In JavaScript the keycodes property plays a pivotal role which returns the unicode character present as key value within that key code which gets triggered as soon as the event of onkeypress is made either with onkeyup or onkeydown button which in turn have a massive difference between themselve...
_keyCodeFromEvent(e) 根据键盘事件对象event获取对应按键的key code。 注意,这里并没有直接使用event.keyCode。原因是有些按键在不同浏览器中的event.keyCode值不一致,需要进行特殊处理。 function _keyCodeFromEvent(e) { var code = e.keyCode; // right command on webkit, command on gecko if (code == 93...
{key:character,code:'Key'+character.toUpperCase(),charCode:character.charCodeAt(0),keyCode:character.charCodeAt(0),bubbles:true});// 触发事件inputField.dispatchEvent(event);// 将字符添加到文本框inputField.value+=character;}
在ie中,当keypress事件发生时候,keyCode存放的是character code,当keydown和keyup发生时候, keyCode存放是按键值。 跨浏览器的书写方式是 var charCode = e.which || e.keyCode; 或更加精确的方式 var charCode = (typeof e.which == ‘number’) ? e.which : e.keyCode; 这里经常用到方法是将数字装换为...
WebKit has modified their Konqueror-derived code to use IE keycodes, and I expect Konqueror will follow. Thus there seems to be a convergences on the IE and Mozilla keycodes, which are pretty similar. This is kind of encouraging. On keydown and keyup, the event objects also have flags ...
keyCode 对于keypress 事件,该属性声明了被敲击的键生成的 Unicode 字符码。对于 keydown 和 keyup 事件,它指定了被敲击的键的虚拟键盘码。虚拟键盘码可能和使用的键盘的布局相关。 offsetX,offsetY 发生事件的地点在事件源元素的坐标系统中的 x 坐标和 y 坐标。 returnValue 如果设置了该属性,它的值比事件句柄...
