This time I will show you how to avoid being intercepted by the browser when opening a new form with ajax callback. How to avoid being intercepted by the browser when opening a new form with ajax callback. What are the precautions?. Here is the actual combat. Let’s take a look at the case.
ajax callback opens a new form to prevent browser interception, just do this!
Problem analysis:
function click_fun(){ window.open("www.baidu.com");//能打开 $.ajax({ 'url': '${pageContext.request.contextPath}/activity/savePrizes.htm', 'type': 'post', 'dataType': 'json', 'data': data, success: function (data) { window.open("www.baidu.com");//被拦截 }, error:function(){ } }); }
Analysis:
Opening a new form can only be triggered within the click event , the form opened within the callback function within the click event will be intercepted, and the browser will think it is code such as advertising pop-ups
##Solution 1:
function click_fun_new(){ var tempwindow=window.open();//先打开临时窗体,由于是点击事件内触发,不会被拦截 $.ajax({ 'url': '${pageContext.request.contextPath}/activity/savePrizes.htm', 'type': 'post', 'dataType': 'json', 'data': data, success: function (data) { tempwindow.location = "www.baidu.com";//当回调的时候更改临时窗体的路径 }, error:function(){ tempwindow.close();//回调发现无需打开窗体时可以关闭之前的临时窗体 } }); }
Solution 2:
function click_fun_new(){ var flag = false; $.ajax({ 'url': '${pageContext.request.contextPath}/activity/savePrizes.htm', 'type': 'post', 'dataType': 'json', 'data': data, 'async':false,//同步请求 success: function (data) { $("#a").attr("href","www.baidu.com");//当回调的时候更改页面上或创建的某个a标签的href flag = true;//更改标志 }, error:function(){ } }); if(flag){ $("#a").click();//href属性更改后模拟点击 } }The above are two methods for opening a new form with ajax callback to prevent browser interception. I hope it will be helpful to everyone's study. I believe you have mastered the method after reading the case in this article.

要在UbuntuLinux中删除FirefoxSnap,可以按照以下步骤进行操作:打开终端并以管理员身份登录到Ubuntu系统。运行以下命令以卸载FirefoxSnap:sudosnapremovefirefox系统将提示你输入管理员密码。输入密码并按下Enter键以确认。等待命令执行完成。一旦完成,FirefoxSnap将被完全删除。请注意,这将删除通过Snap包管理器安装的Firefox版本。如果你通过其他方式(如APT包管理器)安装了另一个版本的Firefox,则不会受到影响。通过以上步骤
