Question

我无法将从ajax调用获得的值赋给数组并传递该数组。

所以变量选项无效

我有这段代码

$.ajax({ url: url,
    success: function(data){
        for (var i = 0; i < data.length; i++) {
            var object =  data[i];
            var array = JSON.parse(object.polygon);
            var options = {
                 color: object.color, 
                 fillColor: object.fill, 
                 fillOpacity: object.opacity
             };

            var options_example = {
                 color: "#fff", 
                 fillColor: "#000", 
                 fillOpacity: "0.7"
             };

            console.log(options);// This Print correctly
            console.log(options_example);// same as previous one

            var land = L.polygon(array,options).addTo(map);//Not Work
            var land = L.polygon(array,options_example).addTo(map);//Working
            land.bindPopup("<b>"+object.number+"</b><br>"+object.area);

        }
    }});

响应：

[{"id":"2","number":"asd","area":"asd","polygon":"[[32.31948848454971,35.31074523925781],[32.33022285080643,35.32121658325195],[32.318908212283944,35.360355377197266],[32.29743552506946,35.30954360961914],[32.31948848454971,35.31074523925781]]","basin":"asd","color":""},{"id":"7","number":"adasd","area":"asd","polygon":"[[32.32129727814492,35.36873459815979],[32.321542074502524,35.36865413188934],[32.32107061426081,35.36771535873413],[32.32083488321952,35.368616580963135],[32.32129727814492,35.36893308162689],[32.32134714412331,35.36882042884826],[32.32129727814492,35.36873459815979]]","basin":"asdas","color":"#fff","fill":"#000","opacity":"0.7"}]

我不知道我在这里缺少什么

在响应对象的数组的第一个元素中，字段fillColor和fillOpacity以及color为空。

也许尝试一些默认的vaules：

var options = {
             color: object.color || "#fff", 
             fillColor: object.fill || "#000", 
             fillOpacity: object.opacity || "0.7"
         };

将值从Ajax分配给Array
