why my code is not working when i try to get button value by getElementsByClassName method instead of querySelector method
var bindTaskEvents = function(taskListItem, checkBoxEventHandler) {
console.log("Bind list item events");
//select taskListItem's children
var checkBox = taskListItem.querySelector("input[type=checkbox]");
var editButton = taskListItem.querySelector("button.edit");
var deleteButton = taskListItem.querySelector("button.delete");
//bind editTask to edit button
editButton.onclick = editTask;
//bind deleteTask to delete button
deleteButton.onclick = deleteTask;
//bind checkBoxEventHandler to checkbox
checkBox.onchange = checkBoxEventHandler;
}

Courses Plus Student 16,968 PointsHi Arsalan,
Just to let you know, I edited your post just to format the code properly, if you need help doing this in future posts there is a handy Markdown Cheatsheet that will explain how to paste code into your forum posts.
As for your question, can you be more specific where you are encountering an issue?
