用Thymeleaf进行Javascript函数调用 [英] Javascript function call with Thymeleaf

问题描述

我需要在thymeleaf模板上调用javascript函数，如下所示:

I need to call a javascript function on thymeleaf template, something like this:

情况1:

<select th:onclick="${'function1('a')'}">

但是在这种情况下，百里香无法工作..一些研究(包括stackoverflow)之前，我得到以下解决方案":

But in this case the thymeleaf not work.. some researchs ago (including stackoverflow) I get the followings "solutions":

情况2:

<select th:onclick="${'function1(''a'')'}">

情况3:

<select th:onclick="${'function1(\'a\')'}">

情况4:

<select th:onclick="${'function1(\''+'a'+'\')'}">

但是在所有情况下，我都会遇到相同的错误:"...评估SpringEL表达式的异常..."

But in all cases I get the same error: "...Exception evaluating SpringEL expression..."

我的问题是关于javascript调用的，我需要在js函数中放置一些参数$ {var}来进行调用.我该如何解决?

My problem is about javascript callings, I need put some parameters ${var} for call in js function. How I can fix that ?

谢谢

推荐答案

如果您在JS函数调用中不需要任何动态变量，这是这样做的方法:

If you don't need any dynamic vars in the JS function call, this is how to do it:

th:onclick="'alert(\'a\');'"

这只是转义单引号，不需要SpringEL(当然，在这种情况下，您可以省去thymeleaf属性，而只需使用普通的onclick).

This simply escapes the single quotes and requires no SpringEL (of course you could dispense with the thymeleaf attribute in this case and just use plain onclick).

要在其中插入vars:

To insert vars into it:

th:onclick="'alert(\'' + ${myVar} + '\');'"

使用警报功能让我尝试一下并证明它有效.希望有帮助.

Used the alert function to allow me to try it out and prove it works. Hope that helps.
