JavaScript - "listen" For Specific Button Click - Then Redirect?

Hi All,

I am very new to HTML programming and Javascripts.

What I am trying to accomplish is I have a radio button "RequiredApprovalYesNo". When the selection is "Yes", I need fields "Approver" and "ApproverEmail" to be required upon submit. I also need to make sure that a selection is made with this radio button of either Yes or No.

Here is my HTML code for these three fields and was wondering if someone could show me how to code this script or, give me an example of a Radio button selection resulting in additional fields being required or not.

Thank you in advance.

Code:

<td>
  <input type="radio" name="RequireApprovalYesNo" id="RequireApprovalYesNo" value="Yes">Yes
                
  <input type="radio" name="RequireApprovalYesNo" id="RequireApprovalYesNo" value="No">No
                </tr>
              <tr>
                <td><table width="190" border="0" align="right" cellspacing="0">
                  <tr>
                 </tr>
                </table></td>
              <tr>
                <td colspan="3"><div align="left"><em><strong><b style= 'color: red;'>If Yes, You Must Enter an Approver with a corresponding Email:</b> </strong></em></div></td>
                </tr>
              <tr>
                <td height="25"><div align="right">Approver:</div></td>
                <td>&nbsp;</td>
                <td><input name="Approver" type="text" id="Approver" size="40";"></td>
              </tr>
              <tr>
                <td height="25"><div align="right">
                  <p>Approver's Email: </p>
                  </div></td>
                <td>&nbsp;</td>
                <td><input name="ApprovalEmail" type="text" id="ApprovalEmail" size="40"></td>
              </tr>
              <tr>

Hello,

I'm not really a techie but I was feeling a little adventurous this morning so I thought I'd try to follow some tips online to customize a "buy" button for some products that I'm preparing to sell online at what is currently: www.SensoryEscapeImages.Squarespace.com

If you visit this site, then click on "Photo Gallery" on the top nav, then click on the 4th image to the right on the top row of thumbnails, you will see on the overlay, at the bottom, three dropdowns that I'm trying to affect.

So, there are three fields presented with the Buy button: Size, Format, and Trim & Finish. If I were to select the Size of 8 x 12 in the first dropdown, the behavior that I am striving for is to only show the Formats available in that size in the second dropdown. Subsequently, each format has Trim & Finish options exclusive to that format and I'm aiming to only make those show in the Trim & Finish dropdown.

But it aint working. Here's the code that I started. No laughing

Apart from any logical mistakes this thing i have created might have , my question is this.Why upon pressing the last button and calling the "scor(j)" function , no alerts pop up?Thanks in advance. I'm completely stumbled by this as i have no clue as what might be wrong.But then again , my experience is extremely limited

I am trying to add a pulldown menu with a button to my website. I have successfully done this with a javascript I found online here to give credit:
http://www.blazonry.com/javascript/js_menu.php
I tried to modify the form so it will use an image file instead of the default button. To troubleshoot I took the relevant code and put into a seperate html file. This one is using the default code from the site referenced above. This is the page published online:
http://www.keylimecomputerservice.com/test/default.html

Code:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">

<head>

<SCRIPT LANGUAGE="JavaScript"><!-- 
function openURL()
{ 

// grab index number of the selected option
selInd = document.theForm.aaa.selectedIndex; 

// get value of the selected option
goURL = document.theForm.aaa.options[selInd].value;

// redirect browser to the grabbed value (here a URL)
top.location.href = goURL; 

}

//--> 
</SCRIPT>

</head>

<body>

<TABLE SPAN="3" BORDER=1 CELLSPACING=0 CELLPADDING=0 align="center" WIDTH="60%">
	<TR>

		<TD WIDTH="33%">
		<center><font color="black">Choose a connection</font></center><br>
		<form name="theForm"> <tt>
		<center>
		<select name="aaa" size="1">
		<option selected value="#"> ---------- </option>
		<option value="/remote/connect1.exe">Connection 1</option>
		<option value="/remote/connect2.exe">Connection 2</option>
		<option value="/remote/connect3.exe">Connection 3</option>
		<option value="/remote/connect4.exe">Connection 4</option>
		<option value="/remote/connect5.exe">Connection 5</option>

		</form>
		</TD>

		<TD WIDTH="33%">
		</TD>
	</TR>
</TABLE>

</body>

I then tried to change the form to use an image instead of the default button. Obviously I didn't do it right. THIS ONE DOES NOT WORK. When you choose a menu item and then click the image, it just refreshes the page.

I am trying to manipulate a an image gallery that functions well. Now, I have the ability to pull information from a user's preference pannel and need to place it in the an href="" // And other information in each of the "src" | "url" | "alt".
Any ideas would be truly helpful. This is what I am working with at the moment and it doesn't work (obviously because it is adding code inside a span). Here is what I am starting from:
[CODE] var title01Span = document.getElementById('title01Span'), //Finds the id that I want
prefs = new gadgets.Prefs(), // Pulls from the user's preferences
yourtitle01 = prefs.getString("title01"); // Pulls the correct string from those preferences
title01Span.innerHTML = yourtitle01; // replaces the span.id with that text but I need to be able to do this in the src / href / url / etc.
[CODE]
Thank you so much! I seriously could use as much help as possible!

Hi guys what i'm trying to do without sucess , can't find anything on google.. Is trying to arrange a button to do a "CTRL+T" (Select all) effect in the HTML i'm currently viewing. Is this possible in Javascript?

I dont want to select the text in a textbox ! I want it in the whole .html i'm currently viewing.


Cheers

Code:

window.onload = initForms;

function initForms(){
	for(var i=0; i<document.forms.length; i++){
		document.forms[i].onsubmit = function(){
			return validForm();
			}
		}
	}

Hi, this is the first part of a long code and I have three questions wondering if anyone could help me..
1. What is the benifit of having the above code with "window.onload" and "for loop" and loop through the forms if I only have ONE form in html?

2. What is this line of code "document.forms[i].onsubmit" saying? Does it mean "Execute function() when submit button within form[i] has been pressed?"

3. function() - Does this empty function mean "run every following function below"?? Thank you!!

Hey guys.

New here on the forum, and writing in desperate need for help! I tried the search, but couldn't come up with an answer for my question.

I am running a clothing webshop with a CMS based on ASP. I would like to add a "Back" button on every 'product page' (PP), leading back to the latest 'product list page' (PLP). My problem is that the supplier of the CMS does not support AJAX, which leaves me with a page that is refreshed (and therefore stored as refer-URL) every time I select a different color, size or picture on the PP. My original thought was to add the 'Back' button and make it link to the selected menu point in the left (which could be brand, size, pants, shirts etc.) however, I came to the conclussion that this would be a bad solution, since under the category 'Pants' I'd have 6-7 pages of pants, so if a user was on page 4 and entered the PP for a pair of pants and pressed the 'Back' button, the user would be taken back to page 1.

Therefore I am looking for a solution that will let me go back x number of steps, until on the previous PLP. To my knowledge ASP only supports reffer URL and not reffer URL of the reffer URL. ?

Now, the URL for PLP's have 'pl' embeded in them, where the URLs inside the PP have 'pi' embeded in them, I don't know if that is usable somehow?

Is there a JS fix for this in any way?

Thanks in advance.

Best regards.

Hi, I want the user to choose one option in each of the radio group. But when I click only one button out of all 12 buttons, it allows the user to submit. How do I change it to a way that the user must click one option for each group in order to allow him/her to submit the form?

Javascript
Code:

function valbutton(thisform) 
{
    // place any other field validations that you require here
    // validate myradiobuttons
    myOption = -1;
    for (i=thisform.myradiobutton.length-1; i > -1; i--)
    {
        if (thisform.myradiobutton[i].checked)
        {
            myOption = i; i = -1;
        }
    }
    
    for (i=thisform.myradiobutton1.length-1; i > -1; i--)
    {
        if (thisform.myradiobutton1[i].checked)
        {
            myOption = i; i = -1;
        }
    }

    for (i=thisform.myradiobutton2.length-1; i > -1; i--)
    {
        if (thisform.myradiobutton2[i].checked)
        {
            myOption = i; i = -1;
        }
    }

    for (i=thisform.myradiobutton3.length-1; i > -1; i--)
    {
        if (thisform.myradiobutton3[i].checked)
        {
            myOption = i; i = -1;
        }
    }
    
    for (i=thisform.myradiobutton4.length-1; i > -1; i--)
    {
        if (thisform.myradiobutton4[i].checked)
        {
            myOption = i; i = -1;
        }
    }

    for (i=thisform.myradiobutton5.length-1; i > -1; i--)
    {
        if (thisform.myradiobutton5[i].checked)
        {
            myOption = i; i = -1;
        }
    }                    

    if (myOption == -1) 
    {
        alert("You must select a radio button");
        return false;
    }

    // place any other field validations that you require here
    thisform.submit(); // this line submits the form after validation
}

I'm looking for something, preferably JQuery, that will let me load new content (blog posts) when "View More" is clicked. Something with a smooth animated motion would be nice. Any tutorials or info on what this technique is called?

Hi all, I'm having a bit of a problem..

Hello, I run a online gaming website, and I'm having problems with certain websites iframing our games.

Actually I'm ok with iframing, as long as they include the banner ad located just beneath our games. But often times unscrupulous webmasters will iframe only the game, preventing us from generating any revenue from the banner ad (and costing us additional bandwidth charges).

I'm hoping to find a way to detect the dimensions of the iframe, so that I may dynamically resize the game, in order to include the banner ad within the iframe. Does anybody know how to extract the "height" and "width" attribute values from an <iframe> tag sitting on a different site?

Regards,
Steve

Hello,
recently I have been to many government websites where I have noticed that the programmer has used window.open() method in JavaScript to link to different pages instead of using <a> tags!

I was just getting curious to know whether it is normal or has it been used due to security concerns(if any, I don't know)?

Any comments?

Hi guys,

I have a JS calculator on my website which is basically a load of radio buttons that the user clicks and as they do so a price is calculated in their view.

At the moment - the price box starts with a blank box but is essentially "0". Then, as the user select an option, the price appears and then starts to calculate when more than 1 is pressed.

All I want to do is have the price start at "300" instead of a blank box or "0". Then the rest of the options calculate onto that. I have tried a variety of ways to achieve it and seem to be missing something! I am pretty new to JS although do have a basic understanding ..... clearly not enough to do this thou! lol

Basically imagine 300 is the initial price. That only gets charged once ...

Here's my code ....


In the <head>

Code:

<script type="text/javascript">

function getRBtnName(GrpName) {
  var sel = document.getElementsByName(GrpName);
  var fnd = -1;
  var str = '';
  for (var i=0; i<sel.length; i++) {
    if (sel[i].checked == true) { str = sel[i].value;  fnd = i; }
  }
  return fnd;   // return option index of selection
// comment out next line if option index used in line above  
//  return str;
} 

function chkrads(rbGroupName) {
  var ExPg = [
	  [0,''], 
	  [100,"1 extra page"], 
	  [200,"2 extra pages"], 
	  [250,"3 extra pages"],
	  [300,"4 extra pages"],
	  [350,"5 extra pages"]
  ];
  var ExEm = [
	  [0,''], 
	  [10,"1 extra email"], 
	  [20,"2 extra emails"], 
	  [30,"3 extra emails"], 
	  [40,"4 extra emails"], 
	  [50,"5 extra emails"]
  ];
  var ImgBun = [
	  [0,''], 
	  [10,"3 extra image"], 
	  [20,"5 extra images"], 
	  [30,"7 extra images"], 
	  [40,"10 extra images"]
  ];
     var rbtnGroupNames = ['extrapages','extraemail','imagebundles'];
  var totalprice = 0;
  var tmp = '';  var items = [];
  for (var i=0; i<rbtnGroupNames.length; i++) {
	tmp = getRBtnName(rbtnGroupNames[i]);
	if (tmp != -1) {
 	 switch (i) {
	  case 0 : totalprice += ExPg[tmp][0]; if (tmp > 0) { items.push(ExPg[tmp][1]); } break;
	  case 1 : totalprice += ExEm[tmp][0]; if (tmp > 0) { items.push(ExEm[tmp][1]); } break;
	  case 2 : totalprice += ImgBun[tmp][0]; if (tmp > 0) { items.push(ImgBun[tmp][1]); } break;
	 } 
	}
  }
  document.getElementById('QUOTED_PRICE').value = totalprice;
  document.getElementById('ITEMS_SELECTED').value = items.join('\n');
  document.getElementById('PRICE_IN_VIEW').innerHTML = totalprice;
}

function validate() {
// add any required validation code here prior to submitting form
  var allOK = true;
// if any errors found, then set 'allOk' to false;
  return false;		
// after testing with validation code, change line above to: return allOK;
}

</script>

And then the <body>

Code:

<form name="radio_buttons_startup" id="radio_buttons_startup">

i am trying to make a comment editor with iframe, and want to trigger the change of content inside iframe, the following code cant work.

it is strange because it works fine when i replace them with "keypress" and "blur"

Code:

<iframe id="iframe"></iframe>

<script>

frameobj=document.getElementById('iframe').contentWindow; 

// IE
frameobj.attachEvent('onpropertychange', function(){alert();} );

//FireFox
frameobj.addEventListener('input', function(){alert();} , false);

</script>
