IF Greater无法在JS中正常运行 [英] IF Greater not working well in js

问题描述

我有2个数字输入字段，当用户停止输入时，以下内容将运行.我正在做的是检查输入的数字是否大于输入b的数字，以及是否显示错误.

I have 2 numeric input fields and the below runs when the user stops inputting. What I am doing is checking that input a number is not bigger than input b and if it is show error.

问题是计算进行得不好.例如，如果a为200且b为100，则有效，但如果a为200且b为5，则无效.

The issue is that calculation is not happening well. For instance it works if a is 200 and b is 100 but not if a is 200 and b is 5

不确定为什么...，所以将不胜感激.

Not sure why... so any help would be greatly appreciated.

$("#input_6_23, #input_6_24").on({  
  blur: function() {
        var a = document.getElementById("input_6_23").value;
        var b = document.getElementById("input_6_24").value;

        if(a > b) {     
            alert(a is bigger than b);          
        }
  }
});

推荐答案

工作正常吗?

 jQuery(document).ready(function($){

    $("#input_6_23, #input_6_24").on('blur',function() {

      check();
    });
    function check(){
       var a = Number($("#input_6_23").val());
       var b = Number($("#input_6_24").val());

       if(a > b) {     
        alert(a+' is bigger than '+b);          
       } else {
        alert("error");
    }  
}});
