我收到错误：SyntaxError: JSON.parse: unexpected non-whitespace character after JSON data

我的代码：

<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>

JSON输出：

{"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"}

问题是在你的JSON输出中你有3个对象：

{"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"}

它们只是紧挨着排列。尝试修改PHP脚本以将所有对象推送到数组中，然后将该数组作为输出返回以获得如下结果：

[
  {"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"}
]
