Question

window.onerror = function(type, file, line){
        if(type) {
            console.log(type);
        }
        if(file) {
            console.log(file);
        }
        if(line) {
            console.log(line);
        }
    }

this code returns "Script error" when there is an error at some of the .js files. I need the type, file and line of the error. How can I get it? When window throws error this script works perfect but it is not the same when there is error in the .js file. I know that these things I can find on the console but imagine that I don t have one and i cannot install.

Answer 1

window.onerror = ErrorLog;
function ErrorLog (msg, url, line) {
    console.log("error: " + msg + "
" + "file: " + url + "
" + "line: " + line);
    return true; // avoid to display an error message in the browser
}

Cryptic“Error”在Javascript in Ü and 上报,应回答“Error 问题”。也就是说,这可能是由“同源政策”造成的。

尽管我仍在研究为什么要给我“不明确的”档案名称和“0”线号,以备无选择。

这里我用来描述错误。我要求有一个图像,该图像的斜向服务器的侧面书写。

function logJSErrors(errObj) {
  if (!errObj || !errObj.lineNumber || errObj.lineNumber == 0) {
    return; // can t use it any way.
  }
  if (window.location && window.location.toString().indexOf( rfhelper32.js ) >= 0) {
    return; // ignore the stupid Norton/Firefox conflict
  }

  var img = new Image();
  img.src = "/jserror?m=" + encodeURIComponent(errObj.message) +
      "&location=" + encodeURIComponent(window.location) +
      "&ln=" + encodeURIComponent(errObj.lineNumber) +
      "&url=" + encodeURIComponent(errObj.fileName) +
      "&browser=" + encodeURIComponent(errObj.browserInfo);
}

window.onerror = function (msg, url, line) {
  logJSErrors({ message : msg,
    lineNumber : line,
    fileName : url,
    browserInfo : window.navigator.userAgent
  });

  // if a jquery ajax call was running, be sure to make the spinning icons go away
  if (jQuery) {
    try {
      jQuery.event.trigger("ajaxStop");
    } catch(e) {/* do nothing */
    }
  }

};
