Getting id of checkboxes selected using jquery
提问by marchemike
I'm trying to get the id's of the checkboxes with the class file-selection-id. The checkbox is inside a for loop which is why I have placed variables on the id's and names.
我正在尝试使用 class 获取复选框的 ID file-selection-id。复选框位于 for 循环内，这就是为什么我在 id 和名称上放置变量的原因。
<input class="file-selection-id" type="checkbox" value="" name="file<?php echo $i; ?>_<?php echo $t; ?>" id="file<?php echo $i; ?>_<?php echo $t; ?>">
What I want is that when I click a button, it would get all of the id's of the selected checkboxes.
我想要的是，当我单击一个按钮时，它会获得所选复选框的所有 ID。
$('.move-file-buttons').click(
function(event) {
//???
$('input:checkbox.file-selection-id').each(function () {
});
});
But I don't know how to get the Id's of all the checkboxes that were on the file-selection-id class that I need? What could be ways on how I could call the ID's of the checkboxes(for example if I had 4 checkboxes with 2 selections)?
但我不知道如何获取我需要的文件选择 ID 类中所有复选框的 ID？我可以如何调用复选框的 ID（例如，如果我有 4 个带有 2 个选项的复选框）？

Use .map
使用.map
var arr = $('input:checkbox.file-selection-id').map(function () {
return this.id;
}).get();
如果你想要
idid的checkedchecked的复选框var arr = $('input:checkbox.file-selection-id').filter(':checked').map(function () {
return this.id;
}).get();
var arr = $('input:checkbox.file-selection-id:checked').map(function () {
return this.id;
}).get();
.filter()。筛选（）
