基础用法

<template>
    <SliderCaptcha
        :background="bgImage"
        :block="blockImage"
        :verify="handleVerify"
        @success="onSuccess"
        @fail="onFail"
        @change="onChange"
    />
</template>

<script setup lang="ts">
import { SliderCaptcha } from "@punish/slider-captcha";
import type { SliderCaptchaTrackItem } from "@punish/slider-captcha";

const bgImage = "https://example.com/bg.jpg"; // 应从服务端获取
const blockImage = "https://example.com/block.png"; // 应从服务端获取

const handleVerify = async (last: SliderCaptchaTrackItem) => {
    // 自定义验证逻辑，返回 true/false
    return last.xPercent > 80; // 应 请求 服务端接口 , 将 last.xPercent 作为参数 （也可能包含其他 服务端所需要的额外数据）， 根据服务端验证结果 返回 true/false。 true 表示验证成功，false 表示验证失败。
};

const onSuccess = () => {
    console.log("验证成功");
};

const onFail = () => {
    console.log("验证失败");
};

const onChange = (tracks: SliderCaptchaTrackItem[]) => {
    console.log("滑动轨迹:", tracks);
};
</script>

方法

通过 ref 获取组件实例后，可调用以下方法：

<template>
    <SliderCaptcha ref="captchaRef" :background="bg" :block="block" :verify="verify" />
    <button @click="handleReset">重置</button>
</template>

<script setup lang="ts">
import { ref } from "vue";
import { SliderCaptcha } from "@punish/slider-captcha";

const captchaRef = ref();

const handleReset = () => {
    captchaRef.value?.reset();
};
</script>

自定义样式示例

<template>
    <div style="position: relative; width: 600px; margin: 0 auto">
        <SliderCaptcha
            ref="captchaRef"
            :background="captchaData.backgroundImage"
            :block="captchaData.sliderImage"
            :verify="verifyCaptcha"
            track-bg="#65CD81"
            track-thumb-class="track-thumb"
            track-class="track"
            @success="onVerifySuccess"
        >
            <template #default>
                
            </template>
        </SliderCaptcha>
        <Loading :visible="captchaVerifying" dot-color="red" dot-size="60px" dot-gap="60px" amplitude="80px" />
    </div>
</template>

<script setup>
import { Loading } from "@a-drowned-fish/rox-v";
import { SliderCaptcha } from "@punish/slider-captcha";

interface CaptchaInfo {
    backgroundImage: string;
    captchaId: string;
    sliderImage: string;
}

const captchaData = ref<CaptchaInfo | undefined>(undefined);
const captchaVerifying = ref(false);
const captchaRef = useTemplateRef("captchaRef");

onMounted(() => {
    fetch("https://mock.presstime.cn/mock/69d8c8165c2cd2d31df6900c/api/captcha")
        .then((response) => response.json())
        .then((response) => (captchaData.value = response?.data));
});

const verifyCaptcha = async (option: SliderCaptchaTrackItem) => {
    captchaVerifying.value = true;
    return fetch("https://mock.presstime.cn/mock/69d8c8165c2cd2d31df6900c/api/verify")
        .then((response) => response.json())
        .then((response) => response?.data?.passed)
        .finally(() => (captchaVerifying.value = false));
};

const onVerifySuccess = () => {
    alert("验证成功");
    captchaRef.value?.reset();
};
