How to open a new window in jquery

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

var tempwindow=window.open('_blank');
tempwindow.location='www.baidu.com' ;

/* 在新窗口中打开 */
function openNewWindow(url) {
    var a = document.createElement('a');
    a.setAttribute('href', url);
    a.setAttribute('target', '_blank');
    var id = Math.random(10000, 99999);
    a.setAttribute('id', id);
    // 防止反复添加
    if (!document.getElementById(id)) {
        document.body.appendChild(a);
    }
    a.click();
}
//方法调用
openNewWindow('www.baidu.com');
