如何在inner.html中调用函数

Question

This is my normal function in JS file. I need to closeHomeScreenPopup function which is defined inside the document.getElementById("addToHomeScreenPrompt").innerHTML . I have passed onclick as string as you can see.

export default function register() {
  // Checks if should display install popup notification:
  if (isIos() && !isInStandaloneMode()) {
    function closeHomeScreenPopup() {
      console.log("jkjilkjlkjlkjlkjlkjlk");
    }
    document.getElementById("addToHomeScreenPrompt").innerHTML =
      '<div onclick="closeHomeScreenPopup()"><span class="plush--sign">+</span><p>Install the webapp on your iPhone:tap <img style="width: 20px; margin: 0 4px;" alt="" src="img/share_icon.png"/> and then Add to homescreen.</p></div>';
  }
}

But I get error when do onclick on the div

Uncaught ReferenceError: closeHomeScreenPopup is not defined
    at HTMLDivElement.onclick (temperature-schedule?roomId=2:51)

How can I call the closeHomeScreenPopup from inside inner.html

Answer 1

Everything in JS is bound to containing scope. Therefore, if you define a function directly in the register functions, it will not be bound to window object.

closeHomeScreenPopup function should be defined globally

 window[closeHomeScreenPopup] = function() {
      console.log("jkjilkjlkjlkjlkjlkjlk");
    }

 function closeHomeScreenPopup() { console.log("jkjilkjlkjlkjlkjlkjlk"); } document.getElementById("addToHomeScreenPrompt").innerHTML = '<div onclick="closeHomeScreenPopup()"><span class="plush--sign">+</span><p>Install the webapp on your iPhone:tap <img style="width: 20px; margin: 0 4px;" alt="" src="img/share_icon.png"/> and then Add to homescreen.</p></div>'; 

 <div id="addToHomeScreenPrompt"></div>
