JQuery :: Update DOM After Setting Value To A Field?
Sep 2, 2010
I'm developing one application that have two iframes. These iframes are ARS forms.So, I need to transfer information from one to the other one and after that, call one save method of the ARS form. (Ps: both have the same src attribute, in other words, the same form).
I want to create a javascript function where I have a dropdown list and onChage I want to update a txt field with the current date in the dd/mm/yyyy format.
I've done a fair bit of development in php, html and css, but none whatsoever in javascript so far.
I've found myself looking to jQuery as a potential solution to an interesting problem that I'd like to solve: I have a basic CMS that clients can use to manage the rental of items (caravan pitches to backhoes). The site administrator gets to enter the details of their products, prices and so forth, and then visitors to their site can see the availability of their products on a dynamically generated calendar - and book them online.
Part of the CMS allows the creation of 'seasons' - periods of the year in which a product's rental price changes - for special offers, etc. Different seasons are shown on the calendar using different css markup that the admin can change in the 'create/edit season' form.
Clearly, I can't expect Joe Siteadmin to type correct CSS and, ideally, I'd like to avoid limiting him to a swatch of pre-generated choices. So, having been seduced by the sexiness of the jQuery UI calendar plugin, I was thinking that it ought to be fairly easy to provide a jQuery color picker of some sort on the 'create/edit season' form, maybe with some radio buttons to dynamically link the picker to change background, text and border color - and update the relevant css rules for the colors chosen, on the fly, in the relevant input field on the form.
I was making mysearchfieldI though jQuer may help update one dropdown box when a value in one box is updated.
So, my search goes like this, Search for Pet [PetDropDown], Search for Breed [BreedDropDown], Search Location [Text feild] and Search Price [Text Feild].
So in this system i want the [DropDown] box to automatically update it self, with no reloading, thats where jQuery comes in (im guessing) with a list of Breed that link with the Pets DropDown. So if the user picks Dog, then the Breed Dropdown will show Breeds that areassociatedwith Dogs, such as Collie, Jack Russell or Staffordshire Bull Terrier. If a Pet isn't selected then nothing will show.
The information come from the data and a phpstatementfor the Breed DropDown would be as such: $sql = "SELECT id, title, value, type, cat FROM site_cats WHERE type = '[PetDropDown]' "; of course it wont be [PetDownDown] but as a $value such as $petType or $pet.
Environment is PHP - MYSQL When the user changes the value of a select drop-down, I want to use Ajax and query one table of my database, retrieve three pieces of data, and place the data in three separate text fields in my form. Is there a simple tutorial out there that explains this?
I get the general concept of the separate php file for the query, but I'm pretty much lost.
I have an hidden field in a form defined as follow: <input type="hidden" name="previewText" value="" /> To assign its value I used: var contentText = "<h2>Order Preview</h2>"; $("input[name='previewText']").val(contentText); It works fine but the html code is lost. Is there a way to retain the
I have a form that I'm setting an initial value for every field using jQuery and the value of "title" attribute. When you click in the field, the initial value clears out. I need to validate the form, and make the user enter something in each field is indeed valid data.
I've got this hidden div that pops up using jQuery when the login menu item is clicked. <div class="entry-wrapper" id="reg-login" style="display:none;"> <div class="t"></div> <div id="loginFormHolder" class="c"> <div class="close"> <a href="index.php" class="spotlight-close"> </a> </div> <!-- close --> <div class="login"> <div> <!-- blank --> ..... What I'm trying to do is setting the input focus on the user_session_username text input and the code is not working. The div pops up but the focus is never put into the user_session_username edit field.
I am very new to jquery and I am trying to set the value of a textarea which is not in a form, into a hidden field which is in a form. In the text area, I have given it an id called refnote and ive used the text() to get the text in it. However, the problem is setting the retrieved text in a hidden form field. $('form').submit(function(){ alert ($('#refnotes').text()); return false; });
so, the pseudo code: - on change of input contents, check to see if two input fields are set - if set, update a third field with "loading..." text and a loading gif - use ajax to send data to a url, and get a calculated json response - update the third field with the calculated response
I know I'm getting the correct response, according to firebug: {"pace":"10:00"}
I'm trying to "combine" PHP and Javascript to a possible workaround. I have a test form with two objects;
- a text field - a drop down box; the items are stored in a MySQL table
In PHP I can adjust the items of the drop down box by submitting the form (button) and querying the results out of the database.
In Javascript I can do this without a button to submit the form.
But I have to include all possible values (>1000) for the items in the script... Is there I way to combine the two (on leaving the text field, the items in the drop down box should being build from a MySQL database using the value of the text field...) Can anyone help me out here?
I am trying to create this form to update a field when a certain item is selected from a dropdown menu. I would like to have it to where when heat pump is selected from heating type, the AFUE field that originally has a value of 80 needs to be updated to 7.7. I would also like for the wording to be changed... Instead of having it say Current AFUE or HSPF, have it to where when a Single Speed Furnace or Variable Speed Furnace then it says AFUE below it, when Heat Pump is selected then it says HSPF, and if Electric Heat is selected do not have anything or even delete the whole field.
If you click the link on [URL].. a form pops up. How do I set the value of the URL text field in the form to be equal to the url of the page it originated for i.e in this instance it the value would be[URL]... i believe would set the value to the current url. What I need is the value of the url the pop up originated from.
I'm doing an ajax call to a remote php file... it returns a value fine, and even enters a value into a text field on my form. The problem is, right after the function call to the ajax function, I do an alert of what the field value is, and it doesn't recognize the field value has been changed. Two caveats:
1 - It will recognize the last call's change (if I run it a 2nd time, it'll see the 1st call changes) onBlur="ajaxCall(document.form1);alert(document.form1.ajax Field.value);">
2 - It'll recognize the current call's change if I set a 2 second timeout onBlur="ajaxCall(document.form1);setTimeout('checkFields(d ocument.form1)',2000);">
It seems, although I can see the text field getting updated, programmatically speaking, it isn't reflecting it until everything is done... including any alerts and such.
It's weird seeing the empty alert popup, when I can see the value in the text field underneath it.
I'm creating a page that calculates a number depending on what value is inputted into a text field. I need to create some javascript that updates this new calculated value and outputs it next to the input field. Anytime the user changes the number, it recalculates the value. My calculation is currently being produced by PHP, however if I need to, I can create javascript as well to recalculate these numbers.
i am currently developing a cart for a website at my company.What i am attempting to do is update the grand total field dynamically as the product total (determined by quantity & price) are being populated.Each product in the cart is being generated by a foreach (php) reading from a mysql database.As the total values are not being prepopulated im not exactly sure what the logic would be to get the desired values.
I will also mention im relatively new to the whole web development area, i started begining of this year and feel i could still learn alot about the 'logic' of a computer.If anything is unclear about what i stated above feel free to request additional information.
when the user types a FIRST NAME into the first name textbox this should update the paxname with the value and a space.when the user types a LAST NAME into the last name textbox this should update the paxname with the value therefore at the end of the process the paxname will have the full name of the person in order with spaces in between. also i would like the first name and last name values to be changed to proper case ie John Smith once placed into paxname the update process does not have to be instantaneous, it can perhaps update the paxname textbox when the focus is gone from the field in question, dont mind how it works as long as it updates.
sample code, whereby if I change a field value in a web form (from a drop-down list for example), the value shown in another field is automatically updated to show the needed value for that selected option?
Have the Javascript function below which takes the name of an input on the form passed as a variable so that 1 function can check many inputs as I have up to 3 fields per form that can accept this data range.
function contact_number_check(formObj,field) { var obj = document.forms[formObj]; var regExp = /^([0-9 ])+$/; alert(field);
I am unable to solve two problems creating a contacts form using dreamweaver CS3. My other problem is posted under the heading, "Modify code created with Dreamweaver CS3, to compare two text feilds". For this posting, can someone please tell me how to modify my code, pasted below, so that the "First Name" and "Last Name" text fields are restricted to accepting only alphabetical characters.
Here's my current code

It shows a default value which dissapears when the user clicks on the password field. However, because the input field type is set to 'password', whatever I set as the default value is masked by *
Is there any way around this to make normal text appear but still have the input box masked when they start to type the password?
I'm trying to do something that is slightly complex and I can't find any relevant examples in the usual places,I'm pulling a list of projects (and their IDs) into a select:
