Question

当我点击输入你的名字时，div标签中不会弹出任何内容。我的目标是尝试使名称出现在具有不同id的所有span标签中。但它甚至不会出现在一个。我也在使用纯JavaScript

<!DOCTYPE html>
<html>
<head>
    <meta charset="utf-8">
    <link rel="stylesheet" type="text/css" href="DreStone.css">
 <title> o </title>
<style> 

</style>

       <!-- JAVASCRIPT -->
    <script src="util.js"></script>

<script> 
/**********************
LOCAL NAMESPACE OBJECT
***********************/
var z={};


/**********************
EVENT HANDLERS
***********************/
z.showName = function()
  { var age = u.eid("names").value,
  u.eid("firstname").innerHTML = "" + age;

}  

/**********************
WINDOW.ONLOAD
***********************/
window.onload = function()
{ 
u.eid("nameinput").addEventListener('click', z.showName);
} 

</script> 

</head> 

<body> 

Please enter your name: <input id="names" type="text"> 

<button id="nameinput" type="button">Click after you enter your name</button>

<p> 
How is your day going <span id="firstnam"> </span>
  </p> 
<div>        I would like to you to take a look at this payment plan <span id="secondname"> </span>.
It may prove to be very valueable to you. If you do not care then ignore this.  Thank you <span id="thirdname"> </span> 
</div>
<div id="firstname">
</div> 
</body>
</html>

任何帮助都会非常有用。感谢

Answer 1

如何将其更改为替换功能？类似的东西：

document.body.innerHTML = document.body.innerHTML.replace("How is your day going", "How is your day going " + document.form[0].user.value] + "?");

Answer 2

假设 u.eid（）在util.js中并且有效，你有（，）instaed of（;）

Answer 3

试试这个：

<!DOCTYPE html>
<html>
<head>
    <meta charset="utf-8">
 <title> o </title>
<style> 

</style>

<script> 
/**********************
LOCAL NAMESPACE OBJECT
***********************/
var z={};


/**********************
EVENT HANDLERS
***********************/
z.showName = function()
  { var age = document.getElementById("names").value;
  document.getElementById("firstname").innerHTML = "" + age;

}  

/**********************
WINDOW.ONLOAD
***********************/
window.onload = function()
{ 
document.getElementById("nameinput").addEventListener('click', z.showName);
} 


</script> 

</head> 

<body> 

Please enter your name: <input id="names" type="text"> 

<button id="nameinput" type="button">Click after you enter your name</button>

<p> 
How is your day going <span id="firstnam"> </span>
  </p> 
<div>        I would like to you to take a look at this payment plan <span id="secondname"> </span>.
It may prove to be very valueable to you. If you do not care then ignore this.  Thank you <span id="thirdname"> </span> 
</div>
<div id="firstname">
</div> 
</body>
</html>
