在Vue项目中,我试图返回一组工具中每个工具的URL。
这是ToolDetails.vue
文件中的相关代码段:
<script>
import { mapActions } from 'vuex';
import ToolFacts from '@/components/ToolFacts.vue';
import Matrix from '@/components/Matrix.vue';
import json from '../../models/content/tool_details.json';
export default {
name: 'tool-details',
components: {
ToolFacts,
Matrix,
},
data: () => ({
// tool: '',
}),
created() {
this.checkValidToolName();
// this.getToolName();
},
computed: {
tool() {
// eslint-disable-next-line
return Object.values(json).find(entity => entity.tool_url.toLowerCase() === this.$route.params.name.toLowerCase());
},
},
methods: {
getToolName() {
this.tool = json[this.$route.params.name];
// eslint-disable-next-line
return Object.values(json).for.find(entity => entity.tool_url.toLowerCase() === this.$route.params.name.toLowerCase());
},
getAssetPath(assetPath) {
// eslint-disable-next-line
return require(`../assets/${assetPath}`);
},
...mapActions(['SET_PRESELECTED_TOOL']),
compareTool() {
this.SET_PRESELECTED_TOOL(this.tool.name)
.then(this.$router.push('/compare'));
},
checkValidToolName() {
if (!this.tool) {
this.$router.push('/filter');
}
},
},
};
</script>
tool_details.json
的格式如下:
{
"Example Tool": {
"name": "Example Tool Name",
"tool_url": "example-tool-url",
...
},
...
}
URL在浏览器源代码中生成为undefined
,并且控制台显示此错误:
vue.runtime.esm.js:619 [Vue warn]: Error in render: "TypeError: Cannot read property 'toLowerCase' of undefined"
found in
---> <ToolDetails> at src/views/ToolDetails.vue
<App> at src/App.vue

当我放入调试器时,将定义json
而不是entity
。
我尝试过这样定义entity
:
const entity = [];
这:
const entity = {};
但是我收到相同的控制台错误以及ES Lint错误:
'entity' is assigned a value but never used
如何解决该控制台错误以为每个工具返回正确的URL?
答案 0 :(得分:0)
此问题已解决。显然,此问题是由另一个文件ToolCard.vue
引起的,该文件包含以下内容:
<div class="learn-cta">
<router-link tag="a" :to="`tool/${data.tool_url}`">
Learn More
</router-link>
<img src="@/assets/icons/arrow_blue.svg" />
</div>
引用tool_cards.json
,在其中我需要添加一个tool_url
行。这样就可以为每个工具链接正确生成URL,并且undefined
错误消失了。
