How to convert json encoded PHP array to an array in Javascript?
This question already has an answer here:
There are three solution to this problem:
Call JSON.parse explicitly and pass the response text to it. The return value will be a JavaScript data type.
Set the dataType: 'json' option in your $.ajax call so that jQuery parses the JSON for you.
Set the right response headers for JSON in PHP. jQuery will detect the header and parse the JSON automatically as well.
If you want to modify the structure on the client side, have a look at Access / process (nested) objects, arrays or JSON.
http://api.jquery.com/jQuery.getJSON/
$.getJSON('ajaxfetch.php', function(data) {
var locations = [];
$.each(data, function(key, val) {
locations[val.deviceID] = [];
locations[val.deviceID].push(val.id);
locations[val.deviceID].push(val.latitude);
locations[val.deviceID].push(val.longitude);
});
});
Not 100% tested but it's along the right lines. Unsure where you get the location name from as it's not in the array so I used deviceID. Using getJSON should make your life easier.
确保你的输出是有效的JSON，然后在你的jQuery AJAX请求中指定dataType: "json" ：
$.ajax({
type: "POST",
url: "ajaxfetch.php",
dataType: "json",
success: function (result) {
console.log(result); //Now a JSON object
}
});
