I have a string like
params="domain:Abcd-E-Group,domaintype:com,Submit1:Search"

Now i want to convert this to

obj={domain:"Abcd-E-Group",domaintype:"com",Submit1:"Search"}

What I have tried:

I have tried JSON.parse(params); and eval(params);

Both are not working for me.

Solution 1

For the JSON.parse() to work, the string params must be in correct JSON syntax[^]
Try this:

C#

var params = '[{"domain":"Abcd-E-Group","domaintype":"com","Submit1":"Search"}]';
obj = JSON.parse(params);
alert(obj[0].domain);

let person='{firstName:"John", lastName:"Doe", id: 55, fullName:function(){return this.firstName+" "+this.lastName} }';

function strToObj(e){ var obj=new Function("return" +e); return obj() };

person=strToObj(person);

console.log(person.fullName())

In addition to the Peter's Solution,

If the string is in the format which you have provided, then you shall try this to convert it to a json object.

JavaScript

var params = "domain:Abcd-E-Group,domaintype:com,Submit1:Search";

          var jsonStrig = '[{';
          var items = params.split(',');
          for (var i = 0; i < items.length; i++) {
              var current = items[i].split(':');
              jsonStrig += '"' + current[0] + '":"' + current[1] + '",';
          }
          jsonStrig = jsonStrig.substr(0, jsonStrig.length - 1);
          jsonStrig += '}]';
          alert(jsonStrig); //[{"domain":"Abcd-E-Group","domaintype":"com","Submit1":"Search"}]
          var obj = JSON.parse(jsonStrig);
          alert(obj[0].domain);

Solution 3

I got my Solution with this.

obj={};
var params="domain:Abcd-E-Group,domaintype:com,Submit1:Search";

var KeyVal = params.split(",");

var i;
for (i in KeyVal) {
KeyVal[i] = KeyVal[i].split(":");
obj[KeyVal[i][0]]=KeyVal[i][1];
}
