In prototype with ajax.updater you can chose to show errors in another div than the one you want "real" content in.
Code:
new Ajax.Updater({ success: 'items', failure: 'notice' }, 'ajax_req.php', {
parameters: { text: $F('text') },
insertion: Insertion.Bottom
});
But all information i print out from ajax_req.php gets in the items div. How can i print out errors from ajax_req.php into the notice div?
According to ECMAScript, the root of the prototype chain is Object.Prototype. Each object has an internal property [[Prototype]] that could be another object or NULL.... However, it also says that every function has the Function prototype object: Function.Prototype, it confused me, because a function is an object, for a function object, what is its function prototype and object prototype..For example:
var x = function (n) {return n+1;};
what is the relationships of x, Object.Prototype and Function.Prototype
I am trying to get to the bottom of javascript object, prototypes etc. I have a fairly good grasp of it, but I get confused the closer I get to the base object.prototype. FIrst of all, I was under the impression that all objects descend directly from Object. But some objects (like Array) seem to inherit properties and methods from the function.prototype. So does this mean that the chain is like this:
object -- function -- array Second, I noticed (on the mozilla javascript reference site that object.prototype inherits properties and methods from function.prototype and vice versa!? How can this be? I must be missing something important about understanding the chain?
I am trying to get an alert box with line breaks in it. I want to display a couple pieces of information, and want them broken up. I tried using to get a new line, but kept getting errors in my code.
alert("The combination you have selected: " + + "Background Color: " + color1 + + "Text Color: " + color2)
Of course color1 and color2 have been declared and defined, so I know there isn't an error there.
My original idea of two trains, however pictural it was, appeared to be
wrong. The truth seems to be even more chaotic.
IE implements its standard down-up model: any mouse event goes from the
deepest visible element to the top. By carefully studying fromElement
and toElement properties, one can handle events on any point of their
way up.
NN/FF implements a "Russian hills" style: mouse events go first
up->down (window->deepest element), and right away after that it goes
down->up (deepest element->window). On theory you can handle events
during any phase on any level. On practice this implementation has some
major flaws. I don't have NN handy right now, but in FF we have:
Variables are reaching the php but callback isn't firing. Multiple forms on the page - I've stripped out everything extraneous to try and get a callback. (strangely Firefox 3.0.10 hits the php but breaks while running Firebug(?) and doesn't seem to work in Safari 3.1.2) Sorry if this is covered but been searching and can't solve. php included in case I'm doing something wrong there (as well?) javascript always breaks when I get my hands on it

I am trying to figure out a way to have a page redirect if the mysql connection fails. The issue is that the page is already loaded and the only time this would be needed is if the user tries to perform operations on a loaded page after the session runs out.
So basically, I have a page that will allow you to search for an item using ajax, then select an item and press add which will place the item in another table displaying detailed information. Both operations connect to the database using SESSION variables to save the connection information.
My goal is to use the "or die()" method to print something that will force a redirect because this could happen in a number of places in the site and I want to try and get them all in one swipe.
Here is what seemed like it would be the most promising:
$conn = mysql_connect($_SESSION['host'], $_SESSION['username'], $_SESSION['password']) or die("<script>location.href= '../login.php'</script>");
Unfortunately the javascript never runs.... I tried putting alerts also and nothing, but with firebug I can see they are printed.
how I can ensure that the javascript is executed?
The first div in this example has the position property stated in the div itself.
The second has it stated in a separate style statement, and it doesn't get inherited, though another property from the same style statement DOES.
Firebug makes no complaints.
Is there a better way to refer to the jquery library files, so that you don't have to fix my pointers to my local library?

I'm testing a web site in a local directory by opening index.html from the File/Open File... menu of Firefox. When I use xHttpRequest.send() to retrieve a file to include in my page, the callback's status argument is 8 and req.status is 0. I suppose that the 8 is correct in that the req.status isn't 200 but it seems that for file:// (as opposed to http://) that req.status == 0 might be treated as success. I haven't tested far enough yet to know what req.status would be if the file I tried to retrieve was missing.

Simple enough. This beautiful plugin is what I"m using:[URL]..The problem is, it has no documentation on how to detect a post failure. I know these are rare, but I'd like to code defensively.
View 6 Replies View RelatedFirst, I have to say the jquery form is just perfect and fills very well a common issue for those who need to work with ajax. I would like to know, or even sugest a new feature if it is the case: how can we get, on client side and after an 'ajaxSubmit' call, the error code produced on server side? Is it possible to include such function on jquery form? Because we already have a 'success' callback functionality, how about a 'failure' one?

I want to hook into validation success/failure events, but don't see an API to do this?
i.e. I want to enable/disable a particular set of controls depending on the state of validation.
Is there a way to do this? Am I missing something?
I am returning the following to $getJSON() and not getting any results:
{"QC":["x","y","z"],"RM":[{"DEFAULT":"default_project1"},{"DEFAULT2":"default_project2"},{"DEFAULT":"default_project3"}]}
In the "RM" array there are three objects, each a single name/value pair. The name of the array[0] object ("DEFAULT") is identical to the name of the array[2] object. No results are returned by the getJSON call. Since each object is a separate array value, there shouldn't be any object name collision problems. Note that if I change the name of the array[2] object to "DEFAULT3", the data structure is handled properly.
I'm trying to figure out how to integrate jQuery Validation plugin with the qTip plugin [0] to show custom error message displays. I've
had partial success with the following code:
$("#RegistrationForm").validate(
{
errorElement: "span",[code]....
At this point, that successfully displays the validation failure message in a qTip tooltip when it occurs, but there are two problems
with it:
1) The error tooltip toggles between visible and invisible onmouseover and onmouseout. I'm sure this isn't really an issue with the Validation plugin, but rather something I need to figure out with the tooltip plugin. But, my bigger problem is...
2) Even when the invalid condition is fixed (valid data is later entered into the field), the error tooltip remains attached to the field that was previously invalid, even after the field is valid, and continues to toggle between visible and invisible onmouseover and
onmouseout. I'm fairly certain that this is because I've not yet destroyed the tooltip object, but, I can't seem to figure out a way to intercept the "valid" or "success" event with a reference to the element so that I *can* destroy the attached tooltip object.any experience with combining qTip with Validation, or, if I'm missing something in the docs (I've not been able to find anything like this yet) about how to handle/override event handlers for individual form element invalidation/success. I *did* try attaching a function to the "success" attribute of the validate function, but that seems to only give me a reference to the success label, and not the element that its attached to.
I am needing some help with an error I'm getting from a project I'm working on. First off let me preface this all with the fact that I'm a total javascript noob. I'm really trying to understand what I'm doing wrong. So any help or advice is MORE than welcome. Here's what is happening. I found this code that will duplicate a row in a table and modifiy the name of a input in the row. Well for my purposes I have two different tables I need to work with. (each one idividually) So I changed the code a bit to make it accecpt a variable to use for the table name. (before it was static) and now I'm getting a error. Error: uncaught exception: [Exception... "Component returned failure code: 0x80004003 (NS_ERROR_INVALID_POINTER)" nsresult: "0x80004003 (NS_ERROR_INVALID_POINTER)" location: "JS frame :: http://www.tourandtravelnow.com/admin/scripts/faxPageScript.js :: addRow :: line 14" data: no] This is the old code that would work (only for one of the tables)

i want to set the second container's height according to the first container's.but how to achieve the height of the container dynamically.
View 4 Replies View RelatedI want to do this with js and not with any html/css tables, image fills or whatever other trick, but I don't know how...
Say I have multiple DIV containers below each other, which contain multiple DIV boxes floating next to each other. None of the DIV elements have a fixed height:
<div id="container1">
<div id="box1">some text</div>
<div id="box2">some double more text</div>
<div id="box3">some other text</div>
[Code]....
I want for each container (separately) to have the contained box divs to fit the biggest one in height.
For example, in container1, if box2 contains more text than the others, I want box1 and box3 height to fit box2. And in container2, if box4 has more text than the others, I want box5 and box6 height to fit box4, etc.
In my dreamworld, the solution would be flexible and fully automated, which means, it would look for all container divs of class x or Id x and apply the same rule to all child divs.
I have heard of jquery "equalheights" plugin but I don't think it can do that ? or then I misunderstood something. Could I be using some "get element by class" function and then apply a style.height to the divs?
I am using the YUI library to do the following.I use YAHOO.util.Connect.asyncRequest to obtain some HTML from the server.I then use new YAHOO.widget.Dialog(...) passing it the ID of a dynamically created DIV and then loading it with the HTML obtained earlier.Now the HTML I receive has some javascript in it, and this works perfectly in Firefox.
