javascript - Google Chart Tools and JSON -


on example https://google-developers.appspot.com/chart/interactive/docs/quick_start method data.addrows() takes list of lists.

i have uri (/data/mydata.json) returns data

[["canada", 66], ["turkey", 10], ["hungary", 23], ["italy", 49]]

using jquery's $.parsejson(), error syntaxerror: json.parse: unexpected character

how data method in format wants?

update

i ran alert($.parsejson('/data/mydata.json')) , parsed , displayed data fine. seems data.addrows() 1 throwing error.

here full code:

google.load('visualization', '1.0', {'packages':['corechart']}); google.setonloadcallback(drawchart) function drawchart(){ var data = new google.visualization.datatable(); data.addcolumn('string', 'country'); data.addcolumn('number', 'node count'); data.addrows($.parsejson('/data/mydata.json'));  var options = {'title':'tor nodes country',            'width':800,            'height':600};  var chart = new google.visualization.piechart(document.getelementbyid('nodes')); chart.draw(data, options);

}

jquery parses json data. output array of arrays.

here js example how works:

var json_data = "[[\"canada\", 66], [\"turkey\", 10], [\"hungary\", 23], [\"italy\", 49]]"; var parsed_data = $.parsejson(json_data);  document.write('<table><tr><th>city</th><th>number</th></tr>'); (var i=0; < parsed_data.length; i++) {     document.write('<tr><td>' + parsed_data[i][0] + '</td>');     document.write('<td>' + parsed_data[i][1] + '</td></tr>'); } document.write('</table>');

are sure since don't tell how retrieve data, sure jquery didn't parsed input json when retrieving it?

here jsfiddle link show contents of json_data

css - Text drops down with smaller window -

i've adapted css use in website , can't quite figure out why 1 aspect of page acting way acting. basically, when shrink window below size horizontally, of text "drops down". becomes issue if user viewing website through ipad vertical orientation. can view issue here . i'm hoping make if window gets smaller, placement of text remains intact. the problem area not have enough space put both side navigation , content on 1 line. make automatically adjust page's width when exceeds decrements of width. this code example, , highly unlikely work. if see css more clearly, provide exact code. @media , (max-width:960px) { /* assuming #wrapper 960px across */ #content {width:560px;} /* opposed 720px */ } edit the content drops down @ 980px, have shrink width after there. @media , (max-width:980px) { #container {width:520px;} }
