$(function () {
    var ue = UE.getEditor('content',{
        serverUrl:'{:\\think\\Url::build("Ueditor/index")}',
        initialContent: '{$vo.content ?? ""}'
    });

    var converter = new showdown.Converter(),
        text      = $("#markdown_tpl").html();
    $("#markdown").html(converter.makeHtml(text));
})


'{$vo.content ?? ""}'正确

"”{$vo.content ?? ''}"错误
