在javascript中，如何从对象数组中删除元素？
以下是代码：

In javascript, how do I remove an element from an array of objects? Here is the code:

$.fn.mapImage.deletePinpoint = function(image, pinpoint){
    var deleted = false;
    for (var i = 0; i < image.pinpoints.length; i++) {
        if(image.pinpoints[i].position == pinpoint.position){
            image.pinpoints.remove(i);
            deleted = true;
        }
        if(deleted){
            image.pinpoints[i].position -= 1;
        }
    }
    $('.edit-mode').find('div.dynamic-pinpoint-area').remove();
    $('.edit-mode').find('div.pinpoint-text').remove();
    $('.create-mode').find('div.static-pinpoint-area').remove();
    $('.create-mode').find('div.pinpoint-text').remove();

    $.fn.mapImage.load(image);

}

image.pinpoints 是对象数组。再次感谢大家！

image.pinpoints is the array of objects. Thanks again guys!

推荐答案

.splice 是w3schools给出的方法.com http://www.w3schools.com/jsref/jsref_splice.asp
要从索引x的数组中删除一个元素，你将拥有 trees.splice（x，x + 1）; 这将删除x并在需要时返回它。

.splice is the method given at w3schools.com http://www.w3schools.com/jsref/jsref_splice.asp To remove one element from an array with index x you would have trees.splice(x,x+1); This removes x and returns it if you need it.
