jQuery uses the selected value of the check box and Ajax to asynchronously submit data

Yesterday, when I was working on a backend management system project with my friends, it involved batch operations of check boxes. It was very convenient to submit using the submit form, but it was a bit troublesome to use jQuery combined with Ajax to submit data asynchronously, because I had done it before. Ajax is basically not used to submit check box data in batches in the projects I have worked on. I will share it today if I use it.
Since some parts of the project I am doing are relatively complicated, I will only give a small example here, as long as you can understand it.
First of all, I made a simple interface with multiple check boxes, as shown in the picture:
This is a relatively simple multiple check box interface Box submission interface. The code is as follows:
1 <body> 2 <p> 3 <input type="checkbox" name="check" value="1"/>复选框1 4 <input type="checkbox" name="check" value="2"/>复选框2 5 <input type="checkbox" name="check" value="3"/>复选框3 6 <br/> 7 <input type="checkbox" name="check" value="4"/>复选框4 8 <input type="checkbox" name="check" value="5"/>复选框5 9 <input type="checkbox" name="check" value="6"/>复选框6 10 <br/> 11 <input type="checkbox" name="check" value="7"/>复选框7 12 <input type="checkbox" name="check" value="8"/>复选框8 13 <input type="checkbox" name="check" value="9"/>复选框9 14 <input type="button" id="dosubmit" value="提交"> 15 </p> 16 </body>
Then I started writing the jQuery program. The code is as follows:
1 3f1c4e4b6b16bbbd69b2ee476dc4f83a
2 $('#dosubmit').click(function(){
3 var checkID = [];//定义一个空数组
4
5 $("input[name='check']:checked").each(function(i){//把所有被选中的复选框的值存入数组
6 checkID[i] =$(this).val();
7 });
8
9 //用Ajax传递参数
10 $.post('Ajax.php',{checkID:checkID},function(json){
11
12 },'json')
13 })

Note: You must introduce the JQ library file before writing jQuery, otherwise it will be useless no matter what you do, don’t be careless, I am like this sometimes... .....
Okay, all the preparations are done, let’s start testing:
I checked a few boxes first:
After clicking the "Submit" button, open F12 debugging, and the result is as shown in the figure:
OK, now the batch operation check box using jQuery combined with Ajax has been implemented Data submitted. Here is just a simple demonstration of how to use jQuery combined with Ajax. The interface and code will be simpler.
