javascript - 如何将字符串转换为javascript数组

Question

我有这个字符串

[['Kaufen Kaufen', 11.6024872, 50.96389749999999, 1], ['Demandware', -71.13296849999999, 42.4884618, 2],['Downtown TV Shop', -71.0661193, 42.3548561, 3], ['Electronics Super Store', -73.21165839999999, 41.1687117, 4],['Super Electronics', -71.40915629999999, 41.816736, 5]]

它已经是数组形式，但它是字符串，我想将其转换为javascript数组，因为我遇到了谷歌地图在谷歌地图中显示图钉的问题。

var locations = 'javascript array here';
var map = new google.maps.Map(document.getElementById('map'), {
                      zoom: 10,
                      center: new google.maps.LatLng(11.60, 50.96),
                      mapTypeId: google.maps.MapTypeId.ROADMAP
                    });

                    var infowindow = new google.maps.InfoWindow();

                    var marker, i;

                    for (i = 0; i < locations.length; i++) {  
                      marker = new google.maps.Marker({
                        position: new google.maps.LatLng(locations[i][1], locations[i][2]),
                        map: map
                      });

                      google.maps.event.addListener(marker, 'click', (function(marker, i) {
                        return function() {
                          infowindow.setContent(locations[i][0]);
                          infowindow.open(map, marker);
                        }
                      })(marker, i));
                    }

您可以使用JSON.parse将JSON转换为JS对象/数组。现在的问题是，您的字符串有单引号'，而 JSON.parse 需要双引号，因此您必须替换它。

另一种情况是，字符串本身可以有单引号。对于这种情况，您应该检查其后面是否没有任何字符。

为了描述这种情况，我已将您的字符串更新为 'Kaufen Kaufe'n'

示例

var str="[['Kaufen Kaufe'n', 11.6024872, 50.96389749999999, 1], ['Demandware', -71.13296849999999, 42.4884618, 2],['Downtown TV Shop', -71.0661193, 42.3548561, 3], ['Electronics Super Store', -73.21165839999999, 41.1687117, 4],['Super Electronics', -71.40915629999999, 41.816736, 5]]";
console.log(JSON.parse(str.replace(/'(?![a-z])/g, '"')));
