我想在HTML页面中显示我的json的内容 我在数据库中读取了我的表格,我把它们放在一个列表中然后我试着解析json格式,但问题是我试图从json中检索一些数据我不能通过例如我想要显示名称或类似的东西
@APP.route('/scan',methods=['GET'])
def scan():
listscan = []
con = mdb.connect('localhost','testuser', 'test623', 'bd')
cur = con.cursor()
cur.execute("SELECT * FROM tablesd")
rows = cur.fetchall()
for row in rows:
chaine = "Id:" + str(row[0]) + ',' + "HOST_NAME:" + str(row[1]) + "," + "ADDRESS:" + str(row[2]) + "," + "IP:" + str(row[3]) + "," + "TIME:" + str(row[4]) + "," + "DATE:" + str(row[5]) + "," + "CONN:" + str(row[6]) + "," + "ETAT:" + str(row[7]) + "," + "NEWgh:" + str(row[8])
listscan.append(chaine)
print json.dumps(listscan)
return json.dumps(listscan)
function scan (){
$.ajax({
type: 'GET',
url: '/scan',
dataType: 'json',
success: function(json) {
alert('ok');
var lang = '';
$.each(json, function() {
lang += this['Id'] + "<br/>";
});
$("#donnees").html(lang);
},
error: function() {
alert('La requête n\'a pas abouti');
}
});
}
print json.dumps(listscan)的结果:
[&#34; ID:1,HOST_NAME:,地址:X:X:X:X:X:X,IP:172.xxx,时间:17:25,DATE:04/04/15中,CONN :0,ETAT:null,NEWgh:1&#34;,&#34; Id:2,HOST_NAME :, ADDRESS:Y:Y:Y:Y:Y:Y,IP:192.xxx,TIME:17:25 ,DATE:04/04/15中,CONN:0,ETAT:空,NEWgh:1&#34;]
我喜欢显示undefined我没有收到id。
答案 0 :(得分:1)
您应该更新您的回复(listscan),如:
var json = [
{'Id':1, HOST_NAME:'', ADDRESS:'x:x:x:x:x:x', IP:'172.x.x.x', TIME:'17:25', DATE:'04/04/15', CONN:0, ETAT:null, NEWgh:1},
{'Id':1, HOST_NAME:'', ADDRESS:'x:x:x:x:x:x', IP:'172.x.x.x', TIME:'17:25', DATE:'04/04/15', CONN:0, ETAT:null, NEWgh:1},
];
$.each(json, function() {
$('body').append(this['Id'] + '<br\>');
});
