json data char'＆'扰乱ajax发布请求数据

Question

i am generating a json string using JSON.stringify and my json string will be like

jsonstring=[{"step1":[{"nm":"John & joe"},{"title":"Hello & hai"}]},{"step2":[{"desc":"1234"},{"usr":"[e-mail]"}]}]` 

i am escaping & with \& and sending this json string to server through ajax.

$.ajax({
url:"test-usr-data.php",
type:"post",
data:"usrdata="+jsonstring,
success: function(response){
console.log("data is "+response); 
},
complete:function (jqXHR, textStatus){ 
console.log("ajax Request completed"+textStatus);
    }
});

The problem is with & char in json string, even though i am escaping & to \& data is not posted to server but ajax request status is success.

I tried removing & from json string it works fine and data is posting to server correctly.

Can any one help me in correct way to escaping & in json string.

Who told you that escaping in URL's works by prepending a backslash?

jQuery will take care of it, just do

data: {usrdata: jsonstring},

FYI: You could use encodeURIComponent as well

data: "usrdata=" + encodeURIComponent(jsonstring),
