window.open打开一个新空白页面，不会自动刷新解决方案

调用js方法：

function BuildPostForm(fm, url, target) {
    var e = null, el = [];
    if (!fm || !url)
        return e;
    target = target || ‘_blank‘;
    e = document.getElementById(fm);
    if (!e) {
        e = document.createElement(‘Form‘);
        e.Id = fm;
        document.body.appendChild(e);
    }

    e.method = ‘post‘;
    e.target = target;
    e.style.display = ‘none‘;
    e.enctype = ‘application/x-www-form-urlencoded‘;

    var idx = url.indexOf(‘?‘);
    var para = [], op = [];
    if (idx > 0) {
        para = url.substring(idx + 1, url.length).split(‘&‘);
        url = url.substr(0, idx);//截取URL
        var keypair = [];
        for (var p = 0; p < para.length; p++) {
            idx = para[p].indexOf(‘=‘);
            if (idx > 0) {
                el.push(‘<input type="hidden" name="‘ + para[p].substr(0, idx) + ‘" id="frm‘ + para[p].substr(0, idx) + ‘" value="‘ + para[p].substring(idx + 1, para[p].length) + ‘" />‘);
            }
        }
    }

    e.innerhtml = el.join(‘‘);
    e.action = url;
    return e;
}

 

用这个方法提交就搞定了。

调用方法：

BuildPostForm(‘pay_form‘, url, ‘_blank‘).submit();
