ADODB.Connection");
var strConn = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + pad;
cn.Open(strConn);
var rs = new ActiveXObject("ADODB.Recordset");
var SQL = "SELECT * FROM datatable";
rs.Open(SQL, cn);
if(!rs.bof) {
rs.MoveFirst();
if(!rs.eof) {
document.write("<p>" + rs.fields(1).value + ", ");
document.write(rs.fields(2).value + ", ");
document.write(rs.fields(3).value + ".</p>");
}
}
else {
document.write("No data found");
};
rs.Close();
cn.Close();
