window.open()弹窗被浏览器拦截

什么情况下会弹窗被拦截 obj.onclick = function(){ window.open(url) // 会被拦截 } obj.onclick = function () { ajax({ url: ‘/xxxxxx/’, success: function (url) { window.open(url); //会被拦截 } }) }});　　解决 obj.onclick = function () { var newWindow = window.open(); //先在回调函数之前打开新窗口，后再加载url ajax({ url: ‘/xxxxxx/’, success: function (url) { newWindow.location.href = url; } }) }
