javascript - 弹出html页面没有返回值？

Question

请问有人可以帮我吗？以下 JavaScript 代码适用于 IE9 及以上版本和 Firefox，但较低版本的 IE(8,7) 不支持。

function SetName() {
    var a = sessionStorage.getItem("sent");
    var b = window.opener.document.getElementById("tclass").value;
    var c = window.opener.document.getElementById("ttype").value;
    var noPMMCode = window.opener.document.getElementById("noPMMCode").value;
    var noLTMMCode = window.opener.document.getElementById("noLTMMCode").value;
    var noLEMMCode = window.opener.document.getElementById("noLEMMCode").value;
    var noSTMMCode = window.opener.document.getElementById("noSTMMCode").value;
    if (window.opener != null && !window.opener.closed && b == "Material" && c == "PT" && noPMMCode != null) {
        var txtName = window.opener.document.getElementById("PMMC" + a);
        txtName.value = document.getElementById("ddlNames").value;
    } else if (window.opener != null && !window.opener.closed && b == "Material" && c == "LT-NORMAL" && noLTMMCode != null) {
        var txtName = window.opener.document.getElementById("LTMMC" + a);
        txtName.value = document.getElementById("ddlNames").value;
    } else if (window.opener != null && !window.opener.closed && b == "Material" && c == "LT-EMPANEL" && noLEMMCode != null) {
        var txtName = window.opener.document.getElementById("LEMMC" + a);
        txtName.value = document.getElementById("ddlNames").value;
    } else if (window.opener != null && !window.opener.closed && b == "Material" && c == "ST" && noSTMMCode != null) {
        var txtName = window.opener.document.getElementById("STMMC" + a);
        txtName.value = document.getElementById("ddlNames").value;
    }
    window.close();
}

提前谢谢..

window.opener 在默认安全级别下的 IE 中不起作用。

一种选择是使用location.href将子窗口重定向到与父窗口相同域中的页面，然后使用window.opener
