VisualizaçõesIs it possible to run an onclick javascript function inside another javascript function?
Currently learning javascript and was curious about this possibility. I have this code inside a .JS file
var x = document.createElement("IMG");
x.setAttribute("src", "helpimage.png");
x.setAttribute("width", "20");
x.setAttribute("height", "20");
x.setAttribute("alt", "help image");
x.setAttribute("id","image");
var row = document.createElement('div');
row.classList.add('row');
var label = document.createElement('div');
label.id = machineName + '-label';
label.classList.add('col-md-5');
label.innerHTML = humanName + ':';
label.appendChild(x);
label.onclick = function() {myFunction()};
row.appendChild(label);
and this function titled "MyFunction"
function myFunction() {
document.getElementById(machineName + '-label').innerHTML = "YOU CLICKED ME!";
}
What this code does is that first a function is called which creates a simple form element with a label. I attach a picture labeled "x" into the label. I would like to be able to click that label, with an onclick event, and then change it to whatever I want. (just testing here)
So once my first function generates my form, I then want to click my label and have it change to "YOU CLICKED ME".
Except when I click the picture nothing happens.
Can anyone tell me what I'm doing wrong?
picture of what I want to click.

Put the text that you want to replace in another nested element, rather than in the element that also contains the image.
var x = document.createElement("IMG");
x.setAttribute("src", "helpimage.png");
x.setAttribute("width", "20");
x.setAttribute("height", "20");
x.setAttribute("alt", "help image");
x.setAttribute("id", "image");
var row = document.createElement('div');
row.classList.add('row');
var label = document.createElement('div');
let machineName = "filename";
label.id = machineName + '-label';
label.classList.add('col-md-5');
let humanName = "File Name";
let text = document.createElement("span");
text.id = machineName + "-text";
text.innerHTML = humanName + ':';
label.appendChild(text);
label.appendChild(x);
label.onclick = function() {
myFunction()
};
row.appendChild(label);
document.body.appendChild(row);
function myFunction() {
document.getElementById(machineName + '-text').innerHTML = "YOU CLICKED ME!";
}
