Thymeleaf:如何在使用Thymeleaf的JavaScript中使用布尔运算符

Question

我在javascript使用中使用thymeleaf,th:inline="javascript"但是当我们在java脚本中添加布尔条件时,thymeleaf会出现如下异常:

org.xml.sax.SAXParseException; lineNumber: 14; columnNumber: 22; The entity name must immediately follow the '&' in the entity reference.
com.sun.org.apache.xerces.internal.util.ErrorHandlerWrapper.createSAXParseException(ErrorHandlerWrapper.java:203)
com.sun.org.apache.xerces.internal.util.ErrorHandlerWrapper.fatalError(ErrorHandlerWrapper.java:177)
com.sun.org.apache.xerces.internal.impl.XMLErrorReporter.reportError(XMLErrorReporter.java:441)

com.sun.org.apache.xerces.internal.impl.XMLDocumentFragmentScannerImpl.scanEntityReference(XMLDocumentFragmentScannerImpl.java:1845)

以下是我的javascript代码:

<script type="text/javascript" th:inline="javascript">
    $(document).ready(function(){
        $('.fancybox').fancybox({
            'width' :'623px',
            'maxHeight':'156px'
        });

        var catId = $("#category").val();
        if(catId != null && catId != ''){
            findSubCategories();
            /*<![CDATA[*/
                var subCatId = /*[[${searchProductDto.subCategory}]]*/
            /*]]>*/
            debugger;
            if(subCatId != null){
                $("#subCategory").val(subCatId);
            }
        }
    });

用<![CDATA[块包装if 块

<script type="text/javascript" th:inline="javascript">
var a =b = true;
/*<![CDATA[*/
if(a && b){
    alert('Yea');
}/*]]>*/
</script>
