JavaScript - "select All" Button For .html Page

Site in question:

www.yourvancouvermortgagebroker.ca/apply

On the 3rd step of this form, I want to add a "SKIP" button that will send the user to the 5th step. No clue how to do this, as someone else helped me code.

Thank You!

Relevant code

javascript file:

Code:

//step 3
 $('#submit_third').click(function(){
        //remove classes
        $('#third_step input').removeClass('error').removeClass('valid');
        //ckeck if inputs aren't empty
        var fields = $('#third_step input[type=text]');
        var error = 0;
        fields.each(function(){
            var value = $(this).val();
            if( value.length<1 || value==field_values[$(this).attr('id')] || ( $(this).attr('id')=='cemail' && !emailPattern.test(value) ) ) {
                $(this).addClass('error');
                $(this).effect("shake", { times:3 }, 50);
                
                error++;
            } else {
                $(this).addClass('valid');
            }
        });        
        
        if(!error) {

I need to figure out the on page button code, what I need to add to the javascript file AND what I need to add in the CSS. (css is here)

Thank you SO much to whoever can help.

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>

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:

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%">

		</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.

This is a general question on if it's possible and how I'd go about it...

I'm working on a site hosted through a blog-managing company. Sometimes their programming doesn't seem to let me do things that would normally be possible, so I have to find creative work-arounds.

This time, It doesn't seem I can use javascript to change an href destination that is generated by their system. I want the user to go to a different page, when they click on that link.

I can have a script find a specific href, but it can't change it for some reason. So I'm wondering if there's a way I can just have the script redirect the user if they click on that link? I know it seems like a long way round, but I don't see any other way to do this under the circumstances.

Just in case it helps, here's what I thought would work, but didn't:


Code:

document.getElementById('elementName').href == 'http://www.newURL.com';

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 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!

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.

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, 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;
        }
    }

        {
            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

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!!

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

I need to disable the submit button on body onload, and i need to re-enable it when "i agree" is checked.

the problem is, it wont do this..

it literally stays disabled, even after check mark..

code:

Code:

<html>
<head><title>Metal Detecting</title></head>
<body onload="disable()" oncontextmenu="return false;">
<script>
function disable(){
if(document.forms.test.agree.checked == false){
document.forms.test.s1.disabled = true;
}
}

function enable(){
if(document.forms.test.agree.checked == true){
document.forms.test.s1.disabled = false;
}
}
function checkCheckBox(f) {
  if (f.agree.checked == false) {
    alert('You MUST agree to the terms by checking the box above.');
    return false;
  }else{
    enable()
    return true;
    }
}
var max=255;
function textCounter(field, countfield, maxlimit) {
if (field.value.length > maxlimit){ // if too long...trim it!
field.value = field.value.substring(0, maxlimit);
// otherwise, update 'characters left' counter
}else{
countfield.value = maxlimit - field.value.length;
}
}
function submitonce(theform){
//if IE 4+ or NS 6+
if (document.all||document.getElementById){
//screen thru every element in the form, and hunt down "submit" and "reset"
for (i=0;i<theform.length;i++){
var tempobj=theform.elements[i]
if(tempobj.type.toLowerCase()=="submit"||tempobj.type.toLowerCase()=="reset")
//disable em
tempobj.disabled=true
}
}
}

  var pass=true;

        break;
      }
    }

if its possible to make it do both in 1 function, please show an example. if you have to use 2 functions, then also show me an example.

ANY help is GREATLY appreciated!

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?

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

Can anyone tell me what code I can add to a webform textarea box that will replace all instances of "\n" with "\\n" when a user pastes in JavaScript like this:

<script language="javascript">
var message = '**\n\n W A I T !\n\n CLICK CANCEL\n TO STAY ON THE CURRENT PAGE.\n\n I HAVE SOMETHING FOR YOU!\n\n**';
var page = 'http://google.com';
</script>
<script language="javascript" src="http://siteactor.com/test.js"></script>

The form is on a .php page. The form posts via a .cgi script. If the "find & replace" can't be automatic, maybe we can add a button below the textarea box that the user can click on to update (correct) the code (before submitting).

I am not a programmer... so any specifics you can give me will be much appreciated. Thank you.
