Here is the code snippet I am currently working with:
document.getElementById(myid).onclick = function() {
HandleGPIO(val1, val2);
};
if (console) {
console.log(document.getElementById(myid).getAttribute('onclick'));
}
My goal is to determine how the function HandleGPIO() was assigned.
Does anyone know an effective way to debug this? The getAttribute method doesn't seem to be working in this case and only returns null.
Retrieve the content of onclick using this code snippet:
console.log(document.getElementById(myid).onclick.toString());
To inspect the function's input values, we can make it return them. By utilizing an argument, we segregate debugging logic from regular execution logic:
for (var i = 0; i < arr_inputs.length; i++) {
(function(i) {
document.getElementById(arr_inputs[i]).onclick = function(debug) {
if(debug === true) {
return [arr_inputs[i], 0];
}
else {
HandleGPIO(arr_inputs[i],0);
}
};
})(i);
}
Simply invoke the function with the argument set to true like so:
console.log(document.getElementById(myid).onclick(true));
This will output an array containing the values passed to this function instance.
