I recently encountered a small problem, that is, sometimes when we use single-select radio, we will find that after we select one, we can no longer select none, that is, there is no cancel function after selecting. Then I thought of the powerful checkbox, but it has multiple selections. How can I turn it into a single selection? The effect is the same as radio. I wrote a small program myself. The code is very simple, only four lines.
No more nonsense, direct code:

$(function(){ 
$(":checkbox").click(function(){ 
if($(this).attr("checked")!=undefined) 
{ 
$(this).siblings().attr("checked",false); 
$(this).attr("checked",true); 
} 
}); 
}); 
</script> 
<style> 
span,input{float:left;} 
input{ width:14px; height:14px;} 
span{ margin-right:20px;} 
</style> 
</head>

<input type="checkbox" /><span>1</span>
