OnChange Event Extracting Value From Select Incorrectly
Jul 23, 2005
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:
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.
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?
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
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 two links,i left the second one alone so you can see what result i want. but the first link is where i am attempting to remove the inline event handler (onclick) but i want the same result.
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).
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!!!
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 ....
In JavaScripts checks for an onChange event against the value of the textbox at the time of the last onChange event. Since an onChange Event never fired after you changed the text first time , suppose we put the same value in the text box then no event is fired.
If we put some other value then it became fired... It wouldn't fire if we put the same value...
I don't want to use onBlur etc... Isthere any solution with onChange Event...?
I Have a text box in a jsp that is pre populated. The text box should accept only numbers and it should be greater than a minimum value (this value depends on the user settings). If the user enters a value less than the minimum value, i should pop up an alert saying that the value entered is incorrect and reset it back to previous correct value. How could i do it using onchange event of the text box.
Am I right in assuming that you can NOT set focus() back to a field in its onChange event? Is there another way - I have validation that I would like to set the focus back to the invalid field onChange?
I'm trying to get a tick box to tick automatically when the user changes the textfield called comm. my code is below but it doesnt work. Can anyone see why?
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.
So what I need to happen, is based on the selection of the first selection box, some of the options of the other selection boxes should not be available.If Outside is selected, everything in LocA should be available, but only up to 4 in Loc1... and if Inside is selected, only up to E should be available in LocA and everything should be available in Loc1.
