问题描述

我正在尝试使用jQuery更改CSS:

I am trying to change the CSS using jQuery:

$(init);

function init() {
    $("h1").css("backgroundColor", "yellow");
    $("#myParagraph").css({"backgroundColor":"black","color":"white");
    $(".bordered").css("border", "1px solid black");
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.0/jquery.min.js"></script>
<div class="bordered">
    <h1>Header</h1>
    <p id="myParagraph">This is some paragraph text</p>
</div>

我在这里缺少什么?

推荐答案

忽略那些暗示属性名称是问题。 jQuery API明确声明可以接受任何表示法:

Ignore the people that are suggesting that the property name is the issue. The jQuery API explicitly states that either notation is acceptable: http://api.jquery.com/css/

实际问题是你在这一行上缺少一个近大括号:

The actual problem is that you are missing a close curly brace on this line:

$("#myParagraph").css({"backgroundColor":"black","color":"white"});

将其更改为:

$("#myParagraph").css({"backgroundColor": "black", "color": "white"});

这是一个有效的演示:

Here's a working demo: http://jsfiddle.net/YPYz8/

$(init);

function init() {
    $("h1").css("backgroundColor", "yellow");
    $("#myParagraph").css({ "backgroundColor": "black", "color": "white" });
    $(".bordered").css("border", "1px solid black");
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.0/jquery.min.js"></script>
<div class="bordered">
    <h1>Header</h1>
    <p id="myParagraph">This is some paragraph text</p>
</div>
