jquery - 删除 awesoplete 插件中的突出显示 CSS

Question

我正在使用这个插件，非常棒。我想做的是删除与您已经输入的字母一起弹出的黄色突出显示。例如http://jsfiddle.net/kohenkatz/fmgh29qo/2/在文本框中开始输入 Java 一词，您将看到下拉列表突出显示这些字母。如何删除该突出显示？

编辑:http://jsfiddle.net/fmgh29qo/10/

开始在第一个选项上输入“Ja”，它是正确的，但它后面有一个黄色的小矩形，我试图将其删除。然后，在第二个选项上，当您将鼠标悬停在第二个选项上时，它会自动将“ja”变成白色。有人可以帮我吗？

您可以通过添加 <mark> 的样式来更改它元素，例如:

mark{
    background-color:transparent !important;
    padding:0;
    margin:0;
}
