DOMContentLoaded. Here's the code that does this:
```js
document.addEventListener('DOMContentLoaded',function() {
});
```
You can implement event handlers that go inside of the DOMContentLoaded function. You can implement an onclick event handler which triggers when the user clicks on the element with id getMessage, by adding the following code:
```js
document.getElementById('getMessage').onclick=function(){};
```
DOMContentLoaded function for the element with id of getMessage.
document.getElementById method to select the getMessage element.
testString: assert(code.match(/document\s*\.getElementById\(\s*?('|")getMessage\1\s*?\)/g), 'Your code should use the document.getElementById method to select the getMessage element.');
- text: Your code should add an onclick event handler.
testString: assert(typeof document.getElementById('getMessage').onclick === 'function', 'Your code should add an onclick event handler.');
```
```
