我有一个PDF,我通过PDFtoHTML来创建一个我可以操作的HTML页面。我想根据单一颜色rgb(0,129,162)选择多个标题,因为这似乎是区分标题与文本其余部分的唯一可辨别方式。有一个样式元素将颜色应用于head元素中应用颜色的所有span和div元素。
span.cls_022{font-family:Arial,serif;font-size:11.1px;color:rgb(0, 129, 162);font-weight:normal;font-style:normal:text-decoration: none}
HTML如下所示:
<div style="left: 72.02px; top: 204.98px; position: absolute">
<div class="cls_022" style="left: 72.02px; top: 204.98px; position:absolute;">
<span class="cls_022">Text I'd like to select</span>
</div>
</div>
现在,我可以选择并返回包含
的span的样式元素document.getElementsByClassName("cls_022")[0].style.cssText
这将返回标签内的样式。
在开发工具中,我可以看到它的颜色属性为rgb(0,129,162),这就是我想用来选择和返回CSS COLOR PROPERTY的值。
有什么想法吗?

这可以达到你想要的效果:
var $carousel = $('.carousel');
var dirFlag = false;
setInterval(function(){
dirFlag = !dirFlag;
if(dirFlag == true) {
$carousel.carousel('next');
} else {
$carousel.carousel('prev');
}
}, 5000);
var elem = document.getElementsByClassName("cls_022")[1];
var cssColor = window.getComputedStyle(elem, null).getPropertyValue("color");
&#13;
var targetElems = document.querySelectorAll("span.cls_022");
//targetElems.forEach(el => console.log(el));
//console.log(targetElems); //<--- If there are no spans with other color, and this is what you want, querySelectorAll return a NodeList.
let blueTitles = [];
targetElems.forEach(el => {
if(window.getComputedStyle(el, null).getPropertyValue("color") === 'rgb(0, 129, 162)') {
blueTitles.push(el);
}
});
//console.log(blueTitles); // <---- blueTitles is an array only contains spans with class "cls_022" and color rgb(0, 129, 162)
&#13;
span.cls_022 {
font-family: Arial, serif;
font-size: 11.1px;
color: rgb(0, 129, 162);
font-weight: normal;
font-style: normal:text-decoration: none
}
span.red {
color: red;
}
