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)
I have an object with a single Method to load content from a xml file. The problem is... how do I add a property to the object to store the data loaded?? I tryed adding a simple Array inside the object, but didn't work.
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?
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:
I would like to use jQuery to prepopulate a form - ie make a call to a php program to get data from a database and pre-populatea form with appropriate data for the user. Can anyone point me in the right direction for some examples on the simplest way to do this?
I am writing a small data entry screen that will post the form data to a page and return a message. But i cannot get the Success or Error functions working properly.
Here's the code where strData is the posted querystring of:
I'm not sure whether it should be in a form and using the onsubmit or click of a button.
I have created a servlet that does nothing more than create a XML file.i have got some JQuery code that reloads the servlet to get the XML data.This works fine and i am able to load the data i want, the problem i have is that when the data is loaded to the jsp page it displays [object Document] in front of my output.
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"}; }
I want to pass the value to my object id = "Parameters" How can I do that? I had tried the code as posted below but it couldn't work. I'm using document.all.Parameters.data = tempParams[0]; to pass in the data to
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?
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.
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.
I am having trouble populating elements from the following Yahoo RSS feed: [URL] I need to show the current weather conditions when a button is clicked. Here is what I have so far.
[Code].....
I need to populate the <h1> and two <p> elements. I know that the copyWeatherData() and getWeatherData() functions are not coded properly.
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
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.
I am doing some custom development in Salesforce.com's Force.com platform.
I have built a custom object (table) called "conferences" which has 2 fields named "Conference name" and "Number of attendees". I need to pass data from these fields to a Java Script Alert box. the Javascript code I need to use to make this happen?
Basically I need to know the method, procedure or function to use to pass data from the object (table) into the Javascript alert box.
I'm currently working on a project using Ajax (just for a little background) bascially I click on a button and it loads the editing tool on the paragraph tag i've clicked on (well thats the idea). The ajax bits themselves aren't the problem I appear to have a this.elementId in my class loosing data or becoming undefined somehow. Code:
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.)
I am using .each to find each form and attach validationEngine with it. When validationEngine success, i want object of calling/owner form. I am trying this, it is alerting that is is object. But i am not able to access "action" of form using this.action.
