JavaScript json prompt in IE6/IE7 is missing identifier, string or number problem handling_javascript skills

When I used Jquery Ui Datapicker to display the sign-in calendar function yesterday, a Js problem occurred. It displayed normally under IE8/IE9, FF, and Chrome.

However, there is a problem with the display in IE6/IE7 and IE8 compatible views, prompting "There is an error on the page". Further inspection shows the error message "Missing identifier, string or number",

At first I thought it was caused by the mismatch between Jquery and Jquery Ui versions. Later I tried other supported versions but it didn’t work either.

Then I debugged my Js code piece by piece. After spending more than two hours, I finally discovered that the problem was caused by a comma after the last key value of Json.

I checked online and found that many people also encountered this problem. Be careful in the future.

Copy code The code is as follows:

var obj = {
         'name': 'qqyumidi',
         'gender': 'male' //Cannot add, here! !
}
alert(obj.name);

It’s really evil IE6/IE7. When will we say goodbye to the days of doing hacks specifically for IE. . . . . I can’t help but complain about Microsoft
