Solution to the Problem of Invalid Time Setting in JS

When sending the SMS verification code, the js time countdown problem needs to be solved: Sometimes this conventional writing method may cause js to fail, and many methods have been tried to find the problem, which may be due to the js version being too low.

setTimeout(showT(t-1),5000)

Solution:

setTimeout(function(){showT(t-1),1000)

or:

setTimeout("Talert(i)",5000);

jQuery code: It is necessary to use input to set the value in order to take advantage of jQuery to change the value

<<input type="button" id="sjyzm-btn" class="sjyzm-btn" value="Get Verification Code"/>

 var t = 120;
 　　showT(t);
  function showT(t) {
    if(t > 0){
     $(".sjyzm-btn").val(t +"seconds");
     setTimeout(function(){showT(t-1),1000)
     //setTimeout(showT(t-1),5000)
     //$('.sjyzm-$("btn").attr("disabled",true);
     }
     $(".sjyzm-btn").val("SMS Verification");
     //$(".sjyzm-$("btn").removeAttr("disabled");
    }
   }
