How to use modularization in layui
layui uses a modular approach: follow layui's module specifications to create an entry file, and load the entry file through the layui.use() method, such as [layui.use(['layer'], function(){var layer = layui.layer}].
The operating environment of this tutorial: Windows 10 system, layui version 2.5.6, this method is suitable for all brands Computer.
(Learning video sharing: javascript video tutorial)
Modular use:
Note: The introduced JS is:/layui/ layui.js
Follow layui's module specifications to create an entry file and load the entry file through layui.use()
Example:
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>模块化的使用</title>
<link rel="stylesheet" href="./layui/css/layui.css">
<!--引入这个JS-->
<script type="text/javascript" src="./layui/layui.js"></script>
</head>
<body>
<script>
/*必须使用这个方法先引用对应的模块*/
layui.use(['layer'],function () {
var layer = layui.layer;
layer.alert("xxxxxxxxxxxxxxxxxxxxxxxx")
})
</script>
</body>
</html>Additional: In order For convenience, you can use the following method to introduce
function deleteDictBatch(){
var form,layer;
layui.use(['form','layer'],function () {
form = layui.form;
layer=layui.layer;
});
//获取选中的元素的个数
var length_1 = $("[name='dictionaryCheckbox']:checked").length;
//1.如果选中的个数为0，直接退出函数，提示选择字典删除
if(length_1 ==0 ){
layer.alert("请选中需要删除的字典")
return ;
}
//如果有元素需要被删除
else{
if(!confirm("您确认要删除下列字典?")){//点取消也退出函数
return;
}
//第二种方式，以数组的方式去提交。后台用string接收
var values = [];
$("[name='dictionaryCheckbox']:checked").each(function (i) {//i代表索引
values[i]=$(this).val();
})
$.post(contextPath+'/dictionary/deleteDictBatch.do',{dictionaryIds:values.toString()},function(response){
alert(response);
if(response == "删除成功"){
getDictionaryTree();//查询字典树
getDictionaryFY();//分页查询字典信息
}
},'text')
//删除的业务逻辑
}
}, or you can introduce layer and form as global variables:
/**
* @author: qlq
* @time: 9:31
* @description: 添加培养方案的JS
*/
/**
* 一次性自调函数初始化两个全局变量
*/
var lyer,form;
(function () {
layui.use(['layer','form'],function () {
layer=layui.layer,form=layui.form;
})
})();
/**
* 页面加载完成后执行一些函数
*/
$(function () {
layer.msg("消息框")
});
