我尝试对 onChange 事件使用 2 个不同的函数，如下所示：
<html:select property="distributionCategoryCode" tabindex="5" onchange="<c:choose><c:when test="${model.editT == true}">enableTextboxDirect('${model.dtxtrmks}');</c:when><c:otherwise>enableTextboxDirect();</c:otherwise></c:choose>" >
但是得到如下JSP错误：
期望引用值，得到字符：= 属性：${model.editTaxes 不是有效的属性名称期望引用值，得到字符：t
有什么输入吗？
You can't arbitrarily nest JSP tags like that, it's not legal JSP (or XML).
You need to set the value separately.
In this case I barely see a reason to special-case it in the rendered output, instead pass two parameters to enableTextboxDirect. I don't see a usecase for doing it any other way.
<html:select property="distributionCategoryCode"
onchange="enableTextboxDirect(${model.editT}, '${model.dtxtrmks}')>
Even if you had to write a one-liner JS wrapper in case you cannot modify enableTextboxDirect it's still a better solution than bothering to change the entire attribute.
