blocks|key|3180790|text|这里有一些技巧，因为在设置strokeStyle和fillStyle等特定属性时，HTML5画布需要解析颜色值：|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|3180791|var+ctx+=+document.createElement('canvas').getContext('2d');
ctx.strokeStyle+=+'rgb(64,+128,+192)';
var+hexColor+=+ctx.strokeStyle;|code-block|syntax|javascript|3180792|entityMap^0|D|B|P|9|0|0^^$0|@$1|2|3|4|5|6|7|M|8|@$9|N|A|O|B|C]|$9|P|A|Q|B|C]]|D|@]|E|$]]|$1|F|3|G|5|H|7|R|8|@]|D|@]|E|$I|J]]|$1|K|3|-4|5|6|7|S|8|@]|D|@]|E|$]]]|L|$]]

<p>There's a bit of a hack for this, since the HTML5 canvas is required to parse color values when certain properties like <code>strokeStyle</code> and <code>fillStyle</code> are set:</p>

<pre><code>var ctx = document.createElement('canvas').getContext('2d');
ctx.strokeStyle = 'rgb(64, 128, 192)';
var hexColor = ctx.strokeStyle;
</code></pre>

blocks|key|266784|text|事实上，如果在某些元素下没有定义background-color，Chrome会将其background-color输出为rgba(0,+0,+0,+0)，而Firefox输出为transparent。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|266785|entityMap^0|G|G|16|G|1P|G|2H|B|0^^$0|@$1|2|3|4|5|6|7|H|8|@$9|I|A|J|B|C]|$9|K|A|L|B|C]|$9|M|A|N|B|C]|$9|O|A|P|B|C]]|D|@]|E|$]]|$1|F|3|-4|5|6|7|Q|8|@]|D|@]|E|$]]]|G|$]]

<p>In fact, if there is no definition of <code>background-color</code> under some element, Chrome will output its <code>background-color</code> as <code>rgba(0, 0, 0, 0)</code>, while Firefox outputs is <code>transparent</code>.</p>

<p><strong>HTML</strong></p>

<pre><code>&lt;div style="background-color:#f5b405"&gt;&lt;/div&gt;

<p><strong>jQuery</strong></p>

<pre><code>$(this).attr("style").replace("background-color:", "");

blocks|key|2967056|text|添加@Newred解决方案。如果你的风格不仅仅是background-color，你可以使用下面的代码：|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|2967057|$(this).attr('style').split(';').filter(item+=>+item.startsWith('background-color'))[0].split(":")[1]|code-block|syntax|javascript|2967058|entityMap^0|O|G|0|0^^$0|@$1|2|3|4|5|6|7|M|8|@$9|N|A|O|B|C]]|D|@]|E|$]]|$1|F|3|G|5|H|7|P|8|@]|D|@]|E|$I|J]]|$1|K|3|-4|5|6|7|Q|8|@]|D|@]|E|$]]]|L|$]]

<p>Adding on @Newred solution.
If your style has more than just the <code>background-color</code> you can use this:</p>

<pre><code>$(this).attr('style').split(';').filter(item =&gt; item.startsWith('background-color'))[0].split(":")[1]
</code></pre>


blocks|key|270474|text|这个解决方案利用了@Newred和@Radu+Diță所说的部分内容。但在不太标准的情况下会起作用。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|270475|+$(this).attr('style').split(';').filter(item+=>+item.startsWith('background-color'))[0].split(":")[1].replace(/\s/g,+'');|code-block|syntax|javascript|270476|它们都有的问题是都没有检查背景颜色和颜色之间的空格。|270477|所有这些都将与上面的代码匹配。|270478|+background-color:+#ffffff
+background-color:++++++#fffff;
+background-color:#fffff;|270479|entityMap^0|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|O|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|P|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|Q|8|@]|9|@]|A|$]]|$1|I|3|J|5|6|7|R|8|@]|9|@]|A|$]]|$1|K|3|L|5|D|7|S|8|@]|9|@]|A|$E|F]]|$1|M|3|-4|5|6|7|T|8|@]|9|@]|A|$]]]|N|$]]

<p>This Solution utilizes part of what @Newred and @Radu Diță said.  But will work in less standard cases.</p>

<pre><code> $(this).attr('style').split(';').filter(item =&gt; item.startsWith('background-color'))[0].split(":")[1].replace(/\s/g, '');
</code></pre>

<p>The issue both of them have is that neither check for a space between background-color:  and the color. </p>

<p>All of these will match with the above code.</p>

<pre><code> background-color: #ffffff
 background-color:      #fffff;
 background-color:#fffff;
</code></pre>
