Vue JS-使用innerHTML渲染的动态创建的组件无法绑定到事件

Ben

我最近才刚开始涉足Vue JS-到目前为止很喜欢。我现在遇到一个问题,我试图创建一个(非平凡的)表(使用vue-good-table插件),其中每个单元格都是一个单独的组件。

阅读了插件的文档后,有人提到可以创建一个HTML列类型,在其中您可以使用原始HTML(我想):https : //xaksis.github.io/vue-good- table / guide / configuration / column-options.html#html

为简化起见,这就是我所拥有的-包含表的Vue组件(称为Dashboard2.vue)和名为Test.vue的子组件

我正在为每个相关单元动态创建Test组件,并将其分配给相关行单元。由于已将列定义为HTML类型,因此我使用innerHTML属性从Vue组件中提取原始HTML。(遵循本文https://css-tricks.com/creating-vue-js-component-instances-programmatically/)一切进展顺利,仪表板看起来完全像我想要的那样,但是当单击内部按钮时每个测试组件都没有任何反应。

我怀疑由于我已经使用了innerHTML属性,所以它只是以某种方式跳过了Vue甚至是处理程序机制,所以我有点卡住了。

这是相关的组件部分:

Dashboard2.vue:

<template>
  <div>
    <vue-good-table
      :columns="columns"
      :rows="rows"
      :search-options="{enabled: true}"
      styleClass="vgt-table condensed bordered"
      max-height="700px"
      :fixed-header="true"
      theme="black-rhino">
    </vue-good-table>
  </div>
</template>

<script>
import axios from 'axios';
import Vue from 'vue';
import { serverURL } from './Config.vue';
import Test from './Test.vue';

export default {
  name: 'Dashboard2',
  data() {
    return {

      lastXBuilds: 7,
      builds: [],
      columns: [
        {
          label: 'Test Name',
          field: 'testName',
        },
      ],
      rows: [],
    };
  },
  methods: {
    fetchResults() {
      const path = `${serverURL}/builds?name=${this.jobName}&last_x_builds=${this.lastXBuilds}`;
      axios.get(path)
        .then((res) => {
          this.builds = res.data;
          this.builds.forEach(this.createColumnByBuildName);
          this.createTestsColumn();
          this.fillTable();
        })
        .catch((error) => {
          // eslint-disable-next-line no-console
          console.error(error);
        });
    },
    createBaseRow(build) {
      return {

        result: build.result,
      };
    },
    addChildRows(build, children) {
      const row = this.createBaseRow(build);
      // eslint-disable-next-line no-plusplus
      for (let i = 0; i < build.sub_builds.length; i++) {
        const currentBuild = build.sub_builds[i];
        if (currentBuild.name === '') {
          this.addChildRows(currentBuild, children);
        } else {
          children.push(this.addChildRows(currentBuild, children));
        }
      }
      return row;
    },
    createColumnByBuildName(build) {
      this.columns.push({ label: build.name, field: build.id, html: true });
    },
    addRow(build) {
      const row = this.createBaseRow(build);
      row.children = [];
      this.addChildRows(build, row.children);

      // eslint-disable-next-line no-plusplus
      for (let i = 0; i < row.children.length; i++) {
        this.rows.push({ testName: row.children[i].name });
      }
    },
    fillBuildColumn(build) {
      const row = this.createBaseRow(build);
      row.children = [];
      this.addChildRows(build, row.children);
      // eslint-disable-next-line no-plusplus
      for (let i = 0; i < row.children.length; i++) {
        const childBuild = row.children[i];
        const TestSlot = Vue.extend(Test);
        const instance = new TestSlot({
          propsData: {
            testName: childBuild.name,
            result: childBuild.result,
            runTime: childBuild.runtime.toString(),
            startTime: childBuild.startTime,
            estimatedRunTime: childBuild.estimatedRuntime.toString(),
          },
        });
        instance.$mount();
        this.rows[i] = Object.assign(this.rows[i], { [build.id]: instance.$el.innerHTML });
      }
    },
    fillTable() {
      this.builds.forEach(this.fillBuildColumn);
    },
  },
  created() {
    this.fetchResults();
  },
};
</script>

      alert('hi');
    },
  },
};
</script>

<style scoped>

我知道这是很多代码。特定的相关部分(在Dashboard2.vue中)是fillBuildColumn

再说一次-我是Vue JS的新手-据说我的直觉告诉我我在这里做错了很多事情。

任何帮助将不胜感激。

通过失去innerHTML属性和html类型,我最终得到一个:

浏览器抛出“ RangeError:超出最大调用堆栈大小”。不知道是什么原因造成的

我已经制作了一个CodeSandbox示例。我可能已经弄乱了数据部分。但这给出了想法。

fillBuildColumn(build) {
  const row = this.createBaseRow(build);
  row.children = [];
  this.addChildRows(build, row.children);
  // eslint-disable-next-line no-plusplus
  for (let i = 0; i < row.children.length; i++) {
    const childBuild = row.children[i];
// i might have messed up with the data here
    const propsData = {
      testName: childBuild.name,
      result: childBuild.result,
      runTime: childBuild.runtime.toString(),
      startTime: childBuild.startTime,
      estimatedRunTime: childBuild.estimatedRuntime.toString()
    };

    this.rows[i] = Object.assign(this.rows[i], {
      ...propsData
    });
  }
}

createColumnByBuildName(build) {
  this.columns.push({
    label: build.name,
    field: "build" + build.id //guessable column name
  });
}
<vue-good-table :columns="columns" :rows="rows">
  <template slot="table-row" slot-scope="props">
          <span v-if="props.column.field.startsWith('build')">
            <Cell
              :testName="props.row.testName"
              :build="props.row.build"
              :cluster="props.row.cluster"
              :startTime="props.row.startTime"
              :runTime="props.row.runTime"
              :estimatedRunTime="props.row.estimatedRunTime"
              :result="props.row.result"
            ></Cell>
          </span>
          <span v-else>{{props.formattedRow[props.column.field]}}</span>
        </template>
</vue-good-table>

这个想法是在模板内部渲染一个组件,并有条件地完成它。提供可猜测的列名称的原因是使用条件<span v-if="props.column.field.startsWith('build')">由于您只有1个静态字段,其余字段是动态的,因此也可以使用props.column.field !== 'testName'我在渲染时遇到问题,我不得不在全球范围内注册表格插件和Cell组件。
