so I'm trying to get a large amount of text back to my ASP script
on the server. My large amount of text is the source to a web page, and
I want to preserve the formatting on it, ie the indenting. Before any
of this the only way I got stuff back to the server is with query
strings. Now I'm pretty sure there's other ways to get data back to the
sever besides query stings but I'm having trouble finding them. Can
somebody point me in the right direction or tell me how?
What would be the danger in having a lot of hidden iframes? i.e. potentialy 30-40. I need to store a bunch of data and thought about using hidden iframes to do it but wasn't sure if this would bog down my page or not. Opinions? I know this is not an IDEAL way to store data but I'm at my whitts end and it sounds like a nice workaround right about now!
I am using Ajax to send a large text box to a server script, however, when the textbox has a lot of data it fails. Is there a better way for me to do this? Here is my code.
Code: <script type="text/javascript"> function testmail() { if (window.XMLHttpRequest) {// code for IE7+, Firefox, Chrome, Opera, Safari
I've been using localStorage to store a large amount of data (> 5mb). I know that most browsers limit localStorage to 5mb. However, on the specification site it states,
Quote:
User agents may prompt the user when quotas are reached, allowing the user to grant a site more space. This enables sites to store many user-created documents on the user's computer, for instance.
I'm using the .html() function to update information in a div whenever a button is clicked, like this:
$("#myPic").click(function() { $("#myDiv").html("//new content for div goes here
However, for some of these new sections, the html is QUITE lengthy. can i store it on a separate file in the same directory and somehow import it?? Is there a better way?
I'm working on a project that involves a page with a large amount of images (sometimes 400+). What's the best way to handle this? Should I track the loading-state of all of them, or is it save to assume I can do stuff as soon as the last image is loaded? So.
I'm looking for a very simple image gallery solution (no lightbox or something other fance) with a large image and a x amount of thumbnails at one off the sides, where the big image change whenever another thumbnail is clicked, without page refresh. ( a fade transition would be nice)!Which Plugin, preferably as light as possible, is the most suitable for this task?
At the moment I have two div tags in my main index.php file, called "flowchartDiv" and "buttondataDiv".Now what I'm trying to do is when ever a image is clicked, "Image of a button", it is added to the database and the "flowchartDiv" must reload in-order to reflex the new button added to the database.I will settle for the "flowchartDiv" reloading after a set time but I actually want the "flowchartDiv" to reload every time I click on the image buttons in the "buttondataDiv".here is my code for index.php file:
I have a rather large background image as part of the website layout. It's basically the header. It takes a while to load. I wonder if there is an AJAX or javascript loader that can show a loading gif before the image is loaded and then be removed so it doesn't show when you change pages next time.The CSS for the header is below.what code to use for a preloader? Would be grateful for info about this
I have a element when click, it will trigger some other elements to be selected. and those elements will trigger elements in next level.
It is a three levels hierarchy so to speak. but each element will send an ajax request when selected. Those requests will become out of control especially when I repeatedly click the root element.
Can I queue those XHR request in a queue and send them one by one? or maybe add a delay before send so that they can collect their information into one batch request and send one request after that.
I am building a large registration form. In this form, a sponsor/educator must register himself or herself and then may add up to 6 more " delegates" in pairs. The first two pairs registration info on the form is shown by default. I need to hide the other two pairs until when/if the user clicks on a button to add two more delegates at a time. I used javascript to show or hide the parts of the form that I had put into two divs and adjusted the css display attribute. However, my problem was that, if the user filled out the sponsor/educator section and the first two delegates, and then decided to add two more, when the user clicked on the button to show the part of the form for delegates 3 and 4, it reset all the previous visible form fields to empty. Not good. So, I thought, maybe AJAX.
I created the request object (I am a relative novice at AJAX), had it grab a text file with the code to insert into my target div, in this case a div with id = "delegate3and4". Surprisingly however, it still reset the previous form fields to empty. Am I misunderstanding how AJAX is supposed to work? I figured that, because it does not refresh the page that this would not happen. In fact, to test this out, I created a simple page from scratch with just a single input field and then used AJAX to insert the file in a div after this field and it did not reset the previous input. So, I am totally confused about why this would be happening on my live page. The page is a php page as it submits the form to a php script for processing but I don't think this should make a difference.
today I updated my Firefox from 3.5 to 4.0b3 and it seems that the AJAX success callback is not longer fired. Firebug shows the correct response but the function is never called. Is this a Problem of the FF Beta, or is Jquery responsible for this?
And i have gone through this forum and other forums for a simple fix ... since so many have had this problem..but i have nt found anything that seems to work hence i am posting this problem
I dont know what i am doign wrong i have used debugbar and i can seethe html content that comes back i have used fiddler and i see hte html content that comes back there....the xhr stat =200 so every thing is good..yet it doesnot replace the the content $("#updateroster").html(data).
The answer to my question is probably very simple, but I'm having trouble making this work.
I want to access a local csv file, rearrange it into an array, and use the data later in my script. The logic of this in psuedocode is [code]...
Since the massaged data are in the callback, they're not available at ***. I've tried declaring the variables outside the callback as shown, but this doesn't seem to work either. I'm thinking there must be an easier way. Is there?
<span style="font-family: courier new,monospace;">Hello all,</span><br style="font-family: courier new,monospace;"><br style="font-family: courier new,monospace;"><span style="font-family: courier new,monospace;">I've recently started with jQuery because I wanted to use it for posting details from an login form to a PHP script which should return whether the user is authenticated ox not.</span><br style="font-family: courier new,monospace;"> <br style="font-family: courier new,monospace;"><span style="font-family: courier new,monospace;">For this I use $.ajax, because of it's flexibility and I prefer to use it in this implementation. Reading (jQuery docs and examples) and searching a lot did not solve me on one issue: fetching the data in the callback to the global scope.
I have been trying to figure this out for a few days now and have finally come to the point where I think I got it but may just need a little push to get what I want.
Heres the situation:
I have this function that uses ajax to access a database and returns the results in the responseText. That part is working fine, I have confirmed that the responseText contains the information that I need
**************code***************************************** //new ajax already created and assigned to the variable xmlhttp// var response_recieved = "some data"; function get_answer(Table_Name, Field_Name, Data_Type) {
[Code]....
As evidence by my posting, this is not working correctly. The variable response_recieved is coming up undefined outside of the callback function assigned to the onreadystatechangeproperty.
Based on the information that I have gathered online from various forums, I believe this issue has to deal with a problem with closure in the callback function assigned to onreadystatechange property. I don't think it has any. Based on the fact that there is no anonymous function in that function. But my problem is that the call back function is anonymous itself... I think???
get the variable response_recieved to survive outside of this function.
This could appear under Ajax, for example, you could have multiple objects that make a singular ajax call (say an RPC-like request) and you need to update the object that made the call during the callback with the result, but it doesn't have to be. The particular problem I'm thinking about happens to be ajax, particularly with multiple objects accessing the same ajax request (meaning I can't use a global or temporary variable).
One way that seems like it would work (just thinking about it in my head), is to create a hash, and to pass the key through the request, store the key in the response, and pick it up on the callback side. Then remove the item from the hash when done.
What I noticed is that my error callback is fired every time. MyService.asmx: [WebMethod] public FileInfo[] GetFileInfo(int Id){ Proxies.ServiceRef.ServiceClient c = new Proxies.ServiceRef.ServiceClient(); return c.GetFileInfo(Id).ToArray(); }
The Jquery code where I am getting error: $.ajax({ url: url, data: jsonData, type: "POST", contentType: _I.contentType, timeout: _I.timeout, dataType: "serviceproxy", // custom type to avoid double parse dataFilter: function (jsonString, type) { .....
When I debug using firebug the response is as follows. {"d":[{"__type":"Proxies.AFARServiceRef.AssignmentInfo","ExtensionData": {},"AssignDate":"/Date(1317748587667) /","AssignFileName":null,"ClaimId":"PA026195","ClaimantName":"Rachel Weiss","FirstContactDate":"/Date(1302678000000)/","FirstContactTime":{"Ticks":433800000000,"Days":0,"Hours":12, "Milliseconds":0,"Minutes":3,"Seconds":0, "TotalDays":0.50208333333333333, "TotalHours":12.049999999999999, "TotalMilliseconds":43380000, "TotalMinutes":723,"TotalSeconds":43380},"Id":5257, "InspectionDate":"/Date(1302246000000)/","StatusId":1,"SubmittedCount":5, "UploadedCount":9}]}
I am trying to retrieve json data from the world bank's API, here's my code: <html> <head> <script src="[URL]"></script> <script type="text/javascript"> var theData; $(document).ready(function(){ $("button").click(function(){ $.ajax({ url: '[URL]', success: function(data) { /*this alert message does not show*/ alert(data); }, dataType: 'json' }); }); });
</script> </head> <body> <p></p> <button> Get World Bank Data </button> </body> The callback function is not executed but there is response when I checked it using firebug.
