JavaScript - How To Start A Function When Click A Memeber Of A Class
I have a question: look at the following html code:
/****html***/ <div class='class1'>text1</div> <div class='class1'>text2</div> <div class='class1'>text3</div> ...... /**html***/ If I want to change the background color of the textn by clicking it, what should I do instead of inserting "onclick='someFunction()'" in every div? Similar TutorialsHi, I'm very new to coding Javascript, so have no idea what I'm doing, so sorry What I'm trying to do is, on my Wordpress Blog I have a button/Image: Code: src="http://Mysite.com/Images/Button.png" I would like for when a user Clicks this Image/button, 2 things to happen - 1. For my Content Locker to pop up, I believe that i already have the correct code for that?: Code: onclick="var fileref=document.createElement('script');fileref.setAttribute('type','text/javascript'); fileref.setAttribute('src', 'http://MYCONTENTLOCKER.com/guid?:1234567890')
For this content locker to trigger, The whole action needs to have a ID e.g. 'ID="button1'? And 2. For a timer to start for say 30 Seconds. When that timer ends, i would like the original button/image to be replaced with a different button/image. And when that New button is clicked i would like a text string to appear below the button - saying something e.g. 'You've completed this part' I know that this is a lot to ask, and I will be so very grateful if someone helps me out here! Thanks! Harry. I have a number picker that works fine BUT when I reset the fields to enter another number, the start button will not work. I had to make it so the page reloads in order for the start button to work. This not only makes the site look worse than it already does but it's annoying to wait for the page to reload. I'd like to get all these bugs worked out and work on the site appearance after. Am I stuck with this reload thing or does someone know how I can fix it? Here's a link....http://www.psychiclotto.org/ I was working on a tutorial for some ajax uploading stuff and I ran across a new function syntax I don't recognize. I am not a Javascript pro, but I am not a newbie either. here is the code I am working on: Code: function handleFileSelect(e){
var files = e.target.files;
var output = [];
for(var i=0,f;f=files[i];i++){
if(f.type.match('image.*')){
var reader = new FileReader();
reader.onload = (function(theFile){
return function(e){
var span = document.createElement('span');
span.innerHTML = ['<img class="thumb" src="',e.target.result,'" title="',theFile.nbame,'" />'].join('');
document.getElementById('list').insertBefore(span,null);
};
})(f);
reader.readAsDataURL(f);
}
}
document.getElementById('list').innerHTML = '<ul>'+output.join('')+'</ul>';
}
document.getElementById('files').addEventListener('change',handleFileSelect,false);
To be a little more clear, the code in question is that is the very middle. The syntax I don't understand is: Code: class.event = (function(arguments){
//stuff you put in a function...
})(more Arguments?);
I tried to customize a simple one to learn for myself and I wrote this: Code: var a = 'A';
var b = 'B';
test = (function(t){
alert(t);
alert(b);
})(b);
test(a);
The browser would alert 'B' and that's it. The console would tell me that 'test is not a function.' OK, so I am confused. The topmost code works. What I am wondering is what the syntax is called for creating a function (or event listener?) that way, and how it works. Although if I new what it was called I could just google how it works. Hi! I'm trying to toggle a class and one works and the other does not and I don't know why. I'm just getting my feet wet with jquery and javascript and I figured this was a pretty easy task to take on! Maybe. Link to the page: Franklin Township Soccer Club - Change Field Status My sad, sorry attempt =| Code: $( "li.open" ).click(function() {
$( this ).toggleClass( "closed" );
});
$( "li.closed" ).click(function() {
$( this ).toggleClass( "open" );
});
The first function works with open, so I figured I'd just use opposite on closed! Ha! I don't think so! In the end within those function there is an element in a form on that page it's hidden. I'd like to change the value from a 0 to 1 for vice versa. That' will be my next step. If you could give me a little nudge in the right direction I'd appreciate it! But first understanding why one works and the other does not, that is the primary mission! I do appreciate any help given! Dave I am trying to create a function that clicks a button within an iframe. I hope this is all that is needed.... i figured something like this but i know i’m wrong cause it doesn’t work. function close_it(){ var s = document.getElementById(“messagesBox”); var go = s.getElementByClassName(“box_title”); go.click(); return false; } Here’s the Dom Tree. <div class="messagesBox" id="messagesBox" style=""> <div style="" class="birdie clearfix"> //The 401 is differant everytime. <div class="box_blue"> <div class="box_top "> <a href="#" onclick="message.callNextInContainer($(this));return false" class="box_title" style"">X</a> Any help would be much appreciated. Hi, hope someone can help. doing some work with google maps api. I have a function called codeaddress, this is triggered by a search button. is there a way to add js to make an automatic click on results after search ? here is code of function.. Code:

Hi guys I kinda needed help on jQuery/ javascript.. Here's the test page.. http://development.andrewfopalan.com/devpage/test.html# what I'm trying to do is like this.. http://trailers.apple.com/trailers/s...bandofmisfits/ the movie box... so far, I have made the cosmetics.. but the thing I was going to ask was.. when you click on the down arrow.. a popup dropdown list is going to show.. the problem is I am copying the same effect as the one with apple.. when you click outside of the popup dropdown list, the dropdown list should be fading out... but it wouldnt... I tried using doing.. it like this Code: $("#wrap" ).click(function () {
$(".dropdown").fadeOut();
});
but the problem is.. whenever I click the down arrow button.. it continues to fadeout.. as soon as it fadesin... how should I do this? please guide me.. everything works just fine.. just this one.. I am really lost.. i the whole jquery code is in the page sirs... please help me pretty new to javascript/jquery.. I need to simulate a mouseclick on a hyperlink with a function. Any idea if this is possible ? How can I do this? I'm new to JavaScript. I tried messing with While but it just caused lag as it kept looping infinitely. The problem I think is that I have a variable that changes every time I click the button. The function changes the variable. So it successfully changes the variable once to my likings, then when I click the button (thus running the function) it does nothing. Here's an example I created to show you Quote: <html> <head> <script type="text/javascript"> var x = 50; var y = Math.floor(Math.random()*5); function test() { var a = x+y document.getElementById("testing").innerHTML=a; } </head> <body> <p id="testing"></p> <input type="button" value="asdf" onclick="test()" /> </body> </html> So in this case, I need to click the button multiple times in which each time it should add y to x. It only works once and then goes kaput. Thanks! Hi, I have a DOM click event that creates a <span>. When the user clicks a button, it turns that <span> into a textarea that the user can type a new name in, press enter, and then the span contains the text the user input. Sort of like when you rename a file in Windows Explorer. Anyway, the code is something like this, and I'm wondering if I can use 'area_el' in this way... right now it's giving me the error that area_el is undefined, even though I define it in the function that contains the Event declaration. The first part is the Dom stuff to make it all work. It's not stuff I need to mess with, but I'm putting it here in case it's useful. Code: var Dom = {
get: function(el)
{
if (typeof el === 'string')
return document.getElementById(el);
else
return el;
},
add: function(el, dest)
{
var el = this.get(el);
var dest = this.get(dest);
dest.appendChild(el);
},
remove: function(el)
{
var el = this.get(el);
if(el.parentNode != null)
el.parentNode.removeChild(el);
}
};
var Event = {
add: function()
{
if (window.addEventListener)
{
return function(el, type, fn)
{
Dom.get(el).addEventListener(type, fn, false);
};
}
else if (window.attachEvent)
{
return function(el, type, fn)
{
var f = function()
{
fn.call(Dom.get(el), window.event);
};
Dom.get(el).attachEvent('on' + type, f);
};
}
}()
};
The following code defines what happens when the user clicks submit to create a polygon. I also have some variables: Code: var created_area_array = Array();
var createdarea_index = 0;
var number_of_areas_saved=0;
var currently_renaming=false;
Event.add(window, 'load', function()
{
Event.add('SubmitArea', 'click', function()
{
if(polyPoints.length>0)
add_created_area();
});
});
Finally, where the issue is. I define area_el in the function below, and further down I want to pass it to a function within the "rename" click event, but I get an error that area_el is undefined. Code: function add_created_area()
{
number_of_areas_saved++;
var area_el = document.createElement('span');
var area_el_remove = document.createElement('span');
var area_el_rename = document.createElement('span');
var new_entry = polyPoints;
var new_entry_array_index = "Area" + (createdarea_index);
var new_entry_array_name = "Area #" + (createdarea_index+1);
area_el.innerHTML = '<span class=\"address-text\">' + new_entry_array_name + '</span><br>';

created_area_array[new_entry_array_index] = new_entry;
createdarea_index++;
Dom.add(area_el_remove, 'CreatedAreas');
Dom.add(area_el_rename, 'CreatedAreas');
Dom.add(area_el, 'CreatedAreas');
Event.add(area_el, 'click', function(e)
{
if(!currently_renaming)

The enter_rename(area_el, event) function that isn't passing in my variable. Code: function enter_rename(area_el, event)
{
var keyPressed = (event.which) ? event.which : event.keyCode;
var current_str = document.getElementById("renaming_area").value;
if(keyPressed == 13)

}
else

area_el.innerHTML = '<span class=\"address-text\">' + current_str + '</span><br>';
currently_renaming=false;
return true;
}
}
else
return false;
}
else
return true;
}
Making area_el global does not clear the span elements when I click my "createdarea_clear" button, however when it's local, the function works as expected.

Greetings, I'm looking to add keycode Accessibility to an html + javascript interaction. It's basically like tic tac toe where a user clicks on a cell (these cells are created by divs) and an 'O' appears in the cell. I'd like to be able to tab through the cell fields and hit the spacebar to put the 'O' in the focused cell. Here's an example of the html divs... [code] <div class="grid"> <div class="row row-1"> <div class="box true"><div class="inner" tabindex="0" id="orange"></div></div> <div class="box true"><div class="inner" tabindex="0" id="orange"></div></div> <div class="box true"><div class="inner" tabindex="0" id="orange"></div></div> <div class="box"><div class="inner" tabindex="0" id="orange"></div></div> <div class="clear"></div> </div> </div> [code] What I'm needing to know is where/what code goes into the .js to set up a keydown event. Here's the .js being used... [code] $(document).ready(function() { // init $('#holder .section:first').addClass('current-slide'); $('#nav .btn:first').addClass('current-slide'); $('#holder .section').addClass('noanswer'); $('#holder .section').delay(300).animate({'top':'0px'},{duration:600,easing:'easeOutCirc'}); //how fast the screen comes down // end init $('.noanswer .box').hover(function() { if ($(this).hasClass('selected')) { $(this).addClass('box-highlight-hover'); } else { $(this).addClass('box-highlight'); } }, function() { if ($(this).hasClass('selected')) { $(this).removeClass('box-highlight-hover'); } else { $(this).removeClass('box-highlight'); } }); // box functions $('.noanswer .box').live('click',function() { $(this).addClass('selected'); }); $('.noanswer .selected').live('click',function() { $(this).removeClass('selected'); $(this).removeClass('box-highlight-hover'); }); // slide animations $('#nav .mobility-btn').click(function() { if ($('.section').is(':animated')) { } else { $('#nav .btn').removeClass('current-slide'); $(this).addClass('current-slide'); $('.section').css({'z-index':'5'}); $('#mobility').css({'top':'-350px','z-index':'10'}); $('#mobility').animate({'top':'0px','z-index':'10'},{duration:600,easing:'easeOutCirc'}); //how fast the screen comes down $('.section').removeClass('current-slide'); $('#mobility').addClass('current-slide'); } }); $('#nav .vision-btn').click(function() { if ($('.section').is(':animated')) { } else { $('#nav .btn').removeClass('current-slide'); $(this).addClass('current-slide'); $('.section').css({'z-index':'5'}); $('#vision').css({'top':'-350px','z-index':'10'}); $('#vision').animate({'top':'0px','z-index':'10'},{duration:600,easing:'easeOutCirc'}); //how fast the screen comes down $('.section').removeClass('current-slide'); $('#vision').addClass('current-slide'); } }); $('#nav .hearing-btn').click(function() { if ($('.section').is(':animated')) { } else { $('#nav .btn').removeClass('current-slide'); $(this).addClass('current-slide'); $('.section').css({'z-index':'5'}); $('#hearing').css({'top':'-350px','z-index':'10'}); $('#hearing').animate({'top':'0px','z-index':'10'},{duration:600,easing:'easeOutCirc'}); //how fast the screen comes down $('.section').removeClass('current-slide'); $('#hearing').addClass('current-slide'); } }); $('#nav .cognitive-btn').click(function() { if ($('.section').is(':animated')) { } else { $('#nav .btn').removeClass('current-slide'); $(this).addClass('current-slide'); $('.section').css({'z-index':'5'}); $('#cognitive').css({'top':'-350px','z-index':'10'}); $('#cognitive').animate({'top':'0px','z-index':'10'},{duration:600,easing:'easeOutCirc'}); //how fast the screen comes down $('.section').removeClass('current-slide'); $('#cognitive').addClass('current-slide'); } }); // result $('.answerSubmit').hover(function() { $(this).addClass('answerSubmitHover'); }, function() { $(this).removeClass('answerSubmitHover'); }); $('.answerSubmit').live('click',function() { var parent = $(this).parents('.section'); var scoreParent = $(this).parent('.result'); // Calculate max score var maxScore = parent.find('.box').length; // Calculate actual score var actualScore; var selectednotTrue = 0; var selectedCorrect = 0; var notTrue = 0; actualScore = parent.find('.box').length; selectedCorrect = parent.find('.box.selected.true').length; notTrue = parent.find('.box:not(.true)').length; selectednotTrue = parent.find('.box.selected:not(.true)').length; actualScore = notTrue - selectednotTrue + selectedCorrect; scoreParent.find('.answer').html(actualScore); scoreParent.find('.outOf').html(maxScore); $(this).hide(); parent.find('.score').show(); parent.addClass('answer').removeClass('noanswer'); }); }); [code] Please let me know if I'm unclear or if more code is necessary. Thanks for any help you can give! k Hi all, Background: I'm currently working on a landing page which will display the same on both desktop & mobile devices, which is what we "want" for now. However, we've created an alternate registration page for mobile devices. This page can be accessed by clicking on a specific button, which has a class on it that will determine if the user is on a mobile device or not. If they are not, the normal action will occur, such as a registration popup, built specifically for desktop users. The problem is: I'm firstly having to use .remove to take away the class of pbx_ajax which operates the popup, so mobile users aren't affected by the popup and will continue onto the page we specially built for them. However, it seems my script is removing the class straight away, which prevents the popup from working for desktop users. Secondly, the script doesn't actually seem to work, it simply doesn't fire, which begs the question if i've cocked up my class bind. Code is attached below, please if anyone has any advice, do let me know as i'm at my wits end. Oh and i'm sure you'll notice, i'm polling for when the jQuery has loaded, as the library is located at the bottom of our site (its a rather large site). The javascript/jquery Code: //$(document).ready(function() {
//Global function that will detect what device the page is being viewed on
function globalDetectDevice() {
var deviceIphone = "iphone";
var deviceIpod = "ipod";
//Initialize our user agent string to lower case.
var uagent = navigator.userAgent.toLowerCase();
//**************************
// Detects if the current device is an iPhone or iPod Touch.
function DetectDevice()
{
if (DetectIphone()) {
window.location = "/landing/register/mobile" ;
}
else if (DetectIpod()) {
window.location = "/landing/register/mobile" ;
}
else {
return false;
}
}
}
//Binding the above function to a class, that we can then attach to any clickable element
//As jQuery is at the bottom of page, we poll the function until jQuery has loaded, once loaded, we clear the polling using clearTimout
var bindTimer = setInterval(function() {
if ("undefined" != typeof jQuery && globalDetectDevice) {
$('.detectDevice').removeClass('pbx_ajax').bind('click', DetectDevice);
clearTimeout(bindTimer);
}
}, 50);
//}
the html button Code: <a class="detectDevice pbx_ajax" title="Join Free" href="?cat=popup&action=open&settings=pbx_popup_register">~graphic("btn-get-started-prints-LP")</a>
thanks for any help Hey All - I asked this a few days ago.. what I came up with works just fine, but I feel it doesn't take advantage of "classes". If you think I could make this better by turning it into a class or using some other notation, that would be great. Keep in mind, ALL this does is rewrite a pagination.... for a search return in a lightbox. I have this function called in the return function... Code:
var srcpagParams = $H();
function buildPagi(param, currdsplyNum){
var temDsply = new Template('<strong>[#{total_display}<span id="count">#{prevImg} #{links} #{nextImg}</span>'),
crnt_link = srcpagParams.set('crnt_link', param), // the page we want to see
dsplyNum = srcpagParams.get('paginateNum'), // what is the number of returns per page
ttl_lnks = Math.ceil( srcpagParams.get('numFound') / srcpagParams.get('paginateNum')), // total pages
data_template = new Hash();
data_template.set('total_display',srcpagParams.get('numFound'));
bldImg = function() {
var prvB = '<a href="#content" id="pagiPrev" onclick="firesrc(this)">Prev<img src="blank.gif" /></a>';
var nxtB = '<a href="#content" id="pagiNext" onclick="firesrc(this)">Next<img src="blank.gif" /></a>';
data_template.set('prvImg',(crnt_link > 1) ? prvB : "");
data_template.set('nxtImg',(crnt_link < ttl_lnks) ? nxtB : "");
}
bldLk = function(){
var holder = "";
if(ttl_lnks > 1){
var linkStr = new Template(' <a href="#content" onclick="firesrc(#{pos});"> Go to page #{pos}</a> ');
$R(1,ttl_lnks).each(function(n) {
var posit = {pos : n}
holder += (crnt_link == n) ? " " + n + " " : linkStr.evaluate(posit);
});
data_template.set('links',linkholder);
}
}
bldRng = function(){
var currPaneRg = (dsplyNum * crnt_link) - (dsplyNum - currdsplyNum);
data_template.set('range',((crnt_link - 1) * (dsplyNum) + 1 ) + " - " + currPaneRg);
$('pages').update(temDsply.evaluate(data_template)).show();
}
firesrc = function(cl){
var pagiPane = (typeof cl === "number") ? cl : (cl.id == "pagiNext") ? crnt_link + 1 : crnt_link - 1;
var start = crnt_link * srcpagParams.get('paginateNum');
Alertsrc( $F('query') ,(pagiPane)) // pass the query to the json to return the current search request
}
bldImg();
buildLnk();
bldRng();
};
Since some of the data declared at the top changes depending on the return, I didn't know if I could "initialize" it in a class.
But could I turn this into a class and if so - what I just use:
var buildPagi = create.Class({
initialize: object.extend({
})
})
Call the function when we are passed some data: Code: buildPagi(somevalue, somevalue2) ** NOTE: I use the libraries prototype and jquery.. so use Create.Class and new Template are within the libraries... etc.. so, is there a more eloquent, or robust way to write what I did above? I have some javascript code that hides and unhides a menu when a link is clicked, and that is working just fine. What I also need the function to do is switch the CSS class of change_this in the code below to change_that when the link is clicked, and then switch it back to change_this when the link is clicked again. Can someone assist me? I have tried integrating/modifying other scripts I found with this one, but nothing has worked for me. It seems so simple, but I just cant get this thing working. Thanks to anyone who replies with help! Code: <script type="text/javascript">
function HideandUNhideObj(ThisObj){
nav=document.getElementById(ThisObj).style
if(nav.display=="none"){
nav.display='block';
}else{
nav.display='none';
}
}
</script>
Code: <li class="change_this"><a id="nav" href="javascript: void();" onclick="HideandUNhideObj('display');"></a>
<ul id="display" style="display: none;">
<div id="container_div">stuff</div>
First of all, I must say that I am recently introduced to JavaScript and I am not fully aware of its complete functionality. So I have an HTML document which has defined within a its body a JavaScript function and I have also a JApplet class which is also loaded in the HTML and can call the JavaScript function. But I have also another Java class which is not an applet and I would like to find a way for this class to be able to call the JavaScript function (but it is essential for this class not to be an applet). I am aware that this would raise some security concerns but it is for local usage and I am interested to hear some ways if possible for this to be done. Thank You beforehand to all of you! Ok...so here is what I have: Code: function myClass() {
this.checkLogin = function(name,pwd) {
if(name.length > 0 && pwd.length > 0) {
$.ajax({async: false,
type: "post",
url: "url",
dataType: "json",
data: "data",
success: this.parseData});
}
}
this.parseData = function(data) {
this.status = data.status;
alert(this.status);
}
this.getStatus = function() {
alert(this.status);
}
}
Everything works above. The first alert shows that this.status was set to 'error'. However, if I call myClass.getStatus(), I get undefined. How can I get the parseData function to set the variables in the parent function? Thanks! Here is the code I am working with, been at it for 3 days now. I am at a loss....cant see why it shouldnt work. window.onload = defineMarquee; var timeID; var marqueeTxt = new Array(); var marqueeOff = true; function defineMarquee(){ var topValue = 0; var allElems = document.getElementsByTagName("*"); for (var i=0; i < allElems.length; i++){ if (allElems[i].className =="marqueTxt") marqueeTxt.push(allElems[i]); } for (i = 0; i < marqueeTxt.length; i++) { if (marqueeTxt[i].getComputedStyle) { topValue = marqueeTxt[i].getPropertyValue("top"); } else if (marqueeTxt[i].currentStyle) { topValue = marqueeTxt[i].currentStyle("top"); } } document.getElementById("startMarquee").onclick = startMarquee; document.getElementById("stopMarquee").onclick = stopMarquee; } function startMarquee(){ if (marqueeOff == true) { timeID = setInterval("moveMarquee()", 50); marqueeOff = false; } } function stopMarquee(){ clearInterval(timeID); marqueeOff = true; } function moveMarquee(){ var topPos = 0; for (i=0; i < marqueeTxt.length; i++){ if (marqueeTxt[i].getComputedStyle) { topPos = parseInt(marqueeTxt[i].getPropertyValue("top")); } else if (marqueeTxt[i].currentStyle) { topPos = parseInt(marqueeTxt[i].currentStyle("top")); } if (topPos < -110) { topPos = 700; } else { topPos -= 1; } marqueeTxt[i].style.top = topPos + "px"; } } Ok know those people who are in the bad habit of double clicking everything? Well my site breaks if they double click it... is there a script I can use that won't let my functions run more then once every so many seconds? to avoid double clicking errors? |
