根据提供的引用内容,问题是关于属性"labelWidth"的类型检查失败的问题。错误信息是"Invalid prop: type check failed for prop "labelWidth". Expected String with value "100", got Number with value 100"。根据引用和引用,我们可以看到,在使用Element UI的表单元素时,它对于一些属性的类型有要求,例如"labelWidth"属性的类型需要是字符串。而在引用中的代码中,我们可以看到在构建对象时,有一个属性值没有被转换成字符串格式,导致了类型检查失败的错误。
解决这个问题的方法是将"labelWidth"属性的值转换为字符串格式。例如,在模板中使用字符串拼接或者使用toString()方法将其转换为字符串。这样,在传递给组件时,就满足了类型检查的要求。
举例来说,你可以将代码修改为以下形式:
```
<el-form-item :label="'index 1 ' + labelWidth.toString()" v-for="(item,index) in intro" :key="index 1"></el-form-item>
```
或者
```
<el-form-item :label="`index 1 ${labelWidth}`" v-for="(item,index) in intro" :key="index 1"></el-form-item>
```
这样,你就能避免类型检查失败的错误。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
