我使用document.querySelectorAll("input[type='checkbox']");从DOM中获取所有复选框元素，并使用循环向每个复选框添加一个侦听器。selections对象可以跟踪已检查的项目。单击复选框时，项目值将按键添加到对象中。如果该复选框处于禁用状态，则会从对象中删除该项。无论何时发生操作，DOM都会根据select

listener: 在触发特定事件的时候打点; Exception: 在抛出异常的时候打点; Function: 在特定函数被调用的时候打点; debugger: 在书写的代码里希望打点的时候手动打点...禁用所有断点相当于把所有 checkbox 的勾都去掉; 停用当前断点会让浏览器忽略掉此断点,但是断点位置和图标仍然保留,以便再次激活使用; 移除断点会直接...
使用addEventListener()方法时,事件类型不应包括前缀“on”,比如:“onclick”改成“click”等。 addEventListener('click',listener,false); 注意:调用addEventListener()并不会影响onclick属性的值。 点击 var v = document.getElementById('mybutton'); v.onclick =function() {alert('1');} v.addEventListener...

target.addEventListener(type, listener[, useCapture]); 上面是使用格式,addEventListener方法接受三个参数。 type,事件名称,大小写不敏感。注意:事件名称是没有"on"开头的 listener,监听函数。指定事件发生时,会调用该监听函数。 useCapture,监听函数是否在捕获阶段(capture)触发。该参数是一个布尔值,默认为false(表示...
