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.
How can I have global variables and global arrays whose value(s) can be modified and accessed by all the Javascript functions in my HTML document as well as by the HTML code?
use this kind of syntax in an open source plugin.#varableName = someMethod(); that someMethod return an object instance.Then I can access that object outside that plugin. Is this a standard javascript global variable or some jQuery feature?
I've googled this and found a few different explanations that (as a PHP developer) are making absolutely no sense to me. I'm a total beginner with Javascript (not just jQuery) so a little help would go a long
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 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'm new to jQuery but pretty familiar with JavaScript. I would like to convert the code below to a function that can be used like "$("#member-feedback li ").rotateElements()". I've looked at some examples, but I'm not sure where to start.
I'm trying to define a selector as a global variable and it keeps coming back undefined. I tried creating a namespace for it but had no luck. I would like to be able to reference the sliderRange, currentMin, currentMax globally.
I cannot findout how I can write to global variables in a a JQUERY function. <script type="text/javascript"> function checkusername (username ) { $.post("[URL]", { action: 5, username: username }, function(xml) { result = $("apot", xml).text(); //<-- this variable is not global... why ?? message = $("message", xml).text(); //<-- this variable is not global... why ?? alert(message); //<--here variables are shown ok alert(result); }); alert(message); //<--here variable is NULL !! alert(result); //<--here variable is NULL !! } </sctipt>
I have a global stylesheet. In that stylesheet I have:
I need to turn off the top:-9px, because IE7 renders my menu wrong with it there. I have a stylesheet for IE that overrides global which I set to: .index .left #search_accordion .flyout {position: absolute; top: 0px;} or .index .left #search_accordion .flyout {position: absolute;}.
When I make top:0px, I get the wrong positioning. When I leave don't include the selector "top" then the browser pulls the value from the global stylesheet (top:-9px). The solution is I need take "top" out completely.
I'm having trouble letting functions I defined in jquery read javascript global variables I defined elsewhere.. for example I have a function defined within my jquery
$(document).ready(function(){ function performTabSlide() { // do something with currentPosition;
i have this problem in passing values to a variable in a jquery function.
i have a js variable that accepts a certain value and then i want to pass this variable in the jquery function.
For example, this is my script: var autoScrollBool = "true" var autoScroolInt = "10" (seconds) stepcarousel.setup({
[Code].....
i want to replace the value of autostep: {enable:true to enable: utoScrollBool(the variable i created) , when i tried to assign it as is, its not working.
In this function, I'm trying to set the value of isValid with the results of $.post:
[Code]...
Unfortunately, isValid never changes from the initial "true". I know that $.post is working correctly because #msg_code reflects the corresponding message.
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?
