How to convert JSON with backwordslash

Question

I have JSON like this

var myVariable=[{"items": "SOFT TOUCH AVOCADO 125 ML x 6D","descriptions": "100mg","umo": "CTN","qty": 1,"price": 0,"lineamount": 0,"customerid": "ANG001","tdate": "11:0:2015","orderId": "Himansu12:9:707","bookorder": "ABCANG00197","FOC": 1}];

But We need JSON like this

 var stringtwo ="[{\"items\": 19760,\"descriptions\": 7,\"umo\": 18377,\"qty\":8,\"price\":8,\"lineamount\": \"22\" ,\"customerid\": 1960,\"tdate\": 7,\"orderId\": 1377,\"bookorder\":7,\"FOC\":7 }]";

so Please any one guide me how to convert JSON (myVaiable) to JSON (stringtwo).We Try to POST data to server. Webservice developed by .NET.SO We need POST JSON (stringtwo).But We Get JSON (myVaiable).

$.ajax({
            url:'http://183.82.0.221:1234/MyService.svc/PostOrderData/'+stringone+','+stringtwo+'',
            dataType:'jsonp',
            type:'get',
            cache:false,
            timeout: 2000,
            error: function(x, t, m) {
        if(t=="timeout") {
            alert("this app need internet connection so Please connect net first ");

        } else {
            //alert(t);
        }},
          success:function(data) {
                debugger;
    alert(data);
    console.log(data);
    },
});

We tried JSON data post to Server.but we got 400 bad request.

You just want to serialize in a JSON string. Read more about JSON in mozilla.

So use JSON.stringify like

var stringtwo = JSON.stringify(myVariable)

(BTW, you are lacking a Javascript tag)

Notice that you might use it multiply (but I can't guess why you would want to do that), for instance

var stringthree = JSON.stringify(stringtwo)

and even perhaps

var stringfour = JSON.stringify(stringthree)

etc

you could later call jquery.ajax like

$.ajax({ url: "http://some.url/goes/here",
         type: 'POST',
         data: stringfour, // but more probably stringtwo or stringthree
         success: function (gotdata) {
         }
         /// etc
       })

Serialize your object as JSON string and replace " with \"

// SiwachGaurav's version from http://stackoverflow.com/questions/1144783/replacing-all-occurrences-of-a-string-in-javascript
function stringReplaceAll(str, find, replace) {
    return str.replace(new RegExp(find.replace(/[-\/\\^$*+?.()|[\]{}]/g,'\\$&'),'g'),replace);
}

var myVariable = [{"items": "SOFT TOUCH AVOCADO 125 ML x 6D","descriptions": "100mg","umo": "CTN","qty": 1,"price": 0,"lineamount": 0,"customerid": "ANG001","tdate": "11:0:2015","orderId": "Himansu12:9:707","bookorder": "ABCANG00197","FOC": 1}];

var stringtwo = stringReplaceAll(JSON.stringify(myVariable), '\"', '\\"');

// stringtwo becomes "[{\"items\":\"SOFT TOUCH AVOCADO 125 ML x 6D\",\"descriptions\":\"100mg\",\"umo\":\"CTN\",\"qty\":1,\"price\":0,\"lineamount\":0,\"customerid\":\"ANG001\",\"tdate\":\"11:0:2015\",\"orderId\":\"Himansu12:9:707\",\"bookorder\":\"ABCANG00197\",\"FOC\":1}]"

Here's a trick I've used to do what you are asking (requires Intellij IDEA - not sure if Eclipse will do this). Also, assuming this is a once off, not part of a repeating process:

In any Java file, do this:

String json "";

Now, put the JSON that does not include the backslashes on the clipboard. Position the cursor between the quotes. Paste. Voila. Your JSON is escaped exactly as you requested.
