根据提供的引用内容,您提供的是一个Python格式化字符串的示例。下面是一个类似的示例:
```python
page = 10
category = 1
resolution = 2
color = 1
categoryId = 5
ratio = 0.5
formatted_string = f'{{"size": {page},"current": 2,"sort": 0,"category": {category},"resolution": {resolution},"color": {color},"categoryId": {categoryId},"ratio": {ratio}}}'
print(formatted_string)
```
输出结果为:
```
{"size": 10,current": 2,"sort": 0,"category": 1,"resolution": 2,"color": 1,"categoryId": 5,"ratio": 0.5}
```
这个示例中,我们使用了f-string来格式化字符串,并在字符串中插入了变量。在这个例子中,我们使用了变量page、category、resolution、color、categoryId和ratio,并将它们插入到字符串中的相应位置。

后端返回给我categoryId是17 我要从category:[{name:'张三',categoryId:17},{name:'张三',categoryId:18},{name:'张三',categoryId:19},{name:'张三',categoryId:20}]找到id是17的数据 把他的name渲染到 <el-form-item label="商品类目" prop="categoryId"> <el-select @focus="open" v-model="form.categoryId" filterable clearable placeholder="请选择商品类目" > <el-option v-for="item in category" :key="item.categoryId" :label="item.name" :value="item.categoryId" > </el-option> </el-select> </el-form-item>中的select 并且v-model绑定这个id 怎么做 同时我 data() { return { // 表单信息 form: { title: "", smallTitle: "", categoryId: "", manImage: [], dataUrl: [], skuList: [ { name: "", size: "", price: "", stock: "", attributeurl: "" }, ], },}
你可以使用 Array.prototype.find() 方法来查找对应的数据,并将其渲染到表单中。同时,你需要将 `form.categoryId` 的值设为对应的 `categoryId`,以便表单能够正确提交。下面是示例代码:
```
data() {
return {
// 表单信息
form: {
title: "",
smallTitle: "",
categoryId: "",
manImage: [],
dataUrl: [],
skuList: [
{ name: "", size: "", price: "", stock: "", attributeurl: "" },
],
},
category: [
{ name: '张三', categoryId: 17 },
{ name: '张三', categoryId: 18 },
{ name: '张三', categoryId: 19 },
{ name: '张三', categoryId: 20 },
],
};
},
methods: {
open() {
// 查找对应的数据
const category = this.category.find(item => item.categoryId === 17);
// 渲染到表单中
this.form.categoryId = category.categoryId;
this.form.categoryName = category.name;
}
}
```
在上面的代码中,`open()` 方法是在表单的 select 控件获得焦点时触发的。你可以根据实际需求来触发该方法。另外,你需要将 `categoryName` 添加到表单信息中,并在模板中使用它来渲染 select 控件的 label。
我要从category:[{name:'张三',categoryId:17},{name:'张三',categoryId:18},{name:'张三',categoryId:19},{name:'张三',categoryId:20}]找到id是17的数据 把他的name渲染到 <el-form ref="form" :rules="rules" :model="form" label-width="80px"> <el-form-item label="商品类目" prop="categoryId"> <el-select @focus="open" v-model="form.categoryId" filterable clearable placeholder="请选择商品类目" > <el-option v-for="item in category" :key="item.categoryId" :label="item.name" :value="item.categoryId" > </el-option> </el-select> </el-form-item> </el-form> 中的select 并且v-model绑定这个id 怎么做 同时我 data() { return { // 表单信息 form: { title: "", smallTitle: "", categoryId: "", manImage: [], dataUrl: [], skuList: [ { name: "", size: "", price: "", stock: "", attributeurl: "" }, ], },}
你可以通过以下代码实现:
```
// 在 mounted 钩子函数中获取数据并渲染到页面上
mounted() {
// 模拟异步请求数据
setTimeout(() => {
const data = [{name:'张三',categoryId:17},{name:'张三',categoryId:18},{name:'张三',categoryId:19},{name:'张三',categoryId:20}]
const item = data.find(item => item.categoryId === 17)
this.form.categoryId = item.categoryId
this.form.categoryName = item.name
}, 1000)
},
```
同时,你需要在 `form` 对象中添加一个 `categoryName` 属性来保存选中的类目名称,然后在 `<el-select>` 组件中使用 `categoryName` 属性来渲染选中的类目名称。
```
<el-form ref="form" :rules="rules" :model="form" label-width="80px">
<el-form-item label="商品类目" prop="categoryId">
<el-select @focus="open" v-model="form.categoryId" filterable clearable placeholder="请选择商品类目" >
<el-option :key="item.categoryId" :label="item.name" :value="item.categoryId" v-for="item in category"></el-option>
</el-select>
<div slot="suffix">{{ form.categoryName }}</div>
</el-form-item>
</el-form>
```
