I'm trying to use jquery with php by sending out calls and getting values returned, but I need to store them on a variable, but whenever I do that nothing shows this is the code I have now and is not working
$("document").ready(function(){
var cal = $.get("date.php",
function(data){
I have been trying to grasp the whole 'Pass By Value/Reference' thing for a few hours now. From what i can make out:
Passing by value will make a copy of the value, pass it as a function argument and the function will store the changes, the original value is not affected. So for example:
JavaScript Code:
var cost = 145;var postage = .3;var a = function() {return cost + postage;} //Using an Anonymous function for this
If you was then to pass the value of 'a' to a function argument it would copy and not change the original value.
If you pass by reference it will change the original value. When you pass a reference to a value through a series of different functions and the value is constantly being changed the change happens on the original value and can be seen outside the function.
The problem is i cannot think of how or why this would be used. I havn't got to develop many large applications so im trying to think of a few situations when passing by reference would be used.
I have an array list that I create in the page.load event. I'm creating it here, because the array list is built from the data in a database based on the value of the querysting.
I want to use this array list as the list of photos in a slideshow. What do I do o that jquery can get access to the array?
I have a page with dozens of anchored links. When you click on the link, the appropriate div becomes visible. Each div contains an image. Because each DIV has a large image associated with it, it takes entirely too long for the page to load. I would like to set the IMG SRC inside of the div when they click. Each anchor href is the exact same name as the image to be loaded - so #dali would contain dali.jpg. How dow I pass the HREF minus the hash mark (#)? This is as far as I've gotten:
$("a").click(function() {
var whichDiv = $(this).attr("href");
$(whichDiv).attr("src", "images/art/" + whichDiv + ".jpg");
});

I don't understand how to pass the currentId variable to the .addClass method as the above code does not work. If I replace currentId with 'id_1" it works. I also verified that currentId has actually an id value like this:
document.write(currentId);
but I'm really missing how to pass that variable.

I have successfully set up & tested the use of the LocalScroll plugin on my project (which also uses the ScrollTo plugin). Having just started using jQuery today, I was trying to figure out how you would pass a value entered into a search box through to jQuery.
The LocalScroll plugin scrolls using anchor tags that reference the ID of the element. So clicking the "This is some text" link below... code...
What I am wanting to do is provide a search box so that when the user enters a value (i.e., myID) and clicks the Search button, this value is passed to LocalScroll as the ID value to scroll to. It would be like clicking the link "This is some text" above. Is this possible?

pass a JavaScript value to PHP.It's based around jQuizMe script. I'm trying to pass the JavaScript value to a new page, so I can do what I like with it in PHP.quizInfo.numOfRight is the JavaScript array of the value of the persons final quiz score is stored in.
PHP Code:
if( quizInfo.hasQuit ){ var ScoreForPHP = quizInfo.numOfRight; WHAT NEXT? }
I'm thinking that perhaps we will need to redirect the person to another page when quizInfo.hasQuit is ran, then storing the JavaScript value into a PHP Array.

I sort of ajax a data into a div id, but I was wondering, is it possible to pass the items in the div element into a php variable?
View 3 Replies View RelatedI have one page which is the server processing where the link is and the other page which shows the user page.On clicking on the link I manage to make a panel (slide toggle kind) be displayed alright. But I still need that on clicking on that link a value is passed. I think I have to write a couple of lines more in the Ajax snippet but dont know how exactly. I have seen a similar question but havent been able to translate it to my specific case.[code]Well, somewhere in the middle or maybe in another Ajax snippet I should put that $get and this should be returned so that a SQL query can take that value and work with it.

I got a problem with passing dynamic DIV ID. I was doing some a php page which retrieved data from database and put into according DIV tag like this:
<DIV id="variabl1">msg1</td>;
Since there were tens of records in the table in database, the result would become:
<DIV id="variabl1">msg1</td>;
<DIV id="variabl2">msg2</td>;
<DIV id="variabl100">msg100</td>;

How can i pass values of a form to jquery pop up by clicking submit button?

I have pagination enabled in my site using jquery. here is the pager code i am using to display my page numbers, next and previous buttons etc. Everything works except that when I click on a product to view the product details and hit a back button i have in that page to come back where one came from, it always takes back me to the first page.
What i mean is if i view a product from page 2 instead of taking back to page 2 it always takes back to page 1.
I am wondering if in passing the current page number to my back button, so it remembers the page where it came.
click on any image and hit the back button, it always goes back to page 1.

I am attempting to hack a jQuery extension that does an ajax style form submit. The final result is an image uploader that can run inline. The script is fairly simple - it creates an iframe with a new form, and copies over a form element (the file name), and submits the form. Plus error handling and the like.
The problem is that I need to use from within MVC, and so I need more form values, like the ID of the item I am working on. It would be easy to add another configuration setting for an additional form element to copy over, but I really want to have the ability to pass a jQuery selector in and use that to specify the form elements to copy. Is this possible?
