JavaScript - Help With Getting Onclick Event Handlers Out Of Html
I'm trying to figure out a way to put this in all js code with the onclick event handlers and the parameters. I have 3 links that switch the style of my page. Right now I have them working with inline event handlers. Here are my code snippets below.
HTML: Code: <head>
<link rel="stylesheet" href="style1.css" type="text/css" title="style1"/>
<link rel="alternate stylesheet" type="text/css" href="style2.css" title="style2" />
<link rel="alternate stylesheet" type="text/css" href="style3.css" title="style3" />
</head>
<div class="styleLinks">
<a href="#" id="style1" onclick="setStyleSheets('style1'); return false;">Style 1</a>
<a href="#" id="style2" onclick="setStyleSheets('style2'); return false;">Style 2</a>
<a href="#" id="style3" onclick="setStyleSheets('style3'); return false;">Style 3</a>
</div>
JS: Code:
function setStyleSheets(title) {
//set styles and set cookie
var i;
var attribute;
var today = new Date();
var expDate = new Date(today.getTime() + 7*24*60*60*1000);
var styleSelected = "";
if (title=="style2"){
styleSelected = "style2";
}
else if (title=="style3"){
styleSelected = "style3";
}
for(i=0; (attribute = document.getElementsByTagName("link")[i]); i++) {
if(attribute.getAttribute("rel").indexOf("style") != -1 && attribute.getAttribute("title")) {
attribute.disabled = true;
if(attribute.getAttribute("title") == title) attribute.disabled = false;
SetCookie ('style', styleSelected, expDate, "/");
}
}
}
Similar Tutorialshi, i need to be able to take the values from two text boxes and change the location of a sprite on my canvas, i've searched the internet and it doesnt really explain how to do it for me. here is my code: x: <input type="text" name="x" id="x"/><br /> y: <input type="text" name:"y" id="y"/><br /> <input type="submit" value="Submit" onClick="ChangeCo()" /><br /> function ChangeCo() { } and i need the function to take the x and y values from the text boxes and change the values of my variables: var block_x; var block_y; block_x = 290; block_y = 70; Thankyou in advance I have tried many conventional methods trying to get my javascript to work without using inline event handlers and for some reason the way my teacher shows us how to do it is not working for me. Any help would be much appreciated. Here is were I left off. The top part of this code is were I was trying to get the event handler to work. Code:
function setClock() {
document.getElementById('custname').focus();
digitalClock();
}
var digital;
function stop(){
clearTimeout(digital);
}
function digitalClock(){
var newDate = new Date();
var hour, minute;
var second;
var time = " ";
hour = newDate.getHours();
minute = newDate.getMinutes();
second = newDate.getSeconds();
if (hour <= 9) hour = "0" + hour;
if (minute <= 9) minute = "0" + minute;
if (second <= 9) second = "0" + second;
time += hour + ":" + minute + ":" + second;
document.getElementById('dClock').value = time;
digital = setTimeout("digitalClock()", 1000);

good day: I'm using an ajax script that receives a value into an input box and thus performs a function. I need to invoke the function immediately after the input box has a value. Currently the box has to lose focus in order for the function to work. What is the correct event handler for this to work? I have this now PHP Code: onkeyup="showResult2(this.value)" which is obviously not what I need. This is the ajax PHP Code: <script type="text/javascript"> function showResult2(strs) { if (strs.length==0) { document.getElementById("livesearch2").innerHTML=""; document.getElementById("livesearch2").style.border="0px"; return; } if (window.XMLHttpRequest) {// code for IE7+, Firefox, Chrome, Opera, Safari xmlhttp=new XMLHttpRequest(); } else {// code for IE6, IE5 xmlhttp=new ActiveXObject("Microsoft.XMLHTTP"); } xmlhttp.onreadystatechange=function() { if (xmlhttp.readyState==4 && xmlhttp.status==200) { document.getElementById("livesearch2").innerHTML=xmlhttp.responseText; document.getElementById("livesearch2").style.border="1px solid #A5ACB2"; } } xmlhttp.open("GET","getOilChangeDate.php?q="+strs,true); xmlhttp.send(); } </script> Any thoughts on this! Mossa Today I have been embedding some Google Maps on my website. When I got around to putting in event handlers for markers on the map I ran into some trouble with how to declare them in the way I have the map setup. The issue is that I have an array, label, and want to indicate a single element from that array to the event handling function. But the declaration of this seems tricky. The code in question are the two lines like this one in the script below: GEvent.addListener(marker[i], 'mouseover', function() { map.addOverlay(label[i]); }); Specifically, the problem is with function() { map.addOverlay(label[i]); because I don't want label[i] to be used, but whatever value i has should be substituded in there. But since this is a function being declared and not actually executed the value for i does not get used. I've been able to get it to work by using eval() to force the actual value of i into the code, like so: eval('GEvent.addListener(marker[i], \'mouseout\', function() { map.removeOverlay(label['+i+']); });'); but am wondering if there is a better solution? Here's a section of my script showing the issue in context. You can see that i is incremented with a loop and used as the index of a few arrays. Code: for (i = 0; i < buildings.length; i++) {
icon[i] = new GIcon();
icon[i].image = 'http://labs.google.com/ridefinder/images/mm_20_red.png';
icon[i].iconSize = new GSize(12, 20);
icon[i].iconAnchor = new GPoint(6, 20);
map.addOverlay(marker[i] = new GMarker(new GLatLng(buildings[i][1], buildings[i][2]), {icon:icon[i]}));
label[i] = new ELabel(new GLatLng(buildings[i][1], buildings[i][2]), '<nobr>'+buildings[i][3]+'<\/nobr>', 'maplabel');
GEvent.addListener(marker[i], 'mouseover', function() { map.addOverlay(label[i]); });
GEvent.addListener(marker[i], 'mouseout', function() { map.removeOverlay(label[i]); });
}
Hi, I'm having two issues: First, is there an easier way for my showValue function to display the image file name without running a bunch of if statements? I tried doing something like document.getElementById('imgFile').value = imgArray[n]; but that did not seem to work. Second, I'm trying to have the image file name change in my textbox when I click any button. I've accomplished this with onblur, but that only works if I click on the textbox. I'd like it to just change automatically. Thanks for you help! Code:

can someone please explain the code in this link. Just this small bit since i seen it in a few different places. it starts off with if (!e) ... please explain wth that means thank you so much heres the link - http://www.w3schools.com/js/tryit.as...ent_srcelement Well just came to notice this lack of tools on javascript to manage uploads or downloads while working on my new project. I've been trying different ways to get the upload progress, stimated time left, upload speed average, but everything I have done was somehow dirty. I have spent the last two days trying to get a flash file do this for me, and there is always an issue and you have to get a tricky solution to get something that should be a native javascript support at this age of the web. What do you think guys, isn't the web mature enought to get a decent upload / download progress functions? What are big guys doing, youtube, google, flickr? I have a web page with two forms, when I click the button on one of the forms, the onclick event goes to a javascript that emails the first form and then the second form. This is correct, this is the way I want this to work. It's simple, it's easy, it works! However, it only works in FireFox and Internet Explorer, it will not work in Google Chrome browser. I've spent many hours trying lots of various ways to implement this so I'm not interested in speculating about possible solutions that might work, I've already tried too many of those. Also, it needs to work this way, not combining the forms, etc. Does anyone have any tried and tested solutions that work with Chrome? Thanks, in advance, for your expert advice. I know I can always rely on EE when all else fails. I know somebody here can solve this problem. Code: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">

Hello all, This is a follow up with a new question from a post I did last week. http://www.codingforums.com/showthre...098#post956098 I have an experimental website where I have music recordings. url removed When you open the site, each page uses a piano keyboard graphic to navigate between pages. If you click on a key that says "Jukebox" it will open a small window and continuously play tunes. The way the jukebox works basically is, when you click the jukebox key it calls an html file which contains the information needed to play the first song. When that song is finished it calls another html file with the information to play the second song and so on. Each html file contains an embedded Windows Media Player in it. I would like to give visitors the option to use the QuickTime player. So I can have one key in the keyboard graphic that say “Jukebox – for Windows Media Players” and then another key in the graphic that would say “Jukebox – for QuickTime players”. I would like to use both keys to call the same html file. So, in the file I would like to: 1. Determine which key was pressed in the graphic. (how to send a parameter from the keyboard graphic file indicating which key was pressed) 2. With that parameter I would then like to invoke the appropriate player. (how to receive that parameter) After the help I received last week I have my html in the keyboard graphic file set up as follows to call the first html file with the first song: Code: <AREA SHAPE="rect" HREF="#" onclick="window.open('ShirleyLee.html','jukebox',
'toolbar=0,location=0,directories=0,status=0,menubar=0,scrollbars=1
,resizable=0,copyhistory=0,left=0,top=0,screenX=0,screenY=0,width=410
,height=300');return false;"onMouseover="document.roll.src=F1
_Down.src"onMouseout="document.roll.src=KeysUp.src"COORDS="
233,344,335,384" NAME="roll"ALT="F1">
I think we would be talking about the use of forms but not sure how to incorporate along with an onclick event.... The reason for this post is just to get some high level discussion ideas so that I can take that and go research how to do it. I could ask specifics later. Thanks! Dan Hi, New to javascript. Doing web page with ASP/VB.NET. Have text boxes for UI on page. Two command buttons - Submit (for db update) and Cancel. I need the Cancel button to prompt the user to verify cancellation. Need OK/Cancel buttons on alert. If user selects Cancel-no action. If user selects OK then I want the text boxes cleared of user text input and focus returned to first text box. I think this may be the code but do not know how to apply it. function Clear() { var res=window.confirm("Please confirm cancellation-text boxes will be cleared"); if(res==true) { document.getElementById("StrtDte").value=""; document.getElementById("EndDte").value=""; document.getElementById("txtProjRegHrsAl").value=""; document.getElementById("txtProjOTHrsAl").value=""; document.getElementById("ddlRAS").focus(); } } Is this code valid or invalid for the events I need? How do I set it to fire when user clicks the ASP Cancel button? Thanks, John Hello forum, My name is juan and recently started html programming. I have a web page with a drop box with the name of states. Code: <option value="">Alabama</option> <option value="">Alaska</option> I can add a onclick="code here" to the tag so that when the drop box alabama is selected it triggers the onclick event. Im using Ibox in order to have a image of the state open. Code: <a href="images/large/image_1b.jpg" rel="ibox" title="alabama at 1024x450!"><img src="images/small/image_1.jpg" alt=""/></a> the above is a <a> link tag correct? How do I go bout adding the above code into the onclick event? here the deal ,,I've solved all but this problem in my script i have my page setup with 1 iframe and the main html the code below is exactly how the page will show up in the iframe, you can copy and paste the whole thing and save it as a htm file to view if needed.. I need a way to catch the clicks that happen within the iframe but from the main section of the page..heres why! this is inserted at the top of the page if(top.location==self.location){top.location="RefESI_search.asp";} just above top.document.reset.RefCat.value= I can get the page to load even with this in the iframes ..but for the purposes of this i left it out so the page would load ok for anyone thats gonna try and help . theres only 2 links in the code.. hopefully whatever will hopefully solve this problem will be able to tell which links were clicked,and i can can point them to the apropriate links. I've looked thru alot of the threads so i know there are some extremely brite ppl in here that can knock this problem out of the ball park very easily.. you can grab the styles sheet from here https://www.docs.sony.com/reflib/Style_esi.css Code: <html>

Hi, I am trying to get my onclick event to handle both of the function below. I want the event to return false (stop executing) if any of the two functions return false. Here is my code: Code: function isNumeric(elem, helperMsg){
var numericExpression = /[0-9]+/;
if(!elem.value.match(numericExpression)){
SaveRecord();
return true;
}else{
alert("You cannot enter numbers in the Comments field.");
return false;
}
}
function lengthRestriction(elem, min, max){
var x = elem.value;
if(x.length >= min && x.length <= max){
SaveRecord();
}else{
alert("Please enter between " +min+ " and " +max+ " characters in the Issue Number field");
}
}
Please help me. Thank you. I assum the following html code: <div id="id1" onclick="click()">A<div> <div id="id2" onclick="click()">B<div> Do you know how to get ID = id2 when I onclick on A? I'm having an issue where a programmatic click event is not behaving the same way the cursor click event is. A cursor click returns the correct object from GetObject(). The programmatic click triggered by a USB device is returning undefined from GetObject(). How can this be resolved? Edit: It appears that it does not recognize eval(document.getElementById(gButtonList[gButtonId])).onclick(); as an event. Why is this? How can I get it to recognize it? Edit2: Resolved it myself. See green text below. TestPage.htm: Code: <script language="JavaScript" src="../bin/USBHelperFile.js"></script>
<script language="JavaScript" type="text/JavaScript">
function BuildButtons()
{
for (var i = 0; i < testArray.length; i++)
{
// Create Div [Buttons created programmatically]
var divNode = document.createElement('div');
divNode.id = 'div' + i;
divNode.onclick= ClickFunction;
etc...
}
}
function ClickFuntion(nodeButtonNum)
{
alert(GetObject());
Returns the index for a cursor click. Returns undefined for
the programmatic click triggered by the USB device
}
function GetObject()
{
var node = event.srcElement;
return node;
}
</script>
USBHelperFile.js: Code: This JS file works with a USB hardware device that can navigate
through divs and click them when they have focus.
function HelperFunction(keyCommand)
{
switch (keyCommand)
{
case: "click":
// eval(document.getElementById(gButtonList[gButtonId])).onclick();
var target = eval(document.getElementById(gButtonList[gButtonId]));
target.fireEvent("onclick");
break;
}
}
I've got a checkbox that, when clicked, displays new text inputs. However, when I "uncheck" the box, the fields don't disappear unless I reload the entire page. What code can I add to reset the box to null when it is unchecked? Here's the function code I have: Code: <script>
function showUserReg() {
document.getElementById("userReg").style.display = "inline";
}
</script>
And here's the inline code: Code: <input type="checkbox" name="additional" value="userRegister" onclick="showUserReg()"/> Yes! Register me now!<br/> <span id = "userReg" style="display:none"> <table class="nobord" align="center"> <tr> <td>Choose a username:</td> <td><input type="text" name="username" size="35"/></td> </tr> <tr> <td>Choose a password:</td> <td><input type="password" name="password" size="35" maxlength="20"/></td> </tr> <tr> <td>Confirm password:<font color="red">*</font></td> <td><input type="password" name="password" size="35" maxlength="20"/></td> </tr> </table> </span> Thanks for any help. I was trying to help someone on another forum and seem to have run into a brick wall. The main problem that has got me stumped at the moment is that clicking on the images in the 1st tab work fine. However the subsequent tab selections and clicks do not change the "bigImage" correctly (not at all). Perhaps some other more experienced forum members can identify what I doing wrong at this time. I believe it is in my set-up of the onclick events in the "onload=" section, but I not the best at this event stuff yet! Code: var sel, tmp, elem;
var j=0;
for (var i=0; i<imgGroupArray.length; ++i) {
sel = document.getElementById('imgGroup'+i).getElementsByTagName('img');
while (elem=sel[j++]) { elem.onclick = function() { setBigImage(this.src); } }
}

Hi I would like to use javascript to control what tooltip displays when a tab is rolled over depending on which tab was clicked. Code: <li id='1tab_1a' class='selected'><a id='1link_1a' title="Customer Info Screen"><span >Customer Info</span></a></li> <li id='1tab_1b' ><a id='1link_1b' title="Order Detail" ><span>Order</span></a></li> <li id='1tab_1c' ><a id='1link_1c' title="Phone Detail" ><span>Phone: 7093521232</span></a></li> For example when the Customer Info tab is selected I would like the tooltips to be like above but when Order is the tab selected I would like the tooltip to say Customer Info Detail, Order Detail Screen, and Phone Detail. How could I use an onclick event to control what tooltip is being displayed depending on which tab is selected? I have about 20 sets of customer info and sometimes not everyone contains all of the tabs and I would also like to be able to add more customers. |
