JavaScript函数警告框在Firefox中不起作用

Question

I have the following code in my JavaScript that will show an alert box. The code works fine in Google Chrome and IE, but not in Firefox.

$(document).ready( function() {
                                jAlert('You have already selected <?php echo $int; ?> theme.
Please deselect one of the themes to choose a new theme.', 'Number Of Theme Exceeded');
                        });
                        return false; 

How can I go about changing it to allow it to work in Firefox?

Answer 1

From your question it is very difficult to get the error. As I don't know the code of your jAlert. But there may be many reasons behind that.

First: Check your jQuery version and browser compatibility.

Second: Your browser version (Old/New)

And from your code One thing seems to be correct. You return false; outside of your function. Which should be like that-

$(document).ready( function() {
    jAlert('You have already selected <?php echo $int; ?> theme.
Please deselect one of the themes to choose a new theme.', 'Number Of Theme Exceeded');
//return false;
/*
 return false should be inside of some function. 
 If you are copy this code from somewhere then comment this line.
*/                 
});
