ajax 使用实例(ajax每次使用都要上网查,记不住,这次写下来,下次来复制就好了)

前段代码

function rem(id,obj) {

$.ajax({
type:"post",
async:true,
url:"${ctx}/activity/hgRlzyActivity/deleteActidata?actidataId="+id,
dataType:"json",

success: function(data) {

                                        alert(data.success);

var i=obj.parentNode.parentNode.rowIndex;
        document.getElementById('Actidatatable').deleteRow(i);
$.jBox.alert("删除成功！");
$("#leth").val(Number($("#leth").val())-1);
},
error: function(data) {
$.jBox.alert("删除失败！");
}
})

}

后端代码

@RequiresPermissions("activity:hgRlzyActivity:edit")
@RequestMapping(value = "deleteActidata")
@ResponseBody//json必须
public JSONObject deleteActidata(String actidataId) {
JSONObject object=hgRlzyActivityService.deleteActidata(actidataId);
return object;
}
