SpringBoot+Jquery+DataTables实现select改变数据联动加载（前后端全流程）
场景
效果
实现
html页面代码
页面使用的是thymeleaf模板。
下拉框代码：
input框代码：
dataTables代码：
货位编号
货位类型
物料类型
物料状态
所在货架
备注
Jquery代码
$(document).ready(function() {
//选择退货方后退货目的地绑定联动
$("#businessInitiator").bind("change", function () {
//获取选中的option的value值
var selected = $("#businessInitiator option:selected").val();
//获取退货目的地Input对象
var destination = $("#destination");
switch (selected){
case '原料立库':
destination.val("原料立库退货点")
break;
case '清洁车间':
destination.val("清洁车间退货点")
break;
case '正极车间':
destination.val("正极车间退货点")
break;
case '负极车间':
destination.val("负极车间退货点")
break;
default:
destination.val("其它退货点")
}
//退货目的地联动完成
// DataTable初始化
$("#example").dataTable().fnDestroy();//还原初始化了datatable
var t = $('#example').DataTable({

"targets": 0,
"bSortable": false,
"render": function(data, type, row, meta) {
if (row.isSelected == 1){
return ''
}
return ''
}
}],
"ajax": function (data, callback, setting) {
data.editActionId = $("#refundOrderId").val();
data.selected=selected;
$.ajax({
type: 'POST',
url: "/busGoodsLocation/getRejectsLocationsList",
cache: false, //禁用缓存
//async: true,
data: JSON.stringify(data), //传入组装的参数
contentType: "application/json",
dataType: "json",
success: function (result) {
callback(result);
}
})
}
});
});
});注：
1.页面加载完成后绑定下拉框 select的change事件，获取选中的option的值，通过case进行比较，进而给input进行赋值。
2.然后要还原一次dataTables的初始化，执行初始化的dataTables的初始化并请求数据。
3.将selected作为选中的值进行请求数据的参数，进而后台根据传递的值查询并返回不同的数据。
