User.find(distribution.assignee_id).full_name : " " %> </td> <td> <%= distribution.comments %> </td> </tr> <% end %> </table><% end %> 解决方案 Here's a working example for you: http://jsfiddle.net/wYPWL/HTML example:<input type="checkbox" id="selectAll" value="selectAll"> Select / Deselect All<br/><br/><input type="checkbox" name="foo" value="bar1"> Bar 1<br/><input type="checkbox" name="foo" value="bar2"> Bar 2<br/><input type="checkbox" name="foo" value="bar3"> Bar 3<br/><input type="checkbox" name="foo" value="bar4"> Bar 4<br/>Javascript:$('#selectAll').click(function() { if (this.checked) { $(':checkbox').each(function() { this.checked = true; }); } else { $(':checkbox').each(function() { this.checked = false; }); }});This will work regardless of what your checkboxes are named. If you really wanted to target only your checkboxes shown in your code above, you can replace $(':checkbox') with $('input[id^="distribution_ids"]') which is jQuery's way of targeting input elements that have an ID that starts with distribution_ids 这篇关于在页面中选择全部/取消选择所有复选框的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！ 上岸，阿里云！
