问题描述
我有以下代码:
function someMethod()
{
$(obj).click(function {});
}
someMethod被调用两次,因此click事件被绑定两次.如何使它只绑定一次?
someMethod is called twice and thus click event is binded twice. How can I make it bind only once?
推荐答案
如果可以应用它,可能想看看 event.preventDefault 和 event.stopPropagation 或每次都在您的方法之内取消绑定并绑定,例如
If you can apply it, probably want to take a look at event.preventDefault and event.stopPropagation OR unbind and bind each time, within your method like
function someMethod()
{
$(obj).off('click').on('click', function(e) {
// put your logic in here
});
}
