//根据DOM元素的id构造出一个编辑器
var editor=CodeMirror.fromTextArea(document.getElementById("code"),{
    mode:"text/c-mysql", //实现Java代码高亮
    lineNumbers:true,
    matchBrackets: true, //括号高亮匹配
    theme:"default",
    keyMap: "default",
    extraKeys:{"Tab":"autocomplete"},
    hint: CodeMirror.hint.sql,
    lineWrapping: true,         //是否换行
    foldGutter: true,           //是否折叠
    gutters: ["CodeMirror-linenumbers", "CodeMirror-foldgutter"], //添加行号栏，折叠栏
    hintOptions: {
        tables: tablewords

    }

});
