javascript - Was soll ich tun, wenn Chrome keine showModalDialog-Methode hat?

Question

Beim Besuch einiger Router-Einstellungsseiten kann Chrome das Einstellungsfenster nicht normal öffnen, da es relativ alt ist.
In der Konsole wird ein Fehler gemeldet: showModalDialog-Methode existiert nicht.

Answer 1

直接把对应的showModalDialog方法改成open就可以了

另stackoverflow上的代码，但是有时候不起作用

<script type="text/javascript">
  // fix for deprecated method in Chrome 37
  if (!window.showModalDialog) {
     window.showModalDialog = function (arg1, arg2, arg3) {

        var w;
        var h;
        var resizable = "no";
        var scroll = "no";
        var status = "no";

        // get the modal specs
        var mdattrs = arg3.split(";");
        for (i = 0; i < mdattrs.length; i++) {
           var mdattr = mdattrs[i].split(":");

           var n = mdattr[0];
           var v = mdattr[1];
           if (n) { n = n.trim().toLowerCase(); }
           if (v) { v = v.trim().toLowerCase(); }

           if (n == "dialogheight") {
              h = v.replace("px", "");
           } else if (n == "dialogwidth") {
              w = v.replace("px", "");
           } else if (n == "resizable") {
              resizable = v;
           } else if (n == "scroll") {
              scroll = v;
           } else if (n == "status") {
              status = v;
           }
        }

        var left = window.screenX + (window.outerWidth / 2) - (w / 2);
        var top = window.screenY + (window.outerHeight / 2) - (h / 2);
        var targetWin = window.open(arg1, arg1, 'toolbar=no, location=no, directories=no, status=' + status + ', menubar=no, scrollbars=' + scroll + ', resizable=' + resizable + ', copyhistory=no, width=' + w + ', height=' + h + ', top=' + top + ', left=' + left);
        targetWin.focus();
     };
  }
</script>
