But when I request, it gives me this in the url: MajorCat%3AShoes That won't work, the search application on the backend doesn't filter properly because of the "%3A" instead of ":". When I manually pass in via the url: MajorCat: Shoes (at the end of the query) it works. So, that ":" is getting encoded. How do I get that IN the hash and make sure the request is unencoded when it goes out?
I have been looking at Prototype.js quite a bit lately as I need to create a very small library of similar functionality to a subset of Prototype.js. This is for use with Ruby on Rails.
About Prototype.js Rob G wrote:
1. It modifies the protoype of some built-in objects so that using say, for..in with an array object produces unexpected results.
I can see that modifying the prototypes of Object or Array could break other JavaScript libraries that depend on for..in. Prototype.js also adds functions to the prototype of Element. How bad is that? (I notice that in Flanagan's JavaScript 4th edition he mentions that you can modify the prototypes of built in objects however there is no mention of the dangers involved.)
I then thought I could use an instance of Element as the prototype of a MyElement constructor but that option has been squashed in the past as being not cross browser.
Assuming I shouldn't be playing with the prototypes of built-in JavaScript objects I can see a couple options that might still be available. Code:
In the spirit of the season, I wanted to make it snow on my website. So I began digging. Eventually I ended up with a script that moved an image element down the page in a snowflake-like manner. The problem with it was it was dependant on an img element for every flake - simply no poor programming when using an Object Oriented programming language.So I decided I wanted to extend (in Java-speak; most of my programming background is in Java) the in-built Image object. The new object's src variable will lead to an image of the type of flake it is. (I want to be able to have more variance in images than a simple dot.) The new object will have a function that will allow it to move.A separate,unrelated function will control when each flakes move.
I did some more research and read about prototyping on JavaScript Kit and here (http://mckoss.com/jscript/object.htm), but I still cant seem to get this to work. JS Lint says it's bug-free, but Firefox says "move()" is an invalid function. I am presuming the problem lies in my inability to fully grasp how to extend objects in JavaScript.
i'm new to ajax. simple request no problem - but it seems when I set the response handler function, I can only pass the function name and not give parameters, so I have a problem when starting e.g. 5 ajax requests parallele. how to do that correctly? for one case, where I used *different* resp. handlers, I solved the problem by global variables - but now I have a loop of e.g. 20 calls to the *same* r.handler and I don*t know how to tell the function *which* request of the 20 to use. I expect the solution to be simple but how..
I have an Ajax script which works fine in IE, Opera, etc, but not in FF 3.6. It appears the data sent is not recognized. My debug alert to display a simple variable sent is blank. In other browsers it displays fine. I'm developing on my PC so shouldn't have the cross domain issue, I don't think?
Here is the code function ajaxRequest() { $.ajax({ type: "POST", url: 'WTE_HTTP_Submit.cfm',
This could appear under Ajax, for example, you could have multiple objects that make a singular ajax call (say an RPC-like request) and you need to update the object that made the call during the callback with the result, but it doesn't have to be. The particular problem I'm thinking about happens to be ajax, particularly with multiple objects accessing the same ajax request (meaning I can't use a global or temporary variable).
One way that seems like it would work (just thinking about it in my head), is to create a hash, and to pass the key through the request, store the key in the response, and pick it up on the callback side. Then remove the item from the hash when done.
JQuery seems to be giving an error when trying to pass an alphanumeric parameter like so:
[Code]...
when the above method is called, the error callback is called. However when I change the eventID parameter to a purely numeric value, it works fine and the success callback is called. I would like to pass an alphanumeric value to a server method and this doesnt seem to work.
For some reason I can't seem to print out the post parameters sent through out my login php script using ajax.. according to ajax (*responseText) the parameters are getting passed.. so.. it got me there..

I want - when the page load in result div will apper "Hello bla bla". It works for me if I dont use parameter(aka data: "{ }" and HelloToYou dont accept parameters)
I like the looks of the validation engine plugin, but I can't figure out one thing... For a particular form field, I need to use an Ajax service to validate the data. I have to pass the value of the text input, of course, but I also need to pass a couple of other key=value pairs along with it. In the file with the selectors there's the option to add extraData (like extraData="name=eric") but I need to set these parameters based on some dynamic info.Is there a way to pass extra information to the ajax service?
Can someone give me some pointers on how I can read one or more arguements from a url, using js?
Why? I'm working on a LAMP based project and when a user successfully registers, the header redirects to the login screen - I'd like to check for the value of register, if read from:
I am pretty rusty with javascript and I am trying to make a webpage that will basically act as a wrapper from one webpage to another. What I mean by this is that I will hit this page like: webpage.htm?Param1=... and I will take the passed params and post them to another page. I have the post part working, but I was just wondering how I can use just Javascript and read those values passed to this webpage. Is this even possible?
I found this little script for extracting parameters from a url but wondered what the shortest and most efficient way to do it would be, like the following or via regexp?
function getParameter(paramName) { var currentUrl = window.location.search var strBegin = currentUrl.indexOf(paramName) + (paramName.length+1) var strEnd = currentUrl.indexOf("&",strBegin)
if (strEnd==-1) strEnd = currentUrl.length return currentUrl.substring(strBegin,strEnd) }
I have an onclick function that pops a new window (nothing fancy) the problem is that whenever I want to return to the page where I popped the new window from I find that it is reloaded and has taken me to the fist line of the page. What parameter (or anything else for that matter) can I add in order to pop up a new window and still be in the same place when I return to the previous page?
I need to know a way to get/set URL parameters with jQuery.
Here is the flow between pages im having:
What i want to have is:
Each page offers a choice to user and must add the choice in url. Actually im using forms with submit buttons to do it but i dont know how to keep parameters from previous page in the current page.
I need to get which all are the parameter in the current url[URL]...Since my parameters changes every time, I need to get the parameters (not values of parameters)
I want to pass parameters thru URL. I know how to pass. I am finding problem in reading the parameters. here is the [URL]. how to to read these parameters from URL using java script?
i m trying to implement captcha in my site.i m using recaptcha. To check the captcha i need to request url like: [URL] and then i need to check response from url if it is true or false i dont know how to request response from url
