jquery implements dynamic operation select_jquery

Today, because I have a project that requires dynamic operation of select selection habits, I searched it on Baidu, and there were quite a lot of results. I tried one of them and found that it could not be used. I opened the second and third ones and found that they were all the same, and then I did some research on my own. Just a moment

Copy code The code is as follows:

//Initialize select, the first one is selected
                 $('#stoStoreCategoryID').get(0).selectedIndex=0;
                $("#stoStoreCategoryID option").each(function(i,n){
If($(n).text()==data.scName)
                                                {
$(n).attr("selected",true);
                }
             })

I just need to judge whether the text is the same. If I want to judge whether the values ​​are the same

Copy code The code is as follows:

if($(n).val()==data.scName)

That’s it. I saw this code on the Internet

Copy code The code is as follows:

//Set the item with text as pxx selected
$(".selector").find("option[text='pxx']").attr("selected",true);

It feels feasible, but the operation was not successful

What I wrote is relatively simple. I wasn’t planning to post it at first, but I spent a lot of time on it. I sent it to others and also kept it for myself.
