JavaScript - Getelementbyid().innerhml=

http://johnathany.com/contact.html

What I'm trying to do is get the googlemaps iframe to change if i hit to corresponding 3 links at the bottom.

So I tried to use getElementById(leftcolumn).innerhtml to change the entire content of the div but it isnt working.
Please advise.

Or would there be a simpler solution like creating 3 hidden divs and just do display:block; to display them?

I'm working on a web site: http://84.9.221.75/domains/backingtr...usicindex.html

I'm trying to get the Javascript that controls the scrolling text to scroll on both the left and right sides.....right now it only scrolls on the left, due to the use of getElementById() from what i can see....

So I'm trying to make the javascript see all references to the ID in the document, and make the right panel div scroll as well, but I'm not having any luck....

I have a very basic understanding of Javascript, so I need a little help here guys...thanks..

Hi,
I asked this question in an earlier post where Dormilich asked me to post the code, which I did twice but for some reason it hasn't posted so I'll try with a new thread....

I am passing a variable to a function in a separate .js file using embedded HTML.
I want to use the parameter in a getElementById but I can't get it to work.

Here's my HTML:
Code:

<SCRIPT LANGUAGE="JAVASCRIPT" TYPE="TEXT/JAVASCRIPT"> 
<!--
window.onload = function ()
{
initSlideDownMenu("accordionactivity");
}
//-->
</SCRIPT>

Here's my javascript function. When the first alert pops up I get 'accordionactivity', when the second one pops up I get '[object]' but when the third one pops up I get 'null'.The rest of the function then doesn't work properly either:
Code:

function initSlideDownMenu(slMenuName)
{

alert(slMenuName);
alert(document.getElementById('accordionactivity'));
alert(document.getElementById(slMenuName));

 dhtmlgoodies_slmenuObj = document.getElementById(slMenuName);
 dhtmlgoodies_slmenuObj.style.visibility='visible';
 var mainUl = dhtmlgoodies_slmenuObj.getElementsByTagName('UL')[0];  
 var mainMenuItem = mainUl.getElementsByTagName('LI')[0];
 mainItemCounter = 1;
 while(mainMenuItem){   
  if(mainMenuItem.tagName=='LI'){
   var aTag = mainMenuItem.getElementsByTagName('A')[0];
   var subUl = mainMenuItem.getElementsByTagName('UL');
   if(subUl.length>0){
    mainMenuItem.id = 'mainMenuItem' + mainItemCounter;
    initSubItems(subUl[0],2);
    aTag.onclick = showSubMenu;
    mainItemCounter++;
   }    
  }   
  mainMenuItem = mainMenuItem.nextSibling; 
 }  
 if(location.search.indexOf('mainMenuItemToSlide')>=0){
  var items = location.search.split('&');
  for(var no=0;no<items.length;no++){
   if(items[no].indexOf('mainMenuItemToSlide')>=0){
    values = items[no].split('=');
    showSubMenu(false,document.getElementById('mainMenuItem' + values[1])); 
    initMenuIdToExpand = false;    
   }
  }   
 }else if(expandFirstItemAutomatically>0){
  if(document.getElementById('mainMenuItem' + expandFirstItemAutomatically)){
   showSubMenu(false,document.getElementById('mainMenuItem' + expandFirstItemAutomatically));
   initMenuIdToExpand = false;
  }
 }
 if(expandMenuItemByUrl)
 {
  var aTags = dhtmlgoodies_slmenuObj.getElementsByTagName('A');
  for(var no=0;no<aTags.length;no++){
   var hrefToCheckOn = aTags[no].href;
   if(location.href.indexOf(hrefToCheckOn)==0 && (location.href.length==hrefToCheckOn.length || 

location.href.indexOf('?')==hrefToCheckOn.length)){
    initMenuIdToExpand = false;
    var obj = aTags[no].parentNode;
    while(obj && obj.id!=slMenuName){
     if(obj.tagName=='LI'){       
      var subUl = obj.getElementsByTagName('UL');
      if(initialMenuItemAlwaysExpanded)alwaysExpanedItems[obj.parentNode] = true;
      if(subUl.length>0){        
       objectsToExpand.unshift(obj);
      }
     }
     obj = obj.parentNode; 
    }
    showSubMenu(false,objectsToExpand[0]);
    break;     
   }   
  }
 }
 if(initMenuIdToExpand)
 {
  objectsToExpand = new Array();
  var obj = document.getElementById(initMenuIdToExpand)
  while(obj && obj.id!=slMenuName){
   if(obj.tagName=='LI'){
    var subUl = obj.getElementsByTagName('UL');
    if(initialMenuItemAlwaysExpanded)alwaysExpanedItems[obj.parentNode] = true;
    if(subUl.length>0){      
     objectsToExpand.unshift(obj);
    }
   }
   obj = obj.parentNode; 
  }
  showSubMenu(false,objectsToExpand[0]);
 }
}

Can you help me figure out what I'm doing wrong?
Thank you!

Hi there,

So I got this problem, and can't seem to figure it out myself.
I'm using JS ( no framework ). And that's the whole point of this script, so don't tell me to use one :P

Code:

var i=1;
var x=10; // Number of extraContent linked with extraContainers
for (i=1;i<=x;i++)
  {
	var content = "extraContent" +i;
	var container = "extraContainer" +i;
    document.getElementById(container).appendChild(document.getElementById(content));
  }

The problem here, that the container/content, in the getElementById will not return: extraContainer1/extraContent1

Any suggestions :)

Hello.

I'm trying to change the text on my page dynamically using getElementById etc. Just not quite sure how to do it.

Code:

<script>

function changeIt() {
document.getElementById('change').innerHTML = '*i want the stuff below here (from 'var' to 'text')*';
}

var Result= ((correct / 5) * 100) + '%';
document.write('<p>Result<b>' + score + '</b></p>');
					
document.write('<p>some text</p>');
</script>


//
<div id = "change">
*all the info I'm going to replace*
</div>

Just need to know how to put the variables and stuff in the 'innerhtml' part?

Thanks.

I have a html file and a separate javascript file.

The html file contains: <input type="reset" id = "resetButton" />

I want a message to pop up if the reset button is pressed.

So in the js file I have:
document.getElementById("resetButton").onclick = doAlert;

doAlert is a function that simply does: alert("Do you want to reset?");

I know my separate js file is linked correctly because if I just put in alert("hello"); in the js file then it works. But if I use the document.getElementById thing in the js file, then there is an error. The error, according to the error console, says that "resetButton" is null. Can someone help me? thanks!

btw, I'm totally new to programming...and I need to do this for my homework assignment

why is getElementById not working?? pls try it and tell me if you get a hit on
document.getElementById("t1");


thanks

Hey guys,

Thanks for taking the time to read my post. I am not new to programming or scripting, but I am completely new to javascript and web-based code. Hopefully you guys could help me understand what is going on and maybe help me figure out what I am trying to do.

What I am trying to do:
-There is an element that has a value
<td class="flashField" onmouseover="clearAnswer()">
<div id="flashAnswer" onmouseover="clearAnswer()">answer string here</div>
</td>

-There is a text box that needs to have the answer above given to it
<td class="flashField">
<input type="text" tabindex="1" onkeypress="clearAnswer()" name="q" maxlength="256" size="50">
</td>

-There is a next button that needs to be executed
<td align="right">
<input type="image" tabindex="2" alt="Next" src="http://website.com/images/next.gif">
</td>

So what I am trying to do is create a script through Greasemonkey that will automatically do these things. I am starting small and trying to just get the value of flashAnswer to appear as an alert on the screen by using this code:
var answer = document.getElementById('flashAnswer');
alert(answer);

But the problem is it posts some weird value ([object XrayWrapper [object HTMLDivElement]]) that most definitely is not "answer string here" and is a bit above me at this point. Any ideas?

Any help would be great guys!

Thanks!

What I'm trying to get are the tag ids separately after I call the callback function. I've been racking my brain for far too long on this one. Here is a shorter version of what I have. I'm using the array's length to count and break into their own lines.

How do i get all 9 id="hover_[index]" separately using my array length?

PHP Code:
var info = Array("bla_1", "bla_2", "bla_3", "bla_4", "bla_5", "bla_6", "bla_7", "bla_8", "bla_9");

function callback(results, status) {
    if (status == myStatus) {
        for (var i = 0; i < results.length; i++) {
            send(results[i]);
        }
    }
} 
function send(info) {    
    document.getElementById('results').innerHTML += "<div id='hover_"+info.length+"'>Something</div>";
    hover_target = document.getElementById('hover_'+info.length);// how do i get all 9 hover_[index] separately?
    someEvent.addDomListener(hover_target, 'mouseover', function() {
        // do something
    });
} 


Thank you so much in advance,
Frank

I have some simple javascript code that works fine in chrome and safari, but not Ie8

Code:

<head><script type="text/javascript">
function val2() {
	//var num = Number(document.getElementById('PdRows').value)
	alert (document.getElementById('PdRows').value)
}
</script></head>

<form action="" method="post">
<select name="PD" id="PdRows" onchange="val2()">
  <option>1</option>
  <option>2</option>
  <option>3</option>
  <option>4</option>
  <option>5</option>

for(var k=1;k<=crpt;k++)
{
qtyc = document.getElementById("txtRowc3"+k).value;
unit_pricec = document.getElementById("txtRowc5"+k).value;
alert('QTYC:'+qtyc+' UPC:'+unit_pricec);
cttl = qtyc * unit_pricec;
document.getElementById("txtRowc6"+k).value = cttl.toFixed(2);
csbttl = csbttl + cttl;
}
document.getElementById("subttlC").value=csbttl.toFixed(2);

it shows the value of textRowc3i in qtyc in alert box but also givs error document.getElementById("txtRowc3"+k) is null..
I tried for this but problem is not solved please help... Thank You...

Hello,

I need to do this. I have 36 Divs called "contenido1, contenido2, contenido3 etc.)

And I want that "onclick" change a property of the css of all of them except 1. I know I can do this manually but its a lot of code lines so I think it would be another option to do ir in a loop.

Right now i am using this:

Code:

div = document.getElementById('contenido1');
div.style.display='block';
div = document.getElementById('contenido2');
div.style.display='none';
div = document.getElementById('contenido3');
div.style.display='none';
div = document.getElementById('contenido4');
div.style.display='none';
....

So in that case I want for example that all the DIVS called "contenido 2 to contenido 36" display: none and only contenido 1 display block. In the next cases would be the same: All the divs called "contenido 1 to contenido 36" display: none except "contenido 2" that i want to display: block.

So I can do it like this but are thousands of lines of code... and I am sure there are other more efficient option.

Anybody knows how to do that? Probably is a simple question.

Thank you!!

Hi, quick question:

Code:

function x() {
	document.getElementById('myid').width += 200;
}

This works for "myid", but my document contains "myid1", "myid2", "myid3", and so forth. How can I alter the script to effect every instance of "myid" followed by a number?

Hi,

I am new to javascript. Been picking up bits and parts but am bumping my head against walls.
Have table with 4 cols and 2 rows - header row and 2nd row with 3 input text boxes and 1 option list. Have an array to adds rows to table when user clicks button-max-3 more rows. Option list not a problem-propagates values. Row 1 - 1st and 2nd input boxes linked to JQuery for datapicker and 4th calls js validation for numeric input.
When user adds row those links are not there-which is what I need. Array cites input boxes with name and iteration of +1 for each added row. Should I use, in the array,
document.getElementById('startdate0'; document.getElementById('startdate1'); etc., or should I use keyword this? And if I use this, how is it applied?
I do not know how to declare these variables for recognition. Tried several methods without success.
Following is array:
Code:

<script language="Javascript" type="text/javascript">
/*<![CDATA[*/
		   
	var new_rows=new Array();
	var row_count=0;

     function addRow()
     {
          var tbl = document.getElementById('ReqDtTbl');
		  new_rows[row_count]=new Array();
          var lastRow = tbl.rows.length;
          var iteration = lastRow;
		  if (lastRow>4){
			  return;}
          var row = tbl.insertRow(lastRow);
		  var cellLeft = row.insertCell(0);
          var textNode = document.createElement('input');          
		  textNode.size = 7;
		  textNode.name = 'startdate' + iteration;		  
          cellLeft.appendChild(textNode); 
		  new_rows[row_count]['cell']=textNode;
          var cellRight = row.insertCell(1);          
          var el = document.createElement('input');          
          el.type = 'text';          
          el.name = 'enddate' + iteration;          
          el.id = 'enddate' + iteration;          
          el.size = 7; 
		  new_rows[row_count]['cell2']=el;
          cellRight.appendChild(el);          
          // the last cell!
          var cellRightSel = row.insertCell(2);          
          var sel = document.createElement('select');          
          sel.name = 'TypeHrs' + iteration;          
          sel.options[0] = new Option('-Select-', '""');
          sel.options[1] = new Option('Comp Time', 'Comp Time');
          sel.options[2] = new Option('Credit Hrs', 'Credit Hrs');
		  sel.options[3] = new Option('Overtime', 'Overtime');
		  sel.options[4] = new Option('Rel Comp', 'Rel Comp');          
          cellRightSel.appendChild(sel);
		  new_rows[row_count]['cell3']=sel;
		  var cellRight = row.insertCell(3);          
          var el = document.createElement('input');          
          el.type = 'text';          
          el.name = 'No. of Hours' + iteration;          
          el.id = 'No. of Hours' + iteration;          
          el.size = 7;         
          cellRight.appendChild(el);
		  
		  new_rows[row_count]['cell']=el;
		  row_count++;
     }
     function removeRow()
     {
          // grab element again
          var tbl = document.getElementById('ReqDtTbl');
          // grab length
          var lastRow = tbl.rows.length;
          // delete last row if there is more than one row
          if (lastRow > 2) tbl.deleteRow(lastRow - 1);
     }
	 /*]]>*/
</script>

Input box for date is:

Code:

<input style="width: 70px" type="text" id="startdate">

Function is:

Code:

<script type="text/javascript">
$(function() {
		$("#startdate").datepicker();
		$("#enddate").datepicker();
		$("#RcompStart").datepicker();
		$("#RcompEnd").datepicker();
	});
</script>

Input for numeric is:

Code:

<input type="text" name="No. of Hours" id="No. of Hours" style="width: 70px;" onblur="checkQuarters(this);" />

And numeric validation function is:

Code:

<script type="text/javascript">
function checkQuarters( fld )
{
    var val = parseFloat(fld.value);
    if ( isNaN(val) || ( val*4 != Math.floor(val*4) ) )
    {
        alert("Value must be a numeric and a multiple of 0.25");
        return false;
    }
    return true;
}
</script>

Thanks - John

I've spent three days trying to figure this out without any luck.
What i am attemping to do is to open an unframed tab using the link from a frame id. I want to be able to enter a js command in the browser on the page then have it open in a new tab unframed or just reload the link unframed. These are the commands i have tried in my browser:


javascript:<a herf="document.getElementById("netlinkx").childNodes[1].src;">

javascript:<a herf="window.location.href=document.getElementById("netlinkx").childNodes[1].src;">

javascript:<a herf=document.getElementById("netlinkx").children[0]>.setAttribute('id','this_one');alert(getFrame("this_one").body.innerHTML);>

and a few others that didn't work.
