Ajax :: Adding An Error To All JQuery Post() Functions?
Jul 25, 2011
Our app handles all users information via AJAX using jQuery. We return data.success or data.error depending on if it the API works or not. We also run the jQuery error() function on each post() just in case there is an actual problem reaching the server. It's getting tedious having the same thing for all of them.Here's a simplified example:
I haven't seen much mention of this on the web, and only recently discovered it works.... not sure if this is somehow bad practice or just a lesser known trick, but lately I've been chaining .ready() at the end of .html() when I want to bind events to new ajax data. I presume it's much more efficient than live(), and avoids racing issues. E.G.: $.ajax({ type: 'POST', url: 'myPage.html', success: function(c){ $(".response").html(c).ready(function() { bindNewEvent(".response a"); }); }); function bindNewEvent(o) { $(o).click(funciton() { ...etc... }); }; There's infinite docs about using .ready() to process the document, but not returning HTML. Passing the above along should anyone find it useful or have insight onto why it's seemingly not mentioned elsewhere.
I have a table that i load into the document via ajax. the table shows a list of times. every row has a button that when clicked should call another AJAX function. However when clicking the link nothing happens. If I put a link in the original document myself and ask it to do this, it works fine, but becuse this is generated code, this option will not do.
I'm adding is a flag to indicate that a post was sent via ajax. Is there a better way to do this so that I don't have to add the flag every time an ajax form is posted?
I have an error when I POST to a page. Whatever monetary choice of donation that is made, the POST does not work to send the values to the next page and the default value of $20.00 is registered.
After looking at my code for a day I dont see the errorL

Am calling Webservice in one ajax post, In the success funtion am calling another another method in same webservice through another ajax post method. First ajax post is getting called and returning the string from the webservice method but the inner ajax call is not getting called. I have placed the code here.
I have a basic HTML form with a button that submits the form via jQuery's $.post to a processor. That processor returns the identical form, including any errors below any of the elements e.g. input, textarea, etc. The response also has a new submit button to submit the form once more, however, because I'm retrieving a giant string with HTML elements and because jQuery already loaded, that new submit button doesn't do anything. How can I parse jQuery's response for that button and assign a handler so that when the button is pushed, it submits the form again?
I've been trying to figure out how to echo back error messages from a PHP edit page, for example. Say if I am editing a grid and sending that info with json to a php page to update a database, if there is a validation or other problem, how do I echo that back on the page with the jquery? Do I put that in a div container too for best practice?
im getting this error when on my script that rebinds functions and recreates dialogs, what could be the problem?I am using jQuery 1.5.1.min & jQuery UI 1.8.11
[Exception... "'Syntax error, unrecognized expression: "' when calling method: [nsIDOMEventListener::handleEvent]" nsresult: "0x8057001e (NS_ERROR_XPC_JS_THREW_STRING)" location: "<unknown>" data: no] Line 0
:confused: when user clicks submit first it should check to see if a name from the dropdown has been selected then it should check to make sure all radio buttons were selected. code to check if a name was selected in the drop down.
Might there be a way to add a set of Javascript functions to a display page's existing set of Javascript functions on the fly without reloading the display page, and if so, how?
A couple of approaches I have tried, but without success are:
- A) For an embedded "retriever" IFrame in the display page to retrieve a set of JS functions from the server and then on its "onload" transfer (by innerHTML transference) that set of functions into the parent display page.
- B) Similiar to "A" but to use regular old browser frames - one being the "retriever" and one being the display page.
- C) Using a JS function in the display page to make a http request for a supplementary .js file(s).
Please note: the goal is to retrieve *only* an additional set of Javascript functions from the server, and then add them to an "original" set of functions already loaded into the browser. Meaning, NOT - say - for an IFrame to download from the server *both* the additional set and again the "original" set, which the parent display page could then run directly from the IFrame.
After "A", "B", and "C", I'm at a loss for further ideas.
Is there a way to make 2 functions load at the same time using window.onload? I have to seperate functions which rotate images, then another that rotates text.Functions:showQuote()iAnimate()
within this page that has been created, there is an AJAX tree folder which calls another page to be loaded into a DIV by AJAX again. Code:
[Code]...
I don't know why it doesn't work because the page has been loaded with the JS file, but as soon as the link is added afterwards it doesn't work. I take it this is because it doesn't know where to find the JS, but how can I overcome this?
I posted this problem in the old mailing list, but I thought Id try here with a larger set of eyes.
My issue seems to concern webkit browsers. I am sending information from a form with a jQuery click function. I am loading the response from one form that is a DIV called rightContent to the same DIV and passing the
IE does not seem to make the post using the following code:
$(function(){ $("#update").click(function(ev) { var target = $(ev.target); if (!target.hasClass("add_btn")) { return false ; } var li = target.parents("li"); var _title = li.attr("data-title");
I am building a web app that uses alot a jquery including a function that reaches out to a webservice using $.ajax to grab data and return to tdata to the web app. The function that makes the call is outside the ready block but is called in the ready block to make it run on the load. After the load I use a timer to keep calling the function to keep things up to date. But after the first run the function does not seam to work. This might sound wierd, but the ajax function appears to run after the initial go, but it always returns the original request, it does not make new request to the server. I use fiddler and watch what going on and after the initial run method it doesnt make any other calls even though I see the ajax method being stepped through using debugging software and see the AJAX call being attempted and returned successfully.

Is there a way to post from a .net page with server form controls using the jQuery .ajax method? The .net page is expecting the server contols so I'm not sure how to handle it so when I serialize() the form it doesn't know what to do with it.
So I end up with tens of thousands of these undefined global variables. I believe this is cause my script to fail and I am wondering if there is an easy way to fix this short of either editing the jquery library to delete these (can this be done?) orwritingmy own ajax function.... All other variables are getting smaller at the point of failure which isconsistentregardless of other changes made to the program.
I am testing on google chrome, but would like it to remain able to be used across updated browsers.
