淘宝网站建设的主要工作建一个网站需要什么条件

1、思路

1、在登录页面需要启动向右滑块验证

2、效果图

3、文章地址：滑动验证码的实现-vue-simple-verify

2、成分分析

1、由三块构成，分别是底部条、拖动条、拖动移动部分

2、底部条：整体容器，包括背景、边框和文字（请按住滑块，拖动到最右边）

3、拖动条：图片+边框+背景色即可

4、完成部分：背景、边框和文字（验证完成）

3、事件分析

1、鼠标按下事件：记录鼠标位置以及状态

2、鼠标移动事件：计算滑块位置

3、鼠标离开事件：更新状态至初始状态

4、鼠标抬起事件：更新状态至初始状态

4、效果图

5、代码

1、SlideVerify.vue文件

<template><divref="sliderContainer"@mousemove="onMouseMove"@mouseup="onMouseUp"class="slider-verify-container"@mouseleave="onMouseLeave"><span v-if="blockState === 0">请按住滑块，拖动到最右边</span><div@mousedown="onMouseDown":style="{ left: leftP }"class="slider-verify-block"/><div :style="{ width: leftP }" class="slider-verify-complete"><span v-if="blockState === 2">验证成功</span></div></div>
</template><script setup>
import { ref, defineEmits } from "vue";const emit = defineEmits(["success", "failed"]);const leftP = ref("0");const blockState = ref(0);const startP = ref(undefined);const sliderContainer = ref(undefined);
const onMouseDown = (e) => {if (blockState.value !== 2) {leftP.value = "0";blockState.value = 1;startP.value = {clientX: e.clientX,};} else {leftP.value = "0";blockState.value = 0;}
};
const onMouseMove = (e) => {if (blockState.value === 1) {let width = e.clientX - startP.value.clientX;if (width + 56 > 400) {leftP.value = 400 - 56 + "px";blockState.value = 2;emit("success");} else {leftP.value = width + "px";}}
};
const onMouseUp = (e) => {if (blockState.value !== 2) {leftP.value = "0";blockState.value = 0;emit("failed");}
};
const onMouseLeave = (e) => {if (blockState.value !== 2) {leftP.value = "0";blockState.value = 0;emit("failed");}
};
</script><style lang="scss" scoped>
.slider-verify-container {width: 100%;height: 56px;background-color: transparent;position: relative;border: solid 1px #20cccf;text-align: center;color: #20cccf;line-height: 56px;user-select: none;-moz-user-select: none;-ms-user-select: none;-webkit-user-select: none;
}
.slider-verify-complete {width: 0;height: 56px;position: absolute;background-color: #00e6f14f;left: 0;top: 0;
}
.slider-verify-block {width: 56px;height: 56px;background-image: url("@/assets/images/login6/arrow.png");background-color: white;position: absolute;left: 0;top: -1px;border: solid 1px #20cccf;background-size: 50%;background-repeat: no-repeat;background-position: center;
}
</style>

2、调用代码

<slide-verify @success="onVerifySuccess" @failed="onVerifyFailed" />
