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:
Here is the html:
<select name="activities_limit" id="activities_limit">
<option value="5" selected="selected">5</option>
<option value="7">7</option>
<option value="10">10</option>
<option value="14">14</option>
</select>
And the jQuery:
$("#activities_limit").bind("change", function() { alert("value changed"); });
I am not seeing the JavaScript alert though.
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?
View 4 Replies View RelatedI 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");
}
Selector = function(container_id,name,id) {
var container = document.getElementById(container_id);
this.node = document.createElement("select");
//this.node = new Select();
container.appendChild(this.node);
this.node.name = name;
this.node.id = id;
}
Selector.prototype.setDataSource = function(ds) {
this.dataSource = ds;
for(var i = 0; i < ds.items.length; i++) {
if(ds.items[i] != undefined) {
var option = new Option(ds.items[i],i,false,false);
this.node.options[this.node.options.length] = option;
}
}
}
Selector.prototype.formInput = function(form,element) {
var myform = document.getElementById(form);
this.input = document.createElement("input");
this.input.name = element;
//this.input.type = "hidden";
myform.insertBefore(this.input,myform.firstChild);
this.node.onchange = change(this);
}
function change(selector) {
alert("hello");
selector.input.value = selector.node.value;
}
DataSource = function(name) {
this.name = name;
this.items = new Array();
}
DataSource.prototype.addItem = function(id,item) {
this.items[id] = item;
}
and the html:
<html>
<head>
<script defer src="/javascript/selectors.js"
type="text/javascript"></script>
</head>
<body>
<form id=form>
<table border=1>
<tr>
<td>
Select:
</td>
<td id=tdata>
</td>
</tr>
</table>
</form>
</body>
</html>
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()">
<form name="myForm" id="myForm">
<select onchange="alert('onchange event');" name="mySelect"
id="mySelect">
<optgroup label="Group A">
<option value="A1">A1</option>
<option value="A2">A2</option>
<option value="A3">A3</option>
</optgroup>
<optgroup label="Group B">
<option value="B1">B1</option>
<option value="B2">B2</option>
<option value="B3">B3</option>
</optgroup>
<optgroup label="Group C">
<option value="C1">C1</option>
<option value="C2">C2</option>
<option value="C3">C3</option>
</optgroup>
</select>
</form>
</body>
</html>

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'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.
Sample code (IE 8 on Windows 7 computer):
script:
HTML:
I searched here and some other places on the net but cant find anything that suits my needs. I have a SELECT box with 3 values Code:
<form name="form1">
<select name="length">
<option name="length" value="none">--Select for All--</option>
<option name="length" value="5">--5 Days--</option>
<option name="length" value="7">--7 Days--</option>
<option name="length" value="10">--10 Days--</option>
</select>
</form>
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).
Does this make sense?
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 ....
View 5 Replies View RelatedI have an array with mysql´s data. I have used this array with several text
box in a formulary.
My question is: How could i use the event onchange to make a function which
update the data of array when i would have change data in a text box.?
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?
Eg:
<input type=text" name="tstfld" onChange="window.alert('Changed!');
this.focus()">
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?
function changed(x)
{
document.getElementById(x).checked;
}
<input name="changed" id="ischanged" type="checkbox" value="">
<textarea name="comm[]" rows="2" class="BodyText" style="WIDTH: 99%"
onChange="changed(ischanged)"><?php echo stripslashes($comment);
?>
</textarea>

I would like to use some event handling on a form, not something I have done before and looking for some assistance. Here is my code:
<select name="LocO">
<option value=""></option>
<option value="O">Outside</option>
[code]....
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.
I would like to have a dropdown to only show when a certain value is chosen from another drop down.
So if in this dropdown the value ETS Rep Discount is chosen he should show the other dropdown
<div class="row">
<div class="fieldName">Discount Type</div>
<div class="fieldValue">
<asp:DropDownList ID="discountTypeDropDownList" runat="server" AutoPostBack="True"
Width="295px"

IS there a way to trigger an onchange event from a DIV,eg, I have a DIV like this

so, when i change the content on this DIV using

for some reason the onchange event does not get called in the following code:

I'm having some difficulty in accessing an 'external' function from my onchange event. It will work when the function is included 'inline,' but it's not working when the function is 'stand alone.'Additionally, when it works, the variable isn't being passed - the alert I use says "[object Event]"
Code:
<head>
function nameTextBox2(selectBoxName)
