Question

我有一个父网页表单，在点击按钮时打开了一个子窗口

我需要做的是在子窗口仍然打开时直接关闭父窗体，子窗口也应该关闭。

我为它编写了以下javascript

var opengridacc;

function OpenGridAccounts(companyId, checkRequestType, documentId) {

    var hdnDocumentId = $(document).find('#hdnDocumentId').val();

    documentId = hdnDocumentId;  


    opengridacc = window.open("../CheckRequest/GridAccounts.aspx?comp_id=" + companyId
                                 + "&CheckRequestType=" + checkRequestType
                                 + "&DocumentId=" + documentId,
                             "GridAccounts",  "height=755px,width=1280px,center=yes,status=no,scrollbars=yes,toolbar=no,menubar=no,left=0,top=0");

    return false;

}



function closegrdacc() { 

    if(!opengridacc) {

        opengridacc.close();

    }

}

但即出现错误，即关闭未定义

Answer 1

更改closegrdacc，如下所示

function closegrdacc() { if(opengridacc!=null) { opengridacc.close(); } }

Answer 2

你能试试吗，

if(opengridacc!=undefined) { opengridacc.close(); }

Answer 3

您应该检查评估是否为true。

function closegrdacc() {
    // this would return false if either opengridacc is null or undefined
    if(opengridacc) {
        opengridacc.close();
        opengridacc = null; // clean up for a new call
    }
}

此外，您可能还想在打开时检查它是否已存在

var opengridacc;

function OpenGridAccounts(companyId, checkRequestType, documentId) {
    if (opengridacc) // it has already been assigned a window
        return false;
    var hdnDocumentId = $(document).find('#hdnDocumentId').val();
    documentId = hdnDocumentId;  
    opengridacc = window.open("../CheckRequest/GridAccounts.aspx?comp_id=" + companyId +
                              "&CheckRequestType=" + checkRequestType +
                              "&DocumentId=" + documentId,
                              "GridAccounts",
                              "height=755px,width=1280px,center=yes,status=no,scrollbars=yes,toolbar=no,menubar=no,left=0,top=0"
                             );

    return false;

}

javascript关闭不工作
