JQuery :: How To Store A Bound Key For Later Retreival
Jul 22, 2009
I though I'd give these forums a shot. I'm having trouble figuring out how to accomplish something and was hoping someone could help. I currently have the 'enter' key bound to a submit event on several on my pages, as follows.$(document).bind('keydown','return',function(){ $("#searchSearchButton").click(); });It works well, with one problem. I've written over the alert function with my own custom alert. When the alert pops up, I try to hit 'enter' to close the alert and nothing happens because the enter key is bound to something else.
I've found that if I unbind the enter key and rebind it to close my alert box, that works fine, but I can't figure out how, after the alert box is closed, to rebind it to the previous value. I'd have to grab the existing bind value before rebinding it to close the alert box, then replace that value afterward, but I have no clue how to grab the bind key's value.
i got an ajax script that appends a new form as the user perform some actions.then i bind them to the 'submit' event. the problem is that the existing forms get bound again and now submit twice, while the newly appended forms submit once.
is there a function to check if that form has already been bound, so that i won't bind it again? in the docs there's a unbind(). But will it slow down if i append more and more forms?
I'm trying to implement a validation in my form, but that should not be bound to an specific field. in fact, I have three input type=text, and I need at least one of them to be filled (like a conditional 'required').
I've come across an issue where I've got a dynamically created popup class that despite appearing to be bound according to Visual Event does not fire on clicking the closebutton attached to it. I'm not getting any errors in firebug and by setting breakpoints I've verified we are not reaching the code to execute. Ruling out the usual suspects such as obvious spelling mistakes/ swapping out jquery versions 1.3/1.4/1.5 doesn't make any difference.where else I can look?Here is the original function:
$this.find(".close").live('click', function() { var $this = $(this); $this.parents("." + sets.popupClass).remove();
I have this boiled down to the following code: [URL]. I have two text inputs in a form, and a keydown handler to catch the arrow keys. When the focus is lost on an input, it is supposed to call the submit handler on the form. When I use the tab key, it works as expected, and calls my submit handler. However, when I use the arrow keys, it submits the form and goes to the action url, not running the alert in my custom submit handler. It's as if it either loses the bound submit handler or it calls a new default one or something.
THE QUESTION: How do I get a reference to my Object when processing an event handler bound to an html element ?
CONTEXT: Sorry if it is a bit long.
I am developing a JS calendar tool. One of the requirements is that the calendar will need to display a varying number of months (1..3) depending on the calling page. Imagine 1, 2 or 3 calendar pages side by side as required.
I have built a grid object that will contain one month's dates with the day names at the top. The calendar object inherits the grid object as an array of "calendar pages" - one grid per month and the calendar provides the content for each grid. I will use the grid object for another completely different object later and so I want to use good OOP encapsulation. The grid is a table generated on the fly and is "dumb" as far as what it is used for.
I have attached an onlick event to each cell of the grid. Using OOP priciples I want the calling program (the calendar object in this case) to provide a function to handle the click and the grid object will provide to the calendar the row and column of that cell as well as the grid number (so the calendar can work out which date was clicked since it knows what the data means and the grid doesnt). Code:
I then loop thru the array to assign the text and bind the click event after having created the buttons with IDs of "button_<index>".
for( var index in buttons ) { $("#button_"+index).html ( buttons[index].text ) .click( function() { clickButton( buttons[index].action ) } ); }
The text appears correctly in the button, but every button defined only fires the list bound click, in this example the action equal to'2'whether I push "Button 1" or "Button 2".My actual case has four buttons, all firing the event for the fourth button.I've tried not chaining the .click(), going thru the loop twice once for the .html and once for the .click, neither of which made a difference. If I hard code each button .click, it works fine.
I am calling a PHP script and trying to store the results to a Global Variable for use in later functions. But It doesn't seem to be saving the results to the variable. I have found, that within the ajax success call it will display the proper information. Outside of the AJAX success (whether in the function or outside of it) the variable is listed as undeclared.
I am trying to use jQuery AJAX. What my requirement is, i wish to load user names from DB in dataset, convert it to JSON format and store it in memory or using jQuery data for use while a user is browsing my site, i.e for a session. This way I can use autocomplete or my own code to display data to user.
My table is a data table, and I'm contemplating using it as the data store as well, rather than keep a js array of data separately. The cell values are retrieved by ajax, then inserted into the table. I'm thinking that the duplication of data (once in the js array, once in the table) is likely to lead to strange results somewhere along the line, where the two data sets get out of synch. It seems to me that jquery makes using a table in this way rather simple (I refer to the jquery selectors in particular). The table includes some editable-in-place columns.
If any such edits, and user presses a Save button above the table, the save function finds the edited fields and sends an appropriate ajax call, then refreshes the table with the outcome (eg it worked, so new values remain shown, it didn't work, revert, or something like that, it's not too important here). Hence the need to maintain some 'awareness' of the values in the cells. I'm content with using attributes as needed to support this (e.g., to be able to revert to original value, to mark cells that have been edited). Table may contain up to 500 rows, ten columns. How it compares with keeping the data in a js array?
I wanted to define additional attribute to a tag to manage information. I realized that XHTML might not like it and discovered the data(name,value) function. I was wondering how I could retrieve all tags e.g. "div" that have that data variable set.
I have created the application in PHP and JQuery of display locations on google map.THere are few images in divs after clicking on it there are 3 ajax requests are called in following order 1: to display video from youtube2: to display description from database.3: to display locations on map. After clicking on images in div, result is displayed in following order.1: to display description from database. (It is displayed within 1 sec) 2: to display locations on map. (It is displayed within 2 sec)3: to display video from youtube. (It is displayed within 2 sec to 3 sec) As map and youtube video are not located on local server, so that those are taking time to display.Is there any way to display all above 3 output when all data will receive from their servers?
I'm using this bit of jQ to add a class to two different elements based on the class of another (parent/grandparent, etc) element.
First, when there's no class at all in <div id="main-content">, the 'active' class is added to *all* the #nav-primary LIs, and also to *all* the #aux-left DIVs; how can I modify this so that in the absence of any class on #main-content, do nothing?
Second, how can I target only the first or second of multiple classes to store in the 'containerClass' variable, e.g., <div id="main-content" class="apples bananas">?
am very new to JQuery. I need to create a form, which will take username and email id and store it in a text/csv file.I do not want to use PHP/ASP.I am familiar with Java script.Is there a way I could do this?
I am working on a cognos requirement, where we have implemented java script code. The thing is, At the run time, when we give a serial number in a text box and press finish button. The serial number which we gave has to be stored in the text box. Later when the user clicks the "Clear" Button. The serial number text box has to prompt for fresh value.
