How to limit number of button clicks per day in Javascript?-CodePudding

I want to limit the number of clicks on a button per day to 5 clicks using cookies. So when a user clicks 5 times, the button will no longer be clickable. I managed to do that, but the problem is when I refresh the page, the button is clickable again. So how to apply cookies to remember the user clicks?

My code:

<input type="text"  id="prompt" placeholder="Type anything">
<button id="the-button" type="submit">Send</button>
<script
  src="https://code.jquery.com/jquery-3.6.0.min.js"
  integrity="sha256-/xUj 3OJU5yExlq6GSYGSHk7tPXikynS7ogEvDej/m4="
  crossorigin="anonymous">
</script>   
<script type="text/javascript">                                         
localStorage.setItem("limit_click",5);
localStorage.setItem("count",1);
$("#the-button").on("click",function(){
    var limit = localStorage.getItem("limit_click");
    let count = parseInt(localStorage.getItem("count"));    
    if(count>=limit){
        alert('Your free limit counts has expired, please try again tomorrow or consider extending your plan.');
    }
    else{
        localStorage.setItem("count",parseInt(count) 1);
    }
}); 
</script>

I blocked the button when clicked 5 times. But, when page is refreshed, the button is clickable again.

What I want to do: Block the button after 5 clicks, and then even when the page is refreshed, the button is still blocked.

CodePudding user response：

Your code fails to check the localStorage before setting it to 1. Every page load you do localStorage.setItem("count",1);. This resets the count to 1, so every page load the localStorage is refreshed. This doesn't make sense, so do:

if(!localStorage.getItem("count")){
    localStorage.setItem("count",1);
}
