jQuery. How to uncheck all checkboxes except one (which was checked)
提问by Andrew
I have html items, 4 example:
我有 html 项目，4 个示例：
<div>
<div><input type="checkbox" class="foo"> Checkbox</div>
<div><input type="checkbox" class="foo"> Checkbox</div>
<div><input type="checkbox" class="foo"> Checkbox</div>
<div><input type="checkbox" class="foo"> Checkbox</div>
<div><input type="checkbox" class="foo"> Checkbox</div>
<div><input type="checkbox" class="foo"> Checkbox</div>
</div>
And now, I want next: If I click on any checkbox - the checkbox should be checked and other checkboxes should be unchecked. How can I do it?
现在，我想要下一个：如果我点击任何复选框 - 应该选中该复选框，并且应该取消选中其他复选框。我该怎么做？

You can use radiobutton and group them by name attributes. If you have to do it with checkboxesthen you can do it this way,
您可以使用radio按钮并按名称属性对它们进行分组。如果你必须这样做，checkboxes那么你可以这样做，
$('.foo').click(function(){
$('.foo').attr('checked', false);
$(this).attr('checked', true);
});
For dynamically generated html you need onthat allows you to delegate the event with static parent, you can use document with you do not know static parent.
对于动态生成的html你需要的，让您与委托父母静态的情况下，你可以使用文档与您不知道静的父母。
$(document).on('click','.foo', function(){
$('.foo').attr('checked', false);
$(this).attr('checked', true);
});
Document could be replaced by static parent if it is known. e.g. if div contain dynamically generated has id parentdivthen you can have
如果已知，文档可以被静态父级替换。例如，如果 div 包含动态生成的 has idparentdiv那么你可以拥有
`$('#parentdiv').on('click','.foo', function(){`

Use propinstead of attrfor properties checked, selected, or disabledas per documentation.
使用prop的，而不是attr对性能checked，selected或disabled按文档。
As of jQuery 1.6, the .attr() method returns undefined for attributes that have not been set. To retrieve and change DOM properties such as the checked, selected, or disabled state of form elements, use the .prop() method.
从 jQuery 1.6 开始，.attr() 方法为尚未设置的属性返回 undefined。要检索和更改 DOM 属性，例如表单元素的选中、选中或禁用状态，请使用 .prop() 方法。

Maybe this will help you:
也许这会帮助你：
.siblings("input[type='checkbox']").attr("checked", true);
will select all the checkboxes except for the one that was clicked.
将选中除被单击的复选框之外的所有复选框。
$("input[type=checkbox]").on("click", function() {
if ($(this).val() == "none") {
$(this).siblings("input[type=checkbox]").attr('checked', false);
} else {
$(this).siblings("input[value=none]").attr('checked', false);
}
