JQuery :: Gather Form Data Into JS Object?

Mar 24, 2011

I'd like to know if there's any method to gather form data into a JS object, just as form POST would have sent it to the server. I think such method would be helpful to tweak the parameters a bit, before submitting it to server. Although I could do that via modifying 'value' of 'input' elements, I think it'd be helpful if jQuery can gather the post data in a JS object and return it (so that, for example, I don't have to traverse the form and deal with selection and radio button input elements)

Maybe we need a reverse function as well: given a JS object, do a POST with it, just as if there were a form with the said data, and it's submit were invoked (i.e. not via. AJAX, but load the entire page from the POST reply)

JQuery :: Receiving And Alert With [object Object] When It Should Be Alert The JSON Data

jquery code:

$.ajax({
url: "validate_livestock_form/index/",
type: 'POST',
dataType: "json",
data: form_data,
success: function(data) {
alert(data);
[Code]...

php page is echoing out:{"species":"Please select a species!"} I double checked the response from the php and firebug shows the same. On success alert is not alerting the JSON data instead, I'm receiving [object Object]. Why is that and how do what should I do to fix this?

JQuery :: Form Data Not Displaying In Textarea On Subsequent Return Of Data From A Call?

Oct 5, 2011

Relatively new to jQuery but have a problem with getting data to display.Using a webform with 2 forms. User slects and inputs data into the first form, clicks a button then using jQuery .ajax submits the serialized data to a php script. The script processes the input into multiple paragraphs of text which is based on the input from the first form.The data is returned to the webpage and displayed in a text area (of the 2nd form) where the user can edit it to fine tune the wording. The 2 forms are displayed in different tabs so it is easy to move back and forward between the 2 forms.

The problem occurs when the user goes back to the first form and enters or selects different text and then click the submit button to generate a whole new text for insertion into the textarea on the second form. For certain fields the modified text is displayed.However if the whole of the text in the textarea is deleted, then the user clicks the submit button to re-generate the text content area then nothing at all is ever interted into the textarea. If have user alert to check that data is returned from the php handler and this text is correct. BUT when I click on the tab to see the textarea (id is "draftrec") there is no text inserted. The relevant function is below and the line that should insert the text into the textarea is:

$("textarea#draftrec").html(data).show();
//------------------------------------------------------
$("form#form1").submit(function(e){

Data Object

Nov 23, 2005

I have the following data object. Each string in the "lib" element
represents a new record. I need to display each of these records in
html table format so I can be able to sort on each column. How can I
get each string from each element into its own row, or is there a
better way to populate this data object?

var jsData = new Array();

for (var i = 0; i < 4; i++)
{
jsData[jsData.length] = {lib: "string1,string2,string3,string4", id:
"num1,num2,num3,num4", com: "string1,string2,string3,string4"};
}

the html table output should look like:

string1 | num1 | string1
string2 | num2 | string2
string3 | num3 | string3
string4 | num4 | string4

Getting At The Binary Data In An Image Object

Dec 8, 2005

I've search far and wide for an answer, so forgive me if this is a
stupid question. (Well, it probably is.)

Consider the following javascript:

var foo = new Image();
foo.src = "http://some.server.com/some_filename.gif";

Now, the browser will retrieve 'some_filename.gif' from some.server.com
and put it into the object foo. What I want to do is then subsequently
analyze the actual binary data contained inside some_filename.gif.
(Specifically, I just need to look at the first few bytes.) Is there
any way to do this in just JavaScript?

Get The Binary Data Of An Image Object?

Dec 19, 2009

I'm trying to get the binary data of an image object.

I've found articles to writing binary to be the source of an image, but they don't tell you how to do the reverse. Pretty much, after the page loads I want to do something like.

myImg = document.getElementById('cow.jpg');
binData = myImg.somethingToGetBinaryDataPlese

For those that are curious why I'm doing this its for another project I'm working on where I store the binary data somewhere else after load, but for technical reasons this has to be done client side for if I do it server side I'm not getting the results I need for this project.

How To Read The Streaming Data From IE Xmlhttprequest Object

Apr 3, 2006

I am going to use the server push

for streaming the data by keeping the connection open. At client side,
i am having the XMhttprequest object (i.e ActiveX object of IE). When
the data comes, onreadystatechange method get callback on state 3 but
it doesn't allow me to read the data from the object. It says 'The data

necessary to complete this operation is not yet available'. Is it
possible to read the streaming data from the XMLHttprequest object in
IE?

I know Mozilla supports to read the data, when the ready state is 3. In

Internet Explorer, how we can use the XMLhttp Active object to read the

streaming data.

Create Image Object From Binary Data?

Mar 2, 2009

Im trying to implement dynamic images on my site. Basically, there is a list box, and when the user selects an option, it calls a service that streams back a base64 encoded image that will be the preview of what they're looking at.in FF you can do this: img.src = "data:image/png;base64," + args ; This doesnt work for IE. from what ive learned, IE doesnt support this type of inline coding.

I was thinking that maybe the next best solution would be to convert the base64 back into binary, and set the new image object to that source. something like this:

Code:

var img = new image();
img.source = binarydata;

now obviously, img.source isnt a real method. but i would like to be ale to set the binary data as the image.

possiblities: Is there anyway to save that binary as a file on the client? and then be able to reference that file as the picture img.src = "images/" + newfilename;

Some other alternatives is to stream back a reference on the server to get the picture, this would require two callbacks, which i dont want.

Also, there is a method of turning the image into a big array of HTMl elements, and each element holds a color, being a pixel. im not doing that, that is the biggest hack job i have ever seen.

Test Object Equality Using Data Inside - Not References - Possible?

Jan 29, 2009

Is it possible to test whether two objects are equal using the data they contain inside and not comparing their pointers with ==?

Well actually of course there is but...

Is there a way to do it without actually looping through the object, instead maybe something that came with JS? (something like a .equals() method from other programming languages.)
