I use a loop through the node elements to get the ID from the clicked element. Until then all good and it works. Now I want to call an another function in my class & get this error:
this._PreLoad is not defined at HTMLElement.s.onclick
this._joinnews.forEach((node) => {
node.onclick = function(){
const requestData = `newsid=${node.id}`;
// some code //
this._PreLoad(true); // ERROR
// _PreLoad(true); not working
// this._PreLoad(true).bind(this); not working (I am not yet familiar with the bind function)
}
});
Are the functions inside a node loop unknown ?
The correct place to bind this is here:
node.onclick = function() {
const requestData = `newsid=${node.id}`;
// some code //
this._PreLoad(true);
}.bind(this); // bind here!
Alternatively, use an arrow function which preserves this as whatever it was at the time of the function declaration:
node.onclick = () => {
const requestData = `newsid=${node.id}`;
// some code //
this._PreLoad(true);
}
