Creating Generic Javascript Functions (ie. El.onmouseclick = Function ...)

Jan 8, 2007

I want to learn more about creating functions for element events
without having to put onclick event in every tag. For example:

<script>
document.getElementsByTagName('input').onclick = function () {
alert('hello');
}
</script>

Now, I know the above does not work as I have tried it but hopefully
the idea of what I am trying to achieve here. Basically for every input
tag, when the user triggers the event (click) it will do the same
function.

Anyway, I would more so like to learn about this type of scripting
where you assign functions to events. However, I dont know what to
search for in google and the like. Where could I learn more about this?

JQuery :: Passing The Success Function Name Into A Generic Function?

Jan 6, 2012

I have a lot of similar instances of the following code on my page:

$('#btnEditParty').click(function () {
$.ajax({
type: "POST",
url: "WardAdmin.aspx/GetParty",

[Code]....

I'd like to create a generic function to save repeating a lot of code and then just pass in the relevant values.

I'm fine with that, the only thing I'm not sure about is if/how I can pass in a function name to be called on success/fail.

This post is where I was doing something similar to save repeated code: [URL]

In a similar way is there a way of passing in a function name to be called on success?

Creating Javascript Function To Swap Radio Values

Mar 1, 2006

i am having a problem creating a javascript function to swap my radio values based on the first set one.

i have a bunch of radio buttons on the page which are like this:

Code:
<input type="radio" name="add_id[1]" value="yes" CHECKED>Yes <input type="radio" name="add_id[1]" value="no">No
<input type="radio" name="add_id[2]" value="yes" CHECKED>Yes <input type="radio" name="add_id[2]" value="no">No

etc.... and each one is different, related to an input field, and as you can see it is a radio input array, and all radio inputs are named add_id[1], add_id[2], add_id[3] and so on i want a javascript function that will swap all the values of these radio buttons to whatever the first on is set to, either 'yes' or 'no' Code:

I want to write a generic clearForm function to clear the form when
the user click CLEAR button.

Here's my attempts, because I want to take care all html controls. I
think I need to test if the control is submit button, regular button. But I don't know
what I should do on drop down box?

function clearForm()
{var i=0;
for (i=0; i<InputForm.elements.length-1; i++)
{var obj = InputForm.elements[i];
document.write(obj.type); //runtime error: object doesn't support
this property or method
if (obj.type != "submit" && obj.type != "button")
obj.value = "";
}}

Creating Calculator Using AppendDigit And Else If Functions?

Oct 20, 2010

I am new to Java and my teacher goes way too fast in class and am a day behind on this calculator. Our assignment is to make a Calculator using AppendDigit and Else if functions in the java code. Some of my other code in html may be messed up as well. I am just lost so here is the HTML:

Code:
<title>John's Calculator</title>
<style type="text/css">
.rt {text-align:right; font-family: Courier New;}
.numbttn {text-align: center; background-color:
silver; font-family: Courier New; width 4eM;}
body {background-color: silver} .....

And Here is the pathetic Javascript which I have barely started:
Code:
// cal Applet- John Falco- 20 October 2010
function clear TB() {
document.form.kpd.display.value="0";
}
function AppendDigit (x) {
if (x==".") {
if ((!HasDecimal))
}
else {
document.forms.kpd.display.value =
document.forms.kdp.display.value + X;
};

Creating A M*n Table Using Functions And For Loops?

Oct 16, 2011

Write a script to generate two random numbers for variable m and n, the values generated for the variables should range from 1 to 10. We want to make an m * n table (m rows and n columns) with the word Hello in each of its cells. Now define a function f with one parameter n that displays n columns of one row of the table (You need a for-loop). Call this function m times to display m rows of the table. For example if m = 6 and n = 4 we should get the following:

HelloHelloHelloHello
HelloHelloHelloHello
HelloHelloHelloHello

[code]....

(The above is supposed to be a table but did not copy fully)This was my attempt, although i really did not know how to attack this.

<script type="text/javascript">
function f(n)
{

[code]...

Writing String Value To A Separate Iframe Using Onmouseclick

Sep 19, 2010

I am currently trying to create a simple form based web-page (uploaded here [URL] that creates a query for a WMS (Web Map Service).

The page consists of about 10 different forms, which are all put together in a (string) variable named "compiledQuery" in a function named "compileRequest" which is activated via a button. I would like to print out this variable on the page so that the users can see the query for themselves. After doing some research I came to the conclusion that the best way to do this would be via an iframe (I do not want to use a pop-up). The function I use to do this is:

function printRequest()
{
var query_frame = document.getElementById('frame_compiled');
query_frame.document.write(compiledQuery);
}
"frame_compiled" is the name of my iframe:
<iframe name="frame_compiled" width="400" height="125">
</iframe>

I know that "compiledQuery" has been assigned a value (I used an alert with the value). Hence, I also know that the "prinRequest"-function works on principle... However, it seems as if I am having problem with retrieving the name of the iframe to the function (I tried doing an alert with the value, it was returned as null).

So, I suppose my question is this: How do I properly retrieve the value of the iframe, and am I on the right way using document.write to show the value of "compiledQuery" to the users? Or should I use another way of doing this completely?

Javascript Functions

Jul 23, 2005

I am learning HTML for the first time taking a self teaching class
though my local Community College. Normally this college rocks and has
some of the best resources and down to earth teachers that pick books
that acutally help folks.

Well they failed and my book take more logic jumps that Stephen
Hawkins! :D

So my ultimate question is as follows:

How do I created a function with the following information provided:

Create a fucntion named Mquote that contains the single parameter,
Qnum.

My apologies for such little information. I am sure its my oversight
that I am unable to locate the answer to my question.

What I am looking for is the base layout for noob java functions.

Creating A Code Generator In Javascript - Is It Possible?

Feb 21, 2007

I have seen quite a few code generators over time where you are presented with a form, you fill in the various fields in the forum, and then click a Generate Code button, and the results show up in a textarea.

The code is then copied from the textarea and pasted into notepad or directly into an HTML document.

So, you may have some code that you want to generate that looks like this:

In this particular case there is 1 .js files that go to the root of the site that requires no editing.

Then there is 1 .css file that may require changes depending on user preferences. Things like margin, width, height, border and so on.

Then there is a section that goes into the Head of the document that requires no changes.

Then there is something like this would go inside a division"
<a href="address to a page" target="an iframe name"><img src="path to thumbnails/thumbnail name" border="1"></a>
Note that the above code has variable that would change based on user preferences. The way the code is presently structured it is not done as an array, however, this would substantially shorten the code depending on how many thumbnails are in it.

And finally there is another iframe section that would go inside a couple of a division. It relates to a second iframe.

Before I go any further with this, I just wanted to know if it's possible to do with javascript or is it best to do in another language.

The variables don't have to be kept in a database. What I am thinking is that the user would simply open up the HTML page, enter the data, generate the code, copy/paste and test, without closing the page. If there is a problem, he/she would simply go back in and change a variable or 2 and re-generate the code.

Calling Javascript Functions From Applet

Jul 23, 2005

We have an applet that has to support the SUN VMs as well as the MS VM.
The applet receives updates from a server (via tcp or http) and wraps them
up as objects and passes them using the JSObject scripting context to a
javascript function.

This function takes the object and reads the properties and updates a
screen.

All seems simple stuff. The problem is that the MS JVM runs like a rocket,
but the sun vm seems to max out our processor and also takes ages to process
anything.

I have tried logging from the console using debug level 5, and it shows a
lot of back and forth between the applet and the javascript when accessing
methods on the object passed.

Seeing that as a possible problem, I now pass a delimited string to the
front end, and then convert that into an update message purely in javascript
so there is only one hit to the applet per message.

I am still seeing a massive difference between the sun and ms VMs.

Has anyone ever come across this, and is there anything I can do to help
flatten out this performance?

Dynamically Adding Javascript Functions On The Fly?

Apr 1, 2006

Might there be a way to add a set of Javascript functions to a display page's existing set of Javascript functions on the fly without reloading the display page, and if so, how?

A couple of approaches I have tried, but without success are:

- A) For an embedded "retriever" IFrame in the display page to retrieve a set of JS functions from the server and then on its "onload" transfer (by innerHTML transference) that set of functions into the parent display page.

- B) Similiar to "A" but to use regular old browser frames - one being the "retriever" and one being the display page.

- C) Using a JS function in the display page to make a http request for a supplementary .js file(s).

Please note: the goal is to retrieve *only* an additional set of Javascript functions from the server, and then add them to an "original" set of functions already loaded into the browser. Meaning, NOT - say - for an IFrame to download from the server *both* the additional set and again the "original" set, which the parent display page could then run directly from the IFrame.

After "A", "B", and "C", I'm at a loss for further ideas.

On Click => Excecute 2 Javascript Functions

Dec 5, 2007

I have a form with 2 submit buttons, "Test" and "Save".

I also have to javascript functions, "TestImage" and "SaveImage".

What I want to do is, when the "Test" button get's clicked, then execute the "TestImage" function. That was easy, I did it like this:

<input type="submit" name="test" value="Test" onClick="return TestImage(this);">

But what I also want is, when someone clicks on the "Save" button, to first execute the "TestImage" function, and then the "SaveImage" function. Anyone know how I can do this?
