Onclick Defined Variable - Print Variable Some Place In Document
May 28, 2007i'm not really sure how to explain this, since I know nothing about javascript, so i'll try and illustrate by the use of php (hope it makes sence)
I have a set of different links, like:
<a href="link.com?page=text1">text 1</a>
<a href="link.com?page=text2">text 2</a>
<a href="link.com?page=text3">text 3</a>
etc, where page is dynamic and can be anything I chose..
Another place in the same document, I echo out what the page variable is, like:
echo "$page";
so when clicking "text 1" the echo will output what i've defined the page to be, in this case "text1" ..
So I want to be able to click the links and change the output of the echo all depending on what i've defined in the link - without refreshing the page!
Is there any easy way to do this?

Passing Variable In Onclick?
Apr 2, 2009Basically, I have a form with some text fields, and I want to put a button next to each text field, so that when a user clicks on the button, it increments the value in the field by 1. I know how to do it if I know the id of the text field, but what if the id of the text field is a variable? How do I do it? Here's my code:
<script language=javascript>
function process(v){
document.getElementById('order_item' + v + '_quantity').value++;
[code]....
My issue is with my onclick statement:
<input type="button" value="Add +" onclick="javascript:process(0)">
This works fine for my first field, but I need to have one for every text field, so how do I pass my counter variable (which determines the id of the appropriate text field) to the process function?

Changing Variable Value With OnClick?
Nov 13, 2011I am building a site where I want all links to partial page reload using xmlhttprequest and innerhtml. I have done this before, butI always had to have a seperate xmlhttprequest function for each link. So this time I am trying to write just one function, and have the onClick change which document the request is getting. It is not working and I appear to novice to figure out why. Here is the code, i have bolded some relevant lines:
<script type="text/javascript">
function ChangeContent()
{
var whichPHP;
[Code]....
Also, if I use the innerhtml function to write another of these hrefs, will that link be able to access the function if it is in the header, or should I put the entire function in a .js file on the server? The point of all this would be that the entire page never reloads and all the text content is swapped out on demand.
Url Variable To Onclick - Can't Get The Next Page To Load
Sep 22, 2009I am trying to use an onclick statement to go to an alternate web page displaying a different version of tha file being displayed in the current page.

I have tried every combination I can think of in the onclick code to get it to work but, no joy. here is an example:
I just can't get the next page to load.

OnClick, Create Php Variable And Echo Out
Sep 27, 2010I have a form, that when the user click Submit, I need a php variable to be echoed to the page. This is for an upload page. So when they are waiting for the file to upload, it will say "Uploading..." until the upload is complete.
All I know so far is I need to create a javascript function and include it in the submit button. This is all I have so far in the submit button tag:
onClick="Transferring();"

Variable Scope In Onclick Event
Oct 17, 2010I have this web application where users are able to fill out and submit reports. The reports and scripts are part of a whole system, that is, they are used on a couple of different clients written in both vb and c#. This is the web-version of those clients.The scripting language is javascript and is executed using different script engines on the different systems. But for the web-version it is just executed in the browser.The different fields in the report can be accessed by typing:ID1.value. To get ID1 to apply for the input-field with id ID1 I had to in the initfunction of the page write a window["ID1"] = document.getElementById("ID1");
But my problem is when this element change. Cause in the report I have a special element that in the browser is translated to a table-element with a report-field in each cell.When I switch the current row, I need to update the window["ID1"] to equal the correct report field on the selected row. But when trying to access the new variable ID1 from a buttons onclick event it is undefined.<input type="text" id="test" onclick="alert(ID1.value);" />What I think happens is that when the page is first drawn the onclick event is created and as I understand, variables inside an event has the same value as when the event was created.
So if ID1.value was something when the page was created it will be the same when it is called even if the value of ID1 is different. And that seems to be the case. When I debug the page, before entering the event, ID1.value has the correct value while inside the event it is undefined and after the event it has the correct value. If I write window["ID1"] correct value is also shown.But a weird thing is that in another place in the code I had the same problem but instead of having the code inside the onclick event I first had a global function changeActiveRow and inside that I had an eval, eval(document.getElementById("ID1_script")) where ID1_script is a hidden element whos value is a script using ID1.value and that works.
Retrieving A Variable And Then Incrementing And Displaying Onclick?
Feb 10, 2010Simply put, I need to take a variable (The number '20' in this case) that is displayed by an input box on my web page and plug it into a function so that whenever I click on a button, the number in the input box will decrease by 1.
Seems simple enough, though for hours I've been going at it with no luck. Skipping the rest of my code - I currently have:
<head>
<title> Online Slots </title>
<script type="text/javascript"
src="http://dave-reed.com/book/random.js">
[Code].....
The entire code is a slot machine project that's supposed to be extremely simple where you hit the button and it spins 3 wheels, 3 of the same image and you win. Every spin takes $1, every win gives $13.
The majority of the code is already working, however for some reason I appear to be failing badly at getting the read out to show a decrement of $1 every time you push the button.
I've tried so many different ideas that I've found across w3schools, webdevelopersnotes, dave-reed, ect - and so far I haven't been able to get any of them to work correctly.

Aug 6, 2010Below is the code that is using the name FFF in various places. The effect of all this is that the onclick function is not executed.

Setting Cookie OnClick, And Or Passing A Variable?
Sep 21, 2009I'm more of an actionscript person but got roped into an html/javascript job.What I need to do, and it shouldn't be that difficult is this:page1.html - there is a yellow button and a red button - if the user clicks on the yellow button I want to set a cookie with the value "yel" then load the next page - if they click the red button set that cookie with the value "red"page2.html - 'onload' i want to read that cookie and load up the main image to match, something like this maybe?... document.mainimage.src='img/main_' + variable + '.png'so that the path would be for example 'img/main_red.png'f you think this would be easier sending that variable in the URL instead of as a cookie please explain. I'm having a very hard time searching for tutorials that are any good and that do exactly this kind of thing.

OnClick Event Images Deliver A Variable To Another Page?
Sep 11, 2009I have a html page with a lot of thumbnails. The idea is that when the user clicks on an image the onClick event is to display another detailed form and deliver to that form the name of the image in a variable. In the detailed php-form there is a query to MySQL to retrieve a record. The record will be retrieved by a Query based on the name of the picture. Apparently the PHP cannot do the job. I had an idea to make the thumbnail page as a form and to use use a hidden field with the thummnail name which should be carried on with the $_POST array through the submit button but i do not want to have a submit button. The more elegant way is just by clicking the picture the detailed page is opened and the variable is transferred where my php code can make use of the variable for the query. I have never used java before so you have to excuse for the lack of knowledge.
View 3 Replies View RelatedOnclick Accordion Works In IE7 But Not IE8 (variable Is Null Or Not An Object)
Apr 28, 2010Hey all, I'm using a fairly simple accordion script. When I went to take a gander at the page in IE I found that the onclick function of the script doesn't respond. It works in FF, Safari, Chrome and Compatibility Mode in IE 8
the error message IE gives me is
Message: 'h' is null or not an object
Line: 13
Char: 77
Code: 0
URI: http://proposalfor.us/js/script.js
The problem line (as far as I can tell) is:
this.a[s]={}; this.a[s].h=h=T$$(e,v)[0]; this.a[s].c=c=T$$('div',v)[0]; h.onclick=new Function(this.n+'.pr(0,'+s+')');
Make An Onclick Event Change The Document.onclick ?
Sep 4, 2010I want to make it so that when I click on something, it changes what document.onclick does.
This is a simplified version of what I'm trying to do:
Code:
<div id="clickme" onclick="document.onclick = function(){ alert ('This should not be alerted on the first click'); }">Click here</div>
However, as you'll notice, the alert box shows up on the first click as well. The only way I have been able to get around this behaviour is to have the first onclick execute a timer that will then set the document.onclick after 1ms, however this seems very messy to me.

Oct 13, 2009a.) specify two parameters for the changeYear function: today and holiday.

b.) in the first line of the above function, use the getFullYear() date method to extract the 4-digit value from the today variable and store the value in a variable named year.

d.) in the third line, use a conditional operator on the year variable. The test condition is whether the value of the holiday date object is less than the today date object. If it is, this means that the event has already passed in the current year and the value of the year variable should be increased by 1.
