How do I pass a long number through javascript?

I want to convert Long date number from mongo db database to dd / mm / yyyy format in javascript.

When I put in a direct encoded value, like the following code, it gives the correct result:

function getDateIfDate(d) {
    var m = d.match(/\/Date\((\d+)\)\//);
    return m ? (new Date(+m[1])).toLocaleDateString('en-US', {month: '2-digit', day: '2-digit', year: 'numeric'}) : d;
}

console.log(getDateIfDate("/Date(1460008501597)/"));

Here is my code:

for(var i=0;i<keys;i++)
                {
                var tr="<tr>";
                tr+= "<td><input type='checkbox' name='record'></td>"
                tr+="<td>"+positionList[i]["fromDate"]+"</td>";
                var j = (positionList[i]["fromDate"]);
                console.log("value of j is =========="+j);
                console.log(getDateIfDate("/Date(j)/")); // actual conversion should happen here
}

What changes should I make to my code to get the date in the required format?

You can use momentjs for your case. It's very easy to use, if you want to format the date to DD / MM / YYYY , just add the following line:



var formattedDate = moment(new Date()).format("DD/MM/YYYY");

You should call a function like this getDateIfDate("/Date("+j+")/");

instead getDateIfDate("/Date(j)/")

it means you are passing in a string "/Date(j)/"

.

 
function getDateIfDate(d) {
    var m = d.match(/\/Date\((\d+)\)\//);
    return m ? (new Date(+m[1])).toLocaleDateString('en-US', {month: '2-digit', day: '2-digit', year: 'numeric'}) : d;
}


var j= 1460008501597;

console.log(getDateIfDate("/Date("+j+")/"));
Run codeHide result
