Question

我试图在变量t = <100时显示一些文字，但它不起作用，我不明白为什么：（

var t = 100;
function tel(){	
	t--;
	console.log(t);
return document.getElementById("lol").innerHTML = t;
}
if (t < 97){
	document.getElementById('nba').innerHTML = ('Ja he');
}else {
	document.getElementById('nba').innerHTML = ('Blijf klikken')
}
if (t < 35){
	document.write("op de helft");
}

<!DOCTYPE html>
<html>
<head>
<title>madafaka</title>
<link rel="stylesheet" href="style.css">

</head>
<body>
<div id="wrap">

<p id="tel"></p>
<br>
<button id="lol" type="button" onclick="tel()">Klik!</button>

<p id="nba"></p>
<script src="jav.js"></script>
</div>
</body>
</html>

好像没有打印文字，我不明白为什么。

Answer 1

您必须使用函数中的比较代码= tel（）;

＆＃13;

  protected void Page_Load(object sender, EventArgs e)
{
    ddlGM.Attributes.Add("OnClick", "dropdownload()");

          if (!IsPostBack)
          {  FillAccounts();
           }
  }

   protected void btnHidden_Click(object sender, EventArgs e)
  {
    DataView dvfilters = (DataView)(Cache["FiltersData"]);
    dtt = dvfilters.ToTable();
    ddlGM.DataSource = dtt;
    ddlGM.DataValueField = "GlobalMarket";

    ddlGM.DataBind();
    RemoveDuplicateItems(ddlGM);
    SortDDL(ref ddlGM);
    //ddlGM.Items.Insert(0, "All");
}

＆＃13;

var t = 100; 
function tel(){    
  t--;
  console.log(t);
  
  // compares
  if (t < 97){
    document.getElementById('nba').innerHTML = ('Ja he');
  }
  else {
   document.getElementById('nba').innerHTML = ('Blijf klikken')
  }
  if (t < 35){
    document.write("op de helft");
  }

  return document.getElementById("lol").innerHTML = t;
}

＆＃13;

.as-console-wrapper { max-height: 10% !important; }

＆＃13;

Answer 2

您在if(){} else{}之外验证您的代码，并在检查完成之前返回新值。请记住，您的浏览器从上到下阅读。当计数器低于35时，您的按钮将被替换为“op de helft”。
