Ajax :: Loading A Set Of Objects At Runtime Wit Html?
May 5, 2009
I need suggestion for this.After a particular option selection in my page,how to replace the rest of the contents of the same page with its response,and too making the select action invisible... can i do it using ajax wit html. for example,i have a select option,where for each option is attached a new set of objects,i want them to be loaded on the same page at run time,without page refresh...
I am loading an entire page in ajax, but I just want to load a fragment from it. Using the .load() function, you can do this by adding a selector after your url like 'getPage.php #myDiv' etc, how to do it using the .ajax method.
I'm trying to get the "d1" div to be populated with the contents of the "my2" div on the second page. I don't want to use the .load() function, I want to use the .ajax() function. I can get this to work if I just use: $('#d1').html(data); instead of $('#d1').html($(data).find('#my2')); but the former results in the entire html contents of the second page being placed into the "d1" div, and I only want the fragement.
Im wondering if generating html objects such as tabels and rows in javascript is faster than typing the html directly? Seems when you do it in javascript you have to download alot of code and would slow down displaying the page. while if you just type the html, it requires less bandwidth and display faster?
is parsing html to display in browser slower than doing it through dom to display the same html objects on the page?
Im trying to add some simple display features to a web application and am running into some unexpected IE8 behavior. Basically, the app runs some database retrieval from the server using Ajax techniques, and during that time (say, 30 seconds), I want to just give the user a clue as to whats going on. It could be as simple as a wait cursor. More interesting, I prefer to unhide a div with an animated loading icon, then hide it again when loading is complete.
I tried to load 1 html through ajax and javascript and it worked.But i want to load more than one and i cant.I thought that it would be a good idea to put the ajax files to the external websites and put the same load button.I tried this idea but it doesn work.I can only load one external website.
I have a jQuery script that loads and displays a small window on a mouse hover. I use jQuery AJAX to load the content on that window. Having that, I noticed that loading the response from php file (which does not have a php code, only the file has .php on its name) is slower than the same file content with .html name. I wonder if this is a common problem or there is some issue with my codes. I will post my code if needed (if that seems to be the problem).Note: I mentioned that there is no php code in the php file because I am only testing the performance currently. After it is developed, there will be (obviously) php code in it.
Can someone explain to me the difference in the book and the sample code? I am not an expert in javascript, but I am an experienced programmer in C++ (Borland) and other programming languages (mainly CVI which does not support OOP).
The book uses try and catch statements to init the XMLHTTPRequest object, but the sample code uses what looks like (to me) an array of functions. Can someone please explain the sample code? It is probably straightforward to a javascript programmer, and I can see what is happeneing, but I have never seen the square brackets construct before. Code:
I've seen lots of examples of invoking the getElementById and they always are given as a method of the document object. That is, they always show something like: Code: var theElement = document.getElementById("Fred"); But what I'd really like to do is to get an element from the document, but starting at a particular element in the hierarchy of the document.
For example, suppose I have two forms, form1 and form2, and they both have elements in them named "Fred" (and, yes, I know I shouldn't do that). But what I'd really like to do is something like: Code: var theElement = form1Element.getElementById("Fred"); assuming that I've already somehow retrieved the form1Element.
But Javascript reports to me that getElementById is not a method of form1Element. And the fact that every example I've ever seen of getElementById invokes it as a method of document would seem to bear that out. The thing is, on the microsoft site it actually shows the generic form of the method as: Code: object.getElementById(iD)
Which would seem to imply that it's more generic than just being a strictly document method, that perhaps it's intended to be a method of at least some additional HTML objects. Since that doesn't seem to be the case, how might I go about doing what I'd like to d, which is find the occurrence of the element, by its ID, but only within a particular section of the document hierarchy?
I am ok with using objects creating classes if someone else defines, but when it comes to defining my own, I hit a nasty brick wall... I am using an XML/XSLT wrapper called Sarissa to help with programming a utility to transform XML into HTML in different views. For this to happen, I have created a Loader class which loads in XML required. I am aware of prototyping for binding methods to objects (as opposed to replicating the same method every time an instance is created)... The aim being I want to create a progress bar for the essential files that need to be loaded in. Presently I have them load in Synchronous mode just to get the utility working, which I know is poor, so would like to address it.
I'm trying to figure out if there's an easy way to execute all the Javascript code included or referenced in an HTML document even if given code references DOM objects.I basically have some Javascript code that makes a POST to my server. The POST payload includes a unique identifier for that html page, so I know if the JS was successfully executed if I see the unique identifier in my server's logs.
At first I wanted to test if the javascript in 5 pages worked, so I manually opened the 5 sites and verified my logs. I then wanted to see if the JS in 100 pages worked, so I wrote a little script that launches 100 tabs in FF staggered (I also used a nifty tool -- autocomplete, to close old tabs). I then wrote a utility to go through my server's logs and verify that the 100 unique identifiers that I was expecting were there... So this also worked fine!But now I want to move forward and test 1K or maybe even 10K sites. Is there anything I can use to execute Javascript embedded in an html page? Hopefully asynchronously?
In firefox, i look through the DOM and its showing me that both xmlHttpRequest and ActiveXObject("Microsoft.XMLHTTP") are undefined.Also if one could check the ready state methods I used, I'm not 100% if they are correct eg. xhttp.onreadystatechange = loadBlurbs() and if null is the value for a failed loading procedure.lasty, can I do this processBlurbs() = getElementByTagName, and then, processBlurbs() { this.length, this.child etc. ? }
Code: <script type="text/javascript" language="javascript"> var blurbdoc; var blurbs;[code].......
I'd like to do something like this: After the page is loaded I have some forms with submit buttons. The buttons have a class called "open". By clicking any of these buttons the script is using AJAX to take some data from database and add some HTML to the document. This part of generated HTML has also buttons with a class "open". By clicking any of the new buttons script should do what it does with the old ones. The problem is I have no idea how to "refresh" a click function. After generating HTML it "sees" only the old buttons.
Here's some code:
$(document).ready(function(){ $(".open").click(function(){ var idVal = $(this).parent().parent().find("#PlaceId").val(); if($("#admin_places_"+idVal).html()=='')
I'm have some javascript objects with arrays that should be transferred as php array.Its posted by ajax httpRequest.How can I return php array, from the javascript?
I have an object with a member function that changes something on the objects state. This works perfectly fine in the easy case. But when I use an $.ajax call within the function it doesn't work. Here is the example code and failing QUnit tests: [URL]
On the following page:[URL]I would like to load in content from an xml file, when the user clicks on one of the products from the sidemenu. The content will be an image and text for each type of headphone. I've been looking into it and I thought the best way would be to have 1 XML with all the content for each type instead of having one XML or one HTML for each type.
Is there a way in Javascript or Jquery to return an array of all objects underneath a certain point, ie. the mouse position. Basically, I have a series of images which link to various web pages but I have a large semi transparent image positioned over the top of the other images. I want to find the href of the background image that the mouse pointer clicks over.
I'm currently working on my portfolio website and would like to have information about my movie clips be retrieved from an XML document when a thumbnail is clicked. I am building my website in HTML and would like to retrieve the Xml using JavaScript.
Im loading a div of an external html (#right_in) into a div (#right) in my main movie this way:
Code: var toLoad = divobj.id+'.html #right_in'; function loadContent() { $('#right').load(toLoad);
[Code]....
Is it possible to specify that the DIV has to load always at y=0, ie from the top? Because when I load another external div into my main div firefox keeps the latest position (if I scrolled before it loads the new page at that point).
I have a login button which takes the user to the login page. Now... this to me seems like a slow way of logging in. I would like users who have javascript enabled to click the login button. Instead of them being forwarded to the login page, I want the login form to magically pop up on top of the web page.
I can do this, I can creative a div, add the html and probably with a bit of trying - get the user to login. However I have a question. For maintainability, I want to have create a separate HTML file, how would I insert this into my page using Javascript?
Furthermore speed is crucial, is there a way to have this fragment load in the background on every page? I am not sure what would be best, i just don't want a second or two wait when the button is pressed. Basically - in short - how to I load this file fragment? What is the fastest way to do this?
