How do you assign a JavaScript 'onclick' attribute dynamically?
As the other said you should assign a function.
Just wanted to point out that in this case you want to pass a value so you need to assign an anonymous function (or a named function defined inline) like
button.onclick = function() {otherfunction(parameter)};
If the function you want to assign does NOT require a parameter you can use it directly
button.onclick = otherfunction;
Note that there is no parenthesis in this case
button.onclick = otherfunction(); // this doesn't work
won't work as it will call otherfunction
as soon as it is parsed
You have to assign a function, not a string.
backButton.onclick = function wastefulDuplicationOfBackButton () {
navigate(-1);
}
you are assigning text to the onclick, try assigning a function.
backButton.onclick = function(){navigate(-1);};
