javascript - 在 javascript 中，如何从对象数组中删除一个元素？

Question

在 javascript 中，如何从对象数组中删除一个元素？这是代码:

$.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!

参见 https://developer.mozilla.org/en/Core_JavaScript_1.5_Reference/Operators/Special_Operators/delete_Operator

例如(来自来源)

var trees = ["redwood","bay","cedar","oak","maple"];  
delete trees[3];  
if (3 in trees) {  
   // this does not get executed  
}
