httpget和post模板

一直用的hbuilder，到這裡發現怎麼設定也不生效，於是轉vscode了

new global snippets file，手工建立模板vue.config-snippets

模板內容

    "http-get請求": {
        "prefix": "httpget",
        "body": [
            "this.\\$http({",
            "url: this.\\$http.adornUrl(''),",
            "method: 'get',",
            "params: this.\\$http.adornParams({})",
            "}).then(({data}) => {",
            "})"
        ],
        "description": "httpGET請求"
    },
    "http-post請求": {
        "prefix": "httppost",
        "body": [
            "this.\\$http({",
            "url:this.\\$http.adornUrl(''),",
            "method: 'post',",
            "data: this.\\$http.adornData(data, false)",
            "}).then(({ data }) => { });"
        ],
        "description": " httpPOST請求"
    },
 

本節主要用到了

MessageBox 彈框

this.$confirm(`確認提示`, "提示", {
        confirmButtonText: "確定",
        cancelButtonText: "取消",
        type: "warning",
      })
     .then(() => {})
     .catch(() => {});

Message 訊息提示

            this.$message({
              message: "提示訊息",
              type: "success",
            });
 

default-expanded-keys

指定展開節點的key，及node-key

我的category.vue原始碼

<template>
  <div>
    <el-tree
      :data="menus"
      :props="defaultProps"
      show-checkbox=""
      node-key="catId"
      :expand-on-click-node="false"
      :default-expanded-keys="expandedkey"
    >
      <
 
span class="custom-tree-node" slot-scope="{ node, data }">
        <span>{{ node.label }}</span>
        <span>
          <el-button
            v-if="node.level <= 2"
            type="text"
            size="mini"
            @click="() => append(data)"
          >
            Append
          </el-button>
          <el-button
            v-if="node.childNodes.length == 0"
            type="text"
            size="mini"
            @click="() => remove(node, data)"
          >
            Delete
