javascript - How can i pass a JSON array from php to JS? -


im trying populate morris.js chart set of results. in controller create array of results , use json_encode create json array, here output in view using print_r: 

{"positive":7,"negative":26,"pending":786,"contact clinic":242,"misc":2}

how pass morris.js chart populate chart using data label / value pairs? try either blank chart or "undefined" variable or "nan". here controller:

function execute_search() {     // retrieve posted search term.     $search_term = $this->input->post('search');      // results count , pass json:     $data = $this->search_model->count_res('$p_results_data');     $pos = 0; $neg= 0; $pen = 0; $cont = 0; $misc = 0;     foreach ($data $item) {         if ($item['result'] === 'positive') {             $pos++;         } elseif ($item['result'] === 'negative') {             $neg++;         } elseif ($item['result'] === 'pending') {             $pen++;         } elseif ($item['result'] === 'contact clinic') {             $cont++;         } else {             $misc++;         }     }     $res = array("positive"=>$pos, "negative"=>$neg, "pending"=>$pen, "contact clinic"=>$cont, "misc"=>$misc);     $data = json_encode($res);      // use model retrieve results:     $this->data['results'] = $this->search_model->get_results($search_term);     $this->data['chart'] = $data;     $this->data['totals'] = $this->search_model->total_res('$total_res');      // pass results view.     $this->data['subview'] = ('user/search_results');     $this->load->view('_layout_admin', $this->data); }

and morris.js:

$results = "<?php echo $chart ?>"; new morris.donut({     element: 'donuteg',     data: [         $results     ], });

any appreciated

in javascript, json.parse friend, assuming have json created php's json_encode function:

$results = "<?php echo $chart ?>"; new morris.donut({     element: 'donuteg',     data: [         json.parse( $results )     ], });

or possibly

$results = "<?php echo $chart ?>"; new morris.donut({     element: 'donuteg',     data: json.parse( $results ) });

but way it

in view:

<input type="hidden" id="chartdata" value='<?php echo $chart; ?>' />

in js (using jquery):

var chartdata = $('#chartdata').val(); new morris.donut({     element: 'donuteg',     data: json.parse( chartdata ) });

after looking @ documentation morris.js, found how can right way:

// looking @ docs morris.js: // http://jsbin.com/ukaxod/144/embed?js,output  // data, it's in 1 json object var chartdata = json.parse( $('#chartdata').val() );  // need break object parts of donut var donutparts = []; $.each( chartdata, function(k,v){     donutparts.push({         label: k,         value: v     }); });  // create donut morris.donut({     element: 'donuteg',     data: donutparts });
