如何使用 javascript 变量访问模型属性 [英] How do you access a model attribute with javascript variable

问题描述

我在春天向我的 ModelAndView 添加一个属性，然后我将它转发到我的 thymeleaf 视图.

I'm adding an attribute to my ModelAndView in spring and after this i forwarding it to my thymeleaf view.

在视图中我有以下代码:

In the view i have the following code:

<script th:inline="javascript">
        /*<![CDATA[*/
            var applicationName = /*[[${T(com.sample.constants.ApplicationConstants).MODEL_ATTR_COLLECTED_VALUES}]]*/ "Test";
            var collectedValueJson = [[${collectedValues}]];
            console.log(collectedUserJson);
        /*]]>*/
</script>

结果是

var applicationName = 'collectedValues';
var collectedUserJson = '[{\"givenname\":\"Muster\",\"surname\":\"Peter\"}]';

没关系.现在我的愿望是，我可以使用 var application 并使用此变量访问 modelattribute，但这不起作用.

That's fine. Now my wish for this is, that i can take the var application and access with this variable the modelattribute, but that's not working.

结果如下:

var tmp2 = ${applicationName};

另一个尝试是，我可以从第一次尝试使用语法 /*[[ ]]*/ 访问模型属性:

An other try was, that i have access to the modelattribute with the syntax /*[[ ]]*/ from the first try:

var applicationName = ${/*[[${T(com.sample.constants.ApplicationConstants).MODEL_ATTR_COLLECTED_VALUES}]]*/};

但结果将是:

var tmp = ${'collectedValues'

我不知道我可以尝试什么.

i have no idea what can i try.

还有其他建议吗?

提前致谢.

推荐答案

您无法访问模型属性，因此它们位于服务器端，并且在将 jsp 渲染为 HTML 时丢失了它们

there is no way you can access model atributes hence they are on server side and they where lost when rendering jsp into HTML
