Uncaught TypeError: Cannot use 'in' operator to search for 'length' in "
This is the error I receive when I try to do a $.each to this JSON object :
{"type":"Anuncio","textos":["Probando esto","$ 20150515"],"submit":"codParameters?___DDSESSIONID\u003d14EA4721A904D6DD71591156996E29F7%3A%2FMobilTest"}
I have also tried to do the same with stringify, but I receive the same error:
{\"type\":\"Anuncio\",\"textos\":[\"Probando esto\",\"$ 20150515\"],\"submit\":\"codParameters?___DDSESSIONID\\u003d06CBEC9D1A53616EFF703A8C71FBC2B4%3A%2FMobilTest\"}"
If I remove parameters ___DDSESSIONID\\u003d06CBEC9D1A53616EFF703A8C71FBC2B4%3A%2FMobilTest from the object the $.each works fine.
Why might this be happening?
The in operator only works on objects. You are using it on a string. Make sure your value is an object before you using $.each. In this specific case, you have to parse the JSON:
$.each(JSON.parse(myData), ...);
maybe you forget to add parameter dataType:'json' in your $.ajax
$.ajax({
type: "POST",
dataType: "json",
url: url,
data: { get_member: id },
success: function( response )
{
//some action here
},
error: function( error )
{
alert( error );
}
});
this work for me
$.each(JSON.parse("[" + data + "]"))
$.each only works on objects . if your data is an array you can change it like this
$data = (object)$array;
