插入的签名行中的Arial字体将更改为插入时的新浪漫时间

Question

我在编写邮件时使用Office.js插入签名。我的问题是，在第一次插入时，它将字体和字体大小更改为错误的值，如果我再次插入或插入一些其他签名，而不是正确插入它。 在此特定示例中，Outlook中的所有设置都设置为Arial 11，我要插入的签名也是Arial 11.

function mergeAndInsertHtmlTemplate(_html, _json, isSignature, templateId, onDoneCallback, directMerge) {
        getMailBody(function (_htmlBody) {
            if (!_htmlBody.startsWith("<template>")) {
                var t = document.createElement("template");
                t.innerHTML = _htmlBody;
                _htmlBody = t.outerHTML;
            }

            // template html merged with data
            var _mergedHtml = mergeHtmlAndJson(_html, _json);
            if (isSignature) {
                var mergedSignature = mergeHtmlSignature(_htmlBody, _mergedHtml);
                if (mergedSignature.succeeded) {
                    updateMailBody(mergedSignature.html, function (result) {
                        factory.PrependData("");
                    });
                }
                else {
                    insertAtCursorLocation(_mergedHtml); // insert at cursor location
                }
            }
            else {
                if (Object.keys(_json).length > 0 && !directMerge) {
                    _mergedHtml = mergeMustachAndJson(_htmlBody, _json, true);
                    updateMailBody(_mergedHtml);
                }
                else {
                    _mergedHtml = mergeMustachAndJson(_html, _json);
                    insertAtCursorLocation(_mergedHtml);
                }
            }
            if (onDoneCallback) onDoneCallback();
        });
    }

function mergeHtmlSignature(mailBodyHtml, signatureHtml) {

        if (!mailBodyHtml.startsWith("<template>")) {
            var t = document.createElement("template");
            t.innerHTML = mailBodyHtml;
            mailBodyHtml = t.outerHTML;
        }

        var $mailBody = $(mailBodyHtml);
        var endComposeIndex = $mailBody.find("*").index($mailBody.find('a[name=_MailEndCompose]'));
        // $mailBody.find('[style*="_MailAutoSig"]').parent().not('div').empty(); // tryout: signature inserted twice 
        var toRemove = [];
        $mailBody.find('*[class*=iw-signature]:not(:has(a[name=_MailAutoSig]))').each(function () {
            var thisIndex = $mailBody.find("*").index($(this));
            if(endComposeIndex < 0 || thisIndex < endComposeIndex){//if ($(this).prevAll().filter("a[name=_MailEndCompose]").length == 0) {
                var parentTables = $(this).parents("table");
                toRemove.push(parentTables);
                toRemove.unshift($(this));
            }
        });

        for (var i = 0; i < toRemove.length; i++) {
            toRemove[i].remove();
        }

        $mailBody.find('[style*="_MailAutoSig"]').each(function () {
            var parentTables = $(this).parents("table");
            toRemove.push(parentTables);
            $(this).remove();
        });

        for (var i = 0; i < toRemove.length; i++) {
            toRemove[i].remove();
        }

        var _signatureLocations = $mailBody.find('a[name=_MailAutoSig]');

        if (_signatureLocations && _signatureLocations.length > 0) {
            _signatureLocations.parent().empty().html(signatureHtml);
            return { html: $mailBody[0].outerHTML, succeeded: true }
        }
        else {
            $log.warn('No signature location to insert signature. Inserting at cursor location');
            return { html: signatureHtml, succeeded: false };
        }
    }

function insertAtCursorLocation(data) {
        if (factory.BodyType === MailBody.HTML) {
            // Body is of HTML type. Specify HTML in the coercionType parameter of setSelectedDataAsync.
            Office.context.mailbox.item.body.setSelectedDataAsync(data,
                {
                    coercionType: Office.CoercionType.Html,
                    asyncContext: { var3: 1, var4: 2 }
                },
                function (asyncResult) {
                    if (asyncResult.status === Office.AsyncResultStatus.Failed) {
                        $log.error(asyncResult.error.message);
                    }
                });
        }
        else {
            Office.context.mailbox.item.body.setSelectedDataAsync(data,
                {
                    coercionType: Office.CoercionType.Text,
                    asyncContext: { var3: 1, var4: 2 }
                },
                function (asyncResult) {
                    if (asyncResult.status === Office.AsyncResultStatus.Failed) {
                        $log.error(asyncResult.error.message);
                    }
                });
        }
    }

function updateMailBody(data, callback) {
        Office.context.mailbox.item.body.setAsync(data, { coercionType: factory.BodyType }, function (result) {
            if (callback) callback(result);
        });
    }

这是我要插入的签名：

<div>
<a name="_MailAutoSig">
    <div class="iw-signature" style="-aw-headerfooter-type: header-primary;">
        <p class="iw-signature" style="margin: 0pt;">
            <span class="iw-signature" style="font-family: Calibri; font-size: 11pt;">&nbsp;</span>
        </p>
    </div><p class="iw-signature" style="margin: 0pt 0pt 8pt; line-height: 108%; font-size: 11pt;">
        <span class="iw-signature" style="font-family: Arial; font-size: 11pt;">Kind regards,</span>
    </p><p class="iw-signature" style="margin: 0pt 0pt 8pt; line-height: 108%; font-size: 11pt;">
        <span class="iw-signature" style="font-family: Arial; font-size: 11pt;">This one is also with ARIAL 11.</span>
    </p><p class="iw-signature" style="margin: 0pt 0pt 8pt; line-height: 108%; font-size: 11pt;">
        <span class="iw-signature" style="font-family: Arial; font-size: 11pt;">Byeeeeeeeeeeee</span>
    </p>
    <div class="iw-signature" style="-aw-headerfooter-type: footer-primary;">
        <p class="iw-signature" style="margin: 0pt;">
            <span class="iw-signature" style="font-family: Calibri; font-size: 11pt;">&nbsp;</span>
        </p>
    </div>
</a>

我正在这样做，而邮件正文是空的，所以邮件正文有默认值，函数insertAtCursorLocation（data）被调用，其中数据是签名html本身。

您可以在下一张图片上看到字体样式和大小：

signature line when first inserted

Signature line when inserted for second time

你能否告诉我解决这个问题的最佳方法是什么？即使它是解决方法，对我来说也意味着很多。
