sublime text 3 ，React，html元素自动补全方法（用Emmet写法写jsx中的html）

1. 安装emmet: Preferences -> Package Control -> Install Package -> emmet
2. 配置emmet： Preferences -> Package Settings -> Emmet -> Key Bindings - User
   将下方的代码贴到打开的文件中，然后就可以使用tab键对render中的（部分）html元素使用自动补全功能了

[
    {
        "keys": [
            "super+e"
        ],
        "args": {
            "action": "expand_abbreviation"
        },
        "command": "run_emmet_action",
        "context": [
            {
                "key": "emmet_action_enabled.expand_abbreviation"
            }
        ]
    },
    {
        "keys": [
            "tab"
        ],
        "command": "expand_abbreviation_by_tab",
        "context": [
            {
                "operand": "source.js",
                "operator": "equal",
                "match_all": true,
                "key": "selector"
            },
            {
                "key": "preceding_text",
                "operator": "regex_contains",
                "operand": "(\\b(a\\b|div|span|p\\b|button)(\\.\\w*|>\\w*)?([^}]*?}$)?)",
                "match_all": true
            },
            {
                "key": "selection_empty",
                "operator": "equal",
                "operand": true,
                "match_all": true
            }
        ]
    }
]

补充：

在贴了上述代码之后，只有部分标签用tab键能够自动补全，但是还有很多标签只能用ctrl+e补全，比如h1,Route等，经查阅，将上述代码替换为下面的代码，则能解决这个问题

[{
    "keys": ["tab"],
    "command": "expand_abbreviation_by_tab",

    // put comma-separated syntax selectors for which 
    // you want to expandEmmet abbreviations into "operand" key 
    // instead of SCOPE_SELECTOR.
    // Examples: source.js, text.html - source
    "context": [{
            "operand": "source.js",
            "operator": "equal",
            "match_all": true,
            "key": "selector"
        },

        // run only if there's no selected text
        {
            "match_all": true,
            "key": "selection_empty"
        },

        // don't work if there are active tabstops
        {
            "operator": "equal",
            "operand": false,
            "match_all": true,
            "key": "has_next_field"
        },

        // don't work if completion popup is visible and you
        // want to insert completion with Tab. If you want to
        // expand Emmet with Tab even if popup is visible -- 
        // remove this section
        {
            "operand": false,
            "operator": "equal",
            "match_all": true,
            "key": "auto_complete_visible"
        }, {
            "match_all": true,
            "key": "is_abbreviation"
        }
    ]
}]
