Numbers in Javascript (parseInt, parseFloat)?

Question

Python

Good afternoon!
In the dataTables table, all data is displayed as integers (int).


But the Totals calculation script returns NaN.

JSON returns data like this,

"unique_clicks": "1001", //iClicks
"events_count": 38, //iConv
"pending_revenue": 1000.0, //iPendingRevenue
"approved_revenue": 1500.0 //iApprovedRevenue

Then they are parsed here:

var stat_options = $.extend({
    "sAjaxSource": "/dashboard/graph/", 
    "aoColumns": [
        { "mData": "date" }, 			
        // {"mData":"clicks"}, 
        { "mData":"unique_clicks" }, 
        { "mData":"events_count" },
        { "mData":"approved" },
        { "mData":"pending" },
        { "mData":"rejected" }, 
        { "mData":"cpc" }, 
        { "mData":"ltr" }, 
        { "mData":"approval_rate" }, 
        // {"mData":"total_revenue"}, 
        // {"mData":"rejected_revenue"},
        { "mData":"pending_revenue" },
        { "mData":"approved_revenue" }  
    ], 
    "fnFooterCallback": function( nRow, aaData, iStart, iEnd, aiDisplay ) {
                var iClicks = 0
                var iConv = 0
                var iPendingRevenue = 0
                var iApprovedRevenue = 0
                for ( var i=0 ; i<aaData.length ; i++ )
                {
                    iClicks += aaData[i][1]*1;
                    iConv += aaData[i][3]*1;
                    iPendingRevenue += aaData[i][9]*1;
                    iApprovedRevenue += aaData[i][10]*1;
                }
                var nCells = nRow.getElementsByTagName('th');
                nCells[1].innerHTML = parseInt(parseFloat(iClicks));
                nCells[3].innerHTML = parseInt(parseFloat(iConv));
                nCells[9].innerHTML = parseInt(parseFloat(iPendingRevenue));
                nCells[10].innerHTML = parseInt(parseFloat(iApprovedRevenue));
                }
}, tables_options);

But neither parseFloat nor parseIng help.

Answer 1

Read the documentation, and do not duplicate questions (yesterday was the same)

Answer 2

advice for the future, if you are already using parseInt / parseFloat, then always try to put down the second argument (the base of the number system), because in the end it will sometimes lead to extremely disgusting and hard-to-find bugs. It is better to use explicit type casting through Number.

var myFloatVal= Number('4.4'),
      myIntVal =  Number('4');

Hello Roman-OverOffers. Is there any way to contact you about JSON?
