""" 把列表中所有人名的*去掉,比方: Tenc*ent--> Tencent """ name=['Tenc*ent', 'Zhi*hu', 'Bai*du'] # 代码中要用到lambda函数

你可以使用`map`函数结合`lambda`函数来实现去除列表中所有人名中的星号。下面是一个示例代码:
```python
name = ['Tenc*ent', 'Zhi*hu', 'Bai*du']
result = list(map(lambda x: x.replace('*', ''), name))
print(result)
```
输出结果:
```
['Tencent', 'Zhihu', 'Baidu']
```
在这个示例中,`map`函数将`lambda`函数应用到列表`name`的每个元素上。`lambda`函数使用`replace`方法将星号替换为空字符串,从而去除了所有人名中的星号。最后,通过`list`函数将`map`返回的迭代器转换为列表并打印结果。

在这段代码中,按钮的高亮通过 `:class` 绑定和 `activeButton` 数据来控制。具体步骤如下:
1. 在 Vue 组件的 `data` 中定义一个 `activeButton` 属性,用于跟踪当前高亮的按钮:
```javascript
export default {
data() {
return {
activeButton: '1m' // 初始化为默认高亮的按钮值
}
},
// ...
}
```
2. 在模板中使用 `:class` 绑定来设置按钮的样式,并使用条件判断 `activeButton === '按钮值'` 来决定是否添加 `active` 类:
```html
<template>
<div class="main-kline-cycle">
<el-button type="info" :class="{ active: activeButton === '1m' }" @click="handleButtonClick('1m')">1m</el-button>
<el-button type="info" :class="{ active: activeButton === '5m' }" @click="handleButtonClick('5m')">5m</el-button>
<el-button type="info" :class="{ active: activeButton === '30m' }" @click="handleButtonClick('30m')">30m</el-button>
<el-button type="info" :class="{ active: activeButton === '1h' }" @click="handleButtonClick('1h')">1h</el-button>
<el-button type="info" :class="{ active: activeButton === '4h' }" @click="handleButtonClick('4h')">4h</el-button>
<el-button type="info" :class="{ active: activeButton === '1d' }" @click="handleButtonClick('1d')">1d</el-button>
<el-button type="info" :class="{ active: activeButton === '1w' }" @click="handleButtonClick('1w')">1w</el-button>
</div>
</template>
```
3. 在方法中定义 `handleButtonClick`,用于更新 `activeButton` 的值:
```javascript
export default {
// ...
methods: {
handleButtonClick(buttonValue) {
this.activeButton = buttonValue;
}
}
}
```
这样,当按钮被点击时,`activeButton` 的值会更新,从而改变按钮的高亮状态。你可以根据实际需求修改样式和按钮的值。
<div> <el-dialog title="提示" :visible.sync="dialogShowSetting" :before-close="handleClose"> <span>这是一段信息</span> <span slot="footer" class="dialog-footer"> <el-button @click="dialogShowSetting = false">取 消</el-button> <el-button type="primary" @click="dialogShowSetting = false">确 定</el-button> </span> </el-dialog> </div> data() { var that = this; return { cycle: '1m', show: false, activeButton: '', dialogShowSetting: false, } methods: { handleClose(done) { this.$confirm('确认关闭?') .then(_ => { // 关闭方法-上方传的参数done done(); }) .catch(_ => { }); }, }
根据您提供的代码,我注意到在您的data选项中,属性和方法之间缺少逗号,这可能导致代码出现语法错误。请修改您的代码如下:
```javascript
data() {
var that = this;
return {
cycle: '1m',
show: false,
activeButton: '',
dialogShowSetting: false
};
},
methods: {
handleClose(done) {
this.$confirm('确认关闭?')
.then(_ => {
// 关闭方法-上方传的参数done
done();
})
.catch(_ => { });
}
}
```
请注意,属性和方法之间需要使用逗号进行分隔。如果您的代码中还有其他地方存在问题,请提供更多的上下文信息,我会尽力帮助您解决问题。
