symfony - SyntaxError：标识符在树枝文件中显示数字文字后立即开始

Question

{% block reviewresult %}
<div class="scrollerList"> 
</div>

{% endblock %}
{% block myJavascript %}
<script>
    var stateObject = {};
    var title = "Single";
    var urlEncode = "'" +{{ tag|url_encode(true) }} + "'";
    alert(urlEncode);

    var newUrl = baseUrl + "/taglist/" + urlEncode.toString();

    $(document).ready(function() {
        ShuffleObj.changeUrl(stateObject, title, newUrl);

        ffleObj.setScrollUrl(baseUrl + '/taglist/playlist/' + urlEncode.toString());
    });
</script>
{% endblock %}

上面的代码var urlEncode = "'" +{{ tag|url_encode(true) }} + "'";显示错误 SyntaxError: identifier 在 numeric literal 之后立即开始。在这个问题中，标签值为tag= 123 Forever;

Answer 1

这个：

var urlEncode = "'" +{{ tag|url_encode(true) }} + "'";

将产生以下代码：

var urlEncode = "'" + someTag + "'";

并且 js 将 someTag 解释为标识符。所以，试试这个：

var urlEncode = ' {{ tag|url_encode(true) }} ';
