How can i read this json string using a loop, the intention is to create/append a table with 3 columns containing in each row one of this json values, not sure how can i achieve it
{
"1":
{
"update":"Ja existe",
"numero":1,
"registro":"IBRAM - 2014"
},
"2":
{
"update":"Ja existe",
"numero":2,
"registro":"PM-SP - 2014"
},
"3":
{
"update":"Ja existe",
"numero":3,
"registro":"ARTESP - 2014"
}
}
If that is a string, then you can convert it to a JSON object and iterate through each element as follows:
var json = JSON.parse('THE JSON STRING');
for (key in json) {
var value = json[key];
// do whatever you wanna do with the value
}
Parse the JSON string & then for loop for retrieve value. Try something like below
<script>
var data = '{"1":{"update":"Ja existe","numero":1,"registro":"IBRAM - 2014"},"2":{"update":"Ja existe","numero":2,"registro":"PM-SP - 2014"},"3":{"update":"Ja existe","numero":3,"registro":"ARTESP - 2014"}}';
var json = JSON.parse(data);
for (var key in json) {
var value = json[key];
console.log(value.update);
console.log(value.numero);
console.log(value.registro);
}
</script>
you can use for in and loop on it
var myjson = $.parseJSON('< the json string>');
for (key in myjson ) {
var myitem = myjson[key];
alert(myitem.update);
}
but if in your code above its not a json string its already serialize in json ready to be iterated. see this http://jsfiddle.net/725cev7s/

$.parseJSON() then you can iterate on it using for in
