layui code

$(function(){
 
layui.use('form', function(){
    var form = layui.form;
    form.on("checkbox(allCheck)", function(data){
        console.log(data);
        console.log(data.elem.checked);
        if (data.elem.checked) {
            //动态设置全选按钮颜色，不可以这里设置，这里设置后，前端选然后不会有效果的，
            //猜测原因是，form.render("checkbox"); 导致的，设置后layui又渲染了，把我自己设置的颜色覆盖了。所以设置需要在渲染后再设置，就等于是用我的css覆盖了layui的css
            $(".campus").each(function(){
                $(this).prop('checked', true);
            });
        } else {
            $(".campus").each(function(){
                $(this).prop('checked',  false);
            });
        }
        form.render("checkbox");
       //渲染后设置我的颜色
        allCheckbox();
    });
 
    //查看是否被全选了，全选了，全选按钮编辑的时候就是被选中中状态
    function initselect(){
        let allSelect = true;
        $(".campus").each(function(index, elem){
            //每个checkbox添加点击事件，如果点击了，使得所有的按钮中出现了不被选中的，那么全选按钮就不被选中
            if($(this).prop('checked') == false){
                allSelect = false;<br>               
            }
        });
        console.log("是否全选",allSelect)
        $("#qx").prop(&#39;checked&#39;,allSelect);
        form.render("checkbox");
        //记得把设置事件放到渲染事件后
        allCheckbox();
    }
    initselect();
 
    //校区点击事件，如果有校区没有被选中，那么全选按钮就不能够显示选中状态
    form.on("checkbox(campus)", function(data){
        let checked = data.elem.checked;
        initselect();
    });
 
});
 
    //全选按钮和其他按钮的颜色不一样
    function allCheckbox(){
        qx1=$(&#39;#qx&#39;).next(&#39;div&#39;).children(&#39;span&#39;);
        if($(&#39;#qx&#39;).prop(&#39;checked&#39;)){
            //被选中就设置颜色
            qx1.css({
                &#39;background-color&#39;:&#39;#e4393c&#39;
            })
        }
    }
    //初始化设置全选按钮的颜色，
    allCheckbox();<br><br>})
