You can call a controller function from view by using ajax.
The form is generated in controller as below.
TD(INPUT(_id='txt'+str(i+1)+'2',_name='txt'+str(i+1)+'2',value=row.lp_mcod,_style='width:100px;',_onblur='getDescr(this)'))
In the onblur event you call the javascript funciton defined below which in
turn calls the controller function get_descr and fills element with the
fetched results.
function getDescr(e){
var currentId = e.getAttribute('id'); //target.id;
//alert(currentId);
var nextId = currentId.substring(0,4);
var n = parseInt(currentId.substring(4,5));
var rowno = parseInt(currentId.substring(3,4));
//alert(rowno);
n = n + 1;
nextId = nextId + String(n);
nextIdN = '#' + nextId;
//alert(nextId);
currentIdN = '#' + currentId;
//var table = document.getElementById('tblItems');
//var row = table.rows[rowno];
//var tb = row.cells[2].childNodes[0];
//alert(tb.id);
//ajax('get_descr',[currentId],'txtItemh');
//fill_descr(rowno);
var request = $.ajax({
url: "/web_lp/lp/get_descr",
method: "GET",
data: { mcod : e.value},
dataType: "text"
});
request.done(function( msg ) {
$( nextIdN ).val( msg );
});
request.fail(function( jqXHR, textStatus ) {
alert( "Request failed: " + textStatus );
});
}
Hope this helps you.
