I won’t say much nonsense, I will just post the code to you. The specific code is as follows:
<!-- Quickly implement quantity addition and subtraction -->
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<script src="/jquery/1.10.2/"></script>
<script>
$(document).ready(function(){
//Get text box objectvar t = $("#text_box");
//The initialization number is 1 and the failure is reduced$('#min').attr('disabled',true);
//Add number operation $("#add").click(function(){
// Add an absolute value to the obtained val to avoid negative numbers ((parseInt(()))+1);
if (parseInt(())!=1){
$('#min').attr('disabled',false);
};
})
//Number reduction operation $("#min").click(function(){
((parseInt(()))-1);
if (parseInt(())==1){
$('#min').attr('disabled',true);
};
})
});
</script>
</head>
<body>
<input name="" type="button" value="-" />
<input name="" type="text" value="1" style="width:30px;text-align: center"/>
<input name="" type="button" value="+" />
</body>
</html>
It is that simple to implement quantity addition and subtraction!
