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('radio('+aFlagID[i]+')', function(data) { $(data.elem).next().next().children("input").addClass(""+aFlagID[i]+"_other"); $("."+aFlagID[i]+"_other").attr("checked", "checked"); $("."+aFlagID[i]+"_other + div").addClass('layui-form-checked'); 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.
