Javascript Jquery复选框max checked

Javascript Jquery复选框max checked,javascript,php,jquery,Javascript,Php,Jquery,由于某些原因,我的代码不能正常工作,当长度>5时,它应该禁用复选框。这是我的密码: <script type="text/javascript"> var $checks = $(".bowling").change(function () { if ($checks.filter(":checked").length<=5) { $(".formular").toggle($checks.filter(":che

由于某些原因,我的代码不能正常工作,当长度>5时,它应该禁用复选框。这是我的密码:

<script type="text/javascript">
    var $checks = $(".bowling").change(function () {
        if ($checks.filter(":checked").length<=5)
        {
            $(".formular").toggle($checks.filter(":checked").length>0);
            $("html, body").animate({scrollTop: $(".formular").offset().top});
        }
        else
        {
            $checks.filter(":checked").attr("disabled", "disabled");
        }
    });
</script>

var$checks=$(“.bowling”).change(函数(){
如果($checks.filter(“:checked”).length0);
$(“html,body”).animate({scrollTop:$(“.formular”).offset().top});
}
其他的
{
$checks.filter(“:checked”).attr(“禁用”、“禁用”);
}
});
html它在一段时间内:

<label class="ora_bg" data-toggle="tooltip" data-trigger="click hover" data-placement="bottom" >    
    <input class="bowling" type="checkbox" value="'.$row['Interval'].'" name="interval[]" class="checkbox" id="i'.$row['Interval'].'">
    <h3 class="ora2_bg">'.$row['Interval'].'</h3>
</label>

“.$row['Interval']”
var$checks=$(“.bowling”).change(函数(){

如果($checks.filter(“:checked”).length这对我在JSFIDLE上的工作很好:

<input class="bowling checkbox" type="checkbox" value="" type="checkbox" />
<input class="bowling checkbox" type="checkbox" value="" type="checkbox" />
<input class="bowling checkbox" type="checkbox" value="" type="checkbox" />
<input class="bowling checkbox" type="checkbox" value="" type="checkbox" />
<input class="bowling checkbox" type="checkbox" value="" type="checkbox" />
<input class="bowling checkbox" type="checkbox" value="" type="checkbox" />
<input class="bowling checkbox" type="checkbox" value="" type="checkbox" />


$(document).ready(function(){    // I have just added this
    var $checks = $(".bowling").change(function () {
        if ($checks.filter(":checked").length<=5)
        {

            $checks.not(":checked").removeAttr("disabled");
            $("html, body").animate({scrollTop: $(".formular").offset().top});
        }
        else
        {
            $checks.not(":checked").attr("disabled", "disabled");
        }
    });
});

$(document).ready(function(){//我刚刚添加了这个
var$checks=$(“.bowling”).change(函数(){
if($checks.filter(“:checked”).length
var$checks=$(“.bowling”).change(函数(){
如果($checks.filter(“:checked”)。长度<5)
{
$(“.formular”).toggle($checks.filter(“:checked”).length>0);
//启用所有输入
$checks.not(“:checked”).removeAttr(“disabled”);
}
其他的
{
$checks.not(“:checked”).attr(“disabled”、“disabled”);
}
});
这对我来说很好


在这里,由于您没有提供标记,我已经为您创建了一个可能满足您的需求的虚拟示例

$(函数(){
$(“输入[type='checkbox']”)。在('click',function()上{
警报($(“输入:复选框:未(:选中)”).length;
如果($(“输入:复选框:未(:选中)”)。长度0)
{
var value=checked.val();
$(“输入[name='banners\u image\u local']”)val(值);
}
}     
});
});

是否删除了文档准备处理程序以缩短示例?如果没有,则需要一个.lenght of unchecked复选框为5或选中?使用.prop()设置选中状态,如
$checks.filter(:checked”).prop(“disabled”,true);
当选中长度=5时,在复选框更改事件中,然后将禁用属性添加到所有未选中的复选框中。似乎。不是获胜答案:d,thnx是working@user3058067,很高兴帮助你。嗯,但这是一个错误,在我取消选中一个复选框后,我无法再选中另一个:-?我已经为你创建了一个虚拟示例,只需选中down@user3058067,我就可以了已更新我的答案。请检查。
