Parsing reponseText from C++ to Javascript

calorie712 · 04-27-2007, 11:40 PM

I can't parse my output from a .cpp file. can someone help me with the responseText and how I am using response[?].

Code:

function getServerHealth()
{
	var req = null;
	var url;
	var response;
	var info = new Array();
	var response;
	var i;
	if (window.XMLHttpRequest)
		req = new XMLHttpRequest();
	else if (window.ActiveXObject)
		req = new ActiveXObject(Microsoft.XMLHTTP);

	url = "serverHealth.cgi";

	req.open("GET", url, true);

	req.onreadystatechange = function()
	                         {
		                         if(req.readyState == 4)
		                         {
			                         if(req.status == 200)
			                         {
				                         response = req.responseText.split(" , ");
				                         document.getElementById("topOutput").innerHTML= response[0];


				                         for(i = 2 ; i < response.length; i++)
				                         {
					                 
					                        document.getElementById("bottomOutput").innerHTML =+ response[i];
				                         }

			                         }
		                         }
		                         //else
		                         //{
			                   //      document.getElementById('bottomOutput').value =
			                   //          "Error: returned status code " + req.status + " " + req.statusText;
		                         //}
	                         }

	                         req.send(null);
	//Recursive JavaScript function calls getDateTime() every second
	setTimeout("getServerHealth()", 5000);
}

Code:

/* The "intelligence" for the serverHealth program. */
#include <string>
#include <iostream>

using namespace std;

#include <stdio.h>
#include <unistd.h>


int main() {
  FILE *read_fp, *read_fp2;
  char buffer[BUFSIZ + 1];
  string mybuffer, str;
  int chars_read;
   
  cout << "Content-Type: text/html\n\n" << endl; 

  memset(buffer, '\0', sizeof(buffer));

  read_fp = popen("uptime", "r");
  if (read_fp != NULL) {
    chars_read = fread(buffer, sizeof(char), BUFSIZ, read_fp);
    if (chars_read > 0) {
      mybuffer.assign(buffer);
	  mybuffer.append(" , ");
	  cout << mybuffer << endl;
    }
    pclose(read_fp);
  }
  
read_fp2 = popen("tail -5 /var/www/logs/error_log", "r");
  if (read_fp2 != NULL) {
    chars_read = fread(buffer, sizeof(char), BUFSIZ, read_fp2);
    if (chars_read > 0) {
      str.assign(buffer);
	  cout << str << endl;
    }
    pclose(read_fp2);
  }
   return 0;
}
