【HarmonyOS】【ArkUI】鸿蒙 linear-gradient 来实现渐变色，怎么动态设置呢？尝试了一下，供大家参考

​

 JS方式实现文本或按钮背景渐变色

 

我们可以参考HarmonyOS linear-gradient 

​

 

如下是动态设置代码

hml

<div class="container">
    <text class="title"
          style="background:{{mbackground}}">
        {{ $t('strings.hello') }} {{ title }}
    </text>
</div>

 

css

.container {
    flex-direction: column;
    justify-content: center;
    align-items: center;
    width: 100%;
    height: 100%;
    background-color: white;
}
 
.title {
    font-size: 40px;
    color: #000000;
    opacity: 0.9;
}

 

Js

export default {

    data: {

        title: "",

        mbackground:"{ \"values\":[{\"type\":\"linearGradient\",\"directions\":[\"to\",\"bottom\"],\"values\":[\"rgb(255,0,0)\",\"rgb(0,0,255)\"]}]}"

    },

    onInit() {

        this.title = this.$t('strings.world');

    },

}

 

 

效果图如下
