I'm trying to create a webpage using php, on an element of class "Continuous TextBox" (defined by my class), when clicked it has to start a Javascript function which should change the content id of another function" harta-modal" element, but this doesn't happen. I keep getting the same error, "Uncaught TypeError: Cannot set property of undefined (set 'innerHTML')" even though the function is declared after the element it is supposed to change, and the control I wrote within it Taiwan Log This function does not return null. What did i do wrong?

location.href='loginPage.html'"; } ?>    Crisis Containment Service

When usinggetElementByIdto get an element, you do not have to use[0]to access the first element since it can only return one element.

Frommozilla documentation:

So just use:

function makeMap(longitude, latitude){ console.log(document.getElementById('harta-modal')); document.getElementById('harta-modal').innerHTML = `${longitude} ${latitude}`; }
