getElementById help

if i have the following line of code, could i somehow get the value of each textfield by assigning it to an array???

  function submitSave()
  {
     var iarray  = new Array();

     for (i=0; i<numItems; i++)
     {
         document.getElementById("textfields").value = iarray;         
     }
  }

Code (markup):

 

What this will do is it will convert the content of the array to a comma-delimited list of values (which will be empty in this case 'cause you just created an array) and assign it to the text field.

Simply put, this assignment will reset the content of "textfields" to a zero-length string.

J.D.

 

var iarray = "value1_value2_value3".split('_');

for (i=0; i<iarray.length; i++)
{
document.getElementById("textfields").value = iarray;
}

 

If you want to get the values from the FORM into the ARRAY, then you need something like:

for (i=0; i<numItems; i++)
{
iarray=document.getElementById("textfields" + i).value;
}

Something like this, anyway..

 

You have a div you want to write to. Make it : <div id="holder"></div>.Then -
document.getElementById("holder").innerHTML = blah

You cannot get info from submit into javascript. You must post, or alternately, get, with the submit call from your input text form (on submit="file.php" action="post/get").

Lets say you make a httprequest for "doc.xml", either in the 'onload' function, or with an evewnt caller:
function sendRequest(doc){
// check for existing requests
if(xmlobj!=null&&xmlobj.readyState!=0&&xmlobj.readyState!=4){
xmlobj.abort();
}
try{
// instantiate object for Mozilla, Nestcape, etc.
xmlobj=new XMLHttpRequest();
}
catch(e){
try{
// instantiate object for Internet Explorer
xmlobj=new ActiveXObject('Microsoft.XMLHTTP');
}
catch(e){
// Ajax is not supported by the browser
xmlobj=null;
return false;
}
}
// assign state handler
xmlobj.onreadystatechange=stateChecker;
// open socket connection
xmlobj.open('GET',doc.xml,true);
// send GET request
xmlobj.send(null);
}

Then, you check for a return:

function stateChecker(){
// if request is completed
if(xmlobj.readyState==4){
// if status == 200 display text file
if(xmlobj.status==200){
// create data container
createDataContainer();
// read XML data
data=xmlobj.responseXML.getElementsByTagName('message');
// display XML data
displayData();
}
else{
alert('Failed to get response :'+
xmlobj.statusText);
}
}
}

in which you have : <div id="container"></div>, and you :
document.write.getElementById.innerHtml.

eg:

function createDataContainer(){
var div=document.getElementById('container');
if(div){return};
var div=document.createElement('div');
div.setAttribute('id','container');
document.getElementsByTagName('body')[0].appendChild(div);
}

If you: var item = new item
item = getElementById.innerHtml() {...
Okay, I am way past bedtime. Here is better explanation:

yeah, I wish I new this, LMAO:

Oh boy:

You don't have to create text links, this ias just an example I copied from DevShed: JavaScript Remote Scripting: Processing XML Files

You can assign anything as a var, then use it however, of course.
From above:

You can read this guy, he is the best one of many I have read, more advanced, but very clear:
Alejandro Gervasio

THIS: JavaScript Remote Scripting: Fetching Server Data with the DOM

Basically, what I have been doing, is getting individual sets and assigning them by each as they come:
document.getElementById("id_name").innerHTML(){
if(is==good){
blah;
}
else(is_not_good){
other blah;
}}

document.write=nextRoundIsOnMe.getWalletByLocation ;o)))

 

Basically, what BurgerKing said

 

Here, I grab a ton of stuff, all from one xml file, and assign it to three different places(marker points, sidebar, hidden div[info window]):

Thanks guys for all your help.
I've got this code so far, however, it seems like nothing is getting returned in the array. The alert keeps returning undefined...can someone please help me.

  function submitSave()
  {
     var iarray  = new Array();

     for (i=0; i<numItems; i++) 
     { 
         iarray[i] = document.getElementById("textfields").value;  
         alert(iarray[i]);
     } 
  }

Hi,

The code you are using assumes that all the fields you want to read are called

textfields0
textfields1
textfields2
textfields3

etc. If your fields are called txtFirstName, txtLastName, txtAddress etc - then this will not work.

Also, the code assumes you have a global variable called numItems, and that it is set to something higher than 0.

Hope this helps. How about posting a more complete example?
