Dynamic Type Of Field Changing Based On Checkbox OnClick Handler
May 1, 2006
I'd like to know if its possible to shift a select option field into a simple text field based on a check box filled by user.
I have an asp form that carries a few select options. One of them I'd like to permit free editing if the user selects a check box just biside the select option, so enableing free editing by user.
I figure this has to be simple, but I'm very green to javascript adn the examples I've found don't appear to work On an html form I have 2 checkboxes (A and B). Both are checked by default.
If the user clears box A, I want to clear box B. I don't want to hit a button, just change the box as soon as the user clears box A. I've attached an onclick= on box A, and created a simple script, but I don't even appear to getting into the script. Can someone provide or recommend an example that actually works that'll do this?
I have a form with a field that asks for a full year. If the year is greater than 20 years ago, I'd like additional form fields to be revealed. If the year is equal to or less than 20 years ago, it will not reveal the fields. (And it should be based on getFullYear(), so I don't have to update the script every year, yeah?)
I figured out how to script onclick functions and some basic .value == functions in order to show/hide just about every type of form field. So I don't need that info. But I'm unsure of how to calculate the value.
So i'm just getting into writing jquery. it's my first scripting language and first time in the field of programing. I have a general idea of what i want to do, but not so much how to get it done. Objective: I would like to change the class of a div "ActiveSelection" to the same name as the id of a clicked link in the "catalog" ul. Here is an example of the HTML
how to Change a Hidden Fields Name based on selected option. The hidden fields name is sent off and I need to change the name depending on what option they select. For if they select MyList the hidden field name needs to be SelectLists[40] or if they select testlist the hidden field name needs to be SelectLists[41]. This is probably way, way off but I've done this and it doesn't work.
Does the following indeed imply that this event is NOT called when an <input type="checkbox" is toggled?
This would thus imply the usage of the onClick handler instead (assuming an action needs to be invoked on check/ uncheck).
W3C Recomendation: 18 Scripts
onselect = script [CT] The onselect event occurs when a user selects some text in a text field. This attribute may be used with the INPUT and TEXTAREA elements.
I *know* the onClick can be used, I am just wondering about the use og onSelect.
I have a form that has a pretty complicated combo box - a user starts typing text, it queries a database for matches, and displays the results to the user. The user can then select the match they desire and it has a value id, which I am currently sending to a hidden field in the form. So, for example: user starts typing in a movie name, Seven - it returns Seven and user selects it. The form submits the id of the movie seven (say 12) to a hidden field.
Where I am stumped: Once a user selects a movie title, I have another drop down select box that is to display the available formats of the movie by querying my database based on the product id (12) and returning the available formats in the list:
DVD BLUERAY VHS
I am pretty good at programming, but I cannot figure this out - how to make the select box fire and return results once the value for the textbox has been captured.
I've created a registration form with sponsorship options hooked to checkboxes. My original form used ASP to keep values in hidden fields to use for totaling everything at checkout time.
Now I'd like to use PHP and Ajax to place the value into the text field related for each option checked.
I'm able to do that making an Ajax call. My problem that I need help with is this: If the visitor decides to uncheck a sponsorship option, the value placed in the associated field remains on the form. How do I replace that value with a null or empty string if they decide to uncheck their original choice?
I've tried JavaScript to no avail so far, both in the client side and server side code. I'm very new at this and I need help. Will jQuery work without having to change a bunch of code?
I have a button that needs to increase/decrease the value of a text field when clicked. This code is working in Internet Explorer and Chrome, but not Firefox.
I have created a user form in which visitors can fill in sections, some of which are hidden or displayed using the onclick to trigger a DIV to display or hide then submit the results to a database using ASP. All works fine with that, however... I have created another page which retrieves the results for an individual's form submission, and I want to hide the sections that were not completed (hidden when submitted). How can I get my page to hide or show DIVs, depending on the value retrieved from a particular field within the database? i.e. if Question1Response="A", show Div ID="A Section" If Question1Response="B", show Div ID="B Section" etc.
So I have to ask some stupid questions and make sure that there is not something wrong in this simple syntax. I am trying to get input field attributes type and tagname by field ID. Heres the code..
Code JavaScript: var type = $('#' + input_id).attr('type'); var tag = $('#' + input_id).attr('tagName');
When I look in firebug I see there is the correct ID in input_id variable and that the input field with that id exists. But for tag and type variables I just get 'undefined' for reason unknown.. syntax is correct or?
how to populate a dropdown based on Another dropdown selection. This all should be a dynamic. Eg: I have two text boxes one is TechID and other is JOB ID. When I start typing Tech ID it suggests me the list of IDs which start with the input string i have put in Tech textbox. When i select the Tech ID the jobs associated to that Tech ID should be displayed in JOB ID text box as a dropdown list.
I am having a problem with the last results. I can't seem to be able to get the input2A and input3A to appear. I don't seem to have a problem with the show and hide after a number is entered and submitted. If anyone can answer my problem I will be greatly appreciated with a prize. I actually have submitted it more than once and I haven't had anyone been able to answer it yet. Code:
I'm finishing up the front-end of an events management application, but I'm running into a problem with my javascript.
Here's the scenario: I have the php application returning all event details into a JSON object.
The object structure looks like this:
Code:
Each event title listing on the calendar grid is assigned "#" plus the event's ID for it's link, just for testing purposes--no problems.
Eventually, I want the user to get a yui container (modal) with the event details, but when I add the onclick handler to the links, the id that gets passed for each of the links is the same, 60 (which is the ID of the last iteration in the loop).
Here is my code:
Code:
I've tried using the var keyword to localize the id, but that produced the same problem.
i have registered a validation function as the onclick event handler. It runs for the first time but does not run when i click on the button the second time. ( this is because i have put an aert box in the validation function and it does not show up when i click on the submit button for the second time)
function validate(form_name){ validate=1; string="";
[Code]....
when i leave all the fields of the form blank then the error message is displayed. But when i click on the submit button again then the validation function does not run.
I am trying to use DOM to create a UI for editing info pulled from a database. The info pulled are the locations of a given company. So, company A might have 2 locations (address, city, zip), and this is the info I want to present.
The way I have it now I use dom to parse the returned XML file and display the location info for each location on a seperate line. At the end of each line I want a button that the user can click which will then replace the current line (just text) with 3 input boxes populated with the values for address, city, zip.
Another button (UPDATE) will then be used to call a function which will update the db with the new location information. This is all no problem, but the part I cannot fathom is how do I associate the "location id" (from the database) with the UPDATE button on a given line, so that when the UPDATE button is clicked the function it activates will know which location (ie row) in the db to update. Code:
I've successfully used the Random-Order javascript on my site for years to shuffle around a number of banners on my main page.I now want to add an onClick event handler to each banner so that I can use Google Analytics to track those exit links, but I can't get the script to work when adding the onClick; the banners just don't show up on the webpage then. I'm pretty sure that some coding needs to happen in the function area below the content section, that just putting the onClick in each item won't do it, but I don't write this stuff, so I have no clue what to do to make it work right. Here's the script WITH the onClick code I would like to add in red. If you were to remove everything in red, the remaining code would be exactly as it currently appears on my site and works properly.

In the below code snippet I'm trying to add an dynamic event in <div id="button3"> when you click at button1, which is added static in the html body. button3 has exactly the same behaviour as button1, but the eventhandler will not be activated.
Im trying to develop an AJAX application which updates a <select> list with a series of <option> tags when the user makes an entry in a field.
Therefore, my ajax application needs to dynamically create <option> tags and append them to the <select> list on the form. I have got this working in all browsers. However, i do not know how to add an "onclick" event handler to each <option> tag that is dynamically created in my javascript code.
Code:
As you can see, i create an option javascript object for each new <option> tag and add it to the <select> list. This works. But how can i also add an "onclick" event handler in the javascript code?
I have a button on a page that is created with the <input> statement - this statement also contains the event handler onClick. The button displays correctly on the page but the event handler is not working - I know this as I put a simple alert at the beginning of the function PrcsBtn1.
<script type="text/javascript" language="javascript"> function PrcsBtn1() { var data2 = new Array();
I have a web page that tracks clicks on certain hyperlinks. I am using attachEvent() to attach to the document onClick handler, for IE browsers. It works fine, except that for about 1 out of every 6 clicks, I get 2 to 4 click events for a single click. I know this because each time the hyperlink is clicked, I write a record to a MySQL database. I write the record to the database by setting the SRC property of an IFRAME on the page, to a tracking script.
If I look at the database, for 1 out of every 6 clicks, I see 2 to 4 records for the same click event (occassionally as many as 6 records). They are at least 1 second and at most 7 seconds apart from each other.
I need to pass the selected option of a <select> tag into a query string, so that the page is reloaded with the selected option already chosen. This will occur with the onclick() event hander, and the query string will be processed using a server-side technology. I'm just not sure how to word the "onclick" handler. Here's what I have:
What is the correct wording to set the underlined portion to whatever was selected? I know it has to be done with JavaScript, since the decision is made on the client-side.
I am have an MVC app that generates a list of rows, of which one of the columns is a button. Here is the rendered HTML for the buttons: <input id ="btnUpdate21" type ="submit" value ="Approve" synchId ="21" /> <input id ="btnUpdate22" type ="submit" value ="Approve" synchId ="22" /> .....
Following is my selector that I use to bind the buttons to my click event: <script type ="text/javascript" charset ="utf-8" > $(document).ready(function () { $('input[id^="btnUpdate"]' ).click(promptForSynchDate); });
I have been trying to access the button Id, though what I really need is the attribute synchId, to use inside of a modal. I have so far been unable to access either one of them. My modal works fine. But the value of either attribute is always "undefined".
Here is my click event handler: (I stuck the alert in there just for debug purposes) function promptForSynchDate() { $(document).ready( function () { var test1 = $(this).attr('id'); alert( 'test1 is : ' + test1); $( '#approve-synch').dialog({ .....
