javascript - 将多个 onclick 压缩为一个

Question

这是我当前的代码：

document.getElementsByName('links')[0].onclick = function (event) {
event = event || window.event;
var target = event.target || event.srcElement,
    link = target.src ? target.parentNode : target,
    options = {index: link, event: event},
    links = this.getElementsByTagName('a');
blueimp.Gallery(links, options);
};

document.getElementsByName('links')[1].onclick = function (event) {
event = event || window.event;
var target = event.target || event.srcElement,
    link = target.src ? target.parentNode : target,
    options = {index: link, event: event},
    links = this.getElementsByTagName('a');
blueimp.Gallery(links, options);
};

我意识到这种复制和粘贴非常低效（当我需要添加[2].onclick,[3].onclick等时只会变得更糟），那么有没有办法可以将它们全部压缩在一起？

我是 Javascript 的初学者，所以如果这个问题非常简单，请原谅我。

除了 jQuery，您需要做的就是封装重复的代码，例如：

<script>
var elements = document.getElementsByName('links');
Array.prototype.forEach.call(elements, function (el) {
    el.onclick = function (event) {
        event = event || window.event;
        var target = event.target || event.srcElement,
            link = target.src ? target.parentNode : target,
            options = {index: link, event: event},
            links = this.getElementsByTagName('a');
        blueimp.Gallery(links, options);
    };
});
</script>
