javascript - jQuery's click() inside "for" loop firing once -


this html code:

<!doctype html> <head>     <title>chemist</title>     <link href="stylesheet.css" rel="stylesheet"> </head> <body>     <h2 id="money"></h2>     <table border="1px" id="inventory_t"></table>     <script src="jquery.js"></script>     <script src="app.js"></script> </body> </html>

this app.js code:

var money = 10; var inventorynames = ["carbon", "hydrogen"]; var inventoryamounts = [5, 5]; var inventorylength = 2;  updatemoney(); populateinventory(); checkaddtomixclick();  function updatemoney(){     $("#money").text(money + "$"); } function populateinventory(){     $("#inventory_t").empty();     $("#inventory_t").append("<tr><td colspan='3'>inventory</td></tr>")     for(let = 0; < inventorylength; i++){         $("#inventory_t").append("<tr><td style='text-align:center'>" + inventorynames[i] + "</td><td style='text-align:center'>" + inventoryamounts[i] + "</td><td id='add_to_mix_" + + "'>+</td></tr>")     } } function checkaddtomixclick(){     for(let = 0; < inventorylength; i++){         $("#add_to_mix_" + i).click(function(){             inventoryamounts[i]--;             populateinventory();         });     } }

my problem when run , click "+" click() event fires, after nothing happens.

debugging shows when call checkaddtomixclick() function , click "+" works again, stops working after that.

any solution this?

just add checkaddtomixclick(); populateinventory() function, , remove checkaddtomixclick() top of code.

var money = 10;  var inventorynames = ["carbon", "hydrogen"];  var inventoryamounts = [5, 5];  var inventorylength = 2;    updatemoney();  populateinventory();    function updatemoney(){      $("#money").text(money + "$");  }  function populateinventory(){      $("#inventory_t").empty();      $("#inventory_t").append("<tr><td colspan='3'>inventory</td></tr>")      for(let = 0; < inventorylength; i++){          $("#inventory_t").append("<tr><td style='text-align:center'>" + inventorynames[i] + "</td><td style='text-align:center'>" + inventoryamounts[i] + "</td><td id='add_to_mix_" + + "'>+</td></tr>")      }      checkaddtomixclick();  }  function checkaddtomixclick(){      for(let = 0; < inventorylength; i++){          $("#add_to_mix_" + i).click(function(){              inventoryamounts[i]--;              populateinventory();          });      }  }
<!doctype html>  <head>      <title>chemist</title>      <link href="stylesheet.css" rel="stylesheet">  </head>  <body>      <h2 id="money"></h2>      <table border="1px" id="inventory_t"></table>      <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.1.0/jquery.js"></script>  </body>  </html>
