I have an array question?

@wb31Apr 02.2009

I am know to Javascript so this is probably a basic question. How do I store user information from a field to an array and call it using a button to print it out later?

@JMRKERApr 02.2009 — #Need more information.

1. What kind of information? Number, string, logic? Any special formatting?

2. What kind of field? Textbox, Textarea, selectbox value, radio button value?

Too many unknowns to comment.

Post what you have up to the point of problems.

@wb31authorApr 02.2009 — #Ok, I am looking to use a text field where the user can enter their name. The kind of information is a string. When the add button is activated an alert box shows their name.

Here is my code

<html>

<head>

<script>

function submitForm()

{

var myForm = document.registrationForm;
 
  var user_name = name;
  var name = document.getElementById("enterName"); 
 
 
 
  var myUserName;
 
 
  var name = "";
  var userarray; 
 
 
 
  if (myUserName == "")
  { 
   var userarray = new Array();
   var myUserName = myForm.user_name.value; 
   myName = "<p style=color:red>Please enter your First name.</p>"; 
   myUserName = name;
   name.innerHTML = myName;
   //alert(myUserName);
   return false; 
  } 
  else 
  { 
   var userarray = new Array(1);
   userarray[0] = "";
   var myUserName = myForm.user_name.value; 
   myUserName = userarray; 
   alert(userarray[0] = "");
  }

}

</script>

</head>

<scprit>

<body>

<form>

<table bgcolor="silver">
   <thead>
   <tr>
   <th><h1>String Manipulation Assignment<h1></th>
   </tr>
 
   </thead>
  <tbody>
   <tr>
   <td><h2>Search/Add Students<h2></td>
   </tr>
   <tr> 
   <td>Name<input id="user_name" type="text" name='user_name'></td>
   <td><p align="left" id="enterName"></p></td>
   </tr>
 
   <tr>
   <td>
   <input name="btnAdd" type="submit" value="Add" onclick="submitForm();">
   <input name="btnReset" type="reset" value="Reset" onclick="btnReset();"></td>
 
   </tr>
   </tbody> 
   </table>

</form>

<p id="printName"></p>

</body>

</script>

</html>

@JMRKERApr 03.2009 — #You have a number of errors that will not allow the script to run. :eek:

If using FF, check the error console. ?

1. <script> tag needs further definition: <script type="text/javascript">

2. Mis-spelled <script> tags

3. Not correctly nested <script> tags, ie surrounding <body> ???

4. Form name is missing.

5. Add some alert('Messages') at different locations to see values assigned as you debug.

Use [ code] [ /code] tags (without spaces) around you scripts to make it easier to read.
