jQuery 的css()方法用来设置或读取HTML元素的css属性。
读取元素的CSS语法语法如下:
css(“propertyname“);
比如下面代码取得第一个e388a4556c0f65e1904146cc1a846bee元素的背景颜色。
[javascript]
$("p").css("background-color");
$("p").css("background-color");
使用下面的语法来设置HTML元素的CSS属性:
css(“propertyname“,”value“);
例如,下面代码为所有e388a4556c0f65e1904146cc1a846bee元素设置背景色为黄色。
[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()也支持同时多个CSS属性:其语法如下:
css({“propertyname“:”value“,”propertyname“:”value“,…});
比如:
[javascript] view plaincopyprint?
$("p").css({"background-color":"yellow","font-size":"200%"});
$("p").css({"background-color":"yellow","font-size":"200%"});
