将多个 jQuery.val() 读入数组 [英] Read multiple jQuery.val() into array

问题描述

我有一些看起来像这样可以正常工作的代码:

I have some code that looks like this that works just fine:

var info = [];
for (i = 0; i < 10; i++)
{
     info[i] = $('#info_' + i).val();
}

问题是这种模式在我的应用程序中很常见，但有一些细微的变化.我想做的是把它变成一个像这样的单线器，其中信息变成一个数组:

The problem is that this pattern is very common in my application with some minor variations. What i would like to do is to make this into a oneliner something like this where info becomes an array:

var info = $('[id^="info_"]').each().val();

推荐答案

感谢 Dogbert.他的示例中缺少的只是 .get()

Found a solution thanks to Dogbert. All that was missing in his example was the .get()

这是我最终使用的解决方案:

Here is the solution i ended up using:

var info = $('[id^="info_"]').map(function () { return $(this).val(); }).get();
