前端异常日志记录

// 基于window.onerror 收集前端错误信息
window.onerror = function (message, url, line) {
    if (!url) return;

    var msg = {
        ua: window.navigator.userAgent,
        message: message,
        url: url,
        line: line,
        page: window.location.href
    };

    new Image().src = ‘/Home/UiErrorLog?error=‘ + encodeURIComponent(JSON.stringify(msg)) + ‘&t=‘ + Math.random();
};
