How many characters allowed in an alert box in JavaScript

Question

Does anyone know what is the maximum number of characters you can display in an alert box?

I\'m returning an error alert to the user with details for each of the erro

Answer 1

I don't know about limits in alert(), but I'm pretty sure that your code will produce an JS-syntax error.

Especially keep in mind that you cannot simply use strings in multiple lines in javascript. Please show us the output of your PHP-script.

Examples:

//will not work
alert('this
       is
       an 
       alert');

//This will work:
alert('this '+
       'is '+
       'an '+
       'alert');

//this works too:
alert('this \
       is \
       an \
       alert');
