取消选中所有其他复选框 [英] Uncheck all other checkboxes

问题描述

当用户点击复选框时，我需要清除所有其他复选框。与单选按钮几乎相同的行为。用户点击复选框A，复选框B和C都未选中。我使用jquery，但我不知道如何完成这个。任何想法？

I need to clear all other checkboxes when a user clicks a checkbox. Pretty much the same behavior as a radio button. User clicks checkbox 'A' and checkboxes 'B' and 'C' are both unchecked. I am using jquery but I can't figure out how to accomplish this. Any ideas?

这里是如何设置复选框u：

Here are how the checkboxes are set u:

    <div class="sales_block_one">
<span class="sales_box_option_set"><input type="checkbox" value="1" id="exopt10i11553501716" name="optset[0][id]" /><label for="exopt10i11553501716">Test  + &pound;100.00</label></span> 
<span class="sales_box_option_set"><input type="checkbox" value="2" id="exopt11i21553501716" name="optset[1][id]" /><label for="exopt11i21553501716">Test  + &pound; 200.00</label></span> 
<span class="sales_box_option_set"><input type="checkbox" value="3" id="exopt12i31553501716" name="optset[2][id]" /><label for="exopt12i31553501716">Test 3 + &pound;400.00</label></span> 
</div>

推荐答案

如果所有复选框都是兄弟姐妹， ，

if all the checkboxes are siblings, it's just like this,

$(':checkbox').change(function(){

   if (this.checked) {
      $(this).siblings(':checkbox').attr('checked',false);
   }

});

疯狂演示

好吧，如果你真的要复制单选按钮的行为，就像这样，

Well, if you really want to copy the behavior of the radio button, simple as this,

$(':checkbox').change(function(){
      this.checked = true;
      $(this).siblings(':checkbox').attr('checked',false);     
});

siblings是当元素具有相同的父级/容器时。

siblings is when the elements has one same parent/container.

示例

<div>

<input type="checkbox" /><label>A</label>
<input type="checkbox" /><label>B</label>
<input type="checkbox" /><label>C</label>
<input type="checkbox" />​<label>D</label>

</div>

其中，< input> 和< label> 是兄弟姐妹。

case这不是兄弟姐妹，你可以这样做，

In your case, which it's not siblings, you can do it this way,

$('.sales_block_one :checkbox').change(function() {
    var $self = this; // save the current object - checkbox that was clicked.
    $self.checked = true; // make the clicked checkbox checked no matter what.
    $($self).closest('span') // find the closest parent span...
        .siblings('span.sales_box_option_set') // get the siblings of the span
        .find(':checkbox').attr('checked',false); // then find the checbox inside each span and then uncheck it.
});​
