Layui's method of listening to multiple radio events

The requirements are as follows: If you want to select radio button 3, select all the check boxes under radio button 3

If there is not much information in the panel, you can add a fixed listening event to each radio button 3

But in the actual project, there are not only two, but dozens. At this time, you can never bind Define a lay-filter and add a form.on('radio(filter)') event

So here I wrote a general method for monitoring multiple radios:

// 选取“单选框3”，“单选框3”下的所有内容全选
        var flagID = document.querySelectorAll("input[title='单选框3']");
        var aFlagID = new Array();
        for (var j = 0; j < flagID.length; j++) {
            aFlagID.push(flagID[j].id);
        }
        // 监听所有title为“单选框3”的radio
        // 注意：此时title为“单选框3”的radio的id和lay-filter需要设为一致！！！！
        for (var i = 0; i < aFlagID.length; i++) {
             form.on(&#39;radio(&#39;+aFlagID[i]+&#39;)&#39;, function(data) {
                $(data.elem).next().next().children("input").addClass(""+aFlagID[i]+"_other");
                $("."+aFlagID[i]+"_other").attr("checked", "checked");
                $("."+aFlagID[i]+"_other + div").addClass(&#39;layui-form-checked&#39;);
                element.init();
            });
        }

This Here, the lay-filter of each radio is obtained through the id, and the radio id and lay-filter are set to be the same;

$(data.elem) is the currently monitored DOM element; please note here Look at the page that has been successfully rendered by the browser;

The input element is selected at this time, which is radio button 3, but because layui beautifies the input, the input is not displayed;

Pay attention to the picture below: at this time, the next element of input is the "radio button 3" we see

Be sure to look for it when selecting the element Quasi-element!

This method has the following limitations:

1. You need to manually set the id and lay-filter for each "radio button 3";

2. "Radio button 3" The id and lay-filter of "Box 3" need to be consistent;

3. When obtaining elements, the jQuery method is used to find elements;

4. The method of finding elements needs to be changed according to different page layouts.
