Mixing PHP And Simulate OnClick?
Jun 15, 2009
I have a onClick event in Javascript, What I would like to do is if a PHP variable were to be set, to trigger the Javascript onClick event. Is there a way to simulate an onClick? [URL]I have a form with some non-showing (non hidden) input fields but they show if I click a + and hide if I click -, default is hide, but if a certain PHP var were set I want to somehow simulate that + was clicked. I tried to force 'var lText' but that got the whole thing stuck in one state.

I have a dropdown list:
<select name="select" class="mapMenu" onChange="JumpToIt(this)">
<option selected value="none">Select a Tool --</option>
<option value="javascript:onCreatePrintable()">Print Map</option>
<option value="javascript:onFindLatLong()">Find Lat/Long</option>
</select>
That calls a script:
<SCRIPT LANGUAGE="JavaScript">
<!--
function JumpToIt(list) {
var newPage = list.options[list.selectedIndex].value
if (newPage != "None") {
location.href=newPage
}
}
//-->
</SCRIPT>
Which in turn selects an option from the original dropdown.
Works fine except.....
The options in the select call scripts that open new browser windows,
and when this occurs popup blockers swing into action and block the new
window. When I originally had the javascript calls as plain links such
as [HREF="javascript:onCreatePrintable()"] the popup was not blocked
since it was obvious that user was clicking the link. Now that I'm
trying to save much needed space by putting these links into a
dropdown, the popup blockers are not recognizing the user selection....
I guess. I was thinking the javascript could somehow simulate an
onClick to alleviate the problem. Any suggestions?

Many modern libraries implement this type of function (I know prototype does), but it's a great one to have in your common.js in case you don't need a full library for projects.
The basic idea is that using .innerHTML to insert new elements is very convenient because you can simply provide a string of the new HTML, but you lose the precision of DOM insertion (for instance, if you want to insert a new element in the middle of a bunch of DOM siblings, you have to replace them all in the parents innerHTML).
Conversely, using DOM methods like insertBefore() are very precise but require you to make the entire structure with createElement calls. This can be a LOT of code when all you want to do is insert a new anchor element.
This elegant little solution combines both methods by riding on the fact than when you replace an element's innerHTML, the browser creates the appropriate DOM hierarchy for the new elements on the fly. So this function takes a string of HTML you want to make into a DOM structure, changes the innerHTML of a dummy element to render this structure, and then returns the first child.
// fromHTML()
function fromHTML(html) {
var root = document.createElement(‘div’);
root.innerHTML = html;
return root.firstChild;
}
Very simple to use, and very handy:
var node = fromHTML(’<a href=”home.html” title=”Going Home”>
<strong>There’s no place like it</strong></a>’);
// Now you can use the precision of DOM methods without having
// to create the entire structure by hand:
element.insertBefore(thing, node);

I have two jQuery scripts running on the same page. One of them dynamically assigns height parameters to the wordpress page. The other is a slideshow script which makes images transition from one to the next in a slideshow.When the slideshow is inserted into the wordpress page, it works fine, but in IE7 there is extra page height whenever there is a slideshow on the page. In other browsers it is fine, and on other pages that dont have a slideshow the page height is fine.Looking at the source code, it seems that the dynamically assigned div height paramaters that are injected into the slideshow divs by the jQuery slideshow script are getting involved in other divs on the page, influencing their height.It seems that the slideshow script is interfering with the page height script. how can I make it so they dont entangle? Here is the page height jQuery script that assigned dynamic height to the "art-content-layout-row" div (the div that controls page height)
Code:
/* begin Layout */
jQuery(function () {
if (!jQuery.browser.msie || parseInt(jQuery.browser.version) > 7) return;
[code]...
When looking at the html source in the page, the slideshow script inserts this jQuery unique number beside the dynamically added div parameters in the slideshow divs like this:
cyclew="666" cycleh="555" jQuery="130236363678267"
It turns out that this same unique number is assigning itself to the art-content-layout-row div which is supposed to be controlled by the other script.I am wondering if the fact that these unique id numbers being the same is causing the issue, as though the system is thinking that these two scripts are somehow the same one?Both scripts are in different directories and called separately in the page footer.

Is it possible to have secured (SSL/HTTPS) and non-secured (HTTP)
content in the same page without breaking the security? I am developing
a secured reservation system in which the user can access Google Maps
(not secured). The map is embedded in the page and does not open in a
separate window.
What solution do you recommend? Use iframes? If so, how?

How do I simulate a ESC key without user intervention? For example I want the ESC key be executed in the background when a page loads or a user clicks on a link? Is it possible in jQuery?
I know there are ways to validate what key was pressed on the keyboard using .keypress but I am looking for something like 'SENDKEYS'

this is a bookmarklet for IE that I use to see how a page works with different widths (i.e. you can simulate 1280x1024 or 640x480) without need to change resolutions or adjust window size. Not 100% accurate, but it's enough:
javascript:db=document.body;bst=db.style.zoom=1;resdesti=prompt("Destination:",800); db.style.zoom=db.offsetWidth/resdesti;void('')

I'v created a site for client, with several pages of products for
sale, we're not using any Online payment method yet -so in the
meantime, I'v just provided an Order Form, to be completed, printed
then mailed off with payment....
what I would really like to do, to improve this greatly - would be to
simulate what a paypal "add to cart" button would do - which is click
to add an item, and it places that item in a window in a separate page~
just as paypal does, and so on as they click on any other product to
buy, this would then give them an order form - but just containing the
items they want to buy - instead of the present order form which has
all products from that catagory, but obviously has the ones wanted
marked.

1) I would like to click the Download button on this site, then wait lets say 60 sec & click free download button.[URL].. I remember that somehow it is possible to create the Request URL & then input it into IE & the server will think I hit the button.
But how can I make the URL? And how is it called? posting URL request? I will be using firefox or I can make HTML file & execute it in IE for every file.
<form action="http://uploading.com/files/get/S4WYPP73/" method="post" id="downloadform">
<input type="hidden" name="action" value="second_page" />
<input type="hidden" name="file_id" value="4663720" />
function do_step_1()
{
do_request('files', 'get', {file_id: 4663720, action: 'step_1'}, function(wait_time){
if(wait_time > 0)
[Code]...

I've search all over to find a way to simulate an actual click on an element using javascript or jquery.
For example, suppose there is an element with id="someElement". I've tried
$('#someElement').click();
and
$('#someElement').trigger('click');
But this doesn't work. You might think "Why don't you just call the function that is triggered by the click event, or redirect to the url that a click would lead to anyway", but I can't do this.

Since browsershots/org only gives static images of a web page, would it be possible to attribute e.g. the hover state / the focus state to a link via Javascript, in order to check via browsershots whether the hover or focus states are actually working as planned in a particular browser? Pardon my ignorance if this is impossible...

After all, there is some difference in the way we 'click' using our mouse at some place in the document, and what can be achieved by the dispatchEvent "click" in Firefox. We have a page, which has two iFrames on whole. Left frame having a table of clickable email subjects, and right frame showing the entire body of the selected email. The problem is, the clickable area on the subject is too small, making it a pain to click each email to see its body. So I implemented a way of navigating through them using keyboard in the parent page(using key handlers in Javascript). The problem is, when we load the page for first, the navigation works fine, since the focus is on the parent page. But as soon as someone clicks on any area on the two iFrames, the key handlers don't work because they are in the parent page, not in that frame.
I noticed that when I click on any area outside the two frames, it works again. Idea : "Why not do a setTimeOut or setInterval sort of thing, which just sits and keeps on clicking on a place outside the frames"? Good idea, but doesn't work. Why? Is installing the same kind of key handlers in both the frames the only other way? Even setting focus on an element on the parent page doesn't work.

I'm trying to change the value of an input field (target) which depends on another input (source). It works well when I manually change the source value. But if I changed the source value with another button, the target value remains the same.
Here's the code...
$(document).ready(function() {
$('input#change').click(function() {
$('input#source').attr('value', 'This is the value changed by a
button');
[Code].....
So how could the target input detect if there's a change within the source input without manually changing it's value?

I have been trying to merge two command scripts, and have gotten nothing. I am trying to use javascript commands to open a new window on Firefox, and on that opened window simulate a Tab key press.
This is the full script that I have come up with so far to open two windows, with the websites being yahoo.com and google.com. ***To fully help me please copy this script, paste to Notepad, save as a .html file and run it on Firefox. You will notice a "Open Windows" button will appear. When you click on it the windows will open:
<html>
<head>
<script type="text/javascript">
function open_win() {
window.open("http://yahoo.com", "newwindow1")
window.open("http://google.com", "newwindow2")
[Code]...
What I want to do is merge these two scripts, so that when I press that "Open Windows" button, the new window opens and the Tab key press is immediately simulated to move to the next field on the webpage.
I understand that JavaScript is event driven, meaning some event has to occur before you can make things happen. The user must push a key or click somewhere on the page before you can relaly do anything with an event. I want to have the clicking of the "Open Windows" button, that first triggering event which opens a window and simulates the tab key press on that window.

I'm designing a website for a mock promotions firm, and currently I have a header, menu-bar (horizontal, sits under the header), a big 'content' main area, and a footer, all arranged in CSS. The problem I'm having, is that I've got an embedded music player in the footer - and now obviously whenever I click on a link in the menu bar to take me to another page, the music re-starts, and looks very unproffessional The header, menu, footer and music parts are the same for every page, so I thought I could just use
document.getElementById("content").innerHTML = "[page code here";
as a JS function mapped to "onclick" of the links in the menu bar. It works for little quick practices, where I put text in the [page code here] for each different page - but here's the crux of the problem: One of the pages has an embedded flash file, a photo-gallery viewer. Here is the code for the 'content' part of this gallery page:
<div id="flashcontent">
You don't seem to have flash installed. <a href="http://www.macromedia.com/go/getflashplayer/">Get It.</a></div>
<script type="text/javascript">
[code].....
I uploaded this onto the webserver and gave it a go - the best I got was a dark box showing up (same colour as the photo gallery background) - Is it because I can't just lump all of that code into a getElementById call ?
