Javascript JS属性值onclick replace

我使用codemirror和jquery在浏览器中“模拟”xml编辑器。一些xml标记包含一个“on”属性，该属性有两个可能的值（true或false）。是否可以在onclick事件中切换这些值？codemirror/jquery插件可用吗

自编码解决方案

到目前为止还不是完美的（糟糕的设计等等），但它的工作原理与预期相符：

只需在onclick事件中触发该函数

function attributeToggle(){

    var transitions = {
        "on": {
            "false":"true",
            "true":"false"
        }
    }


    var pos = editor.getCursor(); // object {line, ch}
    var token = editor.getTokenAt(pos);
    var line = editor.getLine(pos.line);

    try{

        var prev_pos = token.start - 1;
        var prev_token = editor.getTokenAt({'line':pos.line, 'ch':prev_pos});

        if(prev_token.className == "attribute")
            var attr = prev_token.string;
        else
            return false;

        if(typeof transitions[attr] === "undefined") //nothing to replace
            return false;

        var current_val = token.string.toLowerCase().replace(/(['"])/g, "");


        if(typeof transitions[attr][current_val] === "undefined")
            return false;

        var line_new =  line.substring(0, token.start) + \
 "\"" + transitions[attr][current_val] + "\"" +  line.substring(token.end);

        editor.setLine(pos.line, line_new);


    } catch (e){
        console.log(e);
    }
}

只是想澄清一下：您正在CodeMirror中编辑XML，并且拥有类似于

的XML，当用户在文本编辑器中单击该节点时，您希望将其更改为

？是的！哪条路最好？

$(".CodeMirror").attr("onclick","javascript:attrtoggle()");

function attributeToggle(){

    var transitions = {
        "on": {
            "false":"true",
            "true":"false"
        }
    }


    var pos = editor.getCursor(); // object {line, ch}
    var token = editor.getTokenAt(pos);
    var line = editor.getLine(pos.line);

    try{

        var prev_pos = token.start - 1;
        var prev_token = editor.getTokenAt({'line':pos.line, 'ch':prev_pos});

        if(prev_token.className == "attribute")
            var attr = prev_token.string;
        else
            return false;

        if(typeof transitions[attr] === "undefined") //nothing to replace
            return false;

        var current_val = token.string.toLowerCase().replace(/(['"])/g, "");


        if(typeof transitions[attr][current_val] === "undefined")
            return false;

        var line_new =  line.substring(0, token.start) + \
 "\"" + transitions[attr][current_val] + "\"" +  line.substring(token.end);

        editor.setLine(pos.line, line_new);


    } catch (e){
        console.log(e);
    }
}
