Solving problems caused by different Jquery versions_javascript skills

This is the most perfect work written in the past three months. It uses JS to implement a drag and drop sorting. The rendering is as follows:

When I first entered the project, I had such a drag and drop implementation. I have no idea at all. Please ask my teacher to tell me that this is impossible. I felt very sorry at the time and planned to use traditional methods to achieve it. I was thinking about the traditional way and felt I had plenty of time, so I came back to the idea of ​​dragging. It finally happened. In fact, I am not showing off this (of course, if you are interested, you can contact me at QQ907087894, I will organize the demo and upload it to the resource center), what I want to say is the following.
While I was implementing it, my senior sister helped another partner write a demo of a traditional solution, and he was sorting the modifications. When I demonstrated it on her machine, I felt very shocked at the time. With the slide of her mouse, I walked through the code and looked at the long chain of JS, and I suddenly admired it. At that time, I thought that after the project was completed, I would study her carefully.

2 months later, the wait is here, free time. Due to my unfamiliarity with JS, I struggled to understand the code. When I was running it, a bug flew in. When moving, it keeps saying there are no options.

Copy code The code is as follows:

for(var j = 0; j < div_count; j ){
if(($("#eva_div_all").children().eq(j).children().children().eq(0).attr('checked'))=='checked '){
var valid_checked = $("#eva_div_all").children().eq(j).children().children().eq(0).attr('id');
if (valid_checked==checked_name){alert(alert_des);return;}
                                                                                                                                                                                 ');
var temp_html = $("#" temp).html();
var before_temp = $("#eva_div_all").children().eq(j num).attr('id' );
var before_temp_html = $("#" before_temp).html();
$("#" temp).html(''); '');
$("#" temp).html(before_temp_html);
$("#" before_temp).html(temp_html);            new_order( ); ! ');
}


It was as if a flying insect had entered my eye. I kept rubbing it and rubbing it, but it couldn't come out. This was how I spent the day.
I had no choice but to untie the bell, so I needed someone to tie the bell. She came and debugged it for a long time, but it still didn’t work. Later, when I compared her local code, there was no difference, and her local code was running normally. Later we reached a consensus on the browser issue.




Copy code

The code is as follows:

$("#eva_div_all").children(). eq(j).children().children().eq(0).attr('checked'))=='checked')
Browsers have different support for the ehecked attribute.

She is firefox 23, mine is 16.0.1. I'm very happy that I finally found the crux of the problem and this matter is finally over.

A week later today, using the same browser to access resources on the server, this problem no longer exists. Let’s study it.
Fortunately, I don’t know where the inspiration came from. I replaced the originally introduced jquery.js with jquery-1.7.2.min.js, and the problem was finally solved again.
I don’t know if it will be overthrown again, haha~~
