"colon expected" javascript 在 IE 中调用 ajax 时出错

Question

我正在使用 Knockout JS 并使用以下方法进行 ajax 调用。最近我注意到一个控制台错误 Expected ':'，发生在 Internet Explorer 11 上。这在 Chrome 中工作正常。有没有 IE 无法正确处理的问题？

app.getAutoGeneratedSubmissionAttachments = function (carrierId, employerId, formId, submissionTypeId, IsMedical, IsDental, IsLife, IsVision, callBack) {
    $.ajax({
        url: $('#GetAutoGeneratedSubmissionAttachments').data('url'),
        type: 'GET',
        dataType: 'json',
        data: { IsMedical, IsDental, IsVision, IsLife, carrierId: carrierId, employerId: employerId, formId: formId, submissionTypeId: submissionTypeId },
        success: function (data) {
            callBack(data);
        },
        fail: function (data) {
            $.unblockUI();
            toastr.error("An error has occured on the server when retrieving additional submission documents.");
        }
    })
}

Shorthand 对象属性（例如：let o = {a, b, c}）是 ES6 特性，IE11 不支持

要修复它，请更改您的数据以使用标准 key: value 表示法。

    data: { IsMedical: IsMedical, IsDental: IsDental, IsVision: IsVision, IsLife: IsLife, carrierId: carrierId, employerId: employerId, formId: formId, submissionTypeId: submissionTypeId },
