Javascript数组对象需要删除元素

Question

Google map directionsService.route 需要使用 javascript 添加删除 waypoint。

可以使用代码向数组添加新点:

waypts.push({ location: "Rome, Italy", stopover: true });

从数组中删除航路点时出现问题

Here my some data example that can explain more brief;

Need to remove point 1 or point 2 from above javascript object array how do it possible.

Then I will create new waypts for each time route draw from above array named nwaypts.

var nwaypts = [
{ location: "Rome, Italy", stopover: true }, // xyz: start point 
{ location:  { lat: 42.2070007, lng: 12.48549939999998 }, stopover: true, id: "17167" }, // point 1
{ location: { lat: 42.3793831, lng: 12.82857039999999 }, stopover: true, id: "18823" }, // point 2
{ location: "Terni, Italy", stopover: true } // xyz: end point 
];

您好，在删除航点中，您可以将 id 添加到标记，然后在 removecode 期间，您可以尝试与标记 id(您想要删除的)进行比较。请提供完整代码以获得确切的解决方案。

var nwaypts=[];
                        var j=0;
                        for ( var i = 0; i < waypts.length ; i++) {
                            if(waypts[i].id!=removemarkerid){
                                nwaypts[j]=waypts[i];
                                j++;
                            }
                        }
                        waypts=nwaypts;
