我如何在后台连续运行ajax请求


How do I run ajax request in background continuously?

我希望在输入新数据时立即显示数据,但我不希望用户总是刷新页面以查看新数据。

You can use a php script to call ajax url like

$(function(){
  getAjaxRequest();
});
function getAjaxRequest(){
  $.ajax({
    url:"someurl.php",
    data:{data:"data"},
    success:function(result){
       //result retrieval queries
       //and
       setTimeout(getAjaxRequest,1000); //call the same function every 1s.
    },
    error:function(err){
       //error handler
    } 
  });
}
