一、传数组
前端js:
$(document).on('click', '#sendArr', function () {
var ids = [];
for(var i=0; i<10; i++){
ids.push(i);
}
$.ajax({
type: 'post',
dataType: 'json',
url: '/test/test/sendArr',
data: {ids:ids},
traditional: true,
success: function (result) {
console.log(result)
},
error: function(data){
alert("操作异常");
}
});
});
或者
$(document).on('click', '#sendArr', function () {
var params = {
ids:[]
}
for(var i = 10; i > 0; i--) {
params.ids.push(i);
}
$.ajax({
type: 'post',
dataType: 'json',
url: '/test/test/sendArr',
data: params,
traditional: true,
success: function (result) {
console.log(result)
},
error: function(data){
alert("操作异常");
}
});
});
后端:
@PostMapping("/sendArr")
public Map<String,Object> sendArr(String[] ids) {
Map<String,Object> map = new HashMap<String,Object>();
map.put("ids", ids);
return map;
}
二、传list集合
前端js:
$("#sendList").click(function(){
var ids = [];
for(var i=0; i<10; i++){
ids[i] = i;
}
$.ajax({
type: 'post',
dataType: 'json',
url: '/test/test/sendList',
data: JSON.stringify(ids),
contentType:"application/json",
success: function (result) {
console.log(result)
},
error: function(data){
alert("操作异常");
}
});
});
后端:
@PostMapping("/sendList")
public Map<String,Object> sendList(@RequestBody List<String> ids) {
Map<String,Object> map = new HashMap<String,Object>();
map.put("ids", ids);
return map;
}
