HTML Link That Calls Function?

Jun 14, 2010

I am currently trying to make an html link that will add elements (specifically, drop down menus) to the current page when you click it. Since I am adding all the elements to the page using JavaScript, I'm not sure how to set up the link to call a function rather than go to a different page. I've seen people set the href attribute to the function they want, so I tried that and it didn't work. I've also seen a way that involves using onclick and making the link follow the onclick, not go to a different page.

In summary, how do you create/edit a link (from javascript) to make it use a javascript function rather than go to a different page? This is what I have currently (that concerns the link):

var link = document.createElement('a');
eval("link.setAttribute('href', 'javascript:addHours(" + dayDiv + ")');");

JQuery :: Timing Not Quite Right - Hide() Function Calls Immediately Without Waiting For The Animate() Function To Run

Apr 1, 2010

I'm using jQuery 1.4 to hide a div (#cartPop) when the "close" link inside of it (#cartPop a) is clicked. Since I'm using animate() to fade the div out (opacity), I also have to use hide() to get rid of the div once it has faded out (otherwise the invisible div, which is on a higher z-index, blocks the elements on a lower z-index).

Code:

The problem is that the hide() function calls immediately without waiting for the animate() function to run. Even if I append a delay() function before hide() like so:

Code:

...it still doesn't wait.

Ajax :: Link Calls In Form, Forms Doesnt Submit?

Nov 3, 2011

This is a ? about Ajax, PHP and form processing. When I submit the form further below, nothing happens I didnt set the form-"action" to anything. I left it out, to make the form submit to the same page, so I can validate on the same page too (Which is not made yet, as youll see. The form does work fine when I used in a "normal php script", but when I include it using Ajax, the form doesnt submit after it has been sent to the page.

Anyone knows what is going on, and what I can do to make it work? I guess it must be the action attribute of the form which is wrong, but I dont understand that since i made the form submit to itself, by leaving out the action attribute entirely.

I have two links on a page, which calls a javascript function, opening a xmlhttprequest: I have only shown one of the forms, as they are almost similar, but there are two forms, in the real page, which displays depending on the link selected.

JQuery :: Prevent Multiple AJAX Calls From Button/link Push?

Sep 28, 2010

I am working on a project that relies heavily on AJAX calls, they are done in dozens of places. There are a number of places where I would want to prevent the user from submitting information multiple times (form submissions etc ). I am trying to think of the best way to accomplish this.

I could simply disable the element that starts the AJAX call upon the first click and re-enable it upon completion of the call. I have also seen examples of developers using a class to handle ajax calls that store an identifier for the call and if it is in progress any new calls with the same identifier will be ignored.

Maintaining State Between Function Calls

Jul 23, 2005

I would like to add dynamic text sizing to a website. There will be three text sizes. When the default is used, only the "Increase text size" button is shown. When the maximum size is used, only the "Decrease text size" button is shown. And otherwise, both buttons are shown.

I've been working on a mockup as follows at the end, but my issue is that once I have manipulated an element of the HTML DOM, if I access it again to check it's value, I will only get the original value in the document. To do the dynamic buttons, I need to maintain some kind of state between function calls, so that I know what the current size is. Can I even do this with Javascript or am I barking up the wrong tree?

Adjusting Function For Multiple Calls?

Oct 17, 2010

I have a search function which works when I only want to have only one search per page, but as it involves a string call I'm not sure how to modify it to multiple search requests on a page.

The below works fine for one call:

<script type="text/javascript">
function showHint(str){
if (str.length==0){

[code]...

The above doesn't work and I am not sure what do about the showHint(str) as clearly I am not representing it properly in my attempt to modify the script.

Javascript Object Function Calls

Mar 7, 2006

I am creating a JavaScript object which I want to use to respond to user input on a web page. The object will basically be made up of a constructor and then a selection of functions which will use the DOM to alter the appearance of the page according to the user's input. I am getting stuck because I want a form element that is being created by the object to have an 'onkeyup' event attached to it which will call another function from the same object.

Now, I understand how to attach the 'onkeyup' event to the input element I have created using the DOM. If I tell the event to call a normal function (alert() etc) then it does exactly that. What I am having trouble with is getting the event to call another function from the object that created the input box in the first place. (I don't even know if this is possible / a wise thing to do!). Code:

Two Calls For The Same Window Function, But One Fails?

Aug 16, 2011

Two calls, one from a form and one from the html body reach the same 'window.open' function but only the former works.

The idea behind the simplified script of my post is to select to open one of two windows (files) by pressing one of two buttons. Each button passes a different parameter to the 'open/focus' window function. This function has an argument(arg) place holder to determine which window(file) to open(or focus) when a button is pushed and a corresponding string(argument) is passed. The window function is simply a double function,repeating the same if-else statements. That is, with the function(arg): "if(if-else) else(if-else)", the argument passed to 'arg' will determine if[to] {open else focus file1(button1)} else[to] {open else focus file2(button2)} in a new window.

Using a PC with either Explorer or Firefox, both the form button and the button coded in the html body opened a new window, but only the form button could bring the window forward(via 'object.focus') if it was already open. Using a Mac with Firefox, the form button worked well either to open or to bring forward an existing window, but the the button coded in the html body did nothing. Two 'alert' are place in the window function to show that the html button's call is reaching the window function. My question is that if this call from the html button passes through the same statements as that of the form button, why does it fail? (The script is in Perl, but it can be viewed as html in the source page.)

PHP Code:

#!/usr/bin/perl  -w
use CGI qw(:standard);use CGI::Carp qw(fatalsToBrowser);use strict;
my $query = new CGI;
my $JSCRIPT=<<EOF;

Multiple Function Calls From A Single Js File

Dec 11, 2007

i have 4 images that expand onMouseOver and shrink onMouseOut

<script src = 'js/size.js'>

<div id = 'img1' onMouseOver = "expand(this.id)" onMouseOut = "shrink(this.id)">
<img src = ...>
</div>
<div id = 'img2' onMouseOver = "expand(this.id)" onMouseOut = "shrink(this.id)">
<img src = ...>
</div>

etc...

question: when i quickly move the mouse from one image to the other shouldn't i see one expand and one shrink simultaneously? i am currently seeing one shrink, then the other expand after. on occasion the shrink is skipped and the next image is expanded right away.

JQuery :: Changing The Id Of A Form That Calls A Function?

Nov 21, 2011

There is a line in a jquery plugin that I am using that calls a function to run on the inputs of form "autoSubmit."

Code:
$(function(){
$('#autoSubmit INPUT').autoSubmit();
});

My problem lies in that I have multiple of these forms on a single page, each one named autoSubmit. I easily rename each with PHP to autoSubmitXXX or YYY depending on their record id numbers, but then the .autoSubmit(); function doesn't know which form to work with.

Code:
'#autoSubmit INPUT'

I can grab the individual form ID (XXX or YYY) with:

Code:
var where_val = form.find('#where').val();

JQuery :: Using .ajaxError And Passing Error Function In Ajax Calls?

Jun 25, 2010

I'm currently rewriting all my ajax calls to use the jquery method (much cleaner code! ) and have declared a default ajaxError function, shown below:

$(document).ajaxError(function(event, request, settings){
alert("There was an error while communicating with the server. URL: " + settings.url);
});

However, now I have a few ajax calls where I want to declare an error function in the ajax call. I was hoping that by declaring an error function in the ajax call, it would replace the default error call I have defined. But that does not appear to be the case, as I continue to first get my ajax function error call, then I also see the above code execute.

I tried calling event.stopImmediatePropagation() from within my ajax error function hoping that it would stop further events firing (ie: the default error event) but that didn't do anything except tell me in firefox that "event" was undefined.

I was hoping I wouldn't have to go through and define an error function to EVERY ajax call.

AJAX :: Auto-complete - What Code To Be Use On Both The Div (mouseup, Mousedown...) And Then The Function That Calls?

Dec 23, 2009

Im currently creating a textbox with an AJAX auto-complete feature but have reached a wall. I can create a div below it with a list of results but now need to allow the user to select. I can setup it up with an onClick, easy. But I need help with the arrow buttons as that is how I would like it to function. The script only allows 5 results at a time with each having an id of 0 to 4. Each result is a div, below is this code (created by PHP):

PHP Code:
echo "<div id='".$i."' class='userSelect'>".$i.$row["friendName"]."<div>";

There is a JS file attached to the page this is echoed onto, so what would the code need to be on both the div (mouseup, mousedown...) and then the function that calls.

Each Thumbnail Would Need Their Own Bit Of Code That Calls On A Function Related To The Full Size Image Url?

Mar 12, 2009

I am trying to make a site for a photgrapher where the user see's thumbnails of his pictures, then when the pictures are clicked on I want them to open up in a dynamic content box.I can only assume that this is JS/AJAX coding that does this.I have found the following bit of code that does almost this. Except it performs the function on page load and not on mouse click and it opens one of two pages randomly.

var interstitialBox={
//1) list of files on server to randomly pick from and display
displayfiles: ['samplecontent.htm', 'samplecontent2.htm'],[code]...

from what I can tell, each thumbnail would need their own bit of code that calls on a function related to the full size image url.
