window.open打开页面会被浏览器拦截问题解决

// 先打开新页签
var  tempWin  = window.open("_blank"); // window.open("about:blank"); 
$.ajax({
            type: "post",
            url: xxx,
            data: data,
            contentType: "application/json;charset=UTF-8",
            success: function (response) {
                   //给新页签设置跳转链接
                  tempWin.kk = "www.baidu.com";  
            }
        });

function getParam(a) {
            var b = new RegExp("(^|&)" + a + "=([^&]*)(&|$)");
            var r = window.location.search.substr(1).match(b);
            if (r != null) return unescape(r[2]);
            return ""
        }

$.ajax({
        type: "post",
        url: "/xxxx/xxxx",
        async: false，// 设置同步（默认异步）
        data: data,
        contentType: "application/json;charset=UTF-8",
        success: function (data) {
            if(xxx){
                window.open(url);
            }
        }
    });

 <a href="" target="_blank">click me</a>

 # 点击这个超链接，浏览器会认为它是打开一个新的链接，就不会拦截。
 <a href="javascript:void(0)" onclick="window.open()"></a>

 setTimeout('window.open(url);', 500);

var form = document.createElement('form');
form.action = 'www.baidu.com?id=1';
form.target = '_blank';
form.method = 'POST';

document.body.appendChild(form);
form.submit();

function newWin(url, id) {
      var a = document.createElement('a');
      a.setAttribute('href', url);
      a.setAttribute('target', '_blank');
      a.setAttribute('id', id);
      // 防止反复添加
      if(!document.getElementById(id)) {         
        document.body.appendChild(a);
      }
      a.click();
