I know this is rather simple but I'm stuck at it and I'd really like some help
Here's a JSON string I'm generating.
[{"field1":3,"field2":"5","field3":"value3","field4":"value4"},{"field1":3,"field2":"8","field3":"value3","field4":"value4"},{"field1":3,"field2":"6","field3":"value3"}]
How do I extract the value associated with field1?
And how do I access elements of each of the distinct arrays?
try this code
$jsonString = '[{"field1":3,"field2":"5","field3":"value3","field4":"value4"},{"field1":3,"field2":"8","field3":"value3","field4":"value4"},{"field1":3,"field2":"6","field3":"value3"}]';
$json = json_decode($jsonString, true);
print_r($json);
Try this (in Javascript)
var jsonData=[{"field1":3,"field2":"5","field3":"value3","field4":"value4"},{"field1":3,"field2":"8","field3":"value3","field4":"value4"},{"field1":3,"field2":"6","field3":"value3"}];
if you get response as text then use jsonData=JSON.parse(yourResponseText);
for(var i=0;i<jsonData.length;i++){
alert('your required val:'+jsonData[i].field1);
}
In php
$data = json_decode($json);//$json is your json data
foreach ($data as $item) {
echo $item->field1
}

console.log(jQuery.parseJSON(' [{"field1":3,"field2":"5","field3":"value3","field4":"value4"},{"field1":3,"field2":"8","field3":"value3","field4":"value4"},{"field1":3,"field2":"6","field3":"value3"}]').field1);
In php way
$jsonString = '[{"field1":3,"field2":"5","field3":"value3","field4":"value4"},{"field1":3,"field2":"8","field3":"value3","field4":"value4"},{"field1":3,"field2":"6","field3":"value3"}]';
$json = json_decode($jsonString, true);
foreach($json as $item){
echo $item['field1'];
}
In php you can:
$json = json_decode($_GET['variable'];
try this,
var json = '[{"field1":3,"field2":"5","field3":"value3","field4":"value4"},{"field1":3,"field2":"8","field3":"value3","field4":"value4"},{"field1":3,"field2":"6","field3":"value3"}]';
$.each(jQuery.parseJSON(json), function () {
alert(this['field1']);
alert(this['field2']);
alert(this['field3']);
alert(this['field4']);
});
this is a simple array of json objects. so with jquery
var jsonArray = JSON.parse("your string");
for(var int i=0 ; i < jsonArray.length() ; i++){
var jsonObject = jsonArray[i];
Console.log(jsonObject.field1)
}
