代码可以在Chrome和Edge中使用，但不能在IE中使用-setimeout？

标签： javascript jquery html

我有以下downloadZip.html。下载适用于Chrome和Edge，但不适用于IE。该文件从jspf页面被调用如下。当我单击“下载列出的文档”时，它将调用popupDownloadWindow（），它将在plainview中打开downloadZip.html。加载时此html调用enableLink（），流程进行。由于视图是纯视图，因此只有在执行enableLink（）块的情况下才首先执行（if（callerview ==“ plainview”））。不知道是否由于setTimeout（）而发生这种情况。请在这里帮助我。让我知道任何信息。

function checkReturn(){
    //alert('checkReturn - sessionsNotOk global var = '+sessionsNotOk);
    if (sessionsNotOk != "DEF") {

        var docbases = sessionsNotOk.split(",");
        //alert('checkReturn - docbases arr = '+docbases+', length='+docbases.length);
        if (docbases.length == 1 && docbases[0] == "OK"){
            // All sessions are faja
            document.getElementById('divIndicator').style.display='none';
            document.getElementById('checkSession').style.display='none';
            document.getElementById('noSession').style.display='none';
            document.getElementById('dlink').style.display='inline';
            document.getElementById('dlink').style.textAlign='center';
            document.getElementById('dlink').style.display='';

        } else {
                // We need to show the sublogin dialog
                var nextDocbase = docbases[0];

                //alert("Next NOT AVAILABLE session = "+nextDocbase);
                window.opener.$('#subloginmessage').css('display','none');
                window.opener.$('#loginIndicator').css('display','none');
                window.opener.$('#sub-uid').val(window.opener.$('#user_name').text());
                window.opener.$('#sub-uid').attr('disabled','disabled');
                window.opener.$('#sub_docbase').text(nextDocbase);

                document.getElementById('noSession').style.textAlign='center';

        return;
    }
    //Check again in 0.5 second
    setTimeout("checkReturn()",500);
    //setTimeout(function() {
