如何仅使用jquery检查指定的复选框?

标签: jquery checkbox uncheck

我有多个复选框。当我点击相应的按钮时,我想检查并取消选中其中一些或全部。

例如,当我点击“全部检查”按钮时,我想要检查所有按钮。当我点击“男性”按钮时,我只想检查“类”等于“男性”的复选框。当我点击“女性”按钮时,我只想检查类等于“女性”的复选框。当我点击“无”按钮时,我只想检查类等于“无”的复选框。我怎么能用jquery做到这一点?

<div>
<input type="checkbox" class="check_all"> Check all
<input type="checkbox" class="check_all_females"> Females
<input type="checkbox" class="check_all_males"> Males
<input type="checkbox" class="check_all_none"> None
</div>


<input type="checkbox" class='male'> John<BR>
<input type="checkbox" class='male'> Maria<BR>
<input type="checkbox" class='male'> Ali<BR>
<input type="checkbox" class='male'> Tural<BR>
<input type="checkbox" class='female'> John<BR>
<input type="checkbox" class='female'> Fuass<BR>
<input type="checkbox" class='female'> Jadsa<BR>
<input type="checkbox" class='none'> Dasda<BR>
<input type="checkbox" class='none'> Wers<BR>
<input type="checkbox" class='none'> Saqa<BR>

这样做:

$(function(){


 $("div.mains input:checkbox").click(function(){
    var rel = $(this).attr("rel"),
        checked = $(this).is(":checked");
    switch(rel)
    {
        case "all":
            if(!checked)
            {
                $(".sub input:checkbox").removeAttr("checked");
            }
            else
            {
                $(".sub input:checkbox").attr("checked", "checked");
            }
        break;
        default:
            if(!checked)
            {
                $(".sub input." + rel).removeAttr( "checked");
            }
            else
            {
                $(".sub input." + rel).attr( "checked", "checked");
            }

    }
});

});
