elem.dispatchEvent(),接收一个参数,创建的event的对象实例。 兼容性方法的写法: functionfireEvent(elem , type , args ){//第一个参数代表要触发的事件绑定的元素,第二个参数代表要触发的事件类型,第三个是需要传入event对象实例的属性值args= args || {};//比如传入{name:"chaojidan",eventName:"zidingyi"...
functionaddEvent(obj,sEvent,fn){if(obj.attachEvent){ obj.attachEvent("on"+sEvent,fn); }else{ obj.addEventListener(sEvent,fn,false); } }
function addEvent(el, type, fn){ if(el.attachEvent){ el['e’+type+fn] = fn;el[type+fn] = function(){ el[‘e’+type+fn](window.event);} el.attachEvent(‘on’+type, el[type+fn]);} else el.addEventListener(type, fn, false);} addEvent(window, 'load', init);...
event:事件名称(如 "click"、"mouseover" 等),不需要加 "on" 前缀。 function:事件触发时执行的回调函数。 useCapture(可选):布尔值,表示事件是否在捕获阶段执行,默认为false(即在冒泡阶段执行)。 优势 多个监听器:可以为同一个元素的同一个事件添加多个监听器,而不会互相覆盖。
