Onchange And Onkeypress Event On A Select Dropdown
Jul 21, 2009
I have a select dropdown which has two events an onchange and onkeypress.
My problem now is when I use the keyboard arrows to select an item from the list in a select drop down the onchange is selected(invoked) before I even reach the second item in the list when using opera and IE but working fine with Firefox and chrome.The onblur event does not work either because the focus must be set to following tag
I have a drop down list in html which contains 3 items; Black, white,blue..If i select "Black", a pop up window should come up. (Alert or confirm)JS and need to complete My academic project work.
I am trying to create a dropdown that selects mysql with php. For example I have two select dropdowns the first with types and second with products. So when the types select is click the products from that category are listed in the product select.
I have two drop-down fields that are populated separately from the database. Here is my HTML/PHP code Drop-down field #1 <tr class=bodyTRstyle> <td width="35%"><p align="left">Venue</td> <td class=fieldTDstyle width="269"><p align="left"> <select name="VenueName" class=VenueName><option selected><?php echo $VenueName?></option
<?php $SelectVenueQuery="select * from venue order by VenueName"; $SelectVenueResult=mysql_query($SelectVenueQuery); while ($VenueRow=mysql_fetch_array($SelectVenueResult)){ extract($VenueRow); echo "<option value='$VenueName'>$VenueName";}?> </select></td></tr>
Drop-down Field #2 <tr class=bodyTRstyle> <td width="35%"><p align="left">Results</td> <td class=fieldTDstyle width="269"><p align="left"> <select name="GameResults" class=GameResults><option selected> <?php echo $GameResults?></option <?php $ResultsQuery="select * from result order by ResultDate"; $ResultsQueryResult=mysql_query($ResultsQuery);
While ($ResultsRow=mysql_fetch_array($ResultsQueryResult)){ extract($ResultsRow); echo "<option value='$ResultDate'>$ResultDate";}?> </select></td></tr>
This code works well as long as the two drop-downs are independent of each other. The result table has VenueName as an element, so each venue has a set of result records in the result table. This is how I want to change it: The Venue dropdown will remain as it is. Once the Venue Name is selected I want the result dropdown to populate with ONLY the result records containing a match on VenueName that was selected in the venue dropdown. How do I do that? Is it with a onChange Event? What are the changes that need to be made? How do I communicate to the second drop-down what was selected in the Venue drop-down??
I am trying to add an onchange event to a select tag.
This is my code, but it does not appear to be working.

I want to make one application using javacript or may be it is in ajax. Let me explain my problem: I have one select box name person which have value 0,1,2,3,4,5 . Now i want that when user will select value 1 from select box then person 1 first name , last name input type box will appear only one time in a row. and if we will select 2 from select box then two row will appear naming person1 and person2 like this: if we will not select any value by default is 0.then it will not show any row regarding person.
I am trying to make one application. When we slect value from select box . It will show same type of row according to which value we select from select box.
Let me explain my problem: select box have value 0,1,2,3 . When we select 1 then it will show one row below the select box naming person1 name (input box for name of person1). if we will select value 2 from select box then it will show two row according to select value Like this
person1 Enter Name of person1 person2 Enter Name of person2
By default it have value 0 then it will not show any row below the select box.
i want to do this. But i do not know how i can do this . I think for this i have to onchange event in select box .But in correct way i do not know how it is possible.
I am trying to extract the value from a selected item in a Select/Option, parse it server side using asp and then populate a text box on the same page with the value that was parsed. simple example below:
Two problems I have here:
1. The code: this.frmEditUser.Submit; does not appear to submit the form. 2. If I submit the form using the Submit button, it works except I get:
Currently I am using an onchange event on a select menu and it is working fine. But if the user uses any arrow keys the event will not trigger. Is there any way to do that?
For some reason my change() function is only called when the page loads. I'd much rather it gets called when the select changes.
Here's the code:
window.onload = init;
function init() { var new_select = new Selector('tdata','myselect','myid'); var new_select_list = new DataSource("some_list"); new_select_list.addItem(1,"One"); new_select_list.addItem(2,"Two"); new_select_list.addItem(3,"Three"); new_select_list.addItem(4,"Four"); new_select_list.addItem(5,"Five"); new_select.setDataSource(new_select_list); new_select.formInput("form","input"); }
In a <select> drop-down, the onchange event isn't called when scrolling through the dropdown using the mouse-wheel and when crossing over a new <optgroup>.
Using the example below, notice how the onchange event isn't called when mouse wheel scrolling between A3 and B1, but it works properly when scrolling between A1 and A2.
E.g. ------------------------------------------ <html> <body onload="document.forms['myForm'].elements['mySelect'].focus()">
I have a table that contains a select element like so
<tr><td>key value in hidden input</td><td><select>options</select></ td></tr> I need to set $("selectclass").change(function() { //Find the value of hidden input in 1st cell of row of the select list that was changed. });
So when a user changes the option of the select i need to get the new value the option has been changed to plus the value from the hidden input and submit them via ajax to a method on the server. How can i get the hidden inputs value?
I have problem with event listening in CKEditor. I searched these forums for answer, but I didnt found it. I need someting like "onkeypress" on textarea for CKEditor. If I think well, I can must use "DOM" of CKEditor, because it is not simple textarea - but I am lost here. I really dont know how to do it. I need simple draft saver - onkeypress will launch a function which will check if timer is on. If yes, return false. If no, use ajax to save content of textarea.
I'm currently facing a weird issue with the onchange event. I have a web application where each blur event makes a call the webserver to store the value of the textfield. I only want to trigger that ajax call when something has changed, so i track the onchange event on each textfield to set a flag if something has changed.
The onchange event always fires to first time when i click outside of a textfield even if i didn't change anything in the field.
I narrowed it down to the following: A prefilled textfield always fires the onchange-event the first time you leave the textfield. An initially empty textfield does not fire the onchange event.
OnChange, I want to invoke a function that auto populates the rest of the SELECT fields in the form. The select boxes will vary in quantity as the page is dynamic, but the values are always the same (like the code above).
i need to display selected item from dropdown menu into text box. what i want to do is when user select the item it will display on textbox call programme (java script) and also when button search is click it will display the total number of particular programme (php). for now, selected programme is function but the other one is not.
I have 2 dropdown lists which are connected to a mysql database. When I select an item from the first dropdown list the second dropdown list should show item which are linked to the item from the first list. But the thing is I can select an item from the first one, but the second isn't showing anything.
In the mysql database I have 2 tables: hesk_programma and hesk_projecten. In table hesk_programma there are a ProgrammaID and Programma column. In table hesk_projecten there are a ProgrammaID, a ProjectNumber and a Project column.
ProgrammaID from the two tables are connected to each other, so when I select an item from the first dropdown list with the ProgrammaID AK, the second dropdownlist should only display the items with the ProgammaID AK from the hesk_projecten.
By the way, one more thing. The ProjectNumber from the hesk_projecten table should be displayed (when selecting an item in the second dropdownlist) in a input text field.
Is there anyway to trigger an onChange event without actually clicking etc.
I want to trigger it from a method. It sounds silly but I'm taking some code over from another developer and if I could do this it would save me days of re-writing!!!
Ive searched this forum for a simple solution to this. I want have a drop down of countries. Only if USA is selected, it shows states, otherwise it is hidden. I have a function which is 'trying' to write the state dropdown to an empty span.
According to [URL] intended way for jQuery to change dynamically the selected option of a dropdown select control isassigningthe desired text instead of the value. I found this way veryinconvenient (data structures usually deal with value codes, not value descriptions) and it seems to work only sometimes.
Trying different options I came out with this approach that seems to do the job so far:
function setSelect(pID,pSelectedValue) { $('#'+pID + ' option:selected').removeAttr('selected');
How can I change a select list when a user enters a value into a text box? Like with the below form I would like to have the select box change when the user enters a value in the "id" text box that matches a value in the select box. Say the user types "1122" in the text box I would like the select list to change to to show "John". Is this possible ....
