javascript - 将 JSON 值合并到变量或字符串中

Question

我的 JSON 节点具有相同的标题，但每个节点中的纬度和经度值不同。我需要检查相同的标题值，然后将纬度和经度值合并到 map API 的 url 中。我需要它按纬度、经度、纬度、经度等顺序排列...我只是不知道此时该怎么办。感谢您的帮助或建议。

JS VAR

<img class="detail_map" src="http://open.mapquestapi.com/staticmap/v4/getplacemap?size=320,240&zoom=15&location=' + data.nodes.Latitude + ',' + data.nodes.Longitude + '&imagetype=jpeg&showicon=blue-1">

JSON 对象

var data = fl({
"nodes":[
    {"node":{
        "title":"180","Address":"555 Market St. San Francisco, CA United States See map: Google Maps","
        Latitude":"37.789952","
        Longitude":"-122.400158"}},
    {"node":{
        "title":"180","Address":"Epic Roasthouse (399 Embarcadero) San Francisco, CA United States See map: Google Maps","
        Latitude":"37.797677","
        Longitude":"-122.394339"}},
    {"node":{
        "title":"180","Address":"Mason & California Streets (Nob Hill) San Francisco, CA United States See map: Google Maps","
        Latitude":"37.791556","
        Longitude":"-122.410766"}},
    {"node":{
        "title":"180","Address":"Justin Herman Plaza San Francisco, CA United States See map: Google Maps","
        Latitude":"37.774930","
        Longitude":"-122.419416"}},
    {"node":{
        "title":"180","Address":"200 block Market Street San Francisco, CA United States See map: Google Maps","
        Latitude":"37.793133","
        Longitude":"-122.396560"}} 
]});

});

您可以使用$.extend()合并两个对象的函数，不同的属性将被替换。

示例:

var newData = $.extend(data1, data2);
// Assuming data1, data2 are objects;

如果需要将字符串 JSON 转换为对象，请使用 $.parseJSON()
