if(this.mode.dev_模式){ s=“background:222;color:bada55”; 案例‘I’: 休息; 休息; 休息; s=“background:green;color:white;'font-weight:bold;'”; 违约: }


   

问题




export const _log = function(msg, style, data?) {
    if(this.mode.dev_mode){
        data = (data) ? data : '';
        let s = "";
        switch ( style ) {
            case 't':
                s = "background: #222; color: #bada55";
                break;
            case 'i':
                s = "background: #efefef; color: blue; 'font-weight:900;'";
                break;
            case 'e':
                s = "background: red; color: white; 'font-weight:bold;'";
                break;
            case 'd':
                s = "background: #333; color: white; 'font-weight:bold;'";
                break;
            case 'y':
                s = "background: #FFBB3B; color: white; 'font-weight:bold;'";
                break;
            case 's':
                s = "background: green; color: white; 'font-weight:bold;'";
                break;
            default:
               s = "background: #222; color: #bada55";
        }
        console.log(`%c ${msg}`, s, data);
    }
};




_log(' == products ==> ', 'i', products);








看看所有日志都说什么是不使用原始函数的简单方法?例如,在这种情况下example.component.ts_global.ts……我可以每次都把它打印出来,但我更喜欢更自动化的东西,允许我保持Log()的简短。

_log(' == products ==> ', 'i', (new Error()), products);

export const _log = function(msg, style, error, data) {
    let infoLine = error.stack.split('\n')[1];
    // very ugly but I found it consistent
    let startingIndex = infoLine.indexOf('(') + 1;
    let endingIndex = infoLine.indexOf(')');
    let fileNameAndLine = (infoLine.substring(startingIndex, endingIndex))

    ...

    console.log(`%c ${msg} at ${fileNameAndLine}`, s, data);
}

How can I determine the current line number in JavaScript?
