Use keyboard "Enter" to function same as the custom button.

$(document).on("keypress","#txtParam",function (e) {
// Keypress event of the textbox

 var key = e.which;
 if(key == 13)  // the enter key code
  {
    $("input[id ='btnSearch']").click(); // simulates the function of "btnSearch"  button on ENTER.
    return false;
  }
});

Move a SharePoint List Item to another List using SPD 2013 Workflow

The option to move the list item directly was present in SPD 2010 workflows. But in SPD 2013 workflow, we need to  -

1) Create Item in new list with referencing the same column in the current item as shown in the screenshot below.
2) Delete current item.

Calculate days difference between 2 dates sharepoint + JQuery

// This function calculates the difference between the Date field of SharePoint and the current Date.
function calculateDays()
{
var myDate =  $('input[title="Date"]').val();
var chunks = myDate.split('/');
var formattedDate = new Date([chunks[1],chunks[0],chunks[2]].join("/"));
var currDate = new Date(new Date().getTime());
console.log( Math.floor((currDate-formattedDate)/(1000*60*60*24)));
return Math.floor((currDate-formattedDate)/(1000*60*60*24));
}
