遍历名称具有公共字符串的所有实例

问题描述

是否有一种方法可以访问以公共字符串开头的所有对象实例.

Is there a way to access all the object instances starting with a common string.

示例:我有名为button64，button223，button856471，button229846等的实例.我无法控制这些实例的命名方式.我想将所有这些都推送到一个数组中.

Example: I have instances named button64, button223, button856471, button229846, etc. I have no control over how these instances are named. I want to push all these in an array.

我不是在创建这些对象，我只需要编写一个JavaScript文件，该JavaScript文件位于此HTML页面中，并收集所有以字符串"button"开头的对象实例.

I am not creating these objects, I just have to write a javascript which sits in this HTML page and collects all the object instances starting with the string 'button'.

目的是从其中伸出一个想要的物体并改变视觉元素.

The purpose is to reach out to a desired object out of these and change the visual element.

此外，该解决方案必须与IE8兼容.关于如何迭代的任何想法?

Also, the solution has to be compatible with IE8. Any ideas about how should I iterate?

推荐答案

如果可以使用jQuery，则可以编写:

If you can use jQuery, you could write:

var buttonsArray = [];

$("div").each(function() {
    var id = $(this).attr("id");

    if (id && id.indexOf("button") == 0) {
        buttonsArray.push($(this));
    }
});
