最近在使用layui前端框架,在使用單選按鈕、下拉菜單select、checkbox等控件的時(shí)候,往往遇到一些初始化的東西,下面這篇文章主要給大家介紹了關(guān)于layui動(dòng)態(tài)設(shè)置單選按鈕選中效果的相關(guān)資料,需要的朋友可以參考下

很久沒用過layui框架了，最近在修改代碼時(shí)，遇到一個(gè)問題，就是怎么動(dòng)態(tài)設(shè)置選中單選按鈕。需求是根據(jù)后臺(tái)返回的數(shù)據(jù)中的性別（0和1）設(shè)置動(dòng)態(tài)選中性別單選按鈕。

效果圖如下：

前端頁(yè)面代碼如下：

<!DOCTYPE html>

后臺(tái)接口/admin/getLogin返回的數(shù)據(jù)格式為

{
?? ?"code": 200,
?? ?"data": {
?? ??? ?"id": 1,
?? ??? ?"name": "超級(jí)管理員",
?? ??? ?"gender": 0,
?? ??? ?"username": "admin",
?? ??? ?"password": "123456",
?? ??? ?"roleId": "11111",
?? ??? ?"head": "/admin/20220520004040.jpg",
?? ??? ?"phone": "18888888888",
?? ??? ?"email": "heyl_163_com@163.com",
?? ??? ?"birthDate": "2022-09-11",
?? ??? ?"unlockCode": "123456",
?? ??? ?"lastLoginTime": "2022-10-15 03:13:09"
?? ?}
}

userInfo.js文件的內(nèi)容：

let $, form, $form;
layui.config({
	base : "/js/"
}).use(['form', 'layer', 'laydate'],function(){
	let layer = (parent.layer === undefined) ? layui.layer : parent.layer, laydate = layui.laydate, upload = layui.upload;
	$ = layui.jquery;
	form = layui.form;
	$form = $('form');
	laydate.render({
		elem: '.birthDate'
	});
	$(".realName").attr("placeholder", "請(qǐng)輸入真實(shí)姓名");
	$(".phone").attr("placeholder", "請(qǐng)輸入手機(jī)號(hào)碼");
	$(".birthDate").attr("placeholder", "請(qǐng)輸入出生年月");
	$(".email").attr("placeholder", "請(qǐng)輸入郵箱");
	upload.render({
		elem: '#userFace',
		url: '/admin/upload',
		accept: 'file',
		done: function(res, index, upload) {
			$.get("/admin/getLogin", function(response) {
				$("#userFace").attr("src", response.data.head);
				layer.msg("頭像修改成功");
			}, 'json');
		},
		error: function(index, upload) {
			//請(qǐng)求異?；卣{(diào)
		}
	});
	$.get("/admin/getLogin", function(response) {
		let result = response.data;
		$(".email").val(result.email);
		$(".phone").val(result.phone);
		$(".realName").val(result.name);
		$(".username").val(result.username);
		$(".birthDate").val(result.birthDate);
		$("#userFace").attr("src", result.head);
		$("input:radio[value='" + result.gender +"']").prop("checked", true);
	}, 'json');
    // 提交個(gè)人資料
    form.on('submit(save)', function() {
    	let index = layer.msg('提交中，請(qǐng)稍候',{
    		icon: 16,
    		shade: 0.8,
    		time: false
    	});
    	let data = form.val("form");
    	$.post("/admin/updateById", data, function(response) {
  			if(response.code === 200) {
  				setTimeout(function(){
  					layer.close(index);
  	  				layer.msg(response.message);
  		        }, 2000);
  			} else {
  				layer.alert(response.message, {
  					icon: 2
  				});
  			}
  		}, 'json');
	});
});

看代碼好像沒有什么問題，但是實(shí)際運(yùn)行卻不會(huì)選中，選擇器也正確獲取到了，這個(gè)問題找了很久，幾番周折，最后才發(fā)現(xiàn)原來是忘記了重新渲染表單，將以上代碼的ajax請(qǐng)求部分修改為以下代碼即可。

$.get("/admin/getLogin", function(response) {
   let result = response.data;
   $(".email").val(result.email);
   $(".phone").val(result.phone);
   $(".realName").val(result.name);
   $(".username").val(result.username);
   $(".birthDate").val(result.birthDate);
   $("#userFace").attr("src", result.head);
   $("input:radio[value='" + result.gender +"']").prop("checked", true);
   form.render(); // 新增的的表單渲染代碼
}, 'json');

后面嘗試了很多次，發(fā)現(xiàn)以下幾種方法均可設(shè)置單選按鈕選中

$("input:radio[value='" + result.gender +"']").prop("checked", true);
$("input:radio[value='" + result.gender +"']").attr("checked", true);
$("input:radio[value='" + result.gender +"']").prop("checked", "true");
$("input:radio[value='" + result.gender +"']").attr("checked", "true");
$("input:radio[value='" + result.gender +"']").prop("checked", "checked");
$("input:radio[value='" + result.gender +"']").attr("checked", "checked");

此外，layui給我們提供了一個(gè)非常簡(jiǎn)單的方法來設(shè)置表單的值，可以通過表單元素的name屬性給表單全部元素賦值

$.get("/admin/getLogin", function(response) {
   let result = response.data;

   form.val("form", {
      "name": result.name,
      "phone": result.phone,
      "email": result.email,
      "gender": result.gender,
      "username": result.username,
      "birthDate": result.birthDate
   });
}, 'json');
