How to nest objects when building JSON with JSONObject

Image
By User



I'm trying to encode this string for a POST request. Can anyone tell me how I can encode







{"jsonrpc": "2.0", "method": "Files.GetSources", "params":{"media":"music"}, "id": 1}







So far I have







JSONOjbect obj = new JSONObject();

obj.put("jsonrpc", "2.0");

obj.put("method", "Files.GetSources");







But I'm not sure how to put in the rest - can anyone help?

    If you're asking how you'd put the nested params object in there, you'd probably do:

    JSONObject params = new JSONObject();
    params.put("media", "music");

    obj.put("params", params);




    To use an array (per your comments below), you'd do something like this:

    JSONArray properties = new JSONArray();
    properties.put("resume");
    properties.put("genre");
    properties.put("studio");
    ...

    JSONObject params = new JSONObject();
    params.put("properties", properties);

    obj.put("params", params);

    You have two choices. You can create another object that holds "media":"music" and then put that in the original JSONObject or you can just pass this whole string into the JSONObject constructor and have it parse it for you.

    JSONOjbect obj = new JSONObject().put("jsonrpc", "2.0")
    .put("method", "Files.GetSources").put("id", 1)
    .put("params", new JSONObject.put("media", "music"));


    Chaining .put() like this is possible because put() returns the object it was called on - for this exact purpose.

    Well, if you do have the string before hand, you can simply do

    JSONObject object = JSONObject.getJSONObject("{\"jsonrpc\": \"2.0\", \"method\": \"Files.GetSources\", \"params\":{\"media\":\"music\"}, \"id\": 1}");

Why is this Javascript much *slower* than its jQuery equivalent?

By User
I have a HTML list of about 500 items and a "filter" box above it. I started by using jQuery to filter the list when I typed a letter (timing code added later): $('#filter').keyup( function() { var jqStart = (new Date).getTime(); var search = $(this).val().toLowerCase(); var $list = $('ul.ablist > li'); $list.each( function() { if ( $(this).text().toLowerCase().indexOf(search) === -1 ) $(this).hide(); else $(this).show(); } ); console.log('Time: ' + ((new Date).getTime() - jqStart)); } ); However, there was a couple of seconds delay after typing each letter (particularly the first letter). So I thought it may be slightly quicker if I used plain Javascript (I read recently that jQuery's each function is particularly slow). Here's my JS equivalent: document.getElementById('filter').addEventListener( 'keyup', function () { var jsStart = (new Date).getTime()...

Is it possible to have IF statement in an Echo statement in PHP

By User
Thanks in advance. I did look at the other questions/answers that were similar and didn't find exactly what I was looking for. I'm trying to do this, am I on the right path? echo " <div id='tabs-".$match."'> <textarea id='".$match."' name='".$match."'>". if ($COLUMN_NAME === $match) { echo $FIELD_WITH_COLUMN_NAME; } else { } ."</textarea> <script type='text/javascript'> CKEDITOR.replace( '".$match."' ); </script> </div>"; I am getting the following error message in the browser: Parse error: syntax error, unexpected T_IF Please let me know if this is the right way to go about nesting an IF statement inside an echo. Thank you.
