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": ["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"
        }
    ]
}]
