jQuery selects all selected values in the checkbox and submits data asynchronously using Ajax

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:

<body><p>    
<input type="checkbox" name="check"  value="1"/>复选框1
<input type="checkbox" name="check"  value="2"/>复选框2 
<input type="checkbox" name="check"  value="3"/>复选框3  <br/>     
<input type="checkbox" name="check"  value="4"/>复选框4 
<input type="checkbox" name="check" value="5"/>复选框5 
<input type="checkbox" name="check"  value="6"/>复选框6
<br/>
<input type="checkbox" name="check"  value="7"/>复选框7
<input type="checkbox" name="check"  value="8"/>复选框8
<input type="checkbox" name="check"  value="9"/>复选框9
<input type="button" id="dosubmit" value="提交">
</p>
</body>

Then start writing the jQuery program. The code is as follows:

 <script> 
$(&#39;#dosubmit&#39;).click(function(){ 
var checkID = {};//定义一个空数组 
 $("input[name=&#39;check&#39;]:checked").each(function(i){//把所有被选中的复选框的值存入数组
checkID[i] =$(this).val(); 
});
 //用Ajax传递参数
$.post(&#39;Ajax.php&#39;,{checkID:checkID},function(json){
 },&#39;json&#39;)
 })
 </script>

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 you have implemented the use of jQuery combined with Ajax batch operation check boxes to submit data. Here is just a simple demonstration of how to use jQuery combined with Ajax. The interface and code will be simpler.
