jQuery 的css()方法用來設定或讀取HTML元素的css屬性。
讀取元素的CSS語法語法如下:
css(“propertyname“);
例如下面程式碼取得第一個
元素的背景顏色。
[javascript]
$("p").css("background-color");
$("p").語法來設定HTML元素的CSS屬性:
css(“propertyname“,”value“);
例如,下面程式碼為所有
元素設定背景色為黃色。
[html] <!DOCTYPE html> <html> <head> <meta charset="utf-8"> <title>JQuery Demo</title> <script src="scripts/jquery-1.9.1.js"></script> <script> $(document).ready(function () { $("button").click(function () { $("p").css("background-color", "yellow"); }); }); </script> </head> <body> <h2>This is a heading</h2> <p style="background-color: #ff0000">This is a paragraph.</p> <p style="background-color: #00ff00">This is a paragraph.</p> <p style="background-color: #0000ff">This is a paragraph.</p> <p>This is a paragraph.</p> <button>Set background-color of p</button> </body> </html> <!DOCTYPE html> <html> <head> <meta charset="utf-8"> <title>JQuery Demo</title> <script src="scripts/jquery-1.9.1.js"></script> <script> $(document).ready(function () { $("button").click(function () { $("p").css("background-color", "yellow"); }); }); </script> </head> <body> <h2>This is a heading</h2> <p style="background-color: #ff0000">This is a paragraph.</p> <p style="background-color: #00ff00">This is a paragraph.</p> <p style="background-color: #0000ff">This is a paragraph.</p> <p>This is a paragraph.</p>www.2cto.com <button>Set background-color of p</button> </body> </html>css()也支援同時多個CSS屬性:其語法如下:
css({“propertyname“:”value“,”propertyname“:”value“,…});
例如:
[javascript] view plaincopyprint?
$("p").css({"background-color":"yellow","font-size":"200%"}); p").css({"background-color":"yellow","font-size":"200%"});
