error SyntaxError: JSON.parse: unexpected non-whitespace character after JSON data [duplicate]

问题

I am getting Error : SyntaxError: JSON.parse: unexpected non-whitespace character after JSON data

my code:

<script>
    $(document).ready(function () {
        $('.edit1').on('change', function () {
                arr = $(this).attr('class').split(" ");
                var clientid = document.getElementById("client").value;
                account_id = document.getElementById("account_id").value;
                $(this).parent().next().find('input:checkbox').attr("checked", true);
                $.ajax({
                    type: "POST",
                    url: "clientnetworkpricelist/routestatusupdate.php",
                    data: "value=" + $(this).val() + "&rowid=" + arr[2] + "&field=" + arr[1] + "&clientid=" + clientid + "&account_id=" + account_id,
                    success: function (result) {
                        data = jQuery.parseJSON(result); //added line

                        var obj = data;

                        $('#CPH_GridView1_Status' + arr[2]).empty();
                        $('#CPH_GridView1_Status' + arr[2]).append(data.status);

                        $('.ajax').html($(this).val());
                        $('.ajax').removeClass('ajax');
                    }
                });
            }
        );
    });
</script>

And the JSON output:

{"status":"<img  src=\"image\/Equalf.png\" \/>","seleniumrouteupdate":"1","routeupdate":"100"}{"status":"<img  src=\"image\/Equalf.png\" \/>","seleniumrouteupdate":"1","routeupdate":"100"}{"status":"<img  src=\"image\/Equalf.png\" \/>","seleniumrouteupdate":"1","routeupdate":"100"}

回答1:

The problem is that in your JSON output you've got 3 objects:

{"status":"<img  src=\"image\/Equalf.png\" \/>","seleniumrouteupdate":"1","routeupdate":"100"}
{"status":"<img  src=\"image\/Equalf.png\" \/>","seleniumrouteupdate":"1","routeupdate":"100"}
{"status":"<img  src=\"image\/Equalf.png\" \/>","seleniumrouteupdate":"1","routeupdate":"100"}

which are just placed inline next to each other. Try to modify your PHP script to push all that objects into array and then return that array as output to get result like:

[
  {"status":"<img  src=\"image\/Equalf.png\" \/>","seleniumrouteupdate":"1","routeupdate":"100"},
  {"status":"<img  src=\"image\/Equalf.png\" \/>","seleniumrouteupdate":"1","routeupdate":"100"},
  {"status":"<img  src=\"image\/Equalf.png\" \/>","seleniumrouteupdate":"1","routeupdate":"100"}
]
