JavaScript - Width Related Rollover Menu
Hi guys, Im not sure my subject decsription gives an exact description of what i am after but i will try and explain my requirements a bit better.
I have an header menu there are items in this menu but there are a lot of them and if you try view on a normal 1024 x 760 you have to horizontal scroll to view all the items, but on my monitor 1920 x 1080 it is fine. I don't want to do it this way since I hate having to scoll both horizontal and vertical. I would like to be able to change the items on this header to become a rollover dropdown menu when they would normally be hidden becuase of the screen width. I have seen this done before I am just unsure about how to implement this. can anyone point me in the direction of some good resources for this? Thanks EDIT---------------------------------------------------------------------------------------------- I am using jQuery if that make it easier to fine a script that would do this Similar Tutorialsneed help adding a one second delay to a drop down menu. don't want people triggering it by accident: http://www.corneliodesign.com/menu/ i used hoverIntent to delay it: http://cherne.net/brian/resources/jq...verIntent.html i got the script in the http://www.corneliodesign.com/menu/s...hoverIntent.js but it's not actually working for me. please see if could look at code, tell what's wrong or gimme another options, would be extremely appreciative, thanks, julio Hi there I've created a nav bar for this site - http://web11.3essentials.com/~cp27358/ - I'm using javascript to handle the image rollover which is working just fine. However I want to add to this so that the current page will stay with the second or rollover image. How would you suggest I edit or add to my code so it keeps the second image active if it is the active page? In my script file this is what I'm using for an image: menu1buttonup = new Image(); menu1buttonup.src = "http://web11.3essentials.com/~cp27358/wp-content/themes/origin/images/menu1.jpg" ; menu1buttondown = new Image() ; menu1buttondown.src = "http://web11.3essentials.com/~cp27358/wp-content/themes/origin/images/menu1a.jpg" ; followed by.... function buttondown( buttonname ) { if (document.images) { document[ buttonname ].src = eval( buttonname + "down.src" ); } } function buttonup ( buttonname ) { if (document.images) { document[ buttonname ].src = eval( buttonname + "up.src" ); } } and this is what my list items look like: <a href="<?php echo home_url(); ?>/?page_id=7" onmouseover="buttondown('menu1button')" onmouseout="buttonup('menu1button')"><img src="<?php bloginfo('template_url'); ?>/images/menu1.jpg" name="menu1button" /></a> thank you Hey guys, Lookin' for a little help, not sure if it can even be done? hopefully someone has the answer. I'm trying to design myself an online portfolio; here's what I got so far... http://www.gregorymstevens.com/testsite/site.html As you can see my navigation is represented by each bird on the tree (every bird is a link), when you rollver one of the green birds they turn white, however, I am looking to not only have the green bird rollver to white but ALSO have the "choose a" image on the bottom right change to the corresponding page. For instance, when the mouse rolls over a bird-- this image: will turn into this image: while maintaining the original "white bird" rollover. Hopefully I'm explaining this correctly -- Any help greatly appreciated! Hello, let me try to explain better what I'm trying to do. I'm a real newbie I don't know much javascript but I understand more or less the logic behind it... tell me if this solution should work and if you know how to do it please show me. I have this page. http://felixdeportu.com/5/ The images are inside a div#content div#photo. I need to make div#photo's width to match the total width measurement of all the images it contains. If you load the page and you don't touch the size, it will work fine... but that's not realistic. If I resize the page, which will happen often on this kind of page (I'm assuming), the whole thing goes haywire (try it, scroll to the last image and resize the page you'll see what I mean). What can I do? Is my idea the right solution? Am I not explaining this clearly enough? Let me know please, I'm desperate. I've been trying to get CSS to do this for me for 3 hours now. Nothing works... Okay so if you go to this website: http://gameusd.com/ You can pick your game & country -- say its world of warcraft US And then you pick your realm and faction, and then it gives you the prices on those particular realms/factions. What i wanted to know was if it was possible to somehow make a program that fetches the prices of EVERY single realm/faction and lists them all side by side and in order of lowest to highest price or whatever. Would massively appreciate if somehow could tell me if its possible. Because obviously doing it all manually would be a huge pain in the *** and take hours. I already got the following JavaScript code working somewhat (originally taken from a different thread in a different forum and tweaked to give qty ceiling [10] and floor [2] values). However, it seems to work for only one qty variable, and the subtractQty function doesn't seem to subtract properly (at least in Opera 11). Code: <html>
<head>
<title></title>
<style type="text/css">
</style>
<script type="text/javascript">
function subtractQty(){
var x=document.getElementById("qty").value;
var y=document.getElementById("maxqty").value;
if(x - 1 < 2 || y + x <= 40)
return;
else {
document.getElementById("qty").value--;
document.getElementById("maxqty").value=y+x*4;
document.getElementById("textqty").innerHTML = document.getElementById("qty").value;
document.getElementById("textmaxqty").innerHTML = document.getElementById("maxqty").value;
}
}
function additionQty(){
var x=document.getElementById("qty").value;
var y=document.getElementById("maxqty").value;
if(x >= 10 || y - x < 2)
return;
else{
document.getElementById("qty").value++;
document.getElementById("maxqty").value=y-x*4;
document.getElementById("textqty").innerHTML = document.getElementById("qty").value;
document.getElementById("textmaxqty").innerHTML = document.getElementById("maxqty").value;
}
}
</script>
</head>
<body>
<form name="f1">
<input type='hidden' name='qty' id='qty' value=2 />
<input type='hidden' name='maxqty' id='maxqty' value=40 />
<div id="textqty">2</div>
<input type='button' name='subtract' onclick='javascript: subtractQty();' value='-'/>
<input type='button' name='add' onclick='javascript: additionQty();' value='+'/>
<div id='textmaxqty'>40</div>
</form>
</body>
</html>
What I'd want to happen would be the following: if let's say we have 5 pairs of buttons, making it look something like this: A: 2 [+] [-] B: 2 [+] [-] C: 2 [+] [-] D: 2 [+] [-] E: 2 [+] [-] maxqty: 40 Whenever the user clicks on the [+] button for A, it would subtract (current value + 1) * 4 from maxqty and raise A to 3, then when the user clicks on the [+] for C, it would subtract (current value + 1) * 4 from maxqty and raise C to 3, without having to copy paste multiple functions. I'm already thinking of arrays, but being more used to PHP than Javascript -- and I'm thinking I might actually have to use AJAX for this, although I'm really in the dark with AJAX in particular -- I'm rather confused and somewhat stumped on the coding. Suggestions? Hi Friends, i have a smal task i.e i have textbox1 ,botton,textbox2 when i enter 21 value then i click button its get in sama row values in textbox2. i have xml file like this <DATAPACKET > <ROWDATA> <R_ID>101</R_ID> <R_NAME>R-12</R_NAME> <R_TEMP>4.266</R_TEMP> <R_COLOR>White</R_COLOR> </ROWDATA> <ROWDATA> <R_ID>20</R_ID> <R_NAME>R-22</R_NAME> <R_TEMP>4.266</R_TEMP> <R_COLOR>Green</R_COLOR> </ROWDATA> <ROWDATA> <R_ID>21</R_ID> <R_NAME>R-32</R_NAME> <R_TEMP>4.266</R_TEMP> <R_COLOR>White</R_COLOR> </ROWDATA> <ROWDATA> <R_ID>104</R_ID> <R_NAME>R-134A</R_NAME> <R_TEMP>4.246</R_TEMP> <R_COLOR>Light Blue</R_COLOR> </ROWDATA> <ROWDATA> <R_ID>21</R_ID> <R_NAME>R-290</R_NAME> <R_TEMP>4.246</R_TEMP> <R_COLOR>White</R_COLOR> </ROWDATA> <ROWDATA> <R_ID>31</R_ID> <R_NAME>R-401A</R_NAME> <R_TEMP>4.246</R_TEMP> <R_COLOR>Pink</R_COLOR> </ROWDATA> <ROWDATA> <R_ID>32</R_ID> <R_NAME>R-401B</R_NAME> <R_TEMP>4.264</R_TEMP> <R_COLOR>White</R_COLOR> </ROWDATA> <ROWDATA> <R_ID>108</R_ID> <R_NAME>R-402A</R_NAME> <R_TEMP>4.426</R_TEMP> <R_COLOR>Light Greem</R_COLOR> </ROWDATA> <ROWDATA> <R_ID>129</R_ID> <R_NAME>R-402B</R_NAME> <R_TEMP>4.266</R_TEMP> <R_COLOR>White</R_COLOR> </ROWDATA> <ROWDATA> <R_ID>110</R_ID> <R_NAME>R-404A</R_NAME> <R_TEMP>4.246</R_TEMP> <R_COLOR>Orange</R_COLOR> </ROWDATA> <ROWDATA> <R_ID>121</R_ID> <R_NAME>R-407A</R_NAME> <R_TEMP>4.267</R_TEMP> <R_COLOR>White</R_COLOR> </ROWDATA> <ROWDATA> <R_ID>122</R_ID> <R_NAME>R-408A</R_NAME> <R_TEMP>4.267</R_TEMP> <R_COLOR>White</R_COLOR> </ROWDATA> <ROWDATA> <R_ID>113</R_ID> <R_NAME>R-409A</R_NAME> <R_TEMP>4.267</R_TEMP> <R_COLOR>White</R_COLOR> </ROWDATA> <ROWDATA> <R_ID>134</R_ID> <R_NAME>R-407C</R_NAME> <R_TEMP>4.264</R_TEMP> <R_COLOR>White</R_COLOR> </ROWDATA> <ROWDATA> <R_ID>115</R_ID> <R_NAME>R-410A</R_NAME> <R_TEMP>4.426</R_TEMP> <R_COLOR>White</R_COLOR> </ROWDATA> </DATAPACKET > then i try this hear i get all values function gettxt() { results = new Array; var searchterm = document.getElementById("searchme").value; if (searchterm == null || searchterm == "") { alert("Enter textbox value"); return false; } var istrlen1 = searchterm.length; var tempname1; if (istrlen1 == 1) { tempname1 = searchterm; } if (istrlen1 == 2) { tempname1 = searchterm; } if (istrlen1 == 3) { tempname1 = searchterm; } if (istrlen1 == 4) { tempname1 = searchterm; } for (i = 0; i < x.length; i++) { var name = x[i].getElementsByTagName("R_ID")[0].firstChild.nodeValue; var name1 = x[i].getElementsByTagName("R_NAME")[0].firstChild.nodeValue; var exp = new RegExp(tempname1, "i"); if (name.match(exp) != null) { y = y + 1; results.push(name1); } } textbox2.value = results; } i try the above code hear small problom when i enter 21 and click button its display 21,121,123... related values i dont want like that for example textbox1=21 buttonclick textbox2=R-32,r-407A,r-408A like that i dont want like that i want textbox1=21 buttonclick textbox2=R-32 only in same row value please any one knows well in js please resolve my problom im new to webpage programming,but do hav some basic c/c++ programming skill. in order for me to understand the following codes, what should i read? i had read thru w3schools.com html and javascript tutorials but it is stil difficult for me to understand the codes,can somebody help me?thanks!

I want to set the width of a div to be the same width of the image inside the div. The following code works great. But... The images are different widths, so both wrappers are set to the width of the first image. Without having to add an ID to each wrapper or image, can the wrapper width be set to the image width using the name of the image as the unique identifier? Any help would be great! PHP Code: jQuery: $(document).ready(function(){ var newWidth = $('div.wrapper img').attr('width'); $('div.wrapper').width(newWidth); }); HTML: <div class="wrapper"> <p><img src="image1.jpg" width="200" /><br /> Caption</p> </div> <div class="wrapper"> <p><img src="image2.jpg" width="250" /><br /> Caption</p> </div> Hello: I have a Fire Fox 3.5.2 error console message regarding a DHTML script: Error: uncaught exception: [Exceptions: ... "Not enough arguments" nsresult "0x8057001 (NS_ERROR_XPC_NOT_ENOUGH_ARGS)" Location: "JS frame :: (file path) upHandler :: line 102" no data] The line referenced is: document.removeEventListener('mouseup', upHandler); It is part of a drag function that is applied to a container div. I have successfull used this code block, copied from Orielly's Javascript: The Definitive Guide, 4th Edition in another project. The only real difference is that the code in the working use is div tags hard coded. In the one giving me problems, the div tags are written using document.write() in a function that is called in the body of the document when the page loads. I could supply the code context, but it is several hundred lines. The project is not available at present on the web to surf to but the one project that works is jekillen.com/jekillen/content/web_design/OOP_panel/test_OOP_DEV_ALT.php The code in question is 'beginDrag'. There is a panel called fortune cookie which the user can drag, and a panel called 'Advisory' that the user can also drag around after clicking button labeled 'message'. Any info, suggestions, advice? Thanks in advance. Jeff K I posted this once, but it disappeared, and I have no notifications that I did anything wrong. I read the rules before posting and wasn't breaking any so I am not sure why it disappeared but here goes again. I am trying to learn Javascript (particularly OOP) from a series of screencasts by Douglas Crockford. I have developed a theoretical "game" to build to illustrate it to myself better, and learn by example. I must be misunderstanding how inheritance works, because my code is not producing the results I thought it would. Here is what I have, followed by an explanation of my understanding. Code: $(function() {
function object(o) {
function Funct() {}
Funct.prototype = o;
return new Funct();
}
soldier = {
pointsCost: 0,
movement: "1 Infantry Block",
validTargets: {},
weapons: {
"Main Weapon": {
"Weapon Type": "M4 Carbine",
"Fire Range": 12
},
"Secondary Weapon": {
"Weapon Type": "JCP .45",
"Fire Range": 3
}
}
};
var rifleman = object(soldier);
rifleman.pointsCost += 10;
rifleman.validTargets.target1 = "Infantry"
rifleman.weapons["Secondary Weapon"]["Weapon Type"] = "";
rifleman.weapons["Secondary Weapon"]["Fire Range"] = "";
var heavyGunner = object(soldier);
heavyGunner.pointsCost += 20;
heavyGunner.validTargets.target1 = "Infantry";
heavyGunner.validTargets.target2 = "Light Armor";
heavyGunner.weapons["Main Weapon"]["Weapon Type"] = "SAW M249";
heavyGunner.weapons["Main Weapon"]["Fire Range"] = 12;
heavyGunner.weapons["Secondary Weapon"]["Weapon Type"] = "";
heavyGunner.weapons["Secondary Weapon"]["Fire Range"] = "";
var sniper = object(soldier);
sniper.pointsCost += 30;
sniper.validTargets.target1 = "Infantry";
sniper.weapons["Main Weapon"]["Weapon Type"] = "Savage .308";
sniper.weapons["Main Weapon"]["Fire Range"] = 20;
sniper.weapons["Secondary Weapon"]["Weapon Type"] = "JCP .45";
sniper.weapons["Secondary Weapon"]["Fire Range"] = 3;
var demolitions = object(soldier);
demolitions.pointsCost += 30;
demolitions.validTargets.target1 = "Infantry";
demolitions.validTargets.target2 = "Light Armor";
demolitions.validTargets.target3 = "Artilery";
demolitions.validTargets.target4 = "Structures";
demolitions.weapons["Main Weapon"]["Weapon Type"] = "SMAW MK153";
demolitions.weapons["Main Weapon"]["Fire Range"] = 16;
demolitions.weapons["Secondary Weapon"]["Weapon Type"] = "M1014 Combat Shotgun";
demolitions.weapons["Secondary Weapon"]["Fire Range"] = 1;
var infantry = {
rifleman: rifleman,
heavyGunner: heavyGunner,
sniper: sniper,
demolitions: demolitions
};
console.log(infantry);
});
I start by creating an object function that accepts an object passed in, and sets it to the prototype of a constructor (that would allow me to create a new object linked to, and inheriting from, the initial passed in object) I initialized a solider object literal, and pass that into the object function while creating 4 new objects (rifleman, heavyGunner, sniper, demolitions) These four should inherit from and customize upon the soldier object. The way I understood inheritance is that the new objects (example. rifleman) would inherit properties from the old object (i.e. soldier) and change or add properties, affecting only the new (rifleman) object but not changing the old(solider) object. this works ok somewhat in my example, until it comes to nested objects. In the above example I have objects as values for some Object's properties. (i.e. validTargets and weapons) When I change or add these, all of the new objects seem to inherit the last declarations, from demolitions, as if demolitions is actually changing that part of the soldier object so that the other's inherit those properties. From my viewpoint, I expected these values to not be changed and that the 4 infantry types had no link to each other, but only to the soldier object. I apparently misunderstood something, or coded something wrong. Some minor notes: -I will be updating most of the "string" values to be objects, so for instance, the validTargets value of "Infantry" would actually be the infantry object, stating that any of the 4 solider types would be a valid target. - I intend to create weapons as their own viable objects in the future, and pass those objects instead of "strings" - I intend to extend this (once this is working) to create an armor object that contains armor type units, similar in structure to the infantry object. - If I can get this all to work, I may make this into a "simple" dice style battle game. but that is way off, I just want to get this nesting of objects to work with inheritance for now. Thanks in advance for any help you can provide. Here is a link to the "live" example. (not much different there except if you have firebug you can see the console.log method showing the objects, and how they are inheriting in properly from my POV.) Link to Live example... Blue Hey guys. I have a weird issue (you kind of have to see it for yourself to understand). If you double click on the next or previous button quickly (within 500 miliseconds of each other) it creates a double of the next slide. http://insidehb.com/imageofday/ Let me know if you can help. Thanks. Dear all I came across the following very simple code for dragging a square around using javascript. It is drawn on the html5 canvas. Despite being very simple it has certainly exposed some gaps in my pretty flakey javascript knowledge. I am generally ok with the idea of drag and drop (i.e. start drag on mouse click, stop drag on mouse release) but my questions are as follows: (1) I cannot see where the variable e is defined, yet it is used all the time. (2) In the init funciton at the bottom, an onmousedown listener seems to be attached to the canvas. However it equals the function myDown, but myDown doesn't have parentheses after it. So the myDown function is not actually going to be exectuted. So what is it doing instead? Thanks in advance. I have tried to research this myself but haven't had any success yet.

I've tried using Jquery $.ajax to bring in the data from a php file. It seems to work however it takes some time to load without a way to really give a progress meter. I was wondering what the fastest way to do this would be. For instance it loads and loads then after a long while the alert(); pops up and the data loads into the page. Ultimately i was thinking i could use the ajax request to read in the data from the mysql database server, then transfer it to localstorage, im using HTML5 primarily for the development also just for reference. Somewhat new to mobile development i was just wondering if anyone had a starting point for me to look at and go from there. Code: $(document).ready(function($){
var dataret = 0;
$.ajax({
type: 'POST',
url: 'mobile.php',
beforeSend: function(){
$('#status').show();
},
success: function(data){
//initialize localstorage here
alert('success');
// if it takes as long as it does, a few minutes, at least show a loading bar...
$('#progress').progressbar({
});
},
dataType: 'json'
});
});
Thanks in advance! Hi All.....I am new to javascript coding ...I am unable to forward from my jsp to servlet file via javascript below is my code....

Need to set the width of a Table that is being spit out by this god awful CMS... please help me... change the html attribute width! QUESTION 1: Hello. I would like to know if this is possible with Javascript, and if yes, if someone can please provide me with the code or point me in the right direction. Let me start of by saying that this is for an eBay listing. I know that they accept basic / limited javascript and if what I am asking is possible, I hope that it can work on eBay listings. I would like to know if it's possible to determine the dimensions of an image with Javascript from an Image url, and to then resize it or not based on the the size of the image. So, let's say this is the URL: www.adomainname.com/image.jpg and let's say that image is 1400 px x 1400 px. I would first like the javascript code to detect that size. I also would like the maximum dimension for any side of the image to be 600 px. If both sides of the image are over 600 px, for both sides to be reduced proportionally to 600 px or lower. If any one side of the image is larger than 600 px, the image is to be resized to 600 px or lower. If both sides are under 600 px, the image is to not be reduced. It would also be nice if it can detect whether the image is portion or landscape based on I guess the larger side, because an image at 600 px in height might be too big, but in width might be o.k. So, in this example (the 1400 px by 1400 px), the image is to be resized to 600 px x 600 px. For an image that's 300 px x 500 px, it should remain as such. For an image that's 400 px x 700 px, it should be resized to 400 / (700 / 600) px by 600 px, which is approximately 343 px x 600 px. I have looked a bit into this and I see things being mentioned about the image being loaded first completely on the screen, or about using server side language like PHP, and so on, but like I said, keep in mind that this is for eBay, and so I am limited. Note: The part that I am most interested in is in being able to detect the size / dimensions of the image. QUESTION 2: On a side note, does anyone know if it's possible to have a Javascript enlarging function for images, in which when one clicks on an image, it is enlarged, but either in a popup window that's smaller than the one behind it, and possibly centered, or by making the background go dark and then bringing up the enlarged image (is the latter done with Javascript; I have seen this effect for a while now and have always wondered.) |
