检索模板中的json值

我从表中查询了以下对象，之后将各种对象放在下面的objarr中。如何在javascript中在UI中检索这些值

from django.core.serializers import serialize json = serialize("json", objarr) logging.debug(type(json)) response_dict.update({'objarr' : (json) }) return HttpResponse(simplejson.dumps(response_dict), mimetype = 'application/javascript') 

Logging.debug给出以下内容

  {'obj_arr': '[{"pk": 56, "model": "upload_info", "fields": {"emp_id": 13, "import_flag": 1, "resource": null, "feedback": "some feedabck", "hint": "test", "time": null, "created_by": 145, "access": 0, "keywords": "test1,test9", "type": 4, "error_flag": 0, }}, {"pk": 1156, "model": "upload_info", "fields": {"emp_id": 13, "import_flag": 1, "resource": null, "feedback": "some feedabck", "hint": "test", "time": null, "created_by": 145, "access": 0, "keywords": "test1,test9", "type": 4, "error_flag": 0, }}] } 

在UI中我尝试访问emp_id的值，我该怎么做

 function retrieve_data(formid) { var form = $(formid); form.ajaxSubmit({ dataType: 'json', success: function (data) { //Data is the rendered oject of resposne_dict if((data) { alert(load_flag); How to print emp_id,error_flag and other details here } } } ) ; } 

Answer 1

您需要下载json2.js文件并将其添加到您的应用程序中

在回复中试试这个

 if((data) { var response=eval("("+JSON.stringify(data)+")"); for(var i=0;i 

您将在变量emp中获得emp_id的值。

同样为别人做

 response.obj_arr[0].fields[i].import_flag response.obj_arr[0].fields[i].resource response.obj_arr[0].fields[i].feedback 

并将它们分配给变量......

您还可以尝试以下代码来完成这项工作：

 String.prototype.toArr = function() { eval("var obj = " + this); return obj ? obj : []; }; function retrieve_data(formid){ var form = $(formid); form.ajaxSubmit({ dataType: 'json', success: function (data) { if(data){ data = data.toArr(); alert(load_flag); alert(data['fields']["emp_id"]); // And likewise you can access all detail } } }); } 

希望这对你有用.. 🙂
