新建全局代码片段==》输入自定义文件名称

第一步：文件==》首选项==》配置用户代码片段==》新建全局代码片段==》输入自定义文件名称

第一步：设置(鼠标左键)==》用户代码片段==》新建全局代码片段==》输入自定义文件名称

第二步：选择“新建全局代码片段文件，然后输入文件名称

第三步：自定义代码片段

----------------------------------自定义代码片段重点说明信息如下所示：----------------------------------

"Print to console：代码片段的名称，不同代码片段需要不同，在快捷输入中可以看到

scope：表示这个代码片段使用的语言，多种用,分隔，如果不写表示全部适用

prefix：表示快捷输入的字符串，输入的内容出现提示

body：生成代码的主体，具体在后续讲解

description：描述

{
// Place your 全局 snippets here. Each snippet is defined under a snippet name and has a scope, prefix, body and
// description. Add comma separated ids of the languages where the snippet is applicable in the scope field. If scope
// is left empty or omitted, the snippet gets applied to all languages. The prefix is what is
// used to trigger the snippet and the body will be expanded and inserted. Possible variables are:
// $1, $2 for tab stops, $0 for the final cursor position, and ${1:label}, ${2:another} for placeholders.
// Placeholders with the same ids are connected.
// Example:
// "Print to console": {
// "scope": "javascript,typescript",
// "prefix": "log",
// "body": [
// "console.log('$1');",
// "$2"
// ],
// "description": "Log output to console"
// }

// 自定义 script 动态生成代码片段

"myscript": {
//  "scope": "javascript,typescript,vue", //注释表示所有文件中可用
 "prefix": "myscript",
 "body": [
  "<script type=\"text/javascript\">",

  "",
  "</script>",
 ],
 "description": "自定义script"

},

 "myVue": {
//  "scope": "javascript,typescript,vue", //注释表示所有文件中可用
 "prefix": "myVue",
 "body": [
        "//console.log(vm)"
  "const vm = new Vue({",
  "el: '#root',",
        "data: {",
                "",
        "},"
        "",
        "methods: {"
            "methodOne() {",
                "alert('事件触发成功！')"
            "},"
            "",
            "methodTwo(event, str) {",
                "alert('事件触发成功！' + str)"
            "},"
            "},"
  "})",
 ],
 "description": "自定义script"

}
}
效果如下所示：
