我希望this 可以工作
HTML
A <input type="checkbox" class="alpha" value="A" /> |
B <input type="checkbox" class="alpha" value="B" /> |
C <input type="checkbox" class="alpha" value="C" />
<br />
1 <input type="checkbox" class="num" value="1" /> |
2 <input type="checkbox" class="num" value="2" /> |
3 <input type="checkbox" class="num" value="3" />
JavaScript
// include jQuery library
var enforeMutualExcludedCheckBox = function(group){
return function() {
var isChecked= $(this).prop("checked");
$(group).prop("checked", false);
$(this).prop("checked", isChecked);
}
};
$(".alpha").click(enforeMutualExcludedCheckBox(".alpha"));
$(".num").click(enforeMutualExcludedCheckBox(".num"));
好吧,单选按钮应该是在相互排除的选项中使用的那个,尽管我遇到了这样一种情况,即客户端希望选择零到一个项目,并且 javaScript 的复选框效果很好。
更新
看着我的回答,我意识到两次引用 css 类是多余的。我更新了我的代码以将其转换为 jquery 插件,并根据个人喜好创建了两个解决方案
获取检查被相互排除的所有复选框
$.fn.mutuallyExcludedCheckBoxes = function(){
var $checkboxes = this; // refers to selected checkboxes
$checkboxes.click(function() {
var $this = $(this),
isChecked = $this.prop("checked");
$checkboxes.prop("checked", false);
$this.prop("checked", isChecked);
});
};
// more elegant, just invoke the plugin
$("[name=alpha]").mutuallyExcludedCheckBoxes();
$("[name=num]").mutuallyExcludedCheckBoxes();
HTML
A <input type="checkbox" name="alpha" value="A" /> |
B <input type="checkbox" name="alpha" value="B" /> |
C <input type="checkbox" name="alpha" value="C" />
<br />
1 <input type="checkbox" name="num" value="1" /> |
2 <input type="checkbox" name="num" value="2" /> |
3 <input type="checkbox" name="num" value="3" />
sample code
将所有相互排除的复选框分组到包含元素中
JavaScript
$.fn.mutuallyExcludedCheckBoxes = function(){
var $checkboxes = this.find("input[type=checkbox]");
$checkboxes.click(function() {
var $this = $(this),
isChecked = $this.prop("checked");
$checkboxes.prop("checked", false);
$this.prop("checked", isChecked);
});
};
// select the containing element, then trigger the plugin
// to set all checkboxes in the containing element mutually
// excluded
$(".alpha").mutuallyExcludedCheckBoxes();
$(".num").mutuallyExcludedCheckBoxes();
HTML
<div class="alpha">
A <input type="checkbox" value="A" /> |
B <input type="checkbox" value="B" /> |
C <input type="checkbox" value="C" />
</div>
<div class="num">
1 <input type="checkbox" value="1" /> |
2 <input type="checkbox" value="2" /> |
3 <input type="checkbox" value="3" />
</div>
