单击按钮时如何调用 javascript 函数? [英] How do I call a javascript function when a button is clicked?

问题描述

现在我正在使用:

<%=button_to_function "✓", checkButton(), :class => "buttonGrey"%>

但是 javascript 函数需要向它传递一些东西，以便它可以切换类(我希望在按下按钮时更改按钮类)我将传递什么作为参数来表示按钮?

But the javascript function needs something to be passed to it so it can toggle the class( I want the buttons class to be changed upon pressing it) What would I pass as a param to represent the button?

推荐答案

可以直接在button_to_function中执行javascript.

You can execute javascript directly in the button_to_function.

就你而言:

<%= button_to_function "✓", '$(this).toggleClass("buttonGrey buttonGreen");', :class =>"buttonGrey" %>

希望这会有所帮助！
