Getting Value Of A Link With Dynamic Creation?
Mar 7, 2011
I'm creating some links with PHP and here is the code for that:
Code:
<br><a id="add_to_cart" href="add_to_cart.php?pic_id=<?php echo $resultsetnewpic['pic_id']; ?>" class="under_pic_cart">Add to Shopping Cart</a>
There is a while loop to keep adding them but wanted to keep it simple. So right now there are three links that get created. I'm trying to find out the value of these links so I can add things to a shopping cart for the user. I have the following jquery to do this:
Code:
$(function() {
$(".under_pic_cart").click(function(){
alert("it gets here");
[Code]....
This part works fine. However how can I get the href value of this and then once I have it basically split it after the = sign to get the value I'm really looking for?

I'm building a DIV dynamically and putting a P into it like so:
var oDiv = document.createElement("DIV");
var oP = document.createElement("P");
oP.style.backgroundColor = "green";
oP.appendChild( document.createTextNode("some sample text") );
oDiv.appendChild(oP);
oDiv.style.position = "absolute";
oDiv.style.left = "100px";
oDiv.style.top = "100px";
oDiv.style.width = "200px";
oDiv.style.height = "150px";
oDiv.style.backgroundColor = "blue";
document.body.appendChild(oDiv);
The problem is that FF doesn't put the P in the top left corner of the
DIV. Rather it seem to push it down by a line height. Is there some
white space sneaking into the DIV? How do I get the P right into the top
left corner?

can anybody tell me how you can create a new stylesheet inside a
(X)HTML page with JavaScript and Firefox, if the stylesheet is only
available as a variable value, like:
var CSSStyle = "rect {fill: lightgrey;}
circle {fill: red;}
polyline {fill: none; stroke: red; stroke-width: 0.3;}
text {font-size: 2.5px;}
text.text-x-axis {text-anchor: middle;}
text.text-y-axis {text-anchor: end;}"
So far, the only workaround I found, was to link an empty stylesheet to
the page
<link rel="stylesheet" type="text/css" href="./empty.css"/>
and then use the insertRule method on this stylesheet for every single
rule from the variable (indexOf('}') / substring()).

I have reason to want to be able to change a Firefox stylesheet rule dynamically. I have found, doing google searches, sites which tell you how to create stylesheets dynamically or just add and delete rules, but none of these pages procedures have worked in my Firefox. Some have worked in Internet Explorer. Most have claimed to be cross browser. An example of one which I had high hopes would work can be found at this link.. The code they give you near the bottom of that page is posted below with the original background color changed to red and some text to see the background color put in the body of the page. In other words I pretty much just pasted the code found their in the head portion of my HTML page.
Attempting to troubleshoot why this code is not working if I use the old alert message method and put an alert message between the lines "var mysheet=document.styleSheets[0]" and the line "var totalrules=mysheet.cssRules? mysheet.cssRules.length : mysheet.rules.length" the mysheet variable region out as being "object CSSStyleSheet", however if I use the newer step through method with firebug it reads undefined. So I am totally baffled. Code:

I have a small number of functions on an object and for every function I wish to make a different function that calls the original where the this can be passed as a parameter. I am making a library and this is a convenience method for people who don't know about call/apply.
Currently (one of) my function looks like this:
function _find(){
return find.apply(arguments[0],Array.prototype.slice.call(arguments,1));
}
However since my functions are in a object I was wondering if I could make a new array dynamically?
var func = {'find':find}, func_new={}; //this is just an example I don't have this part in my code
for(var attr in func)
func_new[attr] = Function('return '+attr+'.apply(arguments[0],Array.prototype.slice.call(arguments,1));');

I have a task to create tables dynamically, using the javascript DOM.
The current method uses a 1px x 1px IFRAME to loop through some data
generation stuff, and then call JS functions in the parent window to
generate the tables.
The basic idea is to add a table tag, with a thead and tbody, on the
main parent page, that has display:none set. This then becomes
display:block when there are rows to show. The rows themselves are
added directly to the visible tbody element using appendChild(). When
the results need to be refreshed, the tbody elements are removed, and
then added again.
This works well in most browsers, including Opera. However, Mac IE
always freezes when trying to generate the table, even for the first
time.
I have several different versions, and they all generate the same
issue. The tables I am creating are quite complex: multiple cells,
colspans, images, nested tables, roll over colours, styles etc. At
first, I believed it was an issue with creating images dynamically,
however it now seems that is not the case.
I have also tried creating the table and tbody tags using the DOM and
appending them to a div, but with no luck. I have also tried creating
the tables using a hidden object and then copying the innerHTML / nodes
across to the visible one. The various versions I have cover most
bases:
* using innerHTML to add content to the cells
* using the javascript DOM to create all elements and append them
* using a mixture of the both
If anybody has any feedback or suggestions then it would be really
appreciated, particularly related to the following:
* From your experience, is this realistically possible?
* Is the problem I'm experiencing related to the complexity or size
of the table I am trying to generate? If the table is simple text only,
with 2 or 3 columns and rows, then it does work.
* What is the best method to dynamically create tables and cell
content across browsers, and in Mac IE?
* Is the problem image related? Does anyone have experience of
creating images dynamically in tables in Mac IE? Do you use "new
image()" or createElement()? (using the small table sample, this was
possible using both methods, and also innerHTML on a cell).

I'm dynamically creating a table. I create the <tr>s with five <td>s. I then remove the third <td> and would like to add the cell variable where I removed the td. The creation of the table works, the removal of the td works, now how do I add the cell var where I removed the td? Example here: [URL]
Code JavaScript:
function CreateTable() {
var array = ["one", "two", "three", "four", "five", "six", "seven", "eight", "one", "one", "three", "seven"];
var listItems = "";
var tbody = $('.tbody');
var cell = $('<td>', {
className: 'open',
html: 'Open'
});
$.each(array, function(index, val) {
var row = jQuery('<tr></tr>')
.append('<td>' + index + ' - ' + val + '</td><td> open </td><td> open </td><td> open </td><td> open </td>');
$('td:eq(2)', row).css('background-color', '#eee');
$('td:eq(2)', row).remove();
row = row.add(cell);
row.appendTo(tbody);
});
}

I have a form that allows for dynamic field creation. Basically, you click the + button, and an addition row of fields (2 text fields) are created. The area that is dynamically created is wrapped by a <div id>, within which is, and this might be bad practice so please feel free to mock me , another few nested div id's. It looks something like this:
Code:
Each time you hit the +, it creates a new div id beneath the "Adds" id.
What I'd like to do is see the values of the id's "row_fqdn" and "row_ip". Is there a quick way to access the values of nested id's?
I found a workaround but it seems pretty messy and drawn out, something like this:
Code:
I'm looking for a way to do something like this:

A while back, I an working on dynamic form creation. I wanted a user to be able to enter into a text field how many designs he or she would like, then, based on that number, be provided with a pair of text boxes that asked 1) name of design 2) quantity of that particular design. I received this cool way of doing it by user thraddash:
<head>
<script type="text/javascript">
function BuildFormFields($amount){
var
$container = document.getElementById('FormFields'),
$item, $field, $i;
$container.innerHTML = '';
for ($i = 0; $i < $amount; $i++) {
$item = document.createElement('div');
$item.style.margin = '3px';
$field = document.createElement('span');
$field.innerHTML = 'Name of Design';
$field.style.marginRight = '10px';
$item.appendChild($field); .....
As a followup, I wonder how to control in a table where each of these text boxes will appear.

I'm trying to create a webpage where users can click on a dynamically generated set of questions:
<?php do { ?>
<p><?php echo $row_rsQuestions['question_text']; ?><?php echo $row_rsQuestions['question_type']; ?></p>
<?php } while ($row_rsQuestions = mysql_fetch_assoc($rsQuestions)); ?>
and by clicking on a particular question, there will be an update for their particular listing of personal questions in a MySql database. I know how to create the database update part, but I think that I would need to javascript to:
1) tell my page that it's time to update (i.e. add a particular question as soon as they click it)
2) pass along the correct variable to the database update portion of the page.

We would like to create a new website and have that do some dynamic things based on login id. First all we would like to send you do a different home page based on this information, it might be one of several companies. This may also be tied to what URL you clicked but not necessarily. The second thing we would like to do is display only the products that you are eligible for based on your login information. We would like to use images as a link here and if you can sell one product you get one image or maybe bypass and go directly to that section, but if you can sell two or more then those images as links show up as available.
The final thing we want to do is to populate the top 3 or so items you perform on the site as quick links. After all that, are there tools or items I should study to accomplish this task? I'm not sure if I need to mix in some sort of third party analytical tool with the asp.net site or what. The only other thing that I think we can do with ajax is have them say enter a a vehicle identification number and without looking like a screen reload use ajax to show the additional information such as year make and model that are decoded from the vin, but I'm just starting to look into this.

I have to do a project, the requirements i have got are, same link on multiple pages should lead to a single page on client's site, but the page should be different for each link clicked.
What i understand from this is, we will send parameters with each link to a JS or php file and then generate a dynamic page each time, but i am not clear how many files we need to call and what will be the sequence. I want to implement this in JS and php.
how to implement it with JS and PHP if we send parameters with the url and if we don't send any parameters.

I want to make a dynamic 4 drop down menus with AJAX and PHP/mySQL, like this:
Category->dynamic subCategory
County->dynamic cityCounty
Is there any good tutorial that can teach me how to do this? I managed
to have that Category dynamicly loads subCategory and that County
dynamicly loads cityCounty but I ran into a problem when I already
picked subCategory and than went on to pick a County, because of the
reload.this function in javascript my subCategory gets lost. Can anyone
point me in right direction?

There's a feature I want to implement, but don't really know how to code. The intention is to use jQuery to convert words with a certain class attribute into Wikipedia links.
An example to make things clearer:
PLAIN TEXT: There is a <span class="wiki">penguin</span> there.
EXPECTED RESULT: There is a <a href [url] there.
Hence the code would have to grab the string of words inside the tag and place them inside a href with the first part of the link already attached to it. Doesn't seem too complicated, but I wasn't able to do it.
I have been trying to use the code below (created by Patrick Haney and improved by enraged) as a basis, but no deal. This code subistitutes words for code, but it searches for specific words.
If anybody knows a script like that, modify the code below,

I know that it is possible to create map via javascript, which has some spots used like links.
I have 3 images:
background, house and man.
Also 3 php variables:
$man = 'yes';
$background = 'yes';
$house = 'no';
What I need is to make javascript map which would show background(yes) and man (yes). House must be invisible, because I have NO.
The problem, that man must appear to 21px width 100px height and be active as a link.
If you haven't understood what I want - ask.
Now I will try to explain this with example.
You have a map with countries. But map is like image and you can't do anything. If variable with country gets value "yes" - the country become active on the map and you can push on it.

I'm working on a script for Hulu that will present the user with some options, then automatically sort their queue depending on those options (a blessing for someone like me with 450+ entries). The sequence is as such:Read and store all entry rowsPresent user with a form to assign shows to categoriesPresent user with a form to assign weights to categories (so something can show up more or less often in a "block") as well as options for how to sort entriesSort previous row listings based on user inputDecide the order of shows and change the values of their respective "Order" boxesI've gotten it to work up until this last part. I'm creating the dialogue boxes using proper DOM input (at least, I believe so), but for some reason I can't use getElementById() or getElementsByName(). I can use getElementsByClassName() and getElementsByTagName(). When trying to use the first two, I'm just told that it isn't a function.
Here's the code section itself, the problem line is Line 3:
Javascript Code:
This is inside an onclick event; finalBox is declared outside of that handler. I'm able to use finalBox.getElementsByClassName in the same function about 20 lines up. For reference, here's where I create the elements I'm trying to find:
Javascript Code:
CustRow is a function that helps me shorten the code of adding a cell to a row (with addCell()); it creates a row element and attaches it to the given table element.
That first piece of code is the only place where I use getElementById. My main thought is that I'm doing the ID wrong and, for some reason, it's not registering with the DOM (though that doesn't explain why getElementById() still fails instead of returning null/undefined). Also, while I hope to eventually make this a FireFox add-on, I'm executing all of this through the FireBug console, so I don't know if that would affect it or not.
Any insights? I can change it to use getElementsByClassName (and it appears to work), but this is really frustrating me and I'd prefer not to use a messy work-around. (Actually, getElementsByName would be best, but I thought that getElementById would at least work.)
