javascript to bring back only a certain portion of text (codeigniter & JQuery) -

i have below syntax:

$("#orderbynumber").autocomplete(   {    source: "get_orders_by_order_number",   messages:   {   noresults: '',   results: function() {}   },   select: function( event, ui )   {    var selectedobj = ui.item;    alert(selectedobj.value);   //get prices  $.post('get_sku_prices', {data:selectedobj.value},function(result) {   $('input[name^="deliveryweek"]').val(result[0]);  });    }   }); 

the alert returns, order number: customer name example 10827: massmart

what want strip away : massmart selectedobj.value want new variable(for example) selectedobjectorder = 10827

i can pass order number get_sku_prices function.

so like:

$("#orderbynumber").autocomplete(   {    source: "get_orders_by_order_number",   messages:   {   noresults: '',   results: function() {}   },   select: function( event, ui )   {    var selectedobj = ui.item;    alert(selectedobj.value);   //how finx code... var selectedobjectorder= before :(selectedobj.value);   alert(selectedobjectorder);    //get prices  $.post('get_sku_prices', {data:selectedobjectorder},function(result) {   $('input[name^="deliveryweek"]').val(result[0]);  });    }   }); 

thanks always.

js parseint() want.

var selectedobjectorder = parseint(jquery.trim(selectedobj.value));
