這節(jié)課主要復(fù)習(xí)了前面所學(xué)的知識有:
js用id名稱綁定元素;document.getElementById("box")
函數(shù)的聲明;function (){}
js控制css樣式;js綁定的元素.style.css樣式=“屬性值”
事件驅(qū)動函數(shù);onclick=“函數(shù)名+()”
練習(xí)效果:
代碼:
<!DOCTYPE html> <html> <head> <title>Document</title> <style> #box { width: 200px; height: 200px; background: red; margin: 0 auto; transition: 0.5s; } input { display: block; border: 2px solid green; } #btn { float: left; } </style> </head> <body> <div id="btn"> <input type="button" value="變寬" onclick="wit()" /> <input type="button" value="變高" onclick="hei()" /> <input type="button" value="變圓" onclick="rad()" /> <input type="button" value="變藍" onclick="cor()" /> <input type="button" value="隱藏" onclick="hid()" /> <input type="button" value="顯示" onclick="dis()" /> <input type="button" value="重置" onclick="set()" /> </div> <div id="box"></div> <script> var obox; window.onload = function() { obox = document.getElementById("box"); }; function wit() { obox.style.width = "300px"; //寬度變?yōu)?00px; } function hei() { obox.style.height = "300px"; //高度變?yōu)?00px; } function rad() { obox.style.borderRadius = "50%"; //寬度變?yōu)?00px; } function cor() { obox.style.background = "blue"; //寬度變?yōu)?00px; } function hid() { obox.style.display = "none"; //寬度變?yōu)?00px; } function dis() { obox.style.display = "block"; //寬度變?yōu)?00px; } function set() { //重置所有屬性 obox.style.display = "block"; obox.style.width = "200px"; obox.style.height = "200px"; obox.style.background = "red"; obox.style.borderRadius = "0"; } </script> </body> </html>
