1、什么是javaScript?
2、javaScript 的特点
<button onclick="myClick()">鼠标单击</button> <button ondblclick="myDBClick()">鼠标双击</button> <button onmousedown="myMouseDown()" onmouseup="myMouseUp()">鼠标按下和抬起</button> <button onmouseover="myMouseOver()" onmouseout="myMouseOut()">鼠标悬浮和离开</button> <button onmousemove="myMouseMove()">鼠标移动</button> <button onmouseenter="myMouseEnter()" onmouseleave="myMouseLeave()">鼠标进入和离开</button> <script> function myClick() { console.log("你单击了按钮！"); } function myDBClick() { console.log("你双击了按钮！"); } function myMouseDown() { console.log("鼠标按下了！"); } function myMouseUp() { console.log("鼠标抬起了！"); } function myMouseOver() { console.log("鼠标悬浮！"); } function myMouseOut() { console.log("鼠标离开！") } function myMouseMove() { console.log("鼠标移动！") } function myMouseEnter() { console.log("鼠标进入！") } function myMouseLeave() { console.log("鼠标离开！") }
2）键盘事件
keydown：按键按下
keyup：按键抬起
keypress：按键按下抬起
<body> <input id="name" type="text" onkeydown="myKeyDown(this.id)" onkeyup="myKeyUp(this.id)"> </body> <script> /*输出输入的字符*/ function myKeyDown(id) { console.log(document.getElementById(id).value); } /*按键结束，字体转换为大写*/ function myKeyUp(id) { var text = document.getElementById(id).value; document.getElementById(id).value = text.toUpperCase(); } </script>
