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
1 [
2 {
3 "keys": [
4 "super+e"
5 ],
6 "args": {
7 "action": "expand_abbreviation"
8 },
9 "command": "run_emmet_action",
10 "context": [
11 {
12 "key": "emmet_action_enabled.expand_abbreviation"
13 }
14 ]
15 },
16 {
17 "keys": [
18 "tab"
19 ],
20 "command": "expand_abbreviation_by_tab",
21 "context": [
22 {
23 "operand": "source.js",
24 "operator": "equal",
25 "match_all": true,
26 "key": "selector"
27 },
28 {
29 "key": "preceding_text",
30 "operator": "regex_contains",
31 "operand": "(\b(a\b|div|span|p\b|button)(\.\w*|>\w*)?([^}]*?}$)?)",
32 "match_all": true
33 },
34 {
35 "key": "selection_empty",
36 "operator": "equal",
37 "operand": true,
38 "match_all": true
39 }
40 ]
41 }
42 ]
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
1 [{
2 "keys": ["tab"],
3 "command": "expand_abbreviation_by_tab",
4
5 // put comma-separated syntax selectors for which
6 // you want to expandEmmet abbreviations into "operand" key
7 // instead of SCOPE_SELECTOR.
8 // Examples: source.js, text.html - source
9 "context": [{
10 "operand": "source.js",
11 "operator": "equal",
12 "match_all": true,
13 "key": "selector"
14 },
15
16 // run only if there's no selected text
17 {
18 "match_all": true,
19 "key": "selection_empty"
20 },
21
22 // don't work if there are active tabstops
23 {
24 "operator": "equal",
25 "operand": false,
26 "match_all": true,
27 "key": "has_next_field"
28 },
29
30 // don't work if completion popup is visible and you
31 // want to insert completion with Tab. If you want to
32 // expand Emmet with Tab even if popup is visible --
33 // remove this section
34 {
35 "operand": false,
36 "operator": "equal",
37 "match_all": true,
38 "key": "auto_complete_visible"
39 }, {
40 "match_all": true,
41 "key": "is_abbreviation"
42 }
43 ]
44 }]
