for循环正常工作与console.log但不是innerHTML？ [英] for loop works fine with console.log but not innerHTML?

问题描述

你好，我是非常新的JavaScript，所以原谅我，如果答案似乎明显...

这是我的代码是在点击一个按钮在体内

 函数q（）{
 
 var A = document.getElementById（time_one ）。值; 
 var B = document.getElementById（time_two）。value; 
 var C = document.getElementById（post_number）。value; 
 
 var D =（B  -  A）/ C; （var x = A; x  
 document.getElementById（q_box）。innerHTML = x +< b 
 $ b< ; / / 
 
 
 
 
 
 
 $ b 
我很确定错误在for循环中...输出应该是A和B之间的数字列表，并且将innerHTML =更改为innerHTML + =也没有工作吗？
解决方案
 
  function q（）{
 
 var A = + document.getElementById （ time_one）值; 
 var B = + document.getElementById（time_two）。value; 
 var C = + document.getElementById（post_number）。value; 
 
 var D =（B  -  A）/ C; （var x = A; x  
 document.getElementById（q_box）。innerHTML + = x +b 
 $ b < br />; 
 
 
 
 
 
 $ b 
你应该转换 int 中的值，您应该使用 + =  
 
hello i'm very new to javascript so forgive me if the answer seems obvious...

this is my code which is executed at the click of a button in the body
function q() { 

    var A = document.getElementById("time_one").value;
    var B = document.getElementById("time_two").value;
    var C = document.getElementById("post_number").value;

    var D = (B - A) / C;

    for ( var x = A; x < B; x = x + D ) {

    document.getElementById("q_box").innerHTML = x + "<br />";

    }


}
i'm pretty sure the error is in the for loop... the output is supposed to be a list of numbers between A and B. and changing the innerHTML = to innerHTML += hasn't worked either?
解决方案
function q() { 

    var A = +document.getElementById("time_one").value;
    var B = +document.getElementById("time_two").value;
    var C = +document.getElementById("post_number").value;

    var D = (B - A) / C;

    for ( var x = A; x < B; x = x + D ) {

    document.getElementById("q_box").innerHTML += x + "<br />";

    }

}
You should convert the values in int and you should use +=
