Javascript 使用技巧(一)

//将逗号和"|" 替换为"and" 和 "or"

var text='A,B,C|D,E,F|G|K';
(function parseSigningRule(text){
    if(isEmpty(text))
        return text;
    var output = '';
    var array = text.split(",");
    var signatureCount = array.length;
    $.each(array, function(idx, val){
        var wrapNeeded = false;
        if(val.split("|").length > 1 ){
            wrapNeeded = true;
        }

        if(signatureCount == 1){
            wrapNeeded = false;
        }

        val = val.replace(/\|/g , " or ");

        if(wrapNeeded){
            val = '( '+val+' )';
        }
        if(idx > 0){
            output += ' and ';
        }
        output += val;
    });

    console.log(output);
    return output;
})(text);
