Thymeleaf将JSON字符串作为JSON对象打印到javascript变量中 [英] Thymeleaf print JSON string as JSON object into a javascript variable

问题描述

具体

我需要一种方法来打印 JSON 表示a字符串值通过百科全书进入html页面。

I need a way to print JSON representation of a string value into the html page via thymeleaf.

详细

我' m具有模型属性，其中包含一个字符串，该字符串实际上是 JSON的字符串表示

I'm having a model attribute which contains a string which is actually a string representation of the JSON

我的 thymeleaf 代码

<script th:inline="javascript">
  var value = [[${data.scriptValue}]];
</script>

打印变量如下

var value = '[[\"asd\",\"3\"],[\"asd\",\"1\"],[\"asdasd\",\"1\"]]';

但我希望这样的东西是 javascript / JSON 数组

But I want something like this as a javascript/JSON array

var value = [["asd","3"],["asd","1"],["asdasd","1"]];

如何在百里香中做到这一点？

注意：我知道我可以从 JSON.Parse 执行此操作，但我需要一种方法从thymeleaf执行此操作：）

Note: I know I can do this from JSON.Parse but i need a way to do this from thymeleaf :)

此功能在Thymeleaf 3中可用

This feature is available in Thymeleaf 3

参考 Thymeleaf文本语法在 https://github.com/thymeleaf/thymeleaf/issues/395

// Unescaped (actual answer)
var value = [(${data.scriptValue})];
//or
var value = [# th:utext="${data.scriptValue}"/];

// Escaped
var value = [[${data.scriptValue}]];
//or
var value = [# th:text="${data.scriptValue}"/];

在Thymeleaf 2不可能正如Patric LC所述，报告了两个问题。

It's not possible at Thymeleaf 2. As Patric LC mentioned, there are two issues reported for this.

1. 未转义内联脚本/ css＃12

使用Jackson进行JSON＃81的Javascript内联
