调用与按钮属性匹配的函数

Using TypeScript how can I trigger a function matching the onclick attribute.

使用TypeScript如何触发匹配onclick属性的函数。

<button onclick="window.open('myapp://', '_system')">Goto App</button>

So that means whenever someone clicks on button above, I will call a JavaScript function to take the user to www.google.com

这意味着只要有人点击上面的按钮,我就会调用JavaScript函数将用户带到www.google.com

Please note that I don't have control over this button or else It would have attached a method on the onclick.

请注意,我无法控制此按钮,否则它会在onclick上附加一个方法。

• You can get access to the button using document.querySelectorAll. https://developer.mozilla.org/en-US/docs/Web/API/Document/querySelectorAll

  您可以使用document.querySelectorAll访问该按钮。 https://developer.mozilla.org/en-US/docs/Web/API/Document/querySelectorAll

• Once you have access (e.g. in a variable btn) use btn.addEventListener('click',()=>stuff) https://developer.mozilla.org/en-US/docs/Web/API/EventTarget/addEventListener

  一旦你有权访问(例如在变量btn中),使用btn.addEventListener('click',()=> stuff)https://developer.mozilla.org/en-US/docs/Web/API/EventTarget/addEventListener
