Question

我在php中创建了一个数组（作为ajax响应的一部分）。我现在想将此数组转换为javascript对象数组。我该怎么办呢？

我的php数组（请不要这是wordpress php）：

$fortot2 = 5;
$fortot3 = 2;

if (is_numeric($numwelds) && is_numeric($numconwelds))
{
    $total['tot1'] = $numwelds + $numconwelds + $mpcountrys ;
    $total['tot2'] = $numwelds + $numconwelds + $fortot2 ;
    $total['tot3'] = ($numwelds + $numconwelds) + $fortot2 / $fortot3; 
    $response = json_encode($total);
    header("Content-Type: application/json");  
    echo $response;

现在，一旦json被编码，如何将其转换为javascript对象数组？

Answer 1

// responseData is fetched via Ajax-Get
var obj = jQuery.parseJSON(responseData);
alert(obj.property);

// full ajax example
jQuery.ajax({
    url: "/index.php?action=whereMyDataIs", // here php gives the json response
    type: "GET",
    dataType: "json",
    async: false,
    success: function (data) {
        console.log(data);
        alert(JSON.stringify(data));
    }
});

你已经拥有PHP部分（数组是构建，json_encoded并作为响应发送），下一步是通过对提供响应的PHP脚本执行ajax get请求，在客户端获取此json_response。通过指定dataType：＆＃34; json＆＃34;你告诉jQuery自动将传入的数据解析为Object Notation。如果要再次输出，例如有警报，你需要再次对其进行字符串化。

回答有关amcharts的问题：

// add the loadJson function to AmCharts
// but you could also use jQuery as demonstrated above
AmCharts.loadJSON = function(url) {
  // create the request
  if (window.XMLHttpRequest) {
    // IE7+, Firefox, Chrome, Opera, Safari
    var request = new XMLHttpRequest();
  } else {
    // code for IE6, IE5
    var request = new ActiveXObject('Microsoft.XMLHTTP');
  }

  // load it
  // the last "false" parameter ensures that our code will wait before the
  // data is loaded
  request.open('GET', url, false);
  request.send();

  // parse adn return the output
  return eval(request.responseText);
};

// init chart library
var chart;

// lets build that chart
AmCharts.ready(function() {

   // load the data from your php script (the json response)
   var chartData = AmCharts.loadJSON('script.php');

   // verify in browser console, if the data is loaded and parsed correctly
   console.log(chartData);

   // build the chart
   // ...

   // output the chart
   chart.write("chartdiv");
   });

如何将此php数组转换为JavaScript数组对象？
