The effect of Jquery waiting for ajax to be executed before continuing to execute the following code. The specific code is as follows. In fact, it is to set the async parameter of the jquery ajax function to false. This parameter defaults to true:

$(document).ready(function(){ 
  loadphpernote(); 
  window.open('http://www.phpernote.com'); 
}); 
function loadphpernote(){ 
  var url='http://www.phpernote.com/ajax.php'; 
  var data='action=list'; 
  jQuery.ajax({ 
    type:'post', 
    url:url, 
    data:para, 
    async:false,//false代表只有在等待ajax执行完毕后才执行window.open('http://www.phpernote.com')语句 
    success:function (msg){ 
      $('#articleList').html(msg); 
    } 
  }); 
}

Let me introduce to you the jquery loading waiting effect

 var dates = this.options.form.getWidgetByName("dates").getValue(); 
 $.ajax({  
  url: "http://127.0.0.1:9009/Brilliantzz/service/snproduct.do",  
  data:dates, 
beforeSend:function() { 
   var h = document.body.clientHeight;  
 $("<div class=\"datagrid-mask\"></div>").css({display:"block",width:"100%",height:h}).appendTo("body");  
 $("<div class=\"datagrid-mask-msg\"></div>").html("正在上传生产数据，请稍候。。。").appendTo("body").css({display:"block", 
 left:($(document.body).outerWidth(true) - 190) / 2, 
 top:(h - 45) / 2}); 
  }, 
complete:function(data) { 
     $('.datagrid-mask-msg').remove(); 
  $('.datagrid-mask').remove(); 
  }, 
  success: function(data) { 
    alert("生产数据:"+data);   
  }, 
  error: function(data) { 
       alert("上传生产数据异常！"); 
      } 
    });
