Javascript With ASP Button
Jul 20, 2005
I am trying to call this Javascript function:
function ButtonClicked()
{
alert("The button has been clicked.");
}
Calling it from an HTML button is no problem at all. But there is no way I can call that function from an ASP button. I tried from the HTML side or the aspx side.
I understood that an ASP button run only on the server. But I can't believe you can't make that simple call. I really hate to use HTML button when the design with ASP on a Web Form is so fast and easy.
Since I am a newbie, some code example will be appreciated.
Briefly, I have an ASP button that I want to call the Javascript function "ButtonClicked"

I am quite new to Javascript, but not new to programming in general or to (X)HTML.
Using events, is it possible to redirect someone to a new page? So if
you lined up five buttons, you could use this as your page's navigation
bar?

I am a novice with both asp and javascript so I may not even be
doing this correctly, but I have an asp page that has variable being
passed to it and I have a button that I need to have it go to one page
if it is one variable and another if it was the other variable. There
is only two choices but my attempts didnt work.

I am doing a javascript back button within my form
<input type=submit value="Back to previous page" class=header onClick="history.go(-1)">
for some reason it is submitting the form instead of going back a page --
why would this be?

Here's the script section:
function change(color){
var el=event.srcElement
if (el.tagName=="INPUT"&&el.type=="button")
event.srcElement.style.backgroundColor=color
}
function jumpto2(url){
window.location=url
}
if the form uses a type=button when kyou rollover the button it changes
form onMouseover="change(ྒྷcefa')" onMouseout="change('d3d3d3')"
input type="button" value="Hosting " class="color2"
onClick="jumpto2('hosting.html')"
however if the input type is submit instead of button when the button is
rolled over it does not change color here is what I mean:
form action="processLogin.jsp" method="post" onMouseover="change(ྒྷcefa')"
onMouseout="change('d3d3d3')"
input type="text" name="userName"
INPUT TYPE="submit" value="Login" class="color2"
My question is if the method is post and the input type is submit anyway to
make it rollover? if not what would a javascript look like that would use
the post method?

I do not know much about javascript, so please excuse me if my question is
not clear:
If I build a string in Javascript
string = "http://test_server_a.some_domain.org"+download_trial_of_product.exe
Then use
document.location.href=string
It works in Firefox, the popup box says,. would you like to download this
file... and the download is what its supposed to be. However, it does not
work well in IE. All I get is a nasty pop-up box talking about downloading
an Object. What am I doing wrong?

I have a 3-state rollover: home.gif, homeover.gif, and homeclick.gif
I would like to make the homeclick image be selected when going to the page it pertains to.
The way I'm doing it now, is I'm just changing the image for that particular page, to homeclick instead of home.gif, but I know there's a better way, isn't there?

I have a form with the following drop down
<select name="option" onChange="nav(this);">
<option value="">----------------</option>
<option value="copyfile">Copy</option>
<option value="renamefile">Rename</option>
......yadda yadda.....
</select>
Im wanting a certain submit a certain input button (I have several different ones in one form) depending on which drop down item they select.
So if they select Copy. I would want the javascript function to basically act like <input type="submit" name="copyfile" /> was clicked, and similarly if Rename was clicked, I would like it to act as if <input type="submit" name="rename" /> was submitted.

I have a page where users can filter a list of links using javascript clicks. The user then clicks a link in that list, views the page and then clicks back on the browser to view the rest of the list but the javascript options they filtered in the list are gone resulting in them having to do it all over again. Is there a solution to this?
Would it work if I store their selections in a cookie each time they click a javascript button and then when they visit a link and click back (to what is presumably now a cached page) will I be able to have javascript that will read the cookie and reset their options again or is the cookie not loaded on a cached page?
Are there any common solutions to this kind of thing?

What I want to do is create a button, that when pressed, closes the window
it is in, and launches a URL. The window the button is in is actually just
a sub-page of the main website page, launched with target="blank", but I
just do not want to close the window as I said, I want to launch a website
address from it & have the launched from window close.
So please, walk me through this. Where do I place the:
<SCRIPT language="JavaScript"> ?
(Oh - this is thr right way, correct - case sensitive, right?)
Then what? I can create a button with the tutorials, but if you know, just
write the darned thing for me please - I learned HTML mostly from
copy/pasting.
AND... OK, now more complicated maybe (???). Actually this is more
important than the above. This is from an application sub-page, the page
opening with target="_blank". So the below is HTML that creates buttons.
If the applicant presses the "submit application" button, at least when I
press it, it launches O.E. and asks me if I want to send the filled-in text
through O.E. to the email recipient. You know what I mean, right ? Well,
I want the window the "submit application" button is in to do it's thing all
right - submitting through the email, but I also want the page or window
(I.E. or other?) launched from to close also.
the HTML code that shows two buttons:
<input type="submit" value="submit application">
<input type="reset" value="start over"/><br>
Thanks for your input. Assume I know nothing about javascript, but can get
around in HTML.

I created a "cancel" button for my form at the clients' request, I
accidentally copied a submit button and added an OnClick event- a very
simple javascript.history function. It did not appear to work at all-
it kept submitting the form. I changed the submit button to a plain
old button and it worked fine.
Can anyone explain how the browser works with a javascript onClick
event ona submit button? Does it automatically submit the form no
matter what onClick event you use?

I am trying to move some text by clicking a button. When clicked the button
runs the java script and this will then take the value in the text field and
add 10 to it to create a new value, this is then used to move the text
(id=h1) to a new position and to display the new value in a text field. My
script is below but does not work. Im new to javascrip and there is probably
something embarasingly obviour that Im missing. Code:

I took over management of an established website that I discovered was
written in php and javascript (I am only familiar with html).
I needed to add in a new button so I looked at the code, copied the
code and pasted for the button above and typed over it the names of
the gifs and gave it a new button number. I found another place in the
code that appeared to relate so I did the same there too.
After uploading I tested my new button, it worked, so I deleted the
original copy I had made of the page.....
Problem was the new button is now the only one that works and I have
no idea how to undo what I did to make it work again.

Okay, so I've just installed a javascript that redirects to any random page from a specified list. The problem with it is, it's in an iframe and works as sort of an advertising area. So on the mainpage where the iframe has been placed, whenever someone uses the back button, it just keep going back in the iframe and choosing random pages. The back button doesn't work on the mainpage and instead is used in the actual iframe.
I'm not sure if this is a problem with the iframe or the script, and I don't think I have the mental capacity to figure it out so I'd really value some help! Oh, and apparently the problem doesn't occur when using Firefox. Code:

I'm not what you would call naturally gifted with javascript (I use PHP mostly), so I hope this is an easy question for one of you....
I'm trying to create a HTML link that, when clicked, affects a pair of HTML radio buttons by moving the selection from one radio button to the other.
the following code is wrong, but It's all mine, and its what I've written in a feeble attempt to accomplish this:
<HTML>
<HEAD>
<TITLE></TITLE>
<script type='text/javascript'>
<!--
function rejectAll()
{
if (window.document.link_form.a0.checked == 1)
{
window.document.link_form.a0.checked = -1;
}
}
-->
</script>
</HEAD>
<BODY>
<form action='file.php' method='post' name='link_form'>
<input type='radio' name='a0' value=Ƈ' checked>
<input type='radio' name='a0' value='-1'>
</form>
<a href='javascript: void(0)' onClick='rejectAll();'>Reject All</a>
</BODY>
</HTML>
Can anyone see what I'm trying to do here and point me in the right direction...

I have this PHP page that has the following functions...Insert Form into Table in MySQL DatabaseDelete Entry from Table in MySQL DatabaseA Link to a separate page where I Edit entries I have coded a PHP function for Delete. Looks like this:
// delete if provided if (isset($_GET['id'])) { // query to delete $query = "delete from student where STUDENT_ID =".$_GET['id']; //execute query if ($db->query($query)) {
Somewhere else I query the results and print them into a table. I added a column to this table with a Delete link for each row. Clicking on delete will execute the PHP function to delete.
The link looks like this: PHP Code:
echo "<td><a href=".$_SERVER['PHP_SELF']."?id=".$row[0]."></a></td>";
Likewise the first names also have links when clicked bring the user to another page with a form to edit form data.
The link looks like this: PHP Code:
echo "<td><a href='editstudent.php?id=".$row[0]."'>".$row[1]."</a></td>";
From here however I need to change those links to Buttons. One for Delete and another for Edit and use JavaScript functions to make them work as they originally did. So this is what I've done...
<td><form name='myform1'><input type='button' name='edit' value='Edit'
<td><form name='myform2'><input type='button' name='delete' value='Delete'
Next I need to write functions...this is where I am lost. Usually I'd know what to do when referencing elements in forms, i'd do something like document.formname.inputname, but my problem is those links or should I call them actions are replaced by those new buttons.
Should I put them into a form, or make them hidden, and then name the element? Or should my function look something like this...all I really want to do is to call the function, and have the function just do the action of loading the link (don't know if that sounds clear). I've tried to do this but it does not work.
<script>
function Delete()
{
document.myform2.action="href='$_SERVER['PHP_SELF']."?id=".$row[0]'";
document.myform2.submit();
}
</script>
Can anyone tell me what i am doing wrong, and could you please point me in the right direction?

Basically, I have a page that I load with 10 input fields. If users
have JS enabled I want to hide 5 of these fields so as to reduce
clutter. If the user needs these extra fields an "Add" button can be
used to display the hidden fields one by one.
Once the fields a filled in the user submits them for validation and
if there are any error They can "Go back" to make some changes. The
whole process works great in FF & Opera but IE lets me down because if
you use the Browser "Back" button the Javavscript gets executed even
though it should be loaded out of cache.

I am new to JavaScript and have been plugging away at it trying build a menu for site I am developing. My colleague has suggested I use Flash, which I could, but I think it is unnecessary and JavaScript is ideal for this use.
I have been building a menu that has a sub menu that appears below all of the main menu items. I have got this working and will include the code I used to do this below.
Now I want to change the button image so that it is visible which sub-menu the items that appear below belong to. Code:
which was very helpful and with some playing around I can now get my existing menu to complete part of my task. But I have 4 menu items and therefore need to use a "var" command to allow me to define different button images for different menus. Code:

In one of my pages, I use javascript (AJAX) to populate one mulitple
select field based on user's click event on another control. I noticed
that when I navigate back to this page by clicking browser's "Back"
button, the changes made to the multiple select is not preserved. (It
shows the initial value). While all the other user selections are
preserved.

This is hard to explain but here's my predicament. I have 2 drop down menus in a form for "Main Category" and "Restaurant Type". My boss wants it so when Restaurant is chosen from the first drop down, the 2nd drop down appears, which is what this code below is already doing.
The problem is if you submit the form, then decide to go back and change your Restaurant type, the drop down for Restaurant Type is missing. You can get it to come back by switching to another main category, then switching back to Restaurant. Code:

I am trying to produce a web form to allow wedding guests to RSVP. The form allows them to enter a name and select from a radio button whether they will be attending or not. If they select the "yes" radio button then a further pair of radio buttons are displayed for their meal preference.
They can then click a submit button or they can click another button to add another line for another guest which operates in exactly the same way. I've almost got this working, but it seems that the checkbox change handler is lost for the current guest when a new guest is added and the checkbox value is reset. I've got a feeling I'm doing something stupid but can't for the life of me figure out what.
Code (source file (renamed to .txt) also attached as I'm not sure the pasted code is too clear):
