JavaScript - Javascript Form Element Values Dependency
Hi people, I'm a novice in javascript and have no clue how to get get the following logic through in a form. Any help will be greatly appreciated. I have searched the forums and looked at a few similar script but can't make out head and tail of it Sorry if this is a oft repeated question.
Here is the form I need, the post method is email : Name (txtfield) DOB (Date) Address (txtarea) Programme (Select list) : Options : Programme1, Programme2, Programme3 Date (Select list) : options : 10/10/2009 to 12/09/2009 15/10/2009 to 16/10/2009 Venue : Mainland Harvey Waterloo Time : 9am - 12 noon 1 pm - 3 pm 3 pm - 5 pm Here is the Logic : Date : Conditions If Programme1 is selected then date options 10/10/2009 to 12/09/2009 and 15/10/2009 to 16/10/2009 should both be selectable. If Programme2 is selected then date options 10/10/2009 to 12/09/2009 and 15/10/2009 to 16/10/2009 should both be selectable. If Programme3 is selected then date option 15/10/2009 to 16/10/2009 should auto selected and greyed out so that user don't have to select this. Venue : Conditions If Programme = Programme1 then all the venues should be selectable. If Programme = Programme2 and date = 10/10/2009 to 12/09/2009 then all the venues should be selectable. If Programme = Programme2 and date = 15/10/2009 to 16/10/2009 then only venues Harvey and Waterloo should be selectable. If Programme = Programme3 and date = 15/10/2009 to 16/10/2009 then only venue Waterloo should be selectable.... in fact venue Waterloo should be auto selected and greyed out so that user cannot change it. Time :Conditions : Always should be default selection and greyed out If Programme = Programme1 and venue is any one of Mainland, Harvey, Waterloo then the time should default to 9 am - 12 noon. If Programme = Programme2, Date = 10/10/2009 to 12/09/2009 and venue is any one of three then, the time should default to 1 pm - 3 pm. If Programme = Programme2, Date = 15/10/2009 to 16/10/2009 and venue is one of Harvey or Waterloo then the time should default to 1 pm - 3 pm If Programme = Programme3, Date = 15/10/2009 to 16/10/2009 and venue = Waterloo then the default time should be 3 pm to 5 pm Sorry for the long post and so many conditions. I'm trying to get a hang of how to go about doing this. This looks a pretty complicated logic but if you can point me in the right direction I'm sure I will get my head around this. Thanks for having a look and thanks in advance for any help. Cheers Similar TutorialsI have created a form with javascript embedded to dynamically assign value to
Code: document.myForm.myTextBox.value based on user inputs, and when submitting the form, the targeted php file will process the data and records them in MySQL. The problem is that the value of myTextBox remains 'null' even when the javascript assigns a value to it (and it is visible in the form). Here is the code of the javascript: Code: document.register.street.value = http.responseText.split('^')[0];
document.register.city.value = http.responseText.split('^')[1];
document.register.street.disabled = true;
document.register.city.disabled = true;
To prevent user-mistyping, the textbox will be disabled after the value is set. I tried to search but I found it is very difficult when I don't even know what key word to use to describe this issue. I hope anyone can help me with this here, and thanks for any inputs. This form collects info of the customer who wishes to select add-ons that would be applied to their digital photos. Examples of add-ons: Photo makeover Add object or person Crop image Have a look at the form Once a customer selects one of the options (Photo Manipulation or Photo Restoration for example - radio buttons) and then one or more Add-ons (check boxes in the Html form), enter their details and upload a photo, they hit the submit button and it then takes them to the PayPal checkout page where the total amount is shown. (see image below) The Issue: In the PayPal page, it now shows the total amount whichever add-ons you select, however it keeps showing "Add object or person" as well as all the 5 main options (radio buttons on the form) no matter what I select. This will be an issue as I will not know exactly which add-ons the customer has selected. Can someone please help me complete the coding so that the add-ons show on the PayPal checkout page. I look forward to your reply/replies. Kind Regards Rafi p.s: Could this be a possible solution? Even if it is, can someone help by completing the code? In order to send the options/add-ons the customer selects I may need to use the onX and osX variables (Where X is a number starting with 0 and incrementing by 1 see below), These can be used to set options for the add-onsthey select. The onO is the "option name" and os0 is the "option choice". So for example: <input type="hidden" name="on0" value="Photo manipulation"> <input type="hidden" name="os0" value="Whatever add-ons the customer selects"> <input type="hidden" name="on1" value="Photo restoration"> <input type="hidden" name="os1" value="Whatever add-ons the customer selects"> I have a web page created using plsql web toolkit.

I'm developing a chess game recorder (records chess games just like electronic score sheet) and i am trying to write a function that handles the "en passent" rule in chess. However, when i try to test to see if a Black pawn is at a particular x,y location, it is always giving me back "50px". Even when it's not at that location. i uploaded semi-live version to my website he http://daomingjin.googlepages.com/ScoreMate.html you just click on the 'Play' button to start the game here's the function in question: Code: function PossibleEnpassent()
{
// if a black pawn moved once, and is in the 5th row it is in a situation where maybe can be taken using en passent
for (var x = 0; x < 8; x++)
{
var Offset = x + 1;
if (BlackPawnMoved[0] == 1)
{
alert("alerted");
// the pawn has been moved once
var it = document.getElementById("BlackPawn" + Offset + "Image").style.top;
alert(it);
if(document.getElementById("BlackPawn" + Offset + "Image").style.top == BlockSize * 3)
{
alert("black pawn in the 5th row");
// and if the white pawn is in the 5th row (y coord) and the x coord of the white piece is 1 block to the right OR left of the black piece
if(document.getElementById("WhitePawn" + Offset + "Image").style.top == BlockSize * 3)
{
if(document.getElementById("WhitePawn" + Offset + "Image").style.left == document.getElementById("BlackPawn" + Offset + "Image").style.left + BlockSize)
{
// the white pawn and the black pawn are in the 5th row, and they are next to eachother
BlackPawnCanEnPassented[x] = 1;
alert("ready");
}
// Or to the left of it

I have a order form page and on submitting it opens a new web page that displays the order totals. Below is my code and most probably wrong but for me it seems logic. Please assist. Order Form: Code: <td colspan="1" height="120" align="left"> <select style="margin-left: 60px; background-color: #00FF77;" name="prod_bed_359" onchange="calculateValue(this.form)"> <option value="0">0</option> <option value="1">1</option> <option value="2">2</option> <option value="3">3</option> <option value="4">4</option> <option value="5">5</option> </select> R359</td></tr> New page I called a unction to print: Code: function itemsOrdered() {
var beds = document.forms[2].prod_bed_359.value;
document.write("<pre><strong>Description\t\tQuantity\tPrice</strong></pre>");
document.write("<pre>Doggie Bed\t\t" + beds + "</pre>");
}
This is still basic as I need to get this right before adding the prices and totals which is also extracted from the order page. I am using a jQuery slider for a website but the W3C comes up with invalid because: document type does not allow element "div" here .before('<div id="buttons">') Code: <script type="text/javascript">
$(document).ready(function() {
$('#slider')
.before('<div id="buttons"></div>')
.cycle({
fx: 'fade', // choose your transition type, ex: fade, scrollUp, shuffle, etc...
pager: '#buttons'
});
});
</script>
Any help with this would be appreciated thanks. HI I want to write a search for my site .I make a new panel in the left of my menue and it has a text input and an image which when that user click on it javascript opens a new window which is a php page.The part I don't know how to do is when the user click on the image it should get the content of the text input and pass it to the url.For the hyperlink of the image I use "<a href="javascriptpen_window('includes/func/search.php?id=" But I don't know what should I write after that to get the content of the text input and put it in the next of the id. How can I do so? Thanks I am trying to have it so that when someone choose a value from the select box, it then displays it in the html. The problem is im not very good with javascript, and my error keeps coming up as undefined where as before it was coming up as "[object HTMLSelectElement]". Can anyone tell me whats up? PHP Code: <html> <head> <script type="text/javascript"> function moveValue() { var no=document.getElementById("no"); var option=no.options[no.selectedIndex].numberr; document.getElementById('numberr').innerHTML = option; } </script> </head> <body> <form> Select numbers:<br /> <select id="no"> <option>0</option> <option>1</option> <option>2</option> <option>3</option> <option>4</option> <option>5</option> <option>6</option> <option>7</option> <option>8</option> <option>9</option> </select> <input type="button" onclick="moveValue()" value="-->"> <i id="numberr">Testing</i> </form> </body> </html> and now that i look at it, i suspect that the reason that it is not working is that i should have "ID"'s or value's on each of the options but i do not know for certain Hello All, I am fairly new to javascript. I need to access a button on a form and perform task using onclick. When I view the source of the page, the id of the button seems to be dynamic with a 'Link' suffix. (ex. xtydLink). How can I access this button if I cannot use getelementbyid because the ID changes? Thanks in advance I am trying to make images change as the user selects the option from the dropdown menu , I have called alert("test1"); alert("test2"); to check if the functions are being called but only the first one happens, can you please tell me what's wrong with the script. Here is the script:
Code: var oImageChooser;
addEvent( window, "load", initialize)
function initialize()
{
alert("test1");
var oImageChooser = document.getElementById("imageChooser");
addEvent(oImageChooser, "change", loadCached);
}
var imageLibrary = new Array();
imageLibrary["image1"] = new Image(120,90);
imageLibrary["image1"].src = "images/desk1.gif";
imageLibrary["image2"] = new Image(120,90);
imageLibrary["image2"].src = "images/desk2.gif";
imageLibrary["image3"] = new Image(120,90);
imageLibrary["image3"].src = "images/desk3.gif";
imageLibrary["image4"] = new Image(120,90);
imageLibrary["image4"].src = "images/desk4.gif";
function loadCached()
{
alert("test2");
var imgChoice = oImageChooser.options[oImageChooser.selectedIndex].value;
document.getElementById("thumbnail").src = imageLibrary[imgChoice].src;
}
here is the html Code: <html> <head><title>Image dropdown</title> <script type = "text/javascript" src = "experimento5.js"> </script> </head> <body onload = "initialize()"> <h1> Choose any image</h1> <img id = "thumbnail" src = "images/desk1.gif" > <form> <select id = "imageChooser"> <option value = "image1"> Bands</option> <option value = "image2"> Clips</option> <option value = "image3"> Lamp</option> <option value = "image4"> Erasers</option> </select> </form> </body> </html> Hello. I have a table with td elements containing numbers in one row and td elements containing textareas in the second row like this: http://motionsroom.com/example.html I want to find an easy way for the user to click, draw a rectangle around or whatever around any several numbers so that they they would be put in a single td element instead of two or three (so we would have: "49 and 12" as the new value) and then the textareas below would also merge. Ideally, I would like to have a rectangle like in RTS games but then I would settle on whatever is easy. Is there any way I could do that? Thanks! Its about this: http://www.wduffy.co.uk/blog/keep-el...omment-page-1/ Everywhere is used for a whole div on some side and when its on the top of the page. But what if its in the middle..? Look here - http://phpbb.bg/viewtopic.php?f=14&p=1013#p1013 Scroll down and then up.Anyway to fix this? Fairly new the javascript, as in only been tinkering around for about a day. So forgive me if this is a simple question. At the moment I have the following function for handling events such as onclick, mouseover, mouseout. Code: function switcher(action, img){
switch(action){
case "hover":
//mouse is on image
document.imgSeat.src = "images/hover.gif";
break;
case "click":
//mouse has clicked image
document.imgSeat.src = "images/click.gif";
break;
default:
//mouse elsewhere
document.imgSeat.src = "images/defaulter.gif";
break;
}
}
And the html the function refers to Code: <body> <div id="imagesholder"> <a href="#nerf"><img border="0" id="seat0" src="images/available.gif"></a> </div> </body> What im trying to do change my function so that instead of it being hard coded for the id "imgSeat" i can use the id passed through the parameter "img" instead. However I seem to be banging my head against the wall. I've tried using the following Code: document.getElementById(img).src = "images/available.gif"; //no error, just does nothing //where img is "0" instead of "seat0" document.seat[img].src = "images/available.gif"; //error: document.seat is undefined Would be extremely greatful if someone should push me in the right direction or show me what im doing wrong. I am new to javascript and would like to search for the element with id but the element id are changing if i use different navigation in that web page example: C21_W68_V69_notes_struct.text changes to C24_W78_V79_notes_struct.text or any other name next time hence i would like to search that element using a pattern like notes_struct.text as there exist only one element ending with this pattern. I am using old version IE and would like to use javascript only. Kindly help. I am very new to javascript(and these forums) and I am teaching my self to use the canvas element. I am trying to draw an image to the canvas but nothing is appearing. And I am getting no error in the chrome console. Can anyone see why? Code:
function RPGanimation(options)
{
this.initcanvas(options);
this.initbackground(options);
};
RPGanimation.prototype = {
initbackground: function(options){
this.background = new Image();
this.background.src = options.backsource;
this.background.onload = this.drawbackground();
},
initcanvas:function(options){
this.canvas = document.getElementById(options.canvasid);
this.context = this.canvas.getContext('2d');
this.dimensions = {width:this.canvas.width,height:this.canvas.height};
},
drawbackground:function(){
//document.write('<IMG SRC="Chrysanthemum.jpg">');
this.context.drawImage(this.background,0,0,this.dimensions.width,this.dimensions.height);
}
};
I create the object in a webpage with the canvas element created just before that script tag... I started using the Google News Web Element on my website. The website for Google News Web Element is: http://www.google.com/webelements/#!/news I want the links to open in a new window, which cannot be done with the iframe version. Their website only allows me to generate an iframe. I was told that this can be done by using the javascript version, but I have not been able to figure it out. This is their link to the documentation: http://code.google.com/apis/newssearch/newsshow/ I know very little about javascript, and have been trying to get it to work but have been unsuccessful. I want to use the Medium Rectangle size and I want the only topic to be "Swainsboro". The only modification that I want to make is for the links to open in a new window. If anyone can help me do this, it would be appreciated. This is the iframe data that was generated by the wizard: Code: <iframe frameborder=0 marginwidth=0 marginheight=0 border=0 style="border:0;margin:0;width:300px;height:250px;" src="http://www.google.com/uds/modules/elements/newsshow/iframe.html?rsz=large&format=300x250&ned=us&hl=en&q=Swainsboro&element=true" scrolling="no" allowtransparency="true"></iframe> i want to add a tooltip----click to copy to the Copy To Clipboard... box like this site(http://www.retailmenot.com). the yellow part with a Scissor. but when i used jquery to add it. it doesn't work. why? i test it on this site: Quote: http://bowser.effectgames.com/~jhuck...rd/test10.html Code: $(document).ready(function(){
$("#d_clip_container").hover(
function () {
$(this).append($('<span class="tip">click to copy</span>'));
},
function () {
$(this).find("span:last").remove();
});
})
i have added the jquery library. The reason of the tooltip can't work maybe the copied text is wrapped by the flash, but this site (retailmenot.com) can do. i don't know why? how to do it? thank you. |
