简单了解JS打开url的方法

window.open(loginurl_withaout, "_blank");

$.ax('./front/getURLBySidAndUid', {sysid:sysid}, 'POST', function(d) {
  var loginurl_withaout = d.loginurl + "?"+d.namefield+"="+d.username+"&"+d.pwdfield+"="+d.userpwd;
  console.info(loginurl_withaout);
  window.open(loginurl_withaout, "_blank");
}, function(e) {
  layer.alert('出问题啦~请稍后再试~',{title:'提示',icon: 2});
}, false); //同步

/获取系统带参数的登录url/
$.ax('./front/getURLBySidAndUid', {sysid:sysid}, 'POST', function(d) {

  /get跳转/
  /var loginurl_withaout = d.loginurl + "?"+d.namefield+"="+d.username+"&"+d.pwdfield+"="+d.userpwd;
  window.open(loginurl_withaout, "_blank");/

  /post跳转/
  var params = new Array();
  params.push({ name:d.namefield,value:d.username},{name:d.pwdfield,value:d.userpwd});
  openPostWindow(d.loginurl,params,"_blank");
}, function(e) {
  layer.alert('出问题啦~请稍后再试~',{title:'提示',icon: 2});
}, false); //同步

    动态创建form表单 - 实现post带参数跳转到新tab页
   /
  function openPostWindow(url,params,name){
    var tempForm = document.createElement("form");
    tempForm.id="tempForm_post";
    tempForm.method="post";
    tempForm.enctype="application/x--form-urlencoded";
    tempForm.action=url;
    tempForm.target=name; /打开新窗口/
    tempForm.style.display = "none";
    //添加参数
    for (var item in params) {
      var input = document.createElement("input");
      input.name = params[item].name;
      input.value = params[item].value;
      tempForm.appendChild(input);
    }
    document.body.appendChild(tempForm);
    tempForm.submit();
    document.body.removeChild(tempForm);
  }
