Question

有谁知道从 Codemirror 的自动完成中删除一些全局变量的有效方法吗？

例如 StyleFix、PrefixFree、Html2Jade 等:不应可见。

以下是其摘要:(来自 https://codemirror.net/doc/manual.html#addon_javascript-hint )

This will simply use the JavaScript environment that the editor runs in as a source of information about objects and their properties.

及相关源码:

var found = [], start = token.string, global = options && options.globalScope || window;

和

function gatherCompletions(obj) {
  if (typeof obj == "string") forEach(stringProps, maybeAdd);
  else if (obj instanceof Array) forEach(arrayProps, maybeAdd);
  else if (obj instanceof Function) forEach(funcProps, maybeAdd);
  for (var name in obj) maybeAdd(name);//important
}

(来自 https://mikethedj4.github.io/kodeWeave/editor/libraries/codemirror/addon/hint/javascript-hint.js )

其中obj是全局。

因此，如果您想删除一些全局变量 ，只需修改 globalScope 参数即可。

更改此行:

CodeMirror.commands.autocomplete(cm,null, {completeSingle: false});

至

var scope={};
var preventList=['StyleFix', 'PrefixFree', 'Html2Jade','alert'];// map is better
for(var i in window){
  if(preventList.indexOf(i)===-1){
    scope[i]=window[i]
  }
}
CodeMirror.commands.autocomplete(cm,null, {completeSingle: false,globalScope:scope});
