    Making Array from html form

    If I have form like this:
    Code:
    <input type="text" name=" i[0]"/>
    <input type="text" name=" h[0] "/>
    <input type="text" name=" i[1] "/>
    <input type="text" name=" h[1] "/>
    How to make two Arrays one: i[] and the second: h[], after clicking submit, but without reloading page?

    you need to specify whether you are submitting the form data to html file or a server side script.

    post all your form code and not just bits and pieces

    I don't want to send it enywhere. I just want to show good answers to user.

    Look at it:
    Code:
    <script type="text/javascript"> 
    function error(blad) {
        if (errfound) return;
    	 for(i=0;i < blad.length;i++ ){
    	 
            document.getElementById("aa" + i).innerHTML = blad[i];}	
    		  			
    errfound = true;
    }
    function validate() {
        errfound = false;
    	 var blad = new Array();
    	  with (document.forms[0]) {
    	
    	 
    	 
    	 for(j=0;j < 3;j++ ){
            if (no[j].value == "good ansver") { blad[j] += "good";}
    		  else if(no[j].value == "") {blad[j] += "no ansver";}	
    		   else {blad[j] += "wrong ansver"; }		
            }
      
    	 
            if (blad != "" )  error(blad);
        }
    return !errfound;
    }
    </script>
    
    
    
    
    	<form action="#" method="post" onsubmit="return validate();">
    	
    		<p>1) Adrian ma na imię: </p>
    		<input type="text" name="no[0]"/><br/>
    		<span id="aa0"></span><br/>
    <p>2)What is the Adrian's name? </p>
    		<input type="text" name="no[1]"/><br/>
    		<span id="aa1"></span><br/>
    <p>3) Wie Adrian haisst du? </p>
    		<input type="text" name="no[2]"/><br/>
    		<span id="aa2"></span><br/>
      
    		<input type="submit" value="wyślij" />
    	</form>

    Ok, in that case you don't really need a <form> element, but it's ok to leave the <form>

    This quick and simple demo code shows how you can store input data into 2 arrays called inp1 and inp2 and display their values when you click the "Validate" button.

    Once you have the 2 arrays, you can do what you like with the values in them.

    Code:
     
    <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
     "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
    <html xmlns="http://www.w3.org/1999/xhtml">
    <head>
    <title></title>
    <script type="text/javascript">
    <!--
    
    function validate() {
          var inp1 = document.getElementsByName('i');
           var inp2 = document.getElementsByName('h');
           //display the input data
        var str = '';
        for(var i=0; i < inp1.length; i=i+1) {
         str += 'Input 1.'+(i+1)+' = '+inp1[i].value+"\nInput 2."+(i+1)+' = '+inp2[i].value+"\n";
        }    
     
     alert(str);
    
    }
    
    //-->
    </script>
    
    </head>
    <body>
    
    <div>
     
        Input 1.1 <input type="text" name="i"/><br />
         Input 1.2 <input type="text" name="i"/><br />
         Input 2.1 <input type="text" name="h"/><br />
         Input 2.2 <input type="text" name="h"/><br />
     
         <input type="button" value="validate" onclick="validate();" />
    <div>
     
    </body>
    </html>

    Ok it works, here I can name two of text inputs the same name, and it makes Array, but there is problem with radios. If I have:
    Code:
    <input type="radio" name="i[0]"/><br />
             <input type="radio" name="i[0]"/><br />
             <input type="radio" name="i[1]"/><br />
             <input type="radio" name="i[1]"/><br />
    And I have to have it in one, two dimensions Array, but I can't name two radios the same way.
