Jquery：mousedown效果（左击时按住） [英] Jquery: mousedown effect (while left click is held down)

问题描述

我需要一个函数，当按钮被按下时执行函数，当按钮被放开时停止执行

I need a function that executes a function while a button is pressed and stops executing when the button is let go

$('#button').--while being held down--(function() {
     //execute continuously
}); 

推荐答案

我相信这样会有效：

var timeout, clicker = $('#clicker');

clicker.mousedown(function(){
    timeout = setInterval(function(){
        // Do something continuously 
    }, 500);

    return false;
});

$(document).mouseup(function(){
    clearInterval(timeout);
    return false;
});
