I know something about unobtrusive javascript but I don't know how to do it. Thank you very much Similar TutorialsHi, Does anyone know how to make the cycle function in jquery unobtrusive? I've got the following code and when I disable javascript, I get a nasty long list of images Jquery code: $(document).ready(function() { $('.homepage-slideshow').cycle({ fx: 'fade', befo onAfter, pause: 1, timeout: 0, pager: '#nav' }); }); function onAfter() { var cycle_href = this.href; var brokenstring = this.title.split(" :: "); var cycle_title = brokenstring[0]; var cycle_descr = brokenstring[1]; $('#output').html('<a href="'+cycle_href+'">'+cycle_title+'</a>'); $('#output-descr').html(cycle_descr); } Html code: <div class="homepage-slideshow"> <a href="http://url.com/" title="Info goes here."><img src="<?=SITE_URL?>/images/image1.jpg" alt="Click here for more on ..." ></a> <a href="http://url2.com/" title="Info goes here."><img src="<?=SITE_URL?>/images/image2.jpg" alt="Click here for more on ..." ></a> </div> <div class="homepage-pagination" id="nav" >Click the links to start the Google Tour: </div> <div class="homepage-metadata"> <p id="output-descr"></p> <h3 id="output"></h3> </div> First off by let me stating that I am not a great web devloper nor am I a good with css / javascript. I am creating this website for a friend of mines company and I have one problem. The problem is that the navigation menu on the right side will not remain fixed how i want it to be. I spoke with many people and they all said that this cannot be done with css considering your layout and because it needs to dodge the headers and the footer. I basically want this div (sidenav on the right) to scroll along the page as users scroll up or down but it can not interfere with the header or footer. Could someone please post an example or if anyone has the time please tell me exactly what code I need to add to get this to work? keep in mind that i do not want the right side navigation to go over the content or out of the wrapper. I want it to stay in the same position in all aspects - left / right / top / bottom. Here is a link to the site http://www.collisionbodyworks.com/Pl...tic/index.html Any help would be greatly appreciated. Thank you in advance So i've written abit of code myself in order to do this: I will have multiple video tags on my website, each of the video tag's will have to be able to play/pause seperatly, so technically speaking only 1 video should be playing at a time, when the user 'onmouseout' it should pause and when the user's gos to another video that other video should start playing. If he move's the cursor out of the video it should stop... The problem is now, i have video A & B. When i go 'onmouseover' video B, video A starts playing. This is how i started coding: 1 . 2 functions for playing/pausing a video tag 2 . Check how many <video> tags are on the page (after load) 3 . Add Event "mouseout" + function to each <video> tag And the actual code: Javascript: Code: /*** FUNCTIONS OM DE MOUSEOVER & OUT TE DOEN WERKEN ***/
function speelFilmpje(){
document.getElementById("filmpke").play();
}
function stopFilmpje(){
document.getElementById("filmpke").pause();
}
window.onload = function(){
/*** FUNCTION DIE ONMOUSEOVER & OUT FUNCTIE AAN 'VIDEO' TAGS TOEVOEGT ***/
var video = document.getElementsByTagName('video');
var videotags = video.length;
//console.log(videotags);
for(i=0; i<videotags;i++){
video[i].addEventListener("mouseover", speelFilmpje,false);
video[i].addEventListener("mouseout", stopFilmpje,false);
}//einde van de functie
}
HTML: Code: <div id="right_column">

Any thoughts or information is welcome. I've stumbled upon my own wall of "Lack of knowledge" -_- I am trying to remove all Javascript code from my HTML doc and put into external .js file(s). I have event triggers that I would like to move to an external file, but I am not sure how. Below is an example. [CODE] <a href="residential.html" class="textdeco" > <img class="img-menu" id="res" src="images/buttons/btn_res_mouse_out.jpg" alt="Residential" onmouseover="FP_swapImg(1,0,/*id*/'res',/*url*/'images/buttons/btn_res_mouse_over.jpg')" onmouseout="FP_swapImg(0,0,/*id*/'res',/*url*/'images/buttons/btn_res_mouse_out.jpg')" onmousedown="FP_swapImg(1,0,/*id*/'res',/*url*/'images/buttons/btn_res_mouse_down.jpg')" onmouseup="FP_swapImg(0,0,/*id*/'res',/*url*/'images/buttons/btn_res_mouse_up.jpg')" /> [CODE] The reason I want to do this is that this code is repeated in all pages and I want to reduce potential maintenance issues. Any help will be appreciated. without outside extensions, how does one debug javascript events on a webpage that primarily relies on unobtrusive JS events? for instance, i have a website i log into that has a "submit" button. the button itself only has this code: Code: <input type="image" class="png" tabindex="5" value="Go" src="login.png"> obviously, the only way that it can submit the form is to use javascript. and it's obviously unobtrusive in this case. consider the fact that it isn't my webpage, and i don't want to try to put random breakpoints everywhere blindly. any help!? i am trying to make an online graphing calculator with javascript. dont ask how because i dont know. but there is an annoying error in a do...while loop. although it should break out of the loop when the |'s (absolute value signs) are replaced with Math.abs( and ). here is the code. Code: var initec = function(){
var rg = {
}
;
rg.matc = false;
rg.i = 0;
rg.change = function(equ){
if (typeof(equ) != "string"){
alert('Equation must be a string');
return;
}
alert("starting equation: "+ equ);
rg.i = 0;
do{
rg.matc = equ.match(/\|/);
if(rg.i === 0){
equ.replace(/\|/, " Math.abs(");
rg.i = 1;
alert("1 "+equ);
}
else {
equ.replace(/\|/, " ) ");
rg.i = 0;
alert("0 "+equ);
}
}while(rg.matc)
alert("finished equation: " + equ);
}
return rg;
}
rg=initec();
rg.change("|8/x+7|-2");
the last 2 lines and the alerts are for debugging. as you can see, it is not finished. but still, it should work. Hi I'm looking for a very simple script to replace one div with another. I've found a few but they seem overly complicated with features I don't need. I simply want to be able to click on a div and for it to be replaced with another div previously hidden. If someone could suggest a solution or point me in the right direction I'd really appreciate it. Thanks I found a regular expression that will strip my string of every html tag... var stripped = htmlStr.replace(/(<([^>]+)>)/ig,""); Well, I also want it to strip every thing between parentheses, square brackets, and replace " &# 160;" with a space. It would be really cool if you could explain how to do this as well, because the stuff in the above code after "replace" confuses me. I have no idea how that's working. First of all, I don't want to replace text in a form, or on click. I'm writing up a design document in HTML, and I need an area to display code. The < and > tags won't show up, obviously, but to make it easier on the programmer, I don't want him to have to manually put in < and > for each time it shows up. I am aware that JavaScript has a replace function, but I am not familiar with JavaScript quite yet. Is there a way to have JavaScript find the < and > in a certain div, and replace it with < and > on load? I would appreciate your help so much, Its been frustrating me. in the div class "done" it reads 13/34 i want to compare these to numbers like this if (13 < 34){do something()} else {return false;} so i am trying to get each number by it self to compare with. var did=m[1].getElementsByClassName("done")[1].innerText.replace(/\/.*/,"").value; this line returns 13 correctly. var need=m[1].getElementsByClassName("done")[1].innerText.replace(? ,"").value; this ? the info that i need to get for the other number. i know how to do it if it were a letter but can find the correct way being that it is a / instead. Thx Building a shopping cart, at the moment I have 1 variable array. My JS gets values from hidden inputs when add to shopping cart is clicked. The JS then pushes them all into the array in order. I've managed to get the js code to replace innerHTML and add the array to the HTML to show the products, quantity and totals in a table. However its only showing the last product, price, and total in the array in the table. I need to get it to do this: Product: Quantity: Total: Product1 1 1 Product2 2 2 Product3 3 3 So basically I think I need to have my 3 for statements then plus 2 to each i instead of i++ to print out the products but that still doesn't solve my problem with printing every product in a vertical list, same with quantity and same with total. Heres the code Code: var cart= new Array();
function readInput(){
var prd=document.test.prd.value;
var prc=document.test.prc.value;
var qty=document.test.amount.value;
var total= prc * qty;
cart.push( prd )
cart.push( qty )
cart.push( total );
var lenp=cart.length;
for(var i = 0; i<lenp-2; i++ ) {
document.getElementById("product").innerHTML = cart[i];
}
for(var i = 0; i<lenp-1; i++ ) {
document.getElementById("qty").innerHTML = cart[i];
}
for(var i = 0; i<lenp; i++ ) {
document.getElementById("total").innerHTML = cart[i];
}
}

id_tezaver = arr1[0];
term = arr1[1]
// if arr1[1] contains ', then ewerything after that disapears inside term,
// like "bird's eyes" becomes "bird"
// how to handle that ?
// bad example how I get to verify that the stuff is complete inside array
// term = arr1[1].replace(/'/i, /oo/);

Building a javascript shopping cart for an assignment. First time using Javascript so ignore the ****ness of it please Anyway basically I need to replace the qty of an item in an array if the item has already been added to the array. if it hasn't then it adds the normal values to the array. So I assume atm that I have to run an if statement when the function Code: function readInput(prd, qty, prc){
is called that checks in the array before pushing the new values into the array if array contains product name then var id = productarrayID+1 then replace that with the new quantity read in by the form. Quantity in my array is after the product name so I assume productarrayID+1 would give me the qty id variable. So heres the steps, be they correct: 1) get product name from HTML. 2) check if array contains product name. 3) continue with adding to array if product name doesn't exist in array. 4) if array contains product name retrieve id of product name within array. 5) + 1 to the ID to the product name thus giving me the ID for the quantity. 6) run some array.replace with the new id and replace with the quantity. Just wondering if thats a year or no to how that would run. Il post my HTML code but please dont post solutions I would prefer to write the code myself but just checking if the step-by-step process would work thankyou. HTML: Code: <!DOCTYPE HTML>

I have a javascript that takes information from a form and recompiles that information into a readable shift report. The problem I am having is with returns in the textareas. I tried: Code: theReport = theReport.replace("
","<br>"
but that space puts the rest of the var on a different line and screws with the results. How can I replace a return with <br>? How would you do a .replace for a Javascript if statment.
I know how the replace method works, but I can't for the life of me figure out exactly what this replace function is doing... Can someone shed somelight for me? the g I *think* is a flag for global replacement... Code: replace(/\s/g, " "); I know that *something* is being replaced by a non-blank space, but what? Does anyone know if it it possible to automatically replace any instance of & with 'and' using javascript when someone types into a text input?
Hi, I need function for replacing one string with some html tag (for example <div>something</div>) in web page. Tricky is that in this replacing I must ignore all text between <a> and </a>. It's look easy but I am not good in javascript.
if it fails (does not find the string)? I thought it gave out the value 'null' or some such, but apparently not. Basically I want a function to execute, but only if replace will work. I need to do this as concisely as possible... Is there a simple way to do this? Otherwise is there an 'include' function or something I could use to check for a string in a value and make it's existence the premise on which an if statement works? Thanks in advance, sorry if this was incoherent... late nights and all. |
