$ .parseJSON抛出错误时尝试显示错误

Question

当我从服务器获取一些无法解析的数据时，尝试块死在IE8中杀死页面

 var statusData='';
            try
            {
                statusData = $.parseJSON(responseText);
            }
            catch(e)
            {
                statusData = $.parseJSON( '[message=>"Some error occured",Status=>false]');
            }

Answer 1

var jsonData = { "objects" : [ { "type" : "image", "left" : 167, "top" : 97, "width" : 480, "height" : 240, "id" : "DIN8DIF1", "userId" : "ITNTMB1B", "userName" : "Developer 1", "createTime" : "2016-01-08 14:45:28", "lastModify" : "2016-01-08 14:45:28", "src" : "data:video/mp4;base64,//data url "filters" : [], "crossOrigin" : "" }, ], "background" : "#ffffff", "width" : 750, "height" : 530 } canvas.loadFromJSON(jsonData); 中的代码可以替换为我假设的代码

catch

您有一个PHP序列化数组来代替JSON字符串，这就是您收到该错误的原因。
