This appears to be a browser issue with respect to the javascript alert() function. While the javascript spec does not place a limit on the amount of text you can put into alert(), web browsers have imposed limits on how much of the alert text will be displayed before it truncates the remaining text. It looks like you're using Google Chrome and you can verify that the limit is 1920 characters using the following script:

var alertText = "";
var i;
for(i=0; i<1920; i++) {
  alertText += "a";
}
alert(alertText);

This script will write a 1920 character string consisting only of the letter "a". When you trigger this in Chrome, you should see your alert pop up with no ellipsis. Now, change 1920 to 1921 in the for loop, and when you trigger the updated alert, you should see an ellipsis at the end of the alert. Firefox appears to cut off alerts at 10,000 characters (again, can be verified by changing the 1920 in the above script).

If you need to display this information as a pop-up instead of somewhere else in the page, you may need to pop up a modal or something like that instead of using alert().
