JQuery :: Checking For Well Formed XML When Using Ajax Function
Jun 3, 2011
Is there some way to determine if the XML returned via a $.ajax() call is well formed? My experience is that if badly formed XML is returned (eg: a missing ">") then the return value is "success". However I notice that data.childNodes[1].textContent contains a very specific error message that points to the line which has the syntax problem. Is there any (documented) way to know if the "success"-ful call to $.ajax() actually returned a poorly formed XML file?
My question is why isn't this working? that it's probablybecauseit's been loaded dynamically andif ($('#load').length) is not checking dynamic content - but how would Iamendthe if statement to also check dynamic content?
I'm having a problem where a button no longer triggers an event after I changed it through an AJAX call.Problem is, once AJAX has updated the DIV, the contents in RAM is different from what I see when I check the page source (CTRL-U in FireFox/Chrome).What tools are there to display the current contents of the DOM? I generally prefer to use Chrome/Iron, but if there are better tools for Firefox, I'm also interested.
I am making a sign up form, and i want to show "id not available" or "available", while user looses focus from a text box , without submitting the form. same as it happen in twitter while signing up.
I have a signup form that the user fills out. Among other textboxes, there is an Email textbox, and a Password textbox. These are the two I want to do some Ajax work on.
Right now I'm choosing to go the onblur approach, but is there something better? I'd really like Ajax to go into affect when the user has stopped typing. I know there is key up and key down, but that won't really be too good for what I'm doing. Besides that though, this isn't the real problem.
My problem is this, when the onblur function is called, I want it to return text to a specific element on my HTML page depending on if the fields are valid or not.
Anyway, if the email address for example is valid, I want the valid class to get the response. If it's invalid I want the error class to get the response.
Here's my javascript (right now I'm only trying to implement the Email field):
function checkErrors(str) { if (str=="") {
[Code]....
Now the way I have this set up now, both classes are going to get the text, correct? Well I of course don't want that. I don't know how to have it set up so that only one class gets the response depending on what the result is.
When I load a JSON file locally, I receive the following error in my Firefox console: "not well-formed / file:///<fileLocation>/data.json / Line: 1 / {}". The loading otherwise seems successful, as I can interact with the loaded JavaScript object. For this example, I'm loading an empty JSON object, but this error occurs with non-empty JSON objects, too.
I have a document that I'm using jQuery.load() on to grab some external XHTML.Within this XHTML, once loaded, I want to also load some .js files andexecute some more jQuery.However, when I do that, the browser chokes on the comments in the .js file:
And my question is how to make it display error if I have entered letters in the age box or numbers in a name box? Currently I have only if it is different from 1, so what should I write instead of 1 ?
I'm sure that "insert.php" works because I've tried the <form method="POST" target="insert.php"> And it adds to the database through "insert.php". But when I remove the 'method="POST" target="insert.php"' And replace it with $.ajax() it won't work.
Here's the code: $(document).ready(function(){ $("#submit_wall").submit(function() { var message_wall = $('#message_wall').attr('value'); var message_wall = message_wall.replace(/</g, '<'); var message_wall = message_wall.replace(/>/g, '>'); var message_wall = message_wall.replace(/<.*?>/g, ''); var FeedUNum = $('#FeedUNum').attr('value'); var FeedConn = $('#FeedConn').attr('value'); $.ajax({ type: "POST", url: "insert.php", data: "FeedUnum="+FeedUNum+"&message_wall="+message_wall+"&FeedConn="+FeedConn, success: function(){ $("ul#wall").prepend('<li style="display: none;">'+message_wall+'</li>'); $("ul#wall li:first").fadeIn(); }}); return false; });});
I thought that the value of startDate would end up as the defaultDate param for datepicker. No luck. Only an obscure little message in firebug console: "missing: before statement"
Im trying to do the following thing, I have a function in javascript which I want to use to call anAJAX event, during this event the variable that is set in the function needs to be passed to the file called by the AJAX event. Basically I create 2 different versions of the same stuff inside the AJAX called files using the variables. But im running into some cross browser related issues, this all works fine in FireFox. However in Internet Explorer it sometimes works but gives javascript errors on line 99999ish. I have the following setup:
My index (currently calling startExample via onclick):
var exampleTest = 1; function startExample() { example = exampleTest;
I have created a javascript object (ajaxQue below) that contains a method (this.get() below) that is a wrapper for the $.get() function and another method (this.jobCompleted() below) that is the callback argument for $.get().
The callback method refers to the javascript keyword 'this'. But 'this' doesnt seem to refer to my instantiated object as I would have expected, instead it seems to refer to something inside AJAX. So I can no longer refer to properties within my object (e.g. 'this.prop1' below). I have included a simplified version of my code below. Is jQuery messing with my callback function ?
what I'm trying to do is to automatically launch a function before going in the $.ajax ({success}); method. I've this:[code]My problem is that I first see "success" and then "ajaxSuccess" or would have the opposite.dataFilter function doesn't help me because I can't detect if query is successfull or not and not have the XMLHttpRequest.
For starters i'm new to jquery and javascript, hence my post here. I've tried to do research but I'm not finding the answers. Here is the problem. the web page i'm working on has 2 area's or panes. one that changes dynamically via ajax and one that stays the same to control the dynamic area. The dynamic content is loaded with the following function to load a given page into the <div>.
[Code]...
When the content is loaded into the div jquery does not work. More specifically i'm using the jquery ui datepicker. The page that is loaded via loadPage() work fine if its not called by the function. but once it is it seems all javascript does not function.
I want after send a comment, that message submit online and insert to database, Without Refresh Page. In this code, $.ajax function worked , but success: function(html) does not work(document.getElementById). I do not know why it does not work!? What do I do?
I'm using ajax to process a form. But my form has textareas in them. Its not passing the textarea values. Here is my javascript code: $.get( "process_order.php", $("#order").serialize(), function(data){ $('#loader').hide(); if(data) { pTag = "<img src='[URL]' width='200px'><br />Order Saved"; $('#popup').empty(); jQuery("#popup").append(pTag); jQuery("#popup").dialog('open'); } else { pTag = "<img src='[URL]' width='200px'><br />There was an error!<br /><font size='1px'>" + data + "</font>"; $('#popup').empty(); jQuery("#popup").append(pTag); jQuery("#popup").dialog('open'); }}, "html" ); I just have a simple textarea section and I NEED to allow HTML code in that text area.
