使用CSS/JavaScript更改剑道图工具提示文本颜色

Change Kendo Chart tooltip text color using CSS/JavaScript

本文关键字：工具提示文本颜色 CSS JavaScript 使用更新时间：2023-09-26

我的图表工具提示的所有文本颜色都是黑色，这与我的图表颜色不太匹配。我一直在尝试使用CSS将颜色更改为白色，但不知怎么的，它没有改变。

我正在寻找一种将颜色应用于屏幕上所有图表的解决方案。

检查其中一个工具提示的元素源，可以看到：

<div class="k-tooltip k-chart-tooltip" style="font: 12px/normal Arial,Helvetica,sans-serif; border: 1px solid rgb(255, 0, 0); border-image: none; left: 497px; top: 368px; position: absolute; font-size-adjust: none; font-stretch: normal; opacity: 1; background-color: rgb(255, 0, 0);">70.25%</div>

我试过一些东西，比如：

.k-chart .k-tooltip {
    color: white !important;
}
.k-tooltip.k-chart-tooltip {
    color: white !important;
}
.k-chart-tooltip {
    color: white !important;
}

使用CSS，设置这个类来设置的样式

.k-tooltip,.k-chart-tooltip
{
     color: white;
}

或

使用jQuery，您可以设置剑道图工具提示的颜色，就像使用mvc包装器一样JSFiddle
