Javascript: how to scroll automatically to a certain area of the page

document.getElementById("anchor-div").scrollIntoView();

Skeleton AJAX call with JQuery

var array_info = {};
  array_info['key1'] = $("#field1").val();
  array_info['key2'] = $("#field2").val();
  var array_info_json = JSON.stringify(array_info);
 
 //ajax call
 $.ajax({
        url: "file.php",
        type: "POST",
        data: {
            action: "parameter",
            field_data: array_info_json
        },
  
        success: function (data) {
            console.log(data);
            if (data != '') {
                $('#div_container').html('Sucess');
                dataArray = JSON.parse(data);   
            }
            else{
            
                alert('No data');
            

            }
        },
        error: function (a,b) { 
                alert('Error');
      }
    });

Tools: Yahoo! UI Library

«The Yahoo! User Interface Library is a set of utilities and controls, written in JavaScript, for building richly interactive web applications using techniques such as DOM scripting, HTML and AJAX. The UI Library Utilities facilitate the implementation of rich client-side features by enhancing and normalizing the developer's interface to important elements of the browser infrastructure (such as events, in-page HTTP requests and the DOM.»

Notes - Web: select all javascript function for checkboxes (multivalue too)

function selectAll(fieldname, bFlag) {
  var checkField = document.forms[0].elements[fieldname];
  if (checkField.length)
   {
     for (i=0; i<checkField.length; i++)
        {
           if (checkField[i].checked)
            {
               checkField[i].checked = bFlag;
           }
      }
   }
  else if (checkField.checked)
    {
       checkField.checked = bFlag;
   }
}

Notes - Web: bypassing the $$Return field

To avoid the processing of the $$Return field, save the document with the command:

@Command([FileSave])

If using Javascript then instead of using document.forms[0].submit(), create a button with the above formula and give it an id (ex:bt_save) and then on the submit script do:

 

document.all.bt_save.click()

 

The url of the document will be the original one (http://server_name//database_name/form_name?OpenForm), with "&Seq=1" (2,3,...) appended in the end.

Notes - Web: simulate notes client continue=false behaviour on web save

Form:
(Server_Name e Path_Info are CGI fields)

. field SaveOptions=0
. field $$Return= "[http://" + Server_Name + @Left(Path_Info;"nsf") + "nsf/0/"+ @Text(@DocumentUniqueID) + "?OpenDocument]"

WebQuerySaveAgent:
(if the validation fails, then the doc will not be saved because of the SaveOptions field value)

if (validateForm) doc.SaveOptions=1

Form - onload:
(optionally)

if (document.all.field_error.value!="") alert("Document not saved. \n Errors:" + document.all.field_error.value)
