<el-select v-model="form.sprojectName" placeholder="请选择比赛项目" class="width_100" @change="projectChange" > <el-option v-for="item in projectList" :key="item.id" :label="item.label" :value="item.id" > </el-option> </el-select> 怎么获取change事件的id和label值?

可以在`change`事件中传入一个参数,这个参数就是选中的option对应的对象,其中包含了`id`和`label`属性,可以通过这两个属性来获取id和label值。代码示例如下:
```
projectChange(selectedOption) {
const id = selectedOption.id;
const label = selectedOption.label;
// 进行后续操作
}
```

您可以使用以下CSS样式来设置el-select的选中文字样式:
```css
/* 设置选中的文字颜色为红色 */
.el-select .el-select-dropdown__item.selected {
color: red;
}
```
您可以将此样式添加到您的CSS样式表文件中,或者将其添加到页面的style标签中。这样,在el-select中选中的文字就会显示为红色。
